R The 0012 RS warning lamp
R Air bags
R The air bag control unit with crash sensors
R Emergency Tensioning Device for the front
seat belts and the outer seat belts in the
rear
R Seat 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 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-
SAFE ®
has electrically operated reversible
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 the SmartKey is removed from the ignition
lock or is in position 0,PASSENGER AIR BAG
OFF indicator lamp 001Adoes not light up.
The Occupant Classification System (OCS)
categorize sthe occupant on the front-
passenge rseat using aweight 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 using aweight 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:
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.
For further information ,see "Air bag display
messages" (Y page 244).
