Shoulder Belt Height Adjuster Your vehicle has a shoulder belt height adjuster for the driver and right front passenger position. Adjust the height so that the shoulder portion of the belt is centered on your shoulder. The belt should be away from your face and neck, but not falling off your shoulder. Improper shoulder belt height adjustment could reduce the effectiveness of the safety belt in a crash. To move it down, press down on the release lever (A) and move the height adjuster to the desired position. You can move the height adjuster up just by pressing up on the shoulder belt guide. Safety Belt Pretensioners Your vehicle has safety belt pretensioners for front outboard occupants. Although you cannot see them, 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 or near frontal crash if the threshold conditions for pretensioner activation are met. Pretensioners work only once. If they activate in a crash, you will need to get new ones, and probably other new parts for your safety belt system. See Replacing Restraint System Parts After a Crash on page 1-69. Rear Safety Belt Comfort Guides Rear shoulder belt comfort guides may provide added safety belt comfort for older children who have outgrown booster seats and for some adults. When installed on a shoulder belt, the comfort guide positions the belt away from the neck and head. There is one guide for each outboard passenger position in the rear seat. Here is how to install a comfort guide to the safety belt: After you move the adjuster to where you want it, try to move it down without squeezing the release lever to make sure it has locked into position. 1-24
