Function of the seat belt tensioner
During a frontal collision, the seat belts on the front seats are retracted au-
tomatically.
The seat belts for the occupants in the front seats are equipped with belt
tensioners. Sensors will trigger the belt tensioners during severe frontal,
side and rear collisions only if the seat belt is being worn. The belt tension-

The seat belt tensioner can be triggered only once.
The seat belt tensioners will not be triggered in the event of a light frontal,
side or rear collision, if the vehicle overturns or in situations where no large
forces act on the front, side or rear of the vehicle.
Note
● If the seat belt tensioners are triggered, a fine dust is produced. This is
normal and it is not an indication of fire in the vehicle.
● The relevant safety requirements must be observed when the vehicle or
components of the system are scrapped. Specialised workshops are famili-
ar with these regulations, which are also available to you.

Service and disposal of belt tensioners
The belt tensioners are components of the seat belts that are installed in
the seats of your vehicle. If you work on the belt tensioners or remove and
install parts of the system when performing other repair work, the seat belt
may be damaged. The consequence may be that, in the event of an acci-
dent, the belt tensioners function incorrectly or not at all.
