The DTE function will flash for 5 seconds when you have approximately:
•50 miles (80 km) left before you run out of fuel
•25 miles (40 km )
•10 miles (16 km)

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.
