will appear whenever the Multi-Displacement System
(MDS) (if equipped) allows the engine to operate on four
cylinders, or if you are driving in a fuel efficient manner.
This feature allows you to monitor when you are driving
in a fuel efficient manner, and it can be used to modify
driving habits in order to increase fuel economy.
Distance To Empty (DTE)
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 a weighted
average of the instantaneous and average fuel economy,
according to the current fuel tank level. DTE cannot be
reset through the RETURN button.
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 10 miles (16 km)
estimated driving distance, the DTE display will change
to a text display of
ЉLOW FUEL.Љ This display will
continue until the vehicle runs out of fuel. Adding a
significant amount of fuel to the vehicle will turn off the
ЉLOW FUELЉ text and a new DTE value will display.
