Re. 1.
Before parts of the 3rd seat row or the entire frame of the 3rd seat row are replaced, any existing stresses should first be eliminated. To do this, unscrew
and retighten the bolts connecting the 3rd seat row to the body.
Note:
It may be necessary to rock the seats manually in order to relieve the stresses in the 3rd seat row
Re. 2.
In the event of complaints the electric motor of the folding seat can be replaced individually rather than the entire seat frame as previously.
Re. 3.
Seat cannot be moved via the operating switches
- Check the connections of the seat adjustment motor (if the seat adjustment motor is defective, see "2")
- Check the seat adjustment operating switches
- Read out fault codes (if the seat adjustment motor is defective, see "2")
