WARNING: Position the seatbelt height adjuster so that the seatbelt rests across the middle of your shoulder. Failure to adjust the seatbelt correctly could reduce its effectiveness and increase the risk of injury in a crash.
Adjust the height of the shoulder belt so the belt rests across the middle of your shoulder. Slide the adjuster up to raise the belt. Press the button and slide it down to lower the belt.
