Interior Air Quality System*
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
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.
Note
To maintain the CZIP standard in cars with CZIP, the IAQS filter must be changed after 15 000 km or once per year, depending on whichever occurs first. However, up to 75 000 km over 5 years.
In cars without CZIP and where the customer does not want to retain the CZIP standard, the IAQS filter must be changed during a normal service.
Activating/deactivating the air quality sensor
It is possible to set whether the air quality sensor should be activated/deactivated.
