Deluxe automatic climate control
Applies to vehicles: with deluxe automat ic climate cont ro l
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 respons ible for dehumid ifying
and cooling the air inside the vehicle.
Th e 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 90.
Please note the following :
The cooling mode lowers the humidity 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
under the veh icle. This is normal and not an indication of leaks!
At low outs ide temperatures, the fan automatically switches to a
higher speed when the coolant reaches a sufficient temperature
except in the defroster position.
When starting with full throttle, the compressor of the automatic
climate control system is temporarily switched off to achieve full
engine power.
T o ensure engine cooling when the engine is under an extreme load,
the compressor is switched off at h igh coolant temperatures.
Pollutant filter
The pollutant filter (particle filter) ensures that impurities in the
outs ide a ir (e.g. dust, pollen) and odors are significantly reduced or
stopped. The air is also filtered in recirculation mode.
Th e pollutant filter e lement must be changed at the intervals speci­
fied in the service plan so that the performance of the automatic
climate control system is not impaired.
If the effect iveness of the filter decreases premat urely due to opera­
tion of the vehicle in areas with significant pollution, the filter
element must be changed between the specified service dates.
Key recognition
The current climate control settings are automatically stored and
assigned to the key being used. The settings assigned to the key are
restored automatically when the vehicle is started. These settings are
different when the power top is open or closed. Each driver can use
his or her preferred settings witho ut having to man ually adjust them
when using their own key.
If another driver changes the settings while using your key, your
prefer red sett ings will be erased.
Energy management
To prevent the battery from be ing discharged and to restore the
balance of energy, components which require large amounts of
energy are temporarily cut back or switched off=>
page 247. Heating
systems in partic ular require a great dea l of energy. If you notice, for
example, that the rear window heater is not heating , the n 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. .,,_
