Air cleaning - IAQS*
If the outside air is contaminated then the air intake is closed and the air is recirculated.
It is possible to activate/deactivate the function in the menu system MY CAR. For a description of the menu system, see MY CAR.
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 air quality sensor should be disengaged, and the defroster functions for the windscreen and side windows, as well as the rear window, should be used.
To keep 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 keep the CZIP standard the IAQS filter must be changed at a regular service.
