RS reduces the risk of occupants coming into
contact with the vehicle's interior in the event
of an accident. It can also reduce the effect
of the forces to which occupants are
subjected during an accident.
SRS warning lamp G
WARNING
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
seconds
R the engine is running and the 0012SRS
warning lamp lights up again.
Safety guidelines for seat belts,
Emergency 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-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
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
R Air bags and ETDs are designed to function
on aone-time-only basis. An air bag or ETD
that has deployed must be replaced. PRE-

belt tensionersina ddition to the
pyrotechnic ETDs.
R Do not pass seat belts over sharp edges.
They could tear.
R Do not make any modification that could
change the effectiveness of the seat belts.
R Do not bleach or dye seat belts as this may
severely weaken them. In acrash they may
not be able to provide adequate protection. Occupant safety

If you sell yourv
ehicle, it is important that you
make the buyer aware of this safety
information .Besure to give the buyer this
Operator's Manual.
If the air bags are deployed, you will hear a
bang, and asmall 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 indicat ethat there
is af ire in the vehicle. The dust might cause
some temporary breathin gdifficulty 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.
You can also open the window to allow fresh
air to enter the vehicle interior. The 0012SRS
warning lamp lights up.
The air bag installation location sare
identified by the AIR BAG symbol.
The air bags are deployed if the air bag control
unit detects the need for deployment. Only in
the event of such asituation will the air bags
provide their supplemental protection.
If the driver and fron tpassenger do no twear
their seat belts, it is not possible for the air
bags to provide their supplemental
protection.
In the event of other types of impacts and
impacts below air bag deployment
thresholds, the air bags will not deploy. The
driver and passenger will then be protected
to the extent possible by aproperly fastened
seat belt. Aproperl yfastened seat beltisa lso
needed to provide the best possible
protection in arollover.
Air bags provide additional protection; they
are not, however, asubstitute for seat belts.
All vehicle occupants must fasten their seat
belts regardless of whether your vehicle is
equipped with air bags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective function for the vehicle occupants in the
event of
acrash.
i After an air bag has been deployed, have
the vehicle towed to the nearest qualified
specialist workshop, even if your vehicle is
ready to drive.
Front air bags Driver's air bag
001Adeploysinf ront of the
steering wheel; front-passenger front air
bag 0010deploysinf ront of and above the glove
box.
The front air bags increase protection for the
driver's and front passenger's head and
chest.
They are deployed:
R at the start of an accident with ahigh rate
of vehicle acceleration or deceleration in a
longitudinal direction
R in the event of certain frontal impacts
R if the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
R depending on whether the seat belt is being
used
R independently of other air bags in the
vehicle
If the vehicle rolls over, the front air bags are
generally not deployed.
Your vehicle has adaptive, two-stage front air
bags. The air bag control unit evaluates
vehicle deceleration or acceleration in the
event of acollision. In the first deployment
stage, the front air bag is filled with part of the 44

milliseconds tha tthe vehicle is being braked
or accelerated faster than originally
predicted, the front air bag is filled with the
maximum amount of propellant gas available.
The deployment of the front-passenger front
air bag is also influenced by the weight
category of the front passenger, which is
determined by the Occupant Classification
System (OCS) (Y page 47).
The lighter the passenger-side occupant, the
higher the vehicle deceleration rate required
(predicted at the start of the impact) for
second-stage inflation of the front-passenger
front air bag. In the second stage, the front
air bags are inflated with the maximum
amount of propellant gas available.
The front air bags are not deployed in
situations where alow impact severity is
predicted. You will then be protected by the
fastened seat belt.
The front-passenger front air bag will only
deploy if:
R the system, based on the OCS weight
sensor readings, detectst hat the front-
passenger seat is occupied
R the PASSENGER AIR BAG OFF indicator
lamp on the center console is not lit
(Y page 47)
R the air bag control unit predicts ahigh
impact severity
Knee bags Driver's knee bag
001Adeploysu nderneath the
steering column and front-passenger knee
bag 0010underneath the glove box. They
deploy together with the front air bags. They
are designed to operate together with the
front air bags in frontal impacts if certain
thresholds are exceeded. The knee bags
operate at best in conjunction with correctly
positioned and fastened seat belts.
Knee bags provide increased protection for
the driver and front passenger against the risk
of:
R knee injuries
R thigh injuries
R lower leg injuries
Side impact air bags G
WARNING
Using unsuitable seat covers could restrict or
even prevent deployment of the air bags
integrated into the seats. Consequently, the
air bags cannot protect vehicle occupants as
they are designed to do. In addition, the
function of the air bag deactivation system
could be restricted. This poses an increased
risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz. G
WARNING
Sensors to control the air bags are located in
the doors. Modifications or work not
performed correctly to the doors or door
paneling, as well as damaged doors, can lead
to the function of the sensors being impaired.
The air bags might therefore not function
properly any more. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. There is an increased risk of
injury.
Never modify the doors or parts of the doors.
Always have work on the doors or door
paneling carried out at aqualified specialist
workshop. Occupant safety

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
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, apassenger should not
position him/herself in such away as to
cause the passenger' sweight to be lifted
from the seat cushion as this may result in
the OCS being unable to correctly
approximat ethe passenger' sweight
category.
R Read and observe all warnings in this
chapter. Occupant safety

The system does not deactivate:
R the side impact air bag
R the pelvis air bag
R the window curtain air bag
R the Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
R with the seat belt fastened correctly
R in ap osition that is as upright as possible
with their back against the seat backrest
R with their feet on the floor The OCS weight sensor reading is affected if
the occupant's weight is transferred, e.g. by
leaning on the armrest.
If the front-passenger seat, the seat cover or
the seat cushion are damaged, have the
necessary repair work carried out at a
qualified specialist workshop.
For safety reasons, Mercedes-Benz
recommends that you only use seat
accessories that have been approved by
Mercedes-Benz.
Both the driver and the front passenger
should always observe the PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is
positioned correctly. Observe also the air bag
displaym essages that can be displayed in the
instrumentc luster (Ypage 244).
If the driver's air bag deploys, this does not
mean that the front-passenger front air bag
will also deploy.
The OCS may have detected that the seat:
R is empty or occupied by the weight of a
typical child up to twelve months old,
seated in achild restraint system
R is occupied by asmall individual, such as a
young teenager or asmall adult
R is occupied by achild in achild restraint
system whose weight is greater than that
of at ypical twelve montho ld child.
These are examples of when the OCS
deactivates the front-passenger front air bag
and front-passenger knee bag. Deactivation
takes place although the collision fulfills the
criteria for deploying the driver's air bag.
