Your vehicle is equipped with the IntelligentOil-Life Monitor system, which displays amessage in the information display at theproper oil change interval. This interval maybe up to one year or 10,000 mi (16,000 km).
When the oil change message appears inthe information display, it is time for an oilchange. Make sure you perform the oilchange within two weeks or 500 mi (800 km)of the message appearing. Make sure youreset the Intelligent Oil-Life Monitor aftereach oil change. See Oil Change IndicatorReset (page 365).
If your information display resets prematurelyor becomes inoperative, you should performthe oil change interval at six months or5,000 mi (8,000 km) from your last oilchange. Never exceed one year or 10,000 mi(16,000 km) between oil change intervals.
