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 XXX MILES TO E FUEL LEVEL
LOW
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 after 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 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 2
seconds in order to reset the function) after setting the speed control to
get accurate highway fuel economy readings.
