Cleaning the Outside of the
Windshield and Wiper Blades

If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade 
or windshield.

Clean the outside of the windshield with a full

glass cleaning liquid. The windshield is clean if beads
do not form when you rinse it with water.

Grime from the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth soaked in full

windshield washer solvent. Then rinse the blade 
with water.

Check the wiper blades and clean them as necessary;
replace blades that look worn.

Weatherstrips

Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. See “Recommended Fluids
and Lubricants” in the Index.

Cleaning the Outside of Your Vehicle

The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.

Washing Your Vehicle

The best way to preserve your vehicle’s finish is to 
keep it clean by washing it often with lukewarm or 
cold water.

Don’t wash your vehicle in the direct rays of the sun.
Use a car washing soap. Don’t use strong soaps or
chemical detergents. Be sure to rinse the vehicle well,
removing all soap residue completely. You can get

approved cleaning products from your dealer. 

See “Appearance Care and Materials” in the Index.
Don’t use cleaning agents that are petroleum based, 
or that contain acid or abrasives. All cleaning agents
should be flushed promptly and not allowed to dry on
the surface, or they could stain. Dry the finish with a
soft, clean chamois or an all

cotton towel to avoid

surface scratches and water spotting.

High pressure car washes may cause water to enter 
your vehicle.
