To increase your confidence in the seat belts, check the operation as follows. Grasp the shoulder belt and pull quickly forward. The retractor should lock and restrict further belt movement. If the retractor does not lock during this check, or if you have any questions about seat belt operation, see an authorized NISSAN dealer. ARS1054 ARS1239 Unfastening the seat belt To unfasten the seat belt, press the button on the buckle. The seat belt automatically retracts. Shoulder belt height adjustment (front seats only) The shoulder belt anchor height should be adjusted to the position best for you. (See ''Precautions on seat belt usage'' earlier in this section.) To adjust, pull out on the adjustment button and move the shoulder belt anchor to the desired position, so the belt passes over the center of the shoulder. The belt should be away from your face and neck, but not falling off of your shoulder. Release the adjustment button to lock the shoulder belt anchor into position. Checking seat belt operation Seat belt retractors are designed to lock seat belt movement by two separate methods: 1) When the seat belt is pulled quickly from the retractor. 2) When the vehicle slows down rapidly. 1-18 Seats, restraints and supplemental air bag systems
