Driver Controls The DTE function will display LOW FUEL LEVEL and sound a tone for one second when you have approximately 25 miles (40 km) to empty. If you RESET this warning message, this display and tone 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 reinitialized to a factory default value if the battery is disconnected. Average fuel economy (AFE) Select this function from the INFO menu to display your average fuel economy in liters/100 km or miles/U.S. gallon. If you calculate your average fuel economy by dividing gallons of fuel used by 100 miles traveled (kilometers traveled by liters used), 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 8 km (5 miles) 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 RESET control after setting the speed control to get accurate highway fuel economy readings. Distance to empty/Average fuel economy for FFV-equipped vehicles Upon refueling, your vehicle must determine the percentage of Ethanol in the fuel. Until the percent of Ethanol is determined, DTE/AFE may not display the current values. The correct DTE/AFE will appear after driving a few miles. 54 2007 Taurus (tau) Owners Guide (post-2002-fmt) USA (fus)
