60/40 Split Bench Seat Tahoe models: The rear seat may have a 60/40 split seat which may be folded down to give you more cargo space. Extended models: The second row rear seat of extended models may have a 60/40 split seat. Either side of the rear seat may be folded down to provide more cargo space. On Tahoe models the rear seatbacks may be equipped with rearward folding head restraints. When the seatback is being folded down, the head restraint will automatically fold rearward to allow a flat load floor for cargo or entry to the third row seat (if equipped). 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. Folding the Seatbacks {CAUTION: If the seatback isn't locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. Make sure that nothing is under or in front of the seat and that the head restraints are completely lowered. 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 seat forward and/or bring the front seatback more upright. On the passenger side of the extended models, the lever at the base of the seat must be turned rearward to release the seatback. 1-10
