Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
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.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a speci®ed government test course.
For example, a tire graded 150 would wear one and
a half (1.5) 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 signi®cantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction ± AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire's ability
to stop on wet pavement as measured under controlled
conditions on speci®ed 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 straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.

Here are some cleaning tips:
·Always read the instructions on the cleaner label.
·Clean up stains as soon as you can ± before
they set.
·Carefully scrape off any excess stain.
·Use a clean cloth or sponge, and change to a clean
area often. A soft brush may be used if stains are
stubborn.
·If a ring forms on fabric after spot cleaning, clean
the entire area immediately or it will set.
Cleaning Coated Moldings
These moldings are around the hatch opening in the
rear area.
·When lightly soiled, wipe with a sponge or soft
lint-free cloth dampened with water.
·When heavily soiled, use warm soapy water.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or
saddle soap and wipe dry with a soft cloth. Then, let
the leather dry naturally. Do not use heat to dry.
·For stubborn stains, use a leather cleaner.
·Neveruse oils, varnishes, solvent-based or abrasive
cleaners, furniture polish or shoe polish on leather.
·Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the ®nish,
it can harm the leather.
Cleaning the Top of the Instrument
Panel
Use only mild soap and water to clean the top surfaces
of the instrument panel. Sprays containing silicones
or waxes may cause annoying re¯ections in the
windshield and even make it difficult to see through the
windshield under certain conditions.
5-76

Cleaning the Convertible Top
Your convertible top should be cleaned often. If you use
an automatic car wash, use one with water jets and
hanging cloths. 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. Don't 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. Your dealer has a Convertible
Top Cleaner and Water Repellent. 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.
·Don't get any cleaner on the vehicle's painted
®nish; it could leave streaks.
·If you decide to go through an automatic car wash,
ask the manager if the equipment could damage
your top.
Cleaning Aluminum Wheels
Keep your 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.
The surface of these wheels is similar to the painted
surface of your vehicle. Don't use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because you could damage the surface. Do not
use chrome polish on aluminum wheels.
Don't take your vehicle through an automatic car wash
that has silicone carbide tire cleaning brushes. These
brushes can also damage the surface of these wheels.
Cleaning Tires
To clean your tires, use a stiff brush with tire cleaner.
Notice:When applying a tire dressing, always take
care to wipe off any overspray or splash from all
painted surfaces on the body or wheels of the
vehicle. Petroleum-based products may damage the
paint ®nish and tires.

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 ®res caused by electrical problems.
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 identical
size and rating.
If you ever have a problem on the road and don't have
a spare fuse, you can borrow one that has the same
amperage. 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 correct
amperage. Replace it as soon as you can.
Instrument Panel Fuse Block
The instrument panel fuse
block is located on the
passenger's side of
the vehicle, under the
instrument panel and
under the toe-board.
Remove the carpet and toe-board covering to access
the fuse block by pulling at the top of each corner of the
panel. Then turn the fuse block door knob
counterclockwise and pull the door to access the fuses.

At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and all your
belts, buckles, latch plates, retractors and anchorages
are working properly. Look for any other loose or
damaged safety belt system parts. If you see anything
that might keep a safety belt system from doing its
job, have it repaired. Have any torn or frayed safety belts
replaced.
Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged or that
streak or miss areas of the windshield. Also see
Cleaning the Outside of Your Vehicle on page 5-78.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page 6-14.
Manual Transmission Check
Check the transmission ¯uid level; add if needed. SeeManual Transmission Fluid on page 5-20. Check
for leaks. A ¯uid leak is the only reason for ¯uid loss.
Have the system inspected and repaired if needed.
Automatic Transmission Check
It is not necessary to check the transmission ¯uid level.
A transmission ¯uid leak is the only reason for ¯uid
loss. Check for leaks. If a leak occurs, take the vehicle
to your dealer and have it repaired as soon as
possible.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
speci®ed in Part D.
Body Lubrication Service
Lubricate all body door hinges. Also lubricate all hinges
and latches, including those for the hood, rear
compartment, console door and any folding seat
hardware. Part D tells you what to use. More frequent
lubrication may be required when exposed to a corrosive
environment.
