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 miles/gallon or
liters/100 km.

If you calculate your average fuel
economy by dividing distance 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)
To determine your average highway fuel economy, do the following:

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 RESET (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.

For more information refer to Essentials of good fuel economy in the
Maintenance and Specifications chapter.

Instantaneous fuel economy (IFE)

Select this function from the INFO
menu to display your instantaneous
fuel economy. This will display your
fuel economy as a bar graph ranging
from

poor economy to

excellent economy.
