Version: 3.0.3.6G 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.
Resetting triggered NECK-PRO head restraints G Warning For safety reasons, have the NECK-PRO head restraints checked at an authorized Mercedes-Benz Center after a rear-end collision. G Warning When pushing back the NECK-PRO head restraint cushion, make sure your fingers do not become caught between the head restraint cushion and the cover. Failure to observe this could result in injuries.
i Resetting the NECK-PRO head restraints
requires a lot of strength. If you have difficulty resetting the NECK-PRO head restraints, have this work carried out at a qualified specialist workshop, e.g. an authorized Mercedes-Benz Center.

Seat belts Important 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 when the vehicle is in motion. i See "Children in the vehicle"(Y page 58) for more information on infants and children traveling with you in the vehicle and restraints 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 seat belt provide the best restraint when the wearer is in a position that is as upright as possible and the seat belt is properly positioned on the body. G Warning 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 and their anchoring points must also 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.
Correct use of the seat belt G Warning USE SEAT BELTS PROPERLY RSeat belts can only work 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 the event 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's side knee bag, front-passenger front air bag, side impact air bags, pelvis air bags, window curtain air bags for the side windows), Emergency Tensioning Devices, 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, 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, across 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.

Version: 3.0.3.6RPosition 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.
RNever use a seat belt for more than one
person at a time. Do not fasten a seat belt around a person and another person or other objects at the same time.
RSeat belts should not be worn twisted. In a crash, you would not have the full width of the seat belt to distribute impact forces. The twisted seat belt against your body could cause injuries.
RPregnant women should also always use a
lap-shoulder belt. The lap belt portion should be positioned as low as possible on the hips to avoid any possible pressure on the abdomen.
RPlace the seat backrest in a position that is
as upright as possible.
RCheck your seat belt during travel to make
sure it is properly positioned.
RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.
RWhen using a seat belt to secure infant
restraints, toddler restraints, or children in booster seats, always follow the child seat manufacturer's instructions. G Warning Do not pass seat belts over sharp edges. They could tear. Do not allow the seat belt to get caught in the door or in the seat adjustment mechanism. This could damage the seat belt.

Never attempt to make modifications to seat belts. This could impair the effectiveness of the seat belts.
Fastening seat belts G Warning According to accident statistics, children are safer when properly restrained on the rear seats than on the front-passenger seat. Thus, we strongly recommend that children be placed in the rear seat whenever possible. Regardless of seating position, children 12
years old and under must be seated and properly secured in an appropriately sized child restraint system or booster seat recommended for the size and weight of the child. For additional information, see the "Children in the vehicle" section. 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. G Warning Canada only: children 12 years old and under may ride on the front seat if a BabySmart™ compatible child restraint system is installed on the front-passenger seat. Use only Mercedes-Benz approved BabySmart™ compatible child restraint systems. A BabySmart™ compatible child restraint system will deactivate the front-passenger front air bag when installed correctly. The front-passenger front air bag will not be deactivated if the child restraint systems that are installed are not BabySmart™ compatible or if BabySmart™ compatible child restraint systems are not installed correctly. If the front-passenger front air bag is deployed in a collision, the child will be struck by the air bag. If this happens, serious or fatal injury will result.BA 212 USA, CA Edition B 2011; 1; 5, en-US dimargi

! If the front-passenger seat is not
occupied, do not engage the seat belt tongue in the buckle on the front- passenger seat. Otherwise, the Emergency Tensioning Device could be triggered in the event of an accident.
The ETDs tighten the seat belts in an accident, pulling them close against the body. ETDs do not correct incorrect seat positions or incorrectly fastened seat belts. ETDs do not pull vehicle occupants back towards the backrest. Seat belt force limiters, when activated, are employed to help reduce the force exerted by the seat belts on occupants during a crash. The front belt force limiters are synchronized with the front air bags, which take on a part of the deceleration force. Thus, the force exerted on the occupant is distributed over a greater area. The ETDs can only be activated if: Rthe ignition is switched on. Rthe restraint systems are operational; see
"SRS warning lamp" (Y page 36).
Rthe belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front. Rthe front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side.
The ETDs on the outside seats in the rear compartment are triggered independently of the lock status of the seat belts. The ETDs are triggered depending on the type and severity of an accident: Rin the event of a head-on or rear-end collision if the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact
Rin the event of a side impact, on the side
opposite the impact if the vehicle
decelerates or accelerates rapidly in a lateral direction
Rin certain situations if the vehicle overturns
and the system determines that it can provide additional protection
If the Emergency Tensioning Devices (ETDs) are triggered, you will hear a bang, and a small amount of powder may also be released. Only in rare cases will the bang affect your hearing. The powder that is released generally does not constitute a health hazard. The 6 SRS warning lamp lights up. G Warning Pyrotechnic Emergency Tensioning Devices that have been deployed must be renewed. For your safety, when disposing of Emergency Tensioning Devices, always observe the safety instructions. These are available from any authorized Mercedes-Benz Center. The PRE-SAFE® system has electrically operated reversible pre-tensioners that do not require replacement after activation.

Child restraint systems Important safety notes G Warning Observe "Important safety notes" (Y page 58). We recommend all infants and children be properly restrained using the child restraint systems at all times while the vehicle is in motion. 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 always be seated in an infant or child seat restraint system appropriate for the size and weight of the child. They must be properly secured in accordance with the manufacturer's installation instructions for the infant or child seat restraint system. All infant and child seat restraint systems must comply with the US 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 system. You will also find the statement in the instruction manual provided with the child restraint system. When using an infant restraint system, child restraint system or booster seat, make sure to carefully read and follow all manufacturer's instructions for installation and use. Please read the warning labels affixed to the interior of the vehicle or to the infant restraint or child restraint system. G Warning Accident statistics show that children secured in the rear seats are safer than children secured in the front-passenger seat. For this reason, we strongly advise that you always secure children in the rear seats. Regardless of the seat position, children under 12 years must be secured correctly in a suitable infant or child restraint system or booster seat suitable for the size and weight of the child. The infant or child restraint system must be correctly secured using the vehicle's seat belt, the seat belt and Top Tether belt or the lower anchorages and the Top Tether belt in complete accordance with the child seat manufacturer's instructions.

system, child restraint system or booster seat suitable for the size and weight of the child. Children can be seriously or even fatally injured by an air bag deploying. Observe the following important information if it is absolutely necessary to carry a child on the front-passenger seat: RUSA only: Your vehicle is equipped with air
bag technology that is designed to deactivate the front-passenger front air bag, when the system on the front- passenger seat detects the weight of a typical 12-month old child in a standard child restraint.
RUSA only: For children that weigh more
than a typical 12-month old child, the front- passenger front air bag can be activated or deactivated. Always make sure that the 45 indicator lamp is illuminated indicating that the front-passenger front air bag is deactivated.
RCanada only: Children 12 years old and
under may ride on the front seat if a BabySmart™ compatible child restraint system is installed on the front-passenger seat. Use only Mercedes-Benz approved BabySmart™ compatible child restraint systems. A BabySmart™ compatible child restraint system will deactivate the front- passenger front air bag when installed correctly. The front-passenger front air bag will not be deactivated if the child restraint systems that are installed are not BabySmart™ compatible or if BabySmart™ compatible child restraint systems are not installed correctly. If the front-passenger front air bag is deployed in a collision, the child could be struck by the air bag. This could lead to serious or fatal injury.
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 way to completely
rule out this risk is by making sure you never place a child in a rearward-facing child restraint system on the front- passenger seat. For this reason, we strongly advise that you always carry children in a rearward-facing child restraint system on a rear seat.
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. If the 45 indicator lamp does not light up or goes out when the child restraint system is installed, check the anchorages of the restraint system. Check the 45
indicator lamp regularly while driving to ensure that the 45 indicator lamp is illuminated. If the 45 indicator lamp goes out or remains out, you may only carry a child on the front-passenger seat once 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.Rwhen securing a child in a child restraint system on the front-passenger seat, you must: - move the front-passenger seat as far
back as possible
- use a child restraint system that is
suitable for the age, size and weight of the child
- observe the manufacturer's installation instructions in order to install and secure the child restraint system correctly.
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

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.
i In wintry driving conditions, always use winter 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) Important safety notes G Warning Observe "Important safety notes" (Y page 65). 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.
ABS regulates brake pressure in such a way that the wheels do not lock when you brake. This allows you to continue steering the vehicle when braking. ABS works from a speed of about 5 mph (8 km/h) upwards, regardless of road- surface conditions. ABS works on slippery surfaces, even when you only brake gently.

The ! warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out when the engine is running.
Braking If ABS intervenes when braking, you will feel a pulsing in the brake pedal. X If ABS intervenes: continue to depress the
brake pedal with force until the braking situation is over.
X To make a full brake application:
depress the brake pedal with full force. G Warning If the ABS malfunctions, other driving 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 the steering capability and extending the braking distance.
The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.
BAS (Brake Assist) G Warning Observe "Important safety notes" (Y page 65). BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance. 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.
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 (Brake Assist PLUS) G Warning Observe "Important safety notes" (Y page 65). At speeds above approximately 20 mph (30 km/h), BAS PLUS assists you when braking in hazardous situations and uses the radar sensor system to evaluate the traffic conditions. 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 equipment has been approved by the
FCC as a "Vehicular Radar System". The radar sensor system 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 the device in any way. Any unauthorized modification to this device could void the user's authority to operate the equipment.

Version: 3.0.3.6BAS PLUS can detect obstacles that are in the path of your vehicle for an extended period of time. Should you approach a detected obstacle quickly, BAS PLUS calculates the braking force necessary to avoid a rear-end collision. Should you additionally apply the brakes, BAS PLUS will automatically increase the braking force to a level suitable for the traffic conditions. If BAS PLUS demands particularly high braking force, PRE-SAFE® is activated simultaneously. 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 when: Ryou release the brake pedal Rno obstacle is detected in front of your
vehicle
Rthere is no longer any danger of a rear-end
collision
BAS PLUS is then deactivated. At speeds up to approximately 40 mph (70 km/h), BAS PLUS can also detect stationary obstacles, for example, stopped or parked vehicles. For BAS PLUS to assist you when driving, the radar sensor system must be switched on and operational. You can check this by activating DISTRONIC PLUS (Y page 179) or via the "radar sensor" function in the on-board computer(Y page 232). 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.
Following a collision or accident-related damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at an authorized Mercedes- Benz Center. If BAS PLUS is not available due to a malfunction in the radar sensor system, the brake system remains available with full brake boosting effect and BAS.
ESP® (Electronic Stability Program) Important safety notes G Warning Observe "Important safety notes" (Y page 65).
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. If necessary, 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. If ESP® intervenes, the ä warning lamp flashes in the instrument cluster.

G Warning! Never switch off the ESP when you see the ESP 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 ESP cannot prevent accidents resulting from excessive speed.
! Vehicles without 4MATIC: switch the
ignition off when: Rthe parking brake is being tested using a
dynamometer
Rthe vehicle is being towed with the front/
rear axle raised
Application of the brakes by ESP® may otherwise destroy the brake system.
! Vehicles with 4MATIC: switch off the
ignition when the parking brake is being tested on a brake dynamometer. Application of the brakes by ESP® may otherwise destroy the brake system.
i Only use wheels with the recommended
tire sizes. Only then will ESP® function properly.
ETS/4ETS (Electronic Traction System) G Warning Observe "Important safety notes" (Y page 65).
Traction control is part of ESP®. Traction control brakes the drive wheels individually if they spin. This enables you to pull away and accelerate on slippery surfaces, for example if the road surface is slippery on
one side. On vehicles with 4MATIC, more drive torque is also transferred to the wheel or wheels with traction. Traction control remains active if you deactivate ESP®.
Deactivating/activating ESP® (except AMG vehicles) 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.
ESP® is activated automatically when the engine is running. It may be best to deactivate ESP® in the following situations: Rwhen using snow chains Rin deep snow Ron 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.
If you deactivate ESP®: RESP® no longer improves driving stability. Rthe engine's torque is no longer limited and the drive wheels can spin. The spinning of the wheels results in a cutting action, which provides better grip.

Adapt your driving style to the changed driving characteristics.
Adaptive Brake ADAPTIVE BRAKE enhances braking safety and offers increased braking comfort. In addition to the braking function, ADAPTIVE BRAKE also has the HOLD function (Y page 188) and hill start assist (Y page 152). For further information, see Driving tips (Y page 173).
PRE-SAFE® Brake (vehicles with DISTRONIC PLUS) PRE-SAFE® Brake can help you to minimize the risk of a frontal collision with a vehicle ahead or reduce the effects of such a collision. This function warns you from a speed of approximately 20 mph (30 km/h) when you are rapidly approaching a vehicle in front. An intermittent warning tone sounds and the · distance warning lamp lights up in the instrument cluster. Due to the nature of the system, particularly complicated driving conditions may cause the system to display an unnecessary warning. At speeds of above approximately 20 mph (30 km/h), if the driver and passengers have fastened their seat belts, the PRE-SAFE® Brake can: Rbrake the vehicle automatically at speeds
ranging up to approximately 124 mph (200 km/h)

indicate that the PRE-SAFE® Brake will not be capable of slowing the vehicle sufficiently to maintain the preset following distance, which creates a danger of a collision. Immediately brake your vehicle to increase the distance between your vehicle and the vehicle driving in front of you. The warning sound is intended as a final caution that you have not interceded with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking, as that will result in potentially dangerous emergency braking which will not always result in an impact being avoided. Tailgating increases the risk of an accident. G Warning! The PRE-SAFE® Brake 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 the PRE-SAFE® Brake is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late and could cause an accident resulting in personal or fatal injury to you or others.

With the help of the radar sensor system, PRE-SAFE® Brake can detect obstacles that are in front of your vehicle for an extended period of time. If you approach an obstacle and PRE-SAFE® Brake detects a risk of a collision, the system will initially alert you both visually and acoustically. If you do not brake or steer, the vehicle will at first automatically brake slightly. In the event of an increased risk of a collision, PRE-SAFE® is activated (Y page 51). If the risk of collision remains and you do not brake, take evasive action or accelerate significantly, the vehicle may perform automatic emergency braking. G Warning!
