Heating and air conditioning system
128
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 +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 288.
•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.
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 temperature fully automatically,
once it has been set. This is achieved by automatically varying the
temperature of the outflowing air, the blower stages and the air distribu-
tion. The system also takes into account bright sunlight which eliminates
the need to alter the settings manually. The automatic mode ⇒ page 130
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.
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 ⇒.ECON

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 conditioning 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 (72 °F).
•Press the button ⇒page 130, fig. 122 .
•Move the air outlet vents 3 and 4 so that the air flow is directed slightly
upwards ⇒page 133, fig. 123 .
Switching over between degrees Celsius and degrees Fahrenheit
Press and hold the buttons and ⇒page 130, fig. 122 . 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.
•You should not leave recirculated air mode on over a longer
period of time. “Stale air” may result in fatigue in the driver and
passengers, reduce attention levels 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
•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 cooling system on at least once a month for approximately 5 minutes
at the highest blower stage - also during the cold season of the year - in
order to remove such odours. Also open a window for a short time.
•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
air conditioning system is operating which can only be eliminated through
considerable effort and expense (replacement of compressor).
•The used air streams out through the air removal openings in the
luggage compartment.
•The Information of the Climatronic is displayed on the display of the
radio*. You can also switch off this function - see operating instructions for
radio

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 the button - the warning light lights up in the button.
Switching recirculat ed 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. “Stale air” may result in fatigue in the driver and passen-
gers, reduce attention levels 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 windscreen mists up, press the button ⇒page 130, fig. 122 .
After the windscreen has been demisted, press the button .
Setting temperature
You can separate the interior temperature for the left and right
side separately.
– You can set the temperature for both sides after switching on the ignition with the control dial .
– If you wish to set the temperature for the right side, turn the control dial .
If the temperature for the right side was set via the control dial , it can
no longer be set via the control dial - temperature for both sides. This
is only possible if you press the button for about 2 seconds.
You can set the interior temperature between +16 °C (60 °F) and +29.5
°C (85 °F). The interior temperature is regulated automatically within this
range. If you select the temperature below +16 °C (60 °F), “LO” appears
in the display. If you select the temperature higher than +29.5 °C (85 °F),
“HI” appears in the display. In both limit positions the Climatronic operates
at maximum 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 partic-
ular at the leg area) and large differences in temperature, for example
when getting out of the vehicle, can result in chills in sensitive persons.
Controlling blower
There are a total of seven blower stages available.
The Climatronic system controls the blower stages automatically
in line with the interior temperature. You can also, however,
adapt the blower stages manually to suit your particular needs.

Auxiliary heating (auxiliary heating and
ventilation)*
Description
The auxiliary heating (auxiliary heating and ventilation)
heats or supplies the interior of the vehicle with fresh air
independent of the engine.
Auxiliary heating (auxiliary heating )
The auxiliary heating (auxiliary heating) functions in connection with the
heater or with the Climatic or Climatronic.
It can be used when stationary, when engine is switched off for preheating
of the vehicle as well as while driving (e.g. during the heating phase of the
engine).
The auxiliary heating (auxiliary heating) warms up the coolant during the
combustion 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.
6)
Auxiliary ventilation
The auxiliary ventilation enables fresh air to flow into the vehicle interior
by switching on the blower, if the blower speed is not set to zero, whereby
the interior temperature is effectively decreased (e.g. with a vehicle
parked in the sun).
6)However the coolant does not warm up the engine.
