Programmable Automatic Door
Locks
The vehicle was programmed so when the doors are
closed, the ignition is on, and the shift lever is moved
out of P (Park), all the doors will lock.
The front doors can still be opened from the inside while
the doors are locked. If a rear passenger needs to exit
the vehicle, have that person use the manual knob or
use the power door lock switch on either front door.
When the door is closed again, it will not lock
automatically. Use the manual knob or the power
door lock switch to lock the door.
The doors were also pre-programmed to unlock every
time the shift lever is moved into P (Park).
The power door locks can be programmed through the
radio display. The radio display allows you to choose
various lock and unlock settings. For more information
on programming, seeVehicle Personalization
on
page 3‑59.

each door.
To set the locks, insert a key into the slot and turn it to
the horizontal position. The door can only be opened
from the outside with the door unlocked. To return the

Theft-Deterrent Systems
This vehicle has theft-deterrent features, however, they
do not make it impossible to steal.
Theft-Deterrent System
Your vehicle has a theft-deterrent alarm system.

located on the instrument
panel cluster.
If the ignition is off and a door is open, the security light
will flash, reminding you to arm the theft-deterrent
system.
To arm the system:

transmitter. If the door is closed when the lock
button is pressed, the security light will stay
illuminated for 30 seconds. After the security light
goes off, the theft‐deterrent system is armed.
Pressing the lock button twice will arm the system
immediately. If the vehicle is locked using the keyless access
transmitter and the trunk lid, hood or a door is
open or not closed completely, the security light
will flash for 60 seconds and then turn off. The
theft‐deterrent system is armed but the alarm will
not sound if the trunk lid, hood or door that was not
closed completely is tampered with or opened. The
alarm will sound for the trunk lid, hood or a door
that was completely closed at the time the vehicle
was locked using the keyless access transmitter.
.Exit the vehicle and lock the door with the power
door lock switch or lock button on the keyless
access transmitter. The security light should flash.
Close the door. The security light will stop flashing
and stay on. After 30 seconds the light should turn
off, the theft‐deterrent system is armed.

personalization feature, the system will arm
automatically after you close the door and take
at least one keyless access transmitter with you.

light should turn off. The theft-deterrent system is
armed. See
Vehicle Personalization
on page 3‑59.

If a door, hood, or the trunk is opened without the
keyless access transmitter, the horn will sound for
30 seconds and the lamps will flash for two minutes.
The vehicle cannot be started without a keyless access
transmitter.
The Theft-Deterrent system will not arm if :
.The key is used to turn the key cylinder to the lock
position.
.The driver's door is locked using the power door
lock switch after the doors are closed.
The vehicle can be programmed to automatically unlock
the doors and disarm the theft‐deterrent system when
you approach the vehicle and the keyless access
transmitter is with you. See Vehicle Personalization
on
page 3‑59.
Pressing the unlock button on the keyless access
transmitter or using the key to unlock the driver's door
disarms the theft-deterrent system. Unlocking a door
any other way while the system is armed will activate
the alarm.
Testing the Alarm
1. From inside the vehicle, roll down the window, then get out of the vehicle, keeping the door open.
2. From outside of the vehicle, with the door open, lock the vehicle using the power door lock switch
or the keyless access transmitter and close the

will flash.
You can turn off the alarm by pressing the unlock button
on the keyless access transmitter or by starting the car.
If the alarm does not sound when it should, check to
see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers
on
page 6‑115. If the fuse does not need to be replaced,
you may need to have your vehicle serviced.
To reduce the possibility of theft, always arm the
Theft-Deterrent system when leaving your vehicle.
