Protection of the environment

General notes

H Environmental note Daimler's declared policy is one of compre- hensive environmental protection. The objectives are for the natural resources that form the basis of our existence on this planet to be used sparingly and in a manner that takes the requirements of both nature and humanity into account. You too can help to protect the environment by operating your vehicle in an environmen- tally responsible manner. Fuel consumption and the rate of engine, transmission, brake and tire wear are affected by these factors: Roperating conditions of your vehicle Ryour personal driving style You can influence both factors. You should bear the following in mind: Operating conditions: Ravoid short trips as these increase fuel con- sumption. Ralways make sure that the tire pressures are correct. Rdo not carry any unnecessary weight. Rremove roof racks once you no longer need them. Ra regularly serviced vehicle will contribute to environmental protection. You should therefore adhere to the service intervals. Ralways have service work carried out at a qualified specialist workshop.

Personal driving style: Rdo not depress the accelerator pedal when starting the engine. Rdo notwarmup the enginewhen the vehicle is stationary. Rdrive carefully and maintain a safe distance from the vehicle in front. Ravoid frequent, sudden acceleration and braking.

Rchange gear in good time and use each gear only up to of its maximum engine speed. Rswitch off the engine in stationary traffic. Rkeep an eye on the vehicle's fuel consump- tion.

H Environmental note Have a defective high-voltage battery dis- posed of in an environmentally-responsible manner. Contact a qualified specialist work- shop which has the necessary specialist knowledge and tools to carry out the work required. Mercedes-Benz recommends that you use an authorized Mercedes-Benz Center for this purpose.

Environmental concerns and recom- mendations Wherever the operating instructions require you to dispose of materials, first try to regen- erate or re-use them. Observe the relevant environmental rules and regulations when disposing of materials. In this way you will help to protect the environment.

Operating safety

Important safety notes

G WARNING If you do not have the prescribed service/ maintenance work or any required repairs

carried out, this can result in malfunctions or system failures. There is a risk of an accident. Always have the prescribed service/mainte- nance work as well as any required repairs carried out at a qualified specialist workshop.

G WARNING Flammable material such as leaves, grass or twigsmay ignite if they come into contactwith hot parts of the exhaust system. There is a risk of fire. When driving off road or on unpaved roads, check the vehicle's underside regularly. In particular, remove parts of plants or other flammable materials which have become trapped. In the case of damage, contact a qualified specialist workshop.

G WARNING Modifications to electronic components, their software as well as wiring can impair their function and/or the function of other net- worked components. In particular, systems relevant to safety could also be affected. As a result, these may no longer function as inten- ded and/or jeopardize the operating safety of the vehicle. There is an increased risk of an accident and injury. Never tamper with the wiring as well as elec- tronic components or their software. You should have all work to electrical and elec- tronic equipment carried out at a qualified specialist workshop.

If you make any changes to the vehicle elec- tronics, the general operating permit is ren- dered invalid.

! There is a risk of damage to the vehicle if: Rthe vehicle becomes stuck, e.g. on a high curb or an unpaved road Ryou drive too fast over an obstacle, e.g. a curb or a hole in the road Ra heavy object strikes the undercarriage or parts of the chassis

Introduction 27

Z

In situations like this, the body, the under- carriage, chassis parts, wheels or tires could be damaged without the damage being visible. Components damaged in this way can unexpectedly fail or, in the case of an accident, no longer withstand the strain they are designed to. If the underbody paneling is damaged, combustible materials such as leaves, grass or twigs can gather between the underbody and the underbody paneling. If these materials come in contact with hot parts of the exhaust system, they can catch fire. In such situations, have the vehicle checked and repaired immediately at a qualified specialist workshop. If on con- tinuing your journey you notice that driving safety is impaired, pull over and stop the vehicle immediately, paying attention to road and traffic conditions. In such cases, consult a qualified specialist workshop.

Hybrid vehicles have a combustion engine and an electric motor. The voltage supply for operating the vehicle electrically is provided by the vehicle's high-voltage electrical sys- tem.

G DANGER The vehicle's high voltage electrical system is under high voltage. If you modify components in the vehicle's high-voltage electrical system or touch damaged components, you may be electrocuted. The components in the vehi- cle's high-voltage electrical system may be damaged in an accident, although the damage is not visible. There is a risk of fatal injury. Following an accident, do not touch any high- voltage components and never modify the vehicle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system checked by a qualified specialist workshop.

The components of the vehicle's high-voltage electrical system are marked with yellow warning stickers. The cables of the vehicle's

high-voltage electrical system are orange in color. Vehicles with an electric motor generate much less driving noise than vehicles with internal combustion engines. As a result, your vehicle may not be heard by other road users in certain situations. This can happen, for example, when you are parking and your vehi- cle is not seen by other road users. This requires you to adopt a particularly anticipa- tory driving style, as it is necessary to allow for the possibility that other road users may behave erratically.

Declarations of conformity

You can also obtain other information about motor vehicle safety from http://www.safercar.gov

Limited Warranty ! Follow the instructions in this manual about the proper operation of your vehicle as well as about possible vehicle damage. Damage to your vehicle that arises from culpable contraventions against these instructions is not covered either by the Mercedes-Benz Limited Warranty or by the New or Used-Vehicle Warranty.

QR codes for the rescue card

The QR code is secured in the fuel filler flap and on the opposite side on the B-pillar. In the event of an accident, rescue services can use the QR code to quickly find the appropriate rescue card for your vehicle. The current res- cue card contains the most important infor- mation about your vehicle in a compact form, e.g. the routing of the electric cables. You can find more information at https:// portal.aftersales.i.daimler.com.

Data stored in the vehicle

Data recording This vehicle is capable of recording diagnostic information relating to vehicle operation,mal- functions, and user settings. This may include information about the performance or status of various systems, including but not limited to, engine, throttle, steering or brake sys- tems, that is stored and can be read out with suitable devices, particularly when the vehi- cle is serviced. The data obtained is used to properly diagnose and service your vehicle or to further optimize and develop vehicle func- tions.

COMAND/mbrace If the vehicle is equipped with COMAND or mbrace, additional data about the vehicles operation, the use of the vehicle in certain situations, and the location of the vehiclemay be compiled through COMAND or thembrace system. For additional information please refer to the COMAND User Manual and/or the mbrace Terms and Conditions.

Event data recorders This vehicle is equipped with an event data recorder (EDR). The main purpose of an EDR

30 Introduction

is to record data that will assist in under- standing how a vehicles systems performed in certain crash or near crash-like situations, such as during air bag deployment or when hitting a road obstacle. The EDR is designed to record data related to vehicle dynamics and safety systems for a short period of time, typically 30 seconds or less. The EDR in this vehicle is designed to record such data as: Rhow various systems in your vehicle are operating Rwhether or not the driver and passenger seat belts are fastened Rhow far (if at all) the driver is depressing the accelerator and/or brake pedal and Rhow fast the vehicle is traveling This data can help provide a better under- standing of the circumstances in which crashes and injuries occur. NOTE: EDR data is recorded by your vehicle only if a non-trivial crash situation occurs; no data is recorded by the EDR under normal driving conditions and no personal data (e.g., name, gender, age, and crash location) are recorded. However, other parties, such as law enforcement, can combine the EDR data with the type of per- sonal identification data routinely acquired during a crash investigation. To read data recorded by an EDR, special equipment is required, and access to the vehi- cle or the EDR is needed. In addition to the vehicle manufacturer, other parties that have the special equipment, such as law enforce- ment, can read the information by accessing the vehicle or the EDR. EDR data may be used in civil and criminal matters as a tool in accident reconstruction, accident claims, and vehicle safety. Since the Crash Data Retrieval CDR tool that is used to extract data from the EDR is commercially available, Mercedes-Benz USA, LLC ("MBUSA") expressly disclaims any and all lia- bility arising from the extraction of this infor- mation by unauthorized Mercedes-Benz per- sonnel.

MBUSA will not share EDR data with others without the consent of the vehicle owners or, if the vehicle is leased, without the consent of the lessee. Exceptions to this representation include responses to subpoenas by law enforcement; by federal, state or local gov- ernment; in connection with or arising out of litigation involving MBUSA or its subsidiaries and affiliates; or, as required by law. Warning: The EDR is a component of the Restraint System Module. Tampering with, altering, modifying or removing the EDR com- ponent may result in a malfunction of the Restraint System Module and other systems. State laws or regulations regarding EDRs that conflict with federal regulation are pre-emp- ted. This means that in the event of such con- flict, the federal regulation governs. As of February 2013, 13 states have enacted laws relating to EDRs.

Useful information

i This Operator's Manual describes all models and all standard and optional equip- ment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-related systems and functions.

i Read the information on qualified special- ist workshops (Y page 29).

Hybrid vehicles

General notes Hybrid technology combines a fuel efficient internal combustion engine with a powerful electric motor.

Important safety notes

Danger of electric shock

G DANGER The vehicle's high voltage electrical system is under high voltage. If you modify components in the vehicle's high-voltage electrical system or touch damaged components, you may be electrocuted. The components in the vehi- cle's high-voltage electrical system may be damaged in an accident, although the damage is not visible. There is a risk of fatal injury. Following an accident, do not touch any high- voltage components and never modify the vehicle's high-voltage electrical system. Have the vehicle towed away after an accident and the vehicle's high-voltage electrical system checked by a qualified specialist workshop.

When towing a vehicle after an accident, be sure to observe the following sections: RTransporting the vehicle (Y page 437) RTowing the vehicle with the rear axle raised (Y page 437) RTowing a vehicle with both axles on the ground (Y page 436)

Read the safety instructions on towing and tow-starting (Y page 435).

All components of the hybrid system are marked with yellow warning stickers that warn you of the danger of high voltage. The cables of the vehicle's high-voltage electrical system are orange in color. The ignition must be switched off when car- rying out general tasks, such as adding washer fluid to the windshield washer system or checking the coolant level.

Automatic deactivation of the hybrid system

G DANGER If the restraint system is malfunctioning, indi- vidual restraint system components may be triggered unintentionally or might not be trig- gered at all in the event of an accident with a high rate of vehicle deceleration. This could affect Emergency Tensioning Devices or air bags, for example. The vehicle's high-voltage electrical systemmay also not be deactivated as intended in the event of an accident. You could suffer an electric shock if you touch the damaged components of the vehicle's high-

46 Hybrid vehicles Sa fe ty

voltage electrical system. This poses an increased risk of injury or even fatal injury. Have the restraint system checked and repaired immediately at a qualified specialist workshop. Immediately switch off the ignition and remove the SmartKey from the ignition lock after an accident.

If components of the restraint system are activated during an accident, the hybrid sys- tem is automatically deactivated. The hybrid system is not activated when the vehicle is started if: Ra short circuit is detected in the hybrid sys- tem. Rone of the hybrid systems electrical con- nections is disconnected.

This ensures that you do not come into con- tact with high voltage.

Occupant safety

Restraint system: introduction The restraint system reduces the risk of vehi- cle occupants coming into contact with parts of the vehicle's interior in the event of an accident. The restraint system can also reduce the forces to which vehicle occupants are subjected during an accident. The restraint system comprises: RSeat belt system RAir bags RChild restraint system RChild seat securing systems

The components of the restraint systemwork in conjunction with each other. They can only deploy their protective function if, at all times, all vehicle occupants: Rhave fastened their seat belts correctly (Y page 53) Rhave adjusted their seat and head restraint properly (Y page 121).

As the driver, you also have to make sure that the steering wheel is adjusted correctly. Observe the information relating to the cor- rect driver's seat position (Y page 120). You also have tomake sure that an air bag can inflate properly if deployed (Y page 56). An air bag supplements a correctly worn seat belt. As an additional safety device, the air bag increases the level of protection for vehi- cle occupants in the event of an accident. For example, if, in the event of an accident, the protection offered by the seat belt is suffi- cient, the air bags are not deployed. When an accident occurs, only the air bags that increase protection in that particular accident situation are deployed. However, seat belts and air bags generally do not protect against objects penetrating the vehicle from the out- side. Information on restraint system operation can be found under "Deployment of Emer- gency Tensioning Devices and air bags" (Y page 65). For more information about children traveling with you in the vehicle and on child restraint systems, see "Children in the vehicle" (Y page 69).

Important safety notes

G WARNING Modifications to the restraint system may cause it to no longer work as intended. The restraint system may then not perform its intended protective function andmay fail in an accident or trigger unexpectedly, for example.

Restraint system warning lamp The functions of the restraint system are checked after the ignition is switched on and at regular intervals while the engine is run- ning. Therefore, malfunctions can be detec- ted in good time. The 6 restraint system warning lamp in the instrument cluster lights upwhen the igni- tion is switched on. It goes out no later than a few seconds after the vehicle is started. The components of the restraint system are in operational readiness. A malfunction has occurred if the 6 restraint system warning lamp: Rdoes not light up after the ignition is switched on Rdoes not go out after a few seconds with the engine running Rlights up again while the engine is running All vehicles, except hybrid vehicles:

G WARNING If restraint system is malfunctioning, restraint system components may be triggered unin- tentionally or might not be triggered at all in the event of an accident with a high rate of vehicle deceleration. This can affect the Emer- gency Tensioning Device or air bag, for exam- ple. This poses an increased risk of injury or even fatal injury.

Have the restraint system checked and repaired in a qualified specialist workshop as soon as possible.

Hybrid vehicles:

G DANGER If the restraint system is malfunctioning, indi- vidual restraint system components may be triggered unintentionally or might not be trig- gered at all in the event of an accident with a high rate of vehicle deceleration. This could affect Emergency Tensioning Devices or air bags, for example. The vehicle's high-voltage electrical systemmay also not be deactivated as intended in the event of an accident. You could suffer an electric shock if you touch the damaged components of the vehicle's high- voltage electrical system. This poses an increased risk of injury or even fatal injury. Have the restraint system checked and repaired immediately at a qualified specialist workshop. Immediately switch off the ignition and remove the SmartKey from the ignition lock after an accident.

ted. It will then not be deployed in the event of an accident. RPASSENGER AIR BAG ON; lights up: the front-passenger front air bag is enabled. If, in the event of an accident, all deployment criteria are met, the front-passenger front air bag is deployed.

Depending on the person in the front- passenger seat, the front-passenger front air bag must either be deactivated or enabled; see the following points. You must make sure of this both before and during a journey. RChildren in a child restraint system: whether the front-passenger front air bag is enabled or deactivated depends on the installed child restraint system, and the age and size of the child. Therefore, be sure to observe the notes on the "Occupant Clas- sification System (OCS)" (Y page 59) and on "Children in the vehicle" (Y page 69). There youwill also find instructions on rear- ward and forward-facing child restraint sys- tems on the front-passenger seat. RAll other persons: depending on the clas- sification of the person in the front- passenger seat, the front-passenger front air bag is enabled or deactivated (Y page 59). Be sure to observe the notes on "Seat belts (Y page 51) and "Air bags" (Y page 56). There you can also find infor- mation on the correct seat position.

Seat belts

Introduction Seat belts are the most effective means of restricting the movement of vehicle occu- pants in the event of an accident or the vehi- cle rolling over. This reduces the risk of vehi- cle occupants coming into contact with parts of the vehicle interior or being ejected from the vehicle. Furthermore, the seat belt helps to keep the vehicle occupant in the best posi- tion in relation to the air bag.

The seat belt system comprises: RSeat belts REmergency Tensioning Devices for the front seat belts and the outer seat belts in the rear RSeat belt force limiters for the front seat belts and the outer seat belts in the rear RBelt bags for the outer seat belts in the rear, depending on the vehicle's equipment

If the seat belt is pulled out of the belt outlet quickly or with a jerky movement, the belt retractor locks. The belt strap cannot be extracted any further. The Emergency Tensioning Device tightens the seat belt in an accident, pulling the belt close against the body. However it does not pull the vehicle occupant back in the direction of the backrest. The Emergency Tensioning Device does not correct an incorrect seat position or the rout- ing of an incorrectly fastened seat belt. When triggered, seat belt force limiters help to reduce the force exerted by the seat belt on the vehicle occupant. The seat belt force limiters for the front seats are synchronized with the front air bags, which absorb part of the deceleration force. This can reduce the force exerted on the vehi- cle occupants during an accident.

! If the front-passenger seat is unoccupied, do not insert the belt tongue into the buckle of the front-passenger seat. This may oth- erwise lead to the triggering of the Emer- gency Tensioning Device in the event of an accident, which will then need to be replaced.

Important safety notes The use of seat belts and child restraint sys- tems is required by law in: Rall 50 states Rthe U.S. territories Rthe District of Columbia Rall Canadian provinces

Even where this is not required by law, all vehicle occupants should correctly fasten their seat belts before starting the journey.

G WARNING If the seat belt is incorrectly fastened, it can- not protect as intended. Furthermore, an incorrectly fastened seat belt can cause addi- tional injury, for example, in an accident, dur- ing braking or when abruptly changing direc- tion. This poses an increased risk of injury or even fatal injury. Make sure that all vehicle occupants are seated properly with a correctly fastened seat belt.

G WARNING The seat belt does not offer the intended level of protection if you have not moved the back- rest to an almost vertical position. When brak- ing or in the event of an accident, you could slide underneath the seat belt and sustain abdomen or neck injuries, for example. This poses an increased risk of injury or even fatal injury. Adjust the seat properly before beginning your journey. Always ensure that the backrest is in an almost vertical position and that the shoulder section of your seat belt is routed across the center of your shoulder.

G WARNING Objects next to the front seat that block the belt buckle or the moving belt anchorage on the front seat impair the function of the Emer- gency Tensioning Devices. The Emergency Tensioning Devicesmay not function as inten- ded and the seat belt may no longer provide the intended protection. This poses an increased risk of injury or even fatal injury. Before starting the journey, make sure that there are no objects around the belt buckle or between the front seat and door.

G WARNING Persons under 5 ft (1.50 m) in height cannot fasten the seat belt correctly without an addi-

tional suitable restraint system. If the seat belt is incorrectly fastened, it cannot protect as intended. Furthermore, an incorrectly fas- tened seat belt can cause additional injury, for example, in an accident, during braking or an abrupt change of direction. This poses an increased risk of injury or even fatal injury. For this reason, always secure persons under 5 ft (1.50 m) in height in suitable restraint systems.

If a child younger than 12 years and under 5 ft (1.50 m) in height is traveling in the vehicle: Ralways secure the child in a child restraint system suitable for this Mercedes-Benz vehicle. The child restraint system must be appropriate to the age, weight and size of the child Ralways observe the instructions and safety notes on the belt bags for the outer seat belts in the rear (Y page 53) Ralways observe the instructions and safety notes in the "Children in the vehicle" sec- tion of this Operator's Manual (Y page 69) in addition to the child restraint system manufacturer's installa- tion instructions Rbe sure to observe the instructions and safety notes on the "Occupant classifica- tion system (OCS)" (Y page 59)

G WARNING The seat belts may not perform their intended protective function if: Rthey are damaged, modified, extremely dirty, bleach or dyed Rthe seat belt buckle is damaged or extremely dirty Rthe Emergency Tensioning Devices, belt anchorages or inertia reels have beenmodi- fied

Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi- fied or damaged seat belts may tear or fail, e.g. in an accident. Modified Emergency Ten- sioning Devices could accidentally trigger or

52 Occupant safety Sa fe ty

fail to deploy when necessary. This poses an increased risk of injury or even fatal injury. Never modify the seat belts, Emergency Ten- sioning Devices, belt anchorages or inertia reels. Make sure that the seat belts are undamaged, not worn out and clean. Follow- ing an accident, have the seat belts checked immediately at a qualified specialist work- shop.

Only use seat belts that have been approved for your vehicle by Mercedes-Benz. Any such modifications could invalidate the vehicle's general operating permit.

Proper use of the seat belts Observe the safety notes on the seat belt (Y page 51). All vehicle occupants must be wearing the seat belt correctly before beginning the jour- ney. Also make sure that all vehicle occu- pants are always wearing the seat belt cor- rectly while the vehicle is in motion. When fastening the seat belt, always make sure that: Rthe seat belt tongue is only inserted to the belt buckle belonging to that seat. Rthe seat belt is tight across your body. Avoid wearing bulky clothing, e.g. a winter coat. Rthe seat belt is not twisted. Only then can the forces which occur be distributed over the area of the belt. Rthe shoulder section of the belt is always routed across the center of your shoulder. The shoulder section of the belt must not come into contact with your neck or be routed under your arm. Where possible, adjust the seat belt to the appropriate height. Rthe lap belt passes tightly and as low down as possible across your lap. The lap belt must always be routed across your hip joints and not across your abdo- men. This applies particularly to pregnant

women. If necessary, push the lap belt down to your hip joint and pull it tight using the shoulder section of the belt. Rthe seat belt is not routed across sharp, pointed or fragile objects. If you have such items located on or in your clothing, e.g. pens, keys or eyeglasses, store these in a suitable place. Ronly one person is using a seat belt at a time. Infants and children must never travel sit- ting on the lap of a vehicle occupant. In the event of an accident, they could be crushed between the vehicle occupant and seat belt. Robjects are never secured with a seat belt if the seat belt is also being used by one of the vehicle's occupants.

Seat belts are only intended to secure and restrain vehicle occupants. Always observe the "Loading guidelines" for securing objects, luggage or loads (Y page 372).

Rear beltbags

i Observe the "Important safety notes" sec- tion (Y page 56).

Depending on the vehicle's equipment, the outer rear seat belts are equipped with a belt bag. This can be seen from the BELTBAG iden- tification on the rear seat belt.

G WARNING In an accident, the belt bag may damage a non-approved child restraint system. As a result, the child restraint system may not be able to provide the intended level of protec- tion. This poses an increased risk of injury or even fatal injury. For this reason, a child restraint system with an integrated seat belt should always be installed using LATCH-type (ISOFIX). In a vehi- cle with optional belt bags for the rear seats, you should only ever use a booster seat with integrated backrest that has been tested and approved by Mercedes-Benz in conjunction

Rear seat belt buckle extenders The seat belt extender is an integral part of the PRE-SAFE convenience function. It is used on the outer rear seats. Always ensure that it is possible to move the belt buckle freely. Always stow objects in the vehicle correctly. To assist you in finding the seat belt buckle and fastening the seat belt: Rthe belt buckle moves forwards to a con- venient position Rthe belt buckle is illuminated After the seat belt is fastened, the belt buckle returns to its normal position. The seat belt then lies tight across the lap and thorax areas. Incorporation into the PRE-SAFE system: the belt buckle is lowered quickly in certain hazardous situations. This pre-tensions the seat belt. Incorporation into the automatic meas- ures after the accident: in this situation, the belt buckle is illuminated and extended after a rear door is opened.

Releasing seat belts

! Make sure that the seat belt is fully rolled up. Otherwise, the seat belt or belt tongue will be trapped in the door or in the seat mechanism. This could damage the door, the door trim panel and the seat belt. Dam- aged seat belts can no longer fulfill their protective function and must be replaced. Visit a qualified specialist workshop.

X Press release button:, hold belt tongue; firmly and guide it back towards belt outlet=.

Seat belt adjustment The seat-belt adjustment is an integral part of the PRE-SAFE convenience function. This function adjusts the driver's and front- passenger seat belt to the upper body of the occupants. The belt strap is tightened slightly when: Rthe belt tongue is engaged in the buckle and Rthe ignition is switched on The seat-belt adjustment will apply a certain retraction force if any slack is detected between the vehicle occupant and the seat belt. Do not hold on to the seat belt tightly while it is adjusting. You can switch the seat-belt adjustment on and off using COMAND. Information on switching the belt adjustment function on and off can be found in the Digital Operator's Manual or in the separateCOMANDoperating instructions.

Belt warning for the driver and front passenger The7 seat belt warning lamp in the instru- ment cluster is a reminder that all occupants must fasten their seat belts. It may light up continuously or flash. In addition, there may be a warning tone. Regardless of whether the driver's seat belt has already been fastened, the7 seat belt warning lamp lights up for six seconds each time the engine is started. If, after six seconds, the driver or front-passenger seat belt has not been fastened and the doors are closed, the 7 seat belt warning lamp lights up. As soon as the driver's and front- passenger seat belts are fastened or a front door is opened again, the 7 seat belt warning lamp goes out. If the driver's seat belt is not fastened after the engine is started, an additional warning tone will sound. This warning tone stops after six seconds or when the driver's seat belt is fastened. If the vehicle's speed exceeds 15 mph (25 km/h) once and the driver's and front- passenger seat belts are not fastened, a warning tone sounds. A warning tone also sounds with increasing intensity for 60 seconds or until the driver or front passenger have fastened their seat belts. If the driver or front passenger unfasten their seat belts during the journey, the seat belt warning is activated again.

i For more information on the 7 seat belt warning lamp, see "Warning and indi- cator lamps in the instrument cluster, seat belts" (Y page 355).

Air bags

Introduction The installation point of an air bag can be rec- ognized by the AIR BAG symbol. An air bag complements the correctly fas- tened seat belt. It is no substitute for the seat

belt. The air bag provides additional protec- tion in applicable accident situations. Not all air bags are deployed in an accident. The different air bag systems function inde- pendently from one another (Y page 65). However, no system available today can com- pletely eliminate injuries and fatalities. It is also not possible to rule out a risk of injury caused by an air bag due to the high speed at which the air bag must be deployed.

Important safety notes

G WARNING If you do not sit in the correct seat position, the air bag cannot protect as intended and could even cause additional injury when deployed. This poses an increased risk of injury or even fatal injury. To avoid hazardous situations, always make sure that all of the vehicle's occupants: Rhave fastened their seat belts correctly, including pregnant women Rare sitting correctly andmaintain the great- est possible distance to the air bags Rfollow the following instructions Always make sure that there are no objects between the air bag and the vehicle's occu- pants.

RAdjust the seats properly before beginning your journey. Always make sure that the seat is in an almost upright position. The center of the head restraint must support the head at about eye level. RMove the driver's and front-passenger seats as far back as possible. The driver's seat position must allow the vehicle to be driven safely. ROnly hold the steering wheel on the out- side. This allows the air bag to be fully deployed. RAlways lean against the backrest while driv- ing. Do not lean forwards or lean against the door or side window. You may other-

56 Occupant safety Sa fe ty

wise be in the deployment area of the air bags. RAlways keep your feet in the footwell in front of the seat. Do not put your feet on the dashboard, for example. Your feet may oth- erwise be in the deployment area of the air bag. RFor this reason, always secure persons less than 5 ft (1.50 m) tall in suitable restraint systems. Up to this height, the seat belt cannot be worn correctly.

If a child is traveling in your vehicle, also observe the following notes: RAlways secure children under 12 years of age and less than 5 ft (1.50 m) in height in suitable child restraint systems. RChild restraint systems should be installed on the rear seats. ROnly secure a child in a rearward-facing child restraint system on the front- passenger seat when the front-passenger front air bag is deactivated. If the PASSENGER AIR BAGOFF indicator lamp is permanently lit, the front-passenger front air bag is deactivated (Y page 50). RAlways observe the instructions and safety notes on the "Occupant Classification Sys- tem (OCS)" (Y page 59) and on "Children in the vehicle" (Y page 69) in addition to the child restraint system manufacturer's installation instructions.

Objects in the vehicle interior may pre- vent an air bag from functioning correctly. Before starting your journey and to avoid risks resulting from the speed of the air bag as it deploys, make sure that: Rthere are no people, animals or objects between the vehicle occupants and an air bag. Rthere are no objects between the seat, door and B-pillar. Rno hard objects, e.g. coat hangers, hang on the grab handles or coat hooks. Rno accessories, such as cup holders, are attached to the vehicle within the deploy-

ment area of an air bag, e.g. to doors, side windows, rear side trim or side walls. Rno heavy, sharp-edged or fragile objects are in the pockets of your clothing. Store such objects in a suitable place.

G WARNING If you modify the air bag cover or affix objects such as stickers to it, the air bag can no longer function correctly. There is an increased risk of injury. Never modify an air bag cover or affix objects to it.

G WARNING Sensors to control the air bags are located in the doors. Modifications or work not per- formed correctly to the doors or door panel- ing, as well as damaged doors, can lead to the function of the sensors being impaired. The air bags might therefore not function properly any more. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. There is an increased risk of injury. Never modify the doors or parts of the doors. Always have work on the doors or door pan- eling carried out at a qualified specialist work- shop.

When deployed, the front air bags offer addi- tional head and thorax protection for the occupants in the front seats. The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps inform you about the status of the front- passenger front air bag (Y page 50). Front-passenger front air bag; will only deploy if: Rthe system, based on the OCS weight sen- sor readings, detects that the front- passenger seat is occupied (Y page 59). The PASSENGER AIR BAG ON indicator lamp is lit (Y page 60) Rthe restraint system control unit predicts a high accident severity

Driver's knee bag

Driver's knee bag: deploys under the steer- ing column. The driver's knee bag is always deployed along with the driver's front air bag. The driver's knee bag offers additional thigh, knee and lower leg protection for the occu- pant in the driver's seat.

Side impact air bags

G WARNING Unsuitable seat covers could restrict or even prevent the deployment of the air bags inte- grated into the seats. Consequently, the air bags cannot protect vehicle occupants as they are designed to do. In addition, the func- tion of the Occupant Classification System

(OCS) could be restricted. This poses an increased risk of injury or even fatal injury. You should only use seat covers that have been approved for the respective seat by Mercedes-Benz.

Front side impact air bags: and rear side impact air bags; deploy next to the outer bolster of the seat backrest. When deployed, the side impact air bag offers additional thorax protection. It also offers additional pelvis protection for occupants in the front seats. However, it does not protect the: Rhead Rneck Rarms In the event of a side impact, the side impact air bag is deployed on the side on which the impact occurs. The side impact air bag on the front- passenger side (front) deploys in the follow- ing situations: Rthe OCS system detects that the front- passenger seat is occupied or Rthe belt tongue is engaged in the belt buckle of the front-passenger seat

If the belt tongue is engaged in the belt buckle, the side impact air bag on the front- passenger side deploys if an appropriate acci- dent situation occurs. In this case, deploy- ment is independent of whether the front- passenger seat is occupied or not.

58 Occupant safety Sa fe ty

Window curtain air bags

Window curtain air bags: are integrated into the side of the roof frame and deployed in the area from the A-pillar to the C-pillar. When deployed, the window curtain air bag enhances the level of protection for the head. However, it does not protect the chest or arms. In the event of a side impact, the window cur- tain air bag is deployed on the side on which the impact occurs. If the system determines that they can offer additional protection to that provided by the seat belt, a window curtain air bag may be deployed in other accident situations (Y page 65).

Cushion air bags

i Observe the "Important safety notes" sec- tion (Y page 56).

The rear reclining seat is equipped with a cushion air bag. If the seat backrest is reclined, the cushion air bag can provide addi- tional occupant protection in the event of frontal collision situations. When triggered, the cushion air bag deploys under the seat cushion. This helps prevent the occupant from slipping off the seat cushion.

G WARNING If a child restraint system is installed and the seat backrest is reclined too far backwards, the cushion air bag may deploy by mistake in the event of an accident. There is an increased risk of injury.

When using a child restraint system, always ensure that the seat is correctly adjusted and that the backrest is almost vertical.

If you install a child restraint system on the rear reclining seat, always observe: Rthe instructions and safety notes in "Chil- dren in the vehicle" (Y page 69) Rthe child restraint system manufacturer's installation instructions.

Occupant Classification System (OCS)

Introduction The Occupant Classification System (OCS) categorizes the person in the front-passenger seat. Depending on that result, the front- passenger front air bag is either enabled or deactivated. The system does not deactivate: Rthe side impact air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices

Prerequisites To be classified correctly, the front passenger must sit: Rwith the seat belt fastened correctly Rin an almost upright position with their back against the seat backrest Rwith their feet resting on the floor, if possi- ble

If the front passenger does not observe these conditions, OCS may produce a false classi- fication, e.g. because the front passenger: Rtransfers their weight by supporting them- selves on a vehicle armrest Rsits in such a way that their weight is raised from the seat cushion

If it is absolutely necessary to install a child restraint system on the front-passenger seat, be sure to observe the correct positioning of

the child restraint system. Never place objects under or behind the child restraint system, e.g. cushions. Fully retract the seat cushion length. The entire base of the child restraint systemmust always rest on the seat cushion of the front-passenger seat. The backrest of the forwards-facing child restraint systemmust, as far as possible, be resting on the backrest of the front-passenger seat. The child restraint systemmust not touch the roof or be put under strain by the head restraint. Adjust the angle of the seat back- rest and the head restraint position accord- ingly. Only then can OCS be guaranteed to function correctly. Always observe the child restraint system manufacturer's installation instruc- tions.

If the status of the front-passenger front air bag changes while the vehicle is in motion, an air bag displaymessage appears in the instru- ment cluster (Y page 332). When the front- passenger seat is occupied, always pay atten- tion to the PASSENGER AIR BAG ON and PASSENGERAIRBAGOFF indicator lamps. Be aware of the status of the front-passenger front air bag both before and during the jour- ney.

G WARNING If the PASSENGER AIR BAG OFF indicator lamp is lit, the front-passenger front air bag is disabled. It will not be deployed in the event of an accident and cannot perform its intended protective function. A person in the front- passenger seat could then, for example, come into contact with the vehicle's interior, espe- cially if the person is sitting too close to the dashboard. This poses an increased risk of injury or even fatal injury. When the front-passenger seat is occupied, always ensure that: Rthe classification of the person in the front- passenger seat is correct and the front- passenger front air bag is enabled or disa- bled in accordance with the person in the front-passenger seat Rthe front-passenger seat has been moved back as far back as possible. Rthe person is seated correctly. Make sure, both before and during the jour- ney, that the status of the front-passenger front air bag is correct.

G WARNING If you secure a child in a rearward-facing child restraint system on the front-passenger seat and the PASSENGER AIR BAG ON indicator lamp is lit up, the front-passenger front air bag may deploy in an accident. The child could be struck by the air bag. This poses an increased risk of injury or even fatal injury. Make sure that the front-passenger front air bag has been disabled. The PASSENGER AIR BAG OFF indicator lamp must be lit.

If the PASSENGER AIR BAG OFF indicator lamp remains off and/or the PASSENGER AIR BAGON indicator lamp lights up, do not install a rearward-facing child restraint system on the front-passenger seat. You can find more information on OCS under "Problemswith the Occupant Classification System" (Y page 64).

G WARNING If you secure a child in a forward-facing child restraint system on the front-passenger seat and you position the front-passenger seat too close to the dashboard, in the event of an accident, the child could: Rcome into contact with the vehicle's inte- rior if the PASSENGER AIR BAG OFF indi- cator lamp is lit, for example Rbe struck by the air bag if the PASSENGER AIR BAG ON is lit up

This poses an increased risk of injury or even fatal injury. Always move the front-passenger seat as far back as possible and fully retract the seat cushion length. Always make sure that the shoulder belt strap is correctly routed from the vehicle belt sash guide to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed forwards and downwards from the vehicle belt sash guide. If necessary, adjust the vehicle belt sash guide and the front-passenger seat accordingly. Always observe the child restraint system manufacturer's installation instructions.

If OCS determines that: Rthe front-passenger seat is unoccupied, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indicates that the front- passenger front air bag is deactivated. Rthe front-passenger seat is occupied by a child of up to 12 months old in a standard child restraint system, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indi- cates that the front-passenger front air bag is deactivated. But in the case of a 12-month-old child in a standard child restraint system, the PASSENGER AIR BAG ON can light up per- manently after the system self-test. This indicates that the front-passenger front air bag is activated. The result of the classifi- cation is dependent on, among other fac- tors, the child restraint system and the child's stature. It is recommended that you install the child restraint system on a suit- able rear seat. Rthe front-passenger seat is occupied by a person of smaller stature (e.g. a teenager or small adult), either the PASSENGER AIR BAG ON or PASSENGER AIR BAG OFF indi- cator lamp lights up and remains lit after the system self-test depending on the result of the classification. - If the PASSENGER AIR BAG ON indicator lamp lights up, move the front-passenger seat as far back as possible. Alterna- tively, a person of smaller stature can sit on a rear seat.

- If the PASSENGERAIR BAGOFF indicator lamp is lit, a person of smaller stature should not use the front-passenger seat.

Rthe front-passenger seat is occupied by an adult or a person of a stature correspond- ing to that of an adult, the PASSENGER AIR BAG ON indicator lamp lights up after the system self-test and remains lit. This indi- cates that the front-passenger front air bag is activated.

If children are traveling in the vehicle, be sure to observe the notes on "Children in the vehi- cle" (Y page 69). When OCS is malfunctioning, the red 6 restraint system warning lamp in the instru- ment cluster and the PASSENGER AIR BAG OFF indicator lamp light up simultaneously. The front-passenger front air bag is deactiva- ted in this case and does not deploy during an accident. Have the system checked by quali- fied technicians as soon as possible. Consult an authorized Mercedes-Benz Center. The front-passenger seat should only be repaired at an authorized Mercedes-Benz Center. If the front-passenger seat, the seat cover or the seat cushion is damaged, have the nec- essary repair work carried out at an author- ized Mercedes-Benz Center. For safety reasons, Mercedes-Benz recom- mends that you only use seat accessories that have been approved by Mercedes-Benz. If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy. The Occupant Classification System (OCS) categorizes the occupant in the front-passenger seat. Depending on that result, the front-passenger front air bag is either enabled or deactivated.

System self-test

G DANGER If both the PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps do not light up during the system self-test, the system is malfunctioning. The front- passenger front air bag might be triggered unintentionally or might not be triggered at all in the event of an accident with high deceler- ation. This poses an increased risk of injury or even fatal injury. In this case the front-passenger seat may not be used. Do not install a child restraint system on the front-passenger seat. Have the Occu- pant Classification System (OCS) checked and repaired immediately at a qualified spe- cialist workshop.

G DANGER If the PASSENGER AIR BAG OFF indicator lamp remains lit after the system self-test, the front-passenger front air bag is disabled. It will not be deployed in the event of an accident. In this case, the front-passenger front air bag cannot perform its intended protective func- tion, e.g. when a person is seated in the front- passenger seat. That person could, for example, come into contact with the vehicle's interior, especially if the person is sitting too close to the dash- board. This poses an increased risk of injury or even fatal injury. When the front-passenger seat is occupied, always ensure that: Rthe classification of the person in the front- passenger seat is correct and the front- passenger front air bag is enabled or disa- bled in accordance with the person in the front-passenger seat Rthe person is seated properly with a cor- rectly fastened seatbelt Rthe front-passenger seat has been moved back as far back as possible

If the PASSENGER AIR BAG OFF indicator lamp remains lit when it should not, the front- passenger seat may not be used. Do not install a child restraint system on the front- passenger seat. Have the Occupant Classifi- cation System (OCS) checked and repaired immediately at a qualified specialist work- shop.

G WARNING Objects between the seat surface and the child restraint system could affect OCS oper- ation. This could result in the front-passenger air bag not functioning as intended during an accident. This poses an increased risk of injury or even fatal injury. Do not place any objects between the seat surface and the child restraint system. The entire base of the child restraint system must always rest on the seat cushion of the front- passenger seat. The backrest of the forward-

Deployment of Emergency Tensioning Devices and air bags

Important safety notes

G WARNING The air bag parts are hot after an air bag has been deployed. There is a risk of injury. Do not touch the air bag parts. Have a deployed air bag replaced at a qualified spe- cialist workshop as soon as possible.

G WARNING A deployed air bag no longer offers any pro- tection and cannot provide the intended pro- tection in an accident. There is an increased risk of injury. Have the vehicle towed to a qualified special- ist workshop in order to have a deployed air bag replaced.

It is important for your safety and that of your passenger to have deployed air bags replaced and to have any malfunctioning air bags repaired. This will help to make sure the air bags continue to perform their protective function for the vehicle occupants in the event of a crash.

G WARNING Pyrotechnic Emergency Tensioning Devices that have been deployed are no longer opera- tional and are unable to perform their inten- ded protective function. This poses an increased risk of injury or even fatal injury. Therefore, have pyrotechnic Emergency Ten- sioning Devices which have been triggered immediately replaced at a qualified specialist workshop.

An electric motor is used by PRE-SAFE to trigger the tightening of the seat belt in haz- ardous situations. This procedure is reversi- ble. If Emergency Tensioning Devices are trig- gered or air bags are deployed, you will hear a bang, and a small amount of powder may also

be released. The 6 restraint system warn- ing lamp lights up. Only in rare cases will the bang affect your hearing. The powder that is released gener- ally does not constitute a health hazard, but it may cause short-term breathing difficulties in people with asthma or other respiratory prob- lems. To avoid this, youmay wish to get out of the vehicle or open the windows as soon as it is safe to do so. Air bags and pyrotechnic Emergency Tension- ing Devices (ETDs) contain perchlorate mate- rial, which may require special handling and regard for the environment. National guide- lines must be observed during disposal. In California, see www.dtsc.ca.gov/ HazardousWaste/Perchlorate/ index.cfm.

Method of operation During the first stage of a collision, the restraint system control unit evaluates impor- tant physical data relating to vehicle deceler- ation or acceleration, such as: Rduration Rdirection Rintensity Based on the evaluation of this data, the restraint system control unit triggers the Emergency Tensioning Devices during a fron- tal or rear collision. An Emergency Tensioning Device can only be triggered, if: Rthe ignition is switched on Rthe components of the restraint system are operational; see "Restraint system warning lamp" (Y page 50) Rthe belt tongue is engaged in the buckle on the respective front-passenger seat

The Emergency Tensioning Devices in the rear compartment are triggered independ- ently of the lock status of the seat belts.

Occupant safety 65

Sa fe ty

Z

Vehicles with belt bags: the belt bags are also deployed depending on the type and severity of the accident. Vehicles with a rear reclining seat: the Emergency Tensioning Device is only trig- gered if the belt buckle tongue is engaged in the belt buckle. If the seat backrest is reclined, the cushion air bag will also be deployed depending on the type and severity of the accident. If the restraint system control unit detects a more severe accident, further components of the restraint system are activated independ- ently of each other in certain frontal collision situations: RFront air bags and driver's knee bag RWindow curtain air bag, if the system deter- mines that deployment can offer additional protection to that provided by the seat belt

The front-passenger front air bag is activated or deactivated depending on the person on the front-passenger seat. The front- passenger front air bag can only deploy in an accident if the PASSENGER AIR BAG ON indi- cator lamp is lit. Observe the information on the PASSENGER AIR BAG indicator lamps (Y page 50). Your vehicle has two-stage front air bags. During the first deployment stage, the front air bag is filled with propellant gas to reduce the risk of injuries. The front air bag is fully deployed with the maximum amount of pro- pellant gas if a second deployment threshold is reached within a few milliseconds. The activation threshold of the Emergency Tensioning Devices and the air bag are deter- mined by evaluating the rate of vehicle decel- eration or acceleration which occurs at vari- ous points in the vehicle. This process is pre- emptive in nature. Deployment should take place in good time at the start of the collision.

The rate of vehicle deceleration or accelera- tion and the direction of the force are essen- tially determined by: Rthe distribution of forces during the colli- sion Rthe collision angle Rthe deformation characteristics of the vehi- cle Rthe characteristics of the object with which the vehicle has collided

Factorswhich can only be seen andmeasured after a collision has occurred do not play a decisive role in the deployment of an air bag. Nor do they provide an indication of air bag deployment. The vehicle can be deformed considerably, without an air bag being deployed. This is the case if only parts which are relatively easily deformed are affected and the rate of decel- eration is not high. Conversely, air bags may be deployed even though the vehicle suffers only minor deformation. This is the case if, for example, very rigid vehicle parts such as lon- gitudinal bodymembers are hit, and sufficient deceleration occurs as a result. If the restraint system control unit detects a side impact or that the vehicle is rolling over, the relevant restraint system components are activated independently of one another depending on the apparent type of accident. If the systemdetermines a need for additional protection for the vehicle occupants, the Emergency Tensioning Devices are triggered. RSide impact air bags on the side of impact, independently of the Emergency Tension- ing Device and the use of the seat belt on the driver's seat and outer seats in the sec- ond row

66 Occupant safety Sa fe ty

The side impact air bag on the front- passenger side (front) deploys in the fol- lowing situations: - the OCS system detects that the front- passenger seat is occupied or

- the belt tongue is engaged in the belt buckle of the front-passenger seat

RWindow curtain air bag on the side of impact, independently of the use of the seat belt and independently of whether the front-passenger seat is occupied RWindow curtain air bags on the driver's and front-passenger side in certain situations when the vehicle rolls over, if the system determines that deployment can offer addi- tional protection to that provided by the seat belt

i Not all air bags are deployed in an acci- dent. The different air bag systems work independently of each other. How the air bag system works is deter- mined by the severity of the accident detec- ted, especially the vehicle deceleration or acceleration and the apparent type of acci- dent: Rfrontal collision Rside impact Rrollover

PRE-SAFE (anticipatory occupant protection system)

Introduction

In certain hazardous situations, PRE-SAFE takes pre-emptive measures to protect the vehicle occupants.

Important safety notes

! Make sure that there are no objects in the footwell under or behind the seats when moving the seats back. There is a risk that the seats and/or the objects could be dam- aged.

Despite your vehicle being equipped with the PRE-SAFE system, the possibility of per- sonal injuries occurring as a result of an acci- dent cannot be eliminated. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe dis- tance from the vehicle in front. Drive care- fully.

Function

PRE-SAFE intervenes: Rin emergency braking situations, e.g. when BAS is activated Rin critical driving situations, e.g. when phys- ical limits are exceeded and the vehicle understeers or oversteers severely Rvehicles with the Driving Assistance pack- age: when a driver assistance system inter- venes powerfully or the radar sensor sys- tem detects an imminent danger of colli- sion in certain situations

PRE-SAFE takes the following measures depending on the hazardous situation detec- ted: Rthe front seat belts are pre-tensioned. Rif the vehicle skids, the panorama roof with power tilt/sliding panel and the side win- dows are closed so that only a small gap remains. Rthe front-passenger seat is adjusted if it is in an unfavorable position. Rfor vehicles with electrically adjustable rear seats: the outer rear seats are adjusted if they are in an unfavorable position. Rvehicles with a multicontour seat: the air pressure in the side bolsters of the seat backrest is increased. Rvehicles with seat belt extenders: the seat belts of the outer rear seats are pre-ten- sioned.

If the hazardous situation passes without resulting in an accident, PRE-SAFE slackens the belt pre-tensioning. On vehicles with mul- ticontour seats, the air pressure in the side

bolsters is reduced again. All settings made by PRE-SAFE can then be reversed. If the seat belt pre-tensioning is not reduced: X Move the seat backrest or seat back slightly when the vehicle is stationary. The seat belt pre-tensioning is reduced and the locking mechanism is released.

The seat-belt adjustment is an integral part of the PRE-SAFE convenience function. Infor- mation about the convenience function can be found under "Belt adjustment" (Y page 55).

PRE-SAFE PLUS (anticipatory occu- pant protection system PLUS)

Introduction

PRE-SAFE PLUS is only available in vehicles with the Driving Assistance package. Using the radar sensor system, PRE-SAFE PLUS is able to detect that a head-on or rear- end collision is imminent. In certain hazard- ous situations, PRE-SAFE PLUS takes pre- emptive measures to protect the vehicle occupants.

Important safety notes

The intervention of PRE-SAFE PLUS cannot prevent an imminent collision. The driver is not warned when PRE-SAFE PLUS intervenes. PRE-SAFE PLUS does not intervene if the vehicle is backing up. PRE-SAFE PLUS does not perform braking actions while the vehicle is in motion or when Parking Guidance is active.

Function

PRE-SAFE PLUS intervenes in certain situa- tions if the radar sensor system detects an imminent head-on or rear-end collision.

PRE-SAFE PLUS takes the following meas- ures depending on the hazardous situation detected: Rif the radar sensor system detects that a head-on collision is imminent, the seat belts are pre-tensioned. Rif the radar sensor system detects that a rear-end collision is imminent: - the brake pressure is increased if the driver applies the brakes when the vehi- cle is stationary.

- the seat belts are pre-tensioned. The PRE-SAFE PLUS braking application is canceled: Rif the accelerator pedal is depressed when a gear is engaged Rif the risk of a collision passes or is no lon- ger detected Rif DISTRONIC PLUS indicates an intention to pull away

If the hazardous situation passes without resulting in an accident, the original settings are restored.

Automatic measures after an acci- dent Immediately after an accident, the following measures are implemented, depending on the type and severity of the impact: Rthe hazard warning lamps are activated Rthe emergency lighting is activated Rthe vehicle doors are unlocked Rthe front side windows are lowered Rthe electrically adjustable steering wheel is raised Rthe engine is switched off and the fuel sup- ply is cut off Rvehicles with seat belt extenders: the seat- belt buckles for the outer rear seats are illuminated and extend forwards

Rvehicles with mbrace: automatic emer- gency call Rvehicles with the hybrid drive system: the hybrid system and the high-voltage electri- cal system are deactivated

Children in the vehicle

Important safety notes Accident statistics show that children secured in the rear seats are safer than chil- dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat. Children are generally better pro- tected there. If a child younger than 12 years and under 5 ft (1.50 m) in height is traveling in the vehicle: Ralways secure the child in a child restraint system suitable for Mercedes-Benz vehi- cles. The child restraint system must be appropriate to the age, weight and size of the child Rbe sure to observe the instructions and safety notes in this section in addition to the child restraint system manufacturer's installation instructions Rbe sure to observe the instructions and safety notes on the "Occupant classifica- tion system (OCS)" (Y page 59)

G WARNING If you leave children unsupervised in the vehi- cle, they could set it inmotion by, for example: Rrelease the parking brake. Rshift the automatic transmission out of the parking position P. Rstart the engine. In addition, they may operate vehicle equip- ment and become trapped. There is a risk of an accident and injury. When leaving the vehicle, always take the SmartKeywith you and lock the vehicle. Never leave children unsupervised in the vehicle.

G WARNING If persons, particularly children are subjected to prolonged exposure to extreme heat or cold, there is a risk of injury, possibly even fatal. Never leave children unattended in the vehicle.

G WARNING If the child restraint system is subjected to direct sunlight, parts may get very hot. Chil- dren may burn themselves on these parts, particularly on the metal parts of the child restraint system. There is a risk of injury. If you leave the vehicle, taking the child with you, always ensure that the child restraint system is not exposed to direct sunlight. Pro- tect it with a blanket, for example. If the child restraint system has been exposed to direct sunlight, let it cool down before securing the child in it. Never leave children unattended in the vehicle.

Always ensure that all vehicle occupants have their seat belts fastened correctly and are sit- ting properly. Particular attention must be paid to children. Observe the safety notes on the seat belt (Y page 51) and the notes on correct use of seat belts (Y page 53). A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lbs (18 kg) or until they reach a height where a lap/shoulder belt can be fastened properly without a booster seat.

Special seat belt retractor

G WARNING If the seat belt is released while driving, the child restraint system will no longer be secured properly. The special seat belt retrac- tor is disabled and the inertia real draws in a portion of the seat belt. The seat belt cannot be immediately refastened. There is an increased risk of injury, possibly even fatal.

Stop the vehicle immediately, paying atten- tion to road and traffic conditions. Reactivate the special seat belt retractor and secure the child restraint system properly.

All seat belts except the driver's seat belt are equipped with a special seat belt retractor. When activated, the special seat belt retrac- tor ensures that the seat belt will not slacken once the child restraint system has been secured. Installing a child restraint system: X Always comply with the child restraint sys- tem manufacturer's installation instruc- tions.

X Pull the seat belt smoothly from the belt outlet.

X Engage the seat belt tongue in the belt buckle.

Activating the special seat belt retractor: X Pull the seat belt out fully and let the inertia reel retract it again. While the seat belt is retracting, you should hear a ratcheting sound. The special seat belt retractor is activated.

X Push the child seat restraint system down so that the seat belt is tight and does not loosen.

Removing a child restraint system/deactivat- ing the special seat belt retractor: X Always comply with the child restraint sys- tem manufacturer's installation instruc- tions.

X Press the release button on the belt buckle, hold the belt tongue firmly and guide it back towards the belt outlet. The special seat belt retractor is deactiva- ted.

Child restraint system The use of seat belts and child restraint sys- tems is required by law in: Rall 50 states Rthe U.S. territories Rthe District of Columbia Rall Canadian provinces You can obtain further information about the correct child restraint system from any authorized Mercedes-Benz Center.

G WARNING If the child restraint system is installed incor- rectly on a suitable seat, it cannot protect as intended. The child cannot then be restrained in the event of an accident, heavy braking or sudden changes of direction. There is an increased risk of injury, possibly even fatal. Make sure that you observe the child restraint system manufacturer's installation instruc- tions and the notes on use. Please ensure, that the base of the child restraint system is always resting completely on the seat cush- ion. Never place objects, e.g. cushions, under or behind the child restraint system. Only use child restraint systems with the original cover designed for them. Only replace damaged covers with genuine covers.

G WARNING If the child restraint system is installed incor- rectly or is not secured, it can come loose in the event of an accident, heavy braking or a sudden change in direction. The child restraint system could be thrown about, strik- ing vehicle occupants. There is an increased risk of injury, possibly even fatal. Always install child restraint systems prop- erly, even if they are not being used. Make sure that you observe the child restraint sys- tem manufacturer's installation instructions.

You will find further information on stowing objects, luggage or loads under "Loading guidelines" (Y page 372).

G WARNING Child restraint systems or their securing sys- tems which have been damaged or subjected to a load in an accident can no longer protect as intended. The child cannot then be restrained in the event of an accident, heavy braking or sudden changes of direction. There is an increased risk of injury, possibly even fatal. Replace child restraint systems which have been damaged or subjected to a load in an accident as soon as possible. Have the secur- ing systems on the child restraint system checked at a qualified specialist workshop, before you install a child restraint system again.

The securing systems of child restraint sys- tems are: Rthe seat belt system Rthe LATCH-type (ISOFIX) securing rings Rthe Top Tether anchorages If it is absolutely necessary to carry a child on the front-passenger seat, be sure to observe the information on the "Occupant Classifica- tion System (OCS)" (Y page 59). There you will also find information on deactivating the front-passenger front air bag. All child restraint systems must meet the fol- lowing standards: RU.S. Federal Motor Vehicle Safety Stand- ards 213 and 225 RCanadian Motor Vehicle Safety Standards 213 and 210.2

Confirmation that the child restraint system corresponds to the standards can be found on an instruction label on the child restraint system. This confirmation can also be found in the installation instructions that are inclu- ded with the child restraint system. Observe thewarning labels in the vehicle inte- rior and on the child restraint system.

Vehicles with seat belt extenders: when securing a child in a child restraint system on a rear seat, observe the following instruc- tions: Rmake sure that the seat belt on the child restraint system is fastened according to the manufacturer's installation instruc- tions for the child restraint system. Rfor child restraint systems with a belt clamp: engage the belt tongue in the buckle before you tighten the seat belt using the belt clamp.

Vehicles with a rear reclining seat: when installing a child restraint system, move the rear reclining seat backrest to an almost ver- tical position. The rear reclining seat backrest must rest against the child restraint system. Observe the notes on the cushion air bag (Y page 59). Vehicles with belt bags: only use a child restraint system which has been approved by Mercedes-Benz. Always observe the instruc- tions and safety notes on belt bags for the outer seat belts in the rear (Y page 53).

LATCH-type (ISOFIX) child seat secur- ing system

G WARNING LATCH-type (ISOFIX) child restraint systems do not offer sufficient protective effect for children whose weight is greater than 48 lbs (22 kg) who are secured using the safety belt integrated in the child restraint system. In the event of an accident, a child might not be restrained correctly. This poses an increased risk of injury or even fatal injury. If the child weighs more than 48 lbs (22 kg), only use LATCH-type (ISOFIX) child restraint systems with which the child is also secured with the vehicle seat belt. Also secure the child restraint system with the Top Tether belt, if available.

X Vehicleswith a rear reclining seat:move the rear reclining seat backrest to an upright position. The rear reclining seat

backrest must rest against the child restraint system.

G WARNING Vehicles with electrically adjustable rear bench seats: If you adjust the seat after installing a child restraint system: Rthe seat belt could slacken or become too tight Rthe child restraint system could become loose, incorrectly positioned or damaged

As a result, the child restraint systemmay not be able to provide the intended level of pro- tection. This poses an increased risk of injury or even fatal injury. Never adjust the seat after installing the child restraint system.

Vehicles without rear reclining seat: after you have removed the LATCH-type (ISOFIX) child restraint system, you must turn the sup- port on the rear side of upholstered lining: by 90 again. Then fold upholstery lining: down. ISOFIX is a standardized securing system for specially designed child restraint systems on the rear seats. LATCH-type (ISOFIX) securing rings; for two LATCH-type (ISOFIX) child restraint systems are installed on the left and right rear seats. Vehicles with rear seat armrest: adjust the rear seat armrest so that LATCH-type (ISO- FIX) securing rings; for the LATCH-type (ISOFIX) child restraint system are accessi- ble. Non-LATCH-type (ISOFIX) child seats may also be used and can be installed using the vehicle's seat belt system. Install the child seat according to the manufacturer's instruc- tions.

Top Tether

Introduction Top Tether provides an additional connection between the child restraint system secured with a LATCH-type (ISOFIX) child seat mount and the vehicle. This helps reduce the risk of injury even further. If the child restraint sys- tem is equipped with a Top Tether belt, this should always be used.

Important safety notes

G WARNING If the rear seat backrests are not locked, they could fold forwards in the event of an acci- dent, heavy braking or sudden changes of direction. As a result, child restraint systems cannot perform their intended protective function. Rear seat backrests that are not locked can also cause additional injuries, e.g. in the event of an accident. This poses an increased risk of injury or even fatal injury. Always lock rear seat backrests after instal- ling a Top Tether belt. Observe the lock veri- fication indicator. Adjust the rear seat backr- ests so that they are in an upright position.

G WARNING Vehicles with electrically adjustable rear bench seats: If you adjust the seat after installing a child restraint system: Rthe seat belt could slacken or become too tight Rthe child restraint system could become loose, incorrectly positioned or damaged

As a result, the child restraint systemmay not be able to provide the intended level of pro- tection. This poses an increased risk of injury or even fatal injury. Never adjust the seat after installing the child restraint system.

Child restraint system on the front- passenger seat

General notes Accident statistics show that children secured in the rear seats are safer than chil- dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises that you install the child restraint system on a rear seat. If it is absolutely necessary to install a child restraint system on the front-passenger seat, be sure to observe the instructions and safety notes on the "OccupantClassificationSystem (OCS)" (Y page 59). You can thus avoid the risks that could arise as a result of: Ran incorrectly categorized person in the front-passenger seat Rthe unintentional deactivation of the front- passenger front air bag Rthe unsuitable positioning of the child restraint system, e.g. too close to the dash- board

Rearward-facing child restraint system If it is absolutely necessary to install a rear- ward-facing child restraint system on the front-passenger seat, always make sure that the front-passenger front air bag is deactiva- ted. Only if the PASSENGER AIR BAG OFF indicator lamp is permanently lit (Y page 50) is the front-passenger front air bag deactiva- ted.

Always observe the child restraint system manufacturer's installation and operating instructions.

Forward-facing child restraint system If it is absolutely necessary to install a forward-facing child restraint system on the front-passenger seat, always move the front- passenger seat as far back as possible. Fully retract the seat cushion length. The entire base of the child restraint system must always rest on the seat cushion of the front- passenger seat. The backrest of the child restraint system must lie as flat as possible against the backrest of the front-passenger seat. The child restraint system must not touch the roof or be subjected to a load by the head restraint. Adjust the angle of the seat backrest and the head restraint position accordingly. Alwaysmake sure that the shoul- der belt strap is correctly routed from the vehicle belt outlet to the shoulder belt guide on the child restraint system. The shoulder belt strapmust be routed forwards and down- wards from the vehicle belt outlet. If neces- sary, adjust the vehicle belt outlet and the front-passenger seat accordingly. Always observe the child restraint system manufacturer's installation and operating instructions.

Driving safety systems

Overview of driving safety systems In this section, you will find information about the following driving safety systems: RABS (Anti-lock Braking System) (Y page 76) RBAS (Brake Assist System) (Y page 77) RBASPLUS (BrakeAssistSystemPLUS)with Cross-Traffic Assist (Y page 77)

RCOLLISION PREVENTION ASSIST PLUS (distance warning function and Adaptive Brake Assist) (Y page 79) RESP (Electronic Stability Program) (Y page 81) REBD (Electronic Brake force Distribution) (Y page 83) RADAPTIVE BRAKE (Y page 84) RPRE-SAFE Brake (Y page 84) RSTEER CONTROL (Y page 86)

Important safety notes If you fail to adapt your driving style or if you are inattentive, the driving safety systems can neither reduce the risk of an accident nor override the laws of physics. Driving safety systems are merely aids designed to assist driving. You are responsible for maintaining the distance to the vehicle in front, for vehicle speed, for braking in good time and for stay- ing in lane. Always adapt your driving style to suit the prevailing road and weather condi- tions and maintain a safe distance from the vehicle in front. Drive carefully. The driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Please pay special attention to the notes on tires, recommended minimum tire tread depths, etc. (Y page 442). Inwintry driving conditions, always usewinter tires (M+S tires) and if necessary, snow chains. Only in this way will the driving safety systems described in this section work as effectively as possible.

ABS (Anti-lock Braking System)

General information ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehi- cle when braking.

76 Driving safety systems Sa fe ty

The!ABSwarning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running.

Important safety notes

i Observe the "Important safety notes" sec- tion (Y page 76).

G WARNING If ABS is faulty, the wheels could lock when braking. The steerability and braking charac- teristics may be severely impaired. Addition- ally, further driving safety systems are deac- tivated. There is an increased danger of skid- ding and accidents. Drive on carefully. Have ABS checked imme- diately at a qualified specialist workshop.

When ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp (Y page 358) and display messages which may be shown in the instrument cluster (Y page 317). ABS works from a speed of about 5 mph (8 km/h), regardless of road-surface condi- tions. ABS works on slippery surfaces, even when you only brake gently.

Braking X If ABS intervenes: continue to depress the brake pedal vigorously until the braking sit- uation is over.

X To make a full brake application: depress the brake pedal with full force.

If ABS intervenes when braking, you will feel a pulsing in the brake pedal. The pulsating brake pedal can be an indica- tion of hazardous road conditions, and func- tions as a reminder to take extra care while driving.

BAS (Brake Assist System)

General information BAS operates in emergency braking situa- tions. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance.

Important safety notes

i Observe the "Important safety notes" sec- tion (Y page 76).

G WARNING If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident. In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking.

Braking X Keep the brake pedal firmly depressed until the emergency braking situation is over. ABS prevents the wheels from locking.

The brakes will function as usual once you release the brake pedal. BAS is deactivated.

BAS PLUS (Brake Assist System PLUS) with Cross-Traffic Assist

General information

i Observe the "Important safety notes" sec- tion (Y page 76).

BAS PLUS is only available on vehicles with the Driving Assistance package. For BAS PLUS to assist you when driving, the radar sensor system and the camera system must be operational. With the help of a sensor system and a cam- era system, BAS PLUS can detect obstacles: Rthat are in the path of your vehicle for an extended period of time Rthat cross the path of your vehicle

Driving safety systems 77

Sa fe ty

Z

In addition, pedestrians in the path of your vehicle can be detected. BAS PLUS detects pedestrians by using typi- cal characteristics such as the body contours and posture of a person standing upright. If the radar sensor system or the camera sys- tem is malfunctioning, BAS PLUS functions are restricted or no longer available. The brake system is still available with complete brake boosting effect and BAS.

i Observe the restrictions described in the "Important safety notes" sec- tion (Y page 78).

BAS PLUS can help you tominimize the risk of a collision with a vehicle or a pedestrian and reduce the effects of such a collision. If BAS PLUS detects a danger of collision, you are assisted when braking.

Important safety notes

G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. In such cases, BAS PLUS may: Rintervene unnecessarily Rnot intervene There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the intervention in a non-critical driving situation.

G WARNING BAS PLUS does not react: Rto small people, e.g. children Rto animals Rto oncoming vehicles Rwhen cornering As a result, BAS PLUSmay not intervene in all critical situations. There is a risk of an acci- dent. Always pay careful attention to the traffic sit- uation and be ready to brake.

In the event of snowfall or heavy rain, the rec- ognition can be impaired. Recognition by the radar sensor system is also impaired in the event of: Rthere is dirt on the sensors or anything else covering the sensors Rthere is interference by other radar sources Rthere are strong radar reflections, for example in parking garages Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line Rvehicles quickly moving into the radar sen- sor system detection range

Recognition by the camera system is also impaired in the event of: Rdirt on the camera or if the camera is cov- ered Rthere is glare on the camera system, e.g. from the sun being low in the sky Rdarkness Rif:

- pedestrians move quickly, e.g. into the path of the vehicle

- the camera system no longer recognizes a pedestrian as a person due to special clothing or other objects

- a pedestrian is concealed by other objects

- the typical outline of a person is not dis- tinguishable from the background

Following damage to the front end of the vehi- cle, have the configuration and operation of the radar sensors checked at a qualified spe- cialist workshop. This also applies to colli- sions at low speeds where there is no visible damage to the front of the vehicle. Following damage to the windshield, have the configuration and operation of the camera systemchecked at a qualified specialist work- shop.

78 Driving safety systems Sa fe ty

Function To avoid a collision, BAS PLUS calculates the brake force necessary if: Ryou approach an obstacle, and RBAS PLUS has detected a risk of collision When driving at a speed under 20 mph (30 km/h): if you depress the brake pedal, BAS PLUS is activated. The increase in brake pressure will be carried out at the last possi- ble moment. When driving at a speed above 20 mph (30 km/h): if you depress the brake pedal sharply, BAS PLUS automatically raises the brake pressure to a value adapted to the traf- fic situation. BAS PLUS provides braking assistance in haz- ardous situations with vehicles in front within a speed range between 4 mph (7 km/h) and 155 mph (250 km/h). At speeds of up to approximately 44 mph (70 km/h), BAS PLUS can react to: Rstationary objects in the path of your vehi- cle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle Robjects crossing your path and that are recognized in the detection range of the sensors

i If BAS PLUS demands particularly high braking force, preventative passenger pro- tection measures (PRE-SAFE) are activa- ted simultaneously.

X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking.

BAS PLUS is deactivated and the brakes func- tion as usual again, if: Ryou release the brake pedal. Rthere is no longer a risk of collision. Rno obstacle is detected in front of your vehicle. Ryou depress the accelerator pedal. Ryou activate kickdown.

COLLISION PREVENTION ASSIST PLUS

General information COLLISION PREVENTION ASSIST PLUS con- sists of a distance warning function with an autonomous braking function and adaptive Brake Assist. COLLISION PREVENTION ASSIST PLUS can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If COLLISION PREVENTION ASSIST PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. If you do not react to the visual and audible collision warning, autonomous braking can be initiated in critical situations. If you apply the brake yourself in a critical situation, the COLLISION PREVENTION ASSIST PLUS adaptive Brake Assist assists you.

Important safety notes In particular, the detection of obstacles can be impaired if: Rthere is dirt on the sensors or anything else covering the sensors Rthere is snow or heavy rain Rthere is interference by other radar sources Rthere are strong radar reflections, for example in parking garages Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line Rnew vehicles or after a service on the COL- LISION PREVENTION ASSIST PLUS system Observe the notes in the section on break- ing-in (Y page 188).

Following damage to the front end of the vehi- cle, have the configuration and operation of the radar sensor checked at a qualified spe- cialist workshop. This also applies to colli- sions at low speeds where there is no visible damage to the front of the vehicle.

Distance warning function

Important safety notes i Observe the "Important safety notes" sec- tion for driving safety systems (Y page 76).

G WARNING The distance warning function does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering Thus, the distance warning function cannot provide a warning in all critical situations. There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake.

G WARNING The distance warning function cannot always clearly identify objects and complex traffic situations. In such cases, the distance warning function may: Rgive an unnecessary warning Rnot give a warning There is a risk of an accident. Always pay careful attention to the traffic sit- uation and do not rely solely on the distance warning function.

Function X To activate/deactivate: activate or deac- tivate the distance warning function in the on-board computer (Y page 309).

If the distance warning function is not activa- ted, the symbol appears in the assis- tance graphics display. The distancewarning function can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If the distance warning function detects that there is a risk of a collision, you will be warned visually and acoustically.

Starting at a speed of around 4mph (7 km/h), the distance warning function warns you if you rapidly approach a vehicle in front. An intermittent warning tone will then sound, and the distance warning lamp will light up in the instrument cluster. X Brake immediately in order to increase the distance from the vehicle in front.

or X Take evasive action, provided it is safe to do so.

Due to the nature of the system, particularly complicated but non-critical driving condi- tions may also cause the system to display a warning. With the help of the radar sensor system, the distance warning function can detect obsta- cles that are in the path of your vehicle for an extended period of time. Up to a speed of around 44 mph (70 km/h), the distance warning function can also react to stationary obstacles, such as stopped or parked vehicles. If you approach an obstacle and the distance warning function detects a risk of a collision, the system will initially alert you both visually and acoustically.

Autonomous braking function If the driver does not react to the distance warning signal in a critical situation, COLLI- SION PREVENTION ASSIST PLUS can assist with the autonomous braking function. The autonomous braking function: Rgives the driver more time to react to criti- cal driving situations Rcan help the driver to avoid an accident or Rreduces the effects of an accident The autonomous braking function is available in the following speed ranges: Rfrom 5 mph (7 km/h) to approx. 65 mph (105 km/h) for moving objects Rfrom 5 mph (7 km/h) to approx. 31 mph (50 km/h) for stationary objects

80 Driving safety systems Sa fe ty

If the autonomous braking function requires a particularly high braking force, preventative passenger protection measures (PRE-SAFE) are activated simultaneously.

Adaptive Brake Assist

i Observe the "Important safety notes" sec- tion (Y page 76).

Adaptive Brake Assist provides braking assis- tance in hazardous situations at speeds above 4 mph (7 km/h). It uses radar sensor technology to assess the traffic situation.

G WARNING Adaptive Brake Assist cannot always clearly identify objects and complex traffic situa- tions. In such cases, Adaptive Brake Assist can: Rintervene unnecessarily Rnot intervene There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the intervention in a non-critical driving situation.

G WARNING Adaptive Brake Assist does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering As a result, the Adaptive Brake Assist may not intervene in all critical conditions. There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake.

Due to the nature of the system, particularly complicated but non-critical driving condi- tions may also cause Brake Assist to inter- vene. If adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the

brake system remains available with full brake boosting effect and BAS. With the help of adaptive Brake Assist, the distance warning signal can detect obstacles that are in the path of your vehicle for an extended period of time. If adaptive Brake Assist detects a risk of col- lision with the vehicle in front, it calculates the braking force necessary to avoid a colli- sion. If you apply the brakes forcefully, adap- tive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions. X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking.

The brakes will work normally again if: Ryou release the brake pedal. Rthere is no longer any danger of a collision. Rno obstacle is detected in front of your vehicle.

Adaptive Brake Assist is then deactivated. If adaptive Brake Assist demands particularly high braking force, preventative passenger protection measures (PRE-SAFE) are activa- ted simultaneously. Up to a speed of approximately 155 mph (250 km/h), adaptive Brake Assist is capable of reacting to moving objects that have already been detected as such at least once over the period of observation. Up to a speed of approximately 44 mph (70 km/h), adaptive Brake Assist reacts to stationary obstacles.

ESP (Electronic Stability Program)

General notes

i Observe the "Important safety notes" sec- tion (Y page 76).

ESP monitors driving stability and traction, i.e. power transmission between the tires and the road surface.

Driving safety systems 81

Sa fe ty

Z

If ESP detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP assists the driver when pulling away on wet or slippery roads. ESP can also stabilize the vehicle during braking.

ETS/4ETS (Electronic Traction System)

i Observe the "Important safety notes" sec- tion (Y page 76).

ETS traction control is part of ESP. On vehi- cles with 4MATIC, 4ETS is part of ESP. Traction control brakes the drive wheels indi- vidually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on one side. In addition, more drive torque is trans- ferred to the wheel or wheels with traction. Traction control remains active, even if you deactivate ESP.

Important safety notes

G WARNING If ESP is malfunctioning, ESP is unable to stabilize the vehicle. Additionally, further driv- ing safety systems are deactivated. This increases the risk of skidding and an accident. Drive on carefully. Have ESP checked at a qualified specialist workshop.

Vehicles without 4MATIC: observe the notes on ESP (Y page 437) when towing the vehi- cle with a raised rear axle. ESP is only deactivated if the warning lamp is lit continuously. If the warning lamp lights up continu- ously, ESP is not available due to a malfunc- tion. Observe the information on warning lamps (Y page 360) and display messages which may be shown in the instrument cluster (Y page 317).

Only use wheels with the recommended tire sizes. Only then will ESP function properly.

Characteristics of ESP

General information If the ESP warning lamp goes out before beginning the journey, ESP is automatically active. If ESP intervenes, the ESP warning lamp flashes in the instrument cluster. If ESP intervenes: X Do not deactivate ESP under any circum- stances.

X Only depress the accelerator pedal as far as necessary when pulling away.

X Adapt your driving style to suit the prevail- ing road and weather conditions.

ECO start/stop function The ECO start/stop function switches the engine off automatically when the vehicle stops moving. The engine starts automati- callywhen the driverwants to pull away again. ESP remains in its previously selected sta- tus.Example: if ESPwas deactivated before the engine was switched off, ESP remains deactivated when the engine is switched on again.

Deactivating/activating ESP

Important safety notes i Observe the "Important safety notes" sec- tion (Y page 76).

You can select between the following states of ESP: RESP is activated. RESP is deactivated.

G WARNING If you deactivate ESP, ESP no longer sta- bilizes the vehicle. There is an increased risk of skidding and an accident.

82 Driving safety systems Sa fe ty

Only deactivate ESP in the situations descri- bed in the following.

It may be best to deactivate ESP in the fol- lowing situations: Rwhen using snow chains Rin deep snow Ron sand or gravel

i Activate ESP as soon as the situations described above no longer apply. ESP will otherwise not be able to stabilize the vehi- cle if the vehicle starts to skid or a wheel starts to spin.

! Avoid spinning the driven wheels for an extended period with ESP deactivated. You could otherwise damage the drivetrain.

Deactivating/activating ESP

You can deactivate or activate ESP via the on-board computer. X To deactivate: (Y page 82). The ESP OFF warning lamp in the instrument cluster lights up.

X To activate: (Y page 82). The ESP OFF warning lamp in the instrument cluster goes out.

Characteristics when ESP is deactivated If ESP is deactivated and one ormorewheels start to spin, the ESP warning lamp in the instrument cluster flashes. In such situa- tions, ESP will not stabilize the vehicle. If you deactivate ESP: RESP no longer improves driving stability. Rengine torque is no longer limited and the drive wheels are able to spin. The spinning of the wheels results in a cut- ting action for better traction on loose sur- faces. Rtraction control is still activated. RESP still provides support when you brake.

Crosswind Assist (vehicles without MAGIC BODY CONTROL)

General information Vehicles with MAGIC BODY CONTROL: infor- mation on stabilizing the vehicle in the event of crosswind (Y page 243). Strong crosswinds can cause your vehicle to deviate from a straight course. The crosswind driving assistance function integrated into ESP significantly reduces these effects. ESP intervenes automatically according to the direction and intensity of the crosswinds affecting your vehicle. ESP intervenes with stabilizing braking to assist you in keeping the vehicle in the lane. Crosswind Assist is active at vehicle speeds above 50 mph (80 km/h) when driving straight ahead or cornering gently.

Important safety notes Crosswind Assist does not work if ESP is deactivated or disabled because of a mal- function.

EBD (electronic brake force distribu- tion)

General information EBD monitors and controls the brake pres- sure on the rear wheels to improve driving stability while braking.

Important safety notes

i Observe the "Important safety notes" sec- tion (Y page 76).

G WARNING If EBD is malfunctioning, the rear wheels can lock, e.g. under full braking. This increases the risk of skidding and an accident. You should therefore adapt your driving style to the different handling characteristics. Have the brake system checked at a qualified spe- cialist workshop.

Observe information regarding indicator and warning lamps (Y page 358) as well as dis- play messages (Y page 320).

ADAPTIVE BRAKE ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addi- tion to the braking function, ADAPTIVEBRAKE also has the HOLD function (Y page 242) and hill start assist (Y page 192).

PRE-SAFE Brake

General information

i Pay attention to the important safety notes in the "Driving safety systems" sec- tion (Y page 76).

PRESAFE Brake is only available for vehi- cles with the Driving Assistance package. For PRE-SAFE Brake to assist you when driv- ing, the radar sensor system and the camera system must be switched on and be opera- tional. With the help of the radar sensor system and the camera system, PRE-SAFE Brake can detect obstacles that are in front of your vehi- cle for an extended period of time. In addition, pedestrians in the path of your vehicle can be detected. PRE-SAFE Brake detects pedestrians using typical characteristics such as the body con- tours and posture of a person standing upright. Observe the restrictions described in the "Important safety notes" sec- tion (Y page 84). PRE-SAFE Brake can help you to minimize the risk of a collision with a vehicle ahead or a pedestrian, and reduce the effects of such a collision. If PRE-SAFE Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic brak- ing.

Important safety notes

G WARNING PRE-SAFE Brake will initially brake your vehi- cle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you brake yourself. Even after subsequent full application of the brakes a collision cannot always be avoided, partic- ularly when approaching at too high a speed. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action, provided it is safe to do so.

G WARNING PRE-SAFE Brake cannot always clearly iden- tify objects and complex traffic conditions. In these cases, PRE-SAFE Brake may: Rgive an unnecessary warning and then brake the vehicle Rnot give a warning or intervene There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE Brake warns you. Terminate the intervention in a non-critical driving situation.

In order to maintain the appropriate distance to the vehicle in front and thus prevent a col- lision, you must apply the brakes yourself. PRE-SAFE Brake can also brake the vehicle automatically under the following conditions: Rthe driver and front-passenger have their seat belts fastened and Rthe vehicle speed is between approx- imately 4 mph (7 km/h) and 124 mph (200 km/h)

At a speed of up to approximately 44 mph (70 km/h), PRE-SAFEBrake can also detect: Rstationary objects in the path of your vehi- cle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle

84 Driving safety systems Sa fe ty

G WARNING PRE-SAFE Brake does not react: Rto small people, e.g. children Rto animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering As a result, PRE-SAFE Brake may neither give warnings nor intervene in all critical sit- uations. There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake.

In the event of snowfall or heavy rain, the rec- ognition can be impaired. Recognition by the radar sensor system is also impaired in the event of: Rthere is dirt on the sensors or anything else covering the sensors Rthere is interference by other radar sources Rthere are strong radar reflections, for example in parking garages Ra narrow vehicle traveling in front, e.g. a motorbike Ra vehicle traveling in front on a different line relative to the center of your vehicle

Recognition by the camera system is also impaired in the event of: Rdirt on the camera or if the camera is cov- ered Rthere is glare on the camera system, e.g. from the sun being low in the sky Rdarkness Rif:

- pedestrians move quickly, e.g. into the path of the vehicle

- the camera system no longer recognizes a pedestrian as a person due to special clothing or other objects

- a pedestrian is concealed by other objects

- the typical outline of a person is not dis- tinguishable from the background

Following damage to the front end of the vehi- cle, have the configuration and operation of the radar sensors checked at a qualified spe- cialist workshop. This also applies to colli- sions at low speeds where there is no visible damage to the front of the vehicle. Following damage to the windshield, have the configuration and operation of the camera systemchecked at a qualified specialist work- shop.

Function X To activate/deactivate: activate or deac- tivate PRE-SAFE Brake in the on-board computer (Y page 309). If the PRE-SAFEBrake is not activated, the symbol appears in the multifunction display.

Starting at a speed of around 4mph (7 km/h), this function warns you if you rapidly approach a vehicle in front. An intermittent warning tone will then sound and the distance warning lamp will light up in the instrument cluster. X Brake immediately to defuse the situation. or X Take evasive action provided it is safe to do so.

i If there is an increased risk of collision, preventive passenger protection measures (PRE-SAFE) are activated.

If the risk of collision with the vehicle in front remains and you do not brake, take evasive action or accelerate significantly, the vehicle may perform automatic emergency braking, up to the point of full brake application. Auto- matic emergency braking is not performed until immediately prior to an imminent acci- dent. You can prevent the intervention of the PRE- SAFE Brake at any time by: Rdepressing the accelerator pedal further. Ractivating kickdown. Rreleasing the brake pedal.

Useful information

i This Operator's Manual describes all models and all standard and optional equip- ment of your vehicle available at the time of publication of the Operator's Manual. Country-specific differences are possible. Please note that your vehicle may not be equipped with all features described. This also applies to safety-related systems and functions.

i Read the information on qualified special- ist workshops (Y page 29).

Exterior lighting

General notes For reasons of safety, Mercedes-Benz recom- mends that you drive with the lights switched on even during the daytime. In some coun- tries, operation of the headlamps varies due to legal requirements and self-imposed obli- gations.

Driving abroad

Symmetrical low-beam headlamps Switch the headlamps to symmetrical low beam in countries in which traffic drives on the opposite side of the road from the country where the vehicle is registered. This prevents glare to oncoming traffic. When using sym- metrical lights, the edge of the road is not lit as widely and as far ahead as normal. Have the headlamps converted at a qualified specialist workshop as close to the border as possible before driving in these countries.

Asymmetrical low beam Have the headlamps converted back to asym- metrical low-beam headlamps at a qualified specialist workshop as soon as possible after crossing the border again.

Setting the exterior lighting

Setting options Exterior lighting can be set using: Rthe light switch Rthe combination switch (Y page 152) Rthe on-board computer (Y page 312)

The automatic headlamp feature is only an aid. The driver is responsible for the vehicle's lighting at all times. Canada only: The daytime running lamps improve the visi- bility of your vehicle during the day. The day- time running lamps function is required by law inCanada. It cannot therefore be deactivated. When the engine is running and the vehicle is stationary: if youmove the selector lever from a drive position to P, the daytime running lamps/low-beam headlamps go out after three minutes. When the engine is running, the vehicle is stationary and in bright ambient light: if you turn the light switch to T, the daytime running lamps and parking lamps switch on. If the engine is running and you turn the light switch to L, the manual settings take precedence over the daytime running lamps. USA only: The daytime running lamps improve the visi- bility of your vehicle during the day. To do this, the daytime running lamps function must be switched on using the on-board computer (Y page 312). If the engine is running and you turn the light switch to T or L, the manual settings take precedence over the daytime running lamps. is the favored light switch setting. The light setting is automatically selected accord- ing to the brightness of the ambient light (exception: poor visibility due to weather con- ditions such as fog, snow or spray): RSmartKey in position 1 in the ignition lock: the parking lamps are switched on or off

automatically depending on the brightness of the ambient light. RWith the engine running: if you have acti- vated the "daytime running lamps" function via the on-board computer, the daytime running lamps or the parking lamps and the low-beamheadlamps are switched on or off automatically depending on the brightness of the ambient light.

X To switch on automatic headlamp mode: turn the light switch to.

Low-beam headlamps Even if the light sensor does not detect that it is dark, the parking lamps and low-beam headlamps switch on when the ignition is switched on and the light switch is set to the L position. This is a particularly useful function in the event of rain and fog. X To switch on the low-beam headlamps: turn the SmartKey in the ignition lock to position 2 or start the engine.

X Turn the light switch to L. The greenL indicator lamp in the instru- ment cluster lights up.

Parking lamps ! If the battery has been excessively dis- charged, the parking lamps or standing lamps are automatically switched off to enable the next engine start. Always park your vehicle safely and sufficiently lit according to legal standards. Avoid the continuous use of the T parking lamps for several hours. If possible, switch on the X right or the W left standing lamp.

X To switch on: turn the light switch toT. The greenT indicator lamp in the instru- ment cluster lights up.
