Circuit/System Description
WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.
The inclination sensor detects changes in the parked angle of the vehicle. If a change greater than 0.3° for a 7 second period is detected, the vehicles content theft alarm is sounded. The sensor recalibrates itself each time the vehicle is parked, which allows it to account for parking on steep grades without unintentional activation.
