Vehicle Identification Number (VIN)
This is the legal identifier 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 Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code. This
code will help you identify your engine, specifications
and replacement parts.
Service Parts Identification Label
You'll find this label on the under side of the spare tire
cover in the trunk. It's very helpful if you ever need to
order parts. On this label is:

your VIN,

the model designation,

paint information and

a list of all production options and
special equipment.
Be sure that this label is not removed from the vehicle.

6-64 Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of fires caused
by electrical problems.
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 a MaxiFuse should blow, see your dealer
for service immediately.
If you ever have a problem on the road and don't have a
spare fuse, you can ªborrowº one that has the same
amperage. 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 the correct amperage.
Replace it as soon as you can.
The MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near the engine
compartment on the passenger's side and the other under
the rear seat on the driver's side. If a MaxiFuse should
blow, have your vehicle serviced by your
dealer immediately.Underhood Junction BlockThe front Bussed Electrical Center (BEC) is located
next to the engine on the passenger's side of the vehicle.
To access the fuse block, push in the two tabs located on
the top and the bottom of the fuse block cover.
