FORD 2008 F-550 v.4 - Manual (Page 122)

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 control switch (press and
hold for 2 seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
