Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of
vehicle occupants coming into contact with
parts of the vehicle's interior in the event of an
accident. In the event of an accident, the
restraint system can also reduce the forces to
which the vehicle occupants are subjected.
The restraint system includes the following
components:
R
Seat belt system
R
Air bags
The components of the restraint system work
in conjunction with each other. They can only
deploy their protective function if, at all times,
all vehicle occupants:
R
have fastened their seat belts correctly
(Y page 41)
R
have the seat and head restraint adjusted
properly (Y page 85)
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 85).
You also have to make sure that an air bag can
inflate properly if deployed(Ypage 43).
An air bag supplements acorrectly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For
example, if, in the event of an accident, the
protection offered by the seat belt is sufficient,
the air bags are not deployed. When an acci-
dent occurs, only the air bags that increase
protection in that particular accident situation
are deployed. However, seat belts and air bags
generally do not protect against objectspene-
tratingthe vehicle from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags"
(Y page 50).
See "Children in the vehicle" for information
on children traveling with you in the vehicle as
well as on child restraint systems
(Y page 53).

WARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in
an accident or trigger unexpectedly, for
example. This poses an increased risk of
injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of the
restraint system to accommodate aperson
with disabilities, contact an authorized
Mercedes-Benz Center for details. USA only:
for further information contact our Customer
AssistanceCenter at 1-800FOR-MERCEDES
(1‑800‑367‑6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz.
