yellowblue Folding Rear Seats (4-Door Models) The rear seat of the 4-Door Utility or the second seat of a Suburban may have a 60/40 seat, either side may be folded down to give you more cargo space. Before folding, place the latch portion of the center safety belt in the center armrest. That way, the center safety belt will be out of the way when the seat is folded and also will be easily available for passengers to use when the seat is returned to the passenger position. Also, make sure that nothing is under or in front of the seat. When the seat is folded, it will lay flat on the floor. When folding the seat, first remove the head restraints. Push the release buttons at the bottom of each head restraint height-adjust post and slide the head restraint out of the height-adjust tubes. To fold the seat, pull up on the strap loop at the rear of the outer edge of the seat cushion. Then, pull the seat cushion up and fold it forward. After folding the seat cushion fully forward, pull the seatback forward and fold the seatback down until it is flat. Then, store the head restraints by sliding them into the rear of the seat cushion. Make sure the posts go in all the way. Set the head restraints aside for now. You will store them in their proper position after you are done folding the seat. 1-10
