Electrical System

Add-On Electrical Equipment

Notice: Do not add anything electrical to your
vehicle unless you check with your dealer
first. 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, see Servicing Your Airbag-Equipped
Vehicle on page 88.

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 fixed.
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 fixed
or goes away.
