If the 45 indicator lamp should not come on or is continuously lit, the system is not functioning. You must see an authorized Mercedes-Benz Center before seating any child on the front passenger seat. More information can be found in the “Practical hints” section (Y page 313). G Warning! Do not place powered-on laptops, mobile phones, electronic tags such as those used in ski passes and like electronic devices on the front passenger seat. Signals from such devices may interfere with the BabySmart™ air bag deactivation system. Such signal interference may cause the 45
indicator lamp not to come on during self-test. The SRS indicator lamp 6 and/or the 45 indicator lamp could be continuously lit, indicating that the system is not functioning. The front passenger front air bag could deploy inadvertently or fail to deploy in an accident. G Warning! The BabySmart™ air bag deactivation system will ONLY work with a special child seat designed to operate with it. It will not work with child seats which are not BabySmart™ compatible. Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness off the BabySmart™ air bag deactivation system. The bottom of the child seat must make full contact with the front passenger seat cushion. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of protecting the child. Follow the manufacturer’s instructions for installation of special child seats.2009-07-17T09:14:21+02:00 - Seite 48
Version: 2.11.8.1Seat belts Safety notes The use of seat belts and infant and child restraint systems is required by law in all 50
states, the District of Columbia, the U.S. territories and all Canadian provinces. Even where this is not the case, all vehicle occupants should have their seat belts fastened whenever the vehicle is in motion. i See “Children in the vehicle” (Y page 56) for information on Rinfants and children traveling with you inthe vehicle
Rrestraint systems for infants and children G Warning! Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts. Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. The air bags can only protect as intended if the occupants are properly wearing their seat belts. G Warning! Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries. The seat backrest and

Never let more people ride in the vehicle than there are seat belts available. Make sure everyone riding in the vehicle is correctly restrained with a separate seat belt. Never use a seat belt for more than one person at a time. G Warning! Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Also, the seat belt anchoring points must be checked. Only use seat belts which have been approved by Mercedes-Benz. Do not make any modifications to the seat belts. This can lead to unintended activation of the ETDs or to their failure to activate when necessary. Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. Have all work carried out only by qualified technicians. Contact an authorized Mercedes-Benz Center.
Proper use of seat belts G Warning! USE SEAT BELTS PROPERLY RSeat belts can only protect when used
properly. Never wear seat belts in any other way than as described in this section, as that could result in serious injuries in case of an accident.
REach occupant should wear their seat belt at all times, because seat belts help reduce the likelihood of and potential severity of injuries in accidents, including rollovers. The integrated restraint system includes

SRS (driver front air bag, driver side knee bag, front passenger front air bag, side impact air bags, pelvis air bags, window curtain air bags for door windows), Emergency Tensioning Devices (ETDs), seat belt force limiters, and front seat knee bolsters. The system is designed to enhance the protection offered to properly belted occupants in certain frontal (front air bags, driver’s side knee bag, and ETDs) and side (side impact air bags, pelvis air bags, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds and in certain rollovers (window curtain air bags and ETDs).
RNever wear the shoulder belt under your
arm, against your neck or off your shoulder. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries. The seat belt would also apply too much force to the ribs or abdomen, which could severely injure internal organs such as your liver or spleen. Adjust the seat belt so that the shoulder section is located as close as possible to the middle of the shoulder. It should not touch the neck. Never pass the shoulder portion of the seat belt under your arm. For this purpose, you can adjust the height of the seat belt outlet.
RPosition the lap belt as low as possible on your hips and not across the abdomen. If the lap belt is positioned across your abdomen, it could cause serious injuries in a crash.
RNever wear seat belts over rigid or
breakable objects in or on your clothing, such as eyeglasses, pens, keys etc., as these might cause injuries.
RMake sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing.

NECK-PRO active front head restraints The NECK-PRO active front head restraints are intended to offer the driver and front passenger increased protection from whiplash-type injuries. In the event of a rear- end collision, the NECK-PRO active front head restraints are designed to move forward and up in the direction of travel. They thus provide the head with increased support earlier on in the collision sequence. The NECK-PRO active front head restraints will move forward and up whether the seats are occupied or not. G Warning! Do not attach any objects (e.g. hangers) to the head restraint posts. Otherwise, the NECK- PRO active front head restraints may not be able to function properly or offer the intended degree of protection they were designed for in the event of a rear-end collision. G Warning! Only use seat or head restraint covers which have been tested and approved by Mercedes- Benz for your vehicle model.
Using other seat or head restraint covers may interfere with or prevent the activation of the NECK-PRO active front head restraints and/ or the deployment of the front side impact air bags or pelvis air bags. Contact an authorized Mercedes-Benz Center for availability. When the NECK-PRO active front head restraints have been triggered in an accident, the NECK-PRO active front head restraints must be reset. Otherwise, the NECK-PRO active front head restraints cannot offer any additional protection in the event of another rear-end collision. For information on resetting the activated NECK-PRO active front head restraints, see “Resetting activated head restraints” (Y page 316). You cannot remove the NECK-PRO active front head restraints. G Warning! For your protection, drive only with properly positioned head restraints. Adjust the head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation. For information on head restraint adjustment, see “Head restraint height” (Y page 89), or see “Head restraint fore and aft adjustment” (Y page 89).

The use of infant or child restraints is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces. Infants and small children should be seated in an appropriate infant or child restraint system. They must be properly secured in accordance with the manufacturer’s instructions for the child restraint. All infant or child restraint systems must comply with U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2. A statement by the child restraint manufacturer of compliance with these standards can be found on the instruction label on the restraint and in the instruction manual provided with the restraint. When using any infant restraint, toddler restraint, or booster seat, make sure to carefully read and follow all manufacturer’s instructions for installation and use. Please read and observe warning labels affixed to the inside of the vehicle and to infant or child restraints. G Warning! According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate

infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be properly secured with the vehicle’s seat belt, the seat belt and top tether strap, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions. Occupants, especially children, should always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Children can be killed or seriously injured by an inflating air bag. Note the following important information when circumstances require you to place a child in the front passenger seat: RUSA only: Your vehicle is equipped with air bag technology designed to deactivate the front passenger front air bag in your vehicle when the system senses the weight of a typical 12-month-old child or less along with the weight of a standard appropriate child restraint on the front passenger seat.
RUSA only: For children larger than the
typical 12-month-old child, the front passenger front air bag may or may not be activated. Always make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated.
RCanada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.

Version: 2.11.8.1RA child in a rear-facing child restraint on the
front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint in a backseat.
RIf you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 45 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 45 indicator lamp while driving to make sure the 45 indicator lamp is illuminated. If the 45 indicator lamp goes out or remains out, do not transport a child on the front passenger seat until the system has been repaired. A child in a rear-facing child restraint on the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates.
RIf you have to place a child in a forward-
facing child restraint on the front passenger seat, move the seat as far back as possible, use the proper child restraint recommended for the age, size and weight of the child, and secure child restraint with the vehicle’s seat belt according to the child seat manufacturer’s instructions. G Warning! Infants and small children should never share a seat belt with another occupant. During an accident, they could be crushed between the occupant and seat belt.
A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/ or the child is not properly secured in the child restraint. Children too big for a toddler restraint must ride in seats using regular seat belts. Position shoulder belt across chest and shoulder, not face or neck. A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lb (18 kg) until they reach a height where a lap/shoulder belt fits properly without a booster. When the child restraint is not in use, remove it from the vehicle or secure it with the seat belt to prevent the child restraint from becoming a projectile in the event of an accident.
Installation of infant and child restraint systems G Observe Safety notes, see page 56. G Warning! Always lock the seat backrests in their upright position when the rear seats are occupied by passengers. Lock the seat backrests in their upright position before installing top tether straps or when the extended cargo compartment is not in use. Make sure that seat backrests are secured properly by pushing and pulling on the seat backrests. If a seat backrest is not locked properly, the seat backrest could fold. The child seat would no longer be supported properly or positioned to provide its intended benefit. That could cause serious or even fatal injuries. This vehicle is equipped with tether anchorages for a top tether strap at each of the rear seating positions. Top tether straps enable an additional connection to be made between child restraint systems secured with LATCH-type (ISOFIX) anchors and rear seats. This can further reduce the risk of injury.

Driving safety systems Introduction This section contains information about the following driving safety systems: RABS (Antilock Brake System) RAdaptive Brake RBAS (Brake Assist System) RBAS PLUS (Brake Assist System PLUS) REBP (Electronic Brake Proportioning) RESC (Electronic Stability Control) RPRE-SAFE® Brake (Preventive Occupant
Safety System Brake)

Version: 2.11.8.162 Driving safety systems
i In winter operation, the maximum effectiveness of most of the driving systems described in this section is only achieved with winter tires, or snow chains as required.
Safety notes G Warning! The following factors increase the risk of accidents: RExcessive speed, especially in turns RWet and slippery road surfaces RFollowing another vehicle too closely The driving safety systems described in this section cannot reduce these risks or prevent the natural laws of physics from acting on the vehicle. They cannot increase braking or steering efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of a vehicle equipped with the driving safety systems described in this section must never be exploited in a reckless or dangerous manner which could jeopardize the user’s safety or the safety of others. Always adjust your driving style to the prevailing road and weather conditions and keep a safe distance to other road users and objects on the street. If a driving system malfunctions, other driving safety systems may also switch off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear.
ABS G Observe Safety notes, see page 62. G Warning! Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pumping the brake pedal defeats the purpose of the ABS and significantly reduces braking effectiveness. The Antilock Brake System (ABS) regulates the brake pressure so that the wheels do not lock during braking. This allows you to maintain the ability to steer your vehicle. The ABS is functional above a speed of approximately 5 mph (8 km/h) independent of road surface conditions. On slippery road surfaces, the ABS will respond even to light brake pressure. The ABS indicator lamp ! in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.
Braking At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal. The pulsation indicates that the ABS is in the regulating mode. X Keep firm and steady pressure on the brake
pedal while you feel the pulsation.
Continuous, steady brake pedal pressure yields the advantages provided by the ABS, namely braking power and the ability to steer the vehicle. The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.
Emergency brake maneuver X Keep continuous full pressure on the brake
pedal.

Version: 2.11.8.1G Warning! If the ABS malfunctions, other driving safety systems such as the BAS or the ESC are also switched off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear. If the ABS malfunctions, the wheels may lock during hard braking, reducing steering capability and extending the braking distance.
BAS G Observe Safety notes, see page 62. The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS provides full brake boost automatically, thereby potentially reducing the braking distance. X Apply continuous full braking pressure until
the emergency braking situation is over. The ABS will prevent the wheels from locking.
When you release the brake pedal, the brakes function again as normal. The BAS is then deactivated. G Warning! If the BAS malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase.
BAS PLUS The Brake Assist System PLUS (BAS PLUS) operates in emergency braking situations and uses radar sensors to assess the traffic situation. BAS PLUS assists you in braking at speeds above approximately 20 mph (30 km/h). When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 144). Canadian law does not permit the use of the radar
Driving safety systems
63
sensor system for vehicles from outside of Canada. When you switch off the radar system, the following functions are deactivated: RBAS PLUS RPRE-SAFE® Brake (Y page 69) RDISTRONIC PLUS (Y page 149) G Warning! BAS PLUS is a convenience system designed to assist the driver during vehicle operation. The responsibility for the vehicle speed and the distance to the vehicle ahead, including most importantly brake operation to assure safe stopping distance, always remains with the driver. Always pay attention to traffic conditions even while BAS PLUS is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late and could cause an accident. Personal or fatal injury to you or others may be the result.
i This device has been approved by the FCC as a “Vehicular Radar System”. The radar sensor is intended for use in an automotive radar system only. Removal, tampering, or altering of the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way. Any unauthorized modification to this device could void the user’s authority to operate the equipment.
BAS PLUS detects obstacles that are in your driving path for a sufficient period of time to permit the system to recognize these obstacles. If you approach the detected obstacle quickly, BAS PLUS calculates the level of brake power boost appropriate for the circumstance to supply when the driver applies the brakes. When you step quickly on the brake pedal in an emergency braking situation, BAS PLUS automatically regulates the brake power

Version: 2.11.8.164 Driving safety systems
boost to a level that is suitable for the traffic situation. If BAS PLUS requires a particularly high brake power boost, PRE-SAFE® is activated at the same time. X Keep constant pressure on the brake pedal
until the emergency braking situation is over. During this process, the ABS prevents the wheels from locking up.
The brakes will resume normal operation after Rthe brake pedal is released Rno obstacles are detected in your path Rthe system no longer senses a risk of a
collision
BAS PLUS is then deactivated. BAS PLUS can react to stationary obstacles such as standing or parked vehicles at road speeds of up to approximately 40 mph (70 km/h). BAS PLUS can only assist you when the radar sensors are switched on and functional. You can check whether the sensors are active by switching on DISTRONIC PLUS (Y page 149) or using the Radar sensors function in the instrument cluster control system. G Warning! BAS PLUS will only respond with brake assistance if it has clearly detected an object. Detection can be impeded by Rdirty or covered sensors Rsnowfall or heavy rain Rdisturbance from other radar sources Rstrong radar reflection such as in parking
garages
BAS PLUS uses radar signals that are not reflected well by narrow objects and absorptive materials. For this reason BAS PLUS will not react to persons, animals, and approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles driving in front of you, such as motorcycles and vehicles driving offset from your vehicle center. After a hard collision or damage to the front of the vehicle from an accident, have the adjustment and operation of the radar sensors checked by an authorized Mercedes- Benz Center. If BAS PLUS is not available due to a radar sensor malfunction, the braking system will continue to function normally with full brake boost and full standard BAS function.
Adaptive Brake Adaptive Brake provides a high level of braking safety as well as increased braking comfort. Adaptive Brake takes driver and vehicle characteristics into consideration, thus achieving an optimal braking effect. In addiditon, Adaptive Brake provides the HOLD function (Y page 161) and the hill-start assist system (Y page 160). For more information on the brake system, see (Y page 254).
EBP G Observe Safety notes, see page 62. The Electronic Brake Proportioning (EBP) enhances braking effectiveness by allowing the rear brakes to supply a greater proportion of the braking effort in straight-line braking without a loss of vehicle stability. G Warning! If the EBP malfunctions, the brake system will still function with full brake boost. However, the rear wheels could lock up during emergency braking situations, for example. You could lose control of the vehicle and cause an accident. Adapt your driving style to the changed driving characteristics.

Version: 2.11.8.1ESC G Observe Safety notes, see page 62. The Electronic Stability Control (ESC) is operational as soon as the engine is running. It monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling. The ESC recognizes that the vehicle deviates from the direction of travel as intended by the driver. By applying brakes to individual wheels and by limiting the engine output, the ESC works to stabilize the vehicle. The ESC is especially useful while driving off and on wet or slippery road surfaces. The ESC also stabilizes the vehicle during braking and steering maneuvers. The ESC warning lamp ä in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running. G Warning! Never switch off the ESC when you see the ESC warning lamp ä flashing in the instrument cluster. In this case proceed as follows: RWhen driving off, apply as little throttle as
possible.
RWhile driving, ease up on the accelerator
pedal.
RAdapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could cause the vehicle to skid. The ESC cannot prevent accidents resulting from excessive speed.
! Vehicles with 4MATIC: Because the ESC
operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS- GO start/stop button in position 0 or 1) when the parking brake is being tested on a brake test dynamometer.

Active braking action through the ESC may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.
! Vehicles without 4MATIC: Because the ESC operates automatically, the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS- GO start/stop button in position 0 or 1) when the parking brake is being tested on a brake test dynamometer or when the vehicle is being towed with one axle raised. Active braking action through the ESC may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.
! The ESC will only function properly if you use wheels of the recommended tire size as specified in the “Technical data” section of this Operator’s Manual.
i The DISTRONIC PLUS and cruise control
switch off automatically when the ESC engages.
Electronic Traction System (ETS/4-ETS) G Observe Safety notes, see page 62. The ETS (Electronic Traction System) and 4-ETS (four-wheel Electronic Traction System, vehicles with 4MATIC only) are components of the ESC. The ETS/4-ETS improves the vehicle’s ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. Vehicles with 4MATIC also transfer more power to the wheel(s) with traction. When you switch off the ESC, the ETS/4-ETS is still enabled.

Switching the ESC off or on (except E 63 AMG) G Warning! The ESC should not be switched off during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers. Do not switch off the ESC when a spare wheel is mounted. To improve the vehicle’s traction, switch off the ESC. This allows the drive wheels to spin and thus cut into surfaces for better grip, for example Rwhen driving with snow chains Rin deep snow Rin sand or gravel G Warning! Switch on the ESC immediately if the aforementioned circumstances do not apply anymore. Otherwise the ESC will not stabilize the vehicle when it is starting to skid or a wheel is spinning.
