The example I was given was in the winter time, if you have the heat on your feet or windhshield, keep the knob on blue and it'll take air from the outside and blow through the front vents.

Not be to be confused with the re-circulate button
nope, knob is for face vents temps only. In winter time, I put the knob on middle setting or on cold but still turn up the heat with the climate control knobs.
