Heating and coolingDeluxe automatic air conditionerApplies to vehicles: with deluxe automatic air conditionerDescription
The air conditioner can be used to set a comfortable inte-
rior temperature in the vehicle.The air conditioner provides heatin g and ventilation and also cools
and dehumidifies the air inside the vehicle.
The air conditioner is fully automatic and will maintain the desired
temperature at a constant level. To achieve this, the temperature of
the air supplied to the interior, the blower speed (volume of air
delivery) and the air distribution are regulated automatically. The
system also allows for the effect of strong sunlight, so there is no
need for manual adjustment. For these reasons it is advisable to use
the automatic mode for the comfort of all the passengers in virtually
all conditions throughout the year ⇒page 95 .
Please note:
The humidity of the air is automatically reduced when the system
cools the interior of the vehicle. This helps to prevent condensation
on the windows.
If the humidity and temperature outside the vehicle are high,
condensation can drip off the evaporator in the air cooling system
and form a pool underneath the vehicle. This is normal and does not
indicate a leak.
If the outside temperature is low, the blower normally only switches
to a higher speed once the coolant has warmed up sufficiently (this
does not apply to the defrost setting).
In order to achieve maximum engine power, the air conditioner
compressor is temporarily switched off when pulling away from a
standstill with full throttle. The compressor also switches of
f if the coolant temperature is
excessively high, to ensure adequate engine cooling under extreme
loads.
Pollution filter
The pollution filter (a particle filt er) serves as a barrier against impu-
rities in the outside air, including dust and pollen, and odours. The
air is also filtered when the air recirculation mode is activated.
For the air conditioner to work with maximum efficiency, the pollu-
tion filter element must be replaced at the intervals specified in the
Service Schedule.
If the vehicle is driven in areas with a high level of air pollution and
the filter is no longer fully effective, it may be necessary to change
the filter element more frequently.
Key-coded settings
The currently selected air conditioner settings are automatically
stored and assigned to the remote control key.
Power management
To prevent the battery from becoming discharged and to maintain
the necessary power level, the syst em will temporarily shut off the
electrical components that are usin g a lot of power, or reduce the
current they are consuming ⇒page 226 . Heating systems in partic-
ular use a large amount of electrical power. If you notice, for
instance, that the rear window heater is not working, it may have
been temporarily switched off by the power management function,
or regulated to a lower heat output. These systems will be available
again as soon as sufficient electrical power is available.
WARNING
For safety reasons it is important that all the windows are kept
free of ice, snow and condensation. These can cause poor visibility

wish to activate. In setting
 all the air is directed to the windows,
in setting
 the air is directed to the driver (or passenger), and in
setting
 to the footwells. In addition to this there are several other
possible combinations, allowing you to adjust the air distribution to
suit individual requirements.
Switch to for automatic control of the air distribution.
The air distribution setting will be shown on the screen ⇒page 97,
fig. 109 for a few seconds if the sound system or MMI* is switched
on.
Applies to vehicles: with deluxe automatic air conditioner Defrosting
The windscreen and side windows are defrosted or
demisted as quickly as possible.– To switch on, press the button.
– To switch off, press the button again, or press the button.The temperature is regulated automatically. The air output is
increased to maximum and most of the air comes out of the outlets
below the windscreen.
The air recirculation mode is switched off when the button is
pressed.Applies to vehicles: with deluxe automatic air conditioner Heated rear window
The rear window heating helps to demist the rear window.– Press the

b u t t o n t o s w i t c h t h e r e a r w i n d o w h e a t i n g o n
and off.
The rear window heating only works when the engine is running. An
indicator lamp in the button lights up when the rear window heater
is switched on.
Depending on the outside temperat ure, the rear window heating
switches off automatically after about 10 to 20 minutes.
The rear window heating can be switched on permanently by
pressing the
 button for longer than two seconds. It will then
remain on until the ignition is switched off. When the rear window
heating is switched on, this setting will remain activated for 15
minutes after switching off the ignition.
If the engine is started again during this period of 15 minutes, the
rear window heating will be switched on for about 10 to 20 minutes,
depending on the exterior temperature. This means you do not have
to manually switch on the rear window heating again if the vehicle
has only been parked for a short time.
For the sake of the environment
Switch off the heated rear window manually as soon as the rear
window is clear. By saving electrical power you can also save fuel.Applies to vehicles: with deluxe automatic air conditionerAC mode Deactivating the AC mode
