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 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 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 off if the coolant temperature is
excessively high, to ensure adequate engine cooling under extreme
loads.
Pollution filter
The pollution filter (a particle filter) 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 system will temporarily shut off the
electrical components that are using a lot of power, or reduce the
current they are consuming ⇒page 202. 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.

Heating and cooling 102The 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.

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
and lead to an accident. Please familiarise yourself with the oper-
ating controls for the air conditioner, including the demist/defrost
functions for the windows.
Caution
•
If you suspect that the air conditioner is damaged, switch it off
to prevent further damage and have the system checked by a quali-
fied workshop.
•
Repairs to the air conditioning system require specialist knowl-
edge and special tools. For this reason, please contact a qualified
workshop if the system is not working properly.Note
•
Keep the air intake slots in front of the windscreen clear of snow,
ice and leaves to ensure unimpaired heating and cooling, and to
prevent the windows misting over.
•
The air from the outlets flows through the passenger compart-
ment and out through the slots at the rear of the vehicle. Do not
cover these slots with clothing or other objects.
•
The air conditioner operates most effectively with the windows
and the tilting panorama roof* closed. However, if the vehicle has
heated up after standing in the sun for some time, the air inside can
be cooled more quickly by opening the windows for a short time.

Auxiliary heating and auxiliary
ventilationApplies to vehicles: with auxiliary heating - under development at the time of printingDescription
The auxiliary heating and ventilation systems heat and
cool the interior independently of the engine.The auxiliary heating
works in conjunction with the air condi-
tioner system, but does not rely on heat from the engine. Instead of
this, the system burns fuel. The system's main function is to warm
up the interior of the vehicle and to defrost the windows in cold
weather.
The auxiliary heating system can be used both when the vehicle is
stationary and when driving (to provide extra heat while the engine
is warming up).
The auxiliary ventilation also operates independently of the
engine. This feature can be used to cool the interior with the blower
when the vehicle is left parked in the sun.
The system will automatically activate either the auxiliary heating or
the auxiliary ventilation mode, depending on the actual tempera-
ture measured inside the car and the temperature you have set with
the air conditioner controls. It is possible to alter the temperature
setting while the auxiliary heating/ventilation is running.
Switching on and off
There are two different ways of switching on the auxiliary
heating/ventilation system.
•
Immediate start: You can switch the auxiliary heating/ventilation
on and off at any time in the MMI Car menu ⇒page 112. You can
also switch the system on and off using the remote control
⇒page 114.
•
Switching on via timer: You can programme various start times
using the timers ⇒page 112. However you must first activate the timer before the auxiliary heating/ventilation system will switch on
automatically.
The auxiliary heating/ventilation will switch itself off at the end of
the programmed running time. The running time can be set to 15,
30, 45 or 60 minutes ⇒page 113.
WARNING
•
The auxiliary heating must not be allowed to run when the
vehicle is in a confined space because it can give off toxic fumes.
•
To avoid any possible fire risk, never have the auxiliary heating
switched on when refuelling the vehicle.
•
Because of the high temperatures which occur when the auxil-
iary heating is running, make sure when parking the car that the
exhaust outlet under the car is not obstructed in any way and that
the exhaust gases do not come into contact with flammable mate-
rials (fire risk).Note
•
It is advisable to open the air outlets when using the auxiliary
heating/ventilation.
•
The auxiliary heating/ventilation will not switch on if the fuel in
the tank has reached the reserve zone.
•
The auxiliary heating/ventilation will not switch on if the battery
charge level is low.
•
The symbols
(auxiliary ventilation) or
(auxiliary heating)
flash in the instrument cluster next to the clock display when the
auxiliary heating/ventilation is switched on. Both symbols light
continuously when the timer is activated.
•
At low outside temperatures some visible water vapour may
form in the engine compartment. This is a normal phenomenon,
and no reason for concern.

When it is switched on, the auxiliary heating or auxiliary ventilation
starts immediately and remains on for the period set in the menu.
The maximum running time is 60 minutes.
If you want to switch the system on again after the end of the
programmed running time, press the button .
Transmitter indicator lamp
The transmitter indicator lamp will flash accordingly to show
whether the command you sent via the remote control was
successful.
When you switch the system on by pressing the button the
indicator lamp will flash green for about 30 seconds to confirm that
the heating/ ventilation has been switched on. When you switch the
system off by pressing the button the indicator lamp will
flash red to confirm that the heating/ ventilation has been switched
off.
If the remote control is outside the transmitting range the indicator
lamp will flash red slowly. If there is a fault in the system (e.g. fuel
level is down to reserve), the indicator lamp will flash red rapidly. In
both cases the command will not be executed.
When the remote control battery is almost completely flat, the
transmitter indicator lamp will not light up and no commands will
be executed.

Technical data Transmitting range
The range of the remote control transmitter is about 600 metres.
However, this can be greatly reduced by obstacles (buildings, etc.)
between the remote control transmitter and the vehicle. Hold the
aerial upright when using the remote control.
You should not normally use the remote control at a distance of less
than 3 metres from the vehicle. If you are closer than this, or if you
use the remote control inside the vehicle, this can cause signal over-
load.
