The theft deterrent system provides a fourth Red button on the transmitter. This button is the alarm/panic button. If this button is pressed the vehicle horn will sound and the headlamps will flash. To turn this feature off, either push the panic button again or turn the ignition system to the RUN position. This feature will not work if the ignition is on or if the transmitter is 30 feet (9 meters) or more away from the vehicle.
