Climate control
NOTE
Heating or cooling cannot be hastened by
selecting a higher/lower temperature than
the actual temperature required.
AC – Air conditioning on/off
The air conditioning is con-
trolled automatically by the
system when the ON lamp is
on. This way, incoming air is
04
sufficiently cooled and dehu-
midified.
When the OFF lamp is on, the air conditioning
is always disengaged. Other functions are still
controlled automatically. When defroster is
selected, the air conditioning system is set for
maximum dehumidification.
Defroster
Used to quickly remove mist-
ing and ice from the wind-
screen and side windows. Air
flowing to the windows. The
light in the defroster button
illuminates when the function
is active.

vide maximum dehumidification in the passen-
ger compartment:

•
the air conditioning is automatically
engaged
•
recirculation is automatically disengaged.
The air conditioning can be disengaged man-
ually using the AC button. When the defroster
function is switched off the climate control sys-
tem returns to the previous settings.
Recirculation/Air quality system
Recirculation
When recirculation is
engaged the right-hand
orange light in the button illu-
minates. The function is
selected to shut out bad air,
exhaust gases etc. from the
passenger compartment. The
air in the passenger compartment is recircula-
ted, i.e. no outside air is taken into the car when
this function is activated. If the air in the car
recirculates for too long, there is a risk of mist-
ing on the insides of the windows.
Timer
With the timer function activated the system
will exit manually activated recirculation mode
according to a time that depends on the out-
side temperature. This reduces the risk of ice,
misting and bad air. Activate/deactivate the
function under Climate settings
Recirculation timer. For a description of the
menu system, see page 116.
NOTE
When Defroster is selected, recirculation is
always deactivated.
Air quality system*
The air quality system sepa-
rates gases and particles to
reduce the levels of odours
and pollution in the passenger
compartment. If the outside
air is contaminated then the
air intake is closed and the air
is recirculated. 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.
