LED is lit. This way, incoming air is cooled  
and dehumidified sufficiently. When AC OFF  
is selected and the OFF LED lights, the air  
conditioning system is disconnected; other  
functions are still controlled automatically.  
The air conditioning system operates down to  
approximately 0 °C.  
Certain cars are equipped with a "Multifilter"  
and air quality sensor. The Multifilter  
separates gases and particles, thus reducing  
the volume of odours and pollutants entering  
the car. The air quality sensor detects  
increased levels of contaminants in the  
outside air. When the air quality sensor  
detects contaminated outside air, the air  
intake is closed and the air in the

Operation  
3. Recirculation  
4. AUTO  
Recirculation can be used to shut out bad air,  
exhaust, etc. from the passenger  
compartment. The air in the passenger  
compartment is then recirculated, i.e. no air  
from outside the car is taken into the car  
when this function is activated.  
The AUTO function automatically regulates  
climate control so that the desired temper-  
ature is attained. The automatic function  
controls heating, air conditioning, fan speed,  
recirculation, and air distribution. If you select  
one or more functions manually, the other  
functions continue operating automatically.  
All manual settings are switched off when  
AUTO is switched on.  
Press  
to activate the air  
quality sensor (normal setting).  
Or:  
Select one of the following three functions by  
pressing  
repeatedly.  
If you allow the air in the car to recirculate,  
there is a risk of icing and misting, especially  
in winter.  
AUT LED lit: The air quality sensor is now  
activated.  
No LED lit: Recirculation is not activated  
unless needed to cool in a warm climate.  
MAN LED lit: Recirculation is now  
activated.  
5. Air distribution  
The timer function (cars with Multifilter and air  
quality sensor have no timer function)  
minimises the risk for ice, misting and bad air.  
When the top button is depressed, air is  
directed to the windows.  
When the centre button is depressed, air  
is directed to the head and body.  
When the lower button is depressed, air  
is directed to the legs and feet.  
Keep in mind the following:  
Activate the function as follows:  
Make it a rule to have the air quality  
sensor activated at all times.  
Recirculation is limited in cold weather to  
avoid misting.  
If misting occurs, you should deactivate  
the air quality sensor.  
If misting occurs, you can use the  
defroster functions for the windscreen,  
side windows and rear window, see  
page 67.
