Average fuel economy (AFE)
Select this function from the INFO
menu to display your average fuel
economy in miles/gallon or
liters/100 km.
If you calculate your average fuel
economy by dividing 100 miles
traveled by gallons of fuel used (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 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 RESET control (press and hold RESET for
two seconds in order to reset the function) after setting the speed
control to get accurate highway fuel economy readings.
