With the regulator the heating level is determined. The required tempera-
ture inside the vehicle cannot be lower than the ambient temperature. Maximum heat output, which is needed to defrost the windows quickly, is
only available when the engine has reached its operating temperature.

With low outside temperatures, the air recirculation increases the effective-
ness of the heating system by heating the air inside the vehicle rather than
the air from outside.
Air distribution
Control for setting the flow of air in the required direction.
< – Air distribution towards the windscreen. If the windscreen air output is
on and the air recirculation mode is pressed, this remains active. When the
recirculation mode is on, if the air distribution towards the windscreen mode
is selected, the recirculation mode is deactivated. For safety reasons, the air
recirculation mode should not be connected. – Air distribution to the upper body – Air distribution to footwell – Air distribution to the windscreen and the footwell
Blower
The air flow can be set at four speeds with the knob . The air flow 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 heating and ventilation system, including
the anti-fog/defrost functions for the windscreens.•In air recirculation mode, no cold air from the outside enters the vehicle
interior. The windows can quickly fog over if the heating is switched off.
Therefore, never leave the air recirculation mode switched on for a long
time (risk of accident).Note
Please observe the general notes ⇒page 158.

– Use the air distribution control to guide the flow of air in the required direction: (to the windscreen), (to the upper
body), (to the footwell) and (to the windscreen and to the
footwell).Heating
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 system cannot be switched on this may be caused by
the following reasons:
•The engine is not running.•The blower is switched off.•The outside temperature is below +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 special-
ised workshop.
Air recirculation mode
Air recirculation mode prevents fumes or unpleasant smells from coming from the outside.

Air recirculation mode
⇒page 152, 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 temperatures outside, the air recirculation increases the effective-
ness of the heating system by warming the air inside the vehicle rather than
the cold air from outside.
With high outside temperatures, the air recirculation increases the effective-
ness of the air conditioning system by cooling the air inside the vehicle rather
than the ambient air.
If the windscreen air output is on and the air recirculation mode is pressed,
this remains active. When the recirculation mode is on, if the air distribution
towards the windscreen mode is selected, the recirculation mode is deacti-
vated. For safety reasons, the air recirculation mode should not be
connected.
WARNING
In air recirculation mode, no cold air from the outside enters the vehicle
interior. If the air conditioning system is switched off, the windows can
quickly mist over. Therefore, never leave the air recirculation mode
switched on for a long time (risk of accident).
