Operating safety

Warning!
G
Work improperly carried out on electronic components and associated software could cause them to cease functioning. Because the vehicle’s electronic components are interconnected, any modifications made may produce an undesired effect on other systems. Electronic malfunctions could seriously impair the operating safety of your vehicle.
Contact an authorized Mercedes-Benz Center for repairs or modifications to electronic components.
Other improper work or modifications on the vehicle could also have a negative impact on the operating safety of the vehicle.
Some safety systems only function while the engine is running. You should therefore never turn off the engine while driving.
Warning!
G
Heavy blows against the vehicle underbody or tires/wheels may cause serious damage and impair the operating safety of your vehicle. Such blows can be caused, for example, by running over an obstacle, road debris or a pothole. If you feel a sudden significant vibration or ride disturbance, or you suspect that damage to your vehicle as occurred:
turn on your hazard warning flashers
slow down carefully
drive with caution to an area which is a safe distance from the road
Inspect the vehicle underbody and tires/ wheels for possible damage. If the vehicle appears unsafe, have it towed to the nearest authorized Mercedes-Benz Center or other qualified maintenance or repair facility for further inspection or repairs.

Occupant safety

Introduction

In this section you will learn the most important facts about the restraint system

Safety and security

components of the vehicle.
The restraint systems are:
Seat belts
Child restraints
Lower Anchors and Tethers for CHildren (LATCH) also known as ISOFIX
Additional protection potential is provided by:
Supplemental Restraint System (SRS) with
-
Air bags
-
Air bag control unit (with crash sensors)
-
Emergency Tensioning Device (ETD) for seat belts
-
Seat belt force limiter
NECK-PRO active front head restraints
Preventive occupant safety (PRE-SAFE®)
Air bag system components with
-
Front passenger front air bag off indicator lamp
-
Front passenger seat with Occupant Classification System (OCS)
Although the systems are independent, their protective functions work in conjunction with each other.
Warning!
G
Modifications to or work improperly conducted on restraint system components or their wiring, as well as tampering with interconnected electronic systems, can lead to the restraint systems no longer functioning as intended.
Air bags or Emergency Tensioning Devices (ETDs), for example, could deploy inadvertently or fail to deploy in accidents although the deceleration threshold for air bag deployment is exceeded. Therefore, never modify the restraint systems. Do not tamper with electronic components or their software.
i
See “Children in the vehicle”
(Y page 53) for information on
infants and children traveling with you in the vehicle
restraint systems for infants and children

SRS indicator lamp

The SRS system conducts a self-test when the ignition is switched on and in regular intervals while the engine is running. This facilitates detection of system malfunctions.
The SRS indicator lamp 6 in the instrument cluster comes on when the ignition is switched on. It goes out no later than a few seconds after the engine has been started.
The SRS components are in operational readiness when the SRS indicator lamp 6 is not lit while the engine is running.
Occupant safety
37
Warning!
G
The SRS self-check has detected a malfunction when the SRS indicator lamp
6
does not come on at all
fails to go out after approximately 4 seconds after the engine was started
comes on after the engine was started or while driving
For your safety, we strongly recommend that you contact an authorized Mercedes-Benz Center immediately to have the system checked. Otherwise the SRS may not be activated when needed in an accident, which could result in serious or fatal injury. The SRS might also deploy unexpectedly and unnecessarily which could also result in injury as well.
In addition, improper 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.
If it is necessary to modify an air bag system to accommodate a person with disabilities, contact an authorized Mercedes-Benz Center. USA only: Call our Customer Assistance Center at 1-800-FOR-MERCedes (1-800-367-6372) for details.

Air bags

Warning!
G
Air bags are designed to reduce the potential of injury and fatality in certain
frontal impacts (front air bags and driver’s side knee bag)
side impacts (side impact air bags, window curtain air bags and pelvis air bags)
However, no system available today can completely eliminate injuries and fatalities.
Deployment of the air bags temporarily releases a small amount of dust from the air bags. This dust, however, is neither harmful to your health, nor does it indicate a fire in the vehicle. The dust might cause some temporary breathing difficulty for people with asthma or other breathing trouble. To avoid this, you may wish to get out of 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.
Warning!
G
To reduce the risk of injury when the front air bags inflate, it is very important for the driver and front passenger to always be in a properly seated position and to wear their respective seat belt.
For maximum protection in the event of a collision always be in normal seated position with your back against the seat backrest. Fasten your seat belt and make sure it is properly positioned on your body.
Since 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:
Sit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest.
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) or more. You should be able to accomplish this by adjusting the seat and steering wheel. If
Safety and security
Z
Occupant safety
38
you have any difficulties, please contact an authorized Mercedes-Benz Center.
Do not lean your head or chest close to the steering wheel or dashboard.
Keep hands on the outside of the steering wheel rim. Placing hands and arms inside the rim can increase the risk and potential severity of hand/arm injury when the driver front air bag inflates.
Adjust the front passenger seat as far as possible rearward from the dashboard when the seat is occupied.
Occupants, especially children, should
Safety and security
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 injuries or death 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.
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.
Warning!
G
Accident research shows that the safest place for children in an automobile is in a rear seat.
There is a possibility for a side impact air bag­related injury 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,
wear the seat belt properly, and for children 12 years old and under,
use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child.
(2) Always wear seat belts properly.
Air bags are designed to deploy only in certain
frontal impacts (front air bags and driver’s side knee bag)
side impacts (side impact air bags, pelvis air bags and window curtain air bags) if the system determines the need for air bag deployment
Only in the event of such a situation will they provide their supplemental protection.
The driver and passengers should always wear their seat belts. Otherwise it is not possible for the air bags to provide their supplemental protection.
In case of other types of impacts and impacts below air bag deployment thresholds, 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 needed to provide the best possible protection in a rollover.
Air bags are not a substitute for seat belts. Always wear your seat belt, regardless of whether or not your vehicle is equipped with air bags.
It is important to 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 will continue to provide supplemental crash protection for occupants.
Safety guidelines for the seat belt, Emergency Tensioning Device (ETD) and air bag
Warning!
G
Damaged seat belts or seat belts that have been subjected to stress in an accident
Occupant safety

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 with your local government’s 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. PRE­SAFE® has electrically operated reversible pre-tensioners in addition to the pyrotechnic ETDs.
Do not pass seat belts over sharp edges. They could tear.
Do not make any modification that could change the effectiveness of the seat belts.
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.
No modifications of any kind may be made to any components or wiring of the SRS.
Do no change or remove any component or part of the SRS.
Do not install additional trim material, seat covers, badges, etc. over the steering wheel hub, front passenger front air bag cover, outboard sides of the seat backrests, door trim panels, or door frame trims.
Do not install additional electrical/ electronic equipment on or near SRS components and wiring.
Keep area between air bags and occupants free of objects (e.g. packages, purses, umbrellas, etc.).
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.
Air bag system components will be hot after an air bag has inflated. Do not touch them.
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.
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.
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.
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, we strongly recommend 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.

Front air bags
Observe Safety notes, see page 37.
G
Driver’s front air bag : and front passenger
Safety and security
front air bag ; are designed to provide increased protection for the driver and front passenger against the risk of injuries to the head and thorax.
Driver and front passenger front air bag and driver’s side knee bag are deployed
in the event of certain frontal impacts
if the system determines that air bag deployment can offer additional protection to that provided by the seat belt
depending on whether the respective seat belt is in use
independently of the side impact air bags, pelvis air bags and/or the window curtain air bags
The front air bags in this vehicle have been designed to inflate in two stages. This allows the air bags to have different rates of inflation. The rate of inflation is based on the vehicle deceleration rate as assessed by the air bag control unit.
The front passenger front air bag deployment is additionally influenced by the passenger’s weight category as identified by the Occupant Classification System (OCS) (Y page 42).
The lighter the front passenger-side occupant, the higher the vehicle deceleration rate required for second stage inflation of the front passenger front air bag.
The air bags will not deploy in impacts which do not exceed the system’s preset deployment thresholds. You will then be protected by the fastened seat belts.
The front air bags will not deploy in the event of a rollover unless the vehicle’s rate of longitudinal deceleration or acceleration exceeds the preset deployment threshold for the front air bags.
The front passenger front air bag will only be deployed if
the system, based on OCS weight sensor readings, detects that the front passenger seat is occupied
the 45 indicator lamp in the center console is not lit (Y page 42)
the impact exceeds a preset deployment threshold
Knee bag
Knee bag = is designed to provide increased protection for the driver against the risk of injuries to the knees, thighs and lower legs.
Knee bag = is located on the driver side lower instrument panel. It is designed to operate together with the driver front air bag in certain frontal impacts if the system determines that air bag deployment can offer additional protection to that provided by the seat belt. Knee bag = operates best in conjunction with a properly positioned and fastened seat belt.
Side impact air bags
Observe Safety notes, see page 37.
G
Warning!
G
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.
Improper repair work on the doors or the modification or addition of components to the
Occupant safety
41
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.
Side impact air bags : are designed to provide increased protection for the thorax but not the head, neck and arms of the driver or front passenger.

The front passenger side impact air bag will not deploy if the OCS senses that the front passenger seat is empty and the front passenger seat belt is not fastened. With the front passenger seat empty and the seat belt fastened, the front passenger side impact air bag will deploy independently of the empty seat. Whether a seat belt is recognized as fastened depends on whether or not the latch plate is properly inserted into the buckle.
Side impact air bags : are not deployed in side impacts which do not exceed the system’s deployment threshold.
Side impact air bags : will not deploy in the event of a rollover unless the vehicle’s rate of lateral deceleration or acceleration exceeds the preset deployment threshold for side impact air bags :.
Warning!
G
Only use seat covers which have been tested and approved by Mercedes-Benz for your vehicle model. Using other seat covers may interfere with or prevent the deployment of the side impact air bags and/or pelvis air bags. Contact an authorized Mercedes-Benz Center for availability.

Window curtain air bags : are not deployed in impacts which do not exceed the system’s deployment threshold.
Window curtain air bags : deploy in the area indicated by the arrows.

Occupant Classification System

The Occupant Classification System (OCS) activates or deactivates the front passenger front air bag automatically. The respective status is based on the classified occupant weight category determined by weight sensor readings from the front passenger seat.
The system does not deactivate
the front passenger side impact air bag
the pelvis air bag
the window curtain air bag
the Emergency Tensioning Devices (ETDs)
To be classified correctly, the front passenger must sit
with the seat belt properly fastened
in a position that is as upright as possible with the back against the seat backrest
with the feet on the floor
If the occupant’s weight is transferred to another object in the vehicle (e.g. by leaning on armrests), the OCS may not be able to properly approximate the occupant’s weight category.
If your seat, including the trim cover and cushion, needs to be serviced in any way, take the vehicle to an authorized Mercedes-Benz Center.
Only seat accessories approved by Mercedes-Benz may be used.
Both the driver and the front passenger should always use the 45 indicator
Occupant safety
43
lamp as an indication of whether or not the front passenger is properly positioned.
Warning!
G
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 bag deployment when the OCS has classified the front passenger seat occupant as weighting as much as or less than a typical 12-month­old child in a standard child restraint or if the front passenger seat is classified as being empty.
When the OCS senses that the front passenger 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 front passenger front air bag is deactivated.
When the OCS senses that the front passenger seat is classified as being empty, the 45 indicator lamp will illuminate when the engine is started and remain illuminated, indicating that the front passenger front air bag is deactivated.
When the OCS senses that the front passenger seat occupant is classified as being heavier than the weight of a typical 12-month-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 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 front passenger 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 goes out, indicating that the front passenger front air bag is activated.
If the 45 indicator lamp is illuminated, the front passenger front air bag is deactivated and will not be deployed.
If the 45 indicator lamp is not illuminated, the front passenger front air bag is activated and will be deployed
in the event of certain frontal impacts
if impact exceeds a preset deployment threshold
independently of the side impact air bags or pelvis air bag
If the front passenger front air bag is deployed, the rate of inflation will be influenced by
the rate of relevant vehicle deceleration as assessed by the air bag control unit
the front passenger’s weight category as identified by the OCS
For more information on air bag display messages in the multifunction display, see (Y page 235).
Warning!
G
According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster

seat recommended for the size and weight of the child.
The infant or child restraint must be properly secured with the vehicle’s seat belt, the seat belt and top tether strap, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions.
Occupants, especially children, should always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child.
Children can be killed or seriously injured by
Safety and security
an inflating air bag. Note the following important information when circumstances require you to place a child in the front passenger seat:
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.
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.
If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 45 indicator lamp not illuminate or go out while the restraint is
installed, please check installation. Periodically check the 45 indicator lamp while driving to make sure the 45 indicator lamp is illuminated. If the 45 indicator lamp goes out or remains out, do not transport a child on the front passenger seat until the system has been repaired.
A child in a rear-facing child restraint on the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates.
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. For children larger than the typical 12-month­old child, the front passenger front air bag may or may not be activated.
Deployment of the driver front air bag does not mean that the front passenger front air bag also should have deployed.
The OCS may have determined
that the seat was empty or occupied by the weight up to or less than that of a typical 12-month-old child seated in a standard child restraint – both of which are instances where the system suppresses deployment of the front passenger front air bag even though the impact met the criteria and was of sufficient severity to deploy the driver front air bag
that the seat was occupied by a small individual (such as a young teenager or a small adult) or a child who weighs more than the weight of a typical 12-month-old child in a standard child restraint – both of which are instances where the system may suppress deployment of the front passenger front air bag even though the impact met the criteria and was of

45 indicator lamp : will be illuminated, except with the SmartKey removed from the starter switch or with the starter switch in position 0.
Warning!
G
If the red SRS indicator lamp 6 in the instrument cluster and the 45 indicator lamp are lit at the same time, there is a malfunction in the OCS. The front passenger front air 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:
Sit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest.
While seated, an occupant should not position him/herself in such a way as to cause the occupant’s weight to be lifted from the seat bottom as this may result in the OCS being unable to correctly approximate the occupant’s weight category.
Read and observe all warnings in this chapter.
OCS Self-test
After turning the SmartKey in the starter switch to position 1 or 2 or pressing the KEYLESS-GO start/stop button once or twice, the 45 indicator lamp illuminates. If an adult occupant is properly sitting on the front passenger seat and the system classifies the occupant as an adult, the 45 indicator lamp will illuminate and go out after approximately 6 seconds.
If the seat is not occupied and the system classifies the front passenger seat as being empty, the 45 indicator lamp will illuminate and not go out.
Warning!
G
If the 45 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.
For more information, see the “Practical hints” section (Y page 270).
Warning!
G
Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the OCS. The bottom and back of the child seat must make full contact with the passenger seat cushion and 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 seats.

Warning!
G
Always fasten your seat belt before driving off. Always make sure all of your passengers are
Safety and security
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.
Warning!
G
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.
Warning!
G
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.
Warning!
G
Damaged seat belts or seat belts that have been subjected to stress in an accident must be replaced. Also, the seat belt anchoring points must be checked.
Only use seat belts which have been approved by Mercedes-Benz.
Do not make any modifications to the seat belts. This can lead to unintended activation of the ETDs or to their failure to activate when necessary.
Do not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection.
Have all work carried out only by qualified technicians. Contact an authorized Mercedes-Benz Center.
Proper use of seat belts
Warning!
G
USE SEAT BELTS PROPERLY
Seat belts can only protect when used properly. Never wear seat belts in any other way than as described in this section, as that could result in serious injuries in case of an accident.
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 side knee bag, front passenger front air bag, side impact air bags, pelvis air bags, window curtain air bags for side windows), Emergency Tensioning Devices (ETDs),
Occupant safety
47
seat belt force limiters, and front seat knee bolsters.
The system is designed to enhance the protection offered to properly belted occupants in certain frontal (front air bags, driver’s side knee bag, and ETDs) and side (side impact air bags, pelvis air bags, window curtain air bags, and ETDs) impacts which exceed preset deployment thresholds.
Never wear the shoulder belt under your arm, against your neck or off your shoulder. In a frontal crash, your body would move too far forward. That would increase the chance of head and neck injuries. The seat belt would also apply too much force to the ribs or abdomen, which could severely injure internal organs such as your liver or spleen.
Adjust the seat belt so that the shoulder section is located as close as possible to the middle of the shoulder. It should not touch the neck. Never pass the shoulder portion of the seat belt under your arm.
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.
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.
Make sure the seat belt is always fitted snugly. Take special care of this when wearing loose clothing.
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.
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.
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.
Place the seat backrest in a position that is as upright as possible.
Check your seat belt during travel to make sure it is properly positioned.
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.
When using a seat belt to secure infant restraints, toddler restraints, or children in booster seats, always follow the child seat manufacturer’s instructions.
Warning!
G
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 the seat belts
Warning!
G
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 appropriately sized infant restraint, toddler restraint, or booster seat recommended for

Damaged seat belts must be replaced. Contact an authorized Mercedes-Benz Center.
Enhanced seat belt reminder system
When the engine is started, the seat belt telltale 7 will always illuminate for 6 seconds to remind you and your passengers to fasten your seat belts.
If the driver’s seat belt is not fastened when the engine is started, an additional warning chime will sound. The warning chime goes out after approximately 6 seconds or once the driver’s seat belt is fastened.
If after these 6 seconds the driver’s or the front passenger’s seat belt (with the front passenger seat occupied) is not fastened with both doors closed,
the seat belt telltale 7 remains illuminated for as long as either the driver’s or front passenger’s seat belt is not fastened.
and if the vehicle speed once exceeds 15 mph (25 km/h), the seat belt telltale 7 starts flashing and a warning chime sounds with increasing intensity for a maximum of 60 seconds or until the driver’s and front passenger’s seat belt are fastened.
If you and/or your passenger release the seat belt during driving, the seat belt telltale 7 starts flashing and the warning chime sounds as described before.
If the driver’s or the front passenger’s seat belt remains unfastened after 60 seconds, the warning chime stops sounding, the seat belt telltale 7 stops flashing but continues to be illuminated.

Emergency Tensioning Device (ETD), seat belt force limiter
Safety and security
The seat belts are equipped with ETDs and seat belt force limiters.
The ETDs are designed to activate in the following cases:
in frontal or rear-end impacts exceeding the system’s preset deployment threshold
in side impacts exceeding the system’s preset deployment threshold on the far side of the impact
if the restraint systems are operational and functioning correctly, see “SRS indicator lamp” (Y page 36)
The ETDs for the front seats will only activate if the front seat belts are fastened (latch plate properly inserted into buckle).
The ETDs for the rear seats will activate with or without the respective seat belts fastened.
In an impact, the ETDs remove slack from the seat belts in such a way that the seat belts fit more snugly against the body. Seat belt force limiters, when activated, are employed to help reduce the peak force exerted by the seat belts on occupants during a crash.
i
The ETDs do not correct an incorrect seat
position or incorrectly worn seat belts.
The ETDs do not pull occupants back toward the seat backrest.
Warning!
G
Pyrotechnic ETDs that were activated must be replaced.
For your safety, when disposing of the pyrotechnic ETDs always follow our safety instructions. These are available at any authorized Mercedes-Benz Center.
The PRE-SAFE® system has electrically operated reversible pre-tensioners that do not require replacement after activation.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for the front seats reduces the retracting force of the seat belts when they are in normal use.
Preventive occupant safety (PRE­SAFE®)
Warning!
G
The PRE-SAFE® system is intended to reduce the effects of an accident on vehicle occupants who are wearing their seat belt properly. Despite your vehicle being equipped with the PRE-SAFE® system, the possibility of personal injuries occurring as a result of an accident cannot be eliminated. Therefore, always drive carefully and adjust your driving to the prevailing road, weather, and traffic conditions.
The PRE-SAFE® system takes preventive measures to better protect the occupants from the possibility of personal injuries in the following hazardous situations:
emergency braking situations, e.g. if the Brake Assist System (BAS) (Y page 60) is activated
or when
vehicles with DISTRONIC PLUS:
Occupant safety
51
the BAS PLUS (Y page 60) or the PRE­SAFE® Brake (Y page 63) is strongly engaging
when the radar sensors recognize the immediate risk of collision in certain situations (vehicles with DISTRONIC PLUS)
critical dynamic driving situations, e.g. when the vehicle has been caused to understeer or oversteer because it has exceeded its physical limitations or in case of evasive steering maneuvers at speeds above approximately 85 mph (140 km/h)
The PRE-SAFE® system takes the following measures when it is activated:
The front seat belts are pre-tensioned automatically.
If the front passenger seat is in an unfavorable position, the seat will be adjusted to a position that seeks to better protect the occupant.
The system increases the air pressure in the air pockets (on the sides of the seat cushion and backrest) of the multicontour front seats.
If the vehicle is in a critical dynamic driving situation, the door windows and the panorama roof with tilt/sliding panel also closes, except for a minimal gap that remains open.
If the closing procedure of any of these elements is blocked, it will stop and open slightly.
Once the hazardous situation no longer exists and an accident has been avoided, the PRE­SAFE® system loosens the seat belt pre­tension and decreases the air pressure in the air pockets of the multicontour front seats. All of the PRE-SAFE® system settings can be re-adjusted following the critical driving event.
If the seat belts do not release:
X
Adjust the seat backrest or seat slightly to the rear until the seat belt tension is reduced. The locking mechanism releases.
!
When moving the seats, make sure there are no items in the footwell or behind the seats. Otherwise, you could damage the seats and/or the items.
For information on the seat belt adjustment function as an integrated comfort feature of the PRE-SAFE® system, see (Y page 49).

NECK-PRO active front head restraints

The NECK-PRO active front head restraints are intended to offer the driver and front passenger increased protection from whiplash-type injuries. In the event of a rear­end collision, the NECK-PRO active front head restraints are designed to move forward and up in the direction of travel. They thus provide the head with increased support earlier on in the collision sequence. The NECK-PRO active front head restraints will move forward and up whether the seats are occupied or not.
Warning!
G
Do not attach any objects (e.g. hangers) to the head restraint posts. Otherwise, the NECK­PRO active front head restraints may not be able to function properly or offer the intended degree of protection they were designed for in the event of a rear-end collision.
Warning!
G
Only use seat or head restraint covers which have been tested and approved by Mercedes­Benz for your vehicle model.

For information on LATCH-type (ISOFIX) child seat anchors (Y page 57).
The use of infant or child restraints is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces.
Infants and small children should be seated in an appropriate infant or child restraint system. They must be properly secured in accordance with the manufacturer’s instructions for the child restraint. All infant or child restraint systems must comply with U.S. Federal Motor Vehicle Safety Standards 213 and 225 and Canadian Motor Vehicle Safety Standards 213 and 210.2.
A statement by the child restraint manufacturer of compliance with these standards can be found on the instruction label on the restraint and in the instruction manual provided with the restraint.
When using any infant restraint, toddler restraint, or booster seat, make sure to carefully read and follow all manufacturer’s instructions for installation and use.
Please read and observe warning labels affixed to the inside of the vehicle and to infant or child restraints.
Warning!
G
According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position.

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:
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.
For children larger than the typical 12-month-old child, the front passenger front air bag may or may not be activated. Always make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated.
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.
If you must install a rear-facing child restraint on the front passenger seat because circumstances require you to do so, make sure the 45 indicator lamp is illuminated, indicating that the front passenger front air bag is deactivated. Should the 45 indicator lamp not illuminate or go out while the restraint is installed, please check installation. Periodically check the 45 indicator lamp while driving to make sure the 45 indicator lamp is illuminated. If the 45 indicator lamp goes out or remains out, do not transport a child on the
front passenger seat until the system has been repaired.
A child in a rear-facing child restraint on the front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates.
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.
Warning!
G
Infants and small children should never share a seat belt with another occupant. During an accident, they could be crushed between the occupant and seat belt.
A child’s risk of serious or fatal injuries is significantly increased if the child restraints are not properly secured in the vehicle and/ or the child is not properly secured in the child restraint.
Children too big for a toddler restraint must ride in seats using regular seat belts. Position shoulder belt across chest and shoulder, not face or neck. A booster seat may be necessary to achieve proper seat belt positioning for children over 41 lb (18 kg) until they reach a height where a lap/shoulder belt fits properly without a booster.
When the child restraint is not in use, remove it from the vehicle or secure it with the seat belt to prevent the child restraint from becoming a projectile in the event of an accident.

Safety notes
Warning!
G
The following factors increase the risk of accidents:
Excessive speed, especially in turns
Wet and slippery road surfaces
Following 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.
lock during braking. This allows you to maintain the ability to steer your vehicle.
The ABS is functional above a speed of approximately 5 mph (8 km/h) independent of road surface conditions.
On slippery road surfaces, the ABS will respond even to light brake pressure.
The ABS indicator lamp ! in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.
Braking
At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal. The pulsation indicates that the ABS is in the regulating mode.
X
Keep firm and steady pressure on the brake pedal while you feel the pulsation.
Continuous, steady brake pedal pressure yields the advantages provided by the ABS, namely braking power and the ability to steer the vehicle.
The pulsating brake pedal can be an indication of hazardous road conditions and functions as a reminder to take extra care while driving.
Emergency brake maneuver
X
Keep continuous full pressure on the brake pedal.
Safety and security
ABS
Observe Safety notes, see page 59.
G
Warning!
G
Do not pump the brake pedal. Use firm, steady brake pedal pressure instead. Pumping the brake pedal defeats the purpose of the ABS and significantly reduces braking effectiveness.
The Antilock Brake System (ABS) regulates the brake pressure so that the wheels do not
Warning!
G
If the ABS malfunctions, other driving safety systems such as the BAS or the ESC are also switched off. Observe indicator and warning lamps that may come on as well as messages in the multifunction display that may appear.
If the ABS malfunctions, the wheels may lock during hard braking, reducing steering capability and extending the braking distance.

BAS
Observe Safety notes, see page 59.
G
The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS provides full brake boost automatically, thereby potentially reducing the braking distance.
X
Apply continuous full braking pressure until the emergency braking situation is over. The ABS will prevent the wheels from locking.
When you release the brake pedal, the brakes function again as normal. The BAS is then
Safety and security
deactivated.
Warning!
G
If the BAS malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase.

BAS PLUS

The Brake Assist System PLUS (BAS PLUS) operates in emergency braking situations and uses radar sensors to assess the traffic situation. BAS PLUS assists you in braking at speeds above approximately 20 mph (30 km/h).
When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 126). Canadian law does not permit the use of the radar sensor system for vehicles from outside of Canada.
When you switch off the radar system, the following functions are deactivated:
BAS PLUS
PRE-SAFE® Brake (Y page 63)
DISTRONIC PLUS (Y page 130)
Warning!
G
BAS PLUS is a convenience system designed to assist the driver during vehicle operation. The responsibility for the vehicle speed and the distance to the vehicle ahead, including most importantly brake operation to assure safe stopping distance, always remains with the driver.
Always pay attention to traffic conditions even while BAS PLUS is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late and could cause an accident. Personal or fatal injury to you or others may be the result.
i
This device has been approved by the FCC as a “Vehicular Radar System”. The radar sensor is intended for use in an automotive radar system only. Removal, tampering, or altering of the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way.
Any unauthorized modification to this device could void the user’s authority to operate the equipment.
BAS PLUS detects obstacles that are in your driving path for a sufficient period of time to permit the system to recognize these obstacles. If you approach the detected obstacle quickly, BAS PLUS calculates the level of brake power boost appropriate for the circumstance to supply when the driver applies the brakes.
When you step quickly on the brake pedal in an emergency braking situation, BAS PLUS automatically regulates the brake power boost to a level that is suitable for the traffic situation.
If BAS PLUS requires a particularly high brake power boost, PRE-SAFE® is activated at the same time.
X
Keep constant pressure on the brake pedal until the emergency braking situation is over. During this process, the ABS prevents the wheels from locking up.
The brakes will resume normal operation after
the brake pedal is released
no obstacles are detected in your path
the system no longer senses a risk of a collision
BAS PLUS is then deactivated.
BAS PLUS can react to stationary obstacles such as standing or parked vehicles at road speeds of up to approximately 40 mph (70 km/h).
BAS PLUS can only assist you when the radar sensors are switched on and functional. You can check whether the sensors are active by switching on DISTRONIC PLUS (Y page 130) or using the Radar sensors function (Y page 125) in the instrument cluster control system.
Warning!
G
BAS PLUS will only respond with brake assistance if it has clearly detected an object. Detection can be impeded by
dirty or covered sensors
snowfall or heavy rain
disturbance from other radar sources
strong radar reflection such as in parking garages
BAS PLUS uses radar signals that are not reflected well by narrow objects and absorptive materials. For this reason BAS PLUS will not react to persons, animals, and approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles driving in front of you, such as motorcycles and vehicles driving offset from your vehicle center.
Driving safety systems
After a hard collision or damage to the front of the vehicle from an accident, have the adjustment and operation of the radar sensors checked by an authorized Mercedes­Benz Center.
If BAS PLUS is not available due to a radar sensor malfunction, the braking system will continue to function normally with full brake boost and full standard BAS function.

Adaptive Brake

Adaptive Brake provides a high level of braking safety as well as increased braking comfort. Adaptive Brake takes driver and vehicle characteristics into consideration, thus achieving an optimal braking effect.
In addiditon, Adaptive Brake provides the HOLD function (Y page 141) and the hill-start assist system (Y page 141).
For more information on the brake system, see (Y page 218).
EBP
Observe Safety notes, see page 59.
G
The Electronic Brake Proportioning (EBP) enhances braking effectiveness by allowing the rear brakes to supply a greater proportion of the braking effort in straight-line braking without a loss of vehicle stability.
Warning!
G
If the EBP malfunctions, the brake system will still function with full brake boost. However, the rear wheels could lock up during emergency braking situations, for example. You could lose control of the vehicle and cause an accident.
Adapt your driving style to the changed driving characteristics.

ESC
Observe Safety notes, see page 59.
G
The Electronic Stability Control (ESC) is operational as soon as the engine is running. It monitors the vehicle’s traction (force of adhesive friction between the tires and the road surface) and handling.
The ESC recognizes that the vehicle deviates from the direction of travel as intended by the driver. By applying brakes to individual wheels and by limiting the engine output, the ESC works to stabilize the vehicle. The ESC is especially useful while driving off and on wet or slippery road surfaces. The ESC also
Safety and security
stabilizes the vehicle during braking and steering maneuvers.
The ESC warning lamp ä in the instrument cluster comes on when you switch on the ignition. It goes out when the engine is running.
Warning!
G
Never switch off the ESC when you see the ESC warning lamp ä flashing in the instrument cluster. In this case proceed as follows:
When driving off, apply as little throttle as possible.
While driving, ease up on the accelerator pedal.
Adapt your speed and driving style to the prevailing road conditions.
Failure to observe these guidelines could cause the vehicle to skid. The ESC cannot prevent accidents resulting from excessive speed.
!
Because the ESC operates automatically,
the engine and ignition must be shut off (SmartKey in starter switch position 0 or 1 or KEYLESS-GO start/stop button in position 0 or 1) when the parking brake is being tested on a brake test dynamometer
or when the vehicle is being towed with one axle raised.
Active braking action through the ESC may otherwise seriously damage the brake system which is not covered by the Mercedes-Benz Limited Warranty.
!
The ESC will only function properly if you use wheels of the recommended tire size as specified in the “Technical data” section of this Operator’s Manual.
i
The DISTRONIC PLUS and cruise control switch off automatically when the ESC engages.
Electronic Traction System (ETS)
Observe Safety notes, see page 59.
G
The ETS (Electronic Traction System) is a component of the ESC. The ETS improves the vehicle’s ability to utilize available traction, especially under slippery road conditions by applying the brakes to a spinning wheel.
When you switch off the ESC, the ETS is still enabled.
Switching off the ESC
Warning!
G
The ESC should not be switched off during normal driving other than in the circumstances described below. Disabling the system will reduce vehicle stability in driving maneuvers.
Do not switch off the ESC when a spare wheel is mounted.
To improve the vehicle’s traction, switch off the ESC. This allows the drive wheels to spin and thus cut into surfaces for better grip, for example
when driving with snow chains
in deep snow
in sand or gravel
Driving safety systems
63
Warning!
G
Switch on the ESC immediately if the aforementioned circumstances do not apply anymore. Otherwise the ESC will not stabilize the vehicle when it is starting to skid or a wheel is spinning.
When you switch off the ESC,
the ESC does not stabilize the vehicle
the engine output is not limited, which allows the drive wheels to spin and thus cut into surfaces for better grip
the ETS will still apply the brakes to a spinning wheel
the ESC continues to operate when you are braking
the cruise control or the DISTRONIC PLUS cannot be activated
the cruise control or the DISTRONIC PLUS switch off if activated
i
When the ESC is switched off and one or
more drive wheels are spinning, the ESC warning lamp ä in the instrument cluster flashes. However, the ESC will then not stabilize the vehicle.
Warning!
G
When the ESC OFF warning lamp å is on, the ESC is switched off.
When the ESC warning lamp ä and the ESC OFF warning lamp å are on continuously, the ESC is not operational due to a malfunction.
When the ESC is switched off 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 ESC.
!
Avoid spinning of a drive wheel for an extended period with the ESC switched off. This may cause serious damage to the drivetrain which is not covered by the Mercedes-Benz Limited Warranty.

PRE-SAFE
®
Brake
The PRE-SAFE® Brake is available in vehicles equipped with DISTRONIC PLUS. The PRE­SAFE® Brake can assist you in minimizing the risk of a rear-end collision with a vehicle in front of you. The PRE-SAFE® Brake may also reduce the severity of an accident. At speeds above approximately 20 mph (30 km/h) it will issue a warning when your vehicle is approaching the preceding vehicle very quickly. An intermittent acoustic warning sounds and the distance warning lamp · in the instrument cluster comes on.
Due to the system characteristics, warnings could be issued without cause in complex driving situations.

Immediately brake your vehicle to increase the distance between your vehicle and the vehicle driving in front of you. The warning sound is intended as a final caution that you have not interceded with your own braking inputs to avoid a potentially dangerous situation. Do not wait for the operation of the warning signal to intercede with your own braking, as that will result in potentially dangerous emergency braking which will not always result in an impact being avoided.
Tailgating increases the risk of an accident.

The PRE-SAFE® Brake may not detect narrow vehicles driving in front of you, such as motorcycles and vehicles driving offset from your vehicle center.
Warning!
G
Depending on the vehicle speed, the PRE-SAFE® Brake brakes your vehicle with a maximum of 13 ft/s2 (4 m/s2) before a possible hard stop. This corresponds to about 40% of the maximum deceleration ability of your vehicle. The driver must apply the brakes additionally in order to prevent a collision. The self-acting hard stop will be initiated when the imminent danger of a collision exists, e.g. when an evasive driving maneuver cannot avoid an accident.
To maintain the proper distance to the vehicle in front of you and thus prevent a rear-end collision, you must apply the brakes yourself.
X
Brake the vehicle immediately to avoid a collision.
Under no circumstances should the driver await the intermittent warning sound before braking. Observe the following warning note. The intermittent warning sound ceases and the distance warning lamp · goes out when the necessary distance to the vehicle ahead is again established.
The PRE-SAFE® Brake can react to stationary obstacles such as standing or parked vehicles at road speeds of up to approximately 40 mph (70 km/h).
Warning!
G
If you do not receive visual or acoustic warning signals, the PRE-SAFE® Brake may
not have recognized the collision risk
have been deactivated

Apply the brakes yourself to avoid a collision.
The PRE-SAFE® Brake does not always clearly interpret complex traffic situations. If a visual and/or acoustic warning is issued in an uncritical driving situation, or if the vehicle brakes lightly, you can interrupt the PRE­SAFE® Brake maneuver by pressing down all the way on the accelerator pedal, using kickdown, or releasing the brake pedal.
The PRE-SAFE® Brake maneuver is terminated immediately when
you avoid the obstacle by evasive steering
you drive less than 9 mph (15 km/h)
an obstacle can no longer be identified ahead of you

Safety notes

Warning!
G
In order to avoid possible loss of vehicle control the following must be done before the vehicle is put into motion:
seat adjustment
head restraint adjustment
steering wheel adjustment
rear view mirror adjustment
fastening of seat belts
Warning!
G
Controls in detail
Do not adjust the driver’s seat while driving. Adjusting the seat while driving could cause the driver to lose control of the vehicle.
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 fatal injuries. The seat backrest and seat belts provide the best restraint when the wearer is in a position that is as upright as possible and seat belts are properly positioned on the body.
Warning!
G
Your seat must be adjusted so that you can correctly fasten your seat belt.
Observe the following points:
Adjust the seat backrest until your arms are slightly angled when holding the steering wheel.
Adjust the seat to a comfortable seating position that still allows you to reach the accelerator/brake pedal safely. The position should be as far back as possible with the driver still able to operate the controls properly.
Adjust the head restraint so that it is as close to the head as possible. The center of the head restraint must support the back of the head at eye level.
Never place hands under the seat or near any moving parts while a seat is being adjusted.
Failure to do so could result in an accident and/or serious personal injury.
Warning!
G
The power seats can be operated at any time. Therefore, do not leave children unattended in the vehicle, 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.
Warning!
G
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 appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. For additional information, see “Children in the vehicle”.
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.
Warning!
G
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.
Do not drive the vehicle without the seat head restraints. Head restraints are intended to help reduce injuries during an accident.

Adaptive Highbeam Assist
The Adaptive Highbeam Assist is only available in vehicles with Bi-Xenon headlamps.
Depending on the driving and traffic situation, low-beam leveling and the high-beam headlamps are controlled via an optical sensor. The sensor is located on the front of the overhead control panel. Glare for other road users is reduced and the illumination of road ahead is improved. The transitions between low-beam and high-beam headlamps take place without a sudden change of light.
Warning!
G
The Adaptive Highbeam Assist is only an aid intended to support you while driving. The driver is and remains responsible for proper vehicle lighting in accordance with the prevailing light, sight and traffic conditions.
The system may be impaired or unavailable when
visibility is poor, e.g. due to snow, rain, fog, or heavy spray
the optical sensor area of the windshield is dirty, fogged up, or covered by a sticker for example
The system cannot recognize the following road users:
Road users without a lighting system of their own, e.g. pedestrians
Road users with dim lighting of their own, e.g. cyclists
Road users whose lighting is obstructed, e.g. road users behind a guardrail
In some seldom cases, even road users with a lighting system of their own may be recognized too late or not at all.
The automatic high-beam headlamps will then not be deactivated or it will be activated in spite of preceding or oncoming road users.
This could endanger you and/or others and cause an accident. Always pay close attention
to the traffic situation and switch off the high beam manually if necessary.
