If a locked door is opened without the key or the remote
keyless entry transmitter, the alarm will go off. The
headlamps and parking lamps will flash for two minutes,
and the horn will sound for 30 seconds, then will turn
off to save the battery power. You can choose different
feedback options for the alarm. See
Driver Information
Center (DIC) on page 3-49
.
Remember, the theft-deterrent system won’t activate if
you lock the doors with a key or use the manual
door lock. It activates only if you use a power door lock
switch with the door open, or with the remote keyless
entry transmitter. You should also remember that
you can start your vehicle with the correct ignition key if
the alarm has been set off.
Here’s how to avoid setting off the alarm by accident:
If you don’t want to activate the theft-deterrent
system, the vehicle should be locked with the door
key
after
the doors are closed.
Always unlock a door with a key, or use the remote
keyless entry transmitter. Unlocking a door any
other way will set off the alarm.
If you set off the alarm by accident, unlock any door with
the key. You can also turn off the alarm by pressing
unlock on the remote keyless entry transmitter. The alarm
won’t stop if you try to unlock a door any other way.
Testing the Alarm
The alarm can be tested by following these steps:
1. From inside the vehicle, lower the driver’s window
and open the driver’s door.
2. Activate the system by locking the doors with the
power door lock switch while the door is open, or
with the remote keyless entry transmitter.
3. Get out of the vehicle, close the door and wait for
the security light to go out.
4. Then reach in through the window, unlock the door
with the manual door lock and open the door. This
should set off the alarm.
While the alarm is set, the power door unlock switch is
not operational.
If the alarm does not sound when it should but the
headlamps flash, check to see if the horn works. The
horn fuse may be blown. To replace the fuse, see
Fuses
and Circuit Breakers on page 5-111
.
If the alarm does not sound or the headlamps do not
flash, the vehicle should be serviced by your dealer.

Accessory Power Outlets
With accessory power outlets you can plug in auxiliary
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle is equipped with many accessory power
outlets.
One outlet is located in the center console. Press the
button on the side of the console door to access
the outlet.
There may also be an accessory power outlet located
on the back of the center console above the cupholder.
Do not try to put the cigarette lighter in any of the
accessory outlets.
Notice:
Adding any electrical equipment to your
vehicle may damage it or keep other components
from working as they should. The repairs would not
be covered by your warranty. Check with your
dealer before adding electrical equipment.
Certain power accessory plugs may not be compatible
with the accessory power outlets and could result in
blown vehicle or adapter fuses. If you experience
a problem, see your dealer for additional information on
the accessory power plugs.
Notice:
Improper use of the power outlet can cause
damage not covered by your warranty. Do not
hang any type of accessory or accessory bracket
from the plug because the power outlets are
designed for accessory power plugs only.
Ashtrays and Cigarette Lighter
The front ashtray and lighter are located in the center
console near the cupholders. Press on the access door
to open it and use the ashtray and lighter.
Notice:
If you put papers or other flammable items
in the ashtray, hot cigarettes or other smoking
materials could ignite them and possibly damage
your vehicle. Never put flammable items in the
ashtray.
To remove the ashtray, pull it from the center console.
Slide it back in and push down to be sure it is secure.
To use the cigarette lighter, push it in all the way, and let
go. When it’s ready, it will pop back out by itself.
Notice:
Holding a cigarette lighter in while it is
heating will not allow the lighter to back away from
the heating element when it is hot. Damage from
overheating may occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.
