Fuel Data Display (Digital Cluster) The fuel data display tells you all you about the fuel economy and how far you can travel with the fuel remaining. To reset the average fuel economy, press the INFO button until the MPG AVG is displayed on the Driver Information Center (DIC). Press and hold the INFO RESET button until both the fuel data display and DIC display reads 0.0. 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. On the analog cluster, fuel data can be obtained by pressing the INFO button. See "Driver Information Center" in the Index. The average fuel economy (AVG) display shows the average miles per gallon. 2-95
