When abnormality indicative possible auto theft occurs, the anti-theft system transmits that fact to a remote control unit, which thereby sounds an alarm. The anti-theft system at the same time turns on the power of the mobile telepone system so as to make it ready for being capable of external calls, so that the driver who is remote from the car can ascertain the state of the anti-theft system by calling the mobile telephone system before running to the car.
