On full auto the fan speed should adjust automatically. With the fresh air/recirculate on auto the system will choose automatically based on the quality of the outside air. The "exception" is when you get in the car when the interior temp is very high, such as when it has been sitting in the sun for a long time. In that case you need to manually select "Max". That will override the auto settings. Then when you turn off the Max setting it will return to the previous auto settings.
