front passenger have fastened their seat belts. If the driver's seat belt is not fastened after the engine is started, an additional warning tone will sound. The warning tone goes out after approximately six seconds or once the driver's seat belt is fastened. If the driver or front passenger have not fastened their seat belt after 6 seconds and the doors are closed, the 7 seat belt warning lamp lights up. Runtil the driver or the front passenger have
fastened their seat belts
Rif a vehicle speed of 15 mph(25 km/h) is
exceeded once, a warning tone with increasing intensity sounds additionally for a maximum of 60 seconds or until the driver or front passenger have fastened their seat belts.
If the driver or front passenger undo their seat belts during the journey, the 7 seat belt warning lamp lights up and the warning tone sounds again. The warning tone ceases even if the driver or front passenger have still not fastened their seat belt after 60 seconds. The 7 seat belt warning lamp stops flashing but continues to be lit. Once the vehicle is stationary, the warning tone is reactivated and the 7 seat belt warning lamp starts to flash again if the vehicle speed exceeds 15 mph(25 km/h) once.

Emergency Tensioning Devices, belt force limiters The front seat belts and the outer seat belts in the rear are equipped with ETDs and seat belt force limiters. The ETDs tighten the seat belts in an accident, pulling them close against the body. The ETDs do not correct incorrect seat positions or incorrectly fastened seat belts. The ETDs do not pull vehicle occupants back towards the backrest. Seat belt force limiters, when triggered, help to reduce the peak 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. These 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 when: Rthe ignition is switched on. Rthe restraint systems are operational; see
"SRS warning lamp" (Y page 38).
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: Rif, in the event of a head-on or rear-end
collision, the vehicle decelerates or accelerates rapidly in a longitudinal direction during the initial stages of the impact
Rif, in the event of a side impact, on the side
opposite the impact the vehicle
decelerates or accelerates rapidly in a lateral direction
Rif, in certain situations where the vehicle overturns, the system determines that it can provide additional protection
If the air bags are deployed, 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.
! 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.
Children in the vehicle Child restraint systems Important safety notes We recommend that all infants and children be properly secured in an infant or child restraint system at all times while the vehicle is in motion. 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. Infants and children must always be seated in an appropriate infant or child restraint systemrecommended for the size and weight of the child. The infant or child restraint system must be properly secured in accordance with the manufacturer's instructions. All infant or child restraint systems must meet U.S. Federal Motor Vehicle Safety Standards 213
and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2. An information label on the child restraint system indicates whether it meets these standards. This information is also provided in the installation instructions supplied with the child restraint system. Always read and follow the manufacturer's instructions when using an infant or child restraint system or booster seat. Observe all warning signs in the vehicle interior and on the infant or child restraint. 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 in the vehicle

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: RYour 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.
RFor 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 4 5 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated.
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 4 5 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 4 5 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 4 5 indicator lamp while driving to make sure the 4
5 indicator lamp is illuminated. If the 4 5 indicator lamp goes out or remains out, do not transport a child on the front passenger seat until the system has been repaired.58
Children in the vehicle
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 the shoulder belt across the 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.
If an infant or child is traveling in the vehicle: X Secure the infant or child with an
appropriate infant or child restraint recommended for the child's age and weight.
X Make sure that the infant or child is
properly secured at all times while the vehicle is in motion.

Driving safety systems Driving safety systems overview In this section, you will find information about the following driving safety systems: RABS (Anti-lock Braking System) RBAS (Brake Assist System) RBAS PLUS (Brake Assist System Plus*) RESP® (Electronic Stability Program) REBD (Electronic Brake force Distribution) RADAPTIVE BRAKE RPRE-SAFE® Brake
Important 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.
i Please note that the driving safety
systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Pay particular attention to the information regarding tires, recommended minimum tire tread depths etc. in the "Wheels and tires" section (Y page 346). 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.
64 Driving safety systems
ABS (Anti-lock Braking System) Important safety notes i Observe the "Important safety notes"
section (Y page 63).
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. 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 ! 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.
The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving. 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.
BAS (Brake Assist System) i Observe the "Important safety notes"
section (Y page 63).
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 System Plus) BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS. i Observe the "Important safety notes"
section (Y page 63).
At speeds above approximately 4 mph (7 km/h), BAS PLUS assists you when braking in hazardous situations and uses the radar sensor system to evaluate the traffic conditions. i This device 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. Removing, altering or tampering with 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.
With the help of the radar sensor system, BAS PLUS can detect obstacles that are in the path of your vehicle for an extended period of time. At speeds up to approximately 40 mph (70 km/h), BAS PLUS can also detect stationary obstacles, for example stopped or parked vehicles. Should you approach an obstacle and BAS PLUS has detected a risk of collision, BAS PLUS calculates the braking force necessary to avoid a rear-end collision. RAt speeds up to approximately
20 mph(30 km/h): should you apply the brakes forcefully, BAS PLUS will automatically increase the braking force to a level suitable for the traffic conditions.
RAt speeds up to approximately
20 mph(30 km/h): should you apply the brakes, BAS PLUS is activated. Braking is performed as late as possible.
If BAS PLUS demands particularly high braking force, preventative passenger protection measures (PRE-SAFE®) are 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 if: Ryou release the brake pedal. Rthere is no longer any danger of a rear-end
collision.
Rno obstacle is detected in front of your
vehicle.
BAS PLUS is then deactivated. For BAS PLUS to assist you when driving, the radar sensor system must be switched on and operational, see "Radar sensor system" in the index.
Driving safety systems
65
G WARNING BAS PLUS cannot always clearly identify objects and complex traffic situations. BAS PLUS cannot intervene in these cases. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.
In particular, the detection of obstacles can be impaired if there is: Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain Rinterference by other radar sources Rthe possibility of 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 G WARNING BAS PLUS does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rin curves As a result, BAS PLUS cannot intervene in critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.
Following damage to the front end of the vehicle, have the configuration and operation of the radar sensors checked at a qualified specialist workshop. This also applies to collisions at low speeds where there is no visible damage to the front of the vehicle. 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.
66 Driving safety systems
ESP® (Electronic Stability Program) Important safety notes i See the "Important safety notes" section
(Y page 63).
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.
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 ÷ ESP® warning lamp flashes in the instrument cluster. G WARNING Under no circumstances should you deactivate ESP® when the ÷ ESP® warning lamp in the instrument cluster flashes. Proceed as follows: Rwhen driving off, apply as little throttle as
possible.
Rwhile driving, ease up on the accelerator
pedal.
Radapt your speed to suit the prevailing road
and weather conditions.
Failure to observe these guidelines could cause the vehicle to skid. 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.
ETS/4ETS (Electronic Traction System) G WARNING Observe "Important safety notes" (Y page 63).
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 ESP® should not be deactivated during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers. Do not deactivate ESP® when the emergency or spare wheel is mounted.
ESP® is activated automatically when the engine is started. 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 ESP® immediately if one of the previously stated conditions is no longer met.
Driving safety systems
67
Otherwise, ESP® cannot stabilize the vehicle if it begins to lurch or when a wheel spins.
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.
Rtraction control is still activated. RESP® still provides support when you
brake.
If ESP® is deactivated and one or more wheels start to spin, the ÷ ESP® warning lamp in the instrument cluster flashes. In such situations, ESP® will not stabilize the vehicle. X To deactivate:(Y page 224).
The å ESP® OFF warning lamp in the instrument cluster lights up. G WARNING When the å ESP® OFF warning lamp is lit, ESP® is deactivated. If the ÷ ESP® warning lamp and the å ESP® OFF warning lamp remain lit, ESP® is not available due to a malfunction. When ESP® is deactivated or not operational, 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®.
! Avoid spinning the driven wheels for an extended period with ESP® deactivated. You could otherwise damage the drivetrain.
X To activate:(Y page 224).
The å ESP® OFF warning lamp in the instrument cluster goes out.
Deactivating/activating ESP® (AMG vehicles) Activating/deactivating SPORT handling mode G WARNING The SPORT handling mode should not be switched on during normal driving. Switching on the SPORT handling mode will result in the following: Rno restriction to the engine torque Rsystem supported traction control is
limited
The SPORT handling mode is designed for driving on closed tracks when the vehicle's own natural oversteer and understeer characteristics are desired and requires a highly skilled and experienced driver able to handle these critical driving situations. You could lose control of your vehicle and cause an accident. Please be aware of these limits when you switch on the SPORT handling mode. Do not switch on the SPORT handling when a spare wheel is mounted.
ESP® is activated automatically when the engine is started. It may be best to activate SPORT handling mode in the following situations: Rwhen using snow chains Rin deep snow Ron sand or gravel G WARNING Switch off the SPORT handling mode and switch on the ESP® immediately if the aforementioned circumstances do not apply anymore. Otherwise the SPORT handling mode will only stabilize the vehicle to a limited extent when it is starting to skid or a wheel is spinning.
68 Driving safety systems
When SPORT handling mode is activated: RESP® only improves driving stability to a
limited degree.
Rthe engine's torque is restricted only to a limited degree and the drive wheels can spin. The spinning of the wheels results in a cutting action, which provides better grip.

Activating/deactivating ESP® G WARNING The ESP® should not be switched off during normal driving. Disabling of the system will result in the following: Rno restriction to engine torque Rloss of system-supported traction control
"ESP® OFF" is designed for driving on closed tracks when the vehicle's natural oversteer and understeer characteristics are desired and requires a highly skilled and experienced driver able to handle these critical driving situations. You could lose control of your vehicle and cause an accident. Please be aware of these limits when you switch off the ESP®. Do not switch off the ESP® when a spare wheel is mounted.
ESP® is activated automatically when the engine is started. 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 ESP® immediately if one of the previously stated conditions is no longer met. Otherwise, ESP® cannot stabilize the vehicle if it begins to lurch or when a wheel spins.
If you deactivate ESP®: RESP® no longer improves driving stability. Rthe engine's torque is no longer limited and
the drive wheels are able to spin. The spinning of the wheels results in a cutting action, which provides better grip.
Rtraction control is still activated. RPRE-SAFE® is no longer available, nor is it
activated if you brake firmly and ESP® intervenes.
RPRE-SAFE® Brake is no longer available, nor is it activated if you brake firmly and ESP® intervenes.

EBD (electronic brake force distribution) i Observe the "Important safety notes"
section (Y page 63).
EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking. G WARNING If EBD has malfunctioned, the braking system remains available with full brake boosting effect. However, the rear wheels can still lock, e.g. under full braking. This could cause you to lose control of your vehicle and cause an accident. You should therefore adapt your driving style to the different handling 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 187) and hill start assist (Y page 148). For further information, see Driving tips (Y page 171).
PRE-SAFE® Brake PRE-SAFE® Brake is only available in vehicles with DISTRONIC PLUS. i Observe the "Important safety notes"
section (Y page 63).
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. If PRE-SAFE® Brake has detected a risk of collision, you will be warned visually and acoustically as well as by automatic braking. PRE-SAFE® Brake cannot prevent a collision without your intervention. At speeds above approximately 4 mph (7 km/h), this function warns you
70 Driving safety systems
when you are rapidly approaching the vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp in the instrument cluster will light up. 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.
If the driver and front passenger have their seat belt fastened, PRE-SAFE® Brake can also brake the vehicle automatically at speeds from approximately 4 mph (7 km/h) to approximately 124 mph (200 km/h). Due to the nature of the system, particularly complicated driving conditions may cause unnecessary warnings or the unnecessary intervention of PRE-SAFE® Brake. To stop the braking action, you can either depress the accelerator pedal further, activate kickdown or release the brake pedal. The braking action of PRE-SAFE® Brake is ended automatically if: Ryou maneuver to avoid the obstacle. Rthere is no longer any danger of a rear-end
collision.
Rthere is no longer an obstacle detected in
front of your vehicle.
i USA only: this device 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. Removing, altering or tampering with 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.
i Canada only: this device complies with RSS-210 of Industry Canada. Operation is subject to the following two conditions: 1. This device may not cause interference, and
2. this device must accept any interference received, including interference that may cause undesired operation of the device. Removal, tampering, or altering of the device will void any warranties, and is not permitted. 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.
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. At speeds up to approximately 40 mph (70 km/h), PRE-SAFE® Brake can also react to stationary obstacles, for example stopped or parked vehicles. If you approach an obstacle and PRE-SAFE® Brake detects a risk of collision, the system will initially alert you both visually and acoustically. If you do not brake or take evasive action, the system will warn you by automatically braking the vehicle gently. If there is an increased risk of collision, preventative passenger protection measures (PRE-SAFE®) are activated (Y page 50). If the risk of collision remains at speeds of over 20 mph(30 km/h) and you do not brake, take evasive action or accelerate significantly, the vehicle may perform automatic braking up to emergency braking. Automatic emergency braking is not performed until immediately prior to an accident that can no longer be avoided. G WARNING Even if PRE-SAFE® Brake slows the vehicle before an imminent rear-end collision, the system cannot avert a collision without the intervention of the driver. There is a risk of an accident. Brake according to the situation or take evasive action. Delayed intervention by the driver can lead to an accident.
G WARNING PRE-SAFE® Brake cannot always detect complex traffic situations properly. In these cases, PRE-SAFE(R) Brake may: Rgive an unnecessary warning and then
brake the vehicle
Rneither give a warning nor 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(R) Brake warns you. Terminate the intervention in a non-critical driving situation.
In particular, the detection of obstacles can be impaired if there is: Rdirt on the sensors or anything else
covering the sensors
Rsnow or heavy rain Rinterference by other radar sources Rthe possibility of 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 G WARNING PRE-SAFE® Brake does not react: Rto people or animals Rto oncoming vehicles Rto crossing traffic Rin curves As a result, PRE-SAFE® Brake cannot intervene in critical situations. There is a risk of an accident. Always pay careful attention to the traffic situation and be ready to brake.
In order to maintain the appropriate distance to the vehicle in front and thus prevent a collision, you must apply the brakes yourself.
