Vehicle Data Average Fuel Economy: Press the SELECT button until the display shows AVG FUEL ECONOMY. Average fuel economy is viewed as a long term approximation of your overall driving conditions. To learn the average fuel economy from a new starting point, press the RESET button for five seconds while the average fuel economy is displayed on the DIC. Instantaneous Fuel Economy: Press the SELECT button until the display shows INST FUEL ECONOMY. Instantaneous fuel economy varies with your driving conditions, such as acceleration, braking and the grade of the road being traveled. The RESET button does not function in this mode. Fuel Range: Press the SELECT button until the display shows FUEL RANGE. The fuel range will calculate the remaining distance you can drive without refueling. This calculation is based on the average fuel economy for the last 25 miles (40.25 km) driven, and the fuel remaining in the fuel tank. If the fuel range drops below 40 miles (64.4 km), the display will show FUEL RANGE LOW. The RESET button does not function in this mode. Fuel Used: Press the SELECT button until the display shows FUEL USED. The value indicates how much fuel has been used since the last reset. Don't confuse fuel used with the amount of fuel in your tank. To learn how much fuel will be used from a specific starting point, press the RESET button for five seconds while the fuel used is displayed on the DIC. Battery Volts: On vehicles with a supercharged engine, press the SELECT button until the display shows BATTERY VOLTS. If the voltage is normal the display will show BATTERY ## VOLTS. If the voltage drops below 10.5 volts for 30 seconds, the battery volts display will show BATTERY LOW. If the voltage is above 16.2 volts for 30 seconds, the battery volts display will show BATTERY HIGH. If the display shows the high or low message, you need to have your battery and/or electrical system checked. 2-91
