i This Operator’s Manual describes all
features, standard or optional, potentially available for your vehicle at the time of purchase. Please be aware that your vehicle might not be equipped with all features described in this manual.
Occupant safety Introduction In this section you will learn the most important facts about the restraint system components of the vehicle. The restraint systems are: RSeat belts RChild restraints RLower Anchors and Tethers for CHildren
(LATCH)
Additional protection potential is provided by: RSupplemental Restraint System (SRS) with
- Air bags - Air bag control unit (with crash sensors) - Emergency Tensioning Device (ETD) for
seat belts
- Seat belt force limiter
RNECK-PRO active front head restraints RPreventive occupant safety (PRE-SAFE®) RAir bag system components with
- Front passenger front air bag off
indicator lamp
- USA only: Front passenger seat with
Occupant Classification System (OCS) - Canada only: Front passenger seat with BabySmart™ air bag deactivation system Although the systems are independent, their protective functions work in conjunction with each other.
2009-03-23T09:22:52+01:00 - Seite 36
Version: 2.11.8.1
G Warning! 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 55) for information on Rinfants and children traveling with you in
the vehicle
Rrestraint 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 + 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 + is not lit while the engine is running. A malfunction in the system has been detected if the SRS indicator lamp + Rfails to go out after approximately
4 seconds after the engine was started
Rdoes not come on at all Rcomes on after the engine was started or

Version: 2.11.8.1
G Warning! The SRS self-check has detected a malfunction when the SRS indicator lamp +: Rdoes not come on at all Rdoes not go out after 4 seconds after the
engine was started
Rcomes on 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 G Warning! Air bags are designed to reduce the potential of injury and fatality in certain Rfrontal impacts (front air bags) Rside impacts (side impact air bags and
window curtain air bags)
Rrollovers (window curtain air bags) However, no system available today can completely eliminate injuries and fatalities.
Occupant safety

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. G Warning! 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: RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RMove 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

you have any difficulties, please contact an authorized Mercedes-Benz Center.
RDo not lean your head or chest close to the
steering wheel or dashboard.
RKeep 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.
RAdjust the front passenger seat as far as
possible rearward from the dashboard when the seat is occupied.
ROccupants, 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 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.
RCanada only: Children 12 years old and under must never ride in the front seat, except in a Mercedes-Benz authorized BabySmart™ compatible child seat, which operates with the BabySmart™ air bag deactivation system installed in the vehicle to deactivate the front passenger front air bag when it is installed properly. Otherwise they will be struck by the air bag when it inflates in a crash. If this happens, serious or fatal injury will result.
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. G Warning! 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 bag- related 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)
(2)
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. Always wear seat belts properly.
Air bags are designed to deploy only in certain Rfrontal impacts (front air bags) Rside impacts (side impact and window curtain air bags) which exceed preset deployment thresholds
Rrollovers (window curtain air bags) 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

Version: 2.11.8.1
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 G Warning! RDamaged 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.
RAir 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.
RAir 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 pre-tensioners in addition to the pyrotechnic ETDs.
RDo not pass seat belts over sharp edges.
They could tear.
RDo not make any modification that could
change the effectiveness of the seat belts. RDo not bleach or dye seat belts as this may severely weaken them. In a crash they may not be able to provide adequate protection. RNo modifications of any kind may be made
to any components or wiring of the SRS.
RDo no change or remove any component or
part of the SRS.
RDo not install additional trim material, seat
covers, badges, etc. over the steering wheel hub, front passenger front air bag
Occupant safety
39
cover, outboard sides of the seat backrests, door trim panels, or door frame trims.
RDo not install additional electrical/
electronic equipment on or near SRS components and wiring.
RKeep area between air bags and occupants
free of objects (e.g. packages, purses, umbrellas, etc.).
RDo 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.
RAir bag system components will be hot after an air bag has inflated. Do not touch them.
RNever place your feet on the instrument panel, dashboard, or on the seat. Always keep both feet on the floor in front of the seat.
RImproper 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.
RFor 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.
RGiven 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.

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. Vehicles with OCS, USA only: 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). Vehicles with OCS, USA only: The lighter the front passenger-side occupant, the higher the vehicle deceleration rate required for second

Occupant Classification System The Occupant Classification System (OCS) is standard equipment in USA. The 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 Rthe front passenger side impact air bag Rthe window curtain air bag Rthe Emergency Tensioning Devices (ETDs) To be classified correctly, the front passenger must sit Rwith the seat belt properly fastened Rin a position that is as upright as possible
with the back against the seat backrest
Rwith 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. Furthermore, the occupant weight may appear to increase or decrease due to the following: objects hanging on the seat, lodged underneath the seat, stuffed between the seat and middle console or the seat and door, other passengers pushing on the seat, or
objects applying pressure to the back of the
seat. Always make sure the seat has
clearance in all directions at all times.
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 42
indicator lamp as an indication of whether or
not the front passenger is properly
positioned.
G Warning!
If the 42 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 42 indicator lamp goes out,
or check whether objects are caught under or
around the seat.
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-month-
old 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 42 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 42 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
42 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
42 indicator lamp illuminated,
the front passenger front air bag is
deactivated. With the 42
indicator lamp out, the front passenger front
air bag is activated.

For more information on air bag display messages in the multifunction display, see (Y page 277). G Warning! According to accident statistics, children are safer when properly restrained in the rear seating positions than in the front seating position. Thus, we strongly recommend that children be placed in the rear seats whenever possible. Regardless of seating position, children 12 years old and under must be seated and properly secured in an appropriate infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. The infant or child restraint must be properly secured with the vehicle’s seat belt, the seat belt and top tether strap, or lower anchors and top tether strap, fully in accordance with the child seat manufacturer’s instructions. Occupants, especially children, should always sit as upright as possible, wear the seat belt properly and use an appropriately sized infant restraint, toddler restraint, or booster seat recommended for the size and weight of the child. Children can be killed or seriously injured by an inflating air bag. Note the following important information when circumstances require you to place a child in the front passenger seat: RYour vehicle is equipped with air bag
technology designed to deactivate the front passenger front air bag in your vehicle when the system senses the weight of a typical 12-month-old child or less along with the weight of a standard appropriate child restraint on the front passenger seat. RA child in a rear-facing child restraint on the
front passenger seat will be seriously injured or even killed if the front passenger front air bag inflates in a collision which could occur under some circumstances, even with the air bag technology installed in your vehicle. The only means to

completely eliminate this risk is to never place a child in a rear-facing child restraint in the front seat. We therefore strongly recommend that you always place a child in a rear-facing child restraint in a backseat.
RIf you must install a rear-facing child
restraint on the front passenger seat
because circumstances require you to do
so, make sure the 42
indicator lamp is illuminated, indicating
that the front passenger front air bag is
deactivated. Should the 42
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
42 indicator lamp while
driving to make sure the 42
indicator lamp is illuminated. If the
42 indicator lamp goes out or
remains out, do not transport a child on the
front passenger seat until the system has
been repaired.
A child in a rear-facing child restraint on the
front passenger seat will be seriously
injured or even killed if the front passenger
front air bag inflates.
RIf you have to place a child in a forward-
facing child restraint on the front passenger seat, move the seat as far back as possible, use the proper child restraint recommended for the age, size and weight of the child, and secure child restraint with the vehicle’s seat belt according to the child seat manufacturer’s instructions. For children larger than the typical 12-month- old 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 Rthat 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

Rthat 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 sufficient severity to deploy the driver front air bag
The 42 indicator lamp : will be
illuminated, except with the SmartKey
removed from the starter switch or with the

G Warning!
If the red SRS indicator lamp + in the
instrument cluster and the 42
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 as soon
as possible by qualified technicians. 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: RDo not place more than 4.4 lb (2 kg) into
the parcel net on the back of the front passenger seat. Otherwise, the OCS may not be able to properly approximate the occupant weight category.
RDo not place objects under and/or around
the front passenger seat.
RDo not hang anything from or attach any
items to the seats.
RDo not stuff objects such as books between
the front passenger seat and the center console or front passenger door.
RDo not move the front passenger seat
backwards against stiff objects.
RSit with the seat belt properly fastened in a position that is as upright as possible with your back against the seat backrest. RWhile 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.
RRead 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 42 indicator lamp illuminates.

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 307). G Warning! 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.

For information on infants and children traveling with you in the vehicle and restraint systems for infants and children, see “Children in the vehicle” (Y page 55). 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
