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).

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 ⇒page 112, fig. 139 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 au tomatically if the air distribution control
is in position  ⇒ page 112, fig. 139 . 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,
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 acci-
dent increases. Switch recirculated air mode off as soon as the windows
begin misting up.
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 the doors of a vehicle for which the inte-
rior 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 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 257.
•The cooling system has switched off automatically for a short time because the
coolant temperature of the engine is too hot ⇒page 18.
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 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
eliminates the need to alte r the settings manually. The automatic mode
¨ ⇒ page 117 ensures maximum wellbeing of th e 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 approx. +2°C,
• switched on.
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 ⇒page 118.
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 hi gh 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 all periods of the year:
•Set the desired temperature, we recommend 22 °C.
•Press the button ⇒page 116, fig. 140 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards.
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 108, fig. 136.
The ventilation functions only when the sliding/tilting roof is closed.

Automatic mode
The automatic mode is used in order to maintain a constant temper-
ature and to demist the windows in the interior of the car.
Switching automatic mode on
– Set a temperature between +18 °C and +26 °C.
– Move the air outlet vents 3 and 4 ⇒ page 108, fig. 136 so that the air
flow is directed slightly upwards.
– Press the button . In the right or left top corner a warning light lights up, depending on which unit was last selected.
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 Climatronic 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 noise
level, this is more comfortable, yet be aw are that the effectiveness of the air condi-
tioning system is reduced particularly if the vehicle is fully occupied.
By pressing again the button , yo u change into the “HIGH” mode. The automatic mode is switched off by pr
essing the button for the air distribution
or increasing or decreasing the blower speed. The temperature is nevertheless
regulated.

– When you again press the switch , the cooling system is switched off. The warning light in the button goes out. Only the function of the
ventilation remains active when no lower temperature than the
outside temperature can be reached.
Setting temperature
You can separate the interior temperature for the left and right side sepa-
rately.
– You can set the temperature for both sides after switching on the igni- tion with the control dial .
– If you wish to set the temperature for the right side, turn the control dial . The warning light in the bu tton lights up, this indicates
that differing temperatures for the left and right side can be set.
If the warning light in the button lights up, the temperature for both sides
cannot be set with the control dial . You can reinitiate this function by pressing
the button . The warning light in the button which indicates the possibility to
set differing temperatures for the left and right side, goes out.
You can set the interior temperature be tween +18°C and +26°C. The interior
temperature is regulated automatically within this range. If you chose a tempera-
ture lower than +18°C, a blue symbol lights up at the start of the numerical scale. If
you chose a temperature higher than +26°C, a red symbol lights up at the end of

cooling or heating capacity, respectively. The temperature is not controlled in this
case.
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.
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.
Switching recirculated air mode off
– Press again the button or the button - the warning light in
the button goes out.
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
attention and also cause the windows to mist up. The risk of having an acci-
dent increases. Switch recirculated air mode off as soon as the windows
begin misting up.
Note
If the windscreen mists up, press the button ⇒page 116, fig. 140 . After
the windscreen has been demisted, press the button .
Automatic air distribution control
When the automatic air distribution control is switched on, an air
quality sensor measures the concentration of pollutants in the drawn
in air.
If a considerable increase in concentr ation of pollutants is recognized by
the air quality sensor, the air distribution control will temporarily be
switched off. If the concentration of pollutants decreases to the normal
level, the air distribution control is au tomatically switched off so that fresh
air can be guided into the vehicle interior.
Switch on automatic air distribution control
– Press the button repeatedly * until the warning light on the right side of the button lights up.
Switch off automatic air distribution control temporarily
– If the air quality sensor does not switch on automatically when there
is a nauseating smell, you can switch it on yourself by pressing the
button *. The warning light lights up in the button on the left side.

Auxiliary heating (auxiliary heating and ventilation)*
Description and important information
The auxiliary heating (auxiliary heating 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) func tions 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) warms up the coolant during the combus-
tion 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.
11)
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).
