FORD 2007 Expedition v.2 - Manual (Page 115)

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 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 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 stem system
engaged to display a stabilized average.
2. Record the highway fuel economy for future reference.
It is important to press the RESET stem (press and hold for 2 seconds in
order to reset the function) after setting the speed control to get
accurate highway fuel economy readings.
