CORROSION PROTECTION SEAT BELTS The seat belts can be cleaned by wiping them with a sponge dampened in a mild soap solution. Allow the belts to dry completely in the shade before using them. See ''Seat belt maintenance'' in the ''Seats, restraints and supplemental air bag systems'' section of this owner's manual. WARNING Do not allow wet seat belts to roll up in the retractor. NEVER use bleach, dye, or chemical solvents to clean the seat belts, since these materials may severely weaken the seat belt webbing. MOST COMMON FACTORS CONTRIBUTING TO VEHICLE CORROSION 1. The accumulation of moisture-retaining dirt and debris in body panel sections, cavities, and other areas. 2. Damage to paint and other protective coatings caused by gravel and stone chips or minor traffic accidents. ● in areas where the temperatures stay above freezing. ● where atmospheric pollution exists. ● where road salt is used. Temperature High temperatures accelerate the rate of corrosion to those parts which are not well ventilated. ENVIRONMENTAL FACTORS INFLUENCE THE RATE OF CORROSION Moisture Accumulation of sand, dirt and water on the vehicle body underside can accelerate corrosion. Wet floor coverings will not dry completely inside the vehicle, and should be removed for drying to avoid floor panel corrosion. 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. 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 Appearance and care 7-5 Relative humidity Corrosion will be accelerated: ● in areas of high relative humidity.
