Interior Air Quality System
Interior Air Quality System (IAQS) is a fully automatic air quality system that removes gases and particles to reduce odors and contaminants in the passenger compartment.
IAQS is part of the Clean Zone Interior Package (CZIP) and removes air contaminants such as particles, hydrocarbons, nitric oxides and ground-level ozone.
If the system's air quality sensors detect contaminants in the outside air, the air intake closes and air recirculation is activated.
Note
Recirculation is limited in cold weather to prevent fogging.
In the event of fogging, use the defroster functions for the windshield, side windows and rear window.
