Temperature A temperature increase will accelerate the rate of corrosion to those parts which are not well ventilated. CAUTION ¼ NEVER remove dirt, sand or other debris from the passenger compartment by washing it out with a hose. Remove dirt with a vacuum cleaner or broom. ¼ Never allow water or other liquids to come in contact with electronic components inside the vehicle as this may damage them. Chemicals used for road surface de-icing are extremely corrosive and will accelerate corrosion and the deterioration of underbody components such as the exhaust system, fuel and brake lines, brake cables, floor pan and fenders. In winter, the underbody must be cleaned periodically. For additional protection against rust and corrosion, which may be required in some areas, consult your local NISSAN dealer. Air pollution Industrial pollution, the presence of salt in the air in coastal areas, or heavy road salt use will accelerate the corrosion process. Road salt will also accelerate the disintegration of paint surfaces. TO PROTECT YOUR VEHICLE FROM CORROSION ¼ Wash and wax your vehicle often to keep the vehicle clean. ¼ Always check for minor damage to the paint and repair it as soon as possible. ¼ Keep drain holes at the bottom of the doors and tailgate open to avoid water accumulation. ¼ Check the underbody. If any sand, dirt or salt is accumulated, wash it off with water as soon as possible. Appearance and care 7-5
