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 interior of the vehicle forms deposits in the evapor
ator of the air conditioning system. This
produces a permanent odour when the air co
nditioning system is operating which can
only be eliminated through considerable
effort and expense (replacement of
compressor).Using the systemFig. 109 Climatic: Control elementsSetting temperature– Turn the control dial

If the cooling system has not been switched on for a lengthy period, odours may
be produced at the evaporator because of
deposits. Switch the cooling system on at
least once a month for approximately 5 minu
tes at the highest blower stage - also
during the cold season of the year - in order to remove such odours. Also open a window for a short time.

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 standi
ng in a traffic jam.
Switching recirculated air mode on– Press the button
⇒page 99, fig. 109
the warning light lights up in the
button.
Switching recirculated air mode off– Press again the button - the warning light in the button goes out. The recirculated air mode is switched off automatically if the air distribution control is in position
⇒page 99, fig. 109
. You can also switch recirculated air mode on
again from this setting by re
peatedly pressing button .
WARNING
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 atten- tion 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.Using the air conditioning system economicallyThe compressor on the air conditioning syst
em 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 interior
has been strongly heated through the effect
of direct 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 switching to fresh air mode.
For the sake of the environment
When you economize on fuel, you
also reduce pollutant emissions.
Operational problemsIf 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 233.
•
The cooling system has switched off auto
matically for a short time because the
coolant temperature of the engine is too hot
⇒page 17.
If you are not able to rectify the operational
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 combination of an automatic heating, fresh air and cooling system which provides optimal comfort for the occu-pants of the car.The Climatronic maintains fully automatically a convenience temperature. This is achieved by automatically varying the temperature of the outflowing air, the blower stages and the air distribution. The system also takes into account sunlight which elim- inates the need to alter the settings manually. The
automatic mode

If the warning light in the top right corner of the button lights up, the Climatronic operates in “HIGH” mode. The “HIGH” mode is the standard setting of the Climatronic. When pressing again the button , the Cl
imatronic changes into the “LOW” mode
and the warning light in the top left corner lights up. The Climatronic uses only in this mode the lower blower speed. However taking
into account the no
ise level, this is
more comfortable, yet be aware that the effectiveness of the air conditioning system is reduced particularly if th
e vehicle is fully occupied.
By pressing again the button , yo
u change into the “HIGH” mode.
The automatic mode is switched off by pres
sing the button for the air distribution or
increasing or decreasing the blower speed. The temperature is nevertheless regulated.

Auxiliary heating (auxiliary heating and ventilation)*Description and important information The auxiliary heating (auxiliary he
ating and ventilation) heats or
supplies the interior of the vehicl
e with fresh air independent of the
engine.Auxiliary heating (auxiliary heating) The auxiliary heating (auxiliary heating) functions in connection with the Climatic or Climatronic. It can be used when stationary, when engi
ne is switched off for preheating of the
vehicle as well as while driving (only during the heating phase of the engine). The auxiliary heating (auxiliary heating) wa
rms up the coolant during the combustion
of fuel from the vehicle tank. The coolant warms up the air, which (if the blower speed is not set to zero) flows into the occupant compartment. Auxiliary ventilation The auxiliary ventilation enables fresh air to flow into the vehicle interior by switching off the engine, whereby the interior temperature is effectively decreased (e.g. with the vehicle parked in the sun).
