Disarming the System You can disarm the system by doing any one of the following: • Press the remote keyless entry transmitter unlock button. • Turn the ignition on. If the system is armed and the trunk is opened using the trunk release button on the transmitter, the system will temporarily disarm itself and re-arm when the trunk has been closed. This allows you to exit the vehicle, lock the doors using the transmitter, and open the trunk using the transmitter without having to disarm and re-arm the system. Once the system is disarmed, the security light will stop flashing. • Opening any other door. This will immediately cause a full alarm of horn and lights for thirty seconds. When an alarm event has finished, the system will re-arm itself automatically. How to Turn Off the System Alarm To turn off the system alarm, do one of the following: • Press the lock button on the remote keyless entry transmitter. The system will then re-arm itself. • Press the unlock button on the remote keyless entry transmitter. This will also disarm the system. • Insert the key in the ignition and turn it on. This will also disarm the system. How the System Alarm is Activated If the system is armed, it can be activated by either: • Opening the driver's door or trunk. This will cause a ten second pre-alarm chirp followed by a thirty second full alarm of horn and lights. How to Detect a Tamper Condition If you hear three chirps when you press the unlock, lock, or trunk release buttons on the remote keyless transmitter, it means that the content theft security system alarm was previously activated. 105
