Mixing tires could cause you to lose control while
driving.
If you mix tires of different sizes or types
(radial and bias-belted tires), the vehicle may not
handle properly, and you could have
a crash.
Using tires
of different sizes may also cause
damage to
your vehicle. Be sure to use the same
size and type tires
on all wheels.
It’s all right to drive with your compact spare
(if you have one). It was developed for
use on
your vehicle.
Uniform Tire Quality Grading
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
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
c Urades, they rnust also conform to Federal safety
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
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 clilnate.

Mix Multi-Purpose Powdered Cleaner following the
directions on the container label.
Use suds only and apply with a clean sponge. Don't
saturate the material and don't
rub it roughly.
As soon as you've cleaned the section, use a sponge
to remove the suds.
Rinse the section with a clean, wet sponge.
Wipe
off what's left with a slightly damp paper towel
or cloth.
Dry
it immediately with a blow dryer.

Some spots and stains
will clean off better with just
water and mild soap.

Gently scrape excess soil from the trim material with
a clean, dull knife or scraper.
Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the
outside
of the stain, "feathering" toward the center.
Keep changing to
a clean section of the cloth.
When you clean a stain from fabric, immediately
dry the area
with a blow dryer to help prevent a
cleaning ring.

Fabric Protection Non-Greasy Stains
Your vehicle has upholstery and carpet that has been
treated with Scotchgard" Fabric Protector,
a 3M
product. It protects fabrics by repelling oil and water,
which are the carriers of most stains. Even
with this
protection, you still need

carpet often to keep
it looking new.
Further information on cleaning
is available by calling
1-800-433-3296 (in Minnesota, 1-800-642-6 167).
Special Cleaning Problems

polish, coffee with cream, chewing
gum, cosmetic
creams, vegetable
oils, wax crayon, tar and asphalt can
be removed as follows:
1. Carefully scrape off excess stain.
2. Follow the solvent-type instructions
described earlier.
Shoe polish, wax crayon,
tar and asphalt will stain if left
on
;1 vehicle's seat fabric. They should be removed as
soon as possible. Be careful, because the cleaner will
dissolve them and may cause them to spread. Stains caused

Headlamps
The headlamp wiring is protected by an internal 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 circuit breaker
and a fuse.
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, be sure
to get it fixed.
Power Windows and Other Power Options
Circuit breakers protect the power windows 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.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by
a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance of fires 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 fuse block is at the
driver's end of the
instrument panel.
Remove the
toller by turning the fastener
counterclockwise. Extra fuses and the fuse extractor are
provided
in the cover. To reinstall the fuse panel cover.
push in and turn the fastener clockwise.
