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.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on
a specified government test course. For
example, a tire graded 150 would wear one and a half
(1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices and differences
in
road characteristics and climate.
Traction - A, B, C
The traction grades, from highest to lowest, are A, B, and
C, and they represent the tire’s ability to stop on wet
pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete.
A tire marked
C may have poor traction performance.
Warning: The traction grade assigned to this tire is based
on braking (straightahead) traction tests and does not
include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under
controlled conditions on
a specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to ,sudden tire failure.
The grade C corresponds to a level of performance
which all passenger car tires must meet under the
Federal Motor Vehicle Safety Standard
No. 109.

area immediately or it will set.
Fabric Protection
Your Corvette 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.
0 Rub with a clean, damp cloth to remove dirt. You
may have to do it more than once.
0 Things like tar, asphalt and shoe polish will stain if
you don't get them off quickly. Use a clean cloth and
a GM Vinylkeather Cleaner or equivalent product.
Cleaning Coated Moldings
These moldings are around the hatch opening in your
Corvette's rear area.
0 When lightly soiled, wipe with a sponge or soft
lint-free cloth dampened with water.
0 When heavily soiled, use warm soapy water.
You can remove scratches from a coated molding by
wiping briskly with the solvent-type cleaner described
earlier. If a ring forms, repeat the procedure over a larger
area, wiping toward the center of the ring.
If the ring
still remains, wipe the whole molding.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap.
For stubborn stains, use a GM Vinylkeather Cleaner
Never use oils, varnishes, solvent-based or abrasive
or
equivalent product.
cleaners, furniture polish or shoe polish on leather.
0 Soiled leather should be cleaned immediately. If dirt is
allowed to work into the finish, it can harm the leather.

Downloaded from www.Manualslib.com manuals search engine Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones or
waxes may cause annoying reflections in the windshield
and even make it difficult to see through the windshield
under certain conditions.
Cleaning Soft-Touch Paint Surfaces
Use only mild soap and water to clean the Soft-Touch
paint surfaces in your Corvette.
Cleaning Speaker Covers
Vacuum around a speaker cover gently, so that the
speaker won’t be damaged. Some spots and stains will
clean off better with just water and mild soap. If
something gets on one of them and you need to use a
solvent, follow these steps:
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.
Care of Safety Belts
Keep belts clean and dry.
I
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash they might not be able to provide adequate protection. Clean
safety belts only with mild soap and lukewarm
water.
Glass
Glass should be cleaned often. GM Glass Cleaner (GM
Part
No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films.
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 temporary license should not be attached across the
defogger grid.

Downloaded from www.Manualslib.com manuals search engine Your Corvette 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 Corvette 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.
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.
When you clean the top, put one hand under it to
support it. 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.
To protect the convertible top:
0
0
0
After you wash the vehicle, make sure the top is
completely dry before
you lower it.
Don’t get any cleaner on the vehicle’s painted finish;
it could leave streaks.
If you decide to go through an automatic car wash,
ask the manager if the equipment could damage
your top.

Downloaded from www.Manualslib.com manuals search engine 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 interior fuse center is on the right side of your
instrument panel. Turn the knob and pull the door
to
access the fuses.
