To fold your non-touring bench seatback forward, pull up on the latch release lever while pulling the seatback toward the rear of the vehicle. 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. After the latch has been released, push the seatback toward the front of the vehicle until it locks in place. To raise the seatback, unlock the seatback latch by pushing up on the lever while pushing down on the upper edge of the seatback. Move the seatback into the upright position. Make sure the seatback is locked when it is back in the upright position. 1-6
