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 Part C: Recommended
Fluids and Lubricants on page 6-27 .
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
GM-approved cleaning products from your dealer.
See Vehicle Care/Appearance Materials on page 5-66 .
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.
Cleaning Exterior Lamps/Lenses
Use only lukewarm or cold water, a soft cloth and a car
washing soap to clean exterior lamps and lenses.
Follow instructions under "Washing Your Vehicle."

Finish Care

Occasional waxing or mild polishing of your vehicle by
hand may be necessary to remove residue from the
paint finish. You can get GM-approved cleaning products
from your dealer. See Vehicle Care/Appearance
Materials on page 5-66 .
If your vehicle has a "basecoat/clearcoat" paint finish.
The clearcoat gives more depth and gloss to the colored
basecoat. Always use waxes and polishes that are
non-abrasive and made for a basecoat/clearcoat
paint finish.
Notice: Machine compounding or aggressive
polishing on a basecoat/clearcoat paint finish may
dull the finish or leave swirl marks.
