current distance traveled since the last reset for
each trip odometer in either miles or kilometers.
Both odometers can be used at the same time.
Each trip odometer can be reset to zero separately
by pressing and holding the ENTER button for a
few seconds while the desired trip odometer is
displayed.

The fuel economy data used to determine fuel range is
an average of recent driving conditions. As your driving
conditions change, this data is gradually updated. Fuel
range cannot be reset.
ECON (Economy): Press the INFO button until ECON
appears in the display. Average fuel economy is how
many miles per gallon or liters per 100 kilometers
your vehicle is getting based on current and past driving
conditions.
Press and hold the ENTER button while ECON is
displayed to reset the average fuel economy. Average
fuel economy will then be calculated starting from
that point. If the average fuel economy is not reset,
it will be continually updated each time you drive.
AV (Average) SPEED: Press the INFO button until AV
SPEED appears in the display. This is the vehicle's
average speed in miles per hour or kilometers per hour.
Press and hold the ENTER button while AV SPEED
is displayed to reset the average vehicle speed.
OIL LIFE: Press the INFO button until OIL LIFE appears
in the display. The engine oil life system shows an
estimate of the oil's remaining useful life. It will show
100% when the system is reset after an oil change. It will
alert you to change your oil on a schedule consistent with
your driving conditions.
