Dodge 2007 Ram Pickup 3500 - Manual (Page 182)

Average Fuel Economy (AVG ECO)
Shows the average fuel economy since the last reset.
Average fuel economy is a running average of the
amount of fuel used and the distance the vehicle has
traveled.
When the fuel economy is reset, the display will momen-
tarily blank. Then, the history information will be erased,
and the averaging will continue from where it was before
the reset. The reset value is based on a minimal amount
of fuel used and the distance traveled from the previous
drive cycle. The display may take several miles for this
value to change dependent upon driving habits.
Distance To Empty (DTE)
Shows the estimated distance that can be traveled with
the fuel remaining in the tank. This estimated distance is
determined by weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettable
NOTE: Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles estimated
driving distance, the DTE display will change to an
alternating test display of “LO” and “FUEL”. This dis-
play will continue until the vehicle runs out of fuel.
Adding a significant amount of fuel to the vehicle will
turn off the “LO FUEL” text and a new DTE value will be
displayed, based on the current values in the DTE
calculation and the current fuel tank level.
NOTE: It is possible for DTE to display “LO FUEL”
before the low fuel warning light turns on in the instru-
ment cluster. This could occur because low fuel warning
is set to a specified fuel tank volume and DTE is an
estimated distance calculation based on fuel economy
and remaining fuel tank volume.
