the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
This light should come on briefly as
the engine is started. If it does not

average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank.
Fuel Economy : The center
displays the approximate
instantaneous fuel economy as a
number and bar graph. Displayed
above the bar graph is a running
average of fuel economy for the
most recently traveled selected
distance. Displayed below the bar
graph is the best average fuel
economy that has been achieved for
the selected distance. The selected
distance is displayed at the top of
the page as “last xxx mi/km.”
Press

recent driving compares to the best
that has been achieved for the
selected distance.

the oil's remaining useful life.
If REMAINING OIL LIFE 99% is
displayed, that means 99% of the
current oil life remains.
When the remaining oil life is low,
the CHANGE ENGINE OIL SOON

turned off, it will be removed from
the list.
Economy Trend : Displays history
of the Average Fuel Economy from
the last 50 km (30 miles). Each bar
represents about 5 km (3 miles) of
driving. The fuel economy will range
from 0 –15 L/100 km (0 –50 mpg).
During driving the bars will shift to always reflect the most recent
distance on the right side. This
display cannot be reset.
ECO Index :
The bar graph
