If your vehicle has this option, it has a content theft-deterrent alarm system.

A light located in your Twilight Sentinel® cluster, above the fog lamp button, will begin to flash 30 seconds after the vehicle ignition is turned off to let you know the system has been 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, breaks a window, tries to damage the vehicle or turns the ignition to ON. If any of these do occur, the horn will sound and the parking lamps will flash for up to two minutes.
