Add-on Electrical Equipment
I 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.
Headlamp Wiring
The headlamp 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 Wiper Fuses
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 windshield before using the windshield
wipers.
If the overload is caused by some electrical
problem and
not snow, etc., be sure to get it fixed.

Downloaded from www.Manualslib.com manuals search engine Instrument Panel Fuse Block
The fuse block access door
is on the driver's side of the
instrument panel above the
hood release lever.
You can remove the cover
by turning the fastener
counterclockwise.
You can remove fuses with a fuse extractor. The fuse
extractor
is mounted to the fuse block access door.
To remove fuses if you don't have a fuse extractor, hold
the end of the fuse between your thumb and index finger
and pull straight out. Be sure to use
the correct fuse.
If you ever have a
problem on the road and don't have a spare fuse,
you can "borrow" one of the correct value. 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 of the value you need. Replace it
as soon
as you can. See "Fuses and Circuit Breakers'' in the
Index for more information.
