ABSTRACT:
An alarm system which signals to the driver a first alarm whenever he opens a vehicle door and the selector lever of an automatic transmission is not in its full park position. The system signals to the driver and also to persons external to the vehicle a second different alarm whenever, in addition, the driver leaves his seat and the selector lever is not in its full park position or the parking pawl fails to properly engage the parking gear even though the selector lever is in its proper park position. A manual switch may be operated to selectively disconnect the alarms, with an automatic operator being provided to close this switch should it accidently be left in its open condition.
