Complaint
Cause:
- Supplier has failed to carry out adjustment
- Accumulation of tolerances
Remedy:
1. Fold the second seat row (60% side) forwards using the electrical switch (briefly press the Easy Entry switch). Immediately afterwards fold the seat row back again until the bench seat is engaged in the lock again (press and hold
the Easy Entry switch). Listen out for any scraping noises when unlocking and locking the bench seat (required for before/after noise comparison).
2. Adjust the backrest angle to its rearmost end stop (operate seat backrest adjustment switch in the door).
3. Remove the front left outer panel (panel is a push-fit) - (pic.1).
4. Drill out the blind rivets on the outer left panel (3 rivets) - (pic.2, pic.3).
5. Drill out the blind rivets on the right-hand panel (2 rivets) - (pic.4).
6. Take off panels.
7. Fold the 40% side forwards using the electrical switch (briefly press the Easy Entry switch to gain access to the
threaded connection on the inner side of the 60% bench seat).
8. Move the 60% bench seat fully forwards (press and hold the fore-aft adjustment switch in the door).
Important: It is essential that the bench seat remains engaged in the lock.
