Selectable features
English/metric display

computer display between metric

Mode control
Each press of the MODE control will
display a different feature as follows:
Average fuel economy. The display
will indicate the vehicle's average
fuel economy in liters/100 km (or
miles/gallon) since the average fuel
economy was last reset.
If you calculate your average fuel
economy by dividing liters of fuel
used by 100 kilometers traveled
(miles traveled by gallons used), your figure may be different than
displayed for the following reasons:
• your vehicle was not perfectly level during fill-up
• differences in the automatic shut-off points on the fuel pumps at
service stations
• variations in top-off procedure from one fill-up to another
• rounding of the displayed values to the nearest liter (gallon)
To reset the average fuel economy:
1. Press the MODE control repeatedly until average fuel economy is
displayed (this is the only resettable display).
