Average Fuel Economy (Afe); Distance To Empty/Average Fuel Economy For Ffv-Equipped Vehicles - Ford Taurus Owner's Manual

Driver Controls
The DTE function will display LOW FUEL LEVEL and sound a tone for
one second when you have approximately 50 miles (80 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.
