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.

22 Introduction

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. All authorized Mercedes-Benz Centers main- tain a supply of genuineMercedes-Benz parts for necessary service and repair work. In addi- tion, strategically located parts delivery cen- ters provide quick and reliable parts service. Always specify the vehicle identification num- ber (VIN) when ordering genuine Mercedes- Benz parts (Y page 399).

QR codes for the rescue card

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

Data stored in the vehicle

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

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

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

28 Introduction

("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 RChild restraint system RChild seat securing systems The components of the restraint systemwork in conjunction with each other. They can only deploy their protective function if, at all times, all vehicle occupants: Rhave fastened their seat belts correctly (Y page 47) Rhave adjusted their seat and head restraint properly (Y page 107).

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 106). You also have tomake sure that an air bag can inflate properly if deployed (Y page 50). 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 59). For more information about children traveling with you in the vehicle and on child restraint systems, see "Children in the vehicle" (Y page 62).

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.

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 53) and on "Children in the vehicle" (Y page 62). 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 53). Be sure to observe the notes on "Seat belts (Y page 46) and "Air bags" (Y page 50). 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 seat belt extender 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 for the front seats are synchronized with the front air bags, which absorb part of the deceleration force. This can reduce the force exerted on the vehi- cle occupants during an accident.

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

Important safety notes The use of seat belts and child restraint sys- tems is required by law in: Rall 50 states Rthe U.S. territories Rthe District of Columbia Rall Canadian provinces Even where this is not required by law, all vehicle occupants should correctly fasten their seat belts before starting the journey.

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

G WARNING The seat belt does not offer the intended level of protection if you have not moved the back- rest to an almost vertical position.When brak- ing or in the event of an accident, you could slide underneath the seat belt and sustain

46 Occupant safety Sa fe ty

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 62) 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 53)

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 46). All vehicle occupants must be wearing the seat belt correctly before beginning the jour- ney. Also make sure that all vehicle occu- pants are always wearing the seat belt cor- rectly while the vehicle is in motion. When fastening the seat belt, always make sure that: Rthe seat belt tongue is only inserted to the belt buckle belonging to that seat. Rthe seat belt is tight across your body. Avoid wearing bulky clothing, e.g. a winter coat. Rthe seat belt is not twisted.

Only then can the forces which occur be distributed over the area of the belt. Rthe shoulder section of the belt is always routed across the center of your shoulder. The shoulder section of the belt must not come into contact with your neck or be routed under your arm. 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 "Loading guidelines" for securing objects, luggage or loads (Y page 300).

Fastening seat belts Observe the safety notes on the seat belt (Y page 46) and the notes on correct use of seat belts (Y page 47).

G WARNING If the seat-belt extender is extended during the journey, the seat belt is not fitted properly on the body. The seat belt can then no longer perform its intended protective function. This poses an increased risk of injury or even fatal injury. Always make sure that the seat-belt extender is retracted during a journey.

Seat-belt extender

The seat-belt extender for the driver and front passenger helps you fasten your seat belt. Seat-belt extender= is extended when the respective door is closed and the SmartKey is turned to position 1 or 2 in the ignition lock.

You can also extend seat-belt extender= with seat-belt extender button?.

automatically, see "Belt adjustment" (Y page 50).

X If necessary, pull upwards on the shoulder section of the seat belt to tighten the belt across your body.

All seat belts except the driver's seat belt are equipped with a special seat belt retractor to securely fasten child restraint systems in the vehicle. Further information can be found under "Special seat belt retractor" (Y page 63).

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.

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

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 59). 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.

50 Occupant safety Sa fe ty

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. RChild restraint systems should be installed on the rear seats.

ROnly secure a child in a rearward-facing child restraint system on the front- passenger seat when the front-passenger front air bag is deactivated. If the PASSENGER AIR BAGOFF indicator lamp is permanently lit, the front-passenger front air bag is deactivated (Y page 45). RAlways observe the instructions and safety notes on the "Occupant Classification Sys- tem (OCS)" (Y page 53) and on "Children in the vehicle" (Y page 62) 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. Do not place any objects on the dashboard e.g. above the front-passenger front air bag. Rthere are no objects between the seat, door and B-pillar. Rno hard objects, e.g. coat hangers, hang on the grab handles or coat hooks. Rno accessories, such as cup holders, are attached to the vehicle within the deploy- ment area of an air bag, e.g. to doors, side windows, rear side trim or side walls. Rno heavy, sharp-edged or fragile objects are in the pockets of your clothing. Store such objects in a suitable place.

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

G WARNING Sensors to control the air bags are located in the doors. Modifications or work not per- formed correctly to the doors or door panel- ing, as well as damaged doors, can lead to the function of the sensors being impaired. The air bags might therefore not function properly 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 front seats. The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps inform you about the status of the front- passenger front air bag (Y page 45). 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 53).

The PASSENGER AIR BAG ON indicator lamp is lit (Y page 54) 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 for the occupants in the front seats.

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.

52 Occupant safety Sa fe ty

Front side impact air bags: and rear side impact air bags; deploy next to the outer bolster of the seat backrest. When deployed, the side impact air bag offers additional thorax protection. It also offers additional pelvis protection for occupants in the front seats. However, it does not protect the: Rhead Rneck Rarms In the event of a side impact, the side impact air bag is deployed on the side on which the impact occurs. The side impact air bag on the front- passenger side (front) deploys under the fol- lowing 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.

Window curtain air bags

Window curtain air bags: are integrated into the side of the roof frame and deployed in the area from the A-pillar to the C-pillar. When deployed, the window curtain air bag enhances the level of protection for the head. However, it does not protect the chest or arms. In the event of a side impact, the window cur- tain air bag is deployed on the side on which the impact occurs. If the system determines that they can offer additional protection to that provided by the seat belt, a window curtain air bag may be deployed in other accident situations (Y page 59).

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 window curtain air bag Rthe Emergency Tensioning Devices

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

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

If it is absolutely necessary to install a child restraint system on the front-passenger seat, be sure to observe the correct positioning of the child restraint system. Never place objects under or behind the child restraint system, e.g. cushions. Fully retract the seat cushion length. The entire base of the child restraint systemmust always rest on the seat cushion of the front-passenger seat. The backrest of the 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.

Occupant Classification System opera- tion (OCS)

: PASSENGER AIR BAG OFF indicator lamp ; PASSENGER AIR BAG ON indicator lamp The indicator lamps inform you whether the front-passenger front air bag is deactivated or enabled. 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 264). 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

54 Occupant safety Sa fe ty

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 58).

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

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

If OCS determines that: Rthe front-passenger seat is unoccupied, the PASSENGER AIR BAG OFF indicator lamp lights up after the system self-test and remains lit. This indicates that the front- passenger front air bag is deactivated. Rthe front-passenger seat is occupied by a child of up to 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. It is recommended that you install the child restraint system on a suit- able rear seat. Rthe front-passenger seat is occupied by a person of smaller stature (e.g. a teenager or small adult), either the PASSENGER AIR BAG ON or PASSENGER AIR BAG OFF indi- cator lamp lights up and remains lit after the system self-test depending on the result of the classification. - If the PASSENGER AIR BAG ON indicator lamp lights up, move the front-passenger seat as far back as possible. Alterna- tively, a person of smaller stature can sit on a rear seat.

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

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

If children are traveling in the vehicle, be sure to observe the notes on "Children in the vehi- cle" (Y page 62). When OCS is malfunctioning, the red 6 restraint system warning lamp in the instru- ment cluster and the PASSENGER AIR BAG OFF indicator lamp light up simultaneously. The front-passenger front air bag is deactiva- ted in this case and does not deploy during an accident. Have the system checked by quali- fied technicians as soon as possible. Consult an authorized Mercedes-Benz Center. The front-passenger seat should only be repaired at an authorized Mercedes-Benz Center. If the front-passenger seat, the seat cover or the seat cushion is damaged, have the nec- essary repair work carried out at an author- ized Mercedes-Benz Center.

For safety reasons, Mercedes-Benz recom- mends that you only use seat accessories that have been approved by Mercedes-Benz. If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy. The Occupant Classification System (OCS) categorizes the occupant in the front-passenger seat. Depending on that result, the front-passenger front air bag is either enabled or deactivated.

System self-test

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

G DANGER If the PASSENGER AIR BAG OFF indicator lamp remains lit after the system self-test, the front-passenger front air bag is disabled. It will not be deployed in the event of an accident. In this case, the front-passenger front air bag cannot perform its intended protective func- tion, e.g. when a person is seated in the front- passenger seat. That person could, for example, come into contact with the vehicle's interior, especially if the person is sitting too close to the dash- board. This poses an increased risk of injury or even fatal injury.

Deployment of Emergency Tensioning Devices and air bags

Important safety notes

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

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

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

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

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

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

Method of operation During the first stage of a collision, the restraint system control unit evaluates impor- tant physical data relating to vehicle deceler- ation or acceleration, such as: Rduration Rdirection Rintensity Based on the evaluation of this data, the restraint system control unit triggers the Emergency Tensioning Devices during a fron- tal or rear collision. An Emergency Tensioning Device can only be triggered, if: Rthe ignition is switched on Rthe components of the restraint system are operational; see "Restraint system warning lamp" (Y page 45) Rthe belt tongue is engaged in the buckle on the respective front-passenger seat

The Emergency Tensioning Devices in the rear compartment are triggered independ- ently of the lock status of the seat belts. If the restraint system control unit detects a more severe accident, further components of

Occupant safety 59

Z

the restraint system are activated independ- ently of each other in certain frontal collision situations: RFront air bags as well as driver's and front- passenger knee bags RWindow curtain air bag, if the system deter- mines that deployment can offer additional protection to that provided by the seat belt

The front-passenger front air bag is activated or deactivated depending on the person on the front-passenger seat. The front- passenger front air bag can only deploy in an accident if the PASSENGER AIR BAG ON indi- cator lamp is lit. Observe the information on the PASSENGER AIR BAG indicator lamps (Y page 45). 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 bags on the side of impact, independently of the Emergency Tension- ing Device and the use of the seat belt on the driver's seat and in the rear compart- ment seats The side impact air bag on the front- passenger side (front) 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

PRE-SAFE (anticipatory occupant protection system)

Introduction

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

Important safety notes

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

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

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

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

If the hazardous situation passes without resulting in an accident, PRE-SAFE slackens the belt pre-tensioning. On vehicles with mul- ticontour seats, the air pressure in the side bolsters is reduced again. All settings made by PRE-SAFE can then be reversed. If the seat belt pre-tensioning is not reduced: X Move the seat backrest or seat back slightly when the vehicle is stationary. The seat belt pre-tensioning is reduced and the locking mechanism is released.

The seat-belt adjustment is an integral part of the PRE-SAFE convenience function. Infor- mation about the convenience function can be found under "Belt adjustment" (Y page 50).

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

Introduction

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

Occupant safety 61

emptive measures to protect the vehicle occupants.

Important safety notes

The intervention of PRE-SAFE PLUS cannot prevent an imminent collision. The driver is not warned when PRE-SAFE PLUS intervenes. PRE-SAFE PLUS does not intervene if the vehicle is backing up. When driving, or when parking or exiting a parking space with assistance from Active Parking Assist, PRE-SAFE PLUS will not apply the brakes.

Function

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

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

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

Automatic measures after an acci- dent Immediately after an accident, the following measures are implemented, depending on the type and severity of the impact: Rthe hazard warning lamps are activated Rthe emergency lighting is activated Rthe vehicle doors are unlocked Rthe front side windows are lowered Rthe electrically adjustable steering wheel is raised Rthe engine is switched off and the fuel sup- ply is cut off Rvehicles with mbrace: automatic emer- gency call

Children in the vehicle

Important safety notes Accident statistics show that children secured in the rear seats are safer than chil- dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises that you install a child restraint system on a rear seat. Children are generally better pro- tected there. If a child younger than 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 Mercedes-Benz vehi- cles. The child restraint system must be appropriate to the age, weight and size of the child Rbe sure to observe the instructions and safety notes in this section in addition to the child restraint system manufacturer's installation instructions Rbe sure to observe the instructions and safety notes on the "Occupant Classifica- tion System (OCS)" (Y page 53)

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 46) and the notes on correct use of seat belts (Y page 47). 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.

All seat belts in the vehicle, except the driv- er's seat belt, are equippedwith a special seat belt retractor.

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

G WARNING If the child restraint system is installed incor- rectly or is not secured, it can come loose in

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

You will find further information on stowing objects, luggage or loads under "Loading guidelines" (Y page 300).

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

The securing systems of child restraint sys- tems are: Rthe seat belt system Rthe LATCH-type (ISOFIX) securing rings Rthe Top Tether anchorages (Coupe only) If it is absolutely necessary to carry a child on the front-passenger seat, be sure to observe the information on the "Occupant Classifica- tion System (OCS)" (Y page 53). There you will also find information on deactivating the front-passenger front air bag.

All child restraint systems must meet the fol- lowing standards: RU.S. Federal Motor Vehicle Safety Stand- ards 213 and 225 RCanadian Motor Vehicle Safety Standards 213 and 210.2

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

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

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

Always comply with the manufacturer's installation and operating instructions for the child restraint system used. Before every trip, make sure that the LATCH- type (ISOFIX) child restraint system is engaged correctly in both LATCH-type (ISO- FIX) securing rings

LATCH-type (ISOFIX) securing rings; on the rear seats are covered by folding upholstered lining= with Velcro fastening. X Fold upholstered lining= upwards. X Turn support: by 90. Upholstered lining= remains folded upwards.

X Install the LATCH-type (ISOFIX) child restraint system on both LATCH-type (ISO- FIX) securing rings;.

After you have removed the LATCH-type (ISO- FIX) child restraint system, you must turn support: on upholstered lining= by 90 again. Then fold upholstery lining= down. ISOFIX is a standardized securing system for specially designed child restraint systems on the rear seats. LATCH-type (ISOFIX) securing rings; for two LATCH-type (ISOFIX) child restraint systems are installed on the left and right rear seats. Non-LATCH-type (ISOFIX) child seats may also be used and can be installed using the vehicle's seat belt system. Install the child seat according to the manufacturer's instruc- tions.

Top Tether

Introduction Top Tether provides an additional connection between the child restraint system secured with a LATCH-type (ISOFIX) child seat mount and the vehicle. This helps reduce the risk of injury even further. If the child restraint sys-

X If necessary, move head restraint: back down again slightly (Y page 110). Make sure that you do not interfere with the cor- rect routing of Top Tether beltA.

Child restraint system on the front- passenger seat

General notes Accident statistics show that children secured in the rear seats are safer than chil- dren secured in the front-passenger seat. For this reason, Mercedes-Benz strongly advises that you install the child restraint system on a rear seat. If it is absolutely necessary to install a child restraint system on the front-passenger seat, be sure to read and follow the instructions and safety notes on the "Occupant Classifi- cation System (OCS)" (Y page 53). 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 45) is the front-passenger front air bag deactiva- ted.

66 Children in the vehicle Sa fe ty

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. Fully retract the seat cush- ion length. 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 extender to the shoulder belt guide on the child restraint system. The shoulder belt strap must be routed forwards from the retracted seat-belt extender for the front-passenger seat. Always observe the child restraint system manufacturer's installation and operating instructions.

Pets in the vehicle

G WARNING If you leave animals unattended or unsecured in the vehicle, they could press buttons or switches, for example. As a result, they could: Ractivate vehicle equipment and become trapped, for example Ractivate or deactivate systems, thereby endangering other road users

Unsecured animals could also be flung around the vehicle in the event of an accident or sud- den steering or braking, thereby injuring vehi-

cle occupants. There is a risk of an accident and injury. Never leave animals unattended in the vehi- cle. Always secure animals properly during the journey, e.g. use a suitable animal trans- port box.

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 68) RBAS (Brake Assist System) (Y page 68) RBASPLUS (BrakeAssistSystemPLUS)with Cross-Traffic Assist (Y page 69) RCOLLISION PREVENTION ASSIST PLUS (distance warning function and Adaptive Brake Assist) (Y page 70) RESP (Electronic Stability Program) (Y page 73) REBD (Electronic Brake force Distribution) (Y page 75) RADAPTIVE BRAKE (Y page 75) RPRE-SAFE Brake (Y page 75) RSTEER CONTROL (Y page 77)

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.

Driving safety systems 67

Z

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 362). 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 67).

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 288) and

display messages which may be shown in the instrument cluster (Y page 252).

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

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

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

BAS (Brake Assist System)

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

Important safety notes

i Observe the "Important safety notes" sec- tion (Y page 67).

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

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

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

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

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

i Pay attention to the important safety notes in the "Driving safety systems" sec- tion (Y page 67).

BAS PLUS is only available on vehicles with the Driving Assistance Plus package. For BAS PLUS to assist you when driving, the radar sensor system and the camera system must be operational. With the help of a sensor system and a cam- era system, BAS PLUS can detect obstacles: Rthat are in the path of your vehicle for an extended period of time Rthat cross the path of your vehicle In addition, pedestrians in the path of your vehicle can be detected. BAS PLUS detects pedestrians by using typi- cal characteristics such as the body contours and posture of a person standing upright. If the radar sensor system or the camera sys- tem is malfunctioning, BAS PLUS functions are restricted or no longer available. The brake system is still available with complete brake boosting effect and BAS.

i Observe the restrictions described in the "Important safety notes" sec- tion (Y page 69).

Important safety notes

G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. In such cases, BAS PLUS may: Rintervene unnecessarily Rnot intervene

There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake. Terminate the intervention in a non-critical driving situation.

G WARNING BAS PLUS cannot always clearly identify peo- ple, this is especially the case if they are mov- ing. BAS PLUS cannot intervene in these cases. There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake.

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

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

Driving safety systems 69

Sa fe ty

Z

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

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

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

- a pedestrian is concealed by other objects

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

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

Function To avoid a collision, BAS PLUS calculates the brake force necessary if: Ryou approach an obstacle, and RBAS PLUS has detected a risk of collision When driving at a speed under 20 mph (30 km/h): if you depress the brake pedal, BAS PLUS is activated. The increase in brake pressure will be carried out at the last possi- ble moment. When driving at a speed above 20 mph (30 km/h): if you depress the brake pedal sharply, BAS PLUS automatically raises the brake pressure to a value adapted to the traf- fic situation.

BAS PLUS provides braking assistance in haz- ardous situations with vehicles in front within a speed range between 4 mph (7 km/h) and 155 mph (250 km/h). At speeds of up to approximately 44 mph (70 km/h), BAS PLUS can react to: Rstationary objects in the path of your vehi- cle, e.g. stopped or parked vehicles Rpedestrians in the path of your vehicle Robjects crossing your path and that are recognized in the detection range of the sensors

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

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

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

COLLISION PREVENTION ASSIST PLUS

General information COLLISION PREVENTION ASSIST PLUS con- sists of a distance warning function with an autonomous braking function and adaptive Brake Assist. COLLISION PREVENTION ASSIST PLUS can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If COLLISION PREVENTION ASSIST PLUS detects that there is a risk of a collision, you will be warned visually and acoustically. If you

70 Driving safety systems Sa fe ty

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 150).

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

Distance warning function

General information The distancewarning function can help you to minimize the risk of a front-end collision with a vehicle ahead or reduce the effects of such a collision. If the distance warning function detects that there is a risk of a collision, you will be warned visually and acoustically.

Important safety notes i Observe the "Important safety notes" sec- tion for driving safety systems (Y page 67).

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

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

Function X To activate/deactivate: activate or deac- tivate the distance warning function in the on-board computer (Y page 245).

If the distance warning function is not activa- ted, the symbol appears in the assis- tance graphics display. 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.

Driving safety systems 71

Sa fe ty

Z

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 The autonomous braking function is available in the following speed ranges: Rfrom 4 mph (7 km/h) to approx. 65 mph (105 km/h) for moving objects Rfrom 4 mph (7 km/h) to approx. 31 mph (50 km/h) for stationary objects

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

Adaptive Brake Assist

i Observe the "Important safety notes" sec- tion (Y page 67).

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

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

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

Due to the nature of the system, particularly complicated but non-critical driving condi- tions may also cause Brake Assist to inter- vene. If adaptive Brake Assist is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS. With the help of adaptive Brake Assist, the distance warning signal can detect obstacles that are in the path of your vehicle for an extended period of time. If adaptive Brake Assist detects a risk of col- lision with the vehicle in front, it calculates the braking force necessary to avoid a colli- sion. If you apply the brakes forcefully, adap- tive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions.

72 Driving safety systems Sa fe ty

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

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

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

ESP (Electronic Stability Program)

General notes

i Observe the "Important safety notes" sec- tion (Y page 67).

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

ETS/4ETS (Electronic Traction System)

i Observe the "Important safety notes" sec- tion (Y page 67).

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

Important safety notes

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

Vehicles without 4MATIC: observe the notes on ESP (Y page 356) when towing the vehi- cle with a raised rear axle. ESP is only deactivated if the warning lamp is lit continuously. If the warning lamp lights up continu- ously, ESP is not available due to a malfunc- tion. Observe the information on warning lamps (Y page 290) and display messages which may be shown in the instrument cluster (Y page 252). Only use wheels with the recommended tire sizes. Only then will ESP function properly.

Characteristics of ESP

General information If the ESP warning lamp goes out before beginning the journey, ESP is automatically active. If ESP intervenes, the ESP warning lamp flashes in the instrument cluster.

If ESP intervenes: X Do not deactivate ESP under any circum- stances.

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

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

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

Deactivating/activating ESP

Important safety notes i Observe the "Important safety notes" sec- tion (Y page 67).

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

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

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

i Activate ESP as soon as the situations described above no longer apply. ESP will otherwise not be able to stabilize the vehi-

cle if the vehicle starts to skid or a wheel starts to spin.

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

Deactivating/activating ESP

You can deactivate or activate ESP via the on-board computer (Y page 74). ESP deactivated: The ESP OFF warning lamp in the instrument cluster lights up. ESP activated: The ESP OFF warning lamp in the instrument cluster goes out.

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

Crosswind Assist (vehicles without MAGIC BODY CONTROL)

General information Vehicles with MAGIC BODY CONTROL: infor- mation on stabilizing the vehicle in the event of crosswind (Y page 194). Strong crosswinds can cause your vehicle to deviate from a straight course. The crosswind driving assistance function integrated into ESP significantly reduces these effects.

74 Driving safety systems Sa fe ty

ESP intervenes automatically according to the direction and intensity of the crosswinds affecting your vehicle. ESP intervenes with stabilizing braking to assist you in keeping the vehicle in the lane. Crosswind Assist is active at vehicle speeds above 50 mph (80 km/h) when driving straight ahead or cornering gently.

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

EBD (electronic brake force distribu- tion)

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

Important safety notes

i Observe the "Important safety notes" sec- tion (Y page 67).

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

Observe information regarding indicator and warning lamps (Y page 288) as well as dis- play messages (Y page 255).

ADAPTIVE BRAKE ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addi- tion to the braking function, ADAPTIVEBRAKE

also has the HOLD function (Y page 192) and hill start assist (Y page 155).

PRE-SAFE Brake

General information

PRE-SAFE Brake can help you to minimize the risk of a collision with a vehicle ahead or a pedestrian, and reduce the effects of such a collision. If PRE-SAFE Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic brak- ing.

i Pay attention to the important safety notes in the "Driving safety systems" sec- tion (Y page 67).

PRESAFE Brake is only available in vehicles with the Driving Assistance Plus package. For PRE-SAFE Brake to assist you when driv- ing, the radar sensor system and the camera system must be switched on and be opera- tional. With the help of the radar sensor system and the camera system, PRE-SAFE Brake can detect obstacles that are in front of your vehi- cle for an extended period of time. In addition, pedestrians in the path of your vehicle can be detected. PRE-SAFE Brake detects pedestrians using typical characteristics such as the body con- tours and posture of a person standing upright.

i Observe the restrictions described in the "Important safety notes" sec- tion (Y page 75).

Important safety notes

G WARNING PRE-SAFE Brake will initially brake your vehi- cle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you brake yourself. Even after subsequent full application of the brakes

Driving safety systems 75

Sa fe ty

Z

a collision cannot always be avoided, partic- ularly when approaching at too high a speed. There is a risk of an accident. Always apply the brakes yourself and try to take evasive action, provided it is safe to do so.

In the event of a partial application of the brakes, the vehicle is brakedwith up to 50% of the full braking pressure.

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

G WARNING PRE-SAFE Brake cannot always clearly iden- tify people, especially if they are moving. In these cases, PRE-SAFE Brake cannot inter- vene. There is a risk of an accident. Always pay particular attention to the traffic situation and be ready to brake, especially if PRE-SAFE Brake warns you.

In order to maintain the appropriate distance to the vehicle in front and thus prevent a col- lision, you must apply the brakes yourself.

G WARNING PRE-SAFE Brake does not react: Rto small people, e.g. children Rto animals Rto oncoming vehicles Rto crossing traffic Rwhen cornering

As a result, PRE-SAFE Brake may neither give warnings nor intervene in all critical sit- uations. There is a risk of an accident. Always pay careful attention to the traffic sit- uation and be ready to brake.

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

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

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

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

- a pedestrian is concealed by other objects

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

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

76 Driving safety systems Sa fe ty

systemchecked at a qualified specialist work- shop.

Function X To activate/deactivate: activate or deac- tivate PRE-SAFE Brake in the on-board computer (Y page 245). If the PRE-SAFE Brake is not activated, the symbol appears in the multifunction display.

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

PRE-SAFE Brake can also brake the vehicle automatically under the following conditions: Rthe driver and front-passenger have their seat belts fastened and Rthe vehicle speed is between approx- imately 4 mph (7 km/h) and 124 mph (200 km/h)

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

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

If the risk of collision with the vehicle in front remains and you do not brake, take evasive action or accelerate significantly, the vehicle may perform automatic emergency braking, up to the point of full brake application. Auto- matic emergency braking is not performed

until immediately prior to an imminent acci- dent. You can prevent the intervention of the PRE- SAFE Brake at any time by: Rdepressing the accelerator pedal further. Ractivating kickdown. Rreleasing the brake pedal. The braking action of PRE-SAFE Brake is ended automatically if: Ryou maneuver to avoid the obstacle. Rthere is no longer a risk of collision. Rthere is no longer an obstacle detected in front of your vehicle.

STEER CONTROL

General information STEER CONTROL helps you by transmitting a noticeable steering force to the steering wheel in the direction required for vehicle stabilization. This steering assistance is provided in partic- ular if: Rboth right wheels or both left wheels are on a wet or slippery road surface when you brake. Rthe vehicle starts to skid.

Important safety notes

i Observe the "Important safety notes" sec- tion (Y page 67).

No steering support is provided from STEER CONTROL, if: RESP is malfunctioning. Rthe lighting is faulty. Power steering will, however, continue to function.

Cornering light function

The cornering light function improves the illu- mination of the road over a wide angle in the direction you are turning, enabling better vis- ibility in tight bends, for example. It can only be activated when the low-beam headlamps are switched on. Active: Rif you are driving at speeds below 25 mph (40 km/h) and switch on the turn signal or turn the steering wheel Rif you are driving at speeds between 25 mph (40 km/h) and 45 mph (70 km/h) and turn the steering wheel

The cornering lamp may remain lit for a short time, but is automatically switched off after no more than three minutes.

Adaptive Highbeam Assist Plus

General notes

With Adaptive Highbeam Assist Plus, you can automatically switch between low-beam, par- tial high-beam and high-beam headlamps. Partial high-beam is a form of illumination whereby the high-beam is directed past other road users. Other road users are kept out of the high-beam. This prevents glare. When there is a vehicle in front, for example, the high-beam headlamps illuminate the areas to its right and left, and the vehicle in front is illuminated by the low-beam headlamps. 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. If the high-beam or partial high-beam are causing too much reflection from traffic signs, the lights are automatically dimmed and glare for the driver caused by the reflec- tions is thus avoided. The system's optical sensor is located behind the windshield near the overhead control panel.

Important safety notes

G WARNING Adaptive Highbeam Assist Plus does not rec- ognize 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 Plus may not recognize road users who do have lights, or may recognize them too late. In this or similar situations, the automatic high- beam headlamps will not be deactivated or will be activated regardless. There is a risk of an accident. Always carefully observe the traffic conditions and switch off the high-beam headlamps in good time.

Adaptive Highbeam Assist Plus cannot take into account road, weather or traffic condi- tions. Adaptive Highbeam Assist Plus is only an aid. You are responsible for adjusting the vehicle's lighting to the prevailing light, visi- bility 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

Replacing bulbs

The front and rear light clusters of your vehi- cle are equipped with LED light bulbs. Do not replace the bulbs yourself. Contact a qualified specialist workshop which has the necessary specialist knowledge and tools to carry out the work required. 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.

! Vehicles with a rain sensor: if the wind- shield becomes dirty in dry weather condi- tions, the windshield wipers may be activa- ted 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 wipers to wipe more frequently. The washer fluid is fed through the wiper blades; when the screen is wiped with washer fluid , the water is emitted directly from the blades.

If you push and hold the combination switch beyond the point of resistance in the direction of arrowB, the manual wash program is activated. If you push and hold the combina- tion switch briefly beyond the point of resist- ance in the direction of arrowB, the auto- matic wash program is activated. 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. 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.

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 air humidity in the vehicle interior. The air filter cleans the air, thus improving the inte- rior climate. The "Cooling with air dehumidification" func- tion is only available when the engine is run- ning. Optimum climate control is only ach- ieved with the side windows and roof closed. If you start the engine using your smartphone, the last selected climate control setting is reactivated (Y page 154). The residual heat function can only be acti- vated or deactivated with the ignition switched off (Y page 143).

i Ventilate the vehicle for a brief period during warm weather, e.g. using the con-

venience opening feature (Y page 99). This will speed up the cooling process and the desired 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.

i It is possible that the blower may be acti- vated automatically 60 minutes after the SmartKey has been removed depending on various factors, e.g. the outside tempera- ture. The vehicle is then ventilated for 30 minutes to dry the climate control sys- tem.

The indicator lamp in the rocker switch lights up. RSet the temperature to 72 (22 ). ROnly use the "Windshield defrosting" func- tion briefly until the windshield is clear again.

ROnly use air-recirculation mode briefly, e.g. if there are unpleasant outside odors or when in a tunnel. The windows could oth- erwise fog up, since no fresh air is drawn into the vehicle in air-recirculation mode. RUse the residual heat function if youwant to heat or ventilate the vehicle interior when the ignition is switched off. The residual heat function can only be activated or deac- tivated with the ignition switched off. The residual heat function is switched off when the ignition is switched on.

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 1000 miles (1500 km). RAvoid heavy loads, e.g. driving at full throt- tle, during this period. RWhen shifting gears manually, upshift in good time, before the tachometer needle reaches 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). RAll vehicles (except Mercedes-AMG vehicles): ideally, for the first 1,000 miles (1,500 km), drive in drive program E.

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. RIdeally, for the first 1,000miles (1,500 km), drive in program C.

After 1000miles (1500 km), you can increase the engine speed gradually and accelerate the vehicle to full speed. 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.

Driving

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.

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

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.

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 83).

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 affect the functionality of the Smart- 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.

If you lock the vehicle centrally using the but- ton on the front door (Y page 89), you can continue to start the engine with the Start/ Stop button. The engine can be switched off while the vehi- cle 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 func- tion.

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.

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

When engaging transmission position D or R, always firmly depress the brake pedal and do not simultaneously accelerate.

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 90). 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 parking lock released. If you do not depress the brake pedal, the DIRECT SELECT lever can still be moved but the parking lock remains engaged.

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 172).

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.

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.
