I don't know if this has been mentioned. But I find if I turn the fan off as I come to a stop that I can coax Auto-stop at much colder external temperatures that would normaly be possible.

Normaly autostop doesn't work if the temp is <40F aprox. Using this technique the auto-stop has reported to have kicked in at temps as low as 4F. Once the car is autostoped you can turn the fan back on. However, since the engine isn't running the air starts to slowly come out of the vents cooler (not cold just cooler).

I have an 03' CVT. Not sure if the trick works on other models.
