Perform compass calibration in an open area free from steel structures
and high voltage lines. For optimum calibration, turn off all electrical
accessories (heater/air conditioning, wipers, etc.) and make sure all
vehicle doors are shut.

the compass calibration function.
9. Slowly drive the vehicle in a
circle (less than 5 km/h [3 mph])

up to five circles to complete calibration.
10. The compass is now calibrated.
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 LOW FUEL LEVEL and sound a tone for
one second when you have approximately 80 km (50 miles) to empty. If
you RESET this warning message, this display and tone will return
within 10 minutes.
DTE is calculated using a running average fuel economy, which is based
on your recent driving history of 800 km (500miles). 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.
