The automatic belt device has two locking functions
- The first locking function is triggered by pulling the seat belt out quickly (belt extension acceleration).
Test
- 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).
