A vehicle such as an automobile includes various auxiliary devices for implementing auxiliary functions such as electrical equipment, windows, doors, a parking brake, a transmission and the like, in addition to a principal scheme for a running operation of the vehicle. The vehicle also includes two alarms, one being provided for raising an alarm inside the vehicle and the other being provided for raising an alarm outside the vehicle. When a driver leaves the vehicle after he ends the drive, a predetermined undesired state of various auxiliary devices, such as a switch for the circuit of electrical equipment being kept turned on, the window or door being not fully closed, the parking brake being not put on and so on is detected, when the key switch is turned off. Upon detection of such undesired state, first the inside alarm is energized and after a predetermined time period the outside alarm is energized. As a result, it is ensured that a driver does not quit the vehicle with various devices in an undesired state.
