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. The
FUEL RANGE mode cannot be reset.
MPG (L/100 KM) AVG (Average)
Press the information button until MPG (L/100 KM) AVG
displays. This mode shows how many miles per gallon
(mpg) or liters per 100 kilometers (L/100 km) your
vehicle is getting based on current and past driving
conditions.
To reset the average fuel economy, press and hold the
reset button while MPG (L/100 KM) AVG is displayed.
Average fuel economy is then calculated starting from
that point. If the average fuel economy is not reset, it is
continually updated each time you drive.
MPG (L/100 KM) INST (Instantaneous)
Press the information button until MPG (L/100 KM) INST
displays. This mode shows the current fuel economy at
a particular moment and changes frequently as driving
conditions change. This mode shows the instantaneous

In addition to the engine oil life system monitoring the
oil life, additional maintenance is recommended in the
Maintenance Schedule in this manual. See Engine Oil
on page 6 16 and Scheduled Maintenance on
