Heating and air conditioning system80
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.
Air outlet vents
Fig. 94 Air outlet vents
Open air outlet vents
– Turn the rotary knob into the upper position.
Close air outlet vents
– Turn the rotary knob into the lower position.
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 78, fig. 93. Air outlet vents 3 and 4 can also be opened or closed individu- ally.
Unwarmed or cooled air will flow out of the opened air outlet vents according to the setting of the control dial ⇒page 78, fig. 93 and according to atmospheric conditions.
Climatic (semi-automatic air conditioning system)*
Description
Climatic is a combined cooling an d heating system with electronic
control of the convenience temperat ure in the vehicle interior. It
makes it possible to optimally co ntrol 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 oper- ating properly.
The air conditioning system operates when switch ⇒page 81, fig. 95 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 th e 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 ⇒.

Using the systemSafetyDriving TipsGeneral MaintenanceBreakdown assistancePraktikTechnical Data
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 cooling 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!
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 Climatic is operating which can only be eliminated through considerable effort and expense (replacement of compressor).

The controls and can be set to any desired intermediate position.
The blower should aways be on to prevent the windows from 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.
•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 th e year - in order to remove such odours. Also open a window for a short time.
•Please refer to the information regarding recirculated air mode ⇒page 83.
•Have the air conditioning system cleaned by a specialist workshop.

Unwarmed or cooled air will flow out of the air outlet vents according to the setting of control dial ⇒page 81, fig. 95 and the atmospheric conditions.
Using the air conditioning 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 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 +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 207.
•The cooling system has switched off automatically for a short time because the coolant temperature of the engine is too hot ⇒page 10.
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.
If there is a fault at the Climatronic, all symbols on the display flash after switching on the ignition for 15 seconds. 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. The system also takes into account sunlight which eliminates the ne ed to alter the settings manually. The automatic mode ⇒page 86 ensures maximum wellbeing of the 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 +2 °C,
•the button is not pressed.
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.
