Fuel
. (Fuel): Press this button to access the Average
Fuel Economy, Instantaneous Fuel Economy, and Fuel
Range modes.
AVG ECONOMY (Average Fuel Economy): This
screen will display the approximate average miles per
gallon (mpg) or liters per 100 kilometers (L/100 km). This
number is calculated based on the number of mpg
(L/100 km) recorded since the last time this menu item
was reset.
To reset the average fuel economy for the vehicle,
follow this procedure:
1. Press the set/reset button to reset to zero.
2. Press the fuel button again to advance to the
next screen.
INST ECONOMY (Instantaneous Fuel
Economy): This screen displays the current fuel
economy at a particular moment and will change
frequently as driving conditions change. Unlike average
fuel economy, this screen cannot be reset.
Press the fuel button again to advance to the next
screen.
RANGE: This screen displays the approximate number
of remaining miles or kilometers the vehicle can be
driven without refueling. This estimate is based on the
average fuel economy for the amount of fuel remaining
in the fuel tank and the current driving conditions.
This estimate will change if driving conditions change.
For example, if driving in traffic and making frequent
stops, the display may read one number, but if the
vehicle is driven on a freeway the number may change
even though the same amount of fuel is in the fuel
tank. This is because different driving conditions produce
different fuel economies. Generally, freeway driving
produces better fuel economy than city driving.
If the fuel tank contains less than 2 gallons (7.6 L), the
LOW FUEL message will appear on the DIC screen.
Fill the fuel tank as soon as possible to avoid running
out of fuel. See “Low Fuel” under DIC Warnings
and Messages on page 3-72.
