Average Speed

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

Average speed is calculated as the ratio between the following values:

Average Speed = Distance/Ignition On
Distance = Accumulated distance since last reset
Ignition On = Accumulated ignition on time since last reset, ignition on is defined as run power mode with engine RPM greater than 100.

Ignition On time is measured from the time that the ignition is turned ON to the time when the ignition is turned OFF.

You can reset the Average Speed mode by depressing and holding the Set button for more than 3 seconds. The value of this mode is retained during ignition OFF.
