The headlight wiring is protected by a
circuit breaker in the fuseblock. 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 system checked right away.
To access the headlight circuit breaker,
squeeze the plastic clip together and
remove.
Windsheld 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 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.

Introduction
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 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 will find in the schedules
in this part.
So please read this part and note how you drive.
If you have
any questions on how to keep your vehicle in
good condition, see your Chevrolet 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.
260
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 or the removal
of
important components can significantly affect the quality of
the air we breathe. Improper fluid levels or even the wrong
tire inflation can increase the level
of emissions from your
vehicle.
To help protect our environment, and to help keep
your vehicle in
good condition, please maintain your vehicle
properly.

Downloaded from www.Manualslib.com manuals search engine How This Part is Organized
The remainder of this part is divided into five sections:
Section
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. You
will find a list of publications and how to get
them in this manual.
See the Index under Service
Publications.
Section B: Owner Checks & Services tells you what should
be checked whenever
you stop for fuel. It also explains what
you can easily do to help keep your vehicle
in good
condition.
Section
C: Periodic Maintenance Inspections explains
important inspections that your Chevrolet dealer’s service
department or another qualified service center should
perform.
Section
D: Recommended Fluids & 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.
Section
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 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.
