9 CAUTION:
When the LOW TIRE PRESSURE or FLAT TIRE message is displayed on the Driver
Information Center, your vehicle’s handling
capabilities
will be reduced during severe
maneuvers. If you drive too fast, you could lose
control
of your vehicle. You or others could be
injured. Don’t drive over
55 mph (90 km/h) when
the LOW TIRE PRESSURE or FLAT TIRE
message is displayed. Drive cautiously, and check
your tire pressures as soon as you can.
If a tire goes flat, you won’t need to stop on the side of
the road to change the tire.
You can just keep on driving.
The shorter the distance you drive and the slower the
speed, the greater the chance that the tire will not
have to be replaced.
If you drive on a deflated EMT
for
50 miles (80 km) or less and at speeds of 55 mph
(90 km/h) or less, there is a good chance that the tire can
be repaired. The tire can operate effectively with no air
pressure for up to 200 miles (320
km) at speeds up to
55 mph (90 kdh), but the tire would then have to be
replaced. When a tire is filled with air,
it provides a
cushion between the road and the wheel. Because you
won’t have this cushion when driving on a deflated tire,
try to avoid potholes that could damage your wheel and
require replacement of it.
Some road hazards can damage a tire beyond repair.
This damage could occur even before you’ve driven
on the tire in a deflated condition. When a tire has
been damaged, or if you’ve driven any distance on
a
deflated EMT, check with an authorized Goodyear
EMT Service Center to determine whether the tire can
be repaired or should be replaced. To maintain your
vehicle’s extended mobility feature, all replacement tires
must be Extended Mobility Tires.
As soon as possible,
contact the nearest authorized Chevrolet or Goodyear
EMT servicing facility for inspection and repair or
replacement. Call Chevrolet at 1-800-CHEV-USA
(1-800-243-8872) or Goodyear at 1-800-789-9878
24-hours a day for information on the location of the
nearest EMT servicing facility. In Canada, contact the
Customer Communication Center at 1-800-263-3777, or
Canadian Roadside Assistance at 1-800-268-6800. You
can also use the Goodyear number listed above to locate
an authorized EMT servicing facility.

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 the following:
0 Too much flexing
0 Too much heat
0 Tire overloading
0 Bad wear
Bad handling
0 Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
0 Bad handling
Rough ride
0 Needless damage from road hazards. When to Check
Check your tires
once a month or more.
How to Check
Use a good quality pocket-type gage to check tire
pressure.
You can’t tell if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure
to put the valve caps back on the valve stems.
They help prevent leaks by keeping out
dirt and moisture.
Tire Rotation
The tires on your Corvette are directional 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.

Downloaded from www.Manualslib.com manuals search engine 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 1/16 inch (1.6 mm) or
less of tread remaining.
You need
a new tire if any of the following statements
are true:
You can see the indicators at three or more places
You can see cord or fabric showing through the
around the tire.
tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
The tire has a bump, bulge or split.
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
your 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 an
“MS”
(for mud and snow).

Keep belts clean and dry.
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.
Cleaning Glass Surfaces
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 on
interior glass.
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 the
Windshield and Wiper Blades
If the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running,
wax, sap or other material may be on the blade
or windshield.
Clean the outside of the windshield with GM
Windshield Cleaner, Bon
Ami@ Powder (non-scratching
glass cleaning powder), GM
Part No. 1050011. The
windshield is clean if beads do not form when you rinse
it with water.
If you use a glass treatment or conditioner containing
ethyl alcohol or ethyl sulfate on your glass, be sure to
remove the acrylic roof panel, if
so equipped. These
products may damage the panel.
Grime
horn the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with a cloth
soaked in full-strength windshield
washer solvent. Then rinse the blade
with water.
Check the wiper blades and clean them as necessary;
replace blades that look worn.

NOTICE:
Conveyor systems on some automatic car washes
may damage a Corvette. They may not have
enough clearance for the undercarriage or for the
wide rear tires.
Check with the manager before using a car wash.
Cleaning Exterior LampsLenses
Use lukewarm or cold water, a soft cloth and a liquid
hand, dish or car washing (mild detergent) soap to clean
exterior lamps and lenses. Follow instructions under
“Washing Your Vehicle.”
Finish Care
Occasional waxing or mild polishing of your Corvette
by hand may be necessary to remove residue from the
paint finish. You can get GM-approved cleaning
products from your dealer.
(See “Appearance Care and
Materials” in the Index.) Your
Corvette has a “basecoatklearcoat” 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.

Add-on Electrical Equipment
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.
Accessory Power Plug

DO NOT splice wires directly into the
vehicle electrical wire harness.
If done
incorrectly, splicing may cause damage to
your electrical system and would not be
covered by the vehicle’s warranty.
The maximum load of any electrical
equipment should not exceed
15 amps.
Be sure to turn off any electrical equipment
when not in use. Leaving electrical
equipment on for extended periods of time
can drain your battery.
DO NOT use this plug if the electrical
equipment requires frequent connecting
and disconnecting. This may cause
excessive wear on the accessory plug and
damage your electrical system and the
damage would not be covered by
your warranty.
Headlamps
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.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part A: Scheduled Maintenance Services” shows
what to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment, you should
let your dealer’s service department or another qualified
service center do these jobs.
I
Performing maintenance work on a vehicle can
be dangerous. In trying to do some jobs, you can
be seriously injured.
Do your own maintenance
work only
if you have the required know-how
and the proper
tools an& equipment for the job.
If you have any doubt, have a qualified
technician
do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service information
GM publishes.
See “Service and Owner
Publications” in the Index.
“Part B: Owner Checks and Services” tells you
what should be checked and when. It also explains
what you can easily do to help keep your vehicle
in
good condition.
“Part C : Periodic Maintenance Inspections”
explains important inspections that your Chevrolet
dealer’s service department or another qualified service
center should perform.
“Part D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether you do the work
yourself or have it done.
“Part E: Maintenance Record” provides a place for
you to record the maintenance performed on your
vehicle. Whenever any maintenance is performed, be
sure to write
it down in this part. This will help you
determine when your next maintenance should be done.
In addition, it is a good idea to keep your maintenance
receipts. They may be needed to qualify your vehicle
for warranty repairs.
