a plate in the front corner of the instrument panel, on
the driver 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 helps you identify your vehicle’s engine,
specications, and replacement parts. SeeCapacities
and Specifications on page 5-113for your vehicle’s
engine code.

This label is on the spare tire cover. It is very helpful if
you ever need to order parts. The label has the

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer/retailer
rst. Some electrical equipment can damage your
vehicle and the damage would not be covered by
your warranty. Some add-on electrical equipment can
keep other components from working as they should.
Add-on equipment can drain your vehicle’s battery, even
if your vehicle is not operating.
Your vehicle has an airbag system. Before attempting to
add anything electrical to your vehicle, seeServicing
Your Airbag-Equipped Vehicle on page 1-72.
Power Windows and Other Power
Options
Circuit breakers in the rear 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
or goes away.
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 res
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.
You will nd a fuse puller clipped in both of the fuse
blocks. Snap the wide end of the fuse puller at the side
indentations and pull the fuse out.
The MaxiFuses are located in two fuse blocks, one
located in 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/retailer immediately.

Underhood Fuse Block
The underhood fuse block is located on the passenger side of the engine compartment. Remove the fuse cover and
secondary service cover to access the fuse block.
Notice:Spilling liquid on any electrical components on your vehicle may damage it. Always keep the covers
on any electrical component.

the driver side. The rear seat cushion must be removed

parts, and do not store anything under the seats.

front hooks.

5-108

To reinstall the rear seat cushion, do the following:
{CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will not
provide the protection needed in a crash. If the
safety belt has not been routed through the
seat cushion at all, it will not be there to work
for the next passenger. The person sitting in
that position could be badly injured. After
reinstalling the seat cushion, always check to
be sure that the safety belts are properly
routed and are not twisted.
1. Buckle the center passenger position safety belt,
then route the safety belts through the proper slots
in the seat cushion. Do not let the safety belts
get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear-locating guides hook into
the wire loops on the back frame.
3. With the seat cushion lowered, push rearward and
then press down on the seat cushion until the
spring locks on both ends engage.
4. Check to make sure the safety belts are properly
routed and that no portion of any safety belt is
trapped under the seat. Also make sure the seat
cushion is secured.
