How do you disable the seat belt chime on Lincoln Navigator?

To disable the seat belt chime on a Lincoln Navigator, you typically need to follow these steps: Sit in the driver's seat with the door closed and turn the ignition to the "On" position without starting the engine. Buckle and unbuckle the seat belt three times, and then turn the ignition back to the "Off" position. This should deactivate the chime; however, the exact process may vary slightly depending on the model year, so it's advisable to consult the owner's manual for specific instructions.
