Av Fuel Econ

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

Average fuel economy is calculated using the equation: AFE = Distance/Fuel

Distance = The accumulated distance travelled since the last reset of this value
Fuel = The accumulated fuel consumption since the last reset of this value

The DIC receives a serial data message from the body control module (BCM) regarding fuel usage information. The value of this mode is retained during ignition OFF and can be changed between English units and metric units. Press and hold the SET/RESET button on the DIC switch for 1 second in order to reset the ECON display.
