The climate system will return to its previous
settings when the defroster function is
switched off.
Recirculation/air quality system
Recirculation
This function can be used to
shut out exhaust fumes,
smoke, etc., from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e., no air
from outside the car is taken
into the car when this function is activated. The
indicator light in the button will illuminate when
recirculation is selected.
If the air in the car recirculates for too long,
there is a risk of condensation forming on the
insides of the windows, especially in winter.
Timer
The timer function minimizes the risk of fog-
ging, or stale air when the recirculation function
is selected by automatically switching off the
function after a certain length of time, depend-
ing on the ambient temperature. Activate/
deactivate the function under
Climate
settings Recirculation timer . See page
133 for a description of the menu system.
NOTE
When Defroster is selected, recirculation is
always deactivated.
Interior Air Quality System–IAQS*
This system consists of a multifilter and an air
quality sensor. The filter helps remove gases
and particles from the incoming air, thereby
reducing the amounts of odors and contami-
nants entering the vehicle. The air quality sen-
sor detects increased levels of contaminants in
the outside air. When the air quality sensor
detects contaminated outside air, the air intake
closes and the air inside the passenger com-
partment is recirculated, i.e., no outside air
enters the vehicle. The filter also cleans recir-
culated passenger compartment air. When the
AUTO button is depressed the air quality sen-
sor is always engaged.
Activate or deactivate this function in Climate
settings Interior air quality system .
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.
