Heating and air conditioning system
Air conditioning system
Description
The air conditioning system 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 air conditioning system
It is important for your safety and for your driving comfort that the air conditioning
system is operating properly.
The air conditioning system operates when switch ⇒page 90, fig. 106 is
pressed and the following conditions are met:
•engine running,
•outside temperature above +5 °C,
•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 outs ide 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 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 ventilation 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!
Aeration of the vehicle when ignition is switched off*
On models fitted with power sliding/tilting roof with sollar cells, the fresh air blower
is automatically switched over to “solar mode ” if the sun ray's are sufficient after
switching off the ignition. The solar cells on the sliding/tilting roof deliver power for
the fresh air blower. This supplies the interior of the car with fresh air.
For an optimum ventilation, the air outlet vents 3 and 4 must be opened
⇒ page 92.
The ventilation functions only when the sliding/tilting roof is closed.
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 ev aporator of the air conditioning system.
This produces a permanent odour when th e 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 system uses power from the engine when
in cooling mode which will effect the fuel consumption.
It recommended to open the windows or th e doors of a vehicle for which the inte-
rior has been strongly heated through the ef fect 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 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 of the air conditioning system is defective ⇒page 220. Check the fuse,
replace it if necessary.
•The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot.
If you are not able to rectify the operat ional problem yourself, or if the cooling
capacity decreases, switch the cooling sy stem 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 occupants of the car.
The Climatronic maintains a constant temper ature 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. It is not necessary to
manually alter the settings. The automatic mode ⇒ page 95 ensures maximum
wellbeing of the occupants at all times of the year.
Description of Climatronic system
The Climatronic can only operate if the following conditions are met:
•engine running,
•outside temperature above +5 °C,
•the button is not pressed.
If the Climatronic 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 temperatur es and a high air humidity. The system
prevents the windows misting up during the cold season of the year.
It is possible to briefly activate recirc ulated air mode in order to enhance the
cooling effect ⇒.
The heating effect is dependent upon th e coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
Puddle of water below car
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!
Switching over between degrees Celsius and degrees Fahrenheit
First of all press and hold the button ⇒page 94, fig. 109 and then press the
button . The temperature measur ing unit appears in the display.ECON

An acoustic signal for depressed buttons
Simultaneous pressing of buttons and can be used to de-activate or
activate this function.
A higher tone is heard when switching on this function, when increasing the blower
speed or when increasing the temperature.
A lower tone is heard when switching off this function, when decreasing the blower
speed or when decreasing the temperature.
Aeration of the vehicle when ignition is switched off*
On models fitted with power sliding/tilting roof with sollar cells, the fresh air blower
is automatically switched over to “solar mode ” if the sun ray's are sufficient after
switching off the ignition. The solar cells on the sliding/tilting roof deliver power for
the fresh air blower. This supplies the interior of the car with fresh air.
For an optimum ventilation, the air outlet vents 3 and 4 must be opened
⇒ page 97.
The ventilation functions only when the sliding/tilting roof is closed.
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
•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 air conditioning
system on at least once a month for appr oximately 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.
•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 th e air conditioning system is operating
which can only be eliminated through co nsiderable effort and expense (replace-
