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. See “Fuses and Circuit Breakers” in the Index for more
information.
Headlights
The headlight wiring is protected by a circuit breaker in the \
light switch. An
electrical overload will cause the lights to flicker on and of\
f, 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. 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.
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. This protects the circuit until the current \
load returns to
normal or 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 Index for more information.
Fuse Block
The fuse block is
behind an access door
at the bottom of the
instrument panel,
next
to the parking brake
release lever.
To remove fuses if you don’t have one, hold the end of the fuse between
your thumb and index finger and pull straight out.
Be, sure to use the correct fuse.
If you ever have a problem on the road and
don’t have a spare fuse, you can “borrow” one of the correct value. Just pick
some feature
of your vehicle that you can get along without-like the radio
or cigarette lighter--and use
its fuse, if it is of the value you need. Replace
it as soon as you can. See “Fuses and Circuit Breakers“ in the Index for
more information.

Malfunction Indicator
(SERVICE ENGINE SOON) Lamp
The Malfunction Indicator (SERVICE ENGINE SOON) Lamp on your
instrument panel lets you know when
your emission system needs service.
The light
will come on briefly when you start your engine to let you know
that the system is working. If
it does not come on when you start your
engine,
or if it comes on and stays on while you’re driving, your system
may need service. Your vehicle should still be driveable, but
you should
have your system serviced right away.
Secondary Air hjection Reaction (AIR) System
You may have this system. It has a control valve that will direct air to where
it is needed. If the AIR system needs service, your Malfunction Indicator
(SERVICE ENGINE SOON) Lamp on your instrument panel will come on.

The Certification/Tire
label is found on the
rear edge of the
driver’s door or
in the
Incomplete Vehicle
Document
in the cab.
The label shows
the size of your original tires and the inflation pressures
needed to obtain the gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of
the vehicle, all occupants, fuel and cargo.
The Certification/Tire label also tells
you the maximum weights for the
front and rear axles, called Gross Axle Weight Rating (GAWR). To find out
the actual loads on your front and rear axles, you need to go to a weigh
station and weigh your vehicle. Your dealer can help you
with this. Be sure
to spread out your load equally
on both sides of the centerline.
Never exceed the GVWR for your vehicle, or
the GAWR for either the front
or rear axle.
And,
if you do have a heavy load, you should spread it out.

NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim,
bumper height, vehicle ground clearance, and tire or tire chain
clearance to the body and chassis.
Used Replacement Wheels
Tire Chains
NOTICE:
If your vehicle has dual wheels or LT26Y75R16 size tires, don’t
use tire chains; they can damage your vehicle.
If you don’t have
dual wheels or
if you have a tire size other than LT265/75R16,
use tire chains only where legal and only when you must. Use
only SAE Class “S” type chains that are the proper size for your
tires. Install them on the tires of the rear axle. Tighten them as
tightly
as possible with the ends securely fastened. Drive slowly
and follow the chain manufacturer’s instructions.
If you can
hear the chains contacting your vehicle, stop and retighten them.
If the contact continues, slow down until it stops. Driving too
fast with chains on will damage your vehicle.

Cleaning the Inside of Your Vehicle
Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or
leather with
a clean, damp cloth.
Your GM dealer has two
GM cleaners, a solvent-type spot lifter and a
foam-type powdered cleaner. They will clean normal spots and stains very
well.
Do not use them on vinyl or leather.
Here are some cleaning tips:
Always read the instructions on the cleaner label.
0 Clean up stains as soon as you can - before they set.
Use a clean cloth or sponge, and change to a clean area often. A soft
brush may be used if stains are stubborn.
Use solvent-type cleaners in a well-ventilated area only. If you use
them, don’t saturate the stained area.
0 If a ring forms after spot cleaning, clean the entire area immediately or
it will
set.
Using Foam-Type CIeaner on Fabric
0 Vacuum and brush the area to remove any loose dirt.
Always clean a whole trim panel or section. Mask surrounding trim
Mix Multi-Purpose Powdered Cleaner following the directions on the
along
stitch or welt
lines.
container label.
Use suds only and apply with a clean sponge.
Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge to remove the
suds.
Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel or cloth.
Then dry it immediately with a blow dryer or a heat lamp.
I NOTICE:
I Be careful with a hair dryer or heat lamp. You could scorch the I
fabric.
Wipe with a clean cloth.

Using Solvent-Type Cleaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean off better
with just water and mild soap.
If you need to use a solvent:
0 Gently scrape excess soil from the trim material with a clean, dull knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the outside
of the
stain, “feathering” toward the center. Keep changing to
a clean section
of the cloth.
0 When you clean a stain from fabric, immediately dry the area with an
air hose, hair dryer, or heat lamp
to help prevent a cleaning ring. (See
the previous NOTICE.)
Fabric Protection
Your vehicle has upholstery and trim carpet that has been treated with
Scotchgard
TM Fabric Protector, a 3M product. Scotchgard TM protects fabrics
by repelling oil and water, which are the carriers of most stains. Even with
this protection, you still need to clean your upholstery and trim carpet often
to keep
it looking new.
Further information on cleaning is available by calling 1-800-433-3296
(in Minnesota, 1-800-642-6 167).
Special Cleaning Problems
Greasy or Oily Stains
Such as grease, oil, butter, margarine, shoe polish, coffee with cream,
chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt.
0 Carefully scrape off excess stain.
Follow the solvent-type instructions described earlier.
0 Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon as possible. Be careful,
because
the cleaner will dissolve them and may cause them to spread.
Non-Greasy Stains
Such as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine,
vomit, urine and blood.
Carefully scrape off excess stain, then sponge the soiled area with cool
water.
0 If a stain remains, follow the foam-type instructions described earlier.

ProCarManuals.com

0 If an odor lingers after cleaning vomit or urine, treat the area with a
waterhaking soda solution: 1 teaspoon (5 ml) of baking soda to I cup
(250 ml) of lukewarm water.
0 If needed, clean lightly with solvent-type cleaner.
Combination Stains
Such as candy, ice cream, mayonnaise, chili sauce and unknown stains.
Carefully scrape off excess stain, then clean with cool water and allow
to dry.
0 If a stain remains, clean it with solvent-type cleaner.
Cleaning Vinyl
Use warm water and a clean cloth.
Rub with a clean, damp cloth to remove dirt. You may have to do it
more than once.
0 Things like tar, asphalt and shoe polish will stain if you don’t get them
off quickly. Use a clean cloth and a solvent-type vinyl cleaner.
Cleaning Leather
Use a soft cloth with lukewarm water and a mild soap or saddle soap.
For stubborn stains, use a mild solution of 10% isopropyl alcohol
(rubbing alcohol) and
90% water.
Never use oils, varnishes, solvent-based or abrasive cleaners, furniture
polish or shoe polish on leather.
Soiled leather should be cleaned immediately. If dirt is allowed to work
into finish,
it can harm the leather.
Cleaning the Top of the Instrument Panel
Use only mild soap and water to clean the top surfaces of the instrument
panel. Sprays containing silicones or waxes may cause annoying reflections
in the windshield and even make
it difficult to see through the windshield
under certain conditions.
