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 func-
tion is selected by automatically switching off
the function after a certain length of time,
depending on the ambient temperature. Acti-
vate/deactivate the function under

Interior Air Quality System–IAQS
(option)
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 con-
taminants entering the vehicle. The air quality
sensor detects increased levels of contami-
nants in the outside air. When the air quality
sensor detects contaminated outside air, the
air intake closes and the air inside the pas-
senger compartment is recirculated, i.e., no
outside air enters the vehicle. The filter also
cleans recirculated passenger compartment
air. When the AUTO button is depressed the
air quality sensor is always engaged.

ging, disengage the air quality sensor. Use
the defroster function to increase airflow to
