Deluxe automatic air conditioner plusApplies to vehicles: with deluxe automatic air conditioner plusDescription
The air conditioner is designed to keep the passenger
compartment at the temperature you find most comfort-
able at all times of the year.The air conditioner provides heating 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 101.
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 off if the coolant temperature is
excessively high, to ensure adequate engine cooling under extreme
loads.
Pollution filter
The pollution filter (a combined particle filter and activated charcoal
filter) serves as a barrier against impurities in the outside air,
including dust and pollen, and against unpleasant smells. 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.

– Press the button for the blower .
– Turn the rotary control to set the blower to the desired
speed (and regulate the volume of air delivery).The air conditioning system automatically regulates the blower
speed according to the interior temperature. However, you can also
adjust the blower speed manually.
The blower speed will be shown on the MMI display ⇒fig. 117 for a
few seconds if the MMI is switched on.
Note
•
The blower speed may change automatically. This ensures that
the selected temperature is reached as quickly as possible.
•
The blower speed cannot be regulated separately for the driver
and front passenger sides of the vehicle.
Applies to vehicles: with deluxe automatic air conditioner plusAir recirculation mode
The air recirculation setting prevents fumes etc. from
entering the interior.Switching on the air recirculation mode
– Press the button ⇒.
Switching off the air recirculation mode
– Press the button again, or
– Press the button, or
– Press the button.In this setting, the air is drawn from the interior of the vehicle,
filtered and continuously recirculated. We recommend using the air
recirculation mode in the following circumstances:
When driving through a tunnel or in queues of traffic, to prevent
fumes entering the interior of the vehicle.
WARNING
For reasons of safety you should not leave the air recirculation
switched on for too long. This mode prevents fresh air from
entering the vehicle, so the windows can mist over if the air
cooling is switched off. Bad visibility can cause an accident.

Technical data 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 conditioner plusAC mode Deactivating the AC mode
– Press the button.
Activating the AC mode
– Press the button again.In the AC mode, the air cooling system is switched on and the
heating and ventilation are regulated automatically.
Note
If the LED in the AC button should continue to light up when the AC
mode has been switched off (i.e. the air conditioner has been
switched off) this is due to a defect in one of the air conditioner
components. If a malfunction should occur, please contact a quali-
fied workshop.

The air distribution setting directs the air to the outlets
you select.Fig. 120 Dashboard: Location of air outletsAir outlets and
– The outlets can be opened and closed by turning the
thumbwheels next to them.
– The direction of air delivery from these outlets can be
adjusted horizontally and vertically using the adjuster in
the centre of each outlet grille.The flow of air from the outlets is controlled either automatically or
manually, depending on the operating mode selected. Outlets to
can provide air which is either heated, unheated, or cooled.

Applies to vehicles: with deluxe automatic air conditioner plusAutomatic recirculation
If the outside air is polluted, an air purity sensor in the
vehicle will automatically switch on the air recirculation.To prevent fumes, etc. in the outside air from entering the interior,
we recommend that the automatic air recirculation should be
switched on at all times.
If the air purity sensor in the air conditioner system detects a certain
concentration of fumes in the outside air, the control unit will either
pass the incoming air through the pollution filter or automatically
switch on the air recirculation. If there is a high concentration of
pollution in the outside air, the air conditioner automatically
switches to air recirculation and cuts off the supply of air from the
outside. As soon as the level of pollution decreases, air is fed into
the vehicle from the outside again.
If the windows mist up when the automatic air recirculation is on,
press the
 button immediately.
