SRS (Supplemental Restraint System)
Introduction
RS consistsof:
RTheRS warning lamp
RAir bags
RThe air bag control unit with crash sensors
REmergency Tensioning Device for the front
seat belts and the outer seat belts in the
rear
RSeat belt force limiters for the front seat
belts and the outer seat belts in the rear
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
GWARNING
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 withahigh rate of
vehicle deceleration. There is an increased
risk of injury, possibly even fatal.
Have SRS checked and repaired immediately
ataqualified 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.
TheSRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later thanafew seconds
after the engine is started.
The SRS components are in operational
readiness when theSRS indicator lamp
goes out while the engine is running.
There isamalfunction if:
RtheSRS warning lamp does not light
up when the ignition is switched on
Rthe engine is running and theSRS
warning lamp does not go out afterafew
seconds
Rthe engine is running and theSRS
warning lamp lights up again.
Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
GWARNING
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-BenzCenter.
RAir 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.
RAir bags and ETDs are designed to function
onaone-time-only basis. An air bag or ETD
that has deployed must be replaced. PRE-
SAFE®has electrically operated reversible
belt tensionersinaddition 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. Inacrash they may
not be able to provide adequate protection.

Safety

If you sell yourvehicle, 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, andasmall 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 indicatethat there
isafire in the vehicle. The dust might cause
some temporary breathingdifficulty 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. TheSRS
warning lamp lights up.
The air bag installation locationsare
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 suchasituation will the air bags
provide their supplemental protection.
If the driver and frontpassenger do notwear
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 byaproperly fastened
seat belt.Aproperlyfastened seat beltisalso
needed to provide the best possible
protection inarollover.
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 ofacrash.
iAfter 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 bagdeploysinfront of the
steering wheel; front-passenger front air
bagdeploysinfront 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:
Rat the start of an accident withahigh rate
of vehicle acceleration or deceleration in a
longitudinal direction
Rin the event of certain frontal impacts
Rif the system determines that air bag
deployment can offer additional protection
to that provided by the seat belt
Rdepending on whether the seat belt is being
used
Rindependently 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 ofacollision. In the first deployment
stage, the front air bag is filled with part of the

The Occupant Classification System (OCS)
categorizesthe occupant on the front-
passengerseat usingaweight sensor.The
front-passenger front air bag is deactivated
automatically for certain weight categories.
The PASSENGER AIR BAG OFF indicator lamp
shows you the current status.
Occupant Classification System (OCS)
categories the occupant on the front-
passenger seat usingaweight sensor.
The front-passenger front air bag and the
front-passenger knee bag are deactivated
automatically for certain weight categories.
The PASSENGER AIR BAG OFF indicator lamp
shows you the current status.
If the PASSENGER AIR BAG OFF indicator
lamp lights up, the front-passenger front air
bag and the front-passenger knee bag are
disabled.
The system does not deactivate:
Rthe side impact air bag
Rthe pelvis air bag
Rthe window curtain air bag
Rthe Emergency Tensioning Devices
To be classified correctly, the front passenger
must sit:
Rwith the seat belt fastened correctly
Rinaposition that is as upright as possible
with their back against the seat backrest
Rwith 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
displaymessages that can be displayed in the
instrumentcluster (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:
Ris empty or occupied by the weight of a
typical child up to twelve months old,
seated inachild restraint system
Ris occupied byasmall individual, such as a
young teenager orasmall adult
Ris occupied byachild inachild restraint
system whose weight is greater than that
ofatypical twelve monthold 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.
For further information,see "Air bag display
messages" (Ypage 244).

Centerbefore seating any child on the front
passenger seat.
GWARNING
Objects between the seat surface and the
child restraint system could affect the
function of the OCS. This could result in the
front-passenger frontair 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. Make
sure that the bottom and back of the child
restraint system make full contact with the
front-passenger seat cushion and backrest.
Always comply with the child restraint system
manufacturer's installation instructions.
