Instantaneous Fuel Economy (IFE)

WARNING: This page is about a different car, the 2009 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.

IFE is calculated using the equation: IFE = Distance/Fuel Used.

The IPC receives a serial data message from the ECM. The distance information is calculated by the IPC using the vehicle speed information from the ECM. These values are retained during ignition OFF and can be changed between English and Metric units by accessing the DIC trip/fuel information switch. The IFE display cannot be reset.
