Shoulder Belt Height Adjuster Before you begin to drive, move the shoulder belt adjuster to the height that is right for you. To move it down, press down on the power seat recliner control and move the height adjuster to the desired position. You can move the adjuster up just by pushing up on the power seat recliner control. After you move the adjuster to where you want it, try to move it down without pushing the power seat recliner control to make sure it has locked into 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. 1-17
