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.
Note
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.
