There is one guide for each outside passenger position in the rear seat. Here is how to install a comfort guide to the safety belt: 1. Remove the guide from its storage pocket on the side of the seatback. 3. Be sure that the belt is not twisted and it lies flat. The elastic cord must be under the belt and the guide on top. 2. Slide the guide under and past the belt. The elastic cord must be under the belt. Then, place the guide over the belt, and insert the two edges of the belt into the slots of the guide. 1-27
