Air conditioning
Cooling system
For reasons of safety, air recirculation is not possible when the control for air
distribution is set to the windscreen setting .
When the cooling 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 outside
air humidity is high.
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.
If the cooling system cannot be switched on this may be due to the following
reasons:
•
•
•
•
the engine is not running.
The blower is switched off.
The outside temperature is lower than approx. +5°C.
the cooling system compressor has been temporarily switched off
Note
When reverse gear is engaged the air recirculation connects automatically to
prevent the entrance of exhaust fumes in the vehicle on travelling backwards.
because the engine coolant temperature is too high.
The control light on the button
does not light up.
•
•
The air conditioner fuse is faulty.
Another fault in the vehicle. Have the air conditioner checked by a quali-
fied workshop.
Economic use of the air conditioning
When the air conditioning is switched on, the compressor consumes engine
power and has an effect on fuel consumption. Observe the following points
in order to have the equipment operating for a short a time as possible.
Air recirculation
Air recirculation mode prevents fumes or unpleasant smells
from entering the vehicle.
•
If the vehicle interior has overheated due to excessive solar radiation, it is
best to open the windows or doors to allow the hot air to escape.
When travelling the air conditioning should not be switched on if the
windows or sun roof are open.*
When air recirculation mode is switched on (button ⇒ page 117, fig. 89
with warning lamp) strong odours in the outside air do not enter the vehicle
•
interior, for example when passing through a tunnel or in queuing traffic.
When the outside temperature is low, using air recirculation mode provides
more effective heating by heating air from the vehicle interior instead of cold
air from outside.
When the outside temperature is high, using air recirculation mode provides
more effective cooling by cooling air from the vehicle interior instead of warm
air from outside.
