Heating and air conditioning system
120
The heating effect is dependent upon the coolant temperature, thus full
heat output only occurs when the engine has reached its operating
temperature.
The blower should aways be on to prevent the windows from misting up.
WARNING
You should not leave recirculated air mode on over a longer period
of time. “Stale air” may result in fatigue in the driver and passen-
gers, reduce attention levels 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
•The whole heat output will be needed to unfrost the windscreen and
side windows. No warm air will be fed to the footwell. This can lead to
restriction of the heating comfort.
•The used air streams out through the air removal openings in the
luggage compartment.
Set heating
Recommended settings of heating controls for:
Defrosting the windscreen and side windows
•Turn control dial ⇒ page 119, fig. 116 to the right up to the stop
•Blower switch in position 3
•Turn the air distribution control into the position 
•Open air outlet vents 3 ⇒ page 122, fig. 117 and point towards the side
window.
•Close the air outlet vents 4
Keeping windscreen and side windows demisted
We recommend that you use the following setting in cases where the
windows are misted up more than usual (e.g. when it is raining):
•Control dial where necessary to the heating range
•Blower switch in position 2 or 3
•Control dial to  or  as required or to any desired position
between these symbols
•Open air outlet vents 3 and point towards the side window
•Close the air outlet vents 4
Warming up the inside of the ve hicle as rapidly as possible
•Turn control dial to the right up to the stop
•Blower switch in position 3
•Turn the air distribution control into the position 
•Open the air outlet vents 3 and 4
•We recommend briefly pressing button air recirculation mode. The
windows can steam up in this position however.
Heating the vehicle to a comfortable temperature
We recommend the following setting once the windows are no longer
misted up and the desired teperature has been reached:
•Control dial at the desired heat output
•Blower switch in position 2 or 3
•Turn the air distribution control into the position 
•Open the air outlet vents 3
•Close the air outlet vents 4
•Set the air distribution regulator as required between positions 
and , if the windscreen gets misted up again.

the following settings.
Recirculated air mode must not be switched on.
•Turn the control dial ⇒p a g e 11 9 , f i g . 11 6 to the left up to the stop

•Open air outlet vents 3 and 4 ⇒ page 122, fig. 117
The control dial can be set to other positions as required.
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.
Switching recirculated air mode on
– Press the button - the warning light lights up in the button ⇒page 119, fig. 116 .
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 distribu-
tion control is in position  ⇒ page 119, fig. 116 . You can also switch recirculated air mode on again from this setting by repeatedly pressing
button .
WARNING
You should not leave recirculated air mode on over a longer period
of time. “Stale air” may result in
fatigue in the driver and passen-
gers, reduce attention levels 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.AA

– Turn the vertical thumbwheel into the end position.
Redirecting air flow
– Swivel upward or downward the gr
ille of the vents in order to
change the direction of the air flow using the vertically
arranged thumbwheel.
– Turn the horizontal thumbwheel on the vent to the right or left in order to change the air flow to the appropriate side.
You can set the air supply to the individual air outlet vents using the control
dial ⇒p a g e 11 9 , f i g . 11 6 . Air outlet vents 3, 4 ⇒ fig. 117 and 6 ⇒ fig. 118
can also be opened or closed individually.
The air outlet vents 6 are only fitted on vehicles with higher centre
console.
Unwarmed or cooled air will flow out of the opened air outlet vents
according to the setting of the control dial ⇒page 119, fig. 116 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 cooling 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 operating properly.
The cooling only operates if button ⇒page 124, fig. 119 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, 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 the 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 ⇒.
Air at a temperature of about 5°C may flow out of the vents under certain
circumstances 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 conditioning 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 misting. Please familiarize
yourself about how to correctly operate the 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. “Stale air” may result in fatigue in the driver and
passengers, reduce attention levels and also cause the windows to
mist up. The risk of having an accident increases. Switch recircu-
lated air mode off as soon as the windows begin misting up.
Note
•We recommend that you do not smoke in the vehicle when the recir-
culating air mode is operating since the smoke which is drawn at the evap-
orator from the interior 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
considerable effort and expense (replacement of compressor).

•The used air streams out through the air removal openings in the
luggage compartment.
•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 minutes
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.
•Please refer to the information regarding recirculated air mode
