Service Schedule
Due dates use whichever comes first — mileage or time — same logic as the FJ's dashboard.
Mileage entry here is manual/occasional, not estimated between updates. Due-in numbers are only as fresh as the last mileage you entered.
Maintenance Log
Dated service history — mileage, work done, cost, DIY or shop.
