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. This
reduces the risk of vehicle occupants coming
into contact with parts of the vehicle interior or
being ejected from it. The seat belt also helps to
keep the vehicle occupants in the best position
in relation to the airbag being deployed.
The seat belt system consists of:
R
seat belts
R
belt tensioners for the seat belt of the driver's
seat
If the seat belt is pulled quickly or sharply from
the belt outlet, 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 driver
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.
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.
The components of the restraint system work in
conjunction with each other. They can only offer
protection if all vehicle occupants always:
R
have the seat belt correctly fastened
(
Y
page 51)
R
have the seat adjusted properly
(
Y
page 73)
Depending on the vehicle's equipment, the
head restraints must also be adjusted prop-
erly.
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 m tall 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 m tall 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
Be sure to observe the instructions and safety
notes on "Children in the vehicle"

er's operating and installation instructions for
