Improper installation of the seat will prevent correct use of the safety belts and could increase the risk of injury. Refer to the warning label on the seat belt. After installing the rear seat, make sure the safety belt is not twisted before you insert it into the detachable anchor. A twisted safety belt may cause the retractor to not work properly. Then insert the detachable anchor tongue into the detachable anchor until you hear a "click" and feel the latch engage.
