Does anyone else have airflow come out of their vents at times when your climate control system is completely off, especially when your moonroof is tilted open or maybe if its just hot/stuffy in the car? The airflow I am getting is almost like having the fan speed on the 2nd or 3rd speed.

Was this an intended "feature?" If so, is it pulling the air in or is the fan being signaled to turn on?

The manual also doesn't explain anything about the sunlight sensor and what it does....could this have anything to do with it?
