Doors and windows
44Data stored on remote control key
Data related to the service and maintenance of the vehicle are
stored continuously on your remote control key. Your Audi dealer
can read out the data and will then be able to tell you what service
work is required. This also applies to vehicles with advanced key.
Personal convenience settings
If two people use the same car regularly, it is a good idea for each
person to have his or her “own” remote control key. When you
switch off the ignition or lock the vehicle, your personal settings for
the following convenience features are stored and assigned to the
remote control key:•
Air conditioner
•
Central locking system
•
Windows
•
parking system*
•
adaptive cruise control*
•
Audi drive select*
•
Seat memory*
The stored settings are then recalled automatically the next time the
vehicle is unlocked, the doors are opened or the ignition is switched
on.
WARNING
•
Always take the key with you when leaving the vehicle - even if
you only intend to be gone for a short time. This is especially
important if children are left in the car. They might otherwise be
able to start the engine or use power-operated equipment such as
the electric windows - this could lead to injuries.
•
Wait for the vehicle to come to a standstill before removing the
ignition key from the lock. Otherwise the steering lock could
engage suddenly, causing an accident.
Note
The function of the remote control key may be impaired by interfer-
ence from other nearby radio sign als (for example from a mobile
telephone or TV transmitter) if these are in the same frequency
range.Indicator lamp on remote control key
The indicator lamp on the remote control key lights up
when you press the buttons.The indicator lamp should light up once briefly when you press one
of the buttons briefly. The indicator lamp should flash when you
press and hold one of the buttons (convenience open/close).
If the indicator lamp does not li ght up, this means the battery is
exhausted and must be replaced ⇒page 45 . The instrument cluster
display also sh ows the symbol
 and the following message if the
battery is exhausted:
Please change key battery

Technical data
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

94and lead to an accident. Please fa miliarise 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 Audi air conditioner require specialist knowledge
and special tools. For this reason , please contact a qualified work-
shop 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 cl othing 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.

– Press the button to switch off the air conditioner and cut off the supply of fresh air from outside the
vehicle.The air conditioner will switch on again if one of the control buttons
is pressed.
Applies to vehicles: with deluxe automatic air conditionerAutomatic mode
The standard operatin g mode for all seasons.Switching on automatic mode
– Select a temperature between +16 °C (60 °F) and +28 °C
(84 °F).
– Press the button.The automatic mode maintains a constant temperature inside the
vehicle and dehumidifies the air. Air temperature, air delivery and
air distribution are regulated automatically to reach the desired
interior temperature as quickly as possible, and then to maintain
this temperature. The system automatically compensates for any
variations in the outside temperature and for the effect of direct
sunlight.
The automatic temperature regulation only operates at temperature
settings between +16 °C and +28 °C. If a temperature below +16 °C
is selected, LO appears on the display. If a temperature above +28 °C
is selected, the display will show HI. In the two extreme settings the
air conditioner operates continuo usly with maximum cooling or
heating output, and the temperature is not regulated
automatically.

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 conditionerAir recirculation mode
The air recirculation setting prevents fumes etc. from

– 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.
