Instantaneous Fuel Economy (IFE)
WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
Instantaneous fuel economy is calculated as the ratio between the following values:
- IFE = Distance/Fuel
- Distance = The accumulated distance since last update
- Fuel = The accumulated fuel delivered since last update
You cannot reset the IFE mode. The value of this mode is retained during ignition OFF.
