subjected during an accident.
SRS warning lamp G
WARNING
If SRS is malfunctioning, child restraint
system components may be triggered
unintentionally or might not be triggered at all
in the event of an accident with ahigh rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
at aq ualified 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 0012 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than afew seconds
after the engine is started. The SRS components are in operational
readiness when the
0012SRS indicator lamp
goes out while the engine is running.
There is amalfunction if:
R the 0012 SRS warning lamp does not light
up when the ignition is switched on
R the engine is running and the 0012SRS
warning lamp does not go out after afew

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-Ben zCenter.
R Air bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the
environment. Check your national disposal
guidelines. California residents, see

WARNING
Air bagsa re designed to reduce the incidence
of injurie sand fatalities in certain situations:
R frontal impacts (driver's and front-
passenger front air bagsa nd knee bags)
R side impacts (sid eimpact air bags, window
curtai nair bags and pelvis air bags)
R rollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.
When the air bags are deployed, asmall
amount of powder is released .The powder
generally does not constitute ahealth hazard
and does not indicate that there is afire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot get
out of the vehicle after the air bag inflates,
then get fresh air by opening awindow or
door. G
WARNING
In order to reduce the potential danger of
injuries caused during the deployment of the
front air bags, the driver and front passenger
must always be correctly seated and wear
their seat belts.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body. As the air bag inflates with considerable
speed and force,
aproper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at asafe
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 ap osition that is as upright as possible
with your back against the backrest.
R move the driver's seat as far back as
possible, still permittingp roper operation
of vehicle controls. The distance from the
center of the driver's chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches (25 cm). You
should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Ben zCenter.
R do not lean your head or chest close to the
steerin gwheel or dashboard.
R only hold the steerin gwheel on the outside.
Placing hands and arms inside the rim can
increase the risk and potential severit yof
hand/arm injury if the driver fron tair bag
inflates.
R adjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
R occupants, especially children ,should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates .This could result in
serious or fatal injuries should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
infant restraint,t oddler restraint or booster
seat recommended for the size and weight
of the child.
Failure to follow these instructions can result
in severe injuries to you or other occupants. Occupant safety

The pelvis air bags deploy next to and below
the outer seat cushions. They are deployed:
R on the side on which an impact occurs
R at the start of an accident with ahigh rate
of lateral vehicle deceleration or
acceleration ,e.g. in aside impact
R independently of the use of the seat belt
R independently of the front air bags
R independently of the ETDs
If the vehicle rolls over ,the pelvis air bags are
generally not deployed. Exception: if the
system detect shigh vehicle deceleration or
acceleration in alateral direction and
determines that deploymen tcan offer
additional protection to that provide dbythe

Pelvis air bags 001Awill no tdeploy in side
impacts which do not exceed the system's
preset deployment thresholds for lateral
acceleration/deceleration .You will then be
protected by the fastened seat belt.
The pelvis air bag on the front-passenger side
is not deployed in the following situations:
R OCS has detected that the front-passenger
seat is unoccupied.
R the front-passenger seat belt is not
fastened.
The pelvis air bag on the front-passenger side
will deploy if the front-passenger seat belt is

Occupant safetySafety

Note the following important information if it
is necessary to carry achild on the front-
passenger seat:
R Your vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag and the front-
passenger knee bag in yourv ehicle when
the system senses the weight of atypical
12-month-old child or less along with the
weight of astandar dappropriate child
restraint on the front-passenger seat.
R Ac hild in arear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in acollision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place achild
in ar ear-facing child restraint in the front-
passenger seat. We therefore strongly
recommendt hat you always place achild
in ar ear-facing child restraint on the rear
seat.
R If you install arear-facing child restraint on
the front-passenger seat, make sure the
000F000B indicator lamp is illuminated,
indicating that the front-passenger front air
bag and front-passenger knee bag are
deactivated. Should the 000F000B
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodicall ycheck the
000F000B indicator lamp while driving to
make sure that the 000F000Bindicator
lamp is illuminated. If the 000F000B
indicator lamp goes out or remains out, do
not transport achild on the front-passenger
seat until the system has been repaired.
Ac hild in arear-facing child restraint on the
front-passenger seat could be seriously
injured or even killed if the front-passenger
front air bag is deployed. R
If you place achild in aforward-facing child
restraint on the front-passenger seat:
- move the seat as far back as possible
- use the proper child restraint
recommended for the age, size and
weight of the child
- secure child restraint with the vehicle's
seat belt according to the child seat
manufacturer's instructions
R For children larger than the typical 12-
month-old child, the front-passenger front
air bag and the front-passenger knee bag
may or may not be activated. G
WARNING
If the red 0012SRS warning lamp in the
instrumentc luster and the 000F000B
indicator lamp light up simultaneously ,the
OCS is malfunctioning. The front passenger
front air bag and the front passenger knee bag
will be deactivated in this case. Have the
system checked by qualified technicians as
soon as possible. Contact an authorized
Mercedes-Ben zCenter.
Only have the seat repaired or replaced at an
authorized Mercedes-Ben zCenter.
In order to ensure proper operation of the air
