SEATS AND RESTRAINTS

Safety Restraint Belts

Safety belts have proven to be the single most effective means available for reducing the potential for either death or personal injury in motor vehicle accidents. Unbelted riders could be thrown into the windshield or other parts of the cab or could be thrown out of the cab. They could strike another person. Injuries can be

much worse when riders are unbelted. Always fasten your seat belt and be sure anyone riding with you does the same. Therefore, read the following instructions and always observe user warnings pertaining to safety belts.

WARNING! Do not drive vehicle without your seat belt and your riders belts fas- tened. Riding without a safety belt properly fastened can lead to death or personal injury in an emergency.

WARNING! In vehicles equipped with passenger seat swivel function, the seat belts will only perform their intended func- tion when the seat is facing forward. Failure to comply can lead to death or personal injury in an emergency.

Your vehicle is equippedwith a seat belt indicator in the warning light display

above the speedometer/tachometer (see Seat Belt, Fasten on page 3-27).

SEATS AND RESTRAINTS

WARNING! Do not remove, modify, or replace the tether belt system with a differ- ent tether system. A failed or miss- ing tether belt could allow the seat base to fully extend in the event of an accident. Failure to comply may result in death or personal injury.

WARNING! Failure to adjust tether belts properly can cause excessive movement of the seat in an accident. Tether belts should be adjusted so that they are taut when the seat is in its most up- ward and forward position. Failure to comply may result in death or per- sonal injury.

To adjust an external tether belt:

Make sure that the tether belt is attached to the cab floor and seat frame. It should be routed through the buckle on each side.

Often the attachments are made using a split-type hook. Make sure both halves of the hook are around the anchor bracket.

To lengthen the tether, turn the buckle to a right angle to the webbing. Then pull the buckle. To shorten the tether, pull on the strap.

Komfort-Latch Feature

Your vehicle includes a feature designed to eliminate cinching and provide improved safety and comfort. Cinching is the condition where a belt becomes continually tighter around you during a rough, bouncy ride. The need for this feature increases with rough road conditions, particularly over long distances.

To eliminate cinching, simply activate the Komfort-Latch feature located on the seat belt webbing at the appropriate time:

1. Adjust the seat to its proper driving position.

2. Latch the seat belt.

3. If available, adjust the seat belt height adjuster to a comfortable driving position.

the optional sleeper) should hold a combined total not exceeding 5 lbs (2.2 kg) per compartment.

Safety Restraint Tips Do not wear a belt over rigid or

breakable objects in or on your clothing, such as eye glasses, pens, keys, etc., as these may cause injury in an accident.

Any authorized person sleeping in your vehicle while it is moving should use the bunk restraint.

Any authorized person sitting in the sleeper area on the sofa bed (if equipped) while it is moving should wear a seat belt.

A responsible operator sees to it that everyone in the vehicle rides or sleeps safely. The operator is responsible to inform any passengers or co-drivers how to properly use the seat belts and bunk restraint in the vehicle.

Do not strap in more than one person with each belt.

Keep seat belt and bunk restraint buckles free of any obstruction that may prevent secure locking.

Damaged or worn belts in the cab or sleeper, subjected to excessive stretch forces from normal wear, must be replaced. They may not protect you if you have an accident.

Any belts or restraints that have been subjected to an accident should be inspected for any loose (attaching) hardware or damaged buckles.

If belts show damage to any part of assembly, such as webbing, bindings, buckles or retractors, they must be replaced.

Do not allow safety belts (seat or bunk) to become damaged by getting caught in door, bunk or seat hardware, or rubbing against sharp objects.

SEATS AND RESTRAINTS

All belts must be kept clean or the retractors may not work properly.

Never bleach or dye seat or bunk restraint belts: chemicals can weaken them. Do, however, keep them clean by following the care label on the belts. Let them dry completely before allowing them to retract or be stowed away.

Make sure the seat belts and bunk restraint of the unoccupied passenger seat or bunk is fully wound up on its retractor or is stowed, so that the belt or restraint tongue is in its properly stowed position. This reduces the possibility of the tongue becoming a striking object in case of a sudden stop.

Do not modify or disassemble the seat belts or bunk restraint in your vehicle. They will not be available

to keep you and your passengers safe.

If any seat belt or bunk restraint is not working properly, see an authorized dealer for repair or replacement.

START-UP

START-UP

Introduction

The following section covers start-up procedures for getting your vehicle ready for the road.

Safe Vehicle Operation

For your safety, as well as those around you, be a responsible driver:

If you drink alcohol, do not drive.

Do not drive if you are tired, ill, or under emotional stress.

Safe driving is only possible with the proper concentration on the driving task. Keep distraction to a minimum to improve your concentration. Examples of distractions may include radio controls, GPS navigation controls, cellular telephone calls, cellular text messages, reading or reaching for something on the floor. Minimizing your distractions will improve safe driving and will help avoid an accident involving death or personal injury.

Be aware of local regulations that may prohibit the use of cellular telephones while driving. In addition to being an unsafe practice, it may be against local

or federal ordinances to use cellular devices while operating the vehicle.

Much has gone into the manufacturing of your vehicle including advanced engineering techniques, rigid quality control, and demanding inspections. These manufacturing processes will be enhanced by you, the safe driver, who observes the following:

Knows and understands how to operate the vehicle and all its controls.

Maintains the vehicle properly.

Uses driving skills wisely.

For more information, refer to Department of Transportation Regulation 392.7, which states that interstate commercial motor vehicles are not to be driven unless the driver is sure that certain parts and accessories are in working order.

(03/17) Y53-6076-1B1 1-31

START-UP

WARNING! The use of alcohol, drugs, and cer- tain medications will seriously im- pair perception, reactions, and driv- ing ability. These circumstances can substantially increase the risk of an accident. Failure to comply may re- sult in death, personal injury, equip- ment or property damage.

Do not drink alcohol and drive. Your reflexes, perceptions, and judgment can be affected by even a small amount of alcohol. You could have a serious or even fatal accident, if you drive after drinking. Please do not drink and drive or ride with a driver who has been drinking.

WARNING! Do not text and drive. Your reac- tion time, perceptions and judgment can be affected while texting or us- ing any other form of mobile mes- saging while driving. Failure to com- ply may result in death, personal in- jury, equipment or property damage.

Vehicle Loading

Compare your vehicle's load capacity with the total load you are carrying. If adjustments need to be made, make them, do not drive an overloaded vehicle. If you are overloaded or your load has shifted, your vehicle may be unsafe to drive.

WARNING! Do not exceed the specified load rat- ing. Overloading can result in loss of vehicle control, either by causing component failures or by affecting vehicle handling. Exceeding load ratings can also shorten the service life of the vehicle. Failure to comply may result in death or personal in- jury.

The gross vehicle weight rating (GVWR), or the maximum front and rear gross axle weight ratings (GAWRs) are determined by the

1-32 Y53-6076-1B1 (03/17)

START-UP

components installed from the factory on to the vehicle and their designed specifications. (Axle weight ratings are listed on the driver's door edge.)

The following are some definitions of weight you should know:

GVWR: is the Gross Vehicle Weight Rating. This is the MAXIMUM WEIGHT your vehicle is allowed to carry, including the weight of the empty vehicle, loading platform, occupants, fuel, and any load. Never exceed the GVWR of your vehicle.

GCW: is the actual combined weight, or Gross Combination Weight (GCW), of your vehicle and its load: vehicle, plus trailer(s), plus cargo.

GAWR: is the Gross Axle Weight Rating. This is the total weight that one axle is designed to transmit to the ground. You will find this number listed on the driver's door edge.

Load Distribution: be sure any load you carry is distributed so that no axle has to support more than its GAWR.

WARNING! An unevenly distributed load or a load too heavy over one axle can af- fect the braking and handling of your vehicle, which could result in an ac- cident. Even if your load is under the legal limits, be sure it is distributed evenly. Failure to comply may result in death, personal injury, equipment or property damage.

START-UP

Emergency Equipment

It is good practice to carry an emergency equipment kit in your vehicle. One day, if you have a roadside emergency, you will be glad the following items are with you:

window scraper

snow brush

container or bag of sand or salt

emergency light

warning triangles

small shovel

first aid kit

fire extinguisher

vehicle recovery hitches (see Vehicle Recovery Guidelines on page 2-15 for details).

Driver's Check List

To keep your vehicle in top shape and maintain a high level of safety for you, your passengers, and your load, make a thorough inspection every day before you drive. You will save maintenance time later, and the safety checks could help prevent a serious accident. Please remember, too, that Federal Motor Carrier Safety Regulation 392.7 requires a pre-trip inspection and so do commercial trucking companies.

You are not expected to become a professional mechanic. The purpose of your inspections is to find anything that might interfere with the safe and efficient transportation of yourself, any passengers, and your load. If you do find something wrong and cannot fix it yourself, have an authorized dealer or qualified mechanic repair your vehicle right away.

The following operations are to be performed by the driver. Performing these checks and following the maintenance procedures in the Maintenance and Consumer Information manual will help keep your vehicle running properly.

1-34 Y53-6076-1B1 (03/17)

START-UP

Approaching Your Vehicle

Check the overall appearance and condition. Are windows, mirrors, and lights clean and unobstructed?

Check beneath the vehicle. Are there signs of fuel, oil, or water leaks?

Check for damaged, loose, or missing parts. Are there parts showing signs of excessive wear or lack of lubrication? Have a qualified mechanic examine any questionable items and repair them without delay.

Check your load. Is it secured properly?

Daily Checks

Engine Compartment Checks - Daily

1. Engine Fluid Levels - add more if necessary.

a. Engine oil

b. Coolant (check while engine is cold)

c. Power steering fluid level

2. Engine Belt - check tension and condition of belts.

a. See the Accessory Drive Belts topic in the Maintenance Manual for further information on checking belt tension.

b. Replace belts that are cracked torn or broken.

3. Fuel Filter/Water Separator Draining - check and drain. Depending on the fuel storage facility, more frequent draining may be required.

4. Windshield washer reservoir fluid level - fill if necessary.

5. Battery Cables - check the condition of the battery and alternator cables for signs of chafing or rubbing. Make sure that all clamps (straps) holding the cables are present and in good working order.

6. Hood closed before entering cab. Is it latched properly?

7. Check brake lines and hoses.

8. Check the steering components (pitman arm, draglink, power steering hoses, etc.).

Chassis and Cab Checks - Daily

Before entering the cab and operating the vehicle, check the following equipment for proper maintenance:

1. Lights - are any exterior lights cracked or damaged?

(03/17) Y53-6076-1B1 1-35

START-UP

Perform an exterior light test using the dash mounted switch next to the steering wheel. See Exterior Lighting Self-Test on page 3-60.

2. Windows and Mirrors - are they clean and adjusted properly?

3. Tires and Wheels - are they inflated properly? Are all wheel cap nuts in place and torqued properly - tighten if necessary. Check front wheel bearing oil levels. Inspect all tires and wheels for damage - correct if found.

4. Suspension - check for loose or missing fasteners. Check damage to springs or other suspension parts such as cracks, gouges, distortions, bulges or chafing.

5. Brake Components - check lines, linkages, chambers, parking and service brake operation.

6. Air System - are there leaks?

Air Tanks - drain water from all air tanks. Make sure the drain cocks are closed. This procedure is also required for air suspension tanks equipped with automatic drain valves.

7. Steps and Handholds - check for worn surfaces and loose or missing fasteners (which includes any fuel tank steps).

8. Fluid Tanks (Fuel, DEF, etc.) - check underneath the vehicle for signs of fluid leaks. If any are found, correct before operating the vehicle.

9. Fuel Tank Hardware - is the tank fill cap secure? Are the tank straps tight? Is the strap webbing in place?

WARNING! Diesel fuel in the presence of an ig- nition source (such as a cigarette) could cause an explosion. Do not re- move a fuel tank cap near an open flame. Use only the fuel and/or addi- tives recommended for your engine. A mixture of gasoline or alcohol with diesel fuel increases this risk of ex- plosion. Failure to comply may result in death, personal injury, equipment or property damage. See Refueling on page 4-51, for more information.

10. Trailer Connections - are they secure and the lines clear? If they are not being used, are they stored properly?

a. Is the trailer spare wheel secure and inflated?

b. Is the landing gear up and the handle secured?

1-36 Y53-6076-1B1 (03/17)

Low Air Alarm Turns On

1. Slow down carefully.

2. Move a safe distance off the road and stop.

3. Place the transmission in neutral (park with automatic transmissions, if equipped) and set the parking brake. (Refer to Parking Brake on page 4-34 and Operating the Transmission on page 4-18, for transmission shifting and parking brake information.)

4. Turn OFF the engine.

5. Turn ON the emergency flasher and use other warning devices to alert other motorists.

(03/17) Y53-6076-1B1 2-3

2

WHAT TO DO IF...

WARNING! If the air pressure falls below 60 psi (414 kPa) the spring brakes may stop the vehicle abruptly, which could cause an accident resulting in death or personal injury. Ob- serve the red warning lamps on the gauges. If one comes on, do not continue to drive the vehicle until it has been properly repaired or ser- viced.

If the light and alarm do not turn off at startup, do not try to drive the vehicle until the problem is found and fixed. (Refer to Operating the Brake System on page 4-21, for more brake information.)

Stop Engine Lamp Turns On Stop Engine Lamp - If the Stop Engine warning lamp illuminates, it means you have a serious engine system problem.

WARNING! This should be considered an emer- gency. You should stop the vehicle as safely as possible and turn OFF the ignition. The vehicle must be serviced and the problem corrected before driving again. Failure to do so may cause severe engine or DPF damage, or cause an accident which may result in death or personal in- jury.

Engine Oil Pressure Lamp Turns On

Engine Oil Pressure Lamp - If the oil pressure suddenly drops, or the audible alarm and engine oil pressure warning light come on while driving, do the following:

1. Slow down carefully.

2. Move a safe distance off the road and stop.

3. Place the transmission in park and set the parking brake. (See Parking Brake on page 4-34 and Operating the Transmission on page 4-18, for transmission shifting and parking brake information.)

4. Turn OFF the engine.

5. Turn ON the emergency flasher and use other warning devices to alert other motorists.

2-4 Y53-6076-1B1 (03/17)

2

WHAT TO DO IF...

6. Wait a few minutes to allow oil to drain into the engine oil pan, and then check the oil level. (See Inspection of the Engine Oil on page 4-54.

7. Add oil if necessary. If the problem persists, contact an authorized dealer as soon as possible.

CAUTION Continuing to operate your vehicle with insufficient oil pressure may cause severe engine damage or cause an accident which may result in equipment or property damage.

It is important to maintain oil pressure within acceptable limits. If oil pressure drops below the minimum psi (kPa) a Red Warning Lamp on the oil pressure gauge will illuminate and the Stop Engine Lamp will come ON.

Engine is Overheating

The cooling system may overheat if the coolant level is below normal or if there is sudden loss of coolant, such as a split hose. The system may also temporarily overheat during severe operating conditions such as:

Climbing a long hill on a hot day

Stopping after high-speed driving

If either one of the above occurs, DO NOT TURN OFF THE ENGINE unless: a) the Low Water warning device indicates a loss of coolant, b) the Red Warning lamp (on the gauge) and Check Engine lamp comes ON, c) the Buzzer sounds showing an overheat condition, or d) if you have any other reason to suspect the engine may be overheating - follow these steps:

1. Reduce engine speed and stop. When stopped, place the transmission in Neutral and set the

parking brake. Keep the engine running.

2. Check to ensure the Oil Pressure Gauge reads normal. (See Engine Oil Pressure Gauge on page 3-11, for further information.)

3. Make sure the engine fan is turning by switching the Engine Fan Switch from AUTO to MAN (Manual).

4. Increase the engine speed to about one-half of full operating speed, or 1,100 to 1,200 rpm, maximum.

5. Return the engine speed to normal idle after 2 or 3 minutes.

6. Monitor the engine temperature. After the temperature returns to normal, allow the engine to idle 3 to 5 minutes before shutting it off. This allows the engine to cool gradually and uniformly.

(03/17) Y53-6076-1B1 2-5

2

WHAT TO DO IF...

7. If overheating came from severe operating conditions, the temperature should have cooled by this time. If it has not, stop the engine and let it cool before checking to see if the coolant is low.

Check the coolant level after each trip when the engine has cooled. The coolant level should be visible within the surge tankadd coolant if necessary. See Topping Off on page 4-57 in , for instructions on checking and filling the coolant expansion tank.

WARNING! To reduce the chance of death, personal injury, fire and/or vehicle damage from overheated engines, never leave the engine idling without an alert driver present. If the en- gine should overheat, as indicated by the engine coolant temperature light, immediate action is required to correct the condition. Continued unattended operation of the engine, even for a short time, may result in serious engine damage or a fire. Failure to comply may result in per- sonal injury, death, equipment or property damage.

WARNING! Do not remove the radiator fill cap while the engine is hot. Scalding steam and fluid under pressure may escape. You could be badly burned. Failure to comply may result in death or personal injury.

Fuse or Relay Blows

Fuses, circuit breakers, and relays are located in the Power Distribution Box to the left of the steering column behind the clutch pedal. Additional fuses are located in the engine compartment (drivers side bulkhead) and also in the sleeper under bunk storage compartment.

WHAT TO DO IF...

Fuse Inspection and Replacement

All the electrical circuits have fuses to protect them from a short circuit or overload. If something electrical on your chassis stops working, the first thing you should check for is a blown fuse.

1. TurnOFF all lights and accessories and remove the ignition key to avoid damaging the electrical system.

2. Determine from the chart on the fuse panel which fuse controls that component.

3. Remove that fuse and see if it is blown.

1 Blown

If it is blown, replace it with a fuse of the same rating.

If a fuse of the same rating is not available, a fuse of a lower rating may be temporarily substituted. You can also use a fuse from a circuit you can do temporarily without (for example an accessory circuit or radio).

CAUTION When replacing a failed circuit breaker, always use an approved circuit breaker with a current rat- ing equal to or less than the circuit breaker being replaced. Only use the approved Type II modified re- set circuit breakers. NEVER use a Type I (automatic reset) or Type III (manual reset) circuit breaker. A fuse with a current rating equal to or less than the circuit breaker being replaced can also be used.

JUMP STARTING VEHICLES

JUMP STARTING VEHICLES

Introduction

Jump starting a vehicle is not a recommended practice due to the various battery installations and electrical options.

However, if your battery is discharged (dead), you may be able to start it by using energy from a good battery in another vehicle. This is termed jump starting. Be sure to follow the precautions and instructions below.

WARNING! Batteries contain acid that can burn and gasses that can explode. Ignor- ing safety procedures may result in death, personal injury, equipment or property damage.

WARNING! Never jump start a battery near fire, flames, or electrical sparks. Bat- teries generate explosive gases that could explode. Keep sparks, flame, and lighted cigarettes away from batteries. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING! Never remove or tamper with battery caps. Ignoring this could allow bat- tery acid to contact eyes, skin, fab- rics, or painted surfaces. Failure to complymay result in death, personal injury, equipment or property dam- age.

Be careful that metal tools (or any metal in contact with the positive terminal) do not contact the positive battery terminal and any other metal on the vehicle at the same time. Remove

metal jewelry and avoid leaning over the battery.

(03/17) Y53-6076-1B1 2-11

2

JUMP STARTING VEHICLES

To Jump Start your Vehicle

WARNING! When jump starting using a battery booster, it is best to jump start with an equivalently powered vehicle. Verify that the booster battery has the same volt and CCA specifica- tions as the dead battery before attempting to jump start. Failure to comply may cause an explosion resulting in death, personal injury, equipment or property damage.

CAUTION Applying a higher voltage booster battery may cause expensive dam- age to sensitive electronic compo- nents, such as relays, Electronic Control units or electronics in gen- eral. Failure to comply may result in equipment damage.

CAUTION Improper hook-up of jumper cables or not following these procedures can damage the alternator or cause serious damage to both vehicles.

WARNING! Heed all warnings and instructions of the jumper cable manufacturer. Failure to comply may result in death, personal injury, equipment or property damage.

Preparing the vehicles:

1. Remove any personal jewelry that may come in contact with the battery terminals.

2. Select a jumper cable that is long enough to attach to both vehicles in a way that ensures neither vehicle touches each other.

3. Position the two vehicles together, but do not allow them to touch.

4. Turn OFF all lights, heater, radio, and any other accessory on both vehicles.

5. Set the parking brakes: pull out the Yellow button located on the dash.

6. Shift the transmission into park position or neutral for manual transmissions. (See Operating the Transmission on page 4-18 and Parking Brake on page 4-34, for transmission shifting and parking brake information.)

JUMP STARTING VEHICLES

7. If either vehicle is equipped with battery disconnects ensure they are in the "OFF" position prior to connecting the two vehicles.

Connect the batteries:

1. Attach one end of a jumper cable to the positive (+) terminal of the discharged (dead) battery. This will have a large red + or P on the battery case, post, or clamp.

2. Attach the other end of the same cable to the positive (+) terminal of the good (booster) battery.

3. Attach the remaining jumper cable FIRST to the negative (-) terminal (black or N) of the good battery.

4. Attach the other end of the negative cable to a bare metal part not bolted to the engine block.

NOTE Always connect positive (+) to positive (+) and negative (-) to negative (-).

5. If either vehicle is equipped with battery disconnects, ensure that they are in the "ON" position.

6. Start the vehicle that has the good battery first. Let it run for 5 minutes.

7. Start the vehicle that has the discharged (dead) battery.

If the engine fails to start, do not continue to crank the starter but contact the nearest authorized dealer.

JUMP STARTING VEHICLES

Remove jumper cables:

WARNING! When disconnecting jumper cables, make sure they do not get caught in any moving parts in the engine com- partment. Failure to comply may re- sult in death, personal injury, equip- ment or property damage.

Reverse the above procedure exactly when removing the jumper cables. With engine running, disconnect jumper cables from both vehicles in the exact reverse order, making sure to first remove the negative cable from the vehicle with the discharged battery.

VEHICLE RECOVERY AND SPRING BRAKES

VEHICLE RECOVERY AND SPRING BRAKES

Vehicle Recovery Guidelines

Your vehicle is equipped with removable Recovery Hitches, designed for short distance recovery purposes only. Use only the provided hitches, according the following instructions. When using this connection, do not transport your vehicle over long distances. (If your vehicle does not have the proper hitches, contact your dealer.)

All lubricating and clutch application oil pressure is provided by an engine-driven pump, which will not work when the engine is stopped. You could seriously damage your vehicle by towing it with the driveline connected and the drive wheels on the ground. Worse, when vehicles are towed, either by wrecker or piggyback,

the lubricant in the top front of the drive axle will drain to the rear. This will leave the top components dry. The resulting friction may damage them. Always remove the main drive axle shafts before towing your vehicle.

CAUTION Remove the drive axle shafts or lift the driving wheels off the ground be- fore towing the vehicle. Towing the vehicle with either the wheels on the ground or the axle shafts in the axles will cause damage to the axle gears.

CAUTION If your vehicle has aMeritor axle with a driver-controlled main differential lock, install the caging bolt before removing the axles for towing, see Driver Controlled Main Differential on page 2-18. Installing the caging bolt prevents damage by locking in- ternal axle components in position.

CAUTION Connect only to the Recovery Hitches, see Vehicle Recovery Guidelines on page 2-15. Connec- tions to other structural parts could damage the vehicle. Do not attach to bumpers or brackets. Use only equipment designed for this pur- pose. Failure to comply may result in equipment damage.

VEHICLE RECOVERY AND SPRING BRAKES

Recovery Procedure

1. Review and understand all the cautions and warnings of this section, see Vehicle Recovery Guidelines on page 2-15.

2. Install the recovery hitches, see Recovery Hitch Installation on page 2-18.

3. Disconnect the drive axle shafts and cover the open hubs. This is necessary because if the transmission is driven by the driveshaft (rear wheels on the ground), no lubricant will reach the gears and bearings, causing damage to the transmission.

4. Install the recovery rigging using a safety chain system, see Recovery Rigging on page 2-21.

5. Make sure the recovered vehicle's parking brakes are released.

6. If you desire to use the recovered vehicles brakes, ensure that

the vehicles air system is connected to that of the recovery vehicle. Ensure that any air line that has been removed from a driver-controlled main differential lock is firmly capped to prevent loss of air pressure from the recovery vehicle if it is supplying air pressure. If you dont desire to use the recovered vehicles brakes, ensure that you cage the spring brakes before attempting to move the vehicle, see Driver Controlled Main Differential on page 2-18.

WARNING! Before towing a vehicle, test your air brakes to ensure that you have prop- erly connected and inspected the re- covery vehicles brake system. Fail- ure to do so could lead to a loss of vehicle control whichmay result in an accident involving death or personal injury.

7. Follow state/provincial and local laws that apply to vehicles in tow.

8. Do not tow vehicles at speeds in excess of 55 mph (90 km/h).

For additional information concerning heavy duty truck recovery, refer to the following Technology and Maintenance Council (TMC) literature.

Recovery Hitch Connection

Specially designed hitches are required to recover your vehicle. The recovery hitches attach to the frame.

Two hitch assemblies, made up of the following parts, are recommended for the proper recovery of your vehicle.

WARNING! Do not use parts from other trucks or materials from other sources to re- pair a hitch or to replace a missing hitch. The parts provided for recov- ery are made of high strength still specifically designed for vehicle re- covery. Failure to use the correct factory equipment may result in an accident involving death or personal injury.

VEHICLE RECOVERY AND SPRING BRAKES

Recovery Hitch Installation

Use the following procedure to install the Vehicle Recovery Hitches. See Recovery Hitch Assembly illustration for part identification.

1. Check square sockets behind lower bumper for obstructions, clear if necessary.

2. With lock pins removed, insert hitches through bumper and into the square hitch socket.

3. Align the hole in the tow hitch with the square hitch socket hole.

4. Insert the lock pin into the square hitch socket hole and through the hole in the tow hitch until the lock tab is within the square hitch socket.

5. Rotate the lock pin 90 degrees to secure the pin in place.

6. Remove the hitches and store all parts after recovering the vehicle.

Driver Controlled Main Differential

Follow these steps to lock a driver-controlled main differential.

WARNING! An open air line on the recovered vehicle will cause a leak in the air system of the recovery vehicle if both vehicles brake systems are connected. This could cause a loss of system air, which can cause the service brakes not to function, re- sulting in the sudden application of the spring brakes causing wheel lock-up, loss of control, or overtake by following vehicles. You could be in an accident involving death or personal injury. Ensure that any air line that has been removed from a driver-controlled main differential lock is firmly capped to prevent loss of air pressure from the recovery vehicle if it is supplying air pressure.

VEHICLE RECOVERY AND SPRING BRAKES

CAUTION Failure to lift the driving wheels off the ground or remove the driveline and axle shafts before towing the ve- hicle could seriously damage your vehicle. All lubricating and clutch ap- plication oil pressure is provided by an engine-driven pump, which does not work when the engine is stopped. When vehicles are towed either by wrecker or piggyback, lubricant in the top front of the drive axle will drain to the rear. This will leave the top com- ponents dry, resulting in friction that will seriously damage these compo- nents.

2. Cover open hubs when removing drive axle shafts.

CAUTION Water, dirt and other material can enter an open hub or axle. This can contaminate the axle fluid and cause possible damage to compo- nents. Ensure that the hubs are cov- ered with plastic whenever a drive axle shaft is removed.

3. For vehicles with driver-controlled main differential lock, install the caging bolt before removing the axle shafts for towing.

a. Remove the air line and firmly cap.

b. Remove the caging bolt from its storage hole.

c. Screw the caging bolt into the air line hole. When fully engaged, a 0.25-0.5 in. (6.35-12.7 mm) space will remain between the air cylinder and the bolt head.

This action will lock the differential by pushing a piston into a lock position.

CAUTION Failure to install the caging bolt when towing vehicles with driver-control main differential lock can result in damage by failing to lock internal components in position.

WARNING! Ensure there are no open air lines on the recovered vehicle if the re- covery vehicle and recovered vehicle brake systems are connected. An open air line on the recovered vehi- cle will cause a leak in the air brake system of the recovery vehicle pos- sibly causing death, personal injury, equipment or property damage.

VEHICLE RECOVERY AND SPRING BRAKES

CAUTION A recovered vehicle will have no op- erational brake system. Additionally, the rear axle spring brakes will prob- ably be applied.

If you desire to use the recovered vehicles brakes, ensure that the vehicles air system is connected to that of the recovery vehicle. Also ensure that any air line that has been removed from a driver-controlled main differential lock is firmly capped to prevent loss of air pressure from the recovery vehicle.

If you dont desire to use the recovered vehicles brakes, ensure that you cage the spring brakes before attempting to move the vehicle.

4. Install recovery hitches and rigging.

CAUTION Connect recovery rigging only to hitches intended for that purpose. Do not attach to bumpers or brack- ets. Connections to other structural parts could damage the vehicle.

Recovery Hitch Capacities

The maximum rated loads for vehicle recovery varies depending on the direction or angle of pull. These capacities are listed in the table below and are for the two hitches working together, simultaneously.

Hitch Capacities

DIRECTION OF PULL

MAXIMUM CAPACITY

(Lb) * Directly Forward 80,000

Directly Vertical or Horizontally to the Side

14,600

DIRECTION OF PULL

MAXIMUM CAPACITY

(Lb) * 45 in any Direction 20,000

* Both hitches pulled simultaneously.

CAUTION Recovery pull maximums assume the tow rigging evenly distributes the load between both recovery hitches. See examples in Recovery Rigging on page 2-21 for details. Serious damage to the vehicle may occur if rigging is not connected properly.

CAUTION When recovering ditched or bogged vehicles, stay well below Maximum Capacities. Even at loads below maximum, the physical strain of re- covering a vehicle could damage axles, suspensions, fifth wheels, etc.

VEHICLE RECOVERY AND SPRING BRAKES

Recovery Rigging

To connect to the vehicle, follow the suggested rigging methods below.

Use a double chain or cable setup that distributes the load equally to both hitches.

Never loop a single chain or cable through both hitches.

Use a spreader or equalizer bar to distribute the load on both hitches.

If no spreader bar is available, connect the main tow chain or cable no closer than 6 ft. from the vehicle.

1. Spreader Bar or Equalizer

2. Connection to bumper via tow pin or hook

3. 2 or 3 piece tow device

VEHICLE RECOVERY AND SPRING BRAKES

Returning Vehicle to Service

You will have to add lubricant to prevent damage after your vehicle has been towed.

1. Into the pinion cage, add 1 pint (.47 liter) of lubricant or into the interaxle differential, add 2 pints (.94 liter) of approved lubricant.

2. After adding the specified type and amount of lubricant, drive the vehicle. It should be unloaded. Drive 1 to 2 miles (1.5 to 3 km) at a speed lower than 25 mph (40 km/h). This will thoroughly circulate the lubricant through the assembly.

Spring BrakesManual Release

Recovering a vehicle requires that you release the parking brakes. There may be times when there is not enough air pressure to release the parking brakes. In such cases, the parking brakes (or Spring Brakes) can be manually released.

WARNING! Do not drive vehicle with malfunc- tioning brakes. If one of the brake circuits should become inoperative, braking distances will increase sub- stantially and handling characteris- tics while braking will be affected. You could lose control of your vehi- cle or cause an accident. Have it towed to the nearest dealer or qual- ified repair facility for repair. Failure to comply may result in death, per- sonal injury, equipment or property damage.

The brakes can be released in this manner should the pressure in the air system not be enough to release them. This may occur in instances where the engine's air compressor is not able to get the system up to operating pressure.

WARNING! Do not disassemble a spring brake chamber. These chambers con- tain a powerful spring that is com- pressed. Sudden release of this spring may result in death or per- sonal injury.

2-22 Y53-6076-1B1 (03/17)

VEHICLE RECOVERY AND SPRING BRAKES

WARNING! Do not operate a vehicle when the spring brakes have been manually released. Driving a vehicle after its spring brakes are manually released is extremely dangerous. The brakes may not function. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING! Always secure the vehicle with wheel chocks, chains, or other safe means to prevent rolling be- fore manually releasing the spring brakes. Releasing the spring brakes on an unsecured vehicle could lead to an accident. The vehicle could roll, which may result in death, per- sonal injury, equipment or property damage.

To move a vehicle immobilized by the spring brakes due to loss of air

pressure in the brake system, perform the following procedure:

1. Remove the cap from the spring chamber.

2. Remove the release stud assembly from the side pocket, and remove the release nut and washer from the release stud.

3. Slide out the release stud.

4. Insert the release stud through the opening in the spring chamber where the cap was removed. Insert it into the pressure plate. Turn the release stud 1/4 turn clockwise in the pressure plate. This secures the cross pin into the cross pin area of the pressure plate and locks it into the manual release position.

5. Assemble the release stud washer and nut on the release stud.

VEHICLE RECOVERY AND SPRING BRAKES

6. With a wrench, turn the release stud assembly nut until the compression spring is 90-95 percent caged. While doing this, check to make sure the push rod (adapter push rod or service push rod) is retracting. Do not over-torque the release stud assembly. (S-Cam type maximum: 50 lb-ft, Wedge type maximum: 30 lb-ft). The spring brake is now mechanically released.

Sand, Mud, Snow and Ice

If the vehicle gets stuck in sand, mud, snow, or ice:

Move the gearshift lever or selector from First to Reverse.

Apply light pressure on the accelerator pedal while the transmission is in gear.

Remove your foot from the accelerator while shifting.

Do not race the engine.

For best traction and safety, avoid spinning the wheels.

WARNING! Do not spin the wheels faster than 35 mph (55 km/h). Spinning a tire at speedometer readings faster than 35mph (55 km/h) can be dangerous. Tires can explode from spinning too fast. Under some conditions, a tire may be spinning at a speed twice that shown on the speedometer. Any resulting tire explosion could cause death or personal injury to a bystander or passenger, as well as extensive vehicle damage: includ- ing tire, transmission and/or rear axle malfunction.

Comply with the following instructions to avoid transmission damage:

Always start vehicle in motion with the shift lever in first gear.

2-24 Y53-6076-1B1 (03/17)

2

VEHICLE RECOVERY AND SPRING BRAKES

Be sure that transmission is fully engaged in gear before releasing the clutch pedal (manual only).

Do not shift into reverse while the vehicle is moving.

If the vehicle needs to be recovered from being stuck, do not permit the vehicle to be towed for long distances without removing the driveshaft.

Tire Chains

If you need tire chains, install them on both sides of the driving axle.

CAUTION Chains on the tires of only one tan- dem axle can damage the driveline U-joints and the interaxle differen- tial. Repairs could be costly and time-consuming. Failure to comply may result in equipment damage.

Towing the Vehicle

Towing the vehicle should be done by either an authorized dealer or a commercial vehicle towing service. The dealer or commercial towing service will have the necessary equipment to safely tow the vehicle and should be able to make arrangements to limit any damage to the vehicle. The towing service and the dealer should be aware of towing regulations and safety precautions.

The towing service will ensure that the following precautions are taken:

Use of a safety chain system.

Abide by all local towing regulations.

Ensure that the towing device does not contact any surfaces that could be damaged while in transit.

If towing from the front, ensure that the rear axles are prepared for towing.

If towing from the rear, ensure that all body components such as roof, side and chassis fairings are secured properly to avoid damage while in transit.

WARNING! Secure the roof, side and chassis fairings while towing from the rear. An unsecured fairing may come off of the vehicle during transit. Failure to secure the fairings while towing may cause an injury accident result- ing in death or personal injury.

Check Messages

Check messages are provided to give the operator additional information regarding systems that require attention due to a system malfunction and/or operating conditions that may hinder safe and proper performance for the vehicle. Some messages can be managed by the operator while others may require an authorized dealer repair.

1. Speedometer

The Speedometer indicates the vehicle speed in miles per hour (mph) and in kilometers per hour (km/h). The Speedometer cluster also includes several warning and indicator lamps (see Warning Symbols on page 3-15).

2. Tachometer

The Tachometer measures the engine speed in revolutions per minute (RPM).

The RPM Detail is also available as a viewable screen in the instrumentation cluster. Viewing the RPM detail is accomplished by using the MCS dial to rotate to the [VIRTUAL GAUGES].

The tachometer is a useful gauge when attempting to drive efficiently. It will let you match driving speed and gear selection to the operating range of your engine. If the engine speed gets too high, you can select a higher gear to lower the RPM's. If the engine speed drops too low, you can select a lower gear to raise the RPM's. (Refer to Driving Tips and Techniques on page 4-44 for further instructions on driving techniques and using the tachometer.) To avoid engine damage, do not let the pointer exceed maximum governed speed. (See your Engine

(03/17) Y53-6076-1B1 3-9

INSTRUMENT PANEL

Operation and Maintenance Manual for RPM recommendations.)

3. Engine, Coolant Temperature

The water temperature gauge shows the temperature of the engine coolant. Under normal operating conditions the water temperature gauge should register between 165 and 205F (74 and 90C). Under certain conditions, somewhat higher temperatures may be acceptable. But the maximum allowable temperature is 210F (99C), except for certain special engines. Check your engine manual to be sure.

Please refer to Engine is Overheating on page 2-5 for instructions on what to do if the engine is overheating.

4. Fuel Level, Primary

The Primary Fuel gauge indicates the total (approximate) amount of fuel in the fuel tank. In addition to indicating empty and full, the gauge(s) also indicate the fuel level in graduated increments. When the fuel level for the tank is below 1/4 full, a red warning light in the gauge will come on.

Primary

Secondary

INSTRUMENT PANEL

NOTE For Export vehicles, the fuel gauges will not state: ULTRA LOWSULFUR DIESEL FUEL ONLY.

NOTE This vehicle may be manufactured with different fuel systems and differ- ent draw tube locations. Because of this and the amount of road crown, it is recommended that you do not operate your vehicle with less than one-quarter of your trucks fuel ca- pacity. Allowing the fuel level to go below one-quarter of capacity could result in the lack of fuel to keep the engine running. In addition, you will want to keep the fuel tanks at least half-full to reduce condensation of moisture in the tanks. This moisture can damage the engine.

WARNING! Do not carry fuel containers or any container used to store combustible liquids. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING! Do not remove a fuel tank cap near an open flame. Fuel vapors may be hot and combustible and can cause an explosion or fire. Failure to com- ply may result in death, personal in- jury, equipment or property damage.

Refer to Refueling on page 4-51 for more information.

5. Engine, Oil Pressure

It is important to maintain oil pressure within acceptable limits. If oil pressure drops below the minimum psi a red warning light in the gauge will turn on, the Stop Engine light will come on and an audible alarm tone will sound.

For further information on engine oil and normal operating pressures, see the Engine Operation and Maintenance Manual.

CAUTION Operating your vehicle with insuffi- cient oil pressure will cause serious engine damage.

If the oil pressure fails to rise within 10 seconds after the engine starts, stop the engine and determine the cause.

(03/17) Y53-6076-1B1 3-11

3

INSTRUMENT PANEL

Check the engine manufacturer's manual for the correct oil pressure ranges for your vehicle's engine.

If the oil pressure suddenly drops, or the audible alarm and engine oil pressure warning light come on while driving, please refer to Engine Oil Pressure Lamp Turns On on page 2-4 regarding what to do if oil pressure is insufficient.

6. Diesel Exhaust Fluid (DEF)

The diesel exhaust fluid gauge shows the approximate amount of DEF fluid in the DEF tank. Besides empty and full, the gauge also indicates 1/4, 1/2, and 3/4 of total capacity. DEF fluid is required to meet certain emission requirements. Do not allow your DEF tank to remain empty. Please refer to your emission supplemental manual for more details about DEF fluid.

CAUTION Use Diesel Exhaust Fluid only. Fail- ure to do so may damage compo- nents of the Diesel Particulate Filter (DPF).

7 and 8. Primary and Secondary Air Pressure

Primary Air Pressure

Secondary Air Pressure

The Primary Air Pressure gauge indicates pressure in the rear braking system. The Secondary gauge indicates pressure in the front braking system. Each gauge indicates the amount of air pressure in each system in pounds per square inch (psi).

On vehicles equipped with metric air pressure gauges, the gauge face plate includes a kPa (major) scale and psi (minor) scale.

3-12 Y53-6076-1B1 (03/17)

3

INSTRUMENT PANEL

Please refer to Low Air Alarm Turns On on page 2-3 for instructions on what to do if the air system becomes inoperative.

NOTE Be sure the air pressure registers more than 100 psi (690 kPa) in both service systems before you move the vehicle.

NOTE If the pressure in either or both cir- cuits falls below 65 psi (448 kPa), a red warning light in the gauge will turn on and an audible alarm tone will sound when the engine is run- ning.

WARNING! If the air pressure falls below 60 psi (414 kPa), the spring brakes may stop the vehicle abruptly which could cause an accident resulting in death or personal injury. Observe the red warning lamps on the gauges. If one comes on, do not continue to drive the vehicle until it has been properly repaired or serviced. If the light and alarm do not turn off at start-up, do not try to drive the vehicle until the problem is found and fixed.

WARNING! The air pressure warning light and the audible alarm tone indicate a dangerous situation: there is not enough air pressure in the air tanks for repeated braking and the brake system has failed. Without the use of your service brakes your spring brakes could suddenly apply caus- ing a wheel lock-up, loss of control, or over-take by following vehicles. This may cause an accident result- ing in death or personal injury. Bring the vehicle to a safe stop right away, while you still have control of the vehicle.

WARNING SYMBOLS

WARNING SYMBOLS

Guide to the Warning Symbols

The warning lights and audible alarm may indicate a system malfunction. Check the lights frequently, and respond properly as soon as you see one go on. These lights could save you from a serious accident.

When multiple warning icons are shown on the instrument cluster, they will appear at first and then minimize. When minimized they will be represented in the active warnings area of the display (see Warning Light/Indicator Symbols on page 3-16 for details). A triangle represents a warning registered and a diamond represents a check message.

WARNING! Do not ignore a warning light or audible alarm. These signals tell you something is wrong with your vehicle. It could be a failure in an im- portant system, such as the brakes, which could lead to an accident causing death or injury. Have the appropriate system checked imme- diately.

Check messages are provided to give the operator additional information regarding systems that require attention due to a system malfunction and/or operating conditions that may hinder safe and proper performance for the vehicle. The system will emit a chime to alert the operator that a message is appearing on the cluster. Some messages can be managed by the operator while others may require an authorized dealer repair.

Calculates the drivers intended path of travel from wheel speed and steering angle sensors, then compares calculations to the actual direction of travel. The system uses individual wheel brakes to re-adjust the path of the vehicle.

Illuminates during the power-on self-test when the ignition is turned ON. It turns off after a few seconds if no system problems are detected. If an ESC problem is detected, the ESC warning lamp will turn on and stay on.

Illuminates when the ESC system is regulating individual wheel brakes to correct the vehicles direction of travel.

2. Axle, Traction Control (ATC or Automatic Traction Control)

Watches vehicles wheel speeds to detect slippage and may reduce engine power, or apply vehicle brakes, to help increase traction.

Illuminates during the power-on self-test when the ignition is turned ON. It turns off after a few seconds if no system problems are detected. If an ATC problem is detected, the ATC warning lamp will turn on and stay on.

Illuminates when the ATC is regulating wheel spin and turns off after the traction control event has ended.

Flashes continuously when the ATC/Deep Snow & Mud switch is turned on, indicating that this feature is active.

3. Brakes, Anti-Lock Brake System (ABS)

Illuminates during the Instrumentation System Self-Test. Have the ABS system checked by an authorized dealer if the ABS Warning Lamp stays on for more than 3 seconds.

STANDARD GAUGES

Introduction

On the pages that follow you will find descriptions of some of the gauges on your instrument panel. For more information about using them in driving, see Starting and Operating the Vehicle Also check the Index under the name of the gauge or function you want to know more about.

WARNING! Do not ignore a warning light or audible alarm. These signals tell you something is wrong with your vehicle. It could be a failure in an important system, such as the brakes, which could lead to an acci- dent. Have the appropriate system checked immediately.

Some gauges will display a red LED warning light, with some accompanied

by an audible alarm, whenever the limits of the function being displayed are exceeded.

Speedometer

The speedometer indicates the vehicle speed in miles per hour (mph) and in kilometers per hour (km/h). The speedometer also includes an odometer, trip meter, and trip reset button.

(03/17) Y53-6076-1B1 3-29

STANDARD GAUGES

Odometer / Trip Meter

The LCD display in the lower part of the speedometer contains the odometer and trip meter.

The odometer displays the total distance your vehicle has traveled. It will display in miles on an English speedometer or in kilometers on a metric speedometer. The maximum distance that can be shown on the odometer is 1 999 999 before it rolls over to zero.

The trip odometer displays how far the vehicle has gone on a particular trip. The trip odometer will display in miles on an English speedometer or in kilometers on a metric speedometer, in one tenth divisions. The maximum distance that can be shown on the trip

odometer is 9999.9 before it rolls over to zero.

To reset the trip odometer, press and hold the trip reset button on the speedometer. The numbers will reset to 0 and begin to count new miles/km traveled. This also resets the trip values in the Driver Information Display.

The trip reset button also toggles all displays between English and Metric.

NOTE The Odometer/Trip Meter comes on when the door is opened or the key is in the accessory or ignition position. The Odometer/Trip Meter will remain on for 3 seconds after the door is closed or the ignition switch is turned off. This allows driver and service personnel to read the odometer without ignition switch being turned on.

Tachometer

Your tachometer measures the engine speed in revolutions- per-minute (RPM). The tachometer also includes an engine hour meter and outside air temperature display.

3-30 Y53-6076-1B1 (03/17)

STANDARD GAUGES

Engine Hours / Outside Air Temperature

The LCD display in the lower part of the tachometer contains the engine hour meter and the outside air temperature display.

The engine hour meter will display the total number of hours the engine has been running. The maximum hours that can be shown are 99999.9 before the meter rolls over to zero.

The outside air temperature (OAT) will display the temperature outside the vehicle. The temperature can be displayed from -40 to 158 in Fahrenheit or -40 to 70 Celsius. The display will also alert the driver when the outside temperate approaches freezing (32F or 0C) by displaying

a snowflake symbol. The symbol will turn on when the temperature drops below 34F or 11C and flash for the first 3 seconds, then stay on until the temperature goes above 37F or 28C

The temperature can display using Standard or Metric units. Press the trip reset button on the Speedometer 4 times within 4 seconds. This will also change the units shown by the Driver Information Display.

NOTE The OAT will come on when the door is open and the key switch is in the accessory or ignition position. The OAT display will turn off when the ignition switch is turned off.

NOTE The OAT uses a sensor (located at the bottom of the drivers side mir- ror assembly) to measure outside air temperature only. It is not capable of displaying the temperature of the road surface on either the tempera- ture display or the snowflake icon.

NOTE The effects of direct sunlight, or the use of mirror heat, will increase the outside air temperature displayed while the vehicle is stationary.

STANDARD GAUGES

Fuel Gauge

WARNING! Do not remove a fuel tank cap near an open flame. Hot fuel vapors are combustible and can cause an ex- plosion or fire resulting in injury or death.

CAUTION Use Ultra Low Sulfur Diesel fuel only. Failure to do so may damage components of the Diesel Particu- late Filter (DPF).

The fuel gauge shows the approximate amount of fuel in the fuel tanks. Besides empty and full, the gauge also indicates 1/4, 1/2, and 3/4 of total capacity. You will want to keep your fuel tanks at least half full to reduce condensation of moisture in the tanks. This moisture can damage your engine.

Primary (Secondary) Air Pressure Gauge (Air Reservoir)

The air pressure gauge indicates the amount of air pressure in the brake system in pounds per square inch (psi).

The primary gauge shows rear reservoir air pressure.

The secondary gauge shows pressure in the front reservoir.

3-32 Y53-6076-1B1 (03/17)

STANDARD GAUGES

Ensure the air pressure registers more than 100 psi in both service systems before you move the vehicle. If the pressure in either circuit is too low for normal brake operation, the warning light will glow and the audible alarm will sound.

WARNING! The air pressure warning light and the audible alarm indicate a danger- ous situation. There is not enough air pressure in the reservoirs for re- peated braking and the brake sys- tem has failed. If air pressure falls below 60 psi (414 kPa) the spring brakes could suddenly apply, caus- ing a wheel lockup, loss of control, or your vehicle to be overtaken by following vehicles. You could be in an accident and severely injured. If these alarms come on while you are driving, bring your vehicle to a safe stop right away. If the light and alarm do not turn off at start-up, do not try to drive the vehicle until the problem is found and fixed.

Diesel Exhaust Fluid (DEF) Gauge

The diesel exhaust fluid gauge shows the approximate amount of DEF fluid in the DEF tank. Besides empty and full, the gauge also indicates 1/4, 1/2, and 3/4 of total capacity. DEF fluid is required to meet certain emission requirements. Maintain an adequate amount of diesel exhaust fluid at all times, as provided in the aftertreatment system operator manual. Please refer to the aftertreatment operator manual for more details about DEF fluid.

Windshield Wipers/Washer

Your vehicle is equipped with a two-speed, intermittent windshield wiper system. The windshield wiper system is integrated with the exterior lights so that the low beam headlights will turn on when the windshield wipers turn on. To override this function, turn the headlights on and then off again and the low beams will turn off. A seven-position rotary wiper switch (located on the turn signal lever) operates the windshield wipers and washer. Rotate the end of the turn signal lever to change the wiper mode.

NOTE The ignition key must be turned to ON or ACC for the wiper/washer switches to operate.

Wiper/Washer

The first position after OFF is the intermittent #1 cycle. The next positions are intermittent #2, #3, and #4. The last two positions are wiper low speed and wiper high speed.

To Wash The Windshield

Push the rotary wash/wipe knob in (towards steering column), hold for more than 0.8 seconds and then release. Hold the knob in to extend the washing cycle. After the lever is released, the wipers will shut off automatically or resume the wipers setting speed.

To activate the wipers for one swipe without activating the washer (mist function), push the turn signal lever in (towards the steering column) and release in less than 0.5 seconds. The wipers will perform a single swipe and then resume the wipers setting speed.

WARNING! Clean blades regularly with a damp cloth to remove road film and wax build-up. Do not drive with worn or dirty wiper blades. They can reduce visibility, making driving hazardous which may lead to an injury accident resulting in death or personal injury.

CAUTION Do not use antifreeze or engine coolant in the windshield washer reservoir - damage to seals and other components will result.

Introduction

WARNING! Do not drive with visibility reduced by fog, condensation, or frost on the windshield. Your view may be ob- scured, which may result in death, personal injury, equipment or prop- erty damage. For clear visibility and safe driving it is extremely impor- tant for you to follow the instructions pertaining to the function and use of the ventilation/heating and defog- ging/defrosting system. If in doubt, consult your dealer. Maximum heat- ing output and fast defrosting can be obtained only after the engine has reached operating temperature.

WARNING! Exhaust fumes from the engine con- tain carbon monoxide, a colorless and odorless gas. Do not breathe the engine exhaust gas. A poorly maintained, damaged or corroded exhaust system can allow carbon monoxide to enter the cab. Entry of carbon monoxide into the cab is also possible from other vehicles nearby. Failure to properly maintain your ve- hicle could cause carbon monoxide to enter the cab, resulting in death or personal injury.

WARNING! Never idle your vehicle for prolonged periods of time if you sense that ex- haust fumes are entering the cab. Investigate the cause of the fumes and correct it as soon as possible. If the vehicle must be driven under these conditions, drive only with the windows open. Failure to repair the source of the exhaust fumes may re- sult in death, personal injury, equip- ment or property damage.

HEATING AND AIR CONDITIONING

NOTE Keep the engine exhaust system and the vehicles cab ventilation system properly maintained. It is recommended that the vehicles ex- haust system and cab be inspected:

By a competent technician every 15,000 miles

Whenever a change is noticed in the sound of the exhaust system

Whenever the exhaust system, underbody, or cab is damaged

NOTE To allow for proper operation of the vehicle ventilation system, keep the inlet grille at the base of the wind- shield clear of snow, ice, leaves and other obstructions at all times.

CAUTION Do not stay in the vehicle with the engine running or idling for more than 10 minutes with the vehicle's Heater and A/C ventilation system in RECIRC or at LOW FAN SPEED. Even with the ventilation system on, running the engine while parked or stopped for prolonged periods of time is not recommended.

NOTE When idling for short periods of time:

Set the heating or cooling system to Heat or A/C

Set the fan to Medium or High speed

Set the controls to FRESH AIR

NOTE If you are required to idle your ve- hicle for long periods of time, install an auxiliary heater or automatic idle control. These auxiliary devices can reduce fuel consumption and save you money.

NOTE If you are parked next to idling ve- hicles, move your vehicle or do not stay in your vehicle for prolonged pe- riods of time.

Using this button does not allow this control unit to control sleeper blower speed or sleeper temperature. It only turns the sleeper heating and air conditioning unit on or off.

Tips for Efficient Cooling

An air conditioner can reduce fog build up on the windshield by setting it to the defrost or the floor/defrost air selection. To increase the effectiveness of the air conditioner, use the A/C button in the ON position, increase the air temperature setting and/or increase the fan speed.

If the cabin becomes humid or damp, use the air conditioner with the fan on, with fresh air (not in recirculate air mode) and the A/C in the ON position to dry the cabin air.

In situations where more cooling of the cab is required, make sure the system is in the recirculation mode. This setting will be more effective than using fresh air.

HEATING AND AIR CONDITIONING

How To Use The System

The engine must be running for the heater and air conditioner to generate hot and cold air.

To Cool

Push the Fresh Air/Recirculation Switch to the Fresh Air mode (Blue indicator light off). Manually setting the system to recirculate air will increase the effectiveness and uses the least amount of fuel.

Turn ON the Fan Control Dial to the desired fan speed.

Turn Temperature Dial to Desired Setting.

Turn the Air Flow Control Dial to Dash Vents.

If the outside air is not cold enough to cool the cab, press to engage the compressor which will deliver colder air.

For more cooling effect, you may need to press the switch back to recirculation mode.

To Heat

Turn the Fan Control Dial ON to the desired fan speed.

Turn the Air Flow Control Dial to Floor Vents.

Adjust the Temperature Control Dial clockwise until the air temperature feels comfortable.

Using this function in "manual" mode will provide the maximum heating performance.

To Dehumidify

Push the Fresh Air/Recirculate Switch to the Fresh Air mode (Blue indicator light off).

Turn ON the Air Conditioning Switch (Blue indicator light on).

HEATING AND AIR CONDITIONING

Turn ON the Fan Control Dial to the desired fan speed.

Adjust the Temperature Control Dial until the air temperature feels comfortable.

The air conditioner removes moisture from the air while the heater heats the air.

To Defog and Defrost theWindshield

Turn the Fan Control Dial clockwise to the highest fan speed.

Turn the Air Flow Control Dial to Defrost Vents.

Fresh air and air conditioning are automatically turned ON.

Adjust the Temperature Control Dial clockwise to full heat.

CAUTION During extreme cold weather, do not blow hot defroster air onto cold wind- shields. This could crack the glass. Turn the Air Flow Control Dial to De- frost and adjust the fan speed ac- cordingly while the engine warms. If the engine is already warm, move the Temperature Control Dial to cool, then gradually increase the temper- ature when you see that the wind- shield is starting to warm up. Failure to comply may result in equipment damage.

Sleeper Heater - A/C Controls (optional)

A separate switch on the dash HVAC unit will send power to the bunk or sleeper control unit The button on the cab HVAC unit must be pressed and in the on mode to use the sleeper controls. The sleeper control unit has three controls:

1. Air speed control

2. Air conditioner compressor on/off

3. Air temperature control

Unlike the cabin air temperature controls, the sleeper temperature control will alter the air temperature

based on the knob setting. The Temperature Control is not keyed to specific temperatures. Turning counterclockwise means cooler than it is now. Clockwise means warmer than it is now. Once the desired temperature is reached, the system will maintain it automatically.

NOTE The sensor is located on the sleeper heater - A/C control panel and mea- sures the sleeper air temperature at the panel. There will be a time delay between Temperature Control adjustment and sleeper air tempera- ture change. Also, be careful of any heat source which could affect the air temperature by the sensor. Avoid hanging items (e.g. shirt, jacket, etc.) which could block the air flow to the sensor.

STARTING & OPERATING

STARTING & OPERATING

Introduction

Since each vehicle is custom-equipped, all engine operation instructions in this manual are general. You will want to consult the manual for your engine to find out details about your specific engines needs. You may need to use a slightly different procedure from the one outlined here.

The following instructions are for both normal-temperature starting and cold-weather starting.

Normal Weather

When the outside temperature is above 50 F (10 C), you can use the following procedure.

1. Set the parking brake.

2. Put your main transmission in Neutral.

3. Disengage (depress) the clutch (with manual transmission).

4. Turn the key switch to ON.

CAUTION Never operate the starter motor while the engine is running. The starter and flywheel gears could clash or jam, severely damaging them.

NOTE Some starters are equipped with overcrank protection. Check the Engine Operation and Maintenance Manual for details.

5. Turn the ignition key to the START position. If the engine does not start within 30 seconds, release the ignition switch. To avoid overtaxing the starter motor or the batteries, dont use the starter for more than 30 seconds. Let the starter motor cool and the batteries recover for two minutes before trying again. If the engine still wont start after a couple of tries, check the fuel lines for possible fuel starvation or air leaks. Starting failure may mean fuel isnt reaching the injectors.

6. As soon as the engine starts, begin to watch the oil pressure gauge. Check your engine manufacturers

(03/17) Y53-6076-1B1 4-5

4

STARTING & OPERATING

manual for the right pressure for your engine. If the oil pressure doesnt rise within a few seconds, stop the engine. Find out what is wrong before restarting the engine.

7. Slowly engage (release) the clutch after the engine has started.

8. Wait for the oil pressure gauge to reach normal operating pressure before operating the vehicle or idling faster than 1000 rpm.

Cold Weather

In cold weather, fast engine starting helps relieve the loads on the electrical system and cranking motor. Using the special cold starting equipment will help starting. If you follow a few simple guidelines, you will extend the service life of your engine.

Keep the electrical system in top condition.

Use the best quality fuel of the recommended grade.

Use recommended engine lubricating oil.

Fully depress the accelerator pedal after engaging the starter.

For manual transmissions and auxiliary transmissions, leave the transmission in neutral and allow the transmission lubricating oil to warm up (approximately 3-5 minutes) before operating vehicle.

Engine Block Heater (Option)

To preheat the engine before starting, plug the optional engine block heater into a properly grounded AC electrical source. Do not start the engine with the heater plugged in.

WARNING! Engine block heaters can cause fires which may result in death, in- jury and/or property damage if not properly maintained and operated. Regularly inspect the engine block heater wiring and connector for damaged or frayed wires. Do not use the heater if there are any signs of problems. Contact your autho- rized dealer or the manufacturer of the heater if you are in need of re- pairs or information.

4-6 Y53-6076-1B1 (03/17)

4

STARTING & OPERATING

CAUTION Always unplug heater before starting the engine. Damage to the cooling system could occur if the heater is not turned OFF (unplugged).

Depending on engine make, when the temperature falls below -10 F (-24 C), the block heater is required.

Use a solution of half ethylene glycol antifreeze and half water for best heater performance. Do not exceed 65 percent concentration of antifreeze, as a shortened heater life will result. See Cooling System Maintenance on page 4-56, for more information.

After servicing the cooling system, operate the vehicle for a day or two before using the heater. Trapped air inside the engine needs time to escape.

Engine Warm-up Engine

The purpose of engine warm-up is to allow oil film to be established between pistons and liners, shafts and bearings while your engine gradually reaches operating temperature.

Warm-up Procedure

1. After youve started your engine, idle it at approximately 600 RPM while you check:

a. oil pressure

b. air pressure

c. alternator output

2. After a few minutes of idling at 600 RPM, increase your idle speed to 900 or 1000 RPM. Continue your warm-up. This procedure allows oil to warm and flow freely while pistons, liners, shafts, and bearings expand

slowly and evenly. In extremely cold temperatures, you may have to increase idle speed.

NOTE In colder climates where the tem- perature is often below freezing, the warm-up for turbocharged en- gines is especially important. Chilled external oil lines leading to the tur- bocharger will slow the oil flow until the oil warms, reducing oil available for the bearings. Watch the engine oil temperature or pressure gauge for a warming trend before increas- ing engine idle speed (RPM).

3. Continue the engine warm-up until the coolant temperature reaches at least 130 F (54 C). At this temperature, you can use partial throttle. Wait until the coolant temperature is at least 160 F (71 C) before operating at full throttle.

(03/17) Y53-6076-1B1 4-7

4

STARTING & OPERATING

WARNING! Exhaust fumes from the engine contain carbon monoxide, a color- less and odorless gas. A poorly maintained, damaged, or corroded exhaust system can allow car- bon monoxide to enter the cab or sleeper. Failure to properly main- tain your vehicle could cause car- bon monoxide to enter the cab and cause death or personal injury.

WARNING! Never idle your vehicle for prolonged periods of time if you sense that ex- haust fumes are entering the cab. Investigate the cause of the fumes and correct it as soon as possible. If the vehicle must be driven under these conditions, drive only with the windows slightly open. Failure to re- pair the source of the exhaust fumes may lead to death or personal injury.

CAUTION The use of a winterfront can result in excessive engine coolant, oil, and charge air (intake) temperatures, which can lead to overheating and possible engine damage. If you must use a winterfront:

Refer to the Engine Operation and Maintenance Manual for operating restrictions and recommendations.

Use only a winterfront available from your dealer that is compatible with an EPA-compliant engine cooling system. These winterfronts are specifically designed for use with new grill snap patterns.

NOTE Keep the engine exhaust system and the vehicles cab/sleeper venti- lation system properly maintained. It is recommended that the vehicles exhaust system and cab/sleeper be inspected:

By a competent technician every 15,000 miles

Whenever a change is noticed in the sound of the exhaust system

Whenever the exhaust system, underbody, cab or sleeper is damaged

4-8 Y53-6076-1B1 (03/17)

4

STARTING & OPERATING

NOTE Do not stay in the vehicle with

the engine running or idling for more than 10 minutes with the vehicles Heater and A/C ventilation system in RECIRC or at LOW FAN SPEED. Even with the ventilation system On, running the engine while parked or stopped for prolonged periods of time is not recommended.

If other vehicles are parked next to you idling, move your vehicle or do not stay in your vehicle for prolonged periods of time.

Idling the Engine

Under most circumstances, idling your engine for long periods merely wastes fuel. In severe arctic weather conditions, however, you may need longer idling to be sure all parts of your engine are fully lubricated.

WARNING! To reduce the chance of death or personal injury and/or vehicle dam- age from overheated engines, which can result in a fire, never leave the engine idling without an alert driver present. If the engine should over- heat, as indicated by the engine coolant temperature light, immedi- ate action is required to correct the condition. Continued unattended operation of the engine, even for a short time, may result in serious engine damage or a fire.

CAUTION Do not allow your engine to idle, at low rpm's (400600 rpm), longer than five minutes. Long peri- ods of idling after the engine has reached operating temperatures can decrease engine temperature and cause gummed piston rings, clogged injectors, and possible en- gine damage from lack of lubrica- tion. The normal torsional vibrations generated can also cause transmis- sion wear.

STARTING & OPERATING

Transmission

In cold weather (below 32 F (0 C), you may find shifting sluggish when you first start up. Transmission warm-up is especially important at this time, but it is always a good idea to warm-up your transmission before starting out on the road. To warm-up the transmission, follow these procedures.

To warm-up the transmission lubricating oil during engine warm-up, with a single transmission (manual and automatic):

1. Put the transmission in Neutral.

2. Release the clutch pedal (manual only) and operate the transmission in neutral for 3 to 5 minutes prior to operating the transmission in either forward or reverse range.

3. If you have a two-transmission combination:

a. Put the main transmission in gear.

b. Put the auxiliary transmission in Neutral. This will allow the transmission countershaft to turn, agitating the oil and warming it.

OPERATING THE ENGINE

OPERATING THE ENGINE

Stationary PTO Operation

The cruise control buttons for this vehicle may be used to control the engine rpm when the vehicle is stationary and the operator wants to use the PTO on the engine. Use the cruise control options in the same manner as with the vehicle in motion, but instead of setting vehicle speed, the engine speed (RPM) is set instead.

Setting Idle Speed

1. Ensure parking brakes are applied.

2. Ensure transmission is in Neutral.

3. Engage PTO per the manufacturer's operating instructions.

4. Move the ON/OFF switch to the "ON" position.

5. Toggle the SET/RESUME switch to obtain the desired engine rpm.

Cancelling Cruise Control

You can cancel cruise control in any of these ways:

Tap the brake pedal.

Tap the clutch pedal.

Move the ON/OFF switch to the "OFF" position.

Engine Fan Control

The engine fan can be turned ON using a switch that is mounted on the accessory switch panel. This lets you set the fan to manual or automatic operation.

With the ignition key turned ON and the fan switch in the MANUAL position, the engine fan will be ON regardless of engine temperature.

With the engine fan switch in the AUTO position, the engine fan will automatically turn ON when the engine computer sends a signal requiring the engine fan to be on.

(03/17) Y53-6076-1B1 4-11

OPERATING THE ENGINE

WARNING! Do not work on or near the fan with the engine running. Anyone near the engine fan when it turns on could be injured. If it is set at MANUAL, the fan will turn on any time the ignition key switch is turned to the ON posi- tion. In AUTO, it could engage sud- denly without warning. Before turn- ing on the ignition or switching from AUTO toMANUAL, be sure no work- ers are near the fan.

CAUTION The fan or equipment near it could be damaged if the fan turns on sud- denly when you do not expect it. Keep all tools and equipment away from the fan.

NOTE Do not operate the engine fan in the MANUAL position for extended periods of time. The fan hub was designed for intermittent operation. Sustained operation will shorten the fan hub's service life as well as re- duce fuel economy.

Winterfronts

A winterfront or other air flow restriction device may be mounted in front of the radiator to increase cab heater temperature in cold climates.

CAUTION A winterfront should only be used at temperatures below 40F (4C). Use of a winterfront above 40F (4C) can decrease life of cool- ing module components. Remove winterfront as soon as the ambi- ent temp reaches 41F (5C). The use of a winterfront above 40F (4C) can result in excessive engine coolant, oil, and charge air (intake) temperatures, which can lead to overheating and possible engine or coolant module damage and emis- sions non-compliance.

4-12 Y53-6076-1B1 (03/17)

4

OPERATING THE ENGINE

CAUTION The winterfront is designed to min- imize the temperature differences across the radiator and reduce the possibility of cooling module dam- age. Aftermarket winterfronts may not provide the proper airflow dis- tribution and could cause cooling module damage.

Engine Control Display

Your vehicle may come with an optional Engine and Driver Information Display. This instrument records information on engine diagnostics, scheduled maintenance, driving conditions, and general trip information. The specific features of your display may vary depending on engine make. For complete information on the display see the engine manufacturer's manual.

OPERATING THE TRANSMISSION

OPERATING THE TRANSMISSION

Operating Clutch (Manual Transmission)

Manual transmissions will also have a clutch pedal situated to the left of the brake pedal. Pressing down on the clutch pedal will disengage the clutch and will allow the transmission gears to be shifted.

At the beginning of the pedal stroke, there will be about 1 3/4 in. to 2 in. (34 to 51 mm) of movement before any resistance is felt. As the pedal is pressed further, the operator will feel increased resistance as the clutch is disengaged. After the clutch has been fully disengaged, there will be another 1-1 inches (25-40 mm) of pedal travel which will engage the clutch brake. At this full stroke, the pedal will feel like it cannot be pressed anymore.

If the transmission is not shifting smoothly into gear while the clutch pedal is completely pressed to the floor, then it is time to have the clutch system inspected and serviced.

CAUTION Do not push the clutch pedal com- pletely to the floor when shifting while the vehicle is in motion. us- ing the clutch brake while shifting a vehicle in motion will damage the clutch brake. A nonfunctioning clutch brake will make shifting very difficult when the vehicle is station- ary.

If the clutch pedal is pressed completely to the floor and the transmission is not shifting, then it is time to have the clutch adjusted or serviced.

Operating Manual Transmissions

The transmission shift pattern for your vehicle may be located on the shift control knob. In addition to understanding the shift pattern and its location, you should read the transmission manufacturers manual provided with your vehicle before operating the vehicle.

OPERATING THE TRANSMISSION

Putting the Vehicle in Motion

After making sure the vehicle's oil and air pressure are correct and all other parts and systems are in proper working condition:

1. Fully depress the clutch pedal (for manual transmission) until the clutch brake makes contact.

a. The total stroke of the clutch pedal is about 6 inches (152 mm). The first inch (13 mm) is free travel. After the free travel comes the release stroke, which is the part that fully releases the clutch. The last inch (13 mm) engages the clutch brake.

b. Always start out in a low gear. Starting in higher gears, even with a light load, will cause a very jumpy start and excessive wear.

CAUTION Always use first gear or a low speed range to start the vehicle in motion. The use of a higher gear or speed range forces undue strain on the en- gine, clutch, other transmission com- ponents, and may cause damage.

2. Evaluate the road surface conditions and terrain your vehicle is on. Select a gear low enough to let your vehicle start forward with the throttle at idle.

3. Push the parking brake valve handle (Yellow) against the dash panel to release the brakes.

4. Release the clutch pedal (manual only), then gradually accelerate to permit smooth starting,

5. Do not allow your vehicle to roll (even a little) in the opposite direction during clutch engagement. If you need to

start up on an incline, apply your service brakes before you release the parking brake. Then release your service brakes as you engage the clutch and apply throttle.

For further instructions on operating your transmission, see the transmission manufacturer's Driver/Operator's Instruction Manual.

If you have a misaligned gear condition in your vehicle's transmission and cannot start, gradually release the clutch, allowing the drive gear teeth to line up properly. Then the drive gear can roll enough to allow the teeth to line up properly and complete the shift.

The best engine performance and maximum economy is obtained if gears are properly selected. This efficiency is achieved by always selecting gears within optimum engine RPM, which is where maximum torque and power are obtained. For further information, see

OPERATING THE TRANSMISSION

Driving Tips and Techniques on page 4-44.

Shifting Gears in a New Vehicle

Shift carefully in a new vehicle. The transmission may be a little stiff at first. Avoid gear clashing, by closely following these procedures.

When you are operating a new vehicle or one that has been exposed to cold weather, you want the transmission lubricant (fluid) to circulate and coat the contacting surfaces of the gears. Metal contacting metal in moving parts may seriously damage your transmission, do not drive in one gear for long periods of time until the transmission lubricant has a chance to coat all contacting surfaces.

Clutch Brake and Travel

The clutch brake is used for stopping transmission gears, allowing you to easily shift into first gear or reverse without grinding gears. Approximately the last inch (13 mm) of clutch pedal travel activates the clutch brake.

CAUTION Do not push the clutch pedal com- pletely to the floor when shifting while the vehicle is in motion. us- ing the clutch brake while shifting a vehicle in motion will damage the clutch brake. A nonfunctioning clutch brake will make shifting very difficult when the vehicle is station- ary.

To apply the clutch brake (while the vehicle is stopped) fully depress the clutch pedal to stop the gears. With the throttle at idle, select first gear then release the clutch pedal to let the

OPERATING THE TRANSMISSION

vehicle start forward, until the clutch is fully engaged. See the manufacturer's Driver/Operator's Instruction Manual for further details.

If the transmission has a butt-tooth condition and you cannot engage a gear, gradually release the clutch. Then the drive gear can roll enough to allow the teeth to line up properly and complete the shift.

During Normal Driving

If you want to shift directly into any gear other than first or reverse, depress the clutch pedal only far enough to release the clutch. Fully pressing the pedal applies the clutch brake and could cause gear hang-up.

CAUTION Be careful not to apply the clutch brake while the vehicle is moving. The purpose of the clutch brake is to stop the transmission so that you can shift into a starting gear without grinding gears. Applying the clutch brake when the vehicle is moving will render the clutch inoperative.

Double Clutching

Whether you are upshifting or down shifting, it is best to double clutch. Double clutching is easier on the transmission and on the engine, helping your vehicle match engine speed with driveline speed and achieving clash-free shifts.

To double clutch:

1. Push the clutch pedal down to disengage the clutch.

2. Move the gear shift lever to neutral.

3. Release the pedal to engage the clutch. This lets you control the RPM of the mainshaft gears, allowing you to match the RPM of the mainshaft gears to those of the output shaft.

a. Upshifts: let the engine and gears slow down to the RPM required for the next gear.

OPERATING THE TRANSMISSION

b. Downshifts: press accelerator, increase engine and gear speed to the RPM required in the lower gear.

4. Now quickly press the pedal to disengage the clutch and move the gear shift lever to the next gear speed position.

5. Release the pedal to engage the clutch.

Automatic and Automated Transmissions

An automatic or automated transmission makes shifting much easier. It remains important to completely understand how to operate the transmission to optimize its efficiency. Please read the manual for your automatic or automated transmission included with your vehicle.

For automated transmissions, there is no park position. So, you will need to apply the parking brake before leaving the cab.

Hill Hold

The hill hold feature is available as an option with certain automated transmissions. This feature holds the vehicle while on a hill to allow the operator to release the service brakes and press the accelerator. This feature will hold the vehicle if the vehicle is attempting to go up a hill from a stop in either drive or reverse.

WARNING! Do not leave the cab of your vehicle without applying the parking brake. The truck could roll and cause an accident resulting in death or per- sonal injury. Always apply the park- ing brake before you leave the cab.

OPERATING THE TRANSMISSION

WARNING! If your vehicle has an automated transmission, be aware that it can roll backwards when stopped on a hill or grade, or when starting from a stop on a hill or grade. Failure to complymay result in death, personal injury, equipment or property dam- age. Observe the following guide- lines:

When stopped on a hill or grade, press the brake pedal.

When starting from a stop on a hill or grade, quickly remove your foot from the brake pedal and firmly press on the accelerator pedal.

Auxiliary Transmission

If you have an auxiliary transmission, see your transmission manufacturers manual for its proper operation.

More Transmission Tips Riding the Clutch

The clutch is not a footrest. Do not drive with your foot resting on the clutch pedal. It will allow your clutch to slip, causing excessive heat and wear, and damage could result.

Release Bearing Wear

When you must idle your engine for any period of time, shift your transmission to neutral and disengage the clutch (take your foot OFF the pedal). This helps prevent unnecessary wear to your clutch release bearing, and it is less tiring for you, too.

Tips

Always use the clutch when making upshifts or downshifts.

Always select a starting gear that will provide sufficient gear reduction for the load and terrain.

(03/17) Y53-6076-1B1 4-19

4

OPERATING THE TRANSMISSION

Never downshift when the vehicle is moving too fast.

Never slam or jerk the shift lever to complete gear engagement.

Never coast with the transmission in neutral and the clutch disengaged.

To provide smooth gear engagements while shifting, use proper coordination between shift lever and clutch.

Double clutching is a very effective means to increase the service life of your transmission. Double clutching refers to a technique where the clutch pedal is used twice per shift instead of once. It also requires that you adjust the engine rpm in the middle of the shift which ultimately synchronizes the gears during shifting. Synchronizing reduces wear on the gears.

OPERATING THE BRAKE SYSTEM

OPERATING THE BRAKE SYSTEM

Introduction

This vehicles brake system functions with the use of compressed air generated from the engines air compressor. The compressed air is stored in various air tanks to ensure that air pressure is available whenever the driver needs it.

Compressed air is delivered to the brake system through the valve at the brake pedal and is controlled with various valves and braking circuits. The brake system is designed with separate front, rear and (when applicable) trailer circuits so that if one circuit is compromised and loses air, the other circuits will not be affected. Safety valves in each circuit will protect the other circuits in the event that a circuit loses air.

The air compressor on the engine will typically provide 100-130 psi (690-896 kPa) to the air tanks. The vehicle is also designed with an air dryer, which removes moisture from the compressed air in order to protect all components in the air system.

The brake system may be further enhanced by additional devices such as brake proportioning valves, Anti-lock braking systems or sensors designed to let you know if your brake pads need to be serviced.

Certain conditions may result in the brake surfaces getting wet. Brake surfaces that are wet do not perform as well as when they are dry. There may be situations where wet brake surfaces cannot be avoided. In such situations apply the brakes while in motion, to dry the brake surfaces.

Certain conditions may result in your brake surfaces becoming overheated (above 800 F or 427 C). Overheated brakes will damage linings and drum surfaces, ultimately decreasing braking performance. Refer to Retarders on page 4-32 and Descending a Grade on page 4-45 to avoid overheating the brakes.

This vehicle may be equipped with an anti-lock braking system (ABS). This ABS reduces the possibility of wheel lock-up. If a wheel is about to lock during braking, the ABS will automatically adjust air pressure to the brake chambers on the appropriate wheel(s) to prevent wheel lock-up. The ABS is automatically turned on when the ignition switch is turned on.

OPERATING THE BRAKE SYSTEM

WARNING! The Anti-Lock Brake System is a critical vehicle safety system. For the safety of you and others around you, have the vehicle sub- mitted for periodic preventive main- tenance checks as well as having any suspected problems immedi- ately checked by an authorized dealer. Failure to properly maintain your brake system can lead to se- rious accidents. Failure to comply may result in death, personal injury, equipment or property damage.

WARNING! Do not drive through water deep enough to wet brake components, as it may cause the brakes to work less efficiently than normal. The vehicle's stopping distance may be longer than expected, and the vehi- cle may pull to the left or right when brakes are applied, which could contribute to an accident involving death or personal injury.

WARNING! Do not rely on an anti-lock brake sys- tem that is functioning improperly. You could lose control of the vehi- cle resulting in a severe accident, causing death or personal injury. If your ABS lamp goes on while you are driving or stays on after the self- check, your anti-lock system might not be working. The ABS may not function in an emergency. You will still have conventional brakes, but not anti-lock brakes. If the lamp in- dicates a problem, have the ABS checked.

Vehicles without anti-lock brake systems (ABS) are typically equipped with a bobtail brake proportioning system. When a trailer is not connected, the drive axle brake application pressure will automatically be limited by the proportioning system. When driven in a bobtail mode,

4-22 Y53-6076-1B1 (03/17)

4

OPERATING THE BRAKE SYSTEM

these tractors will require greater brake pedal application to provide the equivalent braking to a bobtail tractor not equipped with a proportioning system.

Trailer ABS Power Line Communication (PLC)

North American on-highway vehicles are equipped with a separate electrical circuit to power the anti-lock brake system (ABS) on towed vehicle(s). In most cases, the ABS power will be supplied through the Auxiliary circuit on the primary 7-way trailer light line connector. If the vehicle was manufactured with a switchable Auxiliary circuit for trailer accessories, an additional 7-way connector would have been provided for trailer ABS power. In either case, the ABS power line on the vehicle will be PLC equipped.

CAUTION Do not splice into the non-switchable auxiliary circuit on the primary 7-way trailer light line. Doing so may cause the trailer ABS to malfunction. This circuit is dedicated for trailer ABS power. To add a switchable auxiliary circuit, contact a dealership.

Vehicles and trailers built after 3/1/01 must be able to turn on an In-Cab Trailer ABS Warning Lamp (per Federal Motor Vehicle Safety Standards (FMVSS) 121). The industry chose Power Line Communication (PLC) as the standard method to turn it on.

NOTE Trailers not equipped with PLC can not turn on the In-Cab Trailer ABS Warning Lamp.

(03/17) Y53-6076-1B1 4-23

4

OPERATING THE BRAKE SYSTEM

NOTE For doubles or triples, the lamp does not distinguish between trailers. An ABS problem in any of the trailers will activate the Trailer ABSWarning Lamp.

NOTE If you change the intended service in any way (i.e. number of axles, mul- tiple trailers, add switchable trailer accessories, etc.) from the date the vehicle was manufactured, you should contact your trailer manufac- turer and/or trailer anti-lock brake manufacturer to determine if the power available at the 7-way trailer light line is adequate. Failure to do so might result in insufficient power to the trailer ABS system which may affect its operation.

CAUTION The center pin of the 7-way trailer light line may be constantly powered for ABS. Make sure it will not acci- dently turn on trailer equipment.

Special Trailer ABS (Without PLC) Option

If a trailer does not have PLC, but it does have ABS that is powered through an optional second trailer connector (ISO 3731) and that trailer ABS is designed to control the Trailer ABS Warning Lamp in the cab and the vehicle has been ordered with the option to turn on this lamp for these types of trailers, then this lamp will turn on when that trailer ABS has a system problem. This should be checked by a dealer as soon as possible. The Trailer ABS Warning Lamp will not turn on for the power-on test when connected to these types of trailers.

NOTE Very few trailers built before 3/1/01 have this option. Trailers built after 3/1/01 are built with PLC technology.

OPERATING THE BRAKE SYSTEM

Advanced ABS with Stability Control

This vehicle may be equipped with an optional Electronic Stability Control (ESC). ESC is a feature for ABS-equipped vehicles that reduces the risk of rollovers, jackknifing and other loss of control situations. ESC features include Roll Stability Program (RSP) and Yaw Control.

During operation, the ECU of the Bendix Advanced ABS system constantly compares performance models to the vehicles actual movement, using the wheel speed sensors of the ABS system, as well as lateral, yaw, and steering angle sensors. If the vehicle shows a tendency to leave an appropriate travel path, or if critical threshold values are approached, the system will intervene to assist the driver.

Roll Stability Program

Bendix RSP, an element of the overall ESC system, addresses rollover conditions. In the case of a potential roll event, the ECU will override the throttle and quickly apply brake pressure at all wheel ends to slow the vehicle combination. The level of braking application during an RSP event will be proportional to roll risk.

A Real World Example of How the RSP System Operates

Excessive speed for road conditions creates forces that exceed the threshold at which a vehicle is likely to rollover on a higher-friction surface.

The system automatically reduces engine torque and applies the service brakes (based on the projected rollover risk) to reduce the vehicle speed,

thereby reducing the tendency to roll over.

RSP Example

OPERATING THE BRAKE SYSTEM

Yaw Stability

Yaw stability counteracts the tendency of a vehicle to spin about its vertical axis. During operation, if the friction between the road surface and the tires is not sufficient to oppose lateral (side) forces, one or more of the tires can slide, causing the truck/tractor to spin.

These yaw events are referred to as either under-steer (where there is a lack of vehicle response to steering input due to tire slide on the steer axle) or over-steer (where the tractor's rear end slides out due to tire slide on the rear axle) situation. Generally, shorter wheelbase vehicles (tractors, for instance) have less natural yaw stability, while longer wheelbase vehicles (straight trucks, for instance) have greater natural yaw stability. Factors that influence yaw stability are: wheelbase, suspension, steering geometry, weight distribution front to rear, and vehicle track width.

Yaw Control

Yaw Control responds to a wide range of low- to high-friction surface scenarios including rollover, jackknife and loss of control. In the case of vehicle slide (over-steer or understeer situations), the system will reduce the throttle and then brake one or more of the four corners of the vehicle (in addition to potentially applying the trailer brakes), thus applying a counter-force to better align the vehicle with an appropriate path of travel. For example, in an over-steer situation, the system applies the outside front brake; while in an under-steer condition, the inside rear brake is applied.

A Real World Example of How Yaw Control Operates

Excessive speed exceeds the threshold, creating a situation where a vehicle is likely to spin and jackknife.

The Bendix Yaw Control system reduces engine throttle and selectively applies brakes to reduce the vehicle speed, thereby reducing the tendency to jackknife.

Yaw Control Example

OPERATING THE BRAKE SYSTEM

ESC May Reduce The Vehicle Speed Automatically

To minimize unexpected deceleration and reduce the risk of a collision the operator must:

Avoid aggressive driving maneuvers, such as sharp turns or abrupt lane changes at high speeds, which might trigger the stability system.

Always operate the vehicle safely, drive defensively, anticipate obstacles and pay attention to road, weather and traffic conditions. ABS, ATC and ESC stability systems are no substitute for prudent, careful driving.

Towing Doubles Or Triples May Reduce The Effectiveness Of Stability Systems

ESC is designed and optimized for trucks and for tractors that tow single trailers. If a tractor equipped with ESC is used to power multiple trailer combinations (known as doubles or triples) the effectiveness of the ESC system may be greatly reduced.

WARNING! Exercise extreme care when tow- ing doubles or triples with a vehicle equipped with Electronic Stabil- ity Control. Excessive speed and aggressive maneuvers, such as sharp turns, sudden steering inputs or abrupt lane changes should be avoided because these maneuvers could cause loss of vehicle control possibly resulting in an accident in- volving death or personal injury.

Limitations Of Stability Systems

The ESC stability systems effectiveness may be greatly reduced if:

The load shifts due to improper retention, accident damage or the inherently mobile nature of some loads (for example, hanging meat, live animals or partially laden tankers),

The vehicle has an unusually high or off-set center of gravity (CG),

One side of the vehicle drops off the pavement at an angle that is too large to be counteracted by a reduction in speed,

The vehicle is used to haul double or triple trailer combinations,

If very rapidly winding steering inputs are inputted at high speeds,

(03/17) Y53-6076-1B1 4-27

4

OPERATING THE BRAKE SYSTEM

There are mechanical problems with suspension leveling of the tractor or trailer resulting in uneven loads,

The vehicle is maneuvering on a high banked road creating either additional side forces due to the weight (mass) of the vehicle or a deviation between expected and actual yaw rates,

Gusty winds are strong enough to cause significant side forces on the vehicle and any towed vehicles.

To Maximize The Effectiveness Of ESC

Loads must be properly secured and evenly distributed at all times.

Drivers need to exercise extreme caution at all times, and avoid sharp turns, sudden steering inputs or abrupt lane changes at high speeds, particularly if:

a. the vehicle hauls loads that could shift,

b. the vehicle or load has a high or off-set center of gravity (CG) when loaded, or

c. the vehicle tows doubles or triples.

Truck Chassis Modifications

The ESC system was specifically calibrated and validated only for your vehicles original factory-built configuration. If your vehicles chassis components are altered (for example, a wheelbase extension or reduction, tag axle addition or removal, tractor to truck conversion or steering system component change) the ESC system must be disabled immediately by a qualified mechanic.

WARNING! Failure to disable ESC Electronic Stability Control when modifying a vehicle could result in a loss of ve- hicle control possibly resulting in an accident involving death or personal injury.

OPERATING THE BRAKE SYSTEM

WARNING! For vehicles equipped with ESC Electronic Stability Control do not replace the vehicles steering wheel with an aftermarket or different part number than originally supplied. Us- ing a different steering wheel could cause ESC to malfunction causing a loss of vehicle control possibly resulting in an accident involving death or personal injury.

Steering Angle Sensor Re-Calibration

Whenever maintenance or repair work is performed to the steering mechanism, linkage, gear, adjustment of the wheel track, or if the steering angle sensor is replaced or the steering wheel is changed or re-centered, the Steering Angle Sensor must be re-calibrated.

WARNING! If the Steering Angle Sensor is not re-calibrated, the Yaw Control sys- tem will not function properly. A un- calibrated sensor could result in a loss of control of your vehicle which can lead to an accident involving death or personal injury.

ATC Functions (standard)

Your truck/tractor ABS is equipped with an automatic traction control (ATC) feature. This feature is controlled by a switch as shown in the next illustration. This feature is monitored by a warning lamp located on the switch.

Automatic Traction Control Warning Lamp

The Traction Control warning lamp on page 3-23 will briefly illuminate and then go out when the ignition switch is first turned on. The traction control warning lamp will illuminate whenever the ATC system detects drive wheel spin. The lamp will remain illuminated as long as wheel spin is detected and the ATC system is applying the

(03/17) Y53-6076-1B1 4-29

OPERATING THE BRAKE SYSTEM

drive wheel brakes or reducing engine torque. Engine torque or vehicle speed should be reduced to eliminate wheel spin and prevent excessive application of the ATC system. Except for checking for proper illumination of the ABS and traction control warning lamps when first starting the vehicle, and for monitoring these lamps while driving, no special operating procedures are required. For detailed system description, see literature for your specific ABS that was provided with your vehicle.

This feature helps improve traction when vehicles are on slippery surfaces or surfaces with poor traction (i.e. mud or snow) by reducing drive wheel overspin. Automatic traction control works in two different ways:

If a drive wheel starts to spin, ATC applies air pressure to brake the wheel. This transfers engine

torque to the wheels with better traction.

If all drive wheels spin, ATC reduces engine torque to provide improved traction.

ATC turns itself on and off, you do not have to select this feature. If drive wheels spin during acceleration, the ATC Warning Lamp comes on, indicating wheel spin control is active.

Do not allow the ATC Warning Lamp to remain on continuously for an extended length of time. Extended, continuous use of the ATC can cause overheating of the drive wheel brakes.

Deep Snow and Mud Switch (option)

A deep snow and mud switch is included with Wheel Spin Control. The Deep Snow and Mud feature is helpful during acceleration. This function increases available traction on extra soft surfaces like snow, mud or gravel,

by slightly increasing the permissible wheel spin. When this function is in use, the ATC Warning Lamp blinks continuously.

Off-Road ABS Function Switch (option)

Your vehicle may be equipped with a separate switch to activate an Off-Road ABS function. This function is NOT to be used for On-Highway driving but is intended to be used to improve stopping performance in Off-Highway conditions (e.g. loose gravel and mud). The Off-Road ABS function is accomplished by allowing a wedge of material to build-up in front of momentarily locked wheels.

Features and Benefits

Changes the ABS control limits to allow for a more aggressive ABS function while off-road.

4-30 Y53-6076-1B1 (03/17)

4

OPERATING THE BRAKE SYSTEM

Improves vehicle control and helps reduce stopping distances in off-road conditions or on poor traction surfaces such as loose gravel, sand and dirt.

Allows retarders to function independently of the ABS function.

If your vehicle does not have an engine retarder, the Off-Road ABS switch will function the same.

CAUTION Never drive your vehicle on im- proved roads/highways with the Off-Road ABS function turned on. When you drive your vehicle onto an improved road surface or highway, immediately turn off the Off-Road ABS switch. Failure to do so will cause the ABS system to not func- tion properly in an ABS event under 25 mph and could result in an acci- dent or personal injury.

WARNING! While the off-road mode can im- prove vehicle control and shorten stopping distances, some steering ability may be reduced on certain surfaces resulting from the momen- tarily sliding tires. Always oper- ate your vehicle at safe operating speeds. Failure to do so may cause you to lose control of the vehicle and could result in an accident or personal injury.

How The Off-Road ABS Function Works

The ABS lamp flashes slowly during off-road mode engagement. This is done to alert you of a modification to the ABS control software.

At speeds above 25 mph, the ABS controller operates in the normal on-highway mode.

At speeds between 10 and 25 mph, the ABS control software is modified to allow short periods (0.25 seconds) of locked-wheel cycles.

At speeds below 10 mph, the ABS control software is turned off to allow locked wheels.

When the Off-Road ABS function is enabled, the Retarder Disable output is turned off; that is, the engine retarders are left to function without ABS intervention. For additional information, see the Off-Road ABS pamphlet in your vehicles glove box.

OPERATING THE BRAKE SYSTEM

Retarders

Various retarders are available which function against the engine, driveline, or transmission. These are devices that use your engines power to slow down your vehicle. They save wear and tear on your service brakes and can be a safety feature, too, because they can keep your brakes from overheating.

Ideally, you should always slow your vehicle with your retarder (where permitted by law) and use your service brakes only for stopping completely. Operating this way will greatly prolong the life of your brakes.

WARNING! Do not use any of the vehicles re- tarders in any situation that requires an immediate stop and/or in situa- tions of poor traction (such as wet, icy or snow covered roads). Trying to use the retarder instead of the ser- vice brakes may cause a loss of ve- hicle control which may result in an accident involving death or personal injury.

WARNING! The service brakes must be used in an emergency. The retarder alone might not stop you fast enough to prevent an accident. Failure to com- ply may result in death, personal in- jury, equipment or property damage.

The retarder is NOT intended as the primary brake for the vehicle, nor is it an emergency brake. The retarder only helps the service brakes by using

pressure to slow the drivetrain. Use the service brakes for quick stops.

Do not use the retarder when operating on road surfaces with poor traction (such as wet, icy, or snow covered roads or gravel). Retarders can cause the wheels to skid on a slippery surface.

OPERATING THE BRAKE SYSTEM

Driving Bobtail or with an Unloaded Trailer

We recommend that you do not use your engine retarder to slow down when you are bobtailing or pulling an empty trailer.

WARNING! Using an engine retarder can cause a wheel lockup. The trailer is not loading the tires enough to give the traction you may need. When you are bobtail or unloaded, you can have a serious accident if your wheels lock suddenly during brak- ing. You could be killed or injured. Dont use your retarder when you are driving bobtail or with an un- loaded trailer.

Transmission Retarder

If you have this option, it will act like a brake to slow your vehicle without using the brakes. Take your foot off the throttle and operate the retarder switch. When you do not need full retarder effect, you can apply it intermittently (off and on) to cause gradual or partial slowing. Continuous application of your retarder will cause your hydraulic fluid to get hotter. Intermittent application will help prevent overheating.

WARNING! Do not rely on your automatic trans- mission hydraulic retarder to stop your vehicle. If your engine shuts down, the vehicles retarder will cease to operate which may lead to an accident involving death or personal injury. Always be ready to suddenly apply the service brakes.

OPERATING THE BRAKE SYSTEM

Parking Brake

1. Normal Run Position 2. Trailer Park With Vehicle

Released 3. System Park or Trailer

Charge With Vehicle Parked

Parking brakes work in reverse action of the regular brakes. When the parking brakes are engaged, air is exhausted from the spring chambers which allow the spring to engage the brakes. This design also provides for the safety function if a brake circuit has a leak and loses air. In such a scenario, the parking brakes will apply.

The vehicles parking brake controls are the yellow diamond shaped knob on your dashboard. If the vehicle is equipped to tow a trailer, then there will be an additional red octagon shaped knob for the trailer parking brakes. Parking brakes will be engaged when either of these knobs are pulled OUT. (If one knob is pulled out, the other knob will automatically pop out.)

Pushing IN a knob will disengage the respective parking brakes. If you push in the yellow knob only, you will disengage the vehicles parking

brakes but will not disengage the trailer parking brakes (if applicable). Either knob will pop back out if the system pressure is not above 60 psi (414 kPa).

The instrument panel display will provide a message any time the parking brakes (vehicle or the trailer) are set and the vehicle is put into motion.

To Turn On:

Press the ON/OFF button.

To Turn Off:

Press the ON/OFF button. Any previous speed settings are cleared.

Using Cruise Control While Driving

Setting Cruise Speed

1. Ensure that the vehicle speed is above the minimum cruise control speed (19 mph (30 km/h) for PACCAR MX engine and 30

mph (48 km/h) for the Cummins engines) and the engine speed is above 1100 rpm.

2. Press the "ON/OFF" button.

3. Accelerate the vehicle to the desired cruise speed.

4. Press the "SET" button to set the cruise speed.

NOTE Cruise Control may not hold the set speed going down hills. If the speed increases going down a hill, use the brakes to slow down. This will can- cel Cruise Control.

Changing the Cruise Set Speed

For vehicles with cruise control buttons on the steering wheel, the cruise speed may be changed by using the +/- button. The pressing and holding the + button will increase speed while pressing and holding the - button will decrease speed. For vehicles with dash mounted cruise control switches, changing the speed is done through the "Set/Resume" button. To increase the speed, press and hold the Set button. To decrease the speed, press and hold the "Resume" button.

Cancelling Cruise Control

You can cancel cruise control in any of these ways:

Tap the brake pedal.

Tap the clutch pedal.

CRUISE CONTROL

Press the ON/OFF button if the vehicle has dashboard-mounted cruise control switches or the CANCEL button if the vehicle has cruise control switches on the steering wheel.

Resuming Cruise Control

1. If you tapped the brake or clutch pedal, the cruise control remembered the previously set cruise speed. To resume that set speed, accelerate above the minimum cruise control speed and press the "RESUME" button.

2. If you pressed the "OFF" button (or the steering wheel mounted "CANCEL" button) or turned the ignition key OFF, this cleared the system memory and you will need to set a new cruise speed.

Using Cruise Control for Stationary PTO Operation

Setting Idle Speed

1. Ensure parking brakes are applied.

2. Ensure transmission is in Neutral.

3. Engage PTO per the manufacturer's operating instructions.

4. Press the "ON" button.

5. Press the "SET" button to obtain the desired engine rpm.

Cancelling Cruise Control

You can cancel cruise control in any of these ways:

Tap the brake pedal.

Tap the clutch pedal.

Press the "OFF" button (or the steering wheel mounted "CANCEL" button).

NOTE Cruise control functions and fea- tures may vary depending upon which engine you have. For specific explanation of your cruise control, see the cruise control or engine manual included with your vehicle.

This vehicles electronic system will perform a rationality check every time the vehicle is started. This check is to ensure that the service brakes are working before allowing cruise control to function. This safety feature is designed to ensure that a driver is able to cancel the cruise set speed by using the service brake pedal. The system will not allow cruise control operation if it does not pass the rationality check. The instrument cluster will prompt you to press the service brake pedal if it has not been pressed since the vehicle has been started.

AXLE

AXLE

Differential Lock

The vehicle may be equipped with switches to lock the either of the rear axle differentials. Depending on how the vehicle is specified, a combination individual switches may be available that can lock the interaxle driveline and/or any combination of the forward rear or rear-rear driving axles.

The interaxle differential switch allows each axle to turn independently. In certain situations, engaging the interaxle differential lock relieves stress on the rear axles and reduces tire wear. Engaging this switch will also provide better traction in slippery or loose gravel conditions.

In the LOCK position, continuous operation on paved, dry surfaces, put stress on the axles, and can possibly damage the internal gears. The switch has a guard to prevent accidental operation of the switch.

Locking the differentials is typically used during ice or snow conditions and without tire chains, unpaved roads that have loose sand, mud or uneven surfaces. Look ahead and predict when the differential needs to be locked. Stop the vehicle and lock the differentials before approaching.

While using the differential in the locked position, do not exceed 25 mph (40 km/h). When disengaging the differential lock, reduce the throttle to prevent drivetrain damage.

WARNING! Do not put the differential lock in the LOCK position while the wheels are spinning freely (slipping), you could lose control of the vehicle or cause axle damage. Switch to LOCK only when the wheels are not spinning. Failure to comply may result in death, personal injury, equipment or property damage.

Setting Ride Height

Vehicles equipped with rear air suspensions have their ride height and axle (pinion) angle(s) preset at the factory. These are precision settings and should not be altered. Incorrectly adjusted ride height may result in improper interaxle U-joint working angles. This can result in pre-mature driveline wear and driveline vibration. If your vehicle is equipped with a Peterbilt rear air suspension, and if it becomes necessary to reset the ride height, you may temporarily set it by following the next procedure.

Follow this procedure to temporarily set ride height.

WARNING! Ensure that a vehicle is parked and the wheels chocked before begin- ning this procedure.

CAUTION Completing this procedure will en- able you to safely reach the nearest authorized Peterbilt repair facility to have ride height and pinion angle re- set using the proper equipment and technique. Do this as soon as possi- ble to avoid potential driveline dam- age.

NOTE Suitable wheel chocks are at a min- imum an 18-inch (46 cm) long 4x4.

1. Ensure that the tractor is fully laden during this procedure. Do not use these procedures on a vehicle that is not laden (bobtail).

2. Ensure the air supply and delivery plumbing of the height control valve is consistent with the following illustrations.

NOTE At least one of the mounting

holes in the height control valve bracket will be slotted to permit rotating the valve.

On dual-valve systems, begin with the LH valve on the next step.

3. Loosen the fasteners mounting a height control valve to its bracket.

WARNING! The rear of a vehicle will

drop about 3 1/2 inches (88 mm) when the air springs are deflated. Ensure that no persons or objects that could be killed, injured or damaged are under the vehicle before deflating the air springs.

To minimize risk of death, personal injury or property damage, do not use a dump valve to deflate the air springs. Rotate the height control valve(s) manually to ensure positive control of air spring deflation.

To minimize risk of death or personal injury, keep away from air springs as they are being inflated.

4. Rotate the valve either clockwise or counterclockwise until air pressure in the air springs provides the ride height specified for that suspension. Measure the ride height from the bottom of the frame rail to the approximate centerline of the rearmost drive axle hub:

For tandem axles, make the vertical measurement at the centerline of the suspension (see illustration on page 4-40).

For a single axle, make the measurement in front of the axle, in the area forward of the tires but not past the suspension bracket.

5. When at the correct ride height, ensure that the height control valve lever is in the neutral position, then install either the built-in alignment pin or a 1/8-inch (3-mm) dowel (see illustration on page 4-40).

6. Torque the mounting fasteners to 55-75 Lb. in. (6.2-8.5 Nm.).

7. Remove the alignment pin or dowel.

8. Repeat Steps 2 through 6 above for the RH valve on vehicles with a dual-valve system.

Driving with Deflated Air Springs

If an air spring is ruptured, there will be enough air pressure to drive the vehicle to a safe stop off the highway to investigate the problem.

WARNING! Do not continue to drive with rup- tured air springs. The air loss can cause the spring brakes to apply al- lowing your brakes to drag and burn up the linings, which could lead to an accident causing death or personal injury. Do not continue to operate the vehicle in this condition.

You can get to a repair facility if you do the following:

1. Remove the height control link connected to the axle and to the suspension air valve control arm. This will cause the air valve

control arm to center in the closed position.

2. The air system can then be pumped up to normal pressure for continued operation.

WARNING! Do not drive the vehicle if the air pressure is less than 100 psi (690 kPa). Driving the vehicle with less than 100 psi (690 kPa) could make the brakes unsafe to use which could cause an accident involving death or personal injury.

CAUTION Operating a vehicle with air suspen- sion bags either overinflated or un- derinflated may cause damage to driveline components. If a vehicle must be operated under such condi- tions, do not exceed 5 mph (8 km/h).

AFTER-TREATMENT SYSTEM

AFTER-TREATMENT SYSTEM

Introduction

This vehicle will has an exhaust After-Treatment System (ATS), to control vehicle exhaust emissions, which consist of a Diesel Particulate Filter (DPF), Selective Catalyst Reduction (SCR), Regeneration Switch and warning lights. The DPF will trap soot from the engine exhaust gases. The SCR uses Diesel Exhaust Fluid to reduce the levels of NOx in the engine exhaust. The ATS will periodically clean (regenerate) the DPF. Please refer to the Exhaust Aftertreatment System Supplement provided with the vehicle for more detailed description of functionality and warnings.

DRIVING TIPS AND TECHNIQUES

DRIVING TIPS AND TECHNIQUES

Introduction

This section covers additional driving tips and techniques on how to drive your vehicle more efficiently.

Coasting

WARNING! Do not coast with the transmission in neutral or with the clutch pedal depressedit is a dangerous prac- tice. Coasting in neutral may result in damage to your drivetrain when you try to re-engage the transmis- sion. You could lose control of the vehicle which can lead to an acci- dent involving death or personal in- jury.

Do not coast with the transmission in neutral or with the clutch pedal depressed. Besides being illegal and dangerous, coasting is also expensive. It causes premature failure or damage to the clutch and transmission and overloads the brake system.

Coasting with the transmission in neutral also prevents proper transmission component lubrication. During coasting the transmission is driven by the rear wheels, and the countershaft gear (which lubricates the transmission components by oil splash) will only be turning at idle speed.

DRIVING TIPS AND TECHNIQUES

Descending a Grade

WARNING! Do not hold the brake pedal down too long or too often while going down a steep or long grade. This could cause the brakes to overheat and reduce their effectiveness. As a result, the vehicle will not slow down at the usual rate. To reduce the risk of an accident which could cause death or personal injury, before go- ing down a steep or long grade, re- duce speed and shift the transmis- sion into a lower gear to help control your vehicle speed. Failure to follow procedures for proper downhill oper- ation could result in loss of vehicle control.

Engine Overspeed

CAUTION To avoid engine damage, do not let the engine rpm go beyond the maxi- mum governed rpmvalve damage could result if overspeed conditions occur.

NOTE Often these recommendations are secondary to maintaining an ade- quate and safe speed relative to the surrounding traffic and road condi- tions.

Operate the engine within the optimum engine rpm range and do not allow the rpm's to exceed the maximum governed speed. See your Engine Operation and Maintenance Manual for information regarding engine rpm. When the engine is used as a brake to control vehicle speed (e.g., while driving down a grade), do not allow

the engine rpm to exceed maximum governed speed.

Under normal load and road conditions operate the engine in the lower end of the range.

DRIVING TIPS AND TECHNIQUES

Use of Tachometer

The tachometer is an instrument that aids in obtaining the best performance of the engine and manual transmission, serving as a guide for shifting gears.

Refer to the Engine Operation and Maintenance Manual for optimum engine rpm.

If the engine rpm moves beyond the maximum governed speed, indicating an overspeed condition, apply the service brake or shift to a higher gear to bring engine rpm within the optimum speed range.

When driving downhill: shift to a lower gear, use the engine brake (if so equipped), and use the service brake, keeping the engine speed below 2,100 rpm.

When the engine speed reaches its maximum governed speed, the injection pump governor cuts off fuel

to the engine. However, the governor has no control over the engine rpm when it is being driven by the vehicle's transmission, for example, on steep downgrades. Apply service brakes or shift to a higher gear.

Fuel economy and engine performance are also directly related to driving habits:

The best results in trip time and fuel economy are obtained while driving the vehicle at a steady speed.

Shift into higher or lower gears (or apply the service brake) to keep engine rpm near the lower end of the optimum operating range.

Avoid rapid acceleration and braking.

WARNING! Do not look at the Instrument Clus- ter Display for prolonged periods or repeatedly in a short period of time while the vehicle is moving. Ex- tended glance durations to instru- ment cluster and/or overly frequent glances inside the vehicle can cause a loss of attention to the situations on the roadway and vehicles road po- sition, which could lead to an acci- dent and possible death or personal injury or equipment damage.

DRIVING TIPS AND TECHNIQUES

Use of Instrument Cluster Display

The Instrument cluster display provides information to help the driver optimize vehicle efficiency. Refer to Instrumentation Cluster Information on page 3-35 for details. A driver will find the section describing Trip Information and the RPM Detail useful.

Fuel - Excess Consumption

The vehicle's fuel consumption is connected to five important factors: maintenance, driving habits, general condition of the road, traffic conditions, and vehicle load.

Maintenance

Proper maintenance will keep the vehicle running like new even after long periods of use. The driver must perform the daily and weekly checks of the vehicle.

(03/17) Y53-6076-1B1 4-47

DRIVING TIPS AND TECHNIQUES

Maintenance factors affecting fuel consumption:

air and/or fuel filters partially clogged

engine valves out of adjustment

injection pump improperly synchronized

injection nozzles defective or uncalibrated

improperly inflated tires

wheel bearings improperly adjusted

clutch improperly adjusted or worn (slipping)

fuel leaks

Driving Habits

Wrong driving habits must be corrected and the recommendations on economic driving should be followed.

Driving factors affecting fuel consumption:

excessive speed and unnecessary fast acceleration

long periods of idling

driving with foot resting on the (manual transmission) clutch pedal

General Condition

Other factors affecting fuel consumption are related to loads and type of roads on which the vehicle operates. It is not always possible to choose the most adequate road, but it must be kept in mind that the ideal road is the one that allows a steady speed in high gear, without requiring frequent braking and acceleration.

The following general conditions can affect fuel consumption:

overload

unbalanced load

very high load

inadequate roads

traffic conditions

SLEEPER BUNKS

SLEEPER BUNKS

Sleeper Bunk

If your vehicle has an upper and lower bunk, the upper bunk can be folded up out of the way to provide you with more dressing area in the sleeper cab. The lower bunk has storage underneath it to stow your luggage and other belongings. The upper bunk weight limit is 320 lb (145 kg).

WARNING! Be sure the restraint system is used when anyone is occupying the sleeper while the vehicle is moving. In an accident, an unrestrained per- son lying in a sleeper bunk could be injured. He or she could be thrown from the bunk.

WARNING! Always keep the lower bunk in its down (latched) position while the ve- hicle is moving. If left open, stored items could become loose during an accident and strike you. Before you move the vehicle, check to be sure the lower bunk is latched securely. Failure to comply may result in death or personal injury.

Before you move the vehicle, check to be sure the lower bunk is latched securely.

To Lower Upper Bunk: pull on the lanyard in the upper left corner of the bunk to release the bunk. This will free it from the anchored position and allow you to lower the bunk.

To Raise Upper Bunk: fold the upper bunk up and push it against the retaining latch until you hear a click.

Pull on the bunk to be sure it is latched securely.

WARNING! Be sure the latch that holds the up- per bunk in the folded position is working properly so the bunk will not fall down. If the bunk falls, you could be injured.

WARNING! Be sure to stow away all loose be- longings before you move your ve- hicle. Do not store objects on the bunks, they could cause damage or injury in an accident. Failure to com- ply may result in death, personal in- jury, equipment or property damage.

SLEEPER BUNKS

WARNING! Be sure the restraint system is used when anyone is occupying the sleeper while the vehicle is moving. In an accident, an unrestrained per- son lying in a sleeper bunk could be injured. He or she could be thrown from the bunk. Failure to comply may result in death or personal in- jury.

WARNING! Be sure no one ever rides unse- cured in the upper bunk. That per- son could be thrown out in an acci- dent and could be injured. Do not use the upper bunk while you are moving. Failure to comply may re- sult in death or personal injury.

Sleeper Occupant Restraint

The sleeper restraint is stored in a compartment on the rear sleeper cab wall.

WARNING! Failure to properly use the sleeper restraint when an individual is lo- cated in the sleeper bunk and the ve- hicle is moving can result in death or personal injury.

See Sleeper Bunks and Restraints on page 1-27, for more information on cab/seat restraint systems.

STOPPING THE ENGINE

STOPPING THE ENGINE

Before Stopping the Engine

A hot engine stores a great amount of heat. It doesnt cool down immediately after you shut it off. Always cool your engine down before shutting it off. You will greatly increase its service life.

Idle the engine at 1000 RPM for five minutes. Then low idle for thirty seconds before shutdown. This will allow circulating coolant and lubricating oil to carry away heat from the cylinder head, valves, pistons, cylinder liners, turbocharger, and bearings. This way you can prevent serious engine damage that may result from uneven cooling.

Turbochargers

This cooling-down practice is especially important on a turbocharged engine. The turbocharger contains bearings and seals that are subjected to hot exhaust gases. While the engine is operating, heat is carried away by circulating oil. If you stop the engine suddenly, the temperature of the turbocharger could rise as much as 100F (55C) above the temperature reached during operation. A sudden rise in temperature like this could cause the bearings to seize or the oil seals to loosen.

Refueling

Air inside the fuel tanks allows water to condense in the tank. To prevent this condensation while the vehicle is parked for extended periods of time, fill the tanks to 95 percent of capacity. Never fill to more than 95 percent capacity as this provides room for expansion resulting from temperature extremes. When refueling, add approximately the same amount to each fuel tank on vehicles with more than one tank.

WARNING! Do not carry additional fuel contain- ers in your vehicle. Fuel containers, either full or empty, may leak, ex- plode, and cause or feed a fire. Do not carry extra fuel containers, even empty ones are dangerous. Failure to comply may result in death, per- sonal injury, equipment or property damage.

(03/17) Y53-6076-1B1 4-51

STOPPING THE ENGINE

WARNING! Diesel fuel in the presence of an ig- nition source (such as a cigarette) could cause an explosion. A mixture of gasoline or alcohol with diesel fuel increases this risk of explosion. Do not remove a fuel tank cap near an open flame. Use only the fuel and/or additives recommended for your en- gine. Failure to comply may result in death, personal injury, equipment or property damage.

Specification: Use only Ultra Low Sulfur Diesel (ULSD) Fuel, as recommended by engine manufacturers. If you need further information on fuel specifications, consult the Engine Operation and Maintenance Manual.

Location of Fuel Shut-Off Valves

If your vehicle is equipped with shut-off valves for the take-off and return lines, they are located on the fuel lines entering the top of the fuel tank. Fuel shut-off valves for the fuel crossover line are on the bottom of the fuel tank, at the crossover line connection.

Refuel Before the Final Stop

Air space in your fuel tanks allows water to condense there. To prevent this condensation while you are stopped, fill your tanks to 95% of capacity.

STOPPING THE ENGINE

Final Stop

To make sure your vehicle is ready to go after a long stop (such as over night), please follow the suggestions below. Your vehicle will be easier to get going when you are ready, and it will be safer for anyone who might be around it. Please remember, too, that in some states it is illegal to leave the engine running and the vehicle unattended.

Final Stopping Procedures

1. Set the parking brake before leaving the drivers seat. To hold your vehicle while it is parked, dont rely on:

Air Brakes

Hand Control Valve for Trailer Brakes

Engine Compression

WARNING! Using the trailer hand brake or air brakes to hold a parked vehicle is dangerous. Because they work with air pressure, these brakes could come loose. Your vehicle could roll, causing an accident involving death or personal injury. Always set the parking brakes. Never rely on the trailer hand brake or truck air brakes to hold a parked vehicle.

2. If you are parked on a steep grade, block the wheels.

Suitable wheel chocks are at a minimum an 18-inch (46-cm) long 4x4.

Blocked Wheels

3. Drain water from the air reservoirs. While the engine and air supply system are still warm, drain moisture from the air reservoirs. Open the reservoir drains just enough to drain the moisture. Dont deplete the entire

STOPPING THE ENGINE

air supply. Be sure to close the drains before leaving the vehicle.

Opening Drains

4. Secure the vehicle. Close all the windows and lock all the doors.

Common Maintenance Items Accessory Drive Belts

You can extend the reliability and service life of your vehicle's drive belts with proper attention to installation, and maintenance. Neglect could cause belt failure. The result could be the loss of the electrical or air system as well as possible engine damage from overheating. So it's a very good idea to check your belts frequently and replace them as soon as you detect trouble.

Inspection of the Engine Oil Level

NOTE It takes approximately 15 minutes for all the oil to run into the sump when the engine is warm. If the level is checked immediately after switching off the engine, the dipstick will show a low oil level.

4-54 Y53-6076-1B1 (03/17)

STOPPING THE ENGINE

1. Make sure that the vehicle frame rail is standing on a flat and level surface.

2. Make sure that the vehicle is horizontal, both lengthwise and crosswise. Check this carefully on a vehicle with air suspension. Note that the engine may be inclined up to 4 depending on the vehicle model and wheelbase.

3. Twist the dipstick handle to unlock it, then pull the dipstick out of the holder.

4. Wipe the dipstick clean with a lint-free cloth.

5. Place the dipstick back into the holder.

6. Pull the dipstick out again and check the oil level. The oil level should always be between the 2 marks on the dipstick.

7. Reinstall the dipstick and twist to lock it in place.

1. Engine Oil High Level 2. Engine Oil Low Level

Topping Up the Engine Oil

1. Top up with oil, if necessary, via the filler opening. Use the correct grade in the correct quantity. For oil replacement, please see engine Operators Manual included with this chassis.

2. After topping up, wait 1 minute and check the oil level again.

3. Reinstall the oil fill cap and twist to lock it in place.

STOPPING THE ENGINE

Engine Air Intake Filter

This vehicle is equipped with an air inlet restriction indicator. Service the filter elements when the air inlet restriction indicator locks in the extreme Up position. Paper elements require care and proper handling because they are critical to engine service life. If your vehicle has an external air cleaner and cab-mounted mirrors, the mirror must be pivoted to provide access for servicing the filter element.

Cooling System Maintenance

Your engines cooling system is standard with Extended Life Coolant (ELC). ELC consists of a mixture of ethylene glycol, water, and organic acid technology chemical inhibitors. ELC prevents corrosion and scale formation as well as provides freezing and boiling point protection.

CAUTION The engine cooling system has very specific maintenance and inspection requirements. Failure to follow re- quirements can damage the engine. Engine damage can include but is not limited to:

Freezing

Boiling

Corrosion

Pitted cylinder liners

This information is found in the en- ginemanufacturers owners manual. It is the owners responsibility to fol- low all requirements listed in the en- ginemanufacturers owners manual.

STOPPING THE ENGINE

Proper Coolant Level

NOTE Do not overfill a cooling system. Ex- cess coolant may result in overflow, loss of antifreeze, and reduced cor- rosion protection.

The minimum fluid level is determined by the line on the surge tank indicated by the letters MIN. This indicator is located below the fill cap.

The cooling system will need fluid if the surge tank level does not rise to the MIN line regardless if the system is hot or cold.

Topping Off

WARNING! Removing the fill cap on a hot en- gine can cause scalding coolant to spray out and burn you badly. If the engine has been in opera- tion within the previous 30 minutes, be very careful in removing the fill cap. Protect face, hands, and arms against escaping fluid and steam by covering the cap with a large, thick rag. Do not try to remove it until the surge tank cools down or if you see any steam or coolant escaping. In any situation, remove the cap very slowly and carefully. Be ready to back off if any steam or coolant be- gins to escape.

NOTE If frequent topping off is necessary and there are no visible signs of coolant leaks when the engine is cold, check for leaks with the engine operating at normal temperature.

Top off the cooling system when coolant does not rise to the level indicated as MIN on the surge tank. The surge tank is translucent which allows the coolant level to be seen. Add coolant through the surge tank fill cap. Do not remove the pressure cap to fill the cooling system.

(03/17) Y53-6076-1B1 4-57

STOPPING THE ENGINE

Surge Tank

NOTE Do not use the pressure cap to fill the surge tank with fluid.

Power Steering

Oil (under low pressure) provides the power to operate the steering gear. It also serves to lubricate moving parts and remove heat. A loss of steering efficiency will occur if too much heat builds up in the system.

WARNING! Do not operate the vehicle if the steering system is not working prop- erly. You could lose control of your vehicle if the steering system is not in good working condition, which could result in a serious accident. For driving safety, visually check the steering gear and components. Frequent checks are important for driving safety, especially after trav- eling over rough roads. Failure to comply may result in death, per- sonal injury, equipment or property damage.

CAUTION When adding fluid, be sure to use fluid of the same type. While many fluids have the same description and intended purpose, they should not be mixed due to incompatible ad- ditives. Mixing incompatible fluids may lead to equipment damage.

NOTE Before removing reservoir cover, wipe outside of cover so that no dirt can fall into the reservoir.

Maximum/Minimum level is indicated on the reservoir. These same levels are also indicated by two lines on the dipstick in the reservoir.

There are two ways to check whether the power steering fluid is at its proper level. Both checks are with the engine NOT running.

4-58 Y53-6076-1B1 (03/17)

STOPPING THE ENGINE

1. If you check the fluid with the engine and steering system COLD, the fluid level should be at/or above the Minimum indicator level and should generally not exceed the middle point between Maximum and Minimum level indicators.

2. If you check the fluid with the engine and steering system WARM, the fluid should NOT exceed the Maximum level indicator and should generally not drop below the middle point between the Maximum and Minimum level indicators.

Automatic Transmission Oil Level

NOTE The vehicle must be parked on level ground.

See the Transmission Operator's Manual for information on checking the transmission oil level.

Clutch Adjustment - Normal Wear

Clutch pedal free travel is usually 1 3/4 in. to 2 in. (34 to 51 mm). This should be your guide for determining whether your truck needs clutch adjustment. Also, if it becomes increasingly difficult to shift into gears, or the truck creeps with the clutch pedal depressed, your clutch needs adjustment. See the Maintenance Manual for the proper adjustment procedures.

Some vehicles have automatic clutch adjustment. If yours doesn't have this feature, adjustment will have to be done by a trained certified mechanic. Have the adjustment done before clutch pedal free travel is reduced to the minimum allowable 1/2 in. (13 mm).

STOPPING THE ENGINE

Fuse Inspection and Replacement

If a fuse is blown, see What to do if fuse or relay blows on page 2-6 for more information.

Wheel Cap Nut Torque

After the vehicle travels about 50 to 100 miles (80 to 160 km), wheel mountings seat in and will lose some initial torque. Check hub/wheel mountings after this initial period and retighten, see the Maintenance and Consumer Information Manual for sequence and specifications.
