Always push and pull on the seatback to be sure it is locked. To return the seatback(s) to the upright position, do the following: 1. Lift the seatback up and push it rearward all the way. 2. Place your hand under the front of the seat cushion and lift the cushion while moving it rearward until it latches into position. 3. Pull forward on the seatback and push down on the seat cushion to make sure the seat is securely in place. {CAUTION: A safety belt that is improperly routed, not properly attached, or twisted will not provide the protection needed in a crash. The person wearing the belt could be seriously injured. After raising the rear seatback, always check to be sure that the safety belts are properly routed and attached, and are not twisted. 16
