CAUTION:
Mixing tires could cause you to lose control while
driving. If you mix tires of different sizes (other
than those originally installed on your vehicle) or
types (radial and bias
-belted tires), the vehicle
may not handle properly, and you could have a
crash. Using tires of different sizes (other than
those originally installed on your vehicle) may
also cause damage to your vehicle. Be sure to use
the correct size and type tires on all four wheels.
If you feel that winter tires are needed, see ªExtended
Mobility Tiresº in the Index.
CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim flanges could develop cracks after
many miles of driving. A tire and/or wheel could
fail suddenly, causing a crash. Use only radial
-ply
tires with the wheels on your vehicle.
Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.) The
grades are molded on the sidewalls of most passenger
car tires. The Uniform Tire Quality Grading system does
not apply to deep tread, winter
-type snow tires,
space
-saver or temporary use spare tires, tires with
nominal rim diameters of 10 to 12 inches (25 to 30 cm),
or to some limited
-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to Federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.

Use a clean cloth or sponge, and change to a
clean area often. A soft brush may be used if stains
are stubborn.

If a ring forms on fabric after spot cleaning, clean the
entire area immediately or it will set.
Fabric Protection
Your vehicle has 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 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).
Cleaning Vinyl
Use warm water and a clean cloth.

Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.

Things like tar, asphalt and shoe polish will stain if you
don't get them off quickly. Use a clean cloth and a
vinyl/leather cleaner. See your dealer for this product.
Cleaning Coated Moldings
These moldings are around the hatch opening in the
rear area.

When lightly soiled, wipe with a sponge or soft
lint
-free cloth dampened with water.

When heavily soiled, use warm soapy water.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let the
leather dry naturally. Do not use heat to dry.

For stubborn stains, use a leather cleaner. See your
dealer for this product.

Never use oils, varnishes, solvent
-based or abrasive
cleaners, furniture polish or shoe polish on leather.

Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the
finish, it can harm the leather.

6-61 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 ªAppearance Care and Materialsº
in the Index.)
Your vehicle has a ªbasecoat/clearcoatº 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.
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.
Cleaning Your Convertible Top
Your convertible top should be cleaned often. If you use
an automatic car wash, use one with water jets and
hanging cloths. High pressure car washes may cause
water to enter your vehicle.
When you hand wash the top, do it in partial shade. Use
a mild soap, lukewarm water and a soft sponge. A
chamois or cloth may leave lint on the top, and a brush
can chafe the threads in the top fabric. Don't use
detergents, harsh cleaners, solvents or bleaching agents.
Wet the entire vehicle and wash the top evenly to avoid
spots or rings. Let the soap remain on the fabric for a
few minutes. When the top is really dirty, use a mild
foam
-type cleaner. Thoroughly rinse the entire vehicle,
then let the top dry in direct sunlight.

6-68 Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of maxi
-fuses,
mini
-fuses and circuit breakers. This greatly reduces the
chance of fires caused by electrical problems.
Look at the silver
-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one that has the same
amperage. Just pick some feature of your vehicle that
you can get along without
-- like the radio or cigarette
lighter
-- and use its fuse, if it is the correct amperage.
Replace it as soon as you can.Instrument Panel Fuse Block
The instrument panel fuse
block is located on the
passenger's side of the
vehicle, under the
instrument panel and under
the toe
-board.
Remove the toe
-board and carpet covering to access the
fuse block. Then turn the fuse block door knob and pull
the door to access the fuses.

Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts. If you see anything that might
keep a safety belt system from doing its job, have it
repaired. Have any torn or frayed safety belts replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag system
does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace blade
inserts that appear worn or damaged or that streak or
miss areas of the windshield. Also see ªWiper Blades,
Cleaningº in the Index.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. (See ªRecommended Fluids and Lubricantsº in
the Index.)Manual Transmission Check
Check the transmission fluid level; add if needed. See
ªManual Transmission Fluidº in the Index. Check for
leaks. A fluid loss may indicate a problem. Have the
system inspected and repaired if needed.
Automatic Transmission Inspection
It is not necessary to check the transmission fluid level.
A transmission fluid leak is the only reason for fluid
loss. Check for leaks. If a leak occurs, take the vehicle to
your Chevrolet dealership Service Department and have
it repaired as soon as possible.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part D.
Body Lubrication Service
Lubricate all body door hinges. Also lubricate all hinges
and latches, including those for the hood, rear
compartment, console door and any folding seat
hardware. Part D tells you what to use. More frequent
lubrication may be required when exposed to a
corrosive environment.
