Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi-cle occupant scomin ginto 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 occupant sare subjected during
an accident.
The restraint system comprises:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securings ystems
The component softhe restraint system work in
conjunction with each other .They can only
deploy their protective function if, at all times, all
vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 41)
Rhave the seat and head restraint adjusted
properly (Ypage 74)
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 (
Ypage 74).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 43).
An air bag supplement sacorrectly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupant sinthe 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 accidento ccurs,only
the air bags that increase protection in that par- ticular accidents ituation are deployed. How-
ever, seat belts and air bags generally do not
protec tagainst objects penetratin gthe vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 46).
See "Children in the vehicle" for information on
children travelin gwith you in the vehicle as well
as on child restraint systems (
Ypage 49).
Important safetyn otes
GWARNING
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
accidentort rigger unexpectedly, for example.
This poses an increased risk of injur yoreven
fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
component sortheir software.
If it is necessary to modify component softhe
restraint system to accommodate aperson
with disabilities, contact an authorized
Mercedes-Benz Center for details. USA only:

Airb ags
Introduction
The installatio npoint of an ai rbag can be rec-
ognized by the AIR BAG symbol.
An ai rbag complements the correctl yfastened
sea tbelt. It is no substitute for the sea tbelt. The
ai rb ag provides additional protection in appli-
cable accident situations.
Not al lairbags are deployed in an accident. The
different ai rbag systemsf unctionindepend-
entlyf rom one another (
Ypage 46).
However, no system available toda ycan com-
pletel yeliminate injurie sand fatalities.
It is also not possibl etoruleo utariskofi njury

When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protec tthe chest or arms.
In the event of aside impact, the window curtain
air bag is deployed on the side on which the
impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, awindow curtain air bag may be
deployed in other accident situations
(
Ypage 46).
