WARNING: This page is about a different car, the 2004 Ford Pickup, 2004 Ford F550 Super Duty, 2004 Ford F450 Super Duty, 2004 Ford Excursion, and 2004 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

The AVG fuel economy display is resettable. To reset, the ignition switch must be in the RUN position (with or without the engine running) and the message center must be in the AVG fuel economy mode.
Press and hold both buttons while in AVG fuel economy mode for a period of two to three seconds until AVG is displayed. Release both buttons to reset AVG fuel economy.
If the vehicle is parked while resetting, the AVG fuel economy will display 99.9 (metric mode) or 0.0 (English mode).
