Dodge 2008 Ram Pickup 3500 - Manual (Page 137)

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 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.
