Overview of occupant safety
In this section, you will learn the most impor-
tant facts about the restraint system compo-
nents of the vehicle.
The restraint system consists of:
R seat belts
R child restraint systems
R LATCH-type (ISOFIX) child seat anchors
Additional protection is provided by:
R SRS (Supplemental Restraint System)
R NECK-PRO head restraints/NECK-PRO
luxury head restraints
R air bag system components with:
- PASSENGER AIR BAG OFF indicator lamp
- front-passenger seat with Occupant
Classification System (OCS)
The different air bag systems work independ-
ently of each other. The protective functions
of the system work in conjunction with each
other. Not all air bags are always deployed in an accident. G
WARNING
Modifications to or work improperly conduc-
ted on restraint system components or their
wiring, as well as tampering with interconnec- ted electronic systems, can lead to the
restraint systems no longer functioning as
intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy inadver-
tently or fail to deploy in accidents although
the deceleration threshold for air bag deploy-ment is exceeded. Therefore, never modify
the restraint systems. Do not tamper with
electronic components or their software.

traveling with you in the vehicle restraint
systems for infants and children, see "Chil-
dren in the vehicle" (Y page 61).42

SRS (Supplemental Restraint System)
Introduction Supplemental Restraint System (SRS) with:
R The 0075 SRS warning lamp
R Air bags
R Air bag control unit (with crash sensors)
R Emergency Tensioning Device (ETD) for
seat belts
R Seat belt force limiters
SRS reduces the risk of vehicle occupants
coming into contact with parts of the vehi-
cle's interior in the event of an accident. It can also reduce the forces to which vehicle occu-
pants are subjected during an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, restraint system
components may be triggered unintentionally
or might not be triggered at all in the event of
an accident with a high rate of vehicle decel-
eration. There is an increased risk of injury,
possibly even fatal.
Have SRS checked and repaired immediately
at a qualified specialist workshop.
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 0075 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 read-
iness when the 0075SRS warning lamp goes
out while the engine is running. There is a malfunction if:
R
the 0075 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 0075SRS
warning lamp does not go out after a few
seconds
R the engine is running and the 0075SRS
warning lamp lights up again
Safety guidelines for seat belts, Emer-
gency Tensioning Devices (ETDs) and
air bags G
WARNING
R 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.
R Air bags and pyrotechnic Emergency Ten-
sioning Devices (ETDs) contain perchlorate
material, which may require special han-
dling and regard for the environment.
Check your national disposal guidelines.
California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm .
R Air bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETDthat has deployed must be replaced.
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. over the steering
wheel hub, front-passenger front air bag Occupant safety
43Safety
Z

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 breath-
ing 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 col- lision, 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 pos-
sible, still permitting proper operation of
vehicle controls. The distance from the cen- ter 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 prop-
erly 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 informa-
tion. Be sure to give the buyer this Operator's
Manual.
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 and does not indicate that there is a fire in the vehicle. The dust might cause
some temporary breathing difficulty for peo-
ple with asthma or other breathing trouble. To
avoid this, you may wish to get out of the
vehicle or open the windows as soon as it is
safe to do so. The 0075SRS 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 protec-
tion. Occupant safety

If the SmartKey is removed from the ignition
lock or is in position 0, the PASSENGER AIR
BAG OFF indicator lamp does not light up. G
WARNING
If the red 0075SRS warning lamp in the
instrument cluster and the 00730074indica-
tor lamp light up simultaneously, the OCS is
malfunctioning. 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:
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 posi-
tion him/herself in such a way as to cause the passenger's weight to be lifted from theseat 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 chap-
ter. System self-test The PASSENGER AIR BAG OFF indicator lamp
lights up if you:
R turn the SmartKey to position 1or 2in the
ignition lock
R press the KEYLESS-GO Start/Stop button
once or twice on vehicles with KEYLESS-GO
When an adult is sitting correctly on the front-
passenger seat and is categorized by the OCS system as an adult, the PASSENGER AIR BAG
OFF indicator lamp lights up and goes off
again after approximately six seconds.
If the seat is not occupied and the OCS sys-
tem classifies the front-passenger seat as
being empty, the PASSENGER AIR BAG OFF
indicator lamp will continue to light up and not go out. G
WARNING
If the 00730074indicator lamp does not illu-
minate, 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 about the OCS, see
"Problems with the Occupant Classification
System" (Y page 53). G
WARNING
Objects between the seat surface and the
child restraint system could affect OCS oper- ation. This could result in the front-passengerair bag not functioning as intended during an
accident. This poses an increased risk of
injury or even fatal injury.
Do not place any objects between the seat
surface and the child restraint system. The
entire base of the child restraint system must
always rest on the seat cushion of the front-
passenger seat. The backrest of the forwards- facing child restraint system must, as far as
possible, be resting on the backrest of the
front-passenger seat. Always comply with thechild restraint system manufacturer's instal-
lation instructions. 52

®
(anticipatory occupant
protection system)
Introduction PRE-SAFE
®
takes preemptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes !
Make sure that there are no objects in the
footwell under or behind the seats when
moving the seats back. There is a risk that
the seats and/or the objects could be dam-
aged.
Despite your vehicle being equipped with the PRE-SAFE ®
system, the possibility of per-
sonal injuries occurring as a result of an acci-
dent cannot be eliminated.
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.
Function PRE-SAFE
®
intervenes:
R in emergency braking situations, e.g. when
BAS is activated.
R in critical driving situations, e.g. when phys-
ical limits are exceeded and the vehicle
understeers or oversteers severely.
R vehicles with the Driving Assistance
package: when BAS PLUS intervenes pow-
erfully or the radar sensor system detects
an imminent danger of collision in certain
situations. If you are driving faster than approximately
20 mph (30 km/h) PRE-SAFE
®
may take the
following measures in these situations:
R the front seat belts are pre-tensioned.
R vehicles with the memory function for
the front-passenger seat: the front-
passenger seat is adjusted if it is in an
unfavorable position.
R if the vehicle skids, the side windows are
closed so that only a small gap remains.
The panorama roof with power tilt/sliding
panel is completely closed.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the belt pre-tensioning. All settings made by
PRE-SAFE ®
can then be reversed.
If the seat belt pre-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicle is stationary.
The seat belt pre-tensioning is reduced and
the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. More
information about seat-belt adjustment can
be found under "Seat-belt adjustment"
(Y page 59). NECK-PRO head restraints/NECK-
