Air conditioning
Heating
Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
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
comfort for the vehicle occupants and prevents misting of the windows
when the ambient air humidity is high.
If the air conditioning system cannot be switched on this may be caused by
the following reasons:
● The engine is not running.
● The blower is switched off.
● The outside temperature is below +3°C.
● The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
● The air conditioner fuse is faulty.
● Another fault in the vehicle. Have the air conditioner checked by a speci-
alised workshop.

Air recirculation mode

Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.

Air conditioning
Air recirculation mode


 prevents strong odours in the outside
air from entering the vehicle interior, for example when passing through a
tunnel or in queuing traffic.
With low temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold 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'>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).

2C-Climatronic*
Controls
The controls allow separate adjustment of air conditioner settings for the left and right.
Fig. 110  On the dash panel: 2C Climatronic controls
The air conditioner controls the temperature when the engine is
running and the blower is switched on.
– Turn the temperature control knobs 
⇒ fig. 110
 to adjust the
temperature on the left hand side or the right hand side respec-
tively.
– The functions will be switched on when its buttons are pressed.
When these functions are activated, they are indicated on the
radio display. In addition, all these functions are lit with LEDs.
Press the button again to switch off the function.
The temperature can be adjusted separately for the left and right sides of
the vehicle interior.

 – defrost function for the windscreen. The air drawn in from
outside the vehicle is directed at the windscreen. The air recirculation
mode, if switched on, will be switched off as soon as the defrost func-
tion is switched on. At temperatures over 3°C, the air conditioning sys-
tem will be switched on automatically in order to dehumidify the air.
The button is lit in yellow and the symbol appears on the radio or navi-
gator display.

WARNING
For road safety all windows must be clear of ice, snow, and condensation.
This is essential to ensure good visibility. Please familiarise yourself with
the correct operation of the heating and ventilation system, including the
anti-fog/defrost functions for the windscreens.
