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 and near frontal crash if the threshold conditions for pretensioner activation are met. And, if the vehicle has side impact airbags, safety belt pretensioners can help tighten the safety belts in a side crash. 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 3‑25. 3-21 Rear Safety Belt Comfort Guides This vehicle may have rear shoulder belt comfort guides for each outboard passenger position in the rear seat. 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 safety belt: 1. Pull the guide out from the pocket on the edge of the seatback. Squeeze the buttons (A) on the sides of the height adjuster and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the shoulder belt guide. After the adjuster is set to the desired position, try to move it down without squeezing the buttons to make sure it has locked into position.
