Instruments and Controls 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. Instantaneous Consumption This display shows the current fuel economy at a particular moment and will change frequently as driving conditions change. This display shows the instantaneous fuel economy in miles per gallon (mpg) or liters per 100 kilometers (l/100 km). The metric display changes depending on speed: Average Speed 4-35 • Below 8 mph (13 km/h), displays in l/h. • Above 8 mph (13 km/h), displays in l/100 km. This screen cannot be reset. Distance Travelled This display shows the current distance traveled in either miles (mi) or kilometers (km) since the last reset. The measurement can be reset to zero at any time and restarted. See "Reset" later in this section. This display shows the average speed of the vehicle in miles per hour (mph) or kilometers per hour (km/h). This average is calculated based on the various vehicle speeds recorded since the last reset of this value. The measurement can be reset to zero at any time and restarted. See "Reset" later in this section. Trip Consumption This display shows the number of gallons (gal) or liters (l) of fuel used since the last reset. The measurement can be reset to zero at any time and restarted. See "Reset" later in this section.
