To increase your confidence in the seat belts, check the operation as follows: . Grasp the shoulder belt and pull forward quickly. The retractor should lock and restrict further belt movement. See a GT-R certified NISSAN dealer for assistance with purchasing an extender if an extender is required. WARNING . Only NISSAN seat belt extenders, made by the same company which made the original equipment seat belts, should be used with the NISSAN seat belts. Adults and children who can use the standard seat belt should not use an extender. Such unnecessary use could result in serious personal injury in the event of an accident. Never use seat belt extenders to install child restraints. If the child restraint is not secured properly, the child could be seriously injured in a collision or a sudden stop. If the retractor does not lock during this check or if you have any question about seat belt operation, see a GT-R certified NISSAN dealer. . Shoulder belt arm (for front seats) Before fastening the seat belt, pull the shoulder belt arm forward until it clicks at the detent position. The arm can also be folded down to allow rear seat passengers easier access. Pulling the arm forward will allow an easy access to the belt. . SEAT BELT EXTENDERS If, because of body size or driving position, it is not possible to properly fit the lap-shoulder belt and fasten it, an extender that is compatible with the installed seat belts is available that can be purchased. The extender adds approximately 8 in (200 mm) of length and may be used for either the driver or front passenger seating position. SEAT BELT MAINTENANCE . To clean the seat belt webbing, apply a mild soap solution or any solution recommended for cleaning upholstery or carpets. Then, wipe with a cloth and allow the seat belts to dry in the shade. Do not allow the seat belts to retract until they are completely dry. 1-12 Safety - Seats, seat belts and supplemental restraint system
