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 air bag system. Before attempting to
add anything electrical
to your vehicle, see “Servicing
Your Air Bag-Equipped Vehicle” in the Index.
Headlamps
The headlan1p wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to flicker on and off, or
in some cases to remain
off.
If this happens, have your headlamp wiring checked
right away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and
a fuse. If the motor overheats due to heavy
snow, etc., the wiper will stop
until the motor cools.
Although the circuit is protected from electrical
overload, overload
due to heavy snow, etc., may cause
wiper linkage damage. Always clear ice and heavy snow
from the the windsl~ield before using the windshield
wipers.
If the overload is caused by some electrical
problem and not snow, etc., be
sure to get it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too
heavy, the circuit breaker opens and closes.
This protects
the circuit until the current load returns to
normnl or the problem is fixed.
