3. To raise the seatback, do the following: 3.1. Unlock the seatback latch by pulling up on the latch release lever at the right rear of the seat, while pushing down on the upper edge of the seatback. 3.2. Move the seatback into the upright position. Make sure the seatback is locked when it is back in the upright position. If you are replacing the center seat, connect the right lap-shoulder belt to the attachment on the seat cushion. If you have a safety belt guide on your seat, pull the belt through the guide before reattaching the lap-shoulder belt to the side of the seat. The release hole should be facing outward. If you installed the safety belt with the release hole facing inward (toward the seat), slide the plastic cover up so you can see the buckle. Disconnect the seat belt. Slide the cover back down and reinstall the belt correctly. {CAUTION: A safety belt that is improperly routed, not properly attached, or twisted won't 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. 1-10
