6-51 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 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
-- 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 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 straight
-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.

Special Care for Canvas Top and
Plastic Windows
Your canvas 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. Thoroughly rinse the entire vehicle,
then let the top dry in direct sunlight.
To protect the canvas top:
After you wash the vehicle, make sure the top is
completely dry before you open or remove it.
Don't get any vinyl 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.
The plastic windows are pliable and can be scratched if
you don't take these precautions when you clean them:
Wipe off dust with a soft cotton cloth moistened with
clean, cool or lukewarm water. Don't use a ªdryº
cloth. Wipe in one direction only, not back and forth.
To remove frost, snow or ice, use lukewarm water.
Don't use a scraper or any de
-icing fluids.
Wash the windows with a soft cloth and clean, cool
or lukewarm water. Never use a dry cloth, hot water,
strong soap or detergent, solvents or harsh cleaning
agents. Rinse thoroughly and wipe with a slightly
moist soft, clean cloth.
Don't put any labels, stickers or tape on windows.
It's hard to remove adhesives left on the window
when such items are removed. If a sticker or label
must be removed, remove any adhesive left on the
window while the adhesive is still soft and sticky.
Press on a new sticker or piece of tape and then lift it
off again; keep doing this until all the adhesive lifts
off with the sticker or tape.

Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
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 vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by fuses, circuit breakers and thermal links
in the wiring itself. This greatly reduces the chance of
fires caused by electrical problems.
Look at the copper
-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 correct size.
If you ever have a problem on the road and don't have a
spare fuse, you can borrow one. 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
size you need. Replace it as soon as you can.
Before replacing a fuse, turn every vehicle electrical
switch off.
There are two fuse blocks in your vehicle: the
instrument panel fuse block and the engine compartment
fuse block.

6-66 Instrument Panel Fuse Block
This fuse box is located under the driver's side of the
instrument panel. The fuses here protect each separate
circuit including headlamps. There are spare fuses inside
the fuse box. If you have electrical failure, check
here first.

7-45 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 ªWiper Blades,
Cleaningº in the Index.
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 ªRecommended Fluids and Lubricantsº in
the Index.Fluid Level Check
Check the transfer case, axle differential(s) and
automatic or manual transmission fluid levels and add as
needed. See ªTransfer Case,º ªAxle, Rear,º ªAxle,
Frontº and ªAutomatic Transmissionº or ªManual
Transmissionº in the Index. Check for leaks. A fluid loss
in these systems could indicate a problem. Have the
system inspected and repaired at once.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified in Part D.
Body Lubrication Service
Lubricate all body door hinges. Also lubricate all hinges
and latches, including those for the hood, rear
compartment, glove box door, 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.
