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.
