Park Lock System







The Park Lock/Brake Transmission Shift Interlock system is a safety feature that serves three purposes: To prevent moving the shifter out of "PARK" when the lock cylinder is in the "LOCK" position, to prevent moving the lock cylinder to the "LOCK" position unless the shifter is in "PARK," and to prevent from shifting the car out of park unless foot is on the brake.
