2004 Subaru Baja Base, AutomaticFACTORY OEM SERVICE PROCEDURE

Shift Lock and Key Interlock System: General

To increase safety during standing start, the shift lock system prevents movement of the select lever from the "P" position to any other position unless the brake pedal is depressed. This system is also provided with a key interlock function which prevents removal of the ignition key from the key cylinder unless the selector lever is placed in the "P" position.
