Downloaded from www.Manualslib.com manuals search engine 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 reflections in
the windshield
and even make it difficult
to see through the windshield
under certain conditions.
Care of Safety Belts
Keep belts clean and dry.
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash, they
might not be able to provide adequate protection.
Clean safety belts only with mild
soap and
lukewarm water.
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, wax,
sap or other material may be on the blade or windshield.
Clean the outside of the windshield with
GM
Windshield Cleaner, Bon Ami@ Powder (non-scratching
glass cleaning powder),
GM Part No. 105001 1 or
equivalent. 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.
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.

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 “Servicing
Your Air Bag-Equipped Vehicle” in the Index.
Headlamps
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to flicker 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.
Although the circuit is protected from electrical
overload, overload due to heavy snow, etc., may cause
wiper linkage damage. Always clear ice and heavy snow
from the the windshield before using the windshield
wipers. If the overload is caused by some electrical
problem and not snow, etc., be sure to get it fixed.

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.
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. If you
go
to your dealer for your service needs, you’ll know
that GM-trained and supported service people will
perform the work using genuine GM parts.
The proper fluids and lubricants to use are listed in Part D.
Make sure whoever services your vehicle uses these. All parts should be replaced and all necessary repairs done
before you
or anyone else drives the vehicle.
These schedules are for vehicles that:

limits. You will find these limits on your vehicle’s

are driven on reasonable road surfaces within legal
driving limits.
are driven off-road in the recommended manner. See
“Off-Road Driving With Your Four- Wheel-Drive
Vehicle” in the Index.
use the recommended fuel. See “Fuel” in the Index.
Selecting the Right Schedule
First you’ll need to decide which of the two schedules is
right for your vehicle. Here’s how to decide which
schedule
to follow:
Gasoline engine vehicles and diesel engine vehicles
have different maintenance requirements. If you have a
diesel engine, follow a schedule designated for diesel
engine vehicles only.
See the Diesel Engine Supplement for diesel engine
maintenance schedules.

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, kingpin bushings,
steering linkage, transmission shift linkage, transfer case
shift linkage, parking brake cable guides, front axle
propshaft splines and brake pedal springs. Ball joints and kingpin bushings should not
be lubricated unless
their temperature
is 10” F (- 12” C) or higher, or they
could be damaged.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under “Periodic
Maintenance Inspection” in Part
C of this schedule.

Lubricants” in the Index for proper lubricant to use):
