To arm the system: • If Passive Arming is activated through the vehicle personalization feature, the system will arm automatically after you close the door and take at least one keyless access transmitter with you. The security light will turn on. After 60 seconds the light should turn off. The theft-deterrent system is armed. See Vehicle Personalization on page 2-61. 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 2-61. 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. • Press the lock button on the keyless access 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. 2-22
