Seats and Restraints Safety Belt Pretensioners This vehicle has safety belt pretensioners for front outboard occupants. Although the safety belt pretensioners cannot be seen, they are part of the safety belt assembly. They can help tighten the safety belts during the early stages of a moderate to severe frontal, near frontal, or rear crash if the threshold conditions for pretensioner activation are met. And, if your vehicle has side impact airbags, safety belt pretensioners can help tighten the safety belts in a side crash or a rollover event. 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 3‑29. 3-25 Rear Safety Belt Comfort Guides This vehicle may have rear shoulder belt comfort guides. If not, they are available through your dealer. The 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. Here is how to install a comfort guide to the shoulder belt: 1. Remove the guide from its storage clip on the interior body. 2. Place the guide over the belt and insert the two edges of the belt into the slots of the guide.
