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 wirin\
g
itself. This greatly reduces the chance
of fires caused by electrical problems.
See “Fuses and Circuit Breakers” in the Index for more information.
to use a magnetic screwdriver when installing the screws.
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.

Service & Appearance Care
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 for more information.

The fuse block is in
the instrument panel on the driver’s side.
You can remove fuses with a fuse extractor, if you have one. 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.

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
Your vehicle’s three-way catalytic converter is designed to reduce the
pollutants in your vehicle’s exhaust. Use only unleaded fuel in your vehic\
le. If
you use leaded fuel, you could damage your three-way catalytic \
converter,
and other engine components.
Computer Command Control System
This system has an oxygen (OS) sensor that helps keep your engine’s
air-fuel mixture at a proper level. Use only unleaded fuel in your vehicle.
If
you use leaded fuel, you could damage your oxygen (OS) sensor and
three-way catalytic converter.
The Malfunction Indicator Lamp
(SERVICE ENGINE SOON) on your
instrument panel lets you know when your emission control syste\
m needs
service. The light will come on briefly when you start your e\
ngine 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 (AIR) System
You may have this system. It lets you know if your engine control module,
wiring harness or solenoid need service.
If the Malfunction Indicator Lamp
(Service Englne Soon) comes on, you need service.

The Certificationflire 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 o\
f the vehicle,
all occupants, fuel and cargo.
The Certificationnire 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.
And,
if you do have a heavy load, you should spread it out.
A
Do not load your vehicle any heavier than the GVWR or the I
maximum front and rear GAWRs. If you do, parts on your vehicl\
e
can break, or
it can change the way your vehicle handles. These
could cause you
to lose control. Also, overloading can shorten the
life of your vehicle.
Using heavier suspension components
to get added durability might not
change your weight ratings. Ask your dealer to help you load your vehicle the
right way.
