Appearance Care
Remember, cleaning products can be
hazardous. Some are toxic. Others can
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 closed space. When
you use anything from a container to
clean your Corvette, be sure to follow
the manufacturer’s warnings and
instructions. And always open your
doors or windows
when you’re
cleaning the inside. Never use
these to clean your vehicle:
0 Gasoline
Benzene
0 Naphtha
0 Carbon Tetrachloride
Acetone
0 Paint Thinner
0 Turpentine
Lacquer Thinner
0 Nail Polish Remover
They can all be hazardous
- some more
than others
- and they can all damage
your vehicle, too. Don’t use any
of these unless this manual
says you can. In many uses, these will
damage your vehicle:
0 Alcohol
0 Laundry Soap
0 Bleach
Reducing Agents
Cleaning the Inside of Your
Corvette
Use a vacuum cleaner often to get rid of
dust and loose dirt. Wipe vinyl or leather
with a clean, damp cloth.
Your Chevrolet dealer has two
GM
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: Always read the instructions on the
cleaner label. Clean up stains as soon as you can
-
before they set.
Use a clean cloth or sponge, and
change to a clean area often. A soft
brush may be used
if stains are
stubborn.

Downloaded from www.Manualslib.com manuals search engine 0 Use solvent-type cleaners in a
well-ventilated area only. If you use
them, don’t saturate the stained area.
If a ring forms after spot cleaning,
clean the entire area immediately or it
will set.
Using Foam-Type Cleaner on Fabric
Vacuum and brush the area to remove
any loose dirt.
Always clean a whole trim panel or
section. Mask surrounding trim along
stitch or welt lines.
Mix Multi-Purpose Powdered Cleaner
following the directions on the
container label.
Use suds only and apply with a clean
sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section,
use a sponge to remove the suds.
Rinse the section with a clean, wet
sponge.
Wipe
off what’s left with a slightly
damp paper towel or cloth.
Then dry it immediately with a blow
dryer or a heat lamp.
I NOTICE:
I
Be careful with a hair dryer or heat
lamp. You could scorch the fabric.
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 a solvent:
0
0 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 the
previous NOTICE.)
Fabric Protection
Your Corvette has upholstery and carpet
that has been treated with Scotchgard”
Fabric Protector, a 3M product.
Scotchgard
” 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, 1-800-642-6167).
Special Cleaning Problems
Greasy or oily stains:
Such as grease,
oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar
and asphalt.
Carefully scrape
off excess stain.
Follow the solvent-type instructions
described earlier.
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 careful,
because the cleaner will dissolve them
and may cause them to spread.

Soft-Touch paint surfaces in your
Corvette. For protection, use ArmorAll8
or equivalent.
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 Speaker Covers
Vacuum around a speaker cover gently,
so that the speaker won’t be damaged. If
something gets on one of them, follow the
steps under “Using Solvent-Type Cleaner
on Fabric.” Use as little solvent as you
can.
Care of Safety Belts

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.

Cleaning the Outside of Your
Corvette
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. Don’t use cleaning agents that
are petroleum-based, or 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 a
100% cotton towel to avoid surface
scratches and water spotting.
High pressure car washes may cause
water to enter your vehicle.
. . .214
NOTICE:
Conveyor systems on some
automatic car washes may damage a
Corvette. They may not have enough
clearance for the undercarriage or for
the extra wide rear tires on ZR-1
models. Check with the manager
before using a car wash.
Finish Care
3ccasional waxing or mild polishing of
your Corvette may be necessary to
-emove residue from the paint finish.
You
:an get GM approved cleaning products
?ram your dealer. (See “Appearance Care
ind Materials” in the Index.)
Your Corvette has a “basecoat/clearcoat”
Jaint finish. The clearcoat gives more
lepth and gloss to
the colored basecoat.
4lways use waxes and polishes that are
lon-abrasive and made for a
>asecoat/clearcoat paint finish.
NOTICE:
Machine compounding or aggressive
polishing on a basecoat/clearcoat
paint finish may dull the finish or
leave swirl
marks,
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. Vacuum away any dust and
other material. 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.

Downloaded from www.Manualslib.com manuals search engine To protect the convertible top:
0 After you wash the vehicle, make sure
the top is completely dry before you
lower it.
0 Don’t get any cleaner on the vehicle’s
painted finish; it could leave streaks.
0 If you decide to go through an
automatic car wash, ask the manager
if the equipment could damage your
top.
Cleaning and Storage of Your Hardtop
The optional hardtop has the same
durable finish as the painted surfaces
of
your Corvette. You can wash, polish and
wax it.
If you store the hardtop for a long time,
keep it covered in a dry place. Apply
silicone grease to all the weatherstrips.
Sngine Cleaning
Jse care when cleaning the LT5 engine.
10 not direct water into the “V” area on
he engine between the cylinder heads.
NOTICE:
I
Don’t use a cleaner with a strong
alkaline base. It will discolor the
aluminum.
4luminum Wheels
Your aluminum wheels have a protective
zoating similar to the painted surface of
your vehicle. Don’t use strong soaps,
shemicals, chrome polish,
or other
abrasive cleaners on them because you
could damage this coating. After rinsing
thoroughly, a wax may be applied.
I NOTICE:
I
Don’t use an automatic car wash that
has hard silicon carbide cleaning
brushes. These brushes can take
off
the protective coating.
rires
Your Chevrolet dealer has a GM White
Sidewall Tire Cleaner. You can
use a stiff
)rush with the cleaner.
When applying a tire dressing always take
;are to wipe
off any overspray or splash
from painted surfaces. Petroleum-based
products may damage the paint finish.
Weatherstrips
Silicone grease on weatherstrips will
make them last longer, seal better, and not
stick or squeak. Apply silicone grease
with a clean cloth at least every
six
months. During very eold, damp weather
more frequent application may be
required. (See “Recommended Fluids and
Lubricants’’ in the Index.)
Foreign Material
Calcium chloride and other salts, ice
melting agents, road oil and tar, tree sap,
bird droppings, chemicals from industrial
chimneys, and other foreign matter can
damage your vehicle’s finish if they
remain on painted surfaces. Use cleaners
that are marked safe for painted surfaces
to remove foreign matter.

Finish Damage
Any stone chips, fractures or deep
scratches
in the finish should be repaired
right away.
Minor chips and scratches can be repaired
with touch-up materials 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 with 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 vehicle washing
system can do this for you.
. . .216
Fiberglass Springs
I NOTICE:
Don’t use corrosive or acidic
cleaning agents, engine degreasers,
aluminum cleaning agents or other
harsh solvents to clean fiberglass
springs; they’ll damage the springs.
Chemical Paint Spotting
Some weather and atmospheric conditions
can create a chemical fallout. Airborne
pollutants can fall upon and attack
painted surfaces on your vehicle. This damage can take two
forms: blotchy,
ringlet-shaped discolorations, and small
irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes
this, Chevrolet 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)
Df purchase, whichever comes first.

NOTICE:
Don’t add anything electrical to
your Corvette unless you check with
your dealer first. Some electrical
equipment can damage your vehicle
and the damage wouldn’t be covered
by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Your vehicle has an air bag system.
Before attempting to add anything
electrical to your Corvette, see “Servicing
Your Air Bag-Equipped Corvette” in the
Index.

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.
There are three fuse centers on your
vehicle. One
is in the right side of your
instrument panel. Turn the knob and pull
the door to access the fuses. The other
two fuse blocks are in the
engine compartment. One is part of the
Forward Lamp wiring harness
(A), and
the other is part of the ECM-Engine
wiring harness
(B).
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 correct
size.
If you ever have a problem on the road
and don’t have a spare fuse, you can
borrow one of the correct value. 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 size you need. Replace it as soon
as you can.
Headlights
The headlight wiring is protected by a
circuit breaker
in the switch. An electrical
overload will cause the lights to go on and
off, or in some cases to remain
off. If this
happens, have your headlight wiring
checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse. If the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
If the overload is caused by some
electrical problem and not snow, etc.,
be sure to get
it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power
windows and other power accessories.
When the current load is too heavy,
the circuit breaker opens and closes,
protecting the circuit until the problem
is fixed or goes away.
