Instantaneous Economy and Active Fuel Management™ Indicator

If the vehicle has this display, press the trip/fuel button until INST ECON V8 displays. This display shows the current fuel economy at a particular moment and will change frequently as driving conditions change. This display shows the instantaneous fuel economy in liters per 100 kilometers (L/100 km) or miles per gallon (mpg). Unlike average economy, this screen cannot be reset.

An Active Fuel Management indicator displays on the right side of the DIC, while INST ECON displays on the left side. Active Fuel Management allows the engine to operate on either four or eight cylinders, depending on driving demands. When Active Fuel Management is active, V4 will display on the DIC. When Active Fuel Management is inactive, V8 will display. See Active Fuel Management® on page 9‑35 for more information.
