Here's what the manual states.
VEHICLE SECURITY ALARM — IF EQUIPPED
The vehicle security alarm monitors the vehicle doors, swing gate, and ignition for unauthorized operation. While the vehicle security alarm is armed, interior switches for door locks are disabled. The vehicle security alarm pro- vides both audible and visible signals when alarming. The horn will sound, the headlights will turn on, the park lamps and/or turn signals will flash repeatedly for three minutes. If the disturbance is still present (driver’s door, passenger door, other doors, ignition) after three minutes, the headlights, park lamps and/or turn signals will flash for an additional 15 minutes.
NOTE: The Panic Alarm and the vehicle security alarm are 3 quite different. Please take a moment to activate the Panic Alarm and the vehicle security alarm to hear the differ- ences in the horn. In case one should go off in the future, you will need to know which mode has been activated in order to deactivate it.
Rearming The System
If something triggers the alarm, and no action is taken to disarm it, the vehicle security alarm will turn off the horn after three minutes, turn off all of the visual signals after 15 minutes, and then the vehicle security alarm will rearm itself.
To Arm The System
The vehicle security alarm will set when you use the Remote Keyless Entry key fob to lock the doors and swing gate, or when you use the power door lock switch while the door is open. After all the doors are locked and closed, the vehicle security light (located on the instrument cluster) will flash rapidly for about 16 seconds to signal that the vehicle security alarm is arming. During this 16-second arming period, opening any door or the swing gate will cancel the arming. If the vehicle security alarm is success- fully set, the vehicle security light will flash at a slower rate to indicate the vehicle security alarm is armed.
To Disarm The System
To disarm the vehicle security alarm, you will need to push the unlock button on the key fob, or turn the ignition switch to the ON/RUN position. If something has trig- gered the vehicle security alarm in your absence, the horn will sound three times, and the exterior lights blink three times when you unlock the doors. Check the vehicle for tampering.
The vehicle security alarm is designed to protect your vehicle; however, you can create conditions where the vehicle security alarm will arm unexpectedly. If you remain in the vehicle and lock the doors with the key fob, once the vehicle security alarm is armed (after 16 seconds), when you pull the door handle to exit, the alarm will sound. If this occurs, push the unlock button on the key fob to
disarm the vehicle security alarm. You may also acciden- tally disarm the vehicle security alarm by unlocking the driver’s door with the key and then locking it. The door will be locked but the vehicle security alarm will not arm.
NOTE:
• Unlocking the doors with the manual door lock plung- ers or the driver’s door lock cylinder will not disarm the vehicle security alarm.
• When the vehicle security alarm is armed, the interior power door lock switches will not unlock the doors.
