Av Vehicle Speed

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.

Average speed is calculated using the equation: Average Speed = Distance/Ignition On

Distance = The accumulated distance travelled since the last reset of this value
Ignition On = The accumulated ignition on time since the last reset of this value

Ignition on time is measured from the time that the ignition is turned ON to the time when the ignition is turned OFF. The value of this mode is retained during ignition OFF. Press and hold the SET/RESET button on the DIC for 1 second in order to reset the average speed display.
