Theft-Deterrent Systems
Vehicle theft is a big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put on it can make it
impossible to steal. However, there are ways you
can help.
Passlockž
Your vehicle is equipped with the Passlockž
theft-deterrent system.
Passlock
žis a passive theft-deterrent system. Passlockž
enables fuel if the ignition lock cylinder is turned with
a valid key. If a correct key is not used or the ignition
lock cylinder is tampered with, fuel is disabled.During normal operation, the SECURITY light will go off
approximately ®ve seconds after the key is turned
to RUN.
If the engine stalls and the SECURITY light ¯ashes,
wait until the light stops ¯ashing before trying to restart
the engine. Remember to release the key from
START as soon as the engine starts.
If the engine is running and the SECURITY light comes
on, you will be able to restart the engine if you turn
the engine off. However, your Passlock
žsystem is not
working properly and must be serviced by your
dealer. Your vehicle is not protected by Passlock
žat
this time. You may also want to check the fuse.
See
Fuses and Circuit Breakers on page 5-93. See your
dealer for service.
2-18

If a bulb is burned out, replace it to help avoid an
accident. If the arrows don't go on at all when you signal
a turn, check for burned-out bulbs and a blown fuse.
See
Fuses and Circuit Breakers on page 5-93.
If you have a trailer towing option with added wiring for
the trailer lamps, a different turn signal ¯asher is
used. With this ¯asher installed, the signal indicator will
¯ash even if a turn signal bulb is burned out. Check
the front and rear turn signal lamps regularly to make
sure they are working.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each ¯ash of the
turn signal. To turn off the chime, move the turn signal
lever to the center position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or high
to low, pull the multifunction lever all the way toward
you. Then release it.
When the high beams are
on, this indicator light
located on the instrument
panel cluster also will
be on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even if your headlamps are in automatic.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are in automatic or on low beam,
your high-beam headlamps will turn on. They'll stay on
as long as you hold the lever toward you and the
high-beam indicator located on the cluster comes on.
Release the lever to return to normal operation.
3-7

Dome Lamps
The dome lamps will come on when you open a door,
except with the liftgate glass (if equipped).
You can also turn the dome lamps on by turning the
thumbwheel, located next to the exterior lamp control, all
the way up. In this position, the dome lamps will
remain on whether a door is opened or closed.
You can use the DOME OVERRIDE button, located
near the exterior lamp control, to set the dome lamps to
come on automatically when a door is opened, or to
remain off. To turn the lamps off, press the button into
the in position, the dome lamps will remain off when
a door is open. To return the lamps to automatic
operation, press the button again and return it to the out
position. With the button in this position, the dome
lamps will come on when you open a door.
Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading and glove box lights if they are left on for more
than 20 minutes when the ignition is off. This will keep
your battery from running down.
If the battery run-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:
·Shut off all lamps and close all doors, or
·turn the ignition key to RUN.
Accessory Power Outlets
You can plug accessory electrical equipment into an
accessory power outlet. Just pull on the outlet cover to
remove it and follow the proper installation instructions
that are included with any electrical equipment that
you install.
The accessory power outlet is located on the
passenger's side of the front storage compartment.
These circuits are protected by a fuse and have
maximum current levels.
Certain power accessory plugs may not be compatible
to the power accessory outlet and could result in
blown vehicle or adapter fuses. If you experience a
problem, see your dealer for additional information on
the power accessory plugs.
Notice:When using an accessory power outlet,
maximum electrical load must not exceed 25 amps.
Always turn off any electrical equipment when
not in use. Leaving electrical equipment on for
extended periods will drain your battery.
Notice:Power outlets are designed for accessory
plugs only. Do not hang any type of accessory
or accessory bracket from the plug. Improper use of
the power outlet can cause damage not covered
by your warranty.

Electrical System
Add-On Electrical Equipment
Notice:Don't add anything electrical to your
vehicle unless you check with your dealer ®rst.
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 on page 1-69.
Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. An electrical overload will cause the
lamps to ¯icker 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 windshield before using the windshield wipers.
If the overload is caused by some electrical problem and
not snow, etc., be sure to get it ®xed.
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, protecting the circuit until the problem is ®xed or
goes away.
5-92

Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. 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.
Spare fuses and a fuse puller are located in the
underhood fuse block. You can remove fuses with the
fuse puller. Remember to replace any of the spare fuses
you use, so you will have some if you ever need them
again.
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.
There are two fuse blocks in your vehicle: one is inside
the vehicle and one is in the engine compartment.
Instrument Panel Fuse Block
The fuse block is located on the lower portion of the
instrument panel on the driver's side.
5-93

Underhood Fuse Block
The underhood fuse block is located toward the rear of
the engine compartment on the driver's side of the
vehicle.
Lift the hood and open the cover to gain access to this
fuse block.
A fuse puller is included in the underhood fuse block.
You will also ®nd spare fuses.Feed Usage
