Heating
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. 105 to the right in order to increase the
temperature.
– Turn the control dial to the left in order to increase the tempera-
ture.
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 air flow using air distribution regu-
lator ⇒page 85.
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.
All controls apart from the control dial can be set to any desired intermediate 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 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 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.

Heating and air conditioning system86
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 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 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).
Using the system
Setting temperature
– Turn the control dial ⇒fig. 107 to the right in order to increase the
temperature.
– Turn the control dial to the left in order to increase the tempera-
ture.

Heating and air conditioning system90
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 ⇒.
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 high 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 temperature to 22 °C.
•Press the button ⇒fig. 109.
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly upwards ⇒page 93, fig. 110.
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒fig. 109. The information in the desired temperature measuring unit appears in the display.
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.
