Abstract
To prevent an automatic transmission vehicle from creeping when the engine is started with the shift lever set to Neutral position, an alarm is produced when the shift lever is set to shift positions other than Park position and simultaneously the ignition key is removed from the ignition key cylinder or inserted into the ignition key cylinder at engine halt. Therefore, whenever the driver removes the ignition key from the ignition key cylinder or inserts the ignition key into the ignition key cylinder at engine halt, the driver is forced to securely set the shift lever to Park position on the alarm signal.
