Driver Controls Average fuel economy for FFV-equipped vehicles Upon refueling, your vehicle must determine the percentage of Ethanol in the fuel. For the first several minutes, or few miles of driving, the message "COMPUTING FUEL" or will appear in the message center. The correct fuel economy will appear within approximately five miles of driving. Trip elapsed drive time Select this function from the INFO menu to display a timer.

Press and hold RESET for 2 seconds in order to reset the timer. Distance to empty (DTE) Selecting this function from the INFO menu estimates approximately how far you can drive with the fuel remaining in your tank under normal driving conditions. Remember to turn the ignition OFF when refueling to allow this feature to correctly detect the added fuel. The DTE function will display LOW FUEL LEVEL and sound a tone for one second when you have approximately 80 km (50 miles) to empty. If you RESET this warning message, this display and tone will return within 10 minutes. DTE is calculated using a running average fuel economy, which is based on your recent driving history of 800 km (500miles). This value is not the same as the average fuel economy display. The running average fuel economy is reinitialized to a factory default value if the battery is disconnected. 66 2004 Mountaineer (mnt) Owners Guide (post-2002-fmt) USA English (fus)
