Heating and air conditioning system
Introduction
Description and information The heating effect is dependent upon the coolant temperature, thus full heat out-
put only occurs when the engine has reached its operating temperature.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The well-being 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.
It is possible to briefly activate recirculated air mode in order to enhance the cool-
ing effect - air-conditioning system ⇒
 page 89, Climatronic ⇒ page 92.
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 win-
dows 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 at-
tention 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
● The used air streams out through the air removal openings in the luggage
compartment.
● 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 in-
terior of the vehicle forms deposits in the evaporator of the air conditioning sys- tem. This produces a permanent odour when the air conditioning system is oper-
ating which can only be eliminated through considerable effort and expense (re-
placement of compressor).
● Please refer to the information regarding the recirculated air mode for heating
⇒

  page 89 and/or for air-conditioning system ⇒ page 89 or Climatronic
⇒  page 92.
● To ensure that the heating and air conditioning systems work properly, do not
block up the air outlet vents with any objects. 
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 al-
low 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 220.
● The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot ⇒ page 11.
If you are not able to rectify the operational problem yourself, or if the cooling ca-
pacity decreases, switch the cooling system off. Contact a specialist garage. 86

The cooling only operates if button
AC ⇒ 
fig. 91 1 is pressed, and the following
conditions are met:
● engine running,
● outside temperature above approx. +2 °C and
● blower switch switched on (positions 1 to 4).
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 and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons. Note

Climatronic (automatic air conditioning) Description The Climatronic system is an automatic heating, fresh air and cool-
ing 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 out-flowing air, the
blower stages and the air distribution. The system also takes into account sun-
light which eliminates the need to alter the settings manually. The automatic
mode
⇒

 page 93 ensures maximum well-being 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 approx. +2 °C,
● AC switched on.
The AC compressor is switched off at a high coolant temperature in order to en-
sure cooling of the engine at high loads.
Recommended setting for all periods of the year:
● Set the desired temperature, we recommend 22 °C.
● Press the button AUTO
⇒  fig. 92 .
● Move the air outlet vents 3 and 4 ⇒
 fig. 88 so that the air flow is directed
slightly upwards. Note
● We recommend that you have Climatronic cleaned by a specialist garage once
every year.
● On vehicles equipped with a factory-fitted radio or radio navigation system,
the information of the Climatronic is also shown on the display. This function can
be switched off, see operating instructions of the radio or the radio navigation
system. 

Recirculated air mode In recirculated air mode air is sucked out of the interior of the vehi-
cle and then fed back into the interior. When the automatic air dis-
tribution control is switched on, an air quality sensor measures the
concentration of pollutants in the drawn in air.
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 traf-
fic jam. If a considerable increase in concentration of pollutants is recognized by
the air quality sensor, when the automatic air distribution control is switched on,
the air distribution control will temporarily be switched off. If the concentration of
pollutants decreases to the normal level, the air distribution control is automati-
cally switched off so that fresh air can be guided into the vehicle interior.
Switching recirculated air mode on
– Press the button repeatedly  until the warning light on the left side of the
button lights up.
Switch on automatic air distribution control
– Press the button repeatedly  until the warning light on the right side of the
button lights up.
