Instrument Cluster Distance to empty is calculated using a running average fuel economy, which is based on your recent driving history of 500 miles (800 km). This value is not the same as the average fuel economy display. The running average fuel economy is re-initialized to a factory default value if the battery is disconnected. AVG MPG (L/100km) Average fuel economy displays your average fuel economy in miles/gallon or liters/100 km. If you calculate your average fuel economy by dividing distance traveled by gallons of fuel used (liters of fuel used by 100 kilometers traveled), your figure may be different than displayed for the following reasons: • Your vehicle was not perfectly level during fill-up • Differences in the automatic shut-off points on the fuel pumps at service stations • Variations in top-off procedure from one fill-up to another • Rounding of the displayed values to the nearest 0.1 gallon (liter) To determine your average highway fuel economy, do the following: 1. Drive the vehicle at least 5 miles (8 km) with the speed control system engaged to display a stabilized average. 2. Record the highway fuel economy for future reference. It is important to press the SELECT/RESET stem (press and hold for two seconds in order to reset the function) after setting the speed control to get accurate highway fuel economy readings. XX°F / XX°C The outside air temperature is shown together with the compass heading in the bottom row of the message center display. Refer to Units in this section for information on selecting °F or °C. COMPASS DISPLAY (if equipped) The compass heading is displayed as one of N, NE, E, SE, S, SW, W and NW in the message center display. The compass reading may be affected when you drive near large buildings, bridges, power lines and powerful broadcast antenna. Magnetic or metallic objects placed in, on or near the vehicle may also affect compass accuracy. 20 2012 Expedition (exd) Owners Guide, 3rd Printing USA (fus)
