Brake/Transmission Shift Interlock System

This vehicle is equipped with a Brake Transmission Shift Interlock (BTSI) that holds the shift lever in the PARK position unless the brakes are applied. To move the shift lever out of the PARK position, the ignition switch must be turned to the ON/RUN or START position (engine running or not) and the brake pedal must be pressed.
