Add-on Lxtrical 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.
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 in the
wiring itself. This greatly reduces the chance of fires caused by electrical
problems.

Downloaded from www.Manualslib.com manuals search engine Headlights
The headlight wiring is protected by a circuit breaker in the light switch. An
electrical overload will cause the lights to go on and off. If this happens,
have your headlight 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 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.
Trailer Wiring Harness
The optional seven-wire trailer wiring harness is protected by an in-line
fuse in the battery feed wire. This fuse is near the junction block. See
“Trailer Wiring Harness” in the
Features & Controls section.
Fuse Block
The fuse block is in
the instrument panel
on the driver’s side.
Remove the cover
with a screwdriver and
then you
can remove
fuses with a fuse
extractor.

Downloaded from www.Manualslib.com manuals search engine 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 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, the place many GM owners choose
to have their maintenance work done. Your dealer can be relied upon
to use
proper parts and practices.
Your Vehicle And The Environment
Proper vehicle maintenance not only helps keep your vehicle in good
working condition, but it 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.
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 Section
8, Customer Assistance
Information.
See “Service Publications” in the Index.
The 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.

Below are explanations of the services listed in the maintenance charts.

To determine the preferred viscosity oil for your
vehicle’s engine (e.g. SAE

joint, steering linkage, and transfer case shift linkage, parking brake
cable guides, propshaft splines, universal joints, brake pedal springs,
and clutch pedal springs at the intervals specified on the proper
maintenance schedule, or at every engine oil change, whichever comes
first.
Ball joints should
not be lubricated unless their temperature is 10°F
(-12°C) or higher. When the weather is cold, let them warm up before
lubricating them
or they could be damaged.
Also, be sure to check all the vehicle fluid levels at this time.
COOLING SYSTEM SERVICE* - Drain, flush and refill the
system with new or approved recycled coolant conforming to “GM
Specification
603%”’. See “Engine Coolant” in the Index for the
proper coolant and mixture to use in your vehicle.

deteriorated. Clean the outside of the radiator and air conditioning
condenser. Wash the radiator neck. To ensure proper operation,
pressure test the radiator and cap.
