does not light up after the ignition is switched
R
on
does not go out after a few seconds

goes out but then lights up again while the
R
engine is running, for example

WARNING
If restraint system is malfunctioning, restraint
system components may be triggered unin-
tentionally or might not be triggered at all in
the event of an accident with a high rate of
vehicle deceleration. This can affect the Emer-
gency Tensioning Device or air bag, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as
soon as possible.

Seat belts

Introduction
A correctly fastened seat belt is the most effec-
tive means of restraining the movement of vehi-
cle occupants in the event of an accident or the
vehicle rolling over. This reduces the risk of
vehicle occupants coming into contact with
parts of the vehicle interior or being thrown from
the vehicle. Furthermore, the seat belt helps to
keep the vehicle occupants in the best position
in relation to the air bag.
The seat belt system consists of:
Seat belts
R
Emergency Tensioning Devices for the front
R
seat belts
If the vehicle is equipped with a front air bag,
the seat belt system also includes a seat belt
force limiter for the corresponding seat.
On vehicles with a front-passenger bench
seat, only the seat belt of the outer front-
passenger seat has a seat belt force limiter.
If the vehicle does not have a driver's air bag, the
seat belt system does not include an Emergency
Tensioning Device or a seat belt force limiter.
If the seat belt is pulled quickly or suddenly from
the belt outlet, the inertia reel locks. The belt
strap cannot be pulled out further.
Emergency Tensioning Devices tighten the seat
belts in an accident, pulling them close against
the occupant's body. They do not, however, pull
vehicle occupants back towards the backrest.
Emergency Tensioning Devices do not correct
an incorrect seat position or incorrectly worn
seat belts.
When triggered, the seat belt force limiter
reduces the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters are synchronized
with the front air bags, which absorb part of the
deceleration force. This makes it possible to
reduce the forces to which vehicle occupants
are subjected during an accident.
The Emergency Tensioning Device of the co-
driver's seat is triggered independently of the
lock status of the seat belt.
Important safety notes
The use of seat belts and child restraint systems
is required by law in:
all 50 states
R
the U.S. territories
R
the District of Columbia
R
all Canadian provinces
R
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
abdomen or neck injuries, for example. This
