How do you fix fold flat seats in Nissan Quest?

To fix the fold-flat seats in a Nissan Quest, first ensure that the seatback is fully upright. Locate the release lever or pull strap, which is typically found on the side or front of the seat. Pull the lever or strap to unlock the seat mechanism, then push the seat down flat. If the seats are stuck, check for any obstructions or debris in the mechanism and ensure that the seat is properly aligned in its tracks.
