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.
The headlight wiring is protected by
a circuit breaker in the light switch. An
electrical overload
will cause the lights to flicker 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. 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 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.

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.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
Engine misfiring
Loss of performance
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter (gas engines)
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Three- Way Catalytic Converter (diesel engines)
Your vehicle’s three-way catalytic converter is designed to reduce the
particulates in your vehicle’s exhaust. If your vehicle’s three-way catalytic
converter ever needs to be replaced, it must be replaced with a three-way
catalytic converter intended for use with diesel engines only.

vehicles and diesel engine vehicles below
8,500 lbs. GVWR)
Gasoline Engines

air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle. If
you use leaded fuel, you could damage your oxygen sensor
(02) and
three-way catalytic converter.
Diesel Vehicles Below S,5UU LBS. GVWR
This system monitors engine speed and throttle position. It adjusts exhaust
gas recirculation to limit emissions.

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 Injection 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.

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 Certificatioflire 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.

Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts, and wheel nuts should be replaced.
If
the wheel leaks air, replace it (except some aluminum wheels, which can
sometimes be repaired). See your GM dealer if any
of these conditions exist.
Your dealer will know the kind
of wheel you need.
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.

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

air hose, hair dryer, or heat lamp to help prevent a cleaning ring. (See
