Average Fuel Economy (AFE)
WARNING: This page is about a different car, the 2003 Buick Regal and 2003 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
AFE is calculated as the ratio between the following values:
- AFE=Distance/Fuel
- Distance=The accumulated distance since the last AFE reset
- Fuel=The accumulated fuel consumption since the last AFE reset
You can reset the AFE mode by depressing the RESET button for 1 second. The value of this mode is retained during ignition OFF.
