Checking Automatic Belt Device (Locking Effect)
WARNING: This page is about a different car, the 2020 Porsche Cayenne and 2019 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
The automatic belt device has two locking functions
- The first locking function is triggered by pulling the seat belt out quickly (belt extension acceleration).
Checking position
Pull the belt strap out of the automatic belt device with a strong jerk.
If no locking effect occurs, the entire seat belt and belt buckle must be replaced.
In the event of faults in the extension or retraction of the seat belt, check whether the locking lug of the automatic belt device is engaged correctly in the sheetmetal bracket on the body.
- The second locking function is triggered by a change in the sequence of vehicle movement (vehicle-dependent locking function).
