Using the system
The heating system delivers air into the interior of the
vehicle and warms it as required.
Setting temperature
– Turn the control dial ⇒fig. 92 to the right in order to
increase the temperature.
– Turn the control dial to the left in order to increase the temperature. Controlling blower
– Turn the blower switch into one of the positions, 1 to 4, in
order to switch the blower on.
– Turn the blower switch into position 0 in order to switch the blower off.
– Pressing button causes the recirculating air system ⇒
to be switched on.
Control for air distribution
– You can adjust the direction of the inlet air flow ⇒page 98
using air distribution regulator .
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 prop-
erly.
All controls apart from the control dial can be set to any desired inter-
mediate position.
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, as “stale” air may result in fatigue in the driver and occu-
pants, 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 air distribution is positioned towards the windows, the total
amount of air is used to defrost the windows and thus no 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.
•Have the air conditioning system cleaned by a specialist workshop

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 recircul ated air mode on
– Press button , the button symbol
 lights up ⇒page 96,
fig. 92 .
Switching recirculat ed air mode off
– Press button again, the button symbol
 goes out.
The recirculated air mode is switched off automatically if the air distribu-
tion control is in position ⇒ page 96, fig. 92 . 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 occu-
pants, divert your attention and al so 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.

Redirecting air flow
– The horizontal as well as the vertical direction of the air flow is
set with the handle in the middle of the air outlet vents.
You can set the air supply to the individual vents with the air distribution
control ⇒page 96, fig. 92 . Air outlet vents 3 and 4 can also be opened
or closed individually.
Unwarmed or cooled air will flow out of the opened air outlet vents
according to the setting of the control dial ⇒page 96, fig. 92 and
according to atmospheric conditions.
Climatic (semi-automatic air
conditioning system)*
Description
Climatic is a combined cooling and heating system with
electronic control of the convenience temperature in the
vehicle interior. 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 air conditioning system operates when switch ⇒page 100,
fig. 94 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, 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 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
Climatic is operating which can only be eliminated through considerable
effort and expense (replacement of compressor).
Using the system
Setting temperature
– Turn the control dial ⇒fig. 94 to the right in order to
increase the temperature.
– Turn the control dial to the left in order to increase the temperature.
Controlling blower
– Turn the blower switch into one of the positions, 1 to 4, in order to switch the blower on.
– Turn the blower switch into position 0 in order to switch the blower off.
– Pressing button causes the recirculating air system ⇒page 102 to be switched on.
Control for air distribution
– You can adjust the direction of the inlet air flow ⇒page 103
using air distribution regulator .
Switching cooling on and off
– Press the button . The symbol
 in the switch comes on.
– When you again press the switch , the cooling system is switched off. The symbol
 in the button is no longer illumi-
nated.

conditions.
Using the air conditioni ng system economically
The compressor on the Climatic 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 problems
If the cooling system does not operate at outside temperatures higher
than +2 °C, there is a problem in the system. The reasons for this may be:
•The fuse of the Climatic is defective. Check the fuse, replace it if
necessary ⇒page 249.
•The cooling system has switched off automatically for a short time
because the coolant temperature of the engine is too hot ⇒page 14.
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.
