If the level is below the bottom of the filler plug hole,
you’ll need to add some lubricant. Add enough lubricant
to raise
the level to the bottom of the filler plug hole.
What to Use
To add lubricant when the level is low, use Axle
Lubricant (GM Part
No. 12345977) or SAE 8OW-90
GL-5 gear lubricant. To completely refill after draining,
add
4 ounces (1 18 ml) of Limited-Slip Differential
Lubricant Additive (GM Part
No. 1052358). Then fill to the bottom
of the filler plug hole with Axle Lubricant
(GM Part No. 12345977) or SAE 8OW-90 GL-5
gear lubricant.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240 000 km) whichever occurs first, if you add only
DEX-COOL’ extended life coolant.
The following explains your cooling system and how
to add coolant when it is low. If you have a problem
with engine overheating, see “Engine Overheating” in
the Index.
A
50/50 mixture of water and DEX-COOL@
coolant will:
0 Give freezing protection down to -34°F (-37°C).
8
0 Give boiling protection up to 265 “F (129” C).
Protect against rust and corrosion.
0 Help keep the proper engine temperature.
Let the warning lights and gauges work as
they should.

Downloaded from www.Manualslib.com manuals search engine Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads
are worn
and new pads are needed. The sound may come and
go or
be heard
all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
The brake wear warning sound means that soon
your brakes won’t work well. That could lead to
an accident. When you hear the brake wear warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result
in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something
is wrong with
your brakes.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7 of this
manual under Part
C “Periodic Maintenance
Inspections.”
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel.
This could be a sign of brake trouble.
Brake Adjustment
As you make brake stops, your disc brakes
automatically adjust for wear.

Downloaded from www.Manualslib.com manuals search engine 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.
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 (straight ahead) traction tests and does not
include cornering (turning) traction.

If a ring forms after spot cleaning, clean the entire
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).

Downloaded from www.Manualslib.com manuals search engine Your Corvette has a “basecoatlclearcoat” 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.
NOTICE: I
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.
To protect the convertible top:
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;
If you decide to go through an automatic car wash,
ask the manager if the equipment could damage
your top. it could leave streaks.

The headlamp wiring is protected by a circuit breaker.
An electrical overload will cause the lamps to go on and
off, or in some cases to remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wipers
The windshield wiper motor is protected by a fuse and
an internal circuit breaker. 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 seats 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.
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. 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 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.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
