Occupant safety
Introduction to the restraint system
The restraint system can reduce 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 comprises:
R
Seat belt system
R
Airbags
R
Child restraint system
R
Child seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if all vehicle
occupants always:
R
fasten their seat belts correctly
(
Y
page 40)
R
adjust their seat and head restraint properly
(
Y
page 99).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Y
page 99).
You also have to make sure that an airbag can
inflate properly if deployed (
Y
page 42).
An airbag supplements a correctly fastened seat
belt. As an additional safety device, the airbag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if the protection of the seat belt is sufficient
in an accident, the airbags are not deployed. In
the event of an accident, only the airbags that
increase protection in the relevant accident sit-
uation are deployed. However, seat belts and
airbags generally do not protect against objects
penetrating the vehicle from the outside.
Information on the restraint system operation
can be found under "Triggering of belt tension-
ers and airbags" (
Y
page 45).
For more information about children travelling
with you in the vehicle, see "Children in the vehi-
cle" (
Y
page 49).

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.
