1. Apply the parking brake.
2. Turn the key to the off position.
3. Remove the access plug on top of
the steering column.
4. Using a flat-head screwdriver or
similar tool, move the brake-shift
interlock actuator spindle toward
the left, apply the brake, place the
key in the on position and shift the
transmission into N (Neutral).
5. Start the vehicle.
6. Reinstall the access plug.
WARNING: Do not drive your vehicle until you verify that the
brakelamps are working.
WARNING: When doing this procedure you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement always fully set parking brake prior
to doing this procedure. Use wheel chocks if appropriate.
WARNING: If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.
