Auto A/C Recirc When Pollutants Sensed

I would like to accurately understand the exact function of the A/C recirc button.

When the left light is lit the manual (2011, P104) states " ... a sensor detects pollutants in the outside air and controls the shut-off automatically.". I interpret this as meaning a sensor will force it into recirc mode when it detects some sort of pollution. Exactly what is it sensing with respect to "pollutants" and how does it do this?

I assume auto mode also just allows the logic to switch to recirc mode when the outside air temp is too high for efficient cabin cooling. But, this statement in the manual strongly implies that the system will only go into recirc when it senses "pollutants".
