Average Fuel Economy

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 ECM sends the cumulative fuel usage information average fuel economy to the IPC. The instrument panel cluster (IPC) receives serial data message from the ECM regarding fuel usage information. The value of this mode is retained during ignition OFF and can be changed between English units and metric units by selecting English or Metric unit from the driver information center (DIC).
