Locks and Security
Arming the system
When armed, the active anti-theft system is designed to notify you of an
unauthorized entry. When unauthorized entry or towing occurs, the
system will flash the turn signal lamps and interior lamps and sounds the
security horn.
The system is ready to arm whenever the key is out of the ignition. Any
of the following actions will arm the alarm system:
• Press the remote transmitter lock control one time to arm the system.
• Lock all doors using the interior power lock switch while the driver or
passenger door is open and then becomes closed.
• Lock the driver door with the key in the key lock cylinder (this will
not however arm the interior motion or vehicle incline sensing
systems or lock the passenger door).
If all the closures (doors, trunk, hood) are closed, the turn signal lamps
will flash once. If any closure is not properly closed the parklamps will
not flash. Note: Locking the driver door with the key does not lock the
passenger door. Use the power door lock control or manually lock the
passenger door to ensure the vehicle is properly secured.
The system will wait 20 seconds after locking before triggering an alarm.
After the 20–second pre-arm phase, the power door unlock control is
disabled (for more information, refer to Power door trim switch inhibit
section earlier in this chapter) to further protect your vehicle.
Disarming the system
You can disarm the active anti-theft system by any of the following
actions:
• Unlock the doors by using the remote entry transmitter.
• Unlock the driver's door with the key in the door lock cylinder.
• Turn the ignition to the on position with a programmed coded ignition
key.
Note: Unlocking the trunk inhibits the motion and tilt sensing systems,
but the system continues to monitor the doors and hood. Once the trunk
becomes closed the motion and tilt sensing systems will rearm.
