142 Air conditioning
When the button is off (LED off), the air conditioning system is off.
A/C
When the button is off, the air conditioning system is switched off to
A/C
save fuel. The temperature continues to self-regulate. The set temperature
can then only be reached if it is higher than the outside temperature.
Driver and passenger temperature control
The button controls the synchronisation of the 2 Climatronic climate
SYNC
zones.
When the button is off (LED off), the climate zone of the Climatronic
SYNC
system is personalised. For example: driver side temperature +22 °C
(+72 °F) and passenger side temperature +24 °C (+75 °F).
When the button is on (LED lit), the climate zone of the Climatronic
SYNC
system is synchronised. For example: driver side temperature +22 °C
(+72 °F) and passenger side temperature +22 °C (+72 °F).
If the button is on and the passenger side temperature is changed,
SYNC
the function is automatically deactivated.
Air recirculation mode
– Press the button

mode on or off. It is switched on if the following symbol appears
in the display .
Air recirculation mode prevents strong odours or contaminated air from the
outside from entering the vehicle, for example when passing through a tun-
nel or in a traffic jam.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside.

With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle
rather than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be connec-
ted.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).

General notes

Pollution filter
The pollution filter (a combined particulate filter and active carbon filter)
serves as a barrier against impurities in the outside air, including dust and
pollen.
For the air conditioner to work with maximum efficiency, the pollution filter
must be replaced at the intervals specified in the Service Plan.
If the filter loses efficiency prematurely due to use in areas reaching very
high pollution levels, the pollen filter must be changed more frequently
than stated in the Service Schedule.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves
