2012 - climate control not really off when turned off?

2012 Mazda CX-9 Touring
Hey all,

We've had our CX-9 for about 2 months now. I have noticed in the last couple weeks that, if
we turn off the climate control (yes, we're driving), the display (on the upper dash) still shows that
its either on recirculate and blowing on the feet, or I can cycle thru different modes. In any of
those cases, it won't totally shut off even though I push the HVAC button to turn it off. The fan is
probably blowing at its slowest setting that I can tell (or not at all?). Is this normal for it to operate this way?
What's annoying about it is that you can't change the temperature, because you've switched off the main control.
And at least lately, since its been warm here (Ohio), the air coming in the vents is rather warm.

Is this similar to how VW does thier HVAC where its always on "vent"? At least with VW, you can move the
temp dial and partially affect the temp of the air coming in. Just seems odd that the CX-9 would default
to a recirc air setting. Not sure that it let me change to fresh air.

Curious to hear some thoughts on this.
 
I haven't tried this on my CX-9, but I suspect the air flow you feel is the air pressure while driving. I had an '84 Rabbit and it vented too while moving. Do you feel any air coming in when the car isn't moving?

The "off" position may just be the fan setting and it doesn't close the vent. If you felt any heat, it likely would have been using the last setting and how far open the heat exchange valve was open. With older mechanical slider settings for the heat, you could feel the heater core flap open and close as you moved the lever.
 
this is your vent, CX-9 is smart enough to set your vent air to whatever temp you have your air when you turned it off. i notice this when its 63 degrees outside and i have my air (when turned on ) set to 71 no air comes out. but when i turn on the air and adjust it down to 60 and turn if off the air blows in
