Instruments and Controls Fuel Range This display shows the approximate number of remaining miles (mi) or kilometers (km) you can drive without refilling the fuel tank. This estimate is based on the current driving conditions and changes if the driving conditions change. For example, if you are driving in traffic and making frequent stops, the display may read one number, but if you enter the freeway, the number may change even though you still have the same amount of fuel in the fuel tank. This is because different driving conditions produce different fuel economies. Generally, freeway driving produces better fuel economy than city driving. Once the range drops below about 30 miles (48 km) remaining, the display shows Low Range. If the vehicle is low on fuel, the Fuel Level Low message displays. See "Fuel Level Low" under Fuel System Messages on page 4‑42 for more information. AVG (Average) Economy This display 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 display was reset. To reset this display to zero, press the set/reset button. Timer This display can be used like a stopwatch. You can record the time it takes to travel from one point to another. To access the timer, press the trip/fuel button until Timer 00:00:00 displays. To turn on the timer, press the set/reset button until the timer starts. To turn off the timer, press the set/reset button again. The timer stops and displays the end timing value. 4-33 To reset the timer to zero, press and hold the set/reset button after the timer has been stopped. Inst (Instantaneous) Economy This display shows the current fuel economy in either miles per gallon (mpg) or liters per 100 kilometers (L/100 km). This number reflects only the fuel economy that the vehicle has right now and changes frequently as driving conditions change. Unlike average economy, this display cannot be reset. AVG (Average) Speed This display shows the average speed of the vehicle in either 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 display. To reset this display to zero, press the set/reset button.
