Tire Chains
If your vehicle has dual wheels or LT265175R16 size tires, don’t use tire
chains; they can damage your vehicle.
__ you don’t have dual wheels or if you have a tire size other than
LT265/75R16, use tire chains only when you must. Use only
SAE
“S” type chains that are the proper size for your tires. Install \
them on the
tires of the rear axle. 3
Tighten the as tightly as possible with the ends securely fastened. Drive I
slowly and TOIIOW the chain manufacturer’s instructions. If you can hear the
chains contacting your vehicle, stop and retighten them.
If the contact
continues, slow down until
it stops. Driving too fast with chains on will ’
nage your vehicle.
1 CAUTION
Appearance Cam
I
Cleaning products can be hazardous. Some are toxic. Others can \
L burst into flame if you strike a match or get them on a hot part of
the vehicle. Some are dangerous
if you breathe their fumes in a
zlosed space. When you use anything in a container to clean your
vehicle, be sure
to follow the instructions. And always open your
doors or windows when you’re cleaning the inside.
I ter use these to clean your vehicle:
Gasoline
Benzene
Naphtha
Carbon Tetrachloride
Acetone
Paint Thinner
Turpentine
Lacquer Thinner
Nail Polish Remover
They can all be hazardous-some more than others-and they can
all damage your vehicle, too.

Service & Appearance Care
Rinse the section with a clean, wet sponge.

Then dry it immediately with an air hose, a hair dryer or a heat lamp.

Wipe with a clean cloth.
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 it, then:
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 an
air hose, hair dryer,
or heat lamp to help prevent a cleaning ring. (See
previous NOTICE.)
Fabric Protection
Your vehicle has upholstery that has been treated with ScotchgardTM \
Fabric
Protector, a
3M product. ScotchgardTM 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 often
to keep it looking new.
Further information on cleaning is available by calling 1-800-433-3296
(in
Minnesota, 1-800-642-61 67).
Special Cleaning Problems
Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic creams, vegetable oils, wax c\
rayon, tar
and asphalt.
Carefully scrape off excess stain.
Then follow the solvent-type instructions above.
Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon as possible. Be c\
areful,
because the cleaner will dissolve them and may cause them to bleed.

Service & Appearance Care
Don’t use abrasive cleaners on glass, because they may cause\
scratches.
Avoid placing decals on the inside rear window, since they may\
have to be
scraped
off later. If abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged. Any tempor\
ary
license should not be attached across the defogger grid.

Clean the blade by wiping vigorously with a cloth soaked

Wiper blades should be checked on a regular basis and replaced\
when worn.
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 (\
non-detergent)
soaps. Don’t use cleaning agents that contain acid or abrasi\
ves.
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 a 100% cotton
towel to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water to enter your veh\
icle.
Finish Care
Occasional waxing or mild polishing of your vehicle may be necessary to
remove residue from the paint finish. You can get
GM approved cleaning
products from your dealer. (See “Appearance Care and Materia\
ls’’ in the Index,)
Your vehicle (except
C 3500 HD) has a “basecoat/clearcoat” paint finish The
clearcoat gives more depth and gloss to the colored basecoat.

Service & Appearance Care
Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
right away. Bare metal will corrode quickly and may develop into a major
repair expense.
Minor chips and scratches can be repaired with touch-up materia\
ls available
from your dealer or other service outlets. Larger areas of finish damage can
be corrected
in your dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust control can \
collect on the
underbody.
If these are not removed, accelerated corrosion (rust) can occur \
on the underbody parts such as fuel lines, frame, floor pan, \
and exhaust
system even though they have corrosion protection.
At least every spring, flush these materials from the underbody wi\
th plain
water. Clean any areas where mud and other debris can collect.\
Dirt packed
in closed areas of the frame should be loosened before being flushed. Your
dealer or an underbody washing system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a chemical fallout.
Airborne pollutants fall upon and attack painted surfaces on yo\
ur vehicle. This
damage
can take two forms: blotchy, ringiet-shaped discolorations, and small\

irregular dark spots etched into the paint surface.
Although no defect in the paint job causes this, General Motors will repair, at
no charge to the owner, the surfaces of new vehicles damaged by this fallout
condition within
12 months or 12,000 miles (20 000 km) of purchase,
whichever comes first. This applies only to materials manufactured and
sold
by General Motors. Bodies, body conversions or equipment not made or sold
by General Motors are not covered.
