Range

The range displayed is an estimate of the expected remaining driving distance with the current fuel level. The vehicle driving range is based on the fuel remaining in the tank and the fuel economy over the last 40 km (25 mi). Since the calculated range parameter is an estimated value, the displayed value and the actual vehicle range may vary. When the calculated range parameter falls below 65 km (40 mi), the range displayed is LO. The range parameter is calculated by the IPC using the following formula:

(Estimated Range) = (Distance Traveled) I (Fuel Used) x (Scale Factor) x (Filtered Fuel in Tank)

This calculation may not be reset by the driver. The data used in order to calculate the range parameter is lost if a battery disconnect occurs. The range display contains dashes if the IPC is unable to communicate with the PCM or PZM via the class 2 serial data line.
