SRS (Supplemental Restraint System)

Introduction

SRS consists of:

R 6 SRS warning lamp

Air bags

Air bag control unit with crash sensors

Emergency Tensioning Devices

Belt force limiters

SRS reduces the risk of occupants coming into contact with the vehicle's interior in the event of an accident. It can also reduce the effect of the forces to which occupants are subjected during an accident.

SRS warning lamp

G WARNING

The SRS self-check has detected a malfunction if the 6 SRS indicator lamp:

R does not light up at all

R does not go out after approximately four seconds after the engine is started

R lights up after the engine is started or while the vehicle is in motion

For your safety, Mercedes-Benz strongly recommends that you have the system checked as soon as possible at a qualified specialist workshop. SRS may otherwise fail to activate when it is needed in the event of an accident, which could lead to serious or fatal injuries. SRS might also be activated unexpectedly and unnecessarily, which could also result in injury.

In addition, work carried out improperly on

SRS may render SRS inoperative or cause unintended air bag deployment. Work on the

SRS system should only be carried out by qualified specialist personnel. Consult a qualified specialist workshop.

If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center for details. USA only: for further information, contact our Customer Assistance Center at

1-800-FOR-MERCedes (1-800-367-6372).

SRS functions are checked regularly when you switch on the ignition and when the engine is running. Therefore, malfunctions can be detected in good time.

The 6 SRS warning lamp in the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the engine is started.

The SRS components are in operational readiness when the SRS 6 indicator lamp goes out while the engine is running.

Occupant safety

Safety guidelines for seat belts,

Emergency Tensioning Devices (ETDs) and air bags

G WARNING

Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Their anchoring points must also be checked. Only use seat belts installed or supplied by an authorized

Mercedes-Benz Center.

Air bags and pyrotechnic Emergency

Tensioning Devices (ETDs) contain perchlorate material, which may require special handling and regard for the environment. Check your national disposal guidelines. California residents, see www.dtsc.ca.gov/HazardousWaste/

Perchlorate/index.cfm.

Air bags and ETDs are designed to function on a one-time-only basis. An air bag or ETD that has deployed must be replaced. PRE-

SAFE ® has electrically operated reversible belt tensioners in addition to the pyrotechnic ETDs.

R Do not pass seat belts over sharp edges.

They could tear.

R Do not make any modification that could change the effectiveness of the seat belts.

R 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.

R No modifications of any kind may be made to any components or wiring of the SRS.

R Do not change or remove any component or part of the SRS.

R Do not install additional trim material, seat covers, badges, etc. to the:

padded steering wheel boss

knee bag covers front-passenger air bag cover outer side of front seat bolsters side trim next to the rear seat backrest roof lining trim

R Do not install additional electrical/ electronic equipment on or near SRS components and wiring.

R Keep area between air bags and occupants free of objects (e.g. packages, purses, umbrellas, etc.).

R Do not hang items such as coat hangers from the coat hooks or handles over the door. These items may be thrown around in the vehicle and cause head and other injuries when the window curtain air bag is deployed.

R Air bag system components will be hot after an air bag has inflated. Do not touch them.

R Never place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.

R Improper repair work on the SRS creates a risk of rendering the SRS inoperative or causing unintended air bag deployment.

Work on the SRS must therefore only be performed by qualified technicians.

Contact an authorized Mercedes-Benz

Center.

R For your protection and the protection of others, when scrapping the air bag unit or

ETD, our safety instructions must be followed. These instructions are available from any authorized Mercedes-Benz

Center.

R Given the considerable deployment speed, required inflation volume, and the material of the air bags, there is the possibility of abrasions or other, potentially more serious injuries resulting from air bag deployment.

If you sell your vehicle, Mercedes-Benz strongly recommends that you inform the subsequent owner that the vehicle is equipped with SRS. Also, refer them to the applicable section in the Operator's Manual.

Occupant safety

Air bags

Important safety notes

G WARNING

Air bags are designed to reduce the incidence of injuries and fatalities in certain situations:

R frontal impacts (driver's and frontpassenger front air bags and knee bags)

R side impacts (side impact air bags, window curtain air bags and pelvis air bags)

R rollover (window curtain air bags)

However, no system available today can completely eliminate injuries and fatalities.

When the air bags are deployed, a small amount of powder is released. The powder generally does not constitute a health hazard and does not indicate that there is a fire in the vehicle. In order to prevent potential breathing difficulties, you should leave the vehicle as soon as it is safe to do so. If you have any breathing difficulty but cannot get out of the vehicle after the air bag inflates, then get fresh air by opening a window or door.

G WARNING

In order to reduce the potential danger of injuries caused during the deployment of the front air bags, the driver and front passenger must always be correctly seated and wear their seat belts.

For maximum protection in the event of a collision, you must always be in the normal seat position with your back against the backrest. Fasten your seat belt and make sure that it is correctly positioned on your body.

As the air bag inflates with considerable speed and force, a proper seating position and correct positioning of the hands on the steering wheel will help to keep you at a safe distance from the air bag. Occupants who are not wearing their seat belt, are not seated properly or are too close to the air bag can be seriously injured or killed by an air bag, as it inflates with great force instantaneously:

R sit with the seat belt fastened correctly and in a position that is as upright as possible with your back against the backrest.

R move the driver's seat as far back as possible, still permitting proper operation of vehicle controls. The distance from the center of the driver's chest to the center of the air bag cover on the steering wheel must be at least 10 inches (25 cm). You should be able to accomplish this by adjusting the seat and steering wheel. If you have any difficulties, please contact an authorized Mercedes-Benz Center.

R do not lean your head or chest close to the steering wheel or dashboard.

R only hold the steering wheel on the outside.

Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury if the driver front air bag inflates.

R adjust the front-passenger seat as far back as possible from the dashboard when the seat is occupied.

R occupants, especially children, should never place their bodies or lean their heads in the area of the door where the side impact air bag inflates. This could result in serious or fatal injuries should the side impact air bag be deployed. 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.

Failure to follow these instructions can result in severe injuries to you or other occupants.

Occupant safety

If you sell your vehicle, it is important that you make the buyer aware of this safety information. Be sure to give the buyer this

Operator's Manual.

G WARNING

Accident research shows that the safest place for children in an automobile is in a rear seat.

A side impact air bag related injury may occur if occupants, especially children, are not properly seated or restrained when next to a side impact air bag which needs to deploy rapidly in a side impact in order to do its job.

To help avoid the possibility of injury, please follow these guidelines:

(1) Always sit as upright as possible and use the seat belts properly.

Make sure that children 12 years old and under use an appropriately sized child restraint, infant restraint, or booster seat recommended for the size and weight of the child.

(2) Always wear seat belts properly.

needed to provide the best possible protection in a rollover.

Air bags provide additional protection; they are not, however, a substitute for seat belts.

All vehicle occupants must fasten their seat belts regardless of whether your vehicle is equipped with air bags or not.

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

Front air bags

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.

The air bags are deployed if the air bag control unit detects the need for deployment. Only in the event of such a situation will the air bags provide their supplemental protection.

If the driver and front passenger do not wear their seat belts, it is not possible for the air bags to provide their supplemental protection.

In the event of other types of impacts and impacts below air bag deployment thresholds, the air bags will not deploy. The driver and passengers will then be protected to the extent possible by a properly fastened seat belt. A properly fastened seat belt is also

Driver's air bag : deploys in front of the steering wheel; front-passenger front air bag ; deploys in front of and above the glove box.

The front air bags increase protection for the driver's and front-passenger's head and chest.

They are deployed:

R in the event of certain frontal impacts

R if the system determines that air bag deployment can offer additional protection to that provided by the seat belt

R depending on whether the seat belt is being used

R independently of other air bags in the vehicle

If the vehicle overturns, the front air bags are generally not deployed. If the system detects

Occupant safety

43 high vehicle deceleration in a longitudinal direction, the front air bags are deployed.

If a child restraint system is installed to the front-passenger seat and the 4

PASSENGER AIRBAG OFF indicator lamp does not light up on the center console:

R a child restraint system without transponders for air bag deactivation system is installed or

R a child restraint system with transponders is not properly installed.

Your vehicle has adaptive, two-stage front air bags. In the event of a collision, the air bag control unit evaluates the vehicle deceleration. In the first deployment stage, the front air bag is filled with enough propellant gas to reduce the risk of injuries.

The front air bag is fully deployed if a second deployment threshold is exceeded within a few milliseconds.

The deployment of the front-passenger front air bag is also influenced by the weight category of the front passenger, which is determined by the Occupant Classification

System (OCS) ( Y page 45).

The lighter the passenger side occupant, the higher the vehicle deceleration rate required

(predicted at the start of the impact) for second-stage inflation of the front-passenger front air bag. In the second stage, the front air bags are inflated with the maximum amount of propellant gas available.

The front air bags are not deployed in situations where a low impact severity is predicted. You will then be protected by the fastened seat belt.

Front-passenger front air bag will only deploy if:

R the system, based on the OCS weight sensor readings, has detected that the front-passenger seat is occupied.

R the 45 indicator lamp on the center console is not lit ( Y page 45).

R the air bag control unit predicts a high impact severity.

Knee bags

Driver's knee bag : deploys underneath the steering column and front-passenger knee bag ; underneath the glove box. They deploy together with the front air bags. They are designed to operate together with the front air bags in frontal impacts if certain thresholds are exceeded. The knee bags operate at best in conjunction with correctly positioned and fastened seat belts.

Knee bags provide increased protection for the driver and front passenger against the risk of:

R knee injuries

R thigh injuries

R lower leg injuries

Side impact air bags

G WARNING

Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using seat covers or other seat coverings can cause a malfunction of the side impact air bags and/or the pelvis air bags.

Contact an authorized Mercedes-Benz Center for availability.

G WARNING

The pressure sensors for side impact air bag control are located in the doors. Do not modify any components of the doors or door trim panels including, for example, the addition of door speakers.

Occupant safety

Improper repair work on the doors or the modification or addition of components to the doors create a risk of rendering the side impact air bags inoperative or causing unintended air bag deployment. Work on the doors must therefore only be performed by qualified technicians. Contact an authorized

Mercedes-Benz Center.

Front side impact air bags : and rear side impact air bags; deploy next to the outer seat cushions.

When deployed, the side impact air bags offer additional protection for the thorax of the vehicle occupants on the side of the vehicle on which the impact occurs. However, they do not protect the:

R head

R neck

R arms

The side impact air bags are deployed:

R on the side on which an impact occurs

R at the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact

R independently of the use of the seat belt

R independently of the front air bags

R independently of the ETDs

If the vehicle overturns, the side impact air bags are generally not deployed. side impact air bags are deployed if the system detects high vehicle deceleration or acceleration in a lateral direction and determines that side impact air bag deployment can offer additional protection to that provided by the seat belt.

Side impact air bags will not deploy in side impacts which do not exceed the system's preset deployment thresholds for lateral acceleration/deceleration. You will then be protected by the fastened seat belt.

The side impact air bag on the frontpassenger side is not deployed in the following situations:

OCS has detected that the front-passenger seat is unoccupied.

R the front-passenger seat belt is not fastened.

The side impact air bag on the frontpassenger side will deploy if the frontpassenger seat belt is fastened, regardless of whether the front-passenger seat is occupied or not.

Pelvis air bags

G WARNING

Contact an authorized Mercedes-Benz Center for availability.

Pelvis air bag deployment enhances the level of protection of the vehicle occupants on the side of the vehicle on which the impact occurs.

Occupant safety

Pelvis air bags : deploy next to and below the outer seat cushions. They are deployed:

R on the side on which an impact occurs

R at the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact

R independently of the use of the seat belt

R independently of the front air bags

R independently of the ETDs

If the vehicle overturns, the pelvis air bags are generally not deployed. Exception: if the system detects high vehicle deceleration or acceleration in a lateral direction and determines that deployment can offer additional protection to that provided by the seat belt.

Pelvis air bags : will not deploy in side impacts which do not exceed the system's preset deployment thresholds for lateral acceleration/deceleration. You will then be protected by the fastened seat belt.

The pelvis air bag on the front-passenger side is not deployed in the following situations:

R OCS has detected that the front-passenger seat is unoccupied.

R the front-passenger seat belt is not fastened.

The pelvis air bag on the front-passenger side will deploy if the front-passenger seat belt is fastened, regardless of whether the frontpassenger seat is occupied or not.

Window curtain air bags : enhance the level of protection for the head, but not chest or arms, of the vehicle occupants on the side of the vehicle on which the impact occurs.

window curtain air bags : enhance the level of protection for the head, but not chest or arms, of the vehicle occupants on the side of the vehicle on which the impact occurs.

The window curtain air bags are integrated into the side of the roof frame and deploy in the area from the A-pillar to the C-pillar.

Window curtain air bags are deployed:

R at the start of an accident with a high rate of lateral vehicle deceleration or acceleration, e.g. in a side impact

R on the side on which an impact occurs

R on the driver's and the front passenger's side if the vehicle overturns and the system determines that window curtain air bag deployment can offer additional protection to that provided by the seat belt

R independently of the use of the seat belt

R regardless of whether the front-passenger seat is occupied

R independently of the front air bags

Window curtain air bags will not deploy in impacts which do not exceed the system's preset deployment thresholds for lateral acceleration/deceleration. You will then be protected by the fastened seat belt.

Occupant Classification System

(OCS)

Method of operation

G WARNING

If the 45 indicator lamp illuminates when an adult or someone larger than a small individual is in the front-passenger seat, have the front passenger reposition himself or herself in the seat until the 45 indicator lamp goes out.

In the event of a collision, the air bag control unit will not allow front-passenger front air

Occupant safety bag deployment when the OCS has classified the front-passenger seat occupant as weighing as much as or less than a typical 12month-old child in a standard child restraint or if the front-passenger seat is classified as being empty.

When the OCS senses that the frontpassenger seat occupant is classified as being up to or less than the weight of a typical

12-month-old child in a standard child restraint, the 45 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the frontpassenger front air bag is deactivated.

When the OCS senses that the frontpassenger seat is classified as being empty, the 45 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the frontpassenger front air bag is deactivated.

When the OCS senses that the frontpassenger seat occupant is classified as being heavier than the weight of a typical 12month-old child seated in a standard child restraint or as being a small individual (such as a young teenager or a small adult), the

45 indicator lamp will illuminate for approximately 6 seconds when the engine is started and then, depending on occupant weight sensor readings from the frontpassenger seat, remain illuminated or go out.

With the 45 indicator lamp illuminated, the front-passenger front air bag is deactivated. With the 45 indicator lamp out, the front-passenger front air bag is activated.

When the OCS senses that the frontpassenger seat occupant is classified as an adult or someone larger than a small individual, the 45 indicator lamp will illuminate for approximately 6 seconds when the engine is started and then go out, indicating that the front-passenger front air bag is activated.

If the 45 indicator lamp is illuminated, the front-passenger front air bag and the front-passenger knee bag are deactivated and will not be deployed.

If the 45 indicator lamp is not illuminated, the front-passenger front air bag and the front-passenger knee bag are activated and will be deployed:

R in the event of certain frontal impacts

R if impact exceeds a preset deployment threshold

R independently of the side impact air bag or pelvis air bag

If the front-passenger front air bag is deployed, the rate of inflation will be influenced by:

R the rate of relevant vehicle deceleration as assessed by the air bag control unit

R the front passenger's weight category as identified by OCS

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 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 ISOFIX child seat retaining loops and Top Tether strap, fully in accordance with the infant or 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.

Occupant safety

Note the following important information if it is necessary to carry a child on the frontpassenger seat:

R Your vehicle is equipped with air bag technology designed to deactivate the front-passenger front air bag and the frontpassenger knee 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.

R 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 in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to eliminate this risk completely is never to place a child in a rear-facing child restraint in the frontpassenger seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint on the rear seat.

R If you install a rear-facing child restraint on the front-passenger seat, make sure the

45 indicator lamp is illuminated, indicating that the front-passenger front air bag and front-passenger knee bag are 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 that 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 could be seriously injured or even killed if the front-passenger front air bag is deployed.

R If you 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

secure child restraint with the vehicle's seat belt according to the child seat manufacturer's instructions

R For children larger than the typical 12month-old child, the front-passenger front air bag and the front-passenger knee bag may or may not be activated.

G WARNING

If the red 6 SRS warning lamp in the instrument cluster and the 45 indicator lamp light up simultaneously, the

OCS is malfunctioning. The front passenger front air bag and the front passenger knee bag will be deactivated in this case. Have the system checked by qualified technicians as soon as possible. Contact an authorized

Mercedes-Benz Center.

Only have the seat repaired or replaced at an authorized Mercedes-Benz Center.

In order to ensure proper operation of the air bag system and OCS:

R Sit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest.

R When seated, a passenger should not position him/herself in such a way as to cause the passenger's weight to be lifted from the seat cushion as this may result in the OCS being unable to correctly approximate the passenger's weight category.

R Read and observe all warnings in this chapter.

Occupant safety

If the SmartKey has been removed from the ignition lock or is in position 0, the

45 indicator lamp : does not light up.

The Occupant Classification System (OCS) categorizes the occupant on the frontpassenger seat by means of a weight sensor.

The front-passenger front air bag and the front-passenger knee bag are deactivated automatically for certain weight categories.

The 45 indicator lamp shows you the current status. If the 45 indicator lamp lights up, the front-passenger air bag and the front-passenger knee bag are disabled.

The system does not deactivate:

R the side impact air bag

R the pelvis air bag

R the window curtain air bag

R the Emergency Tensioning Devices

To be classified correctly, the front passenger must sit:

R with the seat belt fastened correctly

R in a position that is as upright as possible with their back against the seat backrest

R with their feet on the floor

The OCS weight sensor reading is affected if the occupant's weight is transferred, e.g. by leaning on the armrest.

If the front-passenger seat, the seat cover or the seat cushion are damaged, have the necessary repair work carried out at a qualified specialist workshop.

For safety reasons, Mercedes-Benz recommends that you only use seat accessories that have been approved by

Mercedes-Benz.

Both the driver and the front passenger should always observe the 45 indicator lamp to determine whether or not the front passenger is positioned correctly.

Also observe the air bag display messages, which appear in the instrument cluster

( Y page 235).

If the driver's air bag deploys, this does not mean that the front-passenger front air bag will also deploy.

The OCS may have detected that the seat:

R is empty or occupied by the weight of a typical child up to twelve months old, seated in a child restraint system

R is occupied by a small individual, such as a young teenager or a small adult

R is occupied by a child in a child restraint system whose weight is greater than that of a typical twelve month old child.

These are examples of when the OCS deactivates the front-passenger front air bag and front-passenger knee bag. Deactivation takes place although the collision fulfills the criteria for deploying the driver's air bag.

For further information, see "Air bag display messages" ( Y page 235).

System self-test

G WARNING

If the 4 5 indicator lamp does not illuminate, the system is not functioning. You must contact an authorized Mercedes-Benz

Center before seating any child on the front passenger seat.

G WARNING

Never place anything between seat cushion and child seat (e.g. a pillow), since it reduces the effectiveness of the OCS. The underside and rear side child restraint system must be placed entirely on the seat cushion and the

backrest of the front-passenger seat backrest.

If necessary, adjust the tilt of the passenger seat backrest.

An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protection for the child.

Follow the manufacturer's instructions for installation of child restraint systems.

The 45 indicator lamp lights up:

R if you turn the SmartKey in the ignition lock to position 1 or 2

R if you press the KEYLESS-GO Start/Stop button once or twice on vehicles with

KEYLESS-GO

R if an adult is seated properly on the frontpassenger seat and the OCS classifies the occupant as an adult

The 45 indicator lamp goes out after approximately six seconds.

If the seat is not occupied and the OCS detects that the front-passenger seat is empty, the 45 indicator lamp will continue to light up. The 45 frontpassenger front air bag warning lamp then stays lit continuously.

NECK-PRO head restraints/NECK-

PRO luxury head restraints

Important safety notes

G WARNING

Do not attach any objects (e.g. a coat hanger) to the NECK-PRO head restraints/NECK-PRO luxury head restraints. Otherwise, the NECK-

PRO head restraints/NECK-PRO luxury head restraints may not function properly and in the event of a rear-end collision may not offer the protection they are designed to provide.

G WARNING

Seat or head restraint covers can cause a malfunction when the NECK-PRO head restraints/NECK PRO luxury head restraints are activated or when the side impact air bags or pelvis air bags are deployed, or they can prevent this completely. The NECK-PRO head restraints/NECK PRO luxury head restraints or side impact air bags/pelvis air bags can therefore not provide the intended protection.

Do not use any seat or head restraint covers.

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.

G WARNING

For reasons of safety, have the NECK-PRO head restraints/NECK-PRO luxury head restraints checked at an authorized

Mercedes-Benz Center after a rear-end collision.

NECK-PRO head restraints/NECK-PRO luxury head restraints increase protection of the driver's and front-passenger's head and neck. In the event of a rear collision of a certain severity, the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats are moved forwards and upwards. This provides better head support.

If the NECK-PRO head restraints/NECK-PRO luxury head restraints have been triggered in an accident, reset the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats

( Y page 52). Otherwise, the additional protection will not be available in the event of another rear-end collision. NECK-PRO head restraints/NECK-PRO luxury head restraints that have been triggered are moved forwards and can no longer be adjusted.

PRE-SAFE

system

G WARNING

The PRE-SAFE ® system reduces the impact of an accident on vehicle occupants, as long as their seat belts have been fastened correctly.

Although your vehicle is equipped with a PRE-

SAFE ® system, the possibility of injury in the event of an accident cannot be ruled out. You should therefore always drive carefully and adapt your driving style to the prevailing road, weather and traffic conditions.

G WARNING

Make sure that nobody can become trapped as you adjust the seat.

! Make sure that there are no objects in the footwell or behind the seats when resetting the seats. There is a risk that the seats and/or the objects could be damaged.

PRE-SAFE ® takes preemptive measures to protect occupants in certain hazardous situations.

PRE-SAFE ® intervenes:

R if BAS intervenes, e.g. in emergency braking situations

R if, on vehicles with DISTRONIC PLUS, BAS

PLUS intervenes powerfully

R if, on vehicles with DISTRONIC PLUS, the radar sensor system detects an imminent danger of collision in certain situations

R in critical driving situations, e.g. when physical limits are exceeded and the vehicle understeers or oversteers severely

PRE-SAFE ® takes the following measures depending on the hazardous situation detected:

R the front seat belts are pre-tensioned.

R the front-passenger seat is adjusted if it is in an unfavorable position.

R vehicles with a multicontour seat or active multicontour seat: the air pressure in the

Occupant safety

53 side bolsters of the seat cushion and backrest is increased.

R if the vehicle skids, the sliding sunroof/ panorama roof with power tilt/sliding panel and the side windows are closed so that only a small gap remains.

If the hazardous situation passes without resulting in an accident, PRE-SAFE ® slackens the belt pretensioning. The air pressure in the side bolsters on the multicontour seat/active multicontour seat is reduced again. All settings made by PRE-SAFE ® can then be reversed.

If the seat belts are not released:

X Move the backrest or seat back slightly, but only when the vehicle is stationary.

The belt pretensioning is reduced and the locking mechanism is released.

More information about seat belt adjustment, a convenience function integrated into PRE-

SAFE ® , can be found under "Seat belt adjustment" ( Y page 56).

Seat belts

Important safety notes

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

Always have damaged seat belts or seat belts that have been subjected to a load in an accident replaced and the anchorages checked.

Only use seat belts that have been approved by Mercedes-Benz.

Never tamper with seat belts. This can result in the unintended deployment of the

Emergency Tensioning Devices or the failure to deploy when necessary.

Do not bleach or dye seat belts, as this may severely weaken them. In the event of a collision, they may be unable to provide adequate protection.

Have all work carried out only by qualified technicians. Consult a qualified specialist workshop.

Occupant safety

The use of seat belts and infant and child restraint systems is required by law in:

R all 50 states

R U.S. territories

R the District of Columbia

R all Canadian provinces

Even where this is not required by law, all vehicle occupants should correctly fasten their seat belts before starting the journey.

i See "Children in the vehicle"

( Y page 58) for further information on infants and children traveling in the vehicle as well as on child restraint systems.

Correct use of the seat belts

G WARNING

USE SEAT BELTS PROPERLY

Seat 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.

R Each 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).

R Never 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.

R Position 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.

R Never wear seat belts over rigid or breakable objects in or on your clothing, such as eyeglasses, pens, keys etc., as these might cause injuries.

R Make sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing.

R Never 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.

R Seat 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.

R Pregnant 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.

R Place the seat backrest in a position that is as upright as possible.

R Check your seat belt during travel to make sure it is properly positioned.

Occupant safety

R Never place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.

R When 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

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.

Adjust the seat and move the backrest to an almost vertical position ( Y page 96).

Pull the seat belt smoothly through belt sash guide :.

X Without twisting it, guide the shoulder section of the seat belt across the middle of your shoulder and the lap section across your pelvis.

Belt warning for the driver and front passenger

Regardless of whether the driver's and frontpassenger seat belts have already been fastened, the 7 seat belt warning lamp lights up for six seconds each time the engine is started. It then goes out if the driver and the front passenger have fastened their seat belts.

Occupant safety

If the driver's seat belt is not fastened when 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 after six seconds the driver or front passenger have not fastened their seat belts and the doors are closed, the 7 seat belt warning lamp lights up:

R until the driver's or front passenger's seat belt is fastened

R once the vehicle has exceeded a speed of

15 mph (25 km/h), in addition a warning tone will sound with increasing intensity for up to 60 seconds or until the driver's or front-passenger seat belt is fastened.

If the driver/front passenger unfasten their seat belt while the vehicle is in motion, the

7 seat belt warning lamp lights up and a warning tone sounds again.

The warning tone ceases after 60 seconds even if the driver or front passenger has still not fastened their seat belt. The 7 seat belt warning lamp stops flashing but remains illuminated.

After the vehicle comes to a standstill, the warning tone is reactivated and the 7 seat belt warning lamp flashes again if the vehicle speed again exceeds 15 mph (25 km/h).

The 7 seat belt warning lamp only goes out if:

R both the driver and the front passenger have fastened their seat belts.

R the vehicle is stationary and a door is open.

i For more information on the 7 seat belt warning lamp, see "Warning and indicator lamps in the instrument cluster, seat belts" ( Y page 256).

Emergency Tensioning Devices, belt force limiters

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 frontpassenger seat. Otherwise, the Emergency

Tensioning Device could be triggered in the event of an accident.

The seat belts are equipped with Emergency

Tensioning Devices and 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.

If the seat belt is also equipped with a seat belt force limiter and this is triggered, the force exerted by the seat belt on the vehicle occupant is reduced.

When triggered, seat belt force limiters help to reduce the peak force exerted by the seat belt on the vehicle occupant.

The belt force limiters for the front seats are synchronized with the front air bags, which take on a part of the deceleration force. This results in the force exerted on the occupant being distributed over a greater area.

The ETDs can only be activated when:

R the ignition is switched on.

R the restraint systems are operational; see

"SRS warning lamp" ( Y page 39).

Children in the vehicle

R the belt tongue is engaged in the buckle on each of the lap-shoulder belts in the front.

R the front-passenger seat is occupied and the belt tongue is engaged in the buckle on the front-passenger side.

The ETDs on the 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:

R if, 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

R if, in the event of a side impact, on the side opposite the impact the vehicle decelerates or accelerates rapidly in a lateral direction

R if, in certain situations where the vehicle overturns, the system determines that it can provide additional protection

If the ETDs 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.

Children in the vehicle

Child restraint systems

Important safety notes

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.

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:

R 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.

R 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 4 5 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated.

R 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 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.

R If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do

Children in the vehicle

59 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.

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.

R If you have to place a child in a forwardfacing 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. In the event of an accident, they could be crushed between the occupant and seat belt.

Children that are too large for a child restraint must travel in seats using normal 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.

G WARNING

When leaving the vehicle, always remove the

SmartKey from the ignition lock. 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:

R injure themselves on parts of the vehicle

R be seriously or fatally injured through excessive exposure to extreme heat or cold

R injure themselves or cause an accident with vehicle equipment that can be operated even if the SmartKey is removed from the ignition lock 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 compartment or trunk unless they are firmly secured in place.

Unsecured or improperly positioned cargo increases a child's risk of injury in the event of

R strong braking maneuvers

R sudden changes of direction

R an accident

Driving safety systems

Driving safety systems overview

In this section, you will find information about the following driving safety systems:

ABS ( Anti-lock Braking System)

( Y page 64)

BAS ( Brake Assist System) ( Y page 64)

R BAS PLUS ( Brake Assist System PLUS)

( Y page 65)

R ESP ® ( Electronic Stability Program)

( Y page 66)

EBD ( electronic brake force distribution)

( Y page 69)

R ADAPTIVE BRAKE( Y page 69)

R PRE-SAFE ® Brake ( Y page 69)

Important safety notes

If you fail to adapt your driving style or become distracted, the driving safety systems can neither reduce the risk of accident nor override the laws of physics.

Driving safety systems are merely aids designed to assist driving. You are

Driving safety systems responsible for the distance to the vehicle in front, for vehicle speed and for braking in good time. Always adapt your driving style to suit the prevailing road and weather conditions and maintain a safe distance from the vehicle in front. Drive carefully.

i The driving safety systems described only work as effectively as possible when there is adequate contact between the tires and the road surface. Please pay special attention to the notes on tires, recommended minimum tire tread depths, etc. ( Y page 326).

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 works from a speed of about 5 mph

(8 km/h) upwards, regardless of road-surface conditions. ABS works on slippery surfaces, even if you only brake gently.

The yellow ! ABS 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: continue to depress the brake pedal vigorously until the braking situation is over.

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

If ABS intervenes when braking, you will feel a pulsing in the brake pedal.

The pulsating brake pedal can be an indication of hazardous road conditions, and functions as a reminder to take extra care while driving.

ABS (Anti-lock Braking System)

Important safety notes

i Observe the "Important safety notes" section ( Y page 63).

G WARNING

If ABS is faulty, the wheels could lock when braking. The steerability and braking characteristics may be severely impaired.

Additionally, further driving safety systems are deactivated. There is an increased danger of skidding and accidents.

Drive on carefully. Have ABS checked immediately at a qualified specialist workshop.

When ABS is malfunctioning, other systems, including driving safety systems, will also become inoperative. Observe the information on the ABS warning lamp ( Y page 258) and display messages which may be shown in the instrument cluster ( Y page 229).

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.

BAS (Brake Assist System)

i Observe the "Important safety notes" section ( Y page 63).

G WARNING

If BAS is malfunctioning, the braking distance in an emergency braking situation is increased. There is a risk of an accident.

In an emergency braking situation, depress the brake pedal with full force. ABS prevents the wheels from locking.

BAS operates in emergency braking situations. If you depress the brake pedal quickly, BAS automatically boosts the braking force, thus shortening the stopping distance.

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

Driving safety systems

BAS PLUS (Brake Assist System Plus)

i Observe the "Important safety notes" section ( Y page 63).

BAS PLUS is only available in vehicles equipped with DISTRONIC PLUS.

BAS PLUS provides braking assistance in hazardous situations at speeds greater than

4 mph (7 km/h) and uses radar sensor technology to assess the traffic situation.

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.

BAS PLUS can also react to stationary obstacles, e.g. stopped or parked vehicles, at speeds of up to approximately 40 mph

(70 km/h).

To prevent a front-end collision, BAS PLUS calculates the brake force necessary if:

R you approach an obstacle, and

BAS PLUS has detected a risk of collision

For speeds above 20 mph (30 km/h): if you apply the brakes forcefully, BAS PLUS automatically increases the braking force to a level suitable for the traffic conditions.

For speeds below 20 mph (30 km/h): if 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.

BAS PLUS is deactivated and the brakes function as usual, if:

R you release the brake pedal.

R there is no longer any danger of a rear-end collision.

R no obstacle is detected in front of your vehicle.

For BAS PLUS to assist you when driving, the radar sensor system must be:

R switched on ( Y page 223)

Important safety notes

i Observe the "Important safety notes" section ( Y page 63).

G WARNING

If ESP ® is malfunctioning, ESP ® is unable to stabilize the vehicle. Additionally, further driving safety systems are deactivated. This increases the risk of skidding and an accident.

Drive on carefully. Have ESP ® qualified specialist workshop.

checked at a

! 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.

Vehicles without 4MATIC: when towing your vehicle with the rear axle raised, it is important that you observe the notes on

ESP ® ( Y page 320).

ESP ® is deactivated if the å warning lamp in the instrument cluster lights up continuously when the engine is running.

If the ÷ warning lamp and the å warning lamp are lit continuously, ESP ® is not available due to a malfunction.

Observe the information on warning lamps

( Y page 260) and display messages which may be shown in the instrument cluster

( Y page 229).

If ESP ® detects that the vehicle is deviating from the direction desired by the driver, one or more wheels are braked to stabilize the vehicle. The engine output is also modified to keep the vehicle on the desired course within physical limits. ESP ® assists the driver when pulling away on wet or slippery roads. ESP ® can also stabilize the vehicle during braking.

If ESP ® intervenes, the ÷ ESP ® warning lamp flashes in the instrument cluster.

If ESP ® intervenes:

Do not deactivate ESP ® under any circumstances.

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

Adapt your driving style to suit the prevailing road and weather conditions.

i Only use wheels with the recommended tire sizes. Only then will ESP ® function properly.

ETS/4ETS (Electronic Traction System)

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 ® .

EBD (electronic brake force distribution)

i Observe the "Important safety notes" section ( Y page 63).

G WARNING

If EBD has malfunctioned, the rear wheels can still lock, e.g. under full braking. This increases the risk of skidding and an accident.

You should therefore adapt your driving style to the different handling characteristics. Have the brake system checked at a qualified specialist workshop.

Observe information regarding indicator and warning lamps ( Y page 258) as well as display messages ( Y page 231).

EBD monitors and controls the brake pressure on the rear wheels to improve driving stability while braking.

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 178) and hill start assist

( Y page 142).

PRE-SAFE

Brake

i Observe the "Important safety notes" section ( Y page 63).

PRE-SAFE ® Brake is only available in vehicles with DISTRONIC PLUS.

PRE-SAFE ® Brake can help you to minimize the risk of a collision with a vehicle ahead or reduce the effects of such a collision. If PRE-

SAFE ® Brake detects 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.

Above a speed of around 4 mph (7 km/h), this function warns you if you are very quickly approaching a vehicle in front. An intermittent warning tone will then sound and the · distance warning lamp will light up in the instrument cluster.

X or

Brake immediately in order to increase the distance from the vehicle in front.

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.

Driving safety systems

You can prevent the intervention of the PRE-

SAFE ® Brake at any time by:

R depressing the accelerator pedal further

R activating kickdown

R releasing the brake pedal.

The braking action of PRE-SAFE ® Brake is ended automatically if:

R you maneuver to avoid the obstacle.

R there is no longer any danger of a rear-end collision.

R there is no longer an obstacle detected in front of your vehicle.

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 of up to 40 mph (70 km/h), PRE-

SAFE ® Brake can also detect stationary obstacles, for example, stopped or parked vehicles.

If you approach an obstacle and PRE-SAFE ®

Brake detects a risk of a collision, the system will 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, preventive passenger protection measures (PRE-SAFE ® ) are activated

( Y page 52). If, at speeds over 20 mph

(30 km/h), a risk of collision remains and you do not brake, take evasive action or significantly accelerate, automatic braking may be performed up to the level of emergency braking. Automatic emergency braking is not performed until immediately prior to an accident that can no longer be avoided.

G WARNING

PRE-SAFE ® Brake will initially brake your vehicle by a partial application of the brakes if a danger of collision is detected. There may be a collision unless you also brake.

Automatic emergency braking cannot prevent a collision. There is a risk of an accident.

Always apply the brakes yourself and try to take evasive action.

G WARNING

PRE-SAFE ® Brake cannot always clearly identify objects and complex traffic conditions.

In these cases, PRE-SAFE ® Brake may:

R give an unnecessary warning and then brake the vehicle

R not give a warning or intervene

There is a risk of an accident.

Always pay particular attention to the traffic situation and be ready to brake, especially if

PRE-SAFE ® Brake warns you. Terminate the intervention in a non-critical driving situation.

In particular, the detection of obstacles can be impaired if there is:

R dirt on the sensors or anything else covering the sensors

R snow or heavy rain

R interference by other radar sources

R the possibility of strong radar reflections, for example in parking garages

R a narrow vehicle traveling in front, e.g. a motorbike

R a vehicle traveling in front on a different line relative to the center of your vehicle

G WARNING

PRE-SAFE ® Brake does not react:

R to people or animals

R to oncoming vehicles

R to crossing traffic

R when cornering

As a result, PRE-SAFE ® Brake may neither give warnings nor intervene in all critical situations. There is a risk of an accident.

Always pay careful attention to the traffic situation and be ready to brake.

Theft deterrent locking system

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

X To activate/deactivate: activate or deactivate PRE-SAFE ® Brake in the onboard computer ( Y page 218).
