Instrumentation INST ECONOMY Your instantaneous fuel economy is the fuel economy you get at any particular moment. For example, you can see what your fuel economy is in heavy traffic or on the highway. Factors such as braking, acceleration, and road terrain affect your fuel economy. To display instantaneous fuel economy, press the SELECT button until the menu displays INST ECONOMY. Your vehicle must be moving for the computer to calculate a fuel economy greater than zero. AVG ECONOMY The average fuel economy is an overall average of your fuel economy taken from the last time the reset button was pushed. The computer takes an average of all the types of driving you have done since the RESET button was pressed (highway, city, heavy traffic), and figures out the average fuel economy. You can calculate your average fuel economy as often as you like. For example, you can calculate the average fuel economy for each tank of fuel or for every day. 27
