Range

The vehicle range displays as an estimate of the expected remaining driving distance using the current fuel level. The driving range is based on the following conditions:
^ The fuel in the tank.
^ The fuel economy of the last 25 miles.

Because of the required predictions, the following messages may vary from each other:
^ The displayed range
^ The actual range

When the calculated range falls below 40 miles, the range display will read LOW.

The vehicle range is calculated by the instrument cluster.

The calculation for the Vehicle Range is Estimated Drivable Range = Distance Traveled/Fuel Used x Scale factor X Filtered Fuel in Tank.

The calculation is based on the last 25 miles. The calculation is an estimate of the drivable range. The calculation may not be reset by the driver. the data used in order to calibrate the range is lost if the battery is disconnected. This portion of the instrument cluster will be dashed if there is a loss of power to the Powertrain Control Module (PCM).
