Warm and cold

Climate control system

Description

Operation

One of the following options may be available,

depending on vehicle equipment:

– A deluxe automatic climate control system with

three zones where the temperature, air distri-

bution, and air supply can be set separately on

the left and right front sides, and the tempera-

ture can be set separately in the rear

– A deluxe automatic climate control system with

four zones to individually adjust the tempera-

ture, air distribution, and amount of ventilation

at all of the seats

Fig. 81 Center console: lower display and switch panel

Settings are adjusted using both displays, the

switch panel in the center console, and the con-

trol panel in the rear. For information on how to

operate the touch displays, see ðpage 21, Touch

displays.

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,

depending on vehicle equipment, the roof are

closed. If there is a build-up of heat inside the ve-

hicle, ventilation can help to speed up the cooling

process.

You can adjust all climate control system settings

in the front; only certain functions are available

in the rear.

Lower display

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.

The lower display has two sections with controls:

You can regulate the blower and the air distribu-

tion automatically using AUTO in area 1 . You can

also apply individual settings here.

Active combination filter

In area 2 , you can turn individual climate control

system functions on and off.

When the fan is running, the filter will reduce

particulate matter and the concentration of pol-

len, as well as odors in the interior.

cle to increase. This can have a negative ef-

fect on the well-being of vehicle occupants,

which can increase the risk of an accident.

Turn off recirculation mode or automatic re-

circulation and ventilate the vehicle at the

first sign of unwellness.

– 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 turning off the ignition and turning

it on again.

– Applies to: vehicles with fragrance function:

Only use the fragrance function in modera-

tion and take any passengers and animals

into consideration when using the function.

An overlap of different scents or odors could

cause discomfort. If there is discomfort, re-

duce the intensity or turn off the fragrance

function. Only use fragrances that are ap-

proved by Audi.

– The vehicle is equipped with functions to au-

tomatically activate the seat heating. To re-

duce the risk of burns, individuals with re-

duced sensitivity to pain or temperature

must make sure that the seat heating is off

when starting the drive.

– When the seat heating is on, an alternating

magnetic field is created. Interactions such

as irritation of sensory organs or malfunc-

tions of active medical implants (such as

pacemakers, infusion pumps, or neurosti-

mulators) are very unlikely. If you have a

medical implant, seek medical advice from a

specialist if you have any questions.

Adjusting the vents

You can open and close the vents using the

thumbwheels. The levers adjust the direction of

the airflow from the vents.
