your vehicle has dual rear wheels, always use one of
me correct rotation patterns shown here when rotating
your tires.
When
you install dual wheels, be sure the vent holes in
the inner and outer wheels on each side are lined up.
After the tires have been rotated, adjust the front
and rear inflation pressures as shown on the
Certificatioflire label. Make certain that all wheel
nuts are properly tightened. See “Wheel Nut Torque”
in the Index.
’ A CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When you change a wheel, remove
any rust
or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you
need to, to get all the rust or dirt off. (See
“Changing a Flat Tire” in the Index.)

egg, fruit, fruit juice, milk, soft drinks, vomit, urine and
blood can be removed as follows:
1. Carefully scrape off excess stain, then sponge the
soiled area with cool water.
2. If a stain remains, follow the multi-purpose interior
cleaner instructions described earlier.
3. If an odor lingers after cleaning vomit or urine,
treat the area with a waterhaking soda solution:
1 teaspoon (5 ml) of baking soda to 1 cup (250 ml)
of lukewarm water.

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.
Don’t use strong soaps or chemical detergents. Use
liquid hand, dish or car washing (mild detergent) soaps.
You can get GM-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.
Cleaning Exterior LampsLenses
Use lukewarm or cold water, a soft cloth and a liquid
hand, dish or car washing (mild detergent) 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 “Appearance Care and Materials”
in
the Index.)
Your vehicle may have a “basecoatklearcoat” 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 basecoatklearcoat
paint finish.
NOTICE:
Machine compounding or aggressive polishing on
a basecoatklearcoat paint finish may dull the
finish or leave swirl marks.

Foreign materials such as calcium chloride and other
salts, ice melting agents, road oil and tar, tree sap, bird
droppings, chemicals from industrial chimneys, etc., can
damage your vehicle’s finish if they remain
on painted
surfaces. Wash the vehicle as soon as possible. If
necessary, use non-abrasive cleaners
that are marked
safe for painted surfaces to remove foreign matter.
Cleaning Aluminum 1 :els
(If Equipped)
Keep your wheels clean using a soft clean cloth with
mild soap and water. Rinse with clean water. After
rinsing thoroughly, dry with
a soft clean towel. A wax
may then be applied.
Exterior painted surfaces are subject
to aging, weather
and chemical fallout
that can take their toll over a period
of years. You can help to keep the paint finish looking
new by keeping your vehicle garaged or covered
whenever possible.
Protecting Exterior Bright Metal Parts
Bright metal parts should be cleaned regularly to keep
their luster. Washing with water is all that is usually
needed. However, you may
use chrome polish on
chrome or stainless steel trim, if necessary.
Use special care with aluminum trim.
To avoid
damaging protective trim, never use auto or chrome
polish, steam or caustic soap
to clean aluminum. A
coating of wax, rubbed to high polish, is recommended
for all bright metal
parts.
The surface of these wheels is similar to the painted
surface
of your vehicle. Don’t use strong soaps,
chemicals, abrasive polishes, abrasive cleaners or
abrasive cleaning brushes on them because you could
damage the surface.
Don’t take your vehicle through an automatic car wash
that has silicon carbide tire cleaning brushes. These
brushes can also damage the surface
of these wheels.
