From the owner's manual:
The active anti-theft system is designed to warn you on the event of an unauthorized entry to your vehicle and is also designed to prevent the unwanted towing of the vehicle.
When the vehicle is locked and armed, the active anti-theft system monitors the following:
Movement inside the vehicle
Change in vehicle inclination
Note: the active anti-theft system includes a motion detection system which monitors the passenger cabin and a vehicle incline sensor which detects changes in the vehicle attitude.
There are a couple more paragraphs explaining and cautioning about the system. My car has it and I have only had it go off once when I didn't set the emergency brake firmly enough and the car rolled down the driveway about 15 feet to the street gutter, no damage. Pressing the remote to lock automatically turns the system on when all doors, windows, hood and trunk are closed.
And, gearhead, I was born and raised in Sugarland, still have family there, too.
