    I don't know if it's a problem or not, but on my 2011 prius II, when i turn the a/c off, with everything off, all the lights are off except for the recirculated air mode on. I still feel air coming through, a little. I don't want any air to go through at all. When i turn off recirculated air mode off, a little air go in but not much. Usually, i don't want to rely on the A/C, so i turn everything off, even the fan is off, also, I don't want the air from outside to go in, but it still go in. I don't know if there's a problem in the prius. Sorry for the english.

    A simple line would be, with everything off, A/C off, fan off, recirculated air mode on, still air still manage to go in. I don't know if it's outside or engine air.. I just don't know..

    It's not a problem. It's designed that way on purpose. It's a legal requirement so you don't sit in your car and suffocate because of a lack of fresh air. If everything is off, then you aren't using the A/C.

    So if you saying that it's legal requirement to let the fresh air in, what happen if you don't want to smell the farm fertilizer on the freeway. how do you block that air from coming in with everything off?

    Hit the "air freshener" button right next too it. It works great for skunks, diesels, etc. :rockon:

    Another reason that you always want air flow coming in is to keep your HV battery cool. The cabin air is pulled across the batteries to cool and then exhausted outside the car.

    That is why even the "air freshener" has a 3 minute timer. That and not fogging up your windshield.
