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
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 84)
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 84). You also have to make sure that an air bag can
inflate properly if deploye d( Y
page 43).
An air bag supplements ac orrectly 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 exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags
are not deployed. When an accident occurs, only
the air bags that increase protection in that par-
ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against object sp enetrating the 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).
Important safety notes
G 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 ap erson with
disabilities, contact an authorized Mercedes-
Benz Center for details. USA only: for further
information contact our Customer Assistance
Center at 1-80 0F OR-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.
