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.

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.

Genuine Mercedes-Benz parts

H Environmental note Daimler AG also supplies reconditionedmajor assemblies and parts which are of the same quality as new parts. They are covered by the same Limited Warranty entitlements as new parts.

! Air bags and Emergency Tensioning Devi- ces, as well as control units and sensors for these restraint systems, may be installed in the following areas of your vehicle: Rdoors Rdoor pillars Rdoor sills Rseats Rcockpit Rinstrument cluster Rcenter console Do not install accessories such as audio systems in these areas. Do not carry out repairs or welding. You could impair the operating efficiency of the restraint sys- tems. Have aftermarket accessories installed at a qualified specialist workshop.

You could jeopardize the operating safety of your vehicle if you use parts, tires and wheels as well as accessories relevant to safety which have not been approved by Mercedes. This could lead to malfunctions in safety-rel- evant systems, e.g. the brake system. Use only genuine Mercedes-Benz parts or parts of equal quality. Only use tires, wheels and accessories that have been specifically approved for your vehicle. Genuine Mercedes-Benz parts are subject to strict quality control. Every part has been spe- cifically developed, manufactured or selected for and adapted to Mercedes-Benz vehicles. Only genuine Mercedes-Benz parts should therefore be used. More than 300,000 different genuine Mercedes-Benz parts are available for Mercedes-Benz models.

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.

! 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

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

24 Introduction

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.

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 (Canada: TELEAID) 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 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.

Occupant safety

Introduction to the restraint system The restraint system can reduce the risk of vehicle 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 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 43) Rhave adjusted their seat and head restraint properly (Y page 97).

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 96). You also have tomake sure that an air bag can inflate properly if deployed (Y page 46). 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 "Triggering of the Emer- gency Tensioning Devices and air bags" (Y page 54). For more information about children traveling with you in the vehicle and on child restraint

systems, see "Children in the vehicle" (Y page 57).

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. This poses an increased risk of injury or even fatal injury. Never modify parts of the restraint system. Never tamper with the wiring, the electronic components or their software. If it is necessary tomodify an air bag system to accommodate a person with disabilities, con- tact an authorized Mercedes-Benz Center for details. USA only: for further information con- tact our Customer Assistance Center at 1-800-FOR-MERCedes (18003676372).

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

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.

PASSENGER AIR BAG indicator lamp

PASSENGER AIR BAG OFF indicator lamp: and PASSENGER AIR BAG ON indicator lamp; are part of the Occupant Classifica- tion System (OCS). The indicator lamps display the status of the front-passenger front air bag. 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. RPASSENGER AIR BAG OFF lights up: the front-passenger front air bag is deactiva- ted. It will then not be deployed in the event of an accident.

Occupant safety 41

Sa fe ty

Z

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 49) and on "Children in the vehicle" (Y page 57). 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 49). Be sure to observe the notes on "Seat belts (Y page 42) and "Air bags" (Y page 46). 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 and seat belt force limiters

If the seat belt is pulled by the belt loop 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, a seat belt force limiter helps to reduce the force exerted by the seat belt on the vehicle occupant. The seat belt force limiters are synchronized with the front air bags which absorb part of the deceleration force. This can reduce the force exerted on the vehicle occupants during an accident.

! If the front-passenger seat is not occu- pied, do not engage the seat belt tongue in the buckle on the front-passenger seat. Otherwise, in the event of an accident, the Emergency Tensioning Device and front- passenger front air bag may be triggered and would 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.

42 Occupant safety Sa fe ty

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 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 twelve years old 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 in the "Children in the vehicle" sec- tion of this Operator's Manual (Y page 57) 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 49)

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 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.

Proper use of the seat belts Observe the safety notes on the seat belt (Y page 42). 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.

Occupant safety 43

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. 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. Also ensure that there are never objects between a person and the seat, e.g. cush- ions.

Seat belts are only intended to secure and restrain vehicle occupants. Always observe the notes in the "Stowage options/compart-

ments" section for securing objects, luggage or loads (Y page 254).

Fastening seat belts Observe the safety notes on the seat belt (Y page 42) and the notes on correct use of seat belts (Y page 43).

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.

Basic illustration X Press release button:, hold belt tongue; firmly and guide back towards belt loop=.

Seat belt adjustment AMG vehicles: the "seat-belt adjustment" function is not available. 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 in the on-board computer (Y page 207).

Belt warning for the driver and front passenger The7 seat belt warning lamp in the instru- ment cluster is a reminder that all vehicle occupants must wear 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.

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 54). 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- 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 twelve years of age and less than 5 ft (1.50 m) tall in suitable child restraint systems. 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 41). RAlways observe the instructions and safety notes on the "Occupant Classification Sys- tem (OCS)" (Y page 49) and on "Children in the vehicle" (Y page 57) 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.

46 Occupant safety Sa fe ty

Rno accessories, such as cup holders, are attached to the vehicle within the deploy- ment area of an air bag, e.g. to doors or side windows. 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 anymore. 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.

Front air bags

Driver's air bag: deploys in front of the steering wheel. Front-passenger front air

bag; deploys in front of and above the glove box. When deployed, the front air bags offer addi- tional head and thorax protection for the occupants in the driver's and front-passenger seats. The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps inform you of the status of the front- passenger front air bag (Y page 41). The 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 49). The PASSENGER AIR BAG ON indicator lamp is lit (Y page 49) Rthe restraint system control unit predicts a high accident severity

Knee bags

Driver's knee bag: deploys under the steer- ing column and front-passenger knee bag; under the glove box. The driver's and front- passenger knee bags are triggered together with the front air bags. The driver's and front-passenger knee bags offer additional thigh, knee and lower leg pro- tection.

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.

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. 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 deploys under the following conditions: 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.

Head bags

Head bags: deploy in the area of the side windows at the front. When deployed, the headbag enhances the level of protection for the head. However, it does not protect the: Rchest Rarms In the event of a side impact, the headbag 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 headbagmay be deployed in other accident situations (Y page 54). The headbag on the front-passenger side does not deploy under the following condi- tions: ROCS has detected that the front-passenger seat is unoccupied. Rthe front-passenger seat belt is not fas- tened.

If the belt tongue is engaged in the belt buckle, the headbag on the front-passenger side deploys if an appropriate accident situa- tion occurs. In this case, deployment is inde- pendent of whether the front-passenger seat is occupied or not.

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 and front-passenger knee bag are either enabled or deactivated. The system does not deactivate: Rthe side impact air bag Rthe front-passenger head 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 you install a child restraint system on the front-passenger seat, be sure to observe the correct positioning of the child restraint sys- tem. Never place objects under or behind the child restraint system, e.g. cushions. The entire base of the child restraint systemmust always rest on the seat cushion of the front- passenger seat. The backrest of the forward- facing child restraint systemmust lie as flat as possible against the backrest of the front- passenger seat. The child restraint systemmust not touch the roof or be subjected to a load 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.

X Press the Start/Stop button once or twice, or turn the SmartKey to position 1 or 2 in the ignition lock. The system carries out self-diagnostics.

The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps must light up simultaneously for approx- imately six seconds. The indicator lamps display the status of the front-passenger front air bag. 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. RPASSENGER AIR BAG OFF lights up: the front-passenger front air bag is deactiva- ted. It will then not be deployed in the event of an accident.

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 223). 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 53).

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. Move the front-passenger seat as far back as possible. Always make sure that the shoulder belt strap is correctly routed from the vehicle belt loop to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed forwards and downwards from the belt loop. 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 twelve months old, in a stand- ard child restraint system, 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. But even in the case of a twelve-month-old child, in a standard child restraint system, the PASSENGER AIR BAG ON can light up permanently 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. Make sure that the condi- tions for a correct classification are met. If the PASSENGER AIR BAG ON indicator lamp is still lit, do not install a child restraint system on the front-passenger 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.

- 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 57). 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.

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- facing child restraint system must, as far as possible, be resting on the backrest of the front-passenger seat. Always comply with the child restraint system manufacturer's instal- lation instructions.

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.

For your own safety and that of your front passenger, it is important that you have deployed air bags replaced and faulty 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 41) Rthe belt tongue has engaged in the belt buckle of the respective seat

If the restraint system control unit detects a more severe accident, further components of the restraint system are activated independ-

54 Occupant safety Sa fe ty

ently of each other in certain frontal collision situations: RFront air bags as well as driver's and front- passenger knee bags

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 41). 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 if the vehicle rolls over, the applicable components of the restraint sys- tem are activated independently of each other depending on the apparent type of acci- dent. RSide impact air bag on the side of impact, independently of the Emergency Tension- ing Device and the use of the seat belt on the driver's seat The side impact air bag on the front- passenger side deploys under the following conditions: - 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

RHead bag on the side of impact, independ- ently of the use of the seat belt and inde- pendently of whether the front-passenger seat is occupied REmergency Tensioning Devices, if the sys- tem determines that deployment can offer additional protection in this situation RHead bags on the driver's and front- passenger side in certain situations when the vehicle rolls over, if the system deter- mines that deployment can offer additional 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

NECK-PRO head restraints

Important safety notes

G WARNING The function of the head restraint may be impaired if you: Rattach objects such as coat hangers to the head restraints, for example Ruse head restraint covers If you do so, the head restraints cannot fulfill their intended protective function in the event of an accident. In addition, objects attached to the head restraints could endanger other vehicle occupants. There is an increased risk of injury. Do not attach any objects to the head restraints and do not use head restraint cov- ers.

Method of operation NECK-PRO head restraints reduce the likeli- hood of head and chest injuries. The NECK- PRO head restraints on the driver's and front- passenger seats are moved forwards and upwards in the event of a rear-end collision of a certain severity. This provides better head support. If the NECK-PRO head restraints have been triggered in an accident, you must reset the NECK-PRO head restraints on the drivers and front-passenger seat (Y page 56). Other- wise, the additional protection will not be available in the event of another rear-end col- lision. You can recognize when NECK-PRO head restraints have been triggered by the fact that they have moved forwards and can no longer be adjusted. Mercedes-Benz recommends that you have the NECK-PRO head restraints checked for functionality at a qualified specialist work- shop after a rear-end collision.

Resetting triggered NECK-PRO head restraints

Do not insert your finger between the uphols- tery of the head restraint and the seat. Pay particular attention while resetting the NECK- PRO head restraints. X Tilt the top of the NECK-PRO head restraint cushion forwards in the direction of arrow:.

X Push the NECK-PRO head restraint cushion down as far as it will go in the direction of arrow;.

X Firmly push the NECK-PRO head restraint cushion back in the direction of arrow= until the cushion engages.

X Repeat this procedure for the second NECK-PRO head restraint.

i Resetting the NECK-PRO head restraints requires a lot of strength. If you have diffi- culty resetting the NECK-PRO head restraints, have this work carried out at a qualified specialist workshop.

PRE-SAFE (anticipatory occupant protection system)

Introduction

PRE-SAFE is only available in vehicles with the Driving Assistance package. AMG vehicles: PRE-SAFE is not available. In certain hazardous situations, PRE-SAFE takes pre-emptive measures to protect the vehicle occupants.

56 Occupant safety Sa fe ty

Important safety notes

! Make sure that there are no objects in the footwell or behind the seats. There is a dan- ger that the seats and/or objects could be damaged when PRE-SAFE is activated.

Although your vehicle is equipped with PRE- SAFE, the possibility of injury in the event of an accident cannot be ruled out. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.

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 Ron vehicles with the Driving Assistance package: if BAS PLUS intervenes power- fully or the radar sensor system detects an imminent danger of collision in certain sit- uations

PRE-SAFE takes the following measures depending on the hazardous situation detec- ted: Rthe seat belts are pre-tensioned. Rif the vehicle skids, the side windows are closed so that only a small gap remains. Rvehicles with the memory function: the front-passenger seat is adjusted if it is in an unfavorable position. Rvehicles with the memory function: the front-passenger seat is adjusted if it is in an unfavorable position.

If the hazardous situation passes without resulting in an accident, PRE-SAFE slackens the belt pre-tensioning. 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. You will find information on the convenience func- tion under "Belt adjustment" (Y page 45).

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 Rvehicles with a memory function: the elec- trically adjustable steering wheel is raised Rthe engine is switched off and the fuel sup- ply is cut off Rvehicles with mbrace: automatic emer- gency call

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 42) and the notes on correct use of seat belts (Y page 43). A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lbs (18 kg) until they reach a height where a three-point seat belt can be properly fas- tened 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.

The seat belt on the front passenger's side is equipped with a special seat belt retractor. When activated, the special seat belt retrac- tor ensures that the seat belt cannot slacken once the child seat is secured. Installing a child restraint system: X Make sure you observe the child restraint systemmanufacturer's installation instruc- tions.

X Pull the seat belt smoothly out of the belt loop.

X Engage seat belt tongue in belt buckle.

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.

Further information on stowing objects, lug- gage and loads securely can be found under Stowing options/stowage compartments (Y page 254).

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 system of child restraint sys- tems is the seat belt system.

i If you install a child restraint system on the front-passenger seat, be sure to read and follow the information on the "Occu- pant Classification System (OCS)" (Y page 49). There you will also find infor- mation 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.

Child restraint system on the front- passenger seat

General notes If you install a child restraint system onto the front-passenger seat, always observe the instructions and safety notes on the "Occu- pant Classification System (OCS)" (Y page 49). 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 41) 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 you secure a child in a forward-facing child restraint system on the front-passenger seat, always move the front-passenger seat as far back as possible. The entire base of the child restraint systemmust always rest on the seat cushion of the front-passenger seat. The backrest of the child restraint systemmust lie as flat as possible against the backrest of the front-passenger seat. The child restraint sys- tem 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. Always make sure that the shoulder belt strap is correctly routed from the front-passenger seat belt loop to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed forwards and downwards from the front-passenger seat belt loop. 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 61) RBAS (Brake Assist System) (Y page 62) RCOLLISION PREVENTION ASSIST PLUS (distance warning function and Adaptive Brake Assist) (Y page 62) RESP (Electronic Stability Program) (Y page 65) REBD (Electronic Brake force Distribution) (Y page 69) RADAPTIVE BRAKE (Y page 69)

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

Important safety notes

i Observe the "Important safety notes" sec- tion (Y page 61).

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 243) and display messages which may be shown in the instrument cluster (Y page 212).

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.

Driving safety systems 61

Sa fe ty

Z

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 61).

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.

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 138).

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.

Activating or deactivating COLLISION PREVENTION ASSIST PLUS is activated after every ignition cycle. You can activate or deactivate COLLISION PREVEN- TION ASSIST PLUS in the on-board computer (Y page 203). When deactivated, the dis- tance warning function and the autonomous braking function are also deactivated.

62 Driving safety systems Sa fe ty

If COLLISION PREVENTION ASSIST PLUS is deactivated, the symbol appears in the assistance graphics display.

Distance warning function

General information i Observe the "Important safety notes" sec- tion for driving safety systems (Y page 61).

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. 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. If the distance warning function detects that there is a risk of a collision, youwill be warned visually and acoustically. Starting at a speed of approximately 4 mph (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. Up to a speed of approximately 44 mph (70 km/h), the distance warning function can also react to stationary obstacles, such as stopped or parked vehicles.

Important safety notes 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.

Detection of hazardous situations can be par- ticularly impaired by: 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 important safety notes in the "Breaking-in notes" section (Y page 138).

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. 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.

Function 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.

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

Vehicles without DISTRONIC PLUS: the autonomous braking function is available in the following speed ranges: R4 - 65 mph (7 - 105 km/h) for moving objects R4 - 31 mph (7 - 50 km/h) for stationary objects

Vehicles with DISTRONIC PLUS: the auton- omous braking function is available in the fol- lowing speed ranges: R4 - 124 mph (7 - 200 km/h) for moving objects R4 - 31 mph (7 - 50 km/h) for stationary objects

Due to the nature of the system, complicated but non-critical driving conditions may also cause the Autonomous Braking function to intervene.

Adaptive Brake Assist

General information i Observe the "Important safety notes" sec- tion (Y page 61).

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. 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. 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.

64 Driving safety systems Sa fe ty

Up to a speed of approximately 44 mph (70 km/h), Adaptive Brake Assist reacts to stationary obstacles. 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.

Important safety notes 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. Detection of hazardous situations can be par- ticularly impaired by: 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 after the first few kilometers of driving or after the COLLISION PREVEN- TION ASSIST PLUS system has been serv- iced Observe the important safety notes in the "Breaking-in notes" section (Y page 138).

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.

ESP (Electronic Stability Program)

General notes

i Observe the "Important safety notes" sec- tion (Y page 61).

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

Driving safety systems 65

Sa fe ty

Z

pulling away on wet or slippery roads. ESP can also stabilize the vehicle during braking.

ETS (Electronic Traction System)

i Observe the "Important safety notes" sec- tion (Y page 61).

ETS traction control is part of ESP. ETS brakes the drive wheels individually 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 transferred to the wheel or wheels with traction. ETS remains active when you deactivate ESP.

i Mercedes-AMG vehicles: your vehicle may be equipped with 20-inch tires on the rear axle. After changing to 19 inch wheels, ETSmay intervene noticeably earlier during the first few kilometers. After approx- imately 10 km ETS will function as usual again. Information on the dimensions and types of wheels and tires for your vehicle can be found in the "Wheel/tire combina- tions" section (Y page 335).

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.

When towing the vehicle with the rear axle raised, observe the notes on ESP (Y page 303). ESP is only deactivated if the warning lamp is lit continuously. If the warning lamp and the warn- ing lamp are lit continuously, ESP not avail- able due to a malfunction.

Observe the information on warning lamps (Y page 245) and display messages which may be shown in the instrument cluster (Y page 212).

i 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 auto- matically 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.

driving. This allows you to identify pedes- trians, cyclists and animals. Active: when the lights are switched on.

Adaptive Highbeam Assist

General notes

You can use this function to set the head- lamps to change between low beam and high beam automatically. The system recognizes vehicles with their lights on, either approach- ing from the opposite direction or traveling in front of your vehicle, and consequently switches the headlamps from high beam to low beam. The system automatically adapts the low- beam headlamp range depending on the dis- tance to the other vehicle. Once the system no longer detects any other vehicles, it reac- tivates the high-beam headlamps. The system's optical sensor is located behind the windshield near the overhead control panel.

Important safety notes

G WARNING Adaptive HighbeamAssist does not recognize road users: Rwho have no lights, e.g. pedestrians Rwho have poor lighting, e.g. cyclists Rwhose lighting is blocked, e.g. by a barrier In very rare cases, Adaptive Highbeam Assist may fail to recognize other road users that have lights, or may recognize them too late. In this or similar situations, the automatic high- beam headlamps will not be deactivated or activated regardless. There is a risk of an acci- dent. Always carefully observe the traffic conditions and switch off the high-beam headlamps in good time.

Adaptive Highbeam Assist cannot take into account road, weather or traffic conditions. Adaptive Highbeam Assist is only an aid. You are responsible for adjusting the vehicle's lighting to the prevailing light, visibility and traffic conditions. In particular, the detection of obstacles can be restricted if there is: Rpoor visibility, e.g. due to fog, heavy rain or snow Rdirt on the sensors or the sensors are obscured

Switching Adaptive Highbeam Assist on/off X To switch on: turn the light switch to. X Press the combination switch beyond the pressure point in the direction of arrow:. The _ indicator lamp in the multifunc- tion display lights up when it is dark and the light sensor activates the low-beam head- lamps.

Replacing bulbs

Important safety notes

Xenon bulbs

G DANGER Xenon bulbs carry a high voltage. You can get an electric shock if you remove the cover of the Xenon bulb and touch the electrical con- tacts. There is a risk of fatal injury. Never touch the parts or the electrical con- tacts of the Xenon bulb. Always have work on the Xenon bulbs carried out at a qualified spe- cialist workshop.

If your vehicle is equipped with Xenon bulbs, you can recognize this by the following: the cone of light from the Xenon bulbs moves from the top to the bottom and back again when you start the engine. For this to be observed, the lights must be switched on before starting the engine. Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly.

Other bulbs

G WARNING Bulbs, lamps and connectors can get very hot when operating. If you change a bulb, you could burn yourself on these components. There is a risk of injury. Allow these components to cool down before changing a bulb.

Do not use a bulb that has been dropped or if its glass tube has been scratched. The bulb may explode if: Ryou touch it Rit is hot Ryou drop it Ryou scratch it Only operate bulbs in enclosed lamps designed for that purpose. Only install spare bulbs of the same type and the specified volt- age. Marks on the glass tube reduce the service life of the bulbs. Do not touch the glass tube with your bare hands. If necessary, clean the glass tubewhen coldwith alcohol or spirit and rub it off with a lint-free cloth. Protect bulbs from moisture during opera- tion. Do not allow bulbs to come into contact with liquids. There are bulbs other than the Xenon bulbs that you cannot replace. Replace only the bulbs listed (Y page 115). Have the bulbs that you cannot replace yourself changed at a qualified specialist workshop.

114 Replacing bulbs Li gh ts an d w in ds hi el d w ip er s

If you require assistance changing bulbs, con- sult a qualified specialist workshop. If the new bulb still does not light up, consult a qualified specialist workshop. Bulbs and lamps are an important aspect of vehicle safety. You must therefore make sure that these function correctly at all times. Have the headlamp setting checked regularly.

Windshield wipers

Switching the windshield wipers on/off ! Do not operate the windshield wipers when the windshield is dry, as this could damage the wiper blades. Moreover, dust that has collected on the windshield can scratch the glass if wiping takes placewhen the windshield is dry. If it is necessary to switch on thewindshield wipers in dry weather conditions, always use washer fluid when operating the wind- shield wipers.

! If the windshield wipers leave smears on the windshield after the vehicle has been washed in an automatic car wash, wax or other residues may be the reason for this. Clean the windshield using washer fluid after washing the vehicle in an automatic car wash.

! Intermittent wiping with rain sensor: due to optical influences and the windshield becoming dirty in dry weather conditions, the windshield wipers may be activated inadvertently. This could then damage the windshield wiper blades or scratch the windshield. For this reason, you should always switch off the windshield wipers in dry weather.

In the or position, the appropriate wiping frequency is set automatically accord- ing to the intensity of the rain. In the position, the rain sensor is more sensitive than in the position, causing the wind- shield wiper to wipe more frequently. If the wiper blades are worn, the windshield will no longer be wiped properly. This could prevent you from observing the traffic condi- tions.

Replacing the wiper blades

Important safety notes

G WARNING If the windshield wipers begin to move while you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of injury. Always switch off the windshield wipers and ignition before changing the wiper blades.

! To avoid damaging the wiper blades, make sure that you touch only the wiper arm of the wiper.

! Never open the hood if a windshield wiper arm has been folded away from the wind- shield. Never fold awindshieldwiper armwithout a wiper blade back onto the windshield. Hold the windshield wiper arm firmly when you change the wiper blade. If you release the windshield wiper arm without a wiper blade and it falls onto the windshield, the

windshield may be damaged by the force of the impact. Mercedes-Benz recommends that you have the wiper blades changed at a qualified specialist workshop.

! Always position the windshield wiper arms vertically before folding them away from the windshield. By doing so, you will avoid damage to the hood.

Useful information

i This Operator's Manual describes all models and all standard andoptional 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 25).

Overview of climate control systems

General notes Observe the settings recommended on the following pages. The windows could other- wise fog up. To prevent the windows from fogging up: Rswitch off climate control only briefly Rswitch on air-recirculation mode only briefly Rswitch on the cooling with air dehumidifi- cation function Rswitch on the defrost windshield function briefly, if required

Climate control regulates the temperature and the humidity in the vehicle interior and filters undesirable substances out of the air. Climate control can only be operated when the engine is running. Optimum operation is only achieved with the side windows and roof closed. The residual heat function can only be acti- vated or deactivated with the ignition switched off (Y page 133).

i When the weather is warm, ventilate the vehicle for a brief period. This will speed up the cooling process and the desired vehicle interior temperature will be reached more quickly.

i The integrated filter filters out most par- ticles of dust and soot and completely fil- ters out pollen. It also reduces gaseous pol- lutants and odors. A clogged filter reduces the amount of air supplied to the vehicle interior. For this reason, you should always observe the interval for replacing the filter, which is specified in the Maintenance Booklet. As it depends on environmental conditions, e.g. heavy air pollution, the interval may be shorter than stated in the Maintenance Booklet.

Useful information

i This Operator's Manual describes all models and all standard andoptional 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.

Notes on breaking-in a new vehicle

Important safety notes The sensor system of some driving and driv- ing safety systems adjusts automatically while a certain distance is being driven after the vehicle has been delivered or after repairs. Full system effectiveness is not reached until the end of this teach-in proce- dure. New and replaced brake pads and discs only reach their optimum braking effect after sev- eral hundred kilometers of driving. Compen- sate for this by applying greater force to the brake pedal.

The first 1000 miles (1500 km) The more you look after the engine when it is new, the more satisfied you will be with its performance in the future. RYou should therefore drive at varying vehi- cle and engine speeds for the first 1,000 miles (1,500 km). RAvoid heavy loads, e.g. driving at full throt- tle, during this period. RChange gear in good time, before the tach- ometer needle is of the way to the red area of the tachometer.

RDo not manually shift to a lower gear to brake the vehicle. RTry to avoid depressing the accelerator pedal beyond the point of resistance (kick- down). RIdeally, for the first 1,000miles (1,500 km), drive in program C.

After 1,000 miles (1,500 km), you can increase the engine speed gradually and bring the vehicle to full speed. Additional breaking-in notes for Mercedes- AMG vehicles: RDo not drive faster than 85 mph (140 km/h) for the first 1,000 miles (1,500 km). ROnly allow the engine to reach a maximum engine speed of 4,500 rpm briefly. RChange gear in good time. You should also observe these notes on breaking in if the engine or parts of the drive train on your vehicle have been replaced. Always observe the maximum permissible speed.

Self-locking rear axle differential (Mercedes-AMG vehicles) Your vehicle is equipped with a self-locking differential on the rear axle. Change the oil to improve protection of the rear axle differential: Rafter a breaking-in period of 1,850 miles (3,000 km) Revery 31,000 miles (50,000 km) or 3 years

These oil changes prolong the service life of the differential. Have the oil change carried out at a qualified specialist workshop.

Important safety notes

G WARNING Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal. The operating and road safety of the vehicle is jeopardized. There is a risk of an accident. Make sure that all objects in the vehicle are stowed correctly, and that they cannot enter the driver's footwell. Install the floormats securely and as specified in order to ensure sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on top of one another.

G WARNING Unsuitable footwear can hinder correct usage of the pedals, e.g.: Rshoes with thick soles Rshoes with high heels Rslippers There is a risk of an accident. Wear suitable footwear to ensure correct usage of the pedals.

G WARNING If you switch off the ignition while driving, safety-relevant functions are only available with limitations, or not at all. This could affect, for example, the power steering and the brake boosting effect. You will require considerably more effort to steer and brake. There is a risk of an accident. Do not switch off the ignition while driving.

G WARNING If the parking brake has not been fully released when driving, the parking brake can: Roverheat and cause a fire Rlose its hold function. There is a risk of fire and an accident. Release the parking brake fully before driving off.

! Do not warm up the engine with the vehi- cle stationary. Drive off immediately. Avoid high engine speeds and driving at full throt- tle until the engine has reached its operat- ing temperature. Only shift the automatic transmission to the desired drive position when the vehicle is stationary. Where possible, avoid spinning the drive wheels when pulling away on slippery roads. You could otherwise damage the drive train.

! Mercedes-AMG vehicles: at low engine oil temperatures below 68 (+20 ), the maximum engine speed is restricted in order to protect the engine. To protect the engine and maintain smooth engine oper- ation, avoid driving at full throttle when the engine is cold.

KEYLESS-GO

General notes Vehicles with KEYLESS-GO are equipped with a SmartKey featuring an integrated KEYLESS- GO start function and a detachable Start/ Stop button. The Start/Stop buttonmust be inserted in the ignition lock and the SmartKey must be in the vehicle. When you insert the Start/Stop button into the ignition lock, the system needs approx- imately two seconds recognition time. You can then use the Start/Stop button. Pressing the Start/Stop button several times in succession corresponds to the different key positions in the ignition lock. This is only the case if you are not depressing the brake pedal. If you depress the brake pedal and press the Start/Stop button, the engine starts immedi- ately. A checkwhich periodically establishes a radio connection between the vehicle and the SmartKey determines whether a valid Smart- Key is in the vehicle. This occurs, for example, when starting the engine. To start the vehicle without actively using the SmartKey: Rthe Start/Stop button must be inserted in the ignition lock. Rthe SmartKey must be in the vehicle. Rthe vehicle must not be locked with the SmartKey or KEYLESS-GO (Y page 73).

Do not keep the SmartKey: Rwith electronic devices, e.g. a mobile phone or another SmartKey. Rwith metallic objects, e.g. coins or metal foil. Rinside metallic objects, e.g. a metal case. This can impair the functionality of the KEY- LESS-GO key.

If you lock the vehicle with the SmartKey's remote control or with KEYLESS-GO, after a short time: Ryou will not be able to switch on the ignition with the Start/Stop button. Ryou will not be able to start the engine with the Start/Stop button until the vehicle is unlocked again.

i The engine can be switched off while the vehicle is in motion by pressing and holding the Start/Stop button for three seconds. This function operates independently of the ECO start/stop automatic engine switch- off function.

Key positions with KEYLESS-GO

: Start/Stop button ; Ignition lock As soon as the ignition is switched on, all the indicator lamps in the instrument cluster light up. Further information on situations where an indicator lamp either fails to go out after starting the engine or lights up while driving (Y page 243). If Start/Stop button: has not yet been pressed, this corresponds to the key being removed from the ignition. X To switch on the power supply: press Start/Stop button: once. The power supply is switched on. You can now activate the windshield wipers, for example. If you then open the driver's door when in this position, the power supply is deactiva- ted.

i Mercedes-AMG vehicles: the exhaust flap of the exhaust system is checked after each cold start. A resulting noise can be heard during this process.

i During a cold start, the engine runs at higher speeds to enable the catalytic con- verter to reach its operating temperature. The sound of the enginemay change during this time.

Automatic transmission X Shift the transmission to position P. The transmission position display in the multifunction display shows P.

i You can start the engine in transmission position P and N.

Starting procedure with the SmartKey To start the engine using the SmartKey instead of KEYLESS-GO, pull the Start/Stop button out of the ignition lock. X Turn the SmartKey to position 3 in the igni- tion lock and release it as soon as the engine is running (Y page 139).

Using KEYLESS-GO to start the engine The Start/Stop button can be used to start the vehicle manually without inserting the SmartKey into the ignition lock. The Start/ Stop button must be inserted in the ignition lock and the SmartKeymust be in the vehicle. This mode for starting the engine operates independently of the ECO start/stop auto- matic engine start function. X Depress the brake pedal and keep it depressed.

X Press the Start/Stop button once (Y page 140). The engine starts.

Pulling away

General notes

G WARNING If the engine speed is above the idling speed and you engage transmission position D or R, the vehicle could pull away suddenly. There is a risk of an accident. When engaging transmission position D or R, always firmly depress the brake pedal and do not simultaneously accelerate.

! Change gear in good time and avoid spin- ning the wheels. You could otherwise dam- age the vehicle.

Depress the accelerator carefully when pull- ing away. The vehicle locks centrally once you have pulled away. The locking knobs in the doors drop down. You can open the doors from the inside at any time. You can also deactivate the automatic locking feature (Y page 206). It is only possible to shift the transmission from position P to the desired position if you depress the brake pedal. Only then is the shift lock released.

i Upshifts take place at higher engine speeds after a cold start. This helps the catalytic converter to reach its operating temperature more quickly.

Information on the automatic release of the electric parking brake (Y page 161).

Hill start assist Hill start assist helps you when pulling away forwards or in reverse on an uphill gradient. It holds the vehicle for a short time after you have removed your foot from the brake pedal. This gives you enough time to move your foot from the brake pedal to the accelerator pedal and to depress it before the vehicle begins to roll.

142 Driving Dr iv in g an d pa rk in g

G WARNING After a short time, hill start assist will no lon- ger brake your vehicle and it could roll away. There is a risk of an accident and injury. Therefore, quickly move your foot from the brake pedal to the accelerator pedal. Never leave the vehicle when it is held by hill start assist.

Hill start assist is not active if: Ryou are pulling away on a level road or on a downhill gradient. Rthe transmission is in position N. Rthe electric parking brake is applied. RESP is malfunctioning.

ECO start/stop function

Introduction The ECO start/stop function switches the engine off automatically if the vehicle is stop- ped under certain conditions. The engine starts automatically when the driver wants to pull away again. The ECO start/stop function thereby helps you to reduce the fuel consumption and emissions of your vehicle.

Important safety notes

G WARNING If the engine is switched off automatically and you exit the vehicle, the engine is restarted automatically. The vehicle may begin moving. There is a risk of accident and injury. If you wish to exit the vehicle, always turn off the ignition and secure the vehicle against rolling away.

9G-TRONIC: in the event of a mal- function of the vehicle's electron- ics, the transmission may lock in position P. Have the vehicle elec- tronics checked immediately at a qualified specialist workshop.

C Reverse gear Only shift the transmission into position R when the vehicle is sta- tionary.

A Neutral Do not shift the transmission to N while driving. Otherwise, the auto- matic transmission could be dam- aged. No power is transmitted from the engine to the drive wheels. Releasing the brake pedal will allow you to move the vehicle freely, e.g. to push it or tow it. If ESP is deactivated or faulty: shift the transmission only to posi- tion N if the vehicle is in danger of skidding, e.g. on icy roads.

! Rolling in neutralN can damage the drive train.

7 Drive The automatic transmission changes gear automatically. All forward gears are available.

Driving tips

Changing gear The automatic transmission shifts to the indi- vidual gears automatically when it is in trans- mission position D. This automatic gear shift- ing behavior is determined by: Rthe selected drive program (Y page 152) Rthe position of the accelerator pedal (Y page 151) Rthe road speed

Accelerator pedal position Your style of driving influences how the auto- matic transmission shifts gear: Rlittle throttle: early upshifts Rmore throttle: late upshifts

Double-clutch function When shifting down, the double-clutch func- tion is active regardless of the currently selec- ted drive program. The double-clutch function reduces load change reactions and is condu- cive to a sporty driving style. The sound gen- erated by the double-clutch function depends on the drive program selected.

Kickdown Use kickdown for maximum acceleration. X Depress the accelerator pedal beyond the pressure point. The automatic transmission shifts to a lower gear depending on the engine speed.

X Ease off the accelerator pedal once the desired speed is reached. The automatic transmission shifts back up.

Example: program selector button

The program selector button allows you to choose between different driving character- istics. X Press program selector button: repeat- edly until the letter for the desired drive program appears in the multifunction dis- play.

On Mercedes-AMG vehicles, drive program E is called drive program C.

E Economy C Controlled Efficiency

Comfortable, economical driving

S Sport Sporty driving style

M Manual Manual gear shifting

i The automatic transmission switches to automatic drive program E (drive program C in Mercedes-AMG vehicles).

i Mercedes-AMG vehicles: when in drive program C and under low load, the engine operates on just four cylinders. This is the case in city traffic or on a country road, for example. This reduces fuel consumption. Cylinder shut-off is inactive in drive pro- grams S and M, so that the engine will operate with all eight cylinders.

i Further information about permanent drive program M (Y page 155). As well as this permanent drive programM, you can also activate temporary drive pro- gram M (Y page 153).

i For further information on the automatic drive program, see (Y page 153).

i The full range of functions for the steering wheel paddle shifters is available only once operating temperature has been reached.

i You can only change gear with the steer- ing wheel paddle shifters when the trans- mission is in position D.

Automatic drive program

Automatic drive programs E and S Drive program E (drive program C on Mercedes-AMG vehicles) is characterized by the following: Rcomfort-oriented engine and transmission settings. Roptimal fuel consumption resulting from the automatic transmission shifting up sooner. Rthe vehicle pulling away more gently in forward and reverse gears, unless the accelerator pedal is depressed fully. Rthe vehicle having improved driving stabil- ity, for example on slippery road surfaces. Rthe automatic transmission shifting up sooner. This results in the vehicle being driven at lower engine speeds and the wheels being less likely to spin.

Drive program S is characterized by the fol- lowing: Rsporty engine and transmission settings. Rthe vehicle pulling away in first gear. Rthe automatic transmission shifting up later. the fuel consumption possibly being higher as a result of the later automatic transmission shift points.

Manual drive program M

General notes In this drive program, you can briefly change gear yourself by using the steering wheel pad- dle shifters or the selector lever (7G-TRONIC). The transmission must be in position D. You can activate manual drive program M in the E and S automatic drive programs.

i As well as temporary drive program M, you can also activate permanent drive pro- gram M (Y page 152). Further information about permanent drive program M (Y page 155).

Activating X Shift the transmission to position D. X Pull the left or right steering wheel paddle shifter (Y page 152). Manual drive programM is temporarily acti- vated. The selected gear and M appear in the multifunction display.

Changing gear (7G-TRONIC) X To shift up: press the selector lever to the right towards D+.

or X Pull the right-hand steering wheel paddle shifter (Y page 152). In cases where it is permissible, the auto- matic transmission shifts up to the next gear. i If the maximum engine speed on the cur- rently engaged gear is reached and you continue to accelerate, the automatic transmission automatically shifts up in order to prevent engine damage.

X To shift down: press the selector lever to the left towards D.

or X Pull the left-hand steering wheel paddle shifter (Y page 152). In cases where it is permissible, the auto- matic transmission shifts down to the next gear.
