Brake Shift Interlock Override

Note. If it is necessary to use the override procedure to move the selector lever out of the PARK position, it is possible that a fuse has blown and the brake lights are not operational. Before driving the vehicle, verify that the brake lights are working. This vehicle is equipped with a brake shift interlock feature that prevents the selector lever from being moved out of PARK when the ignition is in the ON position unless the brake pedal is depressed. If the selector lever cannot be moved out of the PARK position when the ignition is in the ON position and the brake pedal is depressed carry out the following procedure

1. Apply the parking brake.
2. Remove the access panel.
3. Using an suitable tool, depress the brake shift interlock override mechanism on the selector lever, apply the brake, depress the button on the selector lever and move the selector lever into NEUTRAL.
4. Start the vehicle.
5. Install the access panel.
