INST ECON - Instantaneous Fuel Economy Select this function to calculate your instantaneous fuel 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 an open highway. Your vehicle must be moving to calculate fuel economy. When your vehicle is not moving, instantaneous fuel economy is displayed at 0 miles per gallon or 99 liters per 100 kilometers. When you are moving, the display may read anything between 0 and 99 miles/gallon (1 to 99 L/km). Instantaneous fuel economy cannot be reset. TRIP A and TRIP B - Elapsed Distance Traveled These two functions of the message center allow you to see how far you have traveled since you last reset. Trip A and Trip B are completely independent and must be reset individually. 36
