Complaint:
The seat belt extender may be sluggish or may make noises when the extender is extending or retracting.
Cause:
When the seat belt extender toothed rack and seat belt extender motor are assembled, a preload may be produced in
the springs in the guide.
This can result in sluggishness or noises from the seat belt extender when it is operating.
In the event of complaints, it is not necessary to replace the seat belt extender motor.
Remedy:
Remove/install toothed rack of seat belt extender.
NOTE:
Removing and reinstalling the toothed rack eliminates the tension between the aforementioned components. The
springs return to their original positions.

2. Extend seat belt extender toothed rack electrically or pull it out manually
3. Grip seat belt extender toothed rack and pull out (Picture 2)
Important:

The seat belt extender toothed rack on the passenger side must be removed within 30 s (seat mat not occupied) before the retraction cycle commences. Risk of trapping!!
The retraction cycle can be extended to 1 min by weighing down the seat mat (sitting on the seat mat) on the passenger side. Risk of trapping!!
Install seat belt extender toothed rack:
4. Push in seat belt extender toothed rack carefully and without sudden movements until the first teeth mesh.
The seat belt extender toothed rack can then be retracted automatically. (Picture 3)
