Deluxe automatic climate control
Applies to vehicles : wit h deluxe automat ic climat e cont ro l
Description
The climate control system can be used to set a comfort­
able temperature inside the vehicle.
The climate control system is a combination of a heating and ventila­
tion system as well a cooling system responsible for dehumidifying
and cooling the air inside the vehicle.
Th e automatic climate control system automatically maintains a
temperature once it has been set. The temperature of the air from
the vents, fan speed (air volume) and air distribution are a lso auto­
matically adjusted. The system also takes into account strong
sunlight so that manual adjustment is not necessary . So in almost all
cases,
automatic mode offers the best conditions for the comfort of
the occupants at all times of the year=>
page 97.
Please note the following :
The cooling mode lowers the humid ity level inside the vehicle. This
prevents fogging up of the windows.
In the case of high outside humidity and temperatures,
condensation
can drip from the air conditioning system evaporator and form a pool
under the vehicle . This is normal and not an indication of leaks!
At low outside temperatures, the fan automatically switches to a
higher speed when the coo lant reaches a sufficient temperature
except in the defroster position .
When starting with fu ll thrott le, the compressor of the automatic
climate control system is temporarily switched off to achieve full
eng ine power .
T o ensure engine cooling when the engine is under an extreme load,
the compressor is switched off at high coolant temperatures.

Warm and cold
Pollutant filter
The pollutant fi
lter (particle filter) ensures that impurities in the
outs ide air (e.g. dust, pollen) and odors are significantly reduced or
stopped . The air is also filtered in recirculation mode.
T he pollutant filter e lement must be changed at the intervals speci­
fied in the service plan so that the performance of the automatic
climate contro l system is not impaired.
If the effectiveness of the filter dec reases prematurely due to opera­
tion of the vehicle in areas with significant pollution, the filter
element must be changed between the specified service dates.
Key recognition
Th e cur rent automatic clima te control settings are automatically
stored and assigned to the master key.
Energy management
To prevent the battery from being discharged and to restore the
balance of energy, components which require large amounts of
energy are temporarily cut back or switched off=>
page 243. Heating
systems in particular require a great deal of energy. If you notice , for
example, that the rear window heater is not heating, then it has been
temporarily reduced or switched off by
energy management . These
systems are available again as soon as the energy balance has been
restored.
& WARNING
Traffic safety requires all window s to be clear of ic e, snow, and
condensation. Only then can good visibility be ensured . Famil­
iarize yourself with the correct operation of the automatic climate
control system as well as the proper procedure for defog-
ging/defrosting the windows. _,.

0 Note
• If you suspect that the cl imate contro l system has been damaged,
switch the system off to avoid further damages, and have i t inspected
by a qua lified dealersh ip. •
Repairs to the Audi a ir conditioner require special techn ica l knowl­
edge and special tools . Co ntact an a uth orized Audi dealer fo r assis­
tance .
(I] Tips
• To avoid adversely affecting heating and cooling performance and
to prevent condensation on the windows, the air intake in front of the
w indshield must be free of ice, snow and leaves.
• Th e air flowing out of the vents and througho ut the veh icle's
entire inter ior is discharged at the rea r of the vehicle . Make su re that
the o utlet s lots are not covered by clothing, etc.
• Climate control works most effective ly if the windows and the
panoramic sliding/tilt ing sunroof * are closed. However, if the interior
of a parked vehicle is extremely hot from the sun, briefly opening the
windows can speed up the cooling process. •

_____ o_ n_ t_h _e_ r_o _a _ d ________________________________________________ _
When stopping at a traffic signal or stopping in city traffic on vehicles
with an automatic transmission, the parking brake can be applied.
The vehicle does not have to be held with the footbrake . The parking
brake eliminates the tendency to creep with a drive range engaged.
As soon as you drive
off as usual, the parking brake is released auto ­
matically and the vehicle starts to move.
Starting on slopes
When starting on inclines, the starting assist prevents the vehicle
from unintentionally rolling back. The braking force of the parking
brake is not released until sufficient driving force has been built up at
the wheels .
[I) Tips
For safety reasons, the parking brake is released automatically only
when the driver 's safety belt is engaged in the buckle. •
Starting off with a trailer
To prevent rolling back unintentionally on an incline, do
the following:
- Keep the switch pulled and depress the accelerator. The
parking brake stays applied and prevents the vehicle from
rolling backward.
- You can release the switch once you are sure that you are
developing enough driving force at the wheels by
depressing the accelerator.
Depending on the weight of the rig (vehicle and trailer) and the
severity of the incline, you may roll backwards as you start. You can
prevent rolling backwards by holding the parking brake switch pulled
out and accelerating -just as you would when starting on a hill with a
conventional hand brake. •
Emergency braking
In the event that the conventional brake system fails or
locks.
- In an emergency, pull the switch and continue to pull it to
slow your vehicle down with the parking brake .
- As soon as you release the switch or accelerate, the
braking process stops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking function is initiated. The vehicle is
braked at all four wheels by activating the hydraulic brake system.
The brake performance is similar to making an emergency stop:::>& .
In order not to activate the emergency braking by mistake, an audible
warning tone (buzzer) sounds when the switch is pulled. As soon as
the switch is released, or the accelerator pedal is depressed, emer­
gency braking stops.
& WARNING
Emergency braking should only be used in an emergency, when
the normal foot brake has failed or the brake pedal is obstructed.
Using the parking brake to perform emergency braking will slow
your vehicle down as if you had made a full brake application. The laws of physics cannot be suspended even with ESP and its associ­
ated components (ABS, ASR, EDS). In corners and when road or
weather conditions are bad, a full brake application can cause the
vehicle to skid or the rear end to break away· risking an accident. •
Driver messages in the instrument cluster
Warning Vehicle incline is excessive
This message appears when the parking brake is applied on an incline
that exceeds about 30%. ._

may vary, depending on the type of display in your vehicle. The indi­
cator ligh t
CRUISE (US model)/ 0" (C anadia n mo del) w ill also light up
in the instrume nt cluster .
The speed is kept constant by modifying engine power or through an
active brake intervention.
& WARNING
• Always pay attention to the traffic around you when the cruise
control is in operation . You are always responsible for your speed
and the distance between your vehicle and other vehicles.
• For reasons of safety, cruise control should not be used in the
city, in stop-and-go traffic, on twisting roads and when road
conditions are poor (such as ice, fog , gravel, heavy rain and hydro­
planing) -you could have an accident.
• Switch the cruise control off temporarily when driving in
turning lanes, highway exits or in construction zones.
• Please note that unconsciously "resting" your foot on the
accelerator pedal causes cruise control not to brake. This is due to
the control system being overridden by the driver's acceleration.
(I) Tips
• Vehicles with manual transmission: You can attain the set speed
only if the gear that is currently engaged will allow it, or if it does not
tax the engine and allows it to run smoothly. Therefore shift into a
hig her o r lower gear in a t imely manne r.
• The brake lights illuminate as soon as the brakes apply
automatically .•
Changing speed
- Press the lever in the direction of the 0 => page 119,
fig. 110 or in the dire ction of the Oto increase or
decrease your speed . -
Let go of the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing the
lever. If you keep the lever pressed down, you will alter your speed in
S mph
(10 km/h) increments.
You can also press the accelerator pedal down to increase your speed,
e.g. if you want to pass someone. The speed you saved earlier will
resume as soon as you let off of the accelerator pedal.
If, however, you exceed your saved speed by 5 mph
(10 km/h) for
longer than 5 minutes, the cruise control will be turned off tempo­
rarily. The green symbol in the d isp lay turns white, the saved speed is
reta ined. •
Pre-selecting speed
You can pre -select your desired speed while the vehicle is
not moving.
- Turn on the ign ition .
- Pull lever into position 1
:::> page 119, fig. 110.
- Press the lever in the
0 or O direction to increase or
decrease your speed.
- Let go of the lever to save that speed.
This function makes it possible, for example, to save the speed you
want before dr iv ing on the highway. Once on the highway, activate
the cruise control by pulling the lever toward

Adaptive cruise control -____________ __._ __ _
& WARNING (co ntinued )
• Always turn off adaptive crui se control when entering turn
lanes, highway ex it lanes and con struction zones or similar situa­
tions because the vehicle will automatically accele rate to the
stored speed .
• Never rest your foot on the accelerator pedal, especially when
the adaptive cruise control is being u sed because doing so will
override the braking function and prevent the brakes from being
applied by the system when it detect s a situation when the brake s
must be applied.
• Alway s remember that the adaptive cruise control has limits -
it does not react when you drive towards an obstacle or something
else on or near the road that is not moving, such as vehicles
stopped in a traffic jam , a stalled or disabled vehicle .
• Always remember that the adaptive cruise control cannot
detect a veh icle th at i s driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and bicy­
cles .
[ i] Tips
• For safety reasons, the stored speed is deleted when the ignition
is turned off.
• The Electronic Stabilization Program (ESP) and the Ant i-Slip Regu ­
la tio n (A SR) c anno t be de activated when the adaptive cruise cont rol
is sw itched on .
If the ESP and the Anti -S lip Regulation (ASR) has been
de activ at ed an d yo u the n switch on the ad apt ive cruise cont rol, the
ESP fu nction w ill also be activated automatically.
• Dam age cau sed by accide nts (e.g. if the vehicle is dam age d whe n
park ing) can affect the rada r sensor settings. This can cause t he
sys tem to malfunc tion or switch off comple tely.
• The radar sensor cover is heated. In w inter conditions, you should
st ill ch eck befor e dr iv in g to make s ure i t is free of ice and s now. If
necessary, clean the area nea r the rada r sensor carefully=>
