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 102.
Headlamp Wiring
The headlamp wiring is protected by internal fuses
in the fuse block. An electrical overload will cause
the lamps to go off and remain off. If this happens,
have your headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker and a fuse. If the motor
overheats due to heavy snow, etc., 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 in the floor console 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.
