indicator system is duty-cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.
Unless reset, this message will continue to display each
time you turn the ignition switch to the ON position. To
turn off the message temporarily, press and release the
RETURN button. To reset the oil change indicator system
(after performing the scheduled maintenance) perform
the following steps.
1. Turn the ignition switch to the ON position. (Do not
start the engine)
2. Fully depress the accelerator pedal slowly three times
within 10 seconds.
3. Turn the ignition switch to the OFF position.
NOTE: If the indicator message illuminates when you
start the engine, the oil change indicator system did not
reset. If necessary, repeat these steps.
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 30 miles (48 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.
