Electrical System

Add-On Electrical Equipment

Notice: Don't add anything electrical to your
vehicle unless you check with your dealer first.
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, see Servicing
Your Airbag-Equipped Vehicle on page 1-56.
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 fixed
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 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.
You will find 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 immediately.
