The seat belts on the front and rear seats are equipped with pretensioners. In the event of a frontal impact, the pretensioners are only activated by sensors when the corresponding belt is worn. The pretensioner tightens the belt and thus limits the forward movement of the driver or passenger.
The pretensioner can only operate once.
In mild frontal collisions, side impacts, rear impacts, rollovers, and other types of accidents where no significant forward forces are involved, the pretensioners are not activated.
NOTE: When the pretensioner is activated, a small amount of smoke will be produced. This is normal and does not indicate a fire in the vehicle.
Precautions when handling pretensioners
Pretensioners are an integral part of the seat belts installed on the vehicle seats. If you work on pretensioners and other parts of the seat belts yourself, the belts may be damaged. This may result in the pretensioners not working or not working effectively in the event of an accident.
To ensure the functionality of the pretensioners and to avoid damage to the seat belts, a number of precautions must be taken, which are known to specialist workshops.
CAUTION: Pretensioners and seat belts, including retractors, cannot be repaired.
ATTENTION: Any work on pretensioners and seat belts in general, as well as removal and installation of individual parts, must only be carried out in specialized workshops.
CAUTION: The pretensioner's protective function is only sufficient for one use. If the pretensioner has been activated, it must be replaced.
