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 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.
