To return the seat to the passenger position on a extended model do the following: 1. Lift the floor load panels and latch them into the seatback. 2. Lift the seatback up and push rearward all the way. 3. Lower the seat cushion until it latches into position. 4. Pull forward on the seatback and up on the seat cushion to make sure the seat is securely in place. Make sure that the buckles on the driver's side seatback are accessible to the outboard and center occupant and are not under the seat cushions. To create a load floor release the panels from the seatback by pushing forward on the latch. Then fold the panels back to cover the rear seat footwell area. On regular models make sure the head restraints are returned to the upright position. 1-10
