Seat belts

Introduction

Seat belts are the most effective means of
restricting the movement of vehicle occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi-
cle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi-
tion in relation to the air bag.
The seat belt system comprises:
Seat belts
R
Emergency Tensioning Devices and seat
R
belt force limiters
If the seat belt is pulled by the seat belt
extender quickly or with a jerky movement,
the belt retractor locks. The belt strap cannot
be extracted any further.
The Emergency Tensioning Device tightens
the seat belt in an accident, pulling the belt
close against the body. However it does not
pull the vehicle occupant back in the direction
of the backrest.
The Emergency Tensioning Device does not
correct an incorrect seat position or the rout-
ing of an incorrectly fastened seat belt.

When triggered, seat belt force limiters help
to reduce the force exerted by the seat belt on
the vehicle occupant.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This can reduce the force exerted on the vehi-
cle occupants during an accident.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle
of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of an
accident, which will then need to be
replaced.

tems is required by law in:
all 50 states

Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey.
G WARNING
If the seat belt is incorrectly fastened, it can-
not protect as intended. Furthermore, an
incorrectly fastened seat belt can cause addi-
tional injury, for example, in an accident, dur-
ing braking or when abruptly changing direc-
tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seat
belt.
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
