6 Instrumentation AVERAGE ECONOMY Your average fuel economy is the average value of your fuel economy since the last reset. To display your average fuel economy, press SELECT until the pointer is at AVERAGE ECONOMY. The fuel computer calculates average fuel economy from the distance traveled and the fuel used (as reported by the Electronic Engine Control module). Press the RESET button when AVERAGE ECONOMY is selected to reset the average fuel economy. You may want to use this feature to see how your fuel economy changes each day or for each tank of fuel. If you calculate your fuel economy based on the odometer distance traveled and the amount of fuel you pump into the tank, your number may be different than the fuel computer number for various reasons. Most likely, the top level of fuel added may be different between fill-ups, causing an incorrect estimate of the amount of fuel used. DISTANCE TO EMPTY Your distance to empty is the approximate number of miles or kilometers that you can drive before you run out of fuel. To display your distance to empty, press SELECT until the pointer is at DISTANCE TO EMPTY. The fuel computer calculates distance to empty from the amount of fuel in the tank and an internally determined fuel economy value, which is not the same as the AVERAGE ECONOMY number. DISTANCE TO EMPTY is not resettable. You may want to use this feature to plan when your next fuel fill-up should be. Your distance to empty may change faster or slower than actual distance traveled because your fuel economy varies with changing driving conditions. 35
