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. Furthermore, the restraint system can also
reduce the forces to which vehicle occupants
are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system The various components of the restraint system
work complementary to one another. They can
only perform their intended protective function
if all vehicle occupants:
R have correctly fastened their seat belt
(Y page 42)
R have correctly adjusted their seat and head
restraint (Y page 101).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 101).
Additionally, you must ensure that an airbag can
deploy freely (Y page 43).
The airbag is supplementary to a correctly fas-
tened seat belt. As an additional safety device,
the airbag increases the level of protection for
vehicle occupants in the event of an accident. If the protection provided by the seat belt is suf-
ficient, the airbags do not deploy. Furthermore,
in the event of an accident, only airbags which
provide greater protection in the given accident situation deploy. However, seat belts and air-
bags generally do not protect against objects
penetrating the vehicle from the outside.
Information on how the restraint system oper-
ates can be found in "Deployment of the seat
belt tensioner and airbags" (Y page 51).
See "Children in the vehicle" for information on
infants and children traveling with you in the
vehicle restraint systems for infants and chil-
dren(Y page 54). 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 qualified specialist workshop for details. Occupant safety
39Safety Z

Seat belts
Introduction A correctly worn seat belt is the most effective
means of restraining the movement of vehicle
occupants in the event of a collision or if the
vehicle overturns. This reduces the risk of vehi- cle occupants coming into contact with parts of
the vehicle interior or being ejected from it. The
seat belt also helps to keep the vehicle occu-
pants in the best position in relation to the air-
bag being deployed.
The seat belt system consists of:
R seat belts
R belt tensioners and belt force limiters
If the seat belt is pulled quickly or sharply by the
seat belt guide, the inertia reel locks. The belt
strap cannot be pulled out any further.
The belt tensioner tightens the seat belt in the
event of a collision so that it fits tightly across
your body. However, it does not pull the vehicle occupants back in the direction of the seat
backrest.
The belt tensioner does not, however, correct an
incorrect seat position or correct the routing of
a seat belt that is worn incorrectly.
When triggered, seat belt force limiters help to
reduce the peak force exerted by the seat belt
on the vehicle occupant.
The belt force limiters are synchronised with the front airbags, which take on a part of the decel-
eration force. This can reduce the forces to
which the vehicle occupants are subjected dur- ing an accident.
! If the co-driver's seat is not occupied, do not
engage the seat belt tongue in the buckle on
the co-driver's seat. Otherwise, the belt ten-
sioner could be triggered in the event of an
accident and would have to be replaced.
Important safety notes G
WARNING
If the seat belt is worn incorrectly, it cannot
perform its intended protective function. Fur- thermore, an incorrectly worn seat belt can
cause additional injuries, e.g. in the event of
an accident, heavy braking or sudden
changes of direction. There is an increased
risk of injury, possibly even fatal. Always ensure that all vehicle occupants have
their seat belts fastened correctly and are sit- ting properly. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder. G
WARNING
Persons under 1.50 mtall cannot wear the
seat belts correctly without an additional suit- able restraint system. If the seat belt is worn
incorrectly, it cannot perform its intended
protective function. Furthermore, an incor-
rectly worn seat belt can cause additional
injuries, e.g. in the event of an accident, heavy braking or sudden changes of direction. There
is an increased risk of injury, possibly even
fatal.
Always secure persons less than 1.50 mtall in
additional suitable restraint systems.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
R always secure the child in a child restraint
system suitable for this Mercedes-Benz vehi-
cle. The child restraint system must be appro-
priate to the age, weight and size of the child.
R always observe the instructions and safety
notes on the "Automatic front-passenger
front airbag deactivation system"
(Y page 46)
R always observe the instructions and safety
notes on "Children in the vehicle"
(Y page 54) in addition to the child restraint Occupant safety

Headbags
Headbags
:deploy in the area of the side win-
dows at the front.
When deployed, the headbag enhances the level
of protection for the head. However, it does not protect the:
R chest
R arms
In the event of a side impact, the headbag 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, a headbag may be deployed in other
accident situations (Y page 51).Automatic front-passenger front air-
bag deactivation
Introduction In order to recognise a child restraint system on
the front-passenger seat, the automatic front-
passenger front airbag deactivation system cat- egorises the person in the front-passenger seat.Depending on that result, the front-passenger
front airbag is either enabled or disabled. If a
rearward-facing child restraint system is fitted
to the front-passenger seat, the PASSENGER
AIR BAG OFF indicator lamp must light up after
the system self-test and remain lit. The front-
passenger front airbag is disabled.
The system does not disable:
R the sidebag
R the front-passenger headbag
R the seat belt tensioner
If you install a child restraint system on the
front-passenger seat, be sure to observe the correct positioning of the child restraint system.
Never place objects under or behind the child
restraint system, e.g. cushions. Fully retract the seat cushion length. The entire base of the child
restraint system must always rest on the seat
cushion of the front-passenger seat. The back-
rest of the forward-facing child restraint system
must, as far as possible, be resting on the back-
rest of the front-passenger seat. The child
restraint system must not touch the roof or be
put under strain by the head restraint. Adjust the
angle of the seat backrest and the head restraint position accordingly. Only then is the correct
function of the automatic front-passenger front airbag deactivation system guaranteed. Always
observe the information on suitable positioningof the child restraint system (Y page 58) in
addition to the child restraint system manufac-
turer's installation instructions.
