Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
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 86.
Headlamps
The headlamp wiring is protected by four fuses.
An electrical overload will cause a lamp to go
on and off. If this happens, have your headlamp
wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by a
circuit breaker and a fuse. If the motor overheats
due to heavy snow or ice, 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 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.
502

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.
If you ever have a problem on the road and
don’t have a spare fuse, you can borrow one
that has the same amperage. 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 the correct amperage.
Replace it as soon as you can.
Engine Compartment Fuse Block
The fuse block is located under the hood in the
engine compartment on the driver’s side of
the vehicle. SeeEngine Compartment Overview
on page 396for more information on location.
Remove the primary cover by pressing the
two locking tabs. Remove the secondary cover by
snapping off while lifting. To reinstall the fuse
panel cover, reverse the sequence.
