Replacing the Split Bench Seats {CAUTION: {CAUTION: 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 press rearward on the seatback to be sure it is locked. 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 installing the seat, always check to be sure that the safety belts are properly routed and attached, and are not twisted. Make sure the seatback is in the upright position and the safety belts are on the correct section of the seat. Don't put the sections of the bench seat in so they face rearward because they won't latch that way. If you want more storage room behind the second row seat, adjust each section by sliding it forward. The split bench seats have seat position labels, located on the back of each seat, showing where the seat must go. Follow that diagram. The seat must be placed in the proper location for the legs to attach correctly. Make sure the seat is in the full rear position before beginning this procedure. {CAUTION: A seat that is not locked into place properly can move around in a collision or sudden stop. People in the vehicle could be injured. Be sure to lock the seat into place properly when installing it. 1-13
