To adjust the shoulder belt height, push the button and slide the height
adjuster up or down. Release the button and pull down on the height
adjuster to make sure it is locked in place.
Position the safety belt height adjusters so that the belt rests
across the middle of your shoulder. Failure to adjust the safety
belt properly could reduce the effectiveness of the seat belt and
increase the risk of injury in a collision.
