Driver Controls Distance to empty (DTE) Selecting this function from the INFO MENU estimates approximately how far you can drive with the fuel remaining in your tank under normal driving conditions. Remember to turn the ignition off when refueling to allow this feature to correctly detect the added fuel. The DTE function will display XXX MILES TO E FUEL LEVEL LOW and sound a chime for one second when you have approximately 50 miles (80 km) to empty. If you RESET this warning message, this display and chime will return within 10 minutes. DTE is calculated using a running average fuel economy, which is based on your recent driving history of 500 miles (800 km). This value is not the same as the average fuel economy display. The running average fuel economy is re-initialized to a factory default value if the battery is disconnected. Average fuel economy (AFE) Select this function to display your average fuel economy in miles/gallon or liters/km. If you calculate your average fuel economy by dividing miles traveled by gallons of fuel used (liters of fuel used by 100 kilometers traveled), your figure may be different than displayed for the following reasons: • Your vehicle was not perfectly level during fill-up • Differences in the automatic shut-off points on the fuel pumps at service stations • Variations in top-off procedure from one fill-up to another • Rounding of the displayed values to the nearest 0.1 gallon (liter) 1. Drive the vehicle at least 5 miles (8 km) with the speed control system engaged to display a stabilized average. 2. Record the highway fuel economy for future reference. It is important to press the SELECT/RESET stem (press and hold for two seconds in order to reset the function) after setting the speed control to get accurate highway fuel economy readings. 72 2009 Econoline (eco) Owners Guide, 2nd Printing USA (fus)
