Front Seatback Latches The front seatback folds forward to let people get into the back seat or reach the storage areabehind the seat. Your seatback will move back and forth freely, unless you come to a sudden stop. Then it will lock in place. There's one time the seatback may not fold without some help from you. That's if your vehicle is parked going down a fairly steep hill. To fold a front seatback forward, push the seatback toward the rear as you lift this latch. Then the seatback will fold forward. The latch must be down for the seat to work properly. 1-4
