Note
Food, medicine and other heat or cold sen-
sitive objects should never be placed in
front of the air outlets as they may be dam-
aged or made unsuitable for use by the air.
Air recirculation
Air recirculation mode prevents the ambient
air from entering the interior.
For safety reasons, air recirculation is switch-
ed off in the following situations:
●
When the button
is pressed or the
air distributor is turned to
.
●
When a sensor detects that the vehicle's
windows could mist up.
Switching the manual air recirculation
mode on and off
●
Press the button
to connect or discon-
nect manual air recirculation.
Climatronic automatic air recirculation
mode
With the automatic air recirculation mode
activated, the entry of fresh air into the cabin
interior is enabled. If the system detects a
high concentration of hazardous substances
in the ambient air, air recirculation mode is
switched on automatically. When the level of
impurities drops to within a normal range, re-
circulation mode is switched off.
The system is unable to detect unpleasant
smells.
The air recirculation will not connect auto-
matically in versions without humidity sensor
and in the following external conditions:
●
The outside temperature is lower than +3°C
(+38°F).
●
The cooling system is switched off and the
outside temperature is below +10°C (+50°F).
●
The cooling system is switched off, the
outside temperature is below +15°C (+59°F)
and the windscreen wipers are switched on.
Air Care Climatronic with allergen filter
The Air Care Climatronic allergen filter can
reduce the amount of harmful substances,
including allergens, that get inside.
If the Air Care option is switched on, the air
conditioning’s air recirculation mode is
maximised until there is a risk of the windows
misting up due to humidity inside the vehicle
and the outside temperature. The air recir-
culation mode is automatically regulated and
incorporates an automatic setting to prevent
the vehicle occupants suffering from fatigue.
●
Open the air conditioning settings in the
infotainment system

page 147 .
●
Switch the Air Care function on or off using
active Air Care
.
WARNING
Stuffy or used air will increase fatigue and
reduce driver concentration possibly re-
sulting in a serious accident.
●
Never leave the fresh air fan turned off or
use the air recirculation for long periods of
time; the air in the vehicle interior will not
be refreshed.
●
If the cooling system is switched off and
air recirculation mode switched on, the
windows can mist over very quickly, consid-
erably limiting visibility.
CAUTION
Do not smoke when air recirculation is
switched on in vehicles with an air condi-
tioner. The smoke taken in could lie on the
cooling system vaporiser and on the activa-
ted charcoal cartridge of the dust and pol-
len filter, leading to a permanently un-
pleasant smell.
