The second-generation Jeep Grand Cherokee (WJ/WG) 1999-2005 introduced the Quadra-Drive system and the 4.7-litre PowerTech V8 alongside the familiar 4.0 straight-six, all in a more refined unibody package. Even on this older model, an oil change or scheduled service leaves the maintenance reminder showing until it is reset. Owners here will mainly want the oil service reset to clear the change-engine-oil light, and a general service reminder reset after the full interval has been completed. Because the electronics are simpler than later Jeeps, the reset is usually a quick dash-button sequence.
