Roof carrierApplies to vehicles: with roof carrier: Under development at the time of printDescription
Additional loads can be transported using the roof carrier.Note the following points if you in tend to carry loads on the roof:•
The rain channels are moulded into the roof as part of the aero-
dynamic roof design. It is therefore not possible to mount conven-
tional roof luggage racks. We recommend using the carrier units
from the range of Audi Genuine accessories.
•
These carrier units form the basic elements of a complete roof
carrier system. Special fixtures must then be added in order to
safely transport luggage, bicycles, sk is, surf boards or boats on the
roof. All the elements of this syst em are available from Audi dealers.Caution
Any damage to the vehicle caused by the use of other types of roof
rack or incorrect installation will not be covered by the factory
warranty. The roof carrier system mu st therefore be installed exactly
according to the instructions provided.

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

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.
