Theft-Deterrent System (Without the Intrusion Sensor) (Some Models)

If the theft deterrent system detects an inappropriate entry into the vehicle, which could result in the vehicle or its contents being stolen, the alarm alerts the surrounding area of an abnormality by sounding the horn and flashing the hazard warning lights.

 

The system will not function unless it's properly armed. So when you leave the vehicle, follow the arming procedure correctly.
