Te c h n i c a l D a t a
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the air from outside.
Air distribution
Control for setting the flow of air in the required direction.
 – Air distribution towards the windsc
reen. Air recirculation is, for safety
reasons, not possible in this position. – Air distribution to the upper body. – Air distribution to foot well – Air distribution to the windscreen and the foot well.
Blower
The airflow can be set at four speeds with the control . The airflow should
always be set at the lowest speed when driving slowly.
WARNING
•
For road safety all windows must be clear of ice, snow, and condensa-
tion. This is essential to ensure good visibility. Please familiarise yourself
with the correct operation of the heat ing and ventilation system, including
the anti-fog/defrost functions for the windows.
•
In air recirculation mode, no ambient air enters the vehicle interior. The
windows can quickly fog over if the heating is switched off. Therefore, you
should never leave the air recirculat ion mode switched on for longer
periods, as this increases the risk of an accident.Note
Please observe the general notes ⇒page 149.

Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.
Air conditioner
When the air conditioning system is switched on, not only the temperature,
but also the air humidity in the vehicle interior is reduced. This improves comfort for the vehicle occupants and prevents misting of the windows when
the ambient air humidity is high.
If
the air conditioning syst em cannot be switched on, this may be caused by
the following reasons:
•
The engine may not be running.
•
The blower is switched off.
•
The ambient air temperature is lower than +3°C.
•
The air conditioning system compressor has been temporarily switched
off because the engine coolant temperature is too high.
•
The air conditioner fuse is faulty.
•
Another fault in the vehicle. Have the air conditioner checked by a quali-
fied workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells from entering the vehicle.

Air recirculation mode
⇒page 144, fig. 109 prevents strong odours in
the outside air from entering the vehicle interior, for example when passing
through a tunnel or in queuing traffic.
With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by warming the air inside the passenger compart-
ment rather than the air from outside.
With high ambient temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the passenger
compartment rather than the air from outside. For reasons of safety, air recirculation is
not possible when the control for air
distribution is set to the windscreen setting .
WARNING
In air recirculation mode, no ambient air enters the vehicle interior. If the
air conditioning system is switched off, the windows can quickly mist over.
Therefore, you should never leave the air recirculation mode switched on
for longer periods, as this increases the risk of an accident.
