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 118.
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.
