When lt3 Time for New Tires
K1656
One way to tell when it’s time for new tires is to check the treadwear
indicators, which will appear when your tires have only
2/32 inch (1.6 mm) or
less of tread remaining.
You need a new tire
if:
You can see the indicators at three places around the tire.
You can see cord or fabric showing through the tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep enough to show
The tire has a bump, bulge or split.
cord
or fabric.
The tire has a puncture, cut, or other damage that can’t be repaired
because of the size or location of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at the CertificationRire
label. The tires installed on your vehicle when
it was new had a Tire
Performance Criteria Specification (TPC Spec) number on each t\
ire’s sidewall.
When you get new tires, get ones with that same TPC Spec num\
ber. That
way, your vehicle will continue to have tires that are designed to give proper
endurance, handling, speed rating, traction, ride and other thin\
gs during normal service on your vehicle. If your tires have an all-season tread design,
the
TPC number will be followed by a “MS” (for mud and snow).

Glass
Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or
a liquid household glass cleaner will remove normal tobacco smo\
ke and dust
films.
Don’t use abrasive cleaners on glass, because they may cause\
scratches.
Avoid placing decals on the inside rear window, since they may\
have to be
scraped
off later.
If abrasive cleaners are used on the inside of the rear window, \
an electric
defogger element may be damaged. Any temporary license should n\
ot be
attached across the defogger grid.
Cleaning the Outside of fhe Windshield, Backglass and Wiper
Blades
If the windshield is not clear after using the windshield washer, or if the wiper
blade chatters when running, wax or other material may be on the blade or
windshield.
Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami
Powder@
(GM Part No. 1050011). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced\
when worn.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm
or cold water.
Don’t wash your vehicle in the direct rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (non\
-detergent)
soaps. Don’t use cleaning agents that contain acid
or abrasives. All cleaning
agents should be flushed promptly and not allowed to dry on t\
he surface,
or
they could stain. Dry the finish with a soft, clean chamois or a 100% cotton
towel
to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water
to enter your vehicle.
Finish Care
Occasional waxing or mild polishing of your vehicle may be necessary to
remove residue from the paint finish. You can get
GM approved cleaning
products from your dealer. (See “Appearance Care and Materia\
ls” in the Index.)

Your VIN.
Its model designation.
Paint information.
A list of all production options and special equipment.
Be sure that this label is not removed from the vehicle.

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 link\
s in the wiring
itself. This greatly reduces the chance of fires caused by electrical problems.
See “Fuses and Circuit Breakers” in the Index for more i\
nformation.

Downloaded from www.Manualslib.com manuals search engine Headlights
The headlight wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights
to go on and off, or in some cases to
remain
off. If this happens, have your headlight 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 s\
top until the
motor cools. If the overload is caused by some electrical prob\
lem and not
snow, etc., be sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power windows a\
nd other power
accessories. When the current load is too heavy, the circuit b\
reaker opens
and closes, protecting the circuit until the problem is fixed
or goes away.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by \
an in-line fuse
in the battery feed wire. This fuse is near the junction bloc\
k. See “Trailer
Wiring Harness” in the Index.
Fuse Block
K3629
The fuse block is under the instrument panel on the driver’\
s side. You can
remove the cover with
a screwdriver and then remove fuses with a fuse
extractor. To remove fuses
if you don’t have one, hold the end of the fuse
between your thumb and index finger and pull straight out.

Be sure to use the correct fuse. If you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one of the correct value. Just pick

A Word About Maintenance
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 lo\
ng 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 GM vehicles, maintenance
needs vary. You may even need more frequent checks and replacements than
you will find in the schedules in this section.
So please read this section and
note how you drive. If you have any questions on how
to keep your vehicle
in good condition, see your GM dealer, the place many
GM owners choose
to have their maintenance work done. Your dealer can be relied upon to use
proper parts and practices.
Your Vehicle And The Environment
Proper vehicle maintenance not only helps keep your vehicle in good working
condition, but it also helps the environment.
All recommended maintenance
procedures are important. Improper vehicle maintenance or the re\
moval of
important components can significantly affect the quality of the air we breathe.
Improper fluid levels or even the wrong tire inflation can inc\
rease the level of
emissions from your vehicle. To help protect our environment, and to help
keep your vehicle in good condition, please maintain your vehic\
le properly.
CAUTION
. Performing maintenance work on a vehicle can be dangerous. ...
trying to do some jobs, you can be seriously injured. Do your own
maintenance work only
if you have the reauired know-how and the
proper
tools and equipment for the iob. IOU have ar doubt. have
a qualified technician do the
WOrK. I
If you are skilled enough to do some work on your vehicle, you will probably
want
to get the service information GM publishes. You will find a list of
publications and how to get them in Section
8, “Customer Assistance
Information”. See “Service Publications’’ in the Index.
The Maintenance Record provides a place for you to record the maintenance
performed on your vehicle. Whenever any maintenance is performed, be sure
to write
it down in this section. This will help you determine when your next
maintenance should be done. In addition,
it is a good idea to keep your
maintenance receipts. They may be needed to qualify your vehicle for
warranty repairs.
