For example, if the vehicle was driven 8 km (5 mi) before it is started again, and then the retroactive reset feature is activated, the display will show 8 km (5 mi). As the vehicle begins moving, the display will then increase to 8.2 km (5.1 mi), 8.4 km (5.2 mi), etc. If the retroactive reset feature is activated after the vehicle is started, but before it begins moving, the display will show the number of kilometers (km) or miles (mi) driven during the last ignition cycle.


RANGE Press the trip/fuel button until RANGE displays. This display shows the approximate number of remaining kilometers (km) or miles (mi) the vehicle can be driven without refueling. The display will show LOW if the fuel level is low. The fuel range estimate is based on an average of the vehicle's fuel economy over recent driving history


and the amount of fuel remaining in the fuel tank. This estimate will change if driving conditions change. For example, if driving in traffic and making frequent stops, this 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. Fuel range cannot be reset.


AVG (Average) ECONOMY Press the trip/fuel button until AVG ECONOMY displays. This display shows the approximate average liters per 100 kilometers (L/100 km) or miles per gallon (mpg). This number reflects only the approximate average fuel economy that the vehicle has right now, and will change as driving conditions change. This number is calculated based on the number of L/100 km (mpg) recorded since the last time
