Deluxe automatic climate control
Applies to veh icles : wit h deluxe automat ic climat e cont rol
Description
The climate control system can be used to set a comfort-
able temperature inside the vehicle.
The climate control system is a combination of a heating and ventila-
tion system as well a cooling system responsible for dehumidifying
and cooling the air inside the vehicle.
The automatic climate control system automatically maintains a
temperature once it has been set. The temperature of the air from
the vents, fan speed (air volume) and air distribution are a lso auto-
matically adjusted. The system also takes into account strong
sunlight so that manual adjustment is not necessary . So in almost all
cases,
automatic mode offers the best conditions for the comfort of
the occupants at all times of the year =>
page 89.
Please note the following :
The cooling mode lowers the humid ity level inside the vehicle. This
prevents fogging up of the windows.
In the case of high outside humidity and temperatures,
condensation
can drip from the air conditioning system evaporator and form a pool
unde r the vehicle . This is normal and not an indication of leaks!
At low outside temperatures, the fan automatically switches to a
higher speed when the coo lant reaches a sufficient temperature
except in the defroster position .
When starting with fu ll thrott le, the compressor of the automatic
climate contro l system is temporarily switched off to achieve f ull
eng ine power .
To ensure engine cooling when the engine is under an extreme load,
the compressor is switched off at high coolant temperatures.

Pollutant filter
The pollutant filter (particle filter) ensures that impurities in the
outs ide air (e.g. dust, pollen) and odors are significantly reduced or
stopped . The air is also filtered in recirculation mode.
The pollutant filter element must be changed at the intervals speci-
fied in the service plan so that the performance of the automatic
climate contro l system is not impaired.
If the effectiveness of the filter dec reases prematurely due to opera-
tion of t he vehicle in areas with significant pollution, the filter
element must be changed between the spec ified service dates.
Key recognition
The cur rent automatic clima te control sett ings are automatically
stored and assigned to the master key.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components wh ich require large amounts of
energy are temporarily cut back or switched off =>
page 235. Heating
systems in particular require a great deal of energy. If you notice , for
example, that the rear window heater is not heating, then it has been
temporarily reduced or switched off by
energy management . These
systems are available again as soon as the energy balance has been
restored.
& WARNING
Traffic safety requires all window s to be clear of ice, snow, and
condensation. Only then can good visibility be ensured . Famil-
iarize yourself with the correct operation of the automatic climate
control system as well as the proper procedure for defog-
ging/defrosting the windows. _,.
