The air distribution can adjusted with the but-
tons. To have the air distribution regulated auto-
matically, press the AUTO button.
The round air vents in the cockpit are adjustable
> page 68.
To keep the front side windows from fogging up
in damp weather, we recommend opening the
side air vents and tilting them to the side.
Foot vents are located under the front seats and
adjustable vents on the end of the center console
to heat the rear of the vehicle.
& Defrosting
The windshield and side windows are defrosted
or cleared of condensation as quickly as possible.
The maximum amount of air flows mainly from
the vents below the windshield. Recirculation
mode switches off. The temperature should be
set at +72°F (22°C) or higher. The temperature is
controlled automatically. In the & setting, the
A/C cooling mode switches on automatically, de-
pending on the outside air temperature.
The AUTO button switches the defroster off.
<> Recirculation mode
The recirculation mode can be turned on manual-
ly or automatically*.
— Switching manual recirculation mode on and
off: press the > button.
— Automatic* recirculation mode: auto recircula-
tion needs to be activated in the Infotainment
system. Select in the Infotainment system:
MENU] button > Vehicle > left control button >
Air conditioning > Auto recirculation. The air
quality sensor that is designed for diesel and
gasoline exhaust automatically switches the re-
circulation mode on or off depending on the
level of pollutants in the outside air.


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. Switching recirculation mode on
when driving through a tunnel or when sitting in
traffic is recommended > A.
Pressing the <> button, AUTO or the ® button
switches recirculation mode off.
@ Rear window heating
If the rear window defogger is activated when
the ignition is switched on, the battery manage-
ment determines based on the battery charge if
it is possible to turn on. Otherwise, the rear win-
dow defogger functions with the engine running
and switches off automatically after approxi-
mately 10 - 20 minutes, depending on the out-
side temperature.
To prevent the rear window defogger from
switching off automatically, press and hold the
® button for more than two seconds.
#/ Seat heating*
Pressing the a button switches the seat heating
on at the highest setting (level 3). The LEDs indi-
cate the temperature level. To reduce the tem-
perature, press the button again. To switch the
seat heating off, press the button repeatedly un-
til the LED turns off.
After approximately 10 minutes, the seat heating
automatically switches from level 3 to level 2.

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.


@) 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.
G) Tips
If the front passenger's seat heating is turned
on, it will not turn on again automatically if

Fig. 109 Front of vehicle: sensor
The radar sensor area > fig. 109 must not be cov-
ered with stickers, deposits or any other obstruc-
tions as it may impair the function of the adap-
tive cruise control or the pre sense front. For in-
formation on cleaning, see > page 342. The
same applies for any modifications made in the
front area.
The function of the adaptive cruise control sys-
tem or pre sense front is limited in some condi-
tions:
— Vehicles can only be detected when they are
within the sensor range > page 118, fig. 108.
—The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle or moving into your
lane.
— Objects that are difficult to detect such as mo-
torcycles, vehicles with high ground clearance
or an overhanging load are detected late or not
detected at all.
— When driving through curves > page 120.
— When the vehicle is stationary > page 120.


Z\ WARNING
Always pay attention to the traffic around you
when adaptive cruise control is switched on.
As the driver, you are still responsible for your
own speed and the distance to other vehicles.
The adaptive cruise control is used to assist
you. The driver must always take action to
avoid a collision. The driver is always responsi-
ble for braking at the correct time.
— For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan-
ing). Using the system under these condi-
tions could result in a collision.
— Switch adaptive cruise control off temporari-
ly when driving in turning lanes, on express-
way exits or in construction zones. This pre-
vents the vehicle from accelerating to the
stored speed when in these situations.
— The adaptive cruise control system will not
brake by itself if you put your foot on the ac-
celerator pedal. Doing so can override the
speed and distance regulation.
— Adaptive cruise control does not respond to
people, animals, or crossing or oncoming
objects.
— The function of the radar sensors can be af-
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice

@) Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can impair the adaptive
cruise control. Have an authorized Audi dealer
or authorized Audi Service Facility check their
function.

Audi pre sense
Introduction
Applies to: vehicles with Audi pre sense
Within the limits of the system, the pre sense
functions can initiate measures in particularly
dangerous situations to protect the vehicle pas-
sengers and other road users.
— Due to the interlinking of various vehicle sys-
tems, critical driving situations can be detected
by pre sense basic and measures for preventa-
tive occupant protection are can be initiated.
— The pre sense front uses the data from the ra-
dar sensors and calculates the probability of an
accident > page 119. An impending collision
with vehicles can be detected within the limits
of the system. In this case, the system warns
the driver visually, acoustically and with a jerk
on the brakes if necessary. If needed, it can ini-
tiate a partial or full deceleration to reduce the
collision speed or to avoid the collision under
certain circumstances. In conjunction with pre >
