It's all about the trip-reset button, with the ignition on, let the seatbelt alarm go off (if you're not wearing it) preferably wear the seatbelt and within 2 seconds of turning the key to light up the ignition lights, (do not start engine) press and hold the trip-reset button. You will NOT lose the trip count - it'll go to zero initially, show you the mileage to the next service interval, and the trip counter will go back to what it was.
The display resets back to the normal computer after about 30 secs.
