Interior Air Quality System (IAQS)
*
The Interior Air Quality System uses a multifilter
and an air quality sensor to remove gases, parti-
cles and other contaminants from the air enter-
ing the passenger compartment.
The IAQS air quality sensor monitors increased
levels of contaminants in the outside air and if
contaminants are detected, the air intake closes
and the air inside the passenger compartment is
recirculated, i.e., no outside air enters the vehicle.
The filter also cleans recirculated passenger
compartment air.
•
The air quality sensor should always be
engaged in order to obtain the best air in
the passenger compartment.
•
Recirculation is limited in cold weather to
avoid fogging.
•
If the insides of the windows start fog-
ging, disengage the air quality sensor.
Use the defroster function to increase
airflow to the front, side, and rear win-
dows.

vation:

dusty or industrial areas, the filer may need to be
replaced more often. Consult your Volvo retailer.
