Interior Air Quality System–IAQS*
This system consists of a mul-
tifilter and an air quality sen-
sor. The filter helps remove
gases and particles from the
incoming air, thereby reduc-
ing the amounts of odors and
contaminants entering the
vehicle. The air quality sensor detects
increased levels of contaminants in the outside
air. When the air quality sensor detects conta-
minated outside air, the air intake closes and
the air inside the passenger compartment is
recirculated, i.e., no outside air enters the vehi-
cle. The filter also cleans recirculated passen-
ger compartment air. When the AUTO button
is depressed the air quality sensor is always
engaged.
Activating the air quality sensor
Switch between the three
functions by pressing the but-
ton repeatedly.
•
The left orange light comes on – the air
quality sensor is disengaged.
•
The center green light comes on – recircu-
lation not engaged, providing it is not
required for cooling in hot weather.
•
The right orange light comes on – recircu-
lation is engaged.
04 Comfort and driving pleasure
NOTE
•
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.
