Vehicle equipment
i This Operator’s Manual describes all
features, standard or optional, potentially
available for your vehicle at the time of
purchase. Please be aware that your
vehicle might not be equipped with all
features described in this manual.
Occupant safety
Introduction
In this section you will learn the most
important facts about the restraint system
components of the vehicle.    
The restraint systems are:
R Seat belts
R Child restraints
Additional protection potential is provided by:
R Supplemental  Restraint  System (SRS) with
- Air bags
- Air bag control unit (with crash sensors)
- Emergency  Tensioning  Device (ETD) for
seat belts
- Seat belt force limiter
R Air bag system components with
- Passenger front air bag off indicator lamp
- Passenger seat with  Occupant
C lassification  System (OCS)
Although the systems are independent, their
protective functions work in conjunction with
each other.
GWarning!
Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead
to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.
i See “Children in the vehicle”
( Y  page 57) for information on
R infants and children traveling with you in
the vehicle
R restraint systems for infants and children
SRS indicator lamp
The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates detection of system malfunctions.  
The SRS indicator lamp  0081 in the
instrument cluster comes on when the
ignition is switched on. It goes out no later
than a few seconds after the engine has been
started.
GWarning!
The SRS self-check has detected a
malfunction when the SRS indicator lamp
0081
R does not come on at all
R fails to go out after approximately
4 seconds after the engine was started
R comes on after the engine was started or
while driving
For your safety, we strongly recommend that
you contact an authorized Mercedes-Benz
Center immediately to have the system
checked. Otherwise the SRS may not be
activated when needed in an accident, which
could result in serious or fatal injury. The SRS
might also deploy unexpectedly and
unnecessarily which could also result in injury
as well.
In addition, improper work on the SRS creates
a risk of rendering the SRS inoperative or
causing unintended air bag deployment. Work
