Press the GAGE INFO button until OIL LIFE INDEX appears in the display. The OIL LIFE INDEX NORMAL display will show an estimate of the oil's remaining useful life. When the oil life index is less than 10 percent, the display will show OIL LIFE INDEX CHANGE OIL.

Also check the tire pressure in all four tires as soon as you can. See Inflation - Tire Pressure on page 5-65 and Check Tire Pressure System on page 5-66. There are times when you will have to reset (calibrate) the Check Tire Pressure System. See Check Tire Pressure System on page 5-66.
