Coolant temperature
display
The coolant temperature display @) > page 12
only functions when the ignition is switched on.
To reduce the risk of engine damage, please ob-
serve the following notes about the temperature
ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem-
perature yet. Avoid high engine speeds, full accel-
eration, and heavy engine loads.
Normal range
The engine has reached its operating tempera-
ture once the LEDs up to the center of the gauge
turn on. If the Bg indicator light in the instru-
ment cluster display turns on, the coolant tem-
perature is too high > page 249.
@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.
— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.

Warm and cold

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.
G) 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.

— 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.

Warm and cold

Applies to: vehicles with 4-zone automatic cli-
mate control: You can press J in the rear control
panel multiple times to adjust the air distribution
based on the direction of the arrow.
® Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
Align the outer air vents with the side windows.
The maximum amount of air flows mainly from
the vents below the windshield. The windshield
defogger” is also switched on at low outside tem-
peratures. The ® button will flash. Recirculation
mode switches off. The temperature should be
set at 72 °F (+22 °C) or higher. Depending on the
outside temperature, the A/C cooling mode may
automatically switch on.
& Rear window defogger
The rear window defogger only operates when
the engine is running. It switches off automati-
cally after 10 to 20 minutes, depending on the
outside temperature.
To prevent the rear window defogger from
switching off automatically, press and hold the
& button for more than three seconds. It will re-
main on until the ignition is switched off.
AUTO
<>/cS Recirculation mode
In recirculation mode, the air inside the vehicle is
circulated and filtered. This prevents the unfil-
tered air outside the vehicle from entering the
vehicle interior > A\.
Pressing <> switches recirculation mode on or
off manually.
AUTOX
When switched on, automatic recirculation controls the recirculation mode automatically.
You must press the ¥ button if fog forms on the
windows.
« Seat heating
Applies to: vehicles with heated seats
The seat heating temperature can be set at mul-
tiple levels. Press 4 once to switch on the highest
level. Press «) again to decrease the temperature
one level at a time. The seat heating is switched
off if the button is not illuminated.
®) Seat ventilation
Applies to: vehicles with seat ventilation
The seat ventilation intensity can be set to multi-
ple levels. Press 2) once to switch on the highest
level. Press 2) again to decrease the heat level
one level at a time. The seat ventilation is switch-
ed off if the button is not illuminated.
@ Child safety lock*
If 8 turns on in the control panel in the rear, the
child safety lock is active and operation is blocked
=> page 46.
§ Ionizer
Applies to: vehicles with ionizer
Hazardous particles and germs in the air may be
reduced through ionization. This helps to im-
prove the air quality for individuals in the passen-
ger compartment.
&" Fragrance
Applies to: vehicles with fragrance function
The fragrance function will dispense a scent in
the vehicle interior. It is dispensed through the
front outer vents. This will produce a pleasant
scent. The fragrance is time-delayed, especially
at low or high temperatures. You can adjust the
fragrance function > page 94.
Residual heat
The residual heat from the coolant is used to
heat the vehicle interior. To use this function,
press and hold the &% button for more than two
seconds while the ignition is switched off. The
function switches off automatically after about
15 minutes.

ZX 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*.
