Ok, this is from the 2007 handbook, in case she doesn't have it.
Two rigid concertina plates, which cannot be separated from the vehicle, are arranged on each of the third-row seats.
- If the seats are folded, the concertina plates then cover the seats and completely conceal them.
- If the third-row seats are upright, the concertina plates are folded and provide a totally flat load surface behind the seats.
- With the third-row seats upright, alternatively the concertina plates folded in the vertical position will allow objects to be stowed.
To fold the concertina plates:
Pull on the control, the 3 sections of the plate will fold concertinawise.
To Return The Seats To The Upright Position
1. Return the second-row rigid plates to their initial position and lock them.
2. Having folded your concertina plate, pull on the control F located behind the seat backrest.
The backrest pivots rearwards, pulling the seat base with it. The seat locks in the open position.
To Stow the Third Row Seats
1. Return the second-row rigid plates to their initial position and lock them.
2. Lower the head restraints.
3. Correctly position the concertina plate vertically behind the seat.
4. Pull on the control G located at the bottom of the seat backrest. The seat unlocks.
5. Next push the backrest gently forwards. The backrest pivots, folding onto the seat base. The seat base then folds into the stowage area provided for that purpose.
6. Reposition the concertina plates over the folded seats.
Notes: Before moving the third-row seats, return the rigid plates of the second-row seats to the upright position and lock them.
Do not try to fold a third-row seat that has not first had the backrest fully locked in place.
