Use only lukewarm or cold water, a soft cloth, and a car washing soap to clean exterior lamps, lenses, emblems, decals, and stripes.
Follow instructions under "Washing the Vehicle" previously in this section.
Lamp covers are made of plastic, and some have a UV protective coating. Do not clean or wipe them when dry.
Do not use any of the following on lamp covers:
Caution
Failure to clean lamps properly can cause damage to the lamp cover that would not be covered by the vehicle warranty.
Caution
Using wax on low gloss black finish stripes can increase the gloss level and create a non-uniform finish. Clean low gloss stripes with soap and water only.
Air Intakes
Clear debris from the air intakes, between the hood and windshield, when washing the vehicle.
Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean rubber blades using a lint-free cloth or paper towel soaked with windshield washer fluid or a mild detergent. Wash the windshield thoroughly when cleaning the blades. Bugs, road grime, sap, and a buildup of vehicle wash/wax treatments may cause wiper streaking.
Replace the wiper blades if they are worn or damaged. Damage can be caused by extreme dusty conditions, sand, salt, heat, sun, snow, and ice.
Weatherstrips
Apply weatherstrip lubricant on weatherstrips to make them last longer, seal better, and not stick or squeak. Lubricate weatherstrips at least once a year. Hot, dry climates may require more frequent application. Black marks from rubber material on painted surfaces can be removed by rubbing with a clean cloth. See Recommended Fluids and Lubricants
Tires
Use a stiff brush with tire cleaner to clean the tires.
Caution
Using petroleum-based tire dressing products on the vehicle may damage the paint finish and/ or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on the vehicle.
Wheels and Wheel Trim
Use a soft, clean cloth with mild soap and water to clean the wheels.
After rinsing thoroughly with clean water, dry with a soft, clean towel.
A wax may then be applied.
Caution
Chrome wheels and chrome wheel trim may be damaged if the vehicle is not washed after driving on roads that have been sprayed with magnesium chloride or calcium chloride. These are used on roads for conditions such as dust and ice. Always wash the chrome with soap and water after exposure.
Caution
To avoid surface damage on wheels and wheel trim, do not use strong soaps, chemicals, abrasive polishes, cleaners, or brushes. Use only GM approved cleaners. Do not drive the vehicle through an automatic car wash that uses silicon carbide tire/wheel cleaning brushes.
Damage could occur and the repairs would not be covered by the vehicle warranty.
