The front seatbacks tilt forward to allow access to the rear of the cab.
To tilt the seatback forward, lift the lever located on the outboard side of the seat cushion.
Caution: If either seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatbacks to be sure they are locked.
To return the seatback to the upright position, push the seatback rearward until it latches. After returning the seatback to its upright position, push and pull on the seatback to make sure it is locked.
