FORD 1999 F-350 - Manual (Page 18)

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 0.1 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).
2. Press the E/M and MODE
controls simultaneously. The display
will illuminate the “AVG” indicator.
While the indicator is lit, release
both controls to reset the average
fuel economy.
Fuel range. This displays the approximate number of kilometers (miles)
left to drive before the fuel tank is empty. The indicated distance to
empty may be inaccurate:
• with sustained, drastic changes in fuel economy (such as trailer
towing), but will eventually recover.
