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 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 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 buildup and possible
tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned and
balanced carefully at the factory to give you the longest
tire life and best overall performance. Adjustments
to wheel alignment and tire balancing will not be
necessary on a regular basis. However, if you notice
unusual tire wear or your vehicle pulling to one side
or the other, the alignment might need to be checked.
If you notice your vehicle vibrating when driving on
a smooth road, the tires and wheels might need to
be rebalanced. See your dealer/retailer for proper
diagnosis.
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/retailer if any of these conditions exist.
Your dealer/retailer 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.

Windshield and Wiper Blades
Clean the outside of the windshield with glass cleaner.
Clean the rubber blades using a lint free cloth or paper
towel soaked with windshield washer fluid or a mild
detergent. Wash the windshield thoroughly when
cleaning the blades. Bugs, road grime, sap, and a
buildup of vehicle wash/wax treatments may cause
wiper streaking. Replace the wiper blades if they are
worn or damaged.
Wipers can be damaged by:
.Extreme dusty conditions
.Sand and salt
.Heat and sun
.Snow and ice, without proper removal
Removable Roof Panel
Notice: If you use a glass treatment and/or
conditioner that contains ethyl alcohol or ethyl
sulfate on the roof panel, you could damage the
panel. The repairs would not be covered by your
warranty. Only use a GM-approved glass cleaner
on the roof panel.
Special care is necessary when cleaning, removing,
and/or storing the roof panel.
.Flush with water to remove dust and dirt, then dry
the panel.
.Clean a transparent roof panel with GM Glass
Cleaner. Leave the cleaner on the panel for
one minute, then wipe the panel with a soft,
lint-free cloth. Do not use glass cleaner on a
painted roof panel.
.Do not use abrasive cleaning materials on either
type of panel.
If water drops are frequently allowed to dry on the roof
panel, impurities in the water will adhere to the top.
These impurities may etch or mar the finish. When the
panel gets wet, dry it off.
6-96
Convertible Top
The vehicle's convertible top should be cleaned often.
However, 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. Do not
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.
.Do not get any cleaner on the vehicle's painted
finish; it could leave streaks.
.If you decide to go through an automatic car wash,
ask the manager if the equipment could damage
your top.
Aluminum or Chrome-Plated Wheels
and Trim
The vehicle may have either aluminum or
chrome-plated wheels.
Keep the wheels clean using a soft clean cloth with mild
soap and water. Rinse with clean water. After rinsing
thoroughly, dry with a soft clean towel. A wax may then
be applied.
Notice: Chrome wheels and other chrome trim
may be damaged if the vehicle is not washed
after driving on roads that have been sprayed
with magnesium, calcium or sodium chloride.
These chlorides are used on roads for conditions
such as ice and dust. Always wash the vehicle's
chrome with soap and water after exposure.
Notice: Using strong soaps, chemicals, abrasive
polishes, cleaners, brushes, or cleaners that contain
acid on aluminum or chrome-plated wheels, could
damage the surface of the wheel(s). The repairs
would not be covered by the vehicle warranty.
Use only approved cleaners on aluminum or
chrome-plated wheels.
The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
6-97
Fiberglass Springs
(Composite Springs)
Notice:
If you use acidic or corrosive cleaning products,
engine degreasers or aluminum cleaning agents on
fiberglass springs, you may damage the springs.
The repairs would not be covered by your warranty.
Use only approved cleaners when cleaning your
vehicle's fiberglass springs.
Chemical Paint Spotting
Some weather and atmospheric conditions can create a
chemical fallout. Airborne pollutants can fall upon and
attack painted surfaces on the vehicle. This damage
can take two forms: blotchy, ring-shaped discolorations,
and small, irregular dark spots etched into the paint
surface.
Although no defect in the paint job causes this, we 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.
Vehicle Identification
Vehicle Identification Number (VIN)
This legal identifier is in the front corner of the
instrument panel, on the driver side. It can be seen
through the windshield from outside. The VIN also
appears on the Vehicle Certification and Service
Parts labels and certificates of title and registration.
Engine Identification
The eighth character in the VIN is the engine code.
This code identifies the vehicle's engine, specifications,
and replacement parts. See “Engine Specifications”
under Capacities and Specifications
on page 6‑108for
the vehicle's engine code.

Maintenance Schedule
Introduction
Notice:Maintenance intervals, checks, inspections,
recommended fluids, and lubricants are necessary
to keep this vehicle in good working condition.
Damage caused by failure to follow scheduled
maintenance might not be covered by the vehicle
warranty.
Proper vehicle maintenance helps to keep the vehicle in
good working condition, improves fuel economy, and
reduces vehicle emissions for better air quality.
Because of all the different ways people use vehicles,
maintenance needs vary. The vehicle might need
more frequent checks and services. Please read the
information under Scheduled Maintenance. To keep the
vehicle in good condition, see your dealer/retailer.
The maintenance schedule is for vehicles that:
.carry passengers and cargo within recommended
limits on the Tire and Loading Information label.
See Loading the Vehicle on page 5‑28.
.are driven on reasonable road surfaces within legal
driving limits.
.use the recommended fuel. See Gasoline Octaneon page 6‑7.
{WARNING:
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, see your dealer/retailer to have a
qualified technician do the work. See Doing Your
Own Service Work on page 6‑5.
At your General Motors dealer/retailer, you can be
certain that you will receive the highest level of service
available. Your dealer/retailer has specially trained
service technicians, uses genuine GM replacement
parts, as well as, up to date tools and equipment to
ensure fast and accurate diagnostics.
The proper replacement parts, fluids, and lubricants to
use are listed in Recommended Fluids and Lubricants
on page 7‑10andMaintenance Replacement Partson
page 7‑12. We recommend the use of genuine parts
from your dealer/retailer.
