Modes AVG ECON: Shows your average fuel economy since you last reset this mode. Average fuel economy is viewed as a long term approximation of your overall driving and driving conditions. To learn the average fuel economy from a new starting point, press the RESET button while the average fuel economy is displayed in the DIC. INSTANTANEOUS FUEL ECONOMY: Shows your current fuel economy. Instantaneous fuel economy varies with your driving conditions, such as acceleration, braking and the grade of the road being traveled. The instantaneous fuel economy display cannot be reset, therefore the reset button has no effect while in this mode. OIL LIFE MONITOR: Shows an estimate of the oil's remaining useful life. When the oil life index is less than 10%, the CHANGE OIL SOON light will come on. When you have the oil changed according to the maintenance schedule (see "Maintenance Schedule" in the Index), you will have to reset the CHANGE OIL SOON light. To reset the CHANGE OIL SOON light, see "Oil Life System" in the Index. Also, see "Engine Oil, When to Change" and "Maintenance Schedule" in the Index. RANGE: Shows the approximate distance you can drive without refueling. This is based on the amount of fuel in the tank and on the fuel economy of the most recent 25 miles (40 km). Pressing RESET while in this mode will have no effect. BOOST GAGE: If you have the supercharged engine, this gage will show the amount of boost your engine is receiving. Pressing RESET while in this mode will have no effect. 2-82
