Shoulder Belt Height Adjustment Before you begin to drive, move the shoulder belt height adjuster to the height that is right for you. 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. To unlatch the belt, just push the button on the buckle. The belt should go back out of the way. Before you close the door, be sure the belt is out of the way. If you slam the door on it, you can damage both the belt and your vehicle. To move the shoulder belt height adjuster down, press the release button and move the height adjuster to the desired position. After you move the height adjuster to where you want it, try to move it down without pressing the release button to make sure it has locked into position. 1-22
