Warm and cold
Climate control system
One of the following options may be available,
depending on vehicle equipment:
— A deluxe automatic climate control system with
3 zones where the temperature, air distribu-
tion, and air supply can be set separately on the
left front side, the right front side, and in the
rear
— A deluxe automatic climate control system with
4 zones to individually adjust the temperature,
air distribution, and amount of ventilation at all
of the seats
The climate control system warms, cools, dehu-
midifies, and filters the air in the vehicle interior.
It is the most effective when the windows and
panoramic glass roof* are closed. If there is a
build-up of heat inside the vehicle, ventilation
can help to speed up the cooling process.
The deluxe climate control system automatically
maintains a temperature once it has been set. In
all heating mode functions except defrost, the
blower only switches to a higher speed once the
coolant has reached a certain temperature.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
@ For the sake of the environment
Energy can be saved by switching off the A/C
mode.
@ Tips
— To prevent interference with the heating or
cooling output and to prevent the windows
from fogging over, the air intake in front of
the windshield must be free of ice, snow,
and leaves.
— Condensation from the cooling system can
drip and form a puddle of water under the
vehicle. This is normal and does not mean
there is a leak.
100
— The energy management system may tem-
porarily switch off certain functions, such as
the seat heating” or rear window defogger.
These systems are available again as soon as
the energy supply has been restored.

Z\ WARNING
— You should not use the recirculation mode
for an extended period of time, because no
fresh air is drawn in and the windows can
fog when cooling mode is switched off. This
increases the risk of an accident.
— Individuals with reduced sensitivity to pain
or temperature could develop burns when
using the seat heating* function. To reduce
the risk of injury, these individuals should
not use seat heating*.
G) Note
To reduce the risk of damage to the seat heat-
ing* elements, do not kneel on the seats or
place heavy pressure on one area of the seat.
@ Tips
— If the front passenger's seat heating” is
turned on, it will not turn on again automat-
ically if more than 10 minutes have passed
between switching the ignition off and on
again.
— Only use the fragrance function* in modera-
tion and take any other passengers and ani-
mals into consideration when using the
function. An overlap of different scents or
odors could cause discomfort. If there is
discomfort, reduce the intensity or switch
the fragrance function* off. Only use fra-
grances that are approved by Audi.
