2026 Jeep Wagoneer S maintenance schedule
The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.
A dot means the service is due at that mileage or after that many years, whichever comes first. Engines: ELD, ELJ.
