To raise the rear seatback(s): { WARNING: 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. 1. Lift the seatback up and push rearward until you hear a click. Keep the safety belt clear of the seat and not twisted. The release knob on the top of the seatback has a red ring. If the seatback is not fully latched this ring will be visible. Push on the seatback until the ring is not visible. { WARNING: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always pull forward on the top of the seatback at the area of the latch to be sure it is locked. 2. Push and pull on the seatback to make sure it is locked in place. 2-13
