FUEL RANGE This display shows the approximate number of remaining miles (mi) or kilometers (km) you can drive without refilling your fuel tank. This estimate is based on the current driving conditions and will change 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 approximately 40 miles (64 km) remaining, the display will show FUEL RANGE LOW. If your vehicle is low on fuel, the FUEL LEVEL LOW message will be displayed. See "FUEL LEVEL LOW" under DIC Warnings and Messages on page 3-76 for more information. INST (Instantaneous) ECONOMY (IFE) 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 will change frequently as driving conditions change. Unlike average economy, this display cannot be reset. FUEL USED This display shows the number of gallons (gal) or liters (L) of fuel used since the last reset of this display. To reset this display, press the set/reset button. The display will return to zero. TIMER ON/OFF 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 00:00:00 TIMER OFF displays. To turn on the timer, press the set/reset button until TIMER ON displays. The timer will then start. To turn off the timer, press the set/reset button again until TIMER OFF displays. The timer will stop and display the end timing value. To reset the timer, press and hold the set/reset button after the timer has been stopped. The display will return to zero. 3-73 AVERAGE ECONOMY (AFE) 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, press the set/reset button. The display will return to zero.
