Shift Lock Manual Release

The transmission has an electric shift lock. The key must be in the ON/RUN position and the brake pedal pressed, so the transmission selector lever can be moved from the P (Park) or the N (Neutral) position. If the battery has lost power, the selector cannot be moved unless the shift lock manual release is engaged manually.
