Downloaded from www.Manualslib.com manuals search engine Care of Safety Belts
Keep belts clean and dry.
A CAUTIOl.,
Do not bleach or dye safety belts. If you do, it
may severely weaken them.
In a crash, they
might not be able to provide adequate protection. Clean safety belts only with mild soap and
lukewarm water.
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.
Don’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.
If abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
Cleaning the Outside of the Windshield,
Batklass 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 be on the blade or windshield.
Clean the outside
of the windshield with GM
Windshield Cleaner, Bon-Ami Powder@’ (GM Part
No. 105001 1). 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.
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,)

Add-on Electrical Equipment
NOTICE:
Don’t add anyth’ing 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.
Headlamps
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps
to flicker on and off, or in some cases to remain
off. If this happens, have your headlamp 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.
Although the’circuit is protected from electrical
overload, overload due to heavy snow, etc., may cause
wiper linkage damage. Always clear ice and heavy snow
from the
the windshield before using the windshield
wipers. If the overload is caused by some electrical
problem and not
snow, etc., be sure to get it fixed.

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 en-ands 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:

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:
Gasoline engine vehicles and diesel engine vehicles
have different maintenance requirements.
If you have a
diesel engine, follow a schedule designated for diesel
engine vehicles only.
See the Diesel Engine Supplement for diesel engine
maintenance schedules.
