Remember to turn the ignition OFF when refueling your vehicle.
Otherwise, the display will not show the addition of fuel for a few miles.
At least four gallons of fuel must be added for the fuel gauge to
immediately show the new fuel level.
The DTE function will flash for 5 seconds and sound a tone for 1 second
when you have approximately:
²80 km (50 miles) left before you run out of fuel
²40 km (25 miles)
²16 km (10 miles)
The message center will remain in
the DTE function until the SELECT
control is pressed to change
functions.
Displayed DTE will not be equal to
AVG ECON multiplied by the FUEL
REMAIN value. DTE is calculated
using a method that considers the
fuel economy of the last 800 km
(500 miles) driven.
If ªCOº or ªCSº is displayed, there is a problem with the fuel indication
system and you should contact your dealer for service as soon as
possible.
AVG FUEL ECONOMY (average fuel economy)
Select this function to display your
average fuel economy in liters/100
km or miles/gallon.
If you calculate your average fuel
economy by dividing miles traveled by gallons used, your figure may be
different than displayed for the following reasons:
²your vehicle was not perfectly level during fill-up
²differences in the automatic shut-off points on the fuel pumps at
service stations
²variations in top-off procedure from one fill-up to another
²rounding of the displayed values to the nearest 0.1 liter (gallons)
