Fuel Menu Items (Uplevel Only) . (Fuel): Press this button to scroll through the following menu items: 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 (L/100 km) recorded since the last time this menu item was reset. To reset AVG ECONOMY, press and hold the set/reset button. The display will return to zero. 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 travelled, 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" under DIC Warnings and Messages on page 3-53 for more information. Instantaneous Fuel Economy Press the fuel button until INST ECONOMY displays. This mode shows the current fuel economy at a particular moment and will change frequently as driving conditions change. This mode shows the instantaneous fuel economy in miles per gallon (mpg) or liters per 100 kilometers (L/100 km). Unlike average fuel economy, this screen cannot be reset. Gages Menu Items (Uplevel Only) 2 (Gages): Press this button to scroll through the following menu items: Battery Press the gages button until BATTERY displays.
