Rin side impacts exceeding the system’s preset deployment threshold on the far side of the impact Rin certain vehicle rollovers Rif the restraint systems are operational and functioning correctly, see 1 indicator lamp (Y page 45) The ETDs for the front seats will only activate if the front seat belts are fastened (latch plate properly inserted into buckle). The ETDs for the rear outer seats (second-row seats) or rear seats (third-row seats) will activate with or without the respective seat belts fastened. In an impact, the ETDs remove slack from the seat belts in such a way that the seat belts fit more snugly against the body. Seat belt force limiters, when activated, are employed to help reduce the peak force exerted by the seat belts on occupants during a crash. i The ETDs do not correct an incorrect seat position or incorrectly worn seat belts. The ETDs do not pull occupants back toward the seat backrest. G Warning! Pyrotechnic ETDs that were activated must be replaced. For your safety, when disposing of the pyrotechnic ETDs always follow our safety instructions. These are available at any authorized Mercedes-Benz Center. PRE-SAFE® has electrically operated reversible pre-tensioners that do not require replacement after activation. Preventive occupant safety (PRE- SAFE®) G Warning! PRE-SAFE® is intended to reduce the effects of an accident on vehicle occupants who are wearing their seat belt properly. Despite having the PRE-SAFE® system in your vehicle, the possibility of injuries occurring as a result of an accident cannot be eliminated. Therefore, you should always drive carefully and adjust your driving to the prevailing road, weather, and traffic conditions. Your vehicle takes preventive measures to better protect the occupants in the following hazardous situations automatically. PRE-SAFE® takes action in Remergency braking maneuvers with the Brake Assist System (BAS) (Y page 77) activated Rcritical dynamic driving situations, e.g. when the vehicle is understeering or oversteering because it has exceeded its physical limitations When you are driving faster than 22 mph (35 km/h), PRE-SAFE® takes the following measures in such situations: RThe front seat belts are pre-tensioned automatically. RVehicles with front passenger seat memory function: If the passenger seat is in an unfavorable position, it will be adjusted to a better position. RIf the vehicle is in a severe skid or is spinning, the door windows close until only a small gap remains. RVehicles with power tilt/sliding sunroof: If the vehicle is in a severe skid or is spinning, the tilt/sliding sunroof also close until only a small gap remains. Safety and security Occupant safety If the closing procedure of the door windows or tilt/sliding sunroof is blocked, the door windows or tilt/sliding sunroof will stop and open slightly. Once the hazardous situation is over without an accident occurring, the seat belt pre- tensioning is deactivated. You can readjust all of the settings made by PRE-SAFE®. If the seat belts do not release: X Adjust the seat backrest or seat slightly to the rear until the seat belt tension is diminished. The locking mechanism releases. ! When moving the seats, make sure there are no items in the footwell or behind the seats. Otherwise, you could damage the seats. 63 Correct driver seat adjustment G Warning! In order to avoid possible loss of vehicle control all seat, head restraint, steering wheel, and rear view mirror adjustments, as well as fastening of seat belts, must be done before the vehicle is put into motion. Safety and security Occupant safety Active head restraints The active 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 active head restraints on the driver’s and front passenger’s seat are designed to move forward in the direction of travel, providing the head with increased support earlier on in the collision sequence. The active head restraints move forward whether the seat is occupied or not. G Warning! Do not attach any objects (e.g. hangers) to the head restraint posts. Otherwise, the active 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. If the active head restraints have been triggered in an accident, the active head restraints must be reset. Otherwise, the active head restraints cannot offer any additional protection in the event of another rear-end collision. For information on resetting the activated active head restraints, see “Resetting activated head restraints” (Y page 354). 64 You cannot remove the active head restraint on the driver’s and front passenger’s seats. 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 active head restraints and/or the deployment of the front side impact air bags. Contact an authorized Mercedes-Benz Center for availability. 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 restraints” (Y page 100). page 97. G Observe Safety notes, see Observe the following points: RAlways be in a properly seated position. RThe position should be as far rearward from the front air bag in steering wheel 1 as possible, while still permitting proper operation of vehicle controls. 1 Steering wheel 2 Seat belt 3 Seat X Position seat 3 (Y page 98) and head restraint properly (Y page 100). RAdjust seat 3 to a comfortable seating position that still allows you to reach the accelerator/brake pedal safely.

RPlace the lap portion of seat belt 2 as low as possible on your hips. 65 Safety and security Occupant safety Children in the vehicle Safety notes If an infant or child is traveling with you in the vehicle: X Secure the child using an infant or child restraint appropriate to the age and size of the child. X Make sure the infant or child is properly secured at all times while the vehicle is in motion. 66 G Warning! When leaving the vehicle, always remove the SmartKey from the starter switch. Always take the SmartKey with you and lock the vehicle. Do not leave children unattended in the vehicle, even if they are secured in a child restraint system, or with access to an unlocked vehicle. A child’s unsupervised access to a vehicle could result in an accident and/or serious personal injury. The children could Rinjure themselves on parts of the vehicle Rbe seriously or fatally injured through excessive exposure to extreme heat or cold Rinjure themselves or cause an accident with vehicle equipment that can be operated even if the SmartKey is removed from the starter switch or removed from the vehicle, such as seat adjustment, steering wheel adjustment, or the memory function. If children open a door, they could injure other persons or get out of the vehicle and injure themselves or be injured by following traffic. Do not expose the child restraint system to direct sunlight. The child restraint system’s metal parts, for example, could become very hot, and the child could be burned on these parts. G Warning! Do not carry heavy or hard objects in the passenger or cargo compartment unless they are firmly secured in place. Unsecured or improperly positioned cargo increases a child’s risk of injury in the event of Rstrong braking maneuvers Rsudden changes of direction Ran accident For more information on loading, please refer to the “Loading and storing” (Y page 206) chapter. Infant and child restraint systems G Observe Safety notes, see We recommend all infants and children be properly restrained at all times while the vehicle is in motion. page 66. Canada only: Only use a BabySmartTM compatible child restraint for the front passenger seat in this vehicle. All lap/shoulder belts except the driver’s seat belt have special seat belt retractors for secure fastening of child restraints. To fasten a child restraint, follow child restraint instructions for mounting. Then pull the shoulder belt out completely and let it retract. During seat belt retraction, a ratcheting sound can be heard to indicate that the special seat belt retractor is activated. The seat belt is now locked. Push down on child restraint to take up any slack. To deactivate, release the seat belt buckle and let the seat belt retract completely. To deactivate the special seat belt retractor for the front passenger seat, the front passenger seat must be in the most backward position. The seat belt can again be used in the usual manner. G Warning! Never release the seat belt buckle while the vehicle is in motion, since the special seat belt retractor will be deactivated. i Information on child seats with mounting fittings for tether anchorages (Y page 69). For information on LATCH-type child seat anchors (Y page 72). 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, properly secured in accordance with the manufacturer’s instructions for the child restraint, that complies 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. Safety and security Occupant safety 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. 67 Safety and security Occupant safety 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 59 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 BabySmartTM compatible child seat, which operates with the BabySmartTM system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. 68 Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result. RA 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 59 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 59 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 59 indicator lamp while driving to make sure the 59 indicator lamp is illuminated. If the 59 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.

Safety and security Driving safety systems Driving safety systems Introduction This section contains information about the following driving safety systems: RABS (Antilock Brake System) RBAS (Brake Assist System) REBP (Electronic Brake Proportioning) RESP® (Electronic Stability Program) 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 75 Safety and security Driving safety systems 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. 76 ABS G Observe Safety notes, see page 75. 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 - 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, indicating 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. G Warning! If the ABS malfunctions, other driving safety systems such as the BAS or the ESP® 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. For more information, see “What to do if …?” (Y page 341). page 75. BAS G Observe Safety notes, see The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS automatically provides full brake boost, 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. page 75. EBP G Observe Safety notes, see 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. Safety and security Driving safety systems ESP® G Observe Safety notes, see page 75. The Electronic Stability Program (ESP®) is operational as soon as the engine is running and monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling. The ESP® recognizes when a wheel is spinning or if the vehicle starts to skid. By applying brakes to individual wheels and by limiting the engine output, the ESP® works to stabilize the vehicle. The ESP® is especially useful while driving off and on wet or slippery road surfaces. The ESP® also stabilizes the vehicle during braking and steering maneuvers. The ESP® warning lamp v in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running. The ESP® warning lamp v in the instrument cluster flashes when the ESP® is engaged. 77 Safety and security Driving safety systems G Warning! Never switch off the ESP® when you see the ESP® warning lamp v 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 ESP® cannot prevent accidents resulting from excessive speed. ! Only conduct operational or performance tests on a two-axle dynamometer. If such tests are necessary, contact an authorized Mercedes-Benz Center. You could otherwise seriously damage the brake system or the transfer case which is not covered by the Mercedes-Benz Limited Warranty. ! Because the ESP® operates automatically, the engine and ignition must 78 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. Such testing should be no longer than 10 seconds. Active braking action through the ESP® may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty. ! The ESP® 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 cruise control switches off automatically when the ESP® engages. For more information, see the “Practical hints” section (Y page 306) and (Y page 346). Electronic Traction System (4-ETS) G Observe Safety notes, see The 4-ETS (four-wheel Electronic Traction System) are components of the ESP®. The 4-ETS improves the vehicle’s ability to utilize page 75. available traction, especially under slippery road conditions by applying the brakes to a spinning wheel. In addition, more power is transferred to the wheel(s) with traction. When you switch off the ESP®, the 4-ETS is still enabled. Switching off the ESP® G Warning! The ESP® 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 ESP® when a spare wheel is mounted. To improve the vehicle’s traction, switch off the ESP® in driving situations in which it would be advantageous to have the drive wheels spin and thus cut into surfaces for better grip such as: Rwhen driving with snow chains Rin deep snow Rin sand or gravel G Warning! Switch on the ESP® immediately if the aforementioned circumstances do not apply anymore. Otherwise the ESP® will not stabilize the vehicle when it is starting to skid or a wheel is spinning. When you switch off the ESP® Rthe ESP® does not stabilize the vehicle Rthe engine output is not limited, which allows the drive wheels to spin and thus cut into surfaces for better grip Rthe 4-ETS will still apply the brakes to a spinning wheel Rthe ESP® continues to operate when you are braking Ryou cannot activate the cruise control Rthe cruise control switches off if activated i When the ESP® is switched off and one or more drive wheels are spinning, the ESP® warning lamp v in the instrument cluster flashes. However, the ESP® will then not stabilize the vehicle. 1 ESP® switch X With the engine running, press ESP® switch 1 until the ESP® warning lamp v in the instrument cluster comes on. The ESP® is switched off. G Warning! When the ESP® warning lamp v is illuminated continuously, the ESP® is switched off or is not operational due to a malfunction. Vehicle stability in standard driving maneuvers is reduced. Adapt your speed and driving to the prevailing road conditions and to the non- operating status of the ESP®. Safety and security Driving safety systems ! Avoid spinning of a drive wheel for an extended period with the ESP® switched off. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty. Switching on the ESP® X Press ESP® switch 1 until the ESP® warning lamp v in the instrument cluster goes out. You are now again in normal driving mode with the ESP® switched on. ESP® trailer stabilization If the trailer you are towing should begin to sway, the rig can only be stabilized by immediately applying the brakes hard. Steering during this maneuver will not help to stabilize the rig. The ESP® will assist you in such situations. The ESP® recognizes when the trailer starts swaying and will apply the brakes to reduce the vehicle speed to a non-critical speed that allows the vehicle-trailer combination to stabilize. 79 Safety and security Anti-theft systems The ESP® trailer stabilization is functional at vehicle speeds above approximately 40 mph (65 km/h) when the ESP® is switched on.
