Fuel Menu Items (Uplevel Only)
.
(Fuel):Press this button to scroll through the
following menu items:
Fuel Range
Press the fuel button until FUEL RANGE displays. This
mode shows the approximate number of remaining
miles or kilometers the vehicle can be driven without
refueling.
Fuel range is based on several factors, including
distance traveled, fuel used, fuel capacity, etc. This
estimate will change if driving conditions change. For
example, if driving in traffic and making frequent
stops, this mode 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.
Fuel range cannot be reset.
If your vehicle is low on fuel, FUEL RANGE LOW will
display followed by the LOW FUEL message. See “LOW
FUEL” underDIC Warnings and Messages on
page 3-58for more information.
Average Fuel Economy
Press the fuel button until AVG ECONOMY displays.
This mode shows 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

was reset. To reset AVG ECONOMY, press and hold the
