6-41 Extended Mobility Tires
(Except ZO6 Models)
Your vehicle, when new, had Goodyear Extended
Mobility Tires (EMT). There's no spare tire, no tire
changing equipment and no place to store a tire in
the vehicle. Extended Mobility Tires perform so well
without any air that a Tire Pressure Monitor (TPM) is
used to alert you if a tire has lost pressure.
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 km/h), 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. To locate the
nearest Chevrolet or Goodyear EMT servicing facility,
call Roadside Assistance. For phone numbers and
Roadside Assistance details, see ªRoadside Assistanceº
or ªCanadian Roadside Assistanceº in the Index. You
may also contact Goodyear, for the nearest authorized
EMT servicing facility, by calling 1
-800-789-9878.

CAUTION:
Extended mobility tires are constructed
differently than other tires and could explode
during improper service. You or others could be
injured or killed if you attempt to repair, replace,
dismount, or mount an extended mobility tire.
Let only an authorized Goodyear EMT Service
Center repair, replace, dismount and mount
extended mobility tires.
The valve stems on your extended mobility tires have
sensors that are part of the Tire Pressure Monitor
(TPM). See ªTire Pressure Monitorº in the Index.
These sensors contain batteries which are designed to
last for 10 years under normal driving conditions.
See your dealer if you ever need to have a wheel
replaced, or if the sensors ever need replacement.
NOTICE:
Using liquid sealants can damage the tire valves
and tire pressure monitor sensors in your
extended mobility tires. This damage would not
be covered by warranty. Don't use liquid sealants
in your extended mobility tires.
If you feel that winter tires are needed for your driving
conditions, Goodyear Eagle M+S EMT tires are available
in your original equipment sizes from an authorized
Goodyear EMT retailer. These tires will improve snow
traction while maintaining your Corvette's extended
mobility feature. When using winter tires on your vehicle,
be sure to use them on all four wheels. See ªBuying New
Tiresº in the Index.

6-50 Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded. 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
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.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your vehicle.
CAUTION:
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use
the correct wheel, wheel bolts and wheel nuts
for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle ground clearance and tire
clearance to the body and chassis.

Titanium Exhaust System
(Z06 Model)
Time and high performance driving conditions can
cause a color change in titanium exhaust system parts.
This is normal for a titanium surface.
Fiberglass Springs
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)
of purchase, whichever occurs first.

Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level
of emissions from your vehicle. To help protect our
environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.
Maintenance Requirements
Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed in
this manual are necessary to keep your vehicle in good
working condition. Any damage caused by failure to
follow recommended maintenance may not be covered
by warranty.

7-3 How This Section is Organized
This maintenance schedule is divided into five parts:
ªPart A: Scheduled Maintenance Servicesº explains
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.
CAUTION:
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 and equipment for the job.
If you have any doubt, have a qualified
technician do the work.
If you want to get the service information,
see ªService and Owner Publicationsº in the Index.ªPart B: Owner Checks and Servicesº tells you
what should be checked and when. It also explains
what you can easily do to help keep your vehicle in
good condition.
ªPart C: Periodic Maintenance Inspectionsº explains
important inspections that your dealer's service
department or another qualified service center
should perform.
ªPart D: Recommended Fluids and Lubricantsº lists
some recommended products necessary 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.
ªPart E: Maintenance Recordº is a place for you
to record and keep track of the maintenance performed
on your vehicle. Keep your maintenance receipts.
They may be needed to qualify your vehicle for
warranty repairs.

7-4
Part A: Scheduled
Maintenance Services
Using Your Maintenance Schedule
We at General Motors want to help you keep your
vehicle in good working condition. But we don't know
exactly how you'll drive it. You may drive very short
distances only a few times a week. Or you may drive
long distances all the time in very hot, dusty weather.
You may use your vehicle in making deliveries.
Or you may drive it to work, to do errands or in
many other ways.
Because of all the different ways people use their
vehicles, maintenance needs vary. You may need more
frequent checks and replacements. So please read the
following and note how you drive. If you have any
questions on how to keep your vehicle in good
condition, see your dealer.This part tells you the maintenance services you should
have done and when you should schedule them. If you
go to your dealer for your service needs, you'll know
that GM
-trained and supported service people will
perform the work using genuine GM parts.
The proper fluids and lubricants to use are listed in
Part D. Make sure whoever services your vehicle uses
these. All parts should be replaced and all necessary
repairs done before you or anyone else drives
the vehicle.
This schedule is for vehicles that:

carry passengers and cargo within recommended
limits. You will find these limits on your vehicle's
Tire
-Loading Information label. See ªLoading Your
Vehicleº in the Index.

are driven on reasonable road surfaces within legal
driving limits.

use the recommended fuel. See ªFuelº in the Index.
