The 1992 Cadillac Brougham doesn't have a sophisticated computer-controlled oil change reminder system like many later cars. There's no "Change Oil" lamp to reset in the traditional sense. Instead, it likely relies on the driver to remember and track oil changes based on mileage or time intervals. The owner's manual will specify the recommended interval.
Therefore, there's no reset procedure. You simply change the oil according to the recommended schedule and that's it.
