Downloaded from www.Manualslib.com manuals search engine Cleanjng 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. 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 worn blades.
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.)
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth
of color, gloss retention and durability.

Downloaded from www.Manualslib.com manuals search engine Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. It appears on
a plate
in the front corner of the instrument panel, on the
driver’s side. You can
see it if you look through the
windshield from outside your vehicle. The VTN also
appears
on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement
parts.
Service Parts Identification Label
You’ll find this label on the inside of the front storage
compartment door. It’s very helpful if you ever need to
order parts. On this label
is:
your VIN,
the model designation,
0 paint information and
0 a list of all production options and
special equipment.
Be sure that this label is not removed from the vehicle.
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 “Servicing
Your
Air Bag-Equipped Vehicle’’ in the Index.

Downloaded from www.Manualslib.com manuals search engine Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. 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 Wiper Fuses
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 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 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.
Spare fuses and a fuse puller are located in the
underhood electrical center. You can remove fuses with
the fuse puller. Remember to replace
any of the spare
fuses
you use, so you will have some if you ever need
them again.
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.
There are two fuse blocks in your vehicle: one is inside
the vehicle and one is
in the engine compartment.

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 dealership’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 dealership’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:
0 carry passengers and cargo within recommended
limits. You will find these limits
on your vehicle’s
Certificationmire label. See “Loading Your Vehicle’’
in the Index.
are driven on reasonable road surfaces within legal
driving limits.
0 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:
