Before you begin to drive, move the shoulder belt 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 move it down, press the release button and move the height adjuster to the desired position.

After you move the adjuster to where you want it, try to move it down without pressing the release button to make sure it has locked into position.
