Lap Belts - Rear Center Seating Positions The lap belt in the center of the rear seat does not adjust automatically. You must adjust it to fit snugly and as low as possible around your hips. Do not wear it around your waist. Pull the belt across your hips and insert the tongue into the correct buckle on your seat until you hear a snap and feel it lock. Make sure the buckle is securely fastened. If you need to lengthen the belt, unfasten it and tip the belt tongue at a right angle to the belt. Pull the belt tongue over your lap until it reaches the buckle. If you need to shorten the belt, pull on the loose end of the webbing until the belt fits snugly. To unfasten the belt, push the release button on the buckle. This allows the tongue to unlatch from the buckle. Because the center lap belt does not have a retractor, it should be shortened and fastened when not in use. Unfastening center rear seat lap belt 16
