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.
NOTE
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 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 120.
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 recirculation/air quality
sensor
Switch between the three
functions by pressing the but-
ton repeatedly.
04 Comfort and driving pleasure
•
The left-hand orange lamp illuminates – the
air quality sensor is disengaged. There is
no recirculation, only fresh air.
•
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
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 misting.
If the insides of the windows start misting
up, disengage the air quality sensor, and the
defroster functions for the windscreen, the
side and the rear windows should also be
used to demist the windows.
