Recirculated air mode
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.
Recirculated air mode prevents polluted air outside the vehicle from
getting into the vehicle, for example when driving through a tunnel or
when standing in a traffic jam.

Unwarmed or cooled air will flow out of the opened air outlet vents according to
the setting of the control dial ⇒page 100, fig. 119 and according to outer
atmospheric conditions.
Note
The air outlet vents 2 ensure in the ventilation mode for a comfortable (no-draught)
ventilation of the interior of the vehicle, also if the air outlet vents 4 are closed.
Climatic* (semi-automatic air conditioning system)
Description
The Climatic is a combined coolin g and heating system. It makes it
possible to optimally control the air temperature at any season of the
year.
Description of the Climatic
It is important for your safety and for your driving comfort that the Climatic is oper-
ating properly.
The cooling only operates if button ⇒page 104, fig. 122 is pressed, and the
following conditions are met:
•engine running,
•outside temperature above +2 °C and
•blower switch switched on (positions 1 to 4).
If the cooling system is switched on, th e temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this
particularly at high outside temperatur es and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
The heating effect is dependent upon th e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirc ulated air mode in order to enhance the
cooling effect ⇒.
Air at a temperature of about 5°C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of
the air flow out of the vents (in particular at the leg area) and large differences in
temperature, for example when getting out of the vehicle, can result in chills in
sensitive persons.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the heating and cooling systems operate properly.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle below the vehicle. This is quite normal
and not an indication of a leak!
WARNING
•For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mistin g. Please familiarize yourself about
how to correctly operate th e heating and ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.
•You should not leave recirculated air mode on over a longer period of
time, as “stale” air may result in fatigue in the driver and occupants, divert
your attention and also cause the windows to mist up. The risk of having an
accident increases. Switch recirculated air mode off as soon as the windows
begin misting up.

Note
•We recommend that you do not smoke in the vehicle when the recirculating air
mode is operating since the smoke which is drawn at the evaporator from the inte-
rior of the vehicle forms deposits in the evaporator of the air conditioning system.
This produces a permanent odour when the air conditioning system is operating
which can only be eliminated through co nsiderable effort and expense (replace-
ment of compressor).

Using the air conditioning system economically
The compressor on the air conditioning sy stem uses power from the engine when
in cooling mode which will effect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the inte-
rior has been strongly heated through the effect of di rect sunlight in order to allow
the heated air to escape.
The cooling system should not be switched on while travelling when the window is
open.
The desired interior temperature can also be achieved without switching in the
cooling system just by sw itching to fresh air mode.

For the sake of the environment
When you economize on fuel, you also reduce pollutant emissions.
Operational problems
If the cooling system does not operate at outside temperatures higher than +5 °C,
there is a problem in the system. The reasons for this may be:
•The fuse on the air conditioning system has blown. Check the fuse, replace it if
necessary ⇒page 243.
•The cooling system has switched off auto matically for a short time because the
coolant temperature of the engine is too hot ⇒ page 11.
If you are not able to rectify the operat ional problem yourself, or if the cooling
capacity decreases, switch the cooling system off. Contact a specialist garage.
Climatronic* (automatic air conditioning)
Description
The Climatronic system is a combin ation of an automatic heating,
fresh air and cooling system which provides optimal comfort for the
occupants of the car.
The Climatronic maintains a constant temperature fully automatically, once it has
been set. This is achieved by automa tically varying the temperature of the
outflowing air, the blower stages and the air distribution. The system also takes into
account bright sunlight which eliminates the need to alter the settings manually.
The automatic mode ⇒ page 110 ensures maximum wellbeing of the occupants
at all times of the year.
Description of Climatronic system
The cooling operates only if the following conditions are met:
•engine running,
•outside temperature above +2 °C,
•the button is not pressed.
If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this
particularly at high outside temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
The heating effect is dependent upon th e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
It is possible to briefly activate recirculated air mode in order to enhance the
cooling effect ⇒.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the heating and cooling systems operate properly.
The AC compressor is switched off at a high coolant temperature in order to provide
cooling at a high load of the engine.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle below the vehicle. This is quite normal
and not an indication of a leak!
Recommended setting for al l periods of the year:
•Set the temperature to 22 °C (72 °F).
•Press the button ⇒page 109, fig. 125 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards
⇒ page 112, fig. 126 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 109, fig. 125 . The informa-
tion in the desired temperature measuring unit appears in the display.
WARNING
•For your own safety and that of other road users, ensure that all the
windows are free of ice, snow and mist ing. Please familiarize yourself about
how to correctly operate the heating an d ventilation systems, how to demist
and defrost the windows, as well as with the cooling mode.
