Essentially, the owner contacts the Police, which in turns contacts OnStar. OnStar then sends a signal to the car which disengages the throttle, but maintains the car’s steering and braking system — allowing the thief to maneuver off the road safely. Unknowingly to the thief, the car’s hazard lights are engaged and an “Engine Power is Reduced” message is shown on the gauge cluster.
