yellowblue Fuel Data Panel Press the AVG button to display the average mile per gallon (AVG MPG). You can also display it in metric units by pressing the ENG MET button. When AVG MPG is selected, the total distance is divided by the total fuel used. When the INST button (Instantaneous Fuel Economy) is selected, you will see what the fuel economy is at that instant. The computer takes a new reading twice every second. It will show economy up to 70 miles per gallon (or 2 L per 100 km). To reset the average fuel economy, press the INFORMATION SKIP button until the AVG MPG is displayed on the Driver Information Center (DIC). Press and hold the RESET NO button until both the fuel data center and DIC display reads 0.0. Digital Cluster For vehicles equipped with an analog cluster (not shown), fuel data can be obtained by pressing the SKIP INFO button. See "Analog Control Buttons" in the Index. The fuel data panel tells you all you need to know about the fuel economy and how far you can travel with the fuel remaining. The RANGE display shows how far the computer thinks you can travel with the fuel that is in the tank. The computer does not know what driving conditions will be like for the rest of your trip, so the range is estimated based on the recent fuel economy. Therefore, the range reading may change as your driving habits change. Going from city to highway driving may increase the range reading. If the range display shows LO, you should stop for fuel as soon as possible. 2-78
