If other cars are lined up to pass a
slow vehicle, wait your turn. But take
care that someone isn’t trying to pass
you as you pull out to pass the slow
vehicle. Remember to glance over
your shoulder and check the blind
spot.
Check your mirrors, glance over your
shoulder, and start your left lane
change signal before moving out of
the right lane to pass. When you are
far enough ahead
of the passed vehicle
to see its front
in your inside mirror,
activate your right lane change signal
and move back into the right lane.
(Remember that your right outside
mirror is convex. The vehicle you just
passed may seem to be farther away
from you than it really is.)
Try not to pass more than one vehicle
at a time on two-lane roads.
Reconsider before passing the next vehicle.
Don’t overtake a slowly moving
vehicle too rapidly. Even though the
brake lights are not flashing, it may be
slowing down or starting
to turn.
If you’re being passed, make it easy
for the following driver to get ahead
of you. Perhaps you can ease a little
to the right.

Loss of Control
Let’s review what driving experts say
about what happens when the three
control systems (brakes, steering and
acceleration) don’t have enough friction
where the tires meet the road to do what
the driver has asked.
In any emergency, don’t give up. Keep
trying to steer and constantly seek an
escape route or area of less danger.
Skidding
In a skid, a driver can lose control of the
vehicle. Defensive drivers avoid most
skids by taking reasonable care suited to
existing conditions, and by not
“overdriving” those conditions. But skids
are always possible.
The three types of skids correspond to
your Corvette’s three control systems.
In the braking skid your wheels aren’t
rolling. In the steering or cornering skid,
too much speed or steering in a curve
causes tires to slip and lose cornering
force. And in the acceleration skid too
much throttle causes the driving wheels
to spin.
A cornering skid
is best handled by
easing your foot
off the accelerator pedal. Remember: Any
ASR system helps avoid
only the acceleration skid. If your ASR
system is
off, then an acceleration skid is
also best handled by easing your foot off
the accelerator pedal.
If your vehicle starts to slide, ease your
foot
off the accelerator pedal and quickly
steer the way you want the vehicle to go.
If you start steering quickly enough, your
vehicle may straighten out. Always be
ready for a second skid if it occurs.
Of course, traction is reduced when water,
snow, ice, gravel, or other material is on
the road. For safety, you’ll want to slow
down and adjust your driving to these
conditions. It is important to slow down
on slippery surfaces because stopping
distance will be longer and vehicle
control more limited.

Inflation - Tire Pressure
The Tire-Loading Information label which is on the driver’s door shows the correct
inflation pressures for your tires, when they’re cold. “Cold” means your vehicle has
been sitting for at least three hours or driven no more than a mile.
For competitive driving or high-speed driving (over
150 mph or 240 krn/h), make
sure your tires are inflated to
35 psi (240 kPa). When you end this type of driving,
reduce the “cold” inflation pressures (if necessary) to those listed
on the
Tire-Loading Information label.
NOTICE:
Don’t let anyone tell you that underinflation or overinflation is all right. It’s not.
If your tires don’t have enough air (underinflation) you can get:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation), you can get:
Unusual wear
Bad handling
0 Rough ride
Needless damage from road hazards.
When to Check: Check your tires
mce
a month or more. Don’t forget
your compact spare tire. It should be at
50 psi (420 Wa).
How to Check: Use a good quality
pocket-type gauge to check tire
pressure. Simply looking at the tires
will not tell you the pressure,
=specially if you have radial tires
-
which may look properly inflated even
if they’re underinflated.
Lf your tires have valve caps, be sure to
put them back on. They help prevent
leaks by keeping out dirt and moisture.
Tire Rotation
I’he tires on your Corvette are
lirectional, asymmetrical, and are
different sizes front to rear. Due to this,
your tires should not be rotated. Each
tire and wheel should be used only in
the position it is in.

When It’s Time for New Tires
One way to tell when it’s time for new
tires is to check the treadwear indicators,
which
will appear when your tires have
only
2/32 inch (1.6 mm) or less of tread
remaining.
You need a new tire if
0 You can see the indicators at three or
You can see cord or fabric showing

through the tire’s rubber.
or snagged deep enough to show cord
or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut, or other
damage that can’t be repaired well
because of the size or location of the
damage.
Buying New Tires
To find out what kind and size of tires
you need, look at the Tire-Loading
Information label.
The tires installed on your vehicle when it
was new had a Tire Performance Criteria
Specification (TPC Spec) number on each
tire’s sidewall. When you get new tires,
get ones with that same TPC Spec
number. That way, yobr vehicle will
continue to have tires that are designed
to give proper endurance, handling,
speed rating, traction, ride and other
things during normal service on your
vehicle. If your tires have an all-season
tread design, the TPC number will be
followed by a
“MS” (for mud and snow).
If you ever replace your tires with those
not having a TPC Spec number, make
sure they are the same size, load range,
speed rating and construction type (bias,
bias-belted or radial) as your original
tires.
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.)
Treadwear
The treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions
207. . .

Downloaded from www.Manualslib.com manuals search engine Service and Appearance Care
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
iowest are:
A, B, and C. 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.
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
. . .208
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. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the
minimum required by law.
Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either separately or
in combination, can cause heat buiidup
and possible tire failure.
These grades are molded on the sidewalls
of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General Motors
performance standards and have been
approved for use on General Motors
vehicles. All passenger type
(P Metric)
tires must conform to Federal safety
requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to
give you the longest tire life and best
overall performance.
In most cases, you will not need to have
your wheels aligned again. However, if
you notice unusual tire wear or your
vehicle pulling one way or
the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels may need to be rebalanced.
Wheel- Replacement - . -
Replace any wheel that is bent, cracked or
badly rusted. If wheel nuts keep coming
loose, the wheel, wheel bolts, and wheel
nuts should be replaced. If the wheel
leaks air, replace it (except some
aluminum wheels, which can sometimes
be repaired). See your Chevrolet dealer
if any of these conditions exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted
the same way as
the one it replaces.

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.

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.

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.
