Downloaded from www.Manualslib.com manuals search engine Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
( 10 000 to 1 3 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires’’ and
“Wheel Replacement” later in this section for
more information.
The purpose
of regular rotation is to achieve more
uniform wear
for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals. When rotating your tires, always
use the
correct rotation
pattern shown here.
Don’t include the compact spare tire in your
tire rotation.
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.
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.)

In many uses, these will damage your vehicle:
Alcohol
Laundry Soap
Bleach

Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and loose
dirt. Wipe vinyl or leather with a clean, damp cloth.
Your GM dealer has two cleaners, a solvent-type spot
lifter and a foam-type powdered cleaner. They will clean
normal spots and stains very well.
Do not use them on
vinyl or leather.
Here are some cleaning tips:
1. Always read the instructions on the cleaner label.
2. Clean up stains as soon as you can -- before they set.
3. Use a clean cloth or sponge, and change to a clean
area often. A soft brush may be used if stains
are stubborn.
4. Use solvent-type cleaners in a well-ventilated area
only. If you use them, don’t saturate the stained area.
5. If a ring forms after spot cleaning, clean the entire
area immediately or it will set.
Using Foam-Type Cleaner on Fabric
1. Vacuum and brush the area to remove any loose dirt.
2. Always clean a whole trim panel or section. Mask
surrounding trim along stitch or welt lines.
3. Mix Multi-Purpose Powdered Cleaner following the
directions
on the container label.
4. Use suds only and apply with a clean sponge. Don’t
saturate the material and don’t rub it roughly.
5. As soon as you’ve cleaned the section, use a sponge
to remove the suds.
6. Rinse the section with a clean, wet sponge.
7. Wipe off what’s left with a slightly damp paper towel
or cloth.
8. Dry it immediately with a blow dryer.
9. Wipe with a clean cloth.

Downloaded from www.Manualslib.com manuals search engine Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean off better with just
water and mild soap.
If
you need to use a solvent:
1.
2.
3.
4.
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper.
Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at
the
outside of the stain, “feathering” toward the center.
Keep changing to a clean section of the cloth.
When
you clean a stain from fabric, immediately
dry the area with a blow dryer to help prevent a
cleaning ring.
Fabric Protection
Your vehicle has upholstery and carpet that has been
treated with Scotchgard“ Fabric Protector, a
3M
product. It protects fabrics by repelling oil and water,
which are the carriers
of most stains. Even with this
protection,
you still need to clean your upholstery and
carpet often to keep
it looking new. Further information
on cleaning
is available by calling
1-800-433-3296 (in Minnesota, 1-800-642-6167).
Special Cleaning Problems
Greasy or Oily Stains
Stains caused by grease, oil, butter, margarine, shoe
polish, coffee with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions described earlier.
Shoe polish, wax crayon, tar and asphalt will stain if left
on a vehicle’s seat fabric. They should be removed as
soon as possible.
Be careful, because the cleaner will
dissolve them and may cause them to spread.

Downloaded from www.Manualslib.com manuals search engine 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.
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 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 basecoatklearcoat
paint finish.
I 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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.
Aluminum Wheels (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.
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.
Cleaning Tires
To clean your tires, use a stiff brush with a tire cleaner.
NOTICE:
When applying a tire dressing always take care to
wipe off any overspray or splash from all painted
surfaces on the body or wheels
of the vehicle.
Petroleum-based products may damage the
paint finish.
Sheet Metal Damage
If your vehicle is damaged and requires sheet metal
repair or replacement, make sure the body repair shop
applies anti-corrosion material
to the parts repaired or
replaced to restore corrosion protection.
