Arming with the Power Lock Switch Your alarm system will arm when the key is removed from the ignition and you use the driver's power door lock switch, with the driver's door open or the passenger's door power door lock switch with the passenger's door open to lock the vehicle. If you would like to turn on power door lock switch arming, see DIC Vehicle Personalization (Uplevel Only) on page 3-69. When the security light flashes quickly the system is arming. After all doors and the liftgate are closed and locked, the security light will begin flashing at a very slow rate to let you know the system is armed.

While armed, the doors will not unlock with the power door lock switch. Once armed, the alarm will go off if someone tries to enter the vehicle without using the remote keyless entry transmitter or a key, or turns the ignition to RUN. The horn will sound and the turn signal lamps will flash for up to two minutes.

If you press the transmitter's lock button twice within five seconds, the horn will sound. After all doors and the liftgate are closed and locked, the security light will begin flashing at a very slow rate to let you know the system is armed. 2-27
