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
1 /16 inch ( 1.6 mm) or
less
of tread remaining.
You need
a new tire if any of the following statements
are true:
You can see the indicators at three or more places
around
the tire.
0 You can see cord or fabric showing through the
tire's rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough to
show cord or fabric.
0 The tire has a bump, bulge or split.
The tire has a puncture, cut or other damage that
can't be repaired well 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 CertificatiodTire label.
The tires installed on your vehicle when
it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire's sidewall. When
you get new tires.
your vehicle
will continue to have tires that are designed
to give proper endurance. handling, speed rating,
traction. ride and other things during
normal service on
your vehicle. If your tires have an all-season tread
design, the
TPC number will be followed by an "MS"
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial)
as your original tires.
t oet ones with that same TPC Spec number. That way

Glass should be cleaned often. GM Glass Cleaner (GM
Part No. 1050427) or a liquid household glass cleaner
will
remove normal tobacco smoke and dust films on
interior glass.
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 not be attached across
the
defogger grid.
Cleaning the Outside of the
Windshield, Backglass
and
Wiper Blades
If the windshield is not clear after using the windshield
washer.
or if the wiper blade chatters when running,

or windshicld. Clean
the outside of the windshield with
GM
Windshield Cleaner, Bon Ami@ Powder (non-scratching
glass cleaning powder), GM Part
No. 10500 11. The
windshield is clean if beads do not form when
you rinse
it with water.
Grime from
the windshield will stick to the wiper blades
and affect their performance. Clean the blade by wiping
vigorously with
a cloth soaked in full-strength
windshield washer solvent. Then rinse the blade
with water.
Check
the wiper blades and clean them as necessary;
replace blades that
look worn.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with
a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. (See “Recommended
Fluids and Lubricants” in the Index.)

Downloaded from www.Manualslib.com manuals search engine 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 cover 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.

Downloaded from www.Manualslib.com manuals search engine How This Section is Organized
The remainder of this section is divided into five parts:
“Part
A: Scheduled Maintenance Services” shows
what
to have done and how often. Some of these
services can be complex,
so unless you are technically
qualified and have the necessary equipment,
you should
let your dealer’s service department or another qualified
service center do these jobs.
A CAUTION:
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, have a qualified
technician do the work.
If you are skilled enough to do some work on your
vehicle, you will probably want to get the service
information
GM publishes. See “Service and Owner
Publications”
in the Index. “Part
B: Owner Checks and Services”
tells you
what should be checked and when. It also explains
what you can easily do
to help keep your vehicle in
good condition.
“Part C: Periodic Maintenance Inspections”
explains important inspections that your
GM dealer’s
service department or another qualified service center
should perform.
“Part
D: Recommended Fluids and Lubricants” lists
some products
GM recommends to help keep your
vehicle properly maintained. These products, or their
equivalents, should be used whether
you do the work
yourself or have
it done.
“Part
E: 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 part. 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.

Services
Using Your Maintenance Schedule
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
long 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'll 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.
This part tells
you the maintenance services you should
have done and when you should schedule them.

The services shown in this schedule up to 100,000 miles
( 166 000 km) should be performed after 100,000 miles
(166 000 km) at the same intervals. The services shown
at
150,000 miles (240 000 km) should be performed at

Footnotes
? The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that
the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior
to the
completion of the vehicle’s
useful life. We, however,
urge that all recommended maintenance services
be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the front suspension, ball joints, steering
linkage and transfer case shift linkage, parking brake
