Downloaded from www.Manualslib.com manuals search engine Glass
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.
von’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.
Cleaning the Outside of the Windshield and
Wiper Blades
If the windshield is not clear after using the windshield washer, or \
if the
wiper blade chatters when running, wax or other material may b\
e on the
blade or windshield.
Clean the outside
of the windshield with GM Windshield Cleaner, Bon-Ami
Powder@ (GM Part
No. 1050011). The windshield is clean if beads do not
form when you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
windshield washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced\
when worn.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm or cold water.
Don’t wash your vehicle
in the direct rays of the sun. Don’t use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (\
mild
detergent) soaps. Don’t use cleaning agents that contain aci\
d or abrasives.
All cleaning agents should be flushed promptly and not allowed \
to dry on
the surface, or they could stain. Dry the finish with a soft,\
clean chamois or
a
100% cotton towel to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water to enter your vehicle.

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, or in some cases to
remain
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.

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’pWple use their GM vehicle\
s, 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 up\
on 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 infla\
tion 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
