Seats and Restraints Pretensioners work only once. If the pretensioners activate in a crash, they will need to be replaced, and probably other new parts for the vehicle's safety belt system. See Replacing Safety Belt System Parts after a Crash on page 3‑18. Here is how to install a comfort guide to the safety belt: 1. Pull the guide out from the pocket on the edge of the seatback. 3-15 Rear Safety Belt Comfort Guides Rear safety belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed and properly adjusted, the comfort guide positions the belt away from the neck and head. 2. Place the guide over the belt, and insert the two edges of the belt into the slots of the guide. 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.
