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.

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, have
it fixed.

Power Windows

A circuit breaker in the fuse panel protects the power
windows. When the current load is too heavy, the circuit
breaker opens and closes, protecting the circuit until the
problem is fixed.

Fuses and Circuit Breakers

The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible links. This greatly reduces the chance of
damage 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 to
replace a bad fuse with a new one of the identical size
and rating.

There are three fuse blocks in your vehicle: two
instrument panel fuse blocks and the engine
compartment fuse block.

Instrument Panel Fuse Blocks

There are two fuse panels for your vehicle. One is
located on the driver’s side of the instrument panel and
the other is located on the passenger’s side.

Have you purchased the GM Protection Plan? The Plan
supplements your new vehicle warranties. See your
Warranty and Owner Assistance booklet or your 
dealer for details. 

Introduction

Your Vehicle and the Environment

Proper vehicle maintenance not only helps to keep your
vehicle in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance can even
affect the quality of the air we breathe. Improper fluid
levels or the wrong tire inflation can increase the level
of emissions from your vehicle. To help protect our
environment, and to keep your vehicle in good
condition, please maintain your vehicle properly.

Maintenance Requirements

Maintenance intervals, checks, inspections and
recommended fluids and lubricants as prescribed in this
manual are necessary to keep your vehicle in good
working condition. Any damage caused by failure to
follow recommended maintenance may not be covered
by warranty.

7-3

How This Section is Organized

This maintenance schedule is divided into five parts:

“Part A: Scheduled Maintenance Services” explains
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.

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 want to get the service information, 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 dealer’s service
department or another qualified service center 
should perform.

“Part D: Recommended Fluids and Lubricants” lists
some recommended products necessary 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” is a place for you 
to record and keep track of the maintenance performed
on your vehicle. Keep your maintenance receipts. 
They may be needed to qualify your vehicle for
warranty repairs.

7-4

Part A: Scheduled 
Maintenance 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
vehicles, maintenance needs vary. You may need more
frequent checks and replacements. So please read the
following and note how you drive. If you have any
questions on how to keep your vehicle in good
condition, see your 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.

This schedule is for vehicles that:
D carry passengers and cargo within recommended

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

-

Loading Information label. See “Loading 

Your Vehicle” in the Index.

D are driven on reasonable road surfaces within legal

driving limits.

D use the recommended fuel. See “Fuel” in the Index.

Scheduled Maintenance

7-5

The services shown in this schedule up to 100,000 miles
(166 000 km) should be repeated after 100,000 miles
(166 000 km) at the same intervals for the life of 
this vehicle. The services shown at 150,000 miles 
(240 000 km) should be repeated at the same interval
after 150,000 miles (240 000 km) for the life of 
this vehicle.

See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.

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.

+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection” under
“Periodic Maintenance Inspections” in Part C 
of this schedule.

Scheduled Maintenance

7-6

Engine Oil Scheduled Maintenance

Change engine oil and filter as indicated by the 
GM Oil Life System

t (or every 12 months,

whichever occurs first). Reset the system.

Your vehicle has a computer system that lets you know
when to change the engine oil and filter. This is based on
engine revolutions and engine temperature, and not on
mileage. Based on driving conditions, the mileage at
which an oil change will be indicated can vary
considerably. For the oil life system to work properly,
you must reset the system every time the oil is changed.

When the system has calculated that oil life has 
been diminished, it will indicate that an oil change is
necessary. A CHANGE OIL light will come on. Change
your oil as soon as possible within the next two times
you stop for fuel. It is possible that, if you are driving
under the best conditions, the oil life system may not
indicate that an oil change is necessary for over a year.
However, your engine oil and filter must be changed at
least once a year and at this time the system must be
reset. It is also important to check your oil regularly and
keep it at the proper level.

If the system is ever reset accidentally, you must change
your oil at 3,000 miles (5 000 km) since your last oil
change. Remember to reset the oil life system whenever
the oil is changed. See “Oil Life System” in the Index
for information on resetting the system.
