The Average Fuel Economy can be
reset by pressing SET while the
Average Fuel Economy display is
showing.
The Instantaneous Fuel Economy
display shows the current fuel
economy in either liters per
100 kilometers (L/100 km) or miles
per gallon (mpg). This number
reflects only the fuel economy
that the vehicle has right now and
changes frequently as driving
conditions change. Unlike average
economy, this display cannot be
reset.
Fuel Range
The Fuel Range display shows the
approximate distance the vehicle
can be driven without refueling.
The fuel range estimate is based on
an average of the vehicle's fuel
economy over recent driving history
and the amount of fuel remaining in
the fuel tank. Fuel range cannot be
reset.
Fuel Used
The Fuel Used display shows
the approximate gallons (gal) or
liters (L) of fuel that has been used

be reset by pressing the SET button
while the Fuel Used display is
showing.
Average Vehicle Speed
The Average Vehicle Speed display
shows the average speed of the
vehicle in miles per hour (mph) or
kilometers per hour (km/h). This
average is calculated based on the
various vehicle speeds recorded
since the last reset of this value.
The average speed can be reset by
pressing the SET button while the
Average Vehicle Speed display is
showing.
Elapsed Time
This display can be used as a timer.
To start the timer, press SET while
