Introduction to the restraint system
The restraint system reduces the risk of vehi-
cle occupants coming into contact with parts of the vehicle's interior in the event of an
accident. The restraint system can also reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes the:
R seat belt system
R airbags
R child restraint system
R child seat securing system
The components of the restraint system work
in conjunction with each other. They can only
offer protection if all vehicle occupants
always:
R have the seat belt correctly fastened
(Y page 46)
R have the seat and head restraint adjusted
properly (Y page 109).
As the driver, you must also make sure that
the steering wheel is also adjusted properly.
Observe the information on the correct driv-
er's seat position (Y page 108).
In addition, you must make sure that the air-
bags can inflate properly if they are deployed (Y page 48).
An airbag supplements a correctly worn seat
belt and, as an additional safety device,
increases protection for vehicle occupants in
applicable accident situations. The airbags
are not deployed, for example, in the event of an accident in which sufficient protection is
offered by the seat belt. In addition, only
those airbags, which in the applicable acci-
dent situations offer additional protection,
are deployed in the event of an accident.
However, the seat belt and airbag generally
do not protect against objects penetrating
the vehicle from the outside.
Information on how the restraint system
operates can be found under "Deployment of
belt tensioners and airbags" (Y page 57).
See "Children in the vehicle" for further infor- mation on children travelling in the vehicle as
well as on child restraint systems
(Y page 59). 42

Important safety notes
G
WARNING
If the restraint system is modified, it may no
longer work as intended. The restraint system
may then not perform its intended protective function by failing in an accident or triggering
unexpectedly, for example. There is an
increased risk of injury, possibly even fatal.
Never modify parts of the restraint system. Do not attempt to modify the wiring as well as
electronic components or their software.
If it is necessary to modify an airbag system to
accommodate a person with disabilities, con- tact a Mercedes-Benz Service Centre. Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at regular intervals while the engine is run-
ning. Therefore, malfunctions can be detec-
ted in good time.
The restraint system warning lamp in the
instrument cluster lights up when the ignition is switched on. It goes out no later than a few
seconds after the engine is started. The com- ponents of the restraint system are in opera-
tional readiness.
A malfunction has occurred if the 6
restraint system warning lamp:
R does not light up after the ignition is
switched on
R does not go out after a few seconds with
the engine running
R lights up again while the engine is running G
WARNING
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or might not be trig-
gered at all in the event of an accident with a high rate of vehicle deceleration. This can
effect belt tensioners or airbags, for example. There is an increased risk of serious or even
fatal injuries.
Have the restraint system checked and
repaired immediately at a qualified specialist
workshop.
PASSENGER AIRBAG indicator lamp
On vehicles with the automatic front-
passenger front airbag deactivation system,
the indicator lamps display the status of the
front-passenger front airbag.
R PASSENGER AIR BAG ON :lights up: the
front-passenger front airbag is enabled. If,
in the case of an accident, all deployment
criteria are met, the front-passenger front
airbag is deployed.
R PASSENGER AIR BAG OFF ;lights up: the
front-passenger front airbag is disabled. It
will then not be deployed in the event of an
accident.
Depending on the person in the front-
passenger seat, the front-passenger front air-
bag must either be disabled or enabled. You
must make sure of this both before and during
a journey.
R Children in a rearward-facing child
restraint system: the PASSENGER AIR
BAG OFF indicator lamp must be lit. The
front-passenger front airbag is disabled.
Always observe the information on the
"Automatic front-passenger front airbag Occupant safety
