(SERVICE ENGINE SOON )
This light on your instrument cluster 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.
Loading Your Vehicle
The Certificationire
label is found on the
rear edge of the
driver’s door. 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 CertificatiodTire 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 Gross Axle Weight Rating
(GAWR) for either the front or rear axle.

Downloaded from www.Manualslib.com manuals search engine Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only with new
GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel nuts
for your
GM model.
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.

NOTICE:
Be careful with a hair dryer or heat lamp. You could scorch the
fabric.
0 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.)

Your vehicle has upholstery that has been treated with Scotchgard" Fabric
Protector, a 3M product. Scotchgard" 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 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.
0 Follow the solvent-type instructions described earlier.
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 causf
1 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.
If a stain remains, follow the foam-type instructions described earlier.
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 1 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.
If a stain remains, clean it with solvent-type cleaner.

Downloaded from www.Manualslib.com manuals search engine 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 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 or goes
away.
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.

The fuse block is
under the instrument
panel
on the driver’s
side. Remove the
cover with
a
screwdriver.
To remove fuses if you don’t have a fuse extractor, 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 this section.
