Vehicle Identication
Vehicle Identication Number (VIN)
This is the legal identier for your vehicle. It appears on
a plate in the front corner of the instrument panel, on
the driver’s side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certication and Service Parts
labels and the certicates of title and registration.
Engine Identication
The eighth character in the VIN is the engine code.
This code will help you identify your vehicle’s engine,
specications, and replacement parts.
Service Parts Identication Label
You will nd this label on the inside of the access panel
located on the driver’s side of the rear of the vehicle.
It is very helpful if you ever need to order parts.
On this label, you will nd the following:
VIN
Model designation
Paint information
Production options and special equipment
Be sure that this label is not removed from the vehicle.

Electrical System
Add-On Electrical Equipment
Notice:Don’t add anything electrical to your
vehicle unless you check with your dealer rst.
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 airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-85.
Headlamp Wiring
The headlamp wiring is protected by internal fuses in
the fuse block. An electrical overload will cause the
lamps to go off and remain off. If this happens, have
your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an internal
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, be sure to get it xed.
Power Windows and Other Power
Options
Circuit breakers in the oor console fuse block 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 xed.
5-100

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.
Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical
size and rating.
If you ever have a problem on the road and do not have
a spare fuse, you can borrow one that has the same
amperage. Just pick a feature of your vehicle that
you can get along without – like the radio or cigarette
lighter - and use its fuse, if it is the right amperage.
Replace it as soon as you can.
There are two fuse blocks in your vehicle: the oor
console fuse block and the underhood fuse and
relay center.
Floor Console Fuse Block
The oor console fuse block is located to the left of the
glove box near the oor. Pull the door open to access
the fuse block.
