2001 GMC Sierra 1500 Pickup Owner's Manual - Page 24

Rear Seat (Crew Cab)R The second row rear seat is a 60/40 split seat. Either side of the rear seat may be folded down to give you more cargo space. Before folding the rear seat on the driver's side, insert the two buckles into the retainer in the seatback. That way, the buckles will be out of the way when the seat is folded and will be 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 and that the head restraints are completely lowered. To fold, pull up on the strap loop at the rear 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. If the seatback cannot fold flat because it interferes with the cushion, try moving the front seat forward and/or bringing the front seatback more upright. The lever at the base of the seat must be turned rearward to release the seatback. 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. 1-11
