Temperature A temperature increase accelerates the rate of corrosion to those parts which are not well ventilated. Air pollution Industrial pollution, the presence of salt in the air in coastal areas, or heavy road salt use accelerates the corrosion process. Road salt also accelerates the disintegration of paint surfaces. CAUTION ● 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. ● Never allow water or other liquids to come in contact with electronic components inside the vehicle as this may damage them. To protect your vehicle from corrosion: ● wash and wax your vehicle often to keep the vehicle clean. ● always check for minor damage to the paint and repair it as soon as possible. ● keep drain holes at the bottom of the doors open to avoid water accumulation. ● check the underbody for accumulation of sand, dirt or salt. If present, wash with water as soon as possible. 7-6 Appearance and care
