Ambient Air Quality Sensor (if equipped)

WARNING: This page is about a different variant/trim than selected.

The ambient air quality sensor contains a sensing element which measures substances in the ambient air such as petrol and/or diesel fumes. The ambient air quality sensor is an input to the FCIM and the information is evaluated by the FCIM. The A/C system is actuated depending on the degree and manner of ambient air pollution. Depending on a combination of both lower or higher ambient temperature and/or pollution the recirculation system will operate. When the pollution concentration decreases, the air conditioning system is switched back to the fresh air mode.
