Vehicle Data
Average Fuel Economy: Press the SELECT button
until the display shows AVG FUEL ECONOMY. Average
fuel economy is viewed as a long term approximation
of your overall driving conditions. To learn the average
fuel economy from a new starting point, press the
RESET button for five seconds while the average fuel
economy is displayed on the DIC.
Instantaneous Fuel Economy: Press the SELECT
button until the display shows INST FUEL ECONOMY.
Instantaneous fuel economy varies with your driving
conditions, such as acceleration, braking and the grade
of the road being traveled. The RESET button does
not function in this mode.
Fuel Range: Press the SELECT button until the display
shows FUEL RANGE. The fuel range will calculate
the remaining distance you can drive without refueling.
This calculation is based on the average fuel economy
for the last 25 miles (40.25 km) driven, and the fuel
remaining in the fuel tank. If the fuel range drops below
40 miles (64.4 km), the display will show FUEL
RANGE LOW. The RESET button does not function in
this mode.
Fuel Used: Press the SELECT button until the display
shows FUEL USED. The value indicates how much
fuel has been used since the last reset. Don't confuse
fuel used with the amount of fuel in your tank. To
learn how much fuel will be used from a specific starting
point, press the RESET button for five seconds while
the fuel used is displayed on the DIC.
