Defroster
Used to quickly remove
misting and ice from the
windscreen and side win-
dows. Air flows to the win-
dows at high fan speed.
The light in the defroster
button illuminates when the
function is active.
The following also takes place in order to
provide maximum dehumidification in the
passenger compartment:
• the air conditioning (A/C) is engaged auto-
matically
• recirculation is automatically disengaged.
When the defroster function is switched off
the climate control system returns to the pre-
vious settings.
Recirculation/Air quality system
Recirculation
When recirculation is en-
gaged the right-hand or-
ange light in the button illu-
minates. The function is se-
lected to shut out bad air,
exhaust gases etc. from the
passenger compartment.
The air in the passenger compartment is re-
circulated, 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 misting 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 outside temperature. This reduces the
risk of ice, misting and bad air. Activate/de-
activate the function under
Climate control
settings Recirculation timer . For a de-
scription of the menu system, see page 94.
Air quality system*
The air quality system sepa-
rates gases and particles to
reduce the levels of odours
and pollution in the passen-
ger 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
button repeatedly.
• The left-hand orange lamp illuminates –
the air quality sensor is disengaged.
• The centre green lamp illuminates – recir-
culation not engaged, providing it is not
required for cooling in hot weather.
• The right-hand orange lamp illuminates –
recirculation is engaged.

NOTE
When Defroster is selected, recirculation is
always deactivated.
8704345s
NOTE
The air quality sensor should always be en-
gaged in order to obtain the best air in the
passenger compartment.
Recirculation is limited in cold weather to
avoid misting.
If the insides of the windows start misting
up, disengage the air quality sensor, and
the defroster function for the front, side and
rear windows should also be used to demist
the windows.
