IAQS is a part of the Clean Zone Interior Package (CZIP) and cleans the air in the passenger compartment from contaminants such as particles, hydrocarbons, nitrous oxides and ground-level ozone.
If the air quality sensor senses that the outside air is contaminated, the air intake is closed and air recirculation is activated.
The air quality sensor must always be enabled to ensure the best air in the passenger compartment.
In a cold climate recirculation is limited so as to prevent misting.
In the event of misting, the defrost functions for windscreen, side windows and rear window should be used.
