climate control
Description
The climate con trol system warms, coo ls and re ­
moves humidity from the air in the vehicle inte ri­
or. It is the most effective when the w indows and
sunroof* are closed. If there is a bu ild-up of heat
i n side the veh icle, ven tilat ion can he lp to speed
up the cooling process .
In a ll heating mode functions, except for defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a sufficient tem­
perature.
Pollutant filt er
The po llutant filter removes pollutants such as
d ust and pollen from the air.
Key recognition
The clima te control settings are automatically
s tored and assig ned to th e remo te contro l key
that is in use.
& WARNING
Poo r visibility can lead to accidents.
- For safer d riving, keep all windows free of
ice, snow and fo g.
- B ecome familia r as quickly as possible wi th
the correct use and function of the cl imate
contro l system, especially with the defrost­
ing and defogging function.
- When the temperat ure is below freezing,

N .... 0 0 :c ' @ Tips
-Some noise after starting the engine is nor­
mal and is no cause for concern.
- If you leave the vehicle with the ignition
switched on, the ignition will switch off af­
ter a certain amount of time. Make sure that
electrical equipment such as the exterior
lights are switched off.
Stopping the engine
"'Bring the vehicle to a full stop.
"'Select the P or N selector lever position.
"'Press the
I START ENGINE STOPI button
r::?v page 76, fig. 90.
Steering lock
The steering locks when you turn the engine off
using the
I START ENGINE STOPI button and
open the driver's door. The locked steering helps
prevent vehicle theft.
Emergency off function
If it is absolutely necessary, the engine can also
be turned off while driving in the R, Dor S selec­
tor lever position at speeds below 6 mph (10 km/
h). To stop the engine, press and hold the
I START ENGINE STOPI button and also press the
brake pedal.
& WARNING
-Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You must use
more force to turn or brake. Because you
cannot steer and brake as you usually
would, this could lead to accidents and seri­
ous injuries .
- Always take the key with you whenever you
leave your vehicle. Otherwise, the engine
could be started or electrical equipment
such as the power windows could be operat­
ed. This can lead to serious injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Driving
Otherwise, there is the risk that the vehicle
could roll unintentionally.
@ Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off.
(D Tips
After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched off .
It can also switch on again after some time if
the coolant temperature rises as the result of
heat buildup or if the engine is already warm
and the engine compartment is also heated
by the sun's rays.
Messages in the instrument cluster display

This indicator light turns on and this message ap­
pears if the ignition key was removed from the
vehicle when the engine was running. If the igni ­
tion key is no longer in the vehicle, you cannot switch on the ignition or start the engine once
you stop it. You also cannot lock the vehicle from
the outside.
Shift to P, otherwise vehicle can roll away.
Doors do not lock if lever is not in P.

Driving
During emergency braking, your vehicle will
brake similar to heavy braking. ESC and the
associated components (ABS, ASR, EDL)
cannot overcome the laws of physics. In cor­
ners and when road or weather conditions
are bad, a full brake application can cause
the vehicle to skid or the rear end to swerve,
which increases the risk of an accident.
- If the power supply fails, you cannot set the
parking brake if it is released. In this case,
park the vehicle on level ground and secure
it by placing the selector lever in the P posi­
tion. See an authorized Audi dealer or au­
thorized Audi Service Facility for assistance.
- Always take the vehicle key with you when leaving your vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle . Otherwise chil­
dren could start the engine, release the
parking brake or operate electrical equip­
ment such as power windows, which in­
creases the risk of an accident.
- No one should remain in the vehicle when it is locked -especially children. Locked doors
make it more difficult for emergency work­
ers to get into the vehicle, which puts lives
at risk.
(D Tips
When stopping at a traffic signal or stopping in city traffic, you can set the parking brake
manually. The vehicle does not have to be
held with the brake pedal. The parking brake
eliminates the tendency to creep when a se­
lector lever position is engaged. As soon as
you press the accelerator pedal, the parking brake releases automatically and your vehicle
starts to move
c> page 82.
(D} Tips
-Occasional noises when the parking brake is
set and released are normal and are not a
cause for concern.
- The parking brake goes through a self-test
cycle at regular intervals when the vehicle is
stopped. Any noises associated with this are normal.
82
- If there is a power failure, the parking brake
will not set if it is released, and it will not release if it is set ¢&. . See an authorized
Audi dealer or authorized Audi Service Fa­ cility for assistance .
Starting from a stop
Various convenience and safety functions may be
available when the vehicle begins driving, de­
pending on vehicle equipment .
Starting on hills with the parking brake set
Requirement: the driver 's door must be closed
and the driver's safety belt must be fastened.
.,. To start driving comfortably when on a hill, set
the parking brake and begin driving as usual.
The braking force of the parking brake does not
release automatically until the wheels build up
enough driving force.
Starting on hills with hill hold assist
Hill hold assist makes it easier to start on hills.
Requirement: the driver's door must be closed
and the engine must be running.
.,. To activate hill hold assist, press and hold the
brake pedal for several seconds. The vehicle
must be in an uphill direction of travel.
After releasing the brake pedal, the braking pow­
er is maintained for a brief moment
c> &. to pre ­
vent the vehicle from rolling back when starting.
During this time, you can easily begin to move
your vehicle.
&_ WARNING
A ppl ies to: ve hicles with hill hold assist
- If you do not begin driving immediately or
the engine stalls after releasing the brake
pedal, your vehicle may begin to roll back­
ward. Press the brake pedal or set the park­
ing brake immediately .
- The intelligen t technology of hill hold assist
cannot overcome the limitations imposed by
natural physical laws. The increased comfort
offered by hill hold assist should not cause
you to take safety risks .

Intelligent Technology
To restore the balance of energy, components
that require large amounts of energy are tempo­
rarily scaled back or switched off. Heating sys­
tems in particular require a great deal of energy .
If you notice, for example, that the seat heating"
or rear window defogger is not working, then it has been temporarily reduced or switched off .
These systems are available again as soon as the
energy supply has been restored.
In addition, you may notice that the idle speed
has slightly increased. That is normal and no
cause for concern . By increasing the idling speed,
the additional requ ired energy will be generated
and the vehicle battery will be charged.
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This vehicle is equipped with an Event Data Re­
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa­
tions , such as an airbag deployment o r hitting a
road obstacle, data that will assist in understand­
ing how a vehicle 's systems performed. The EDR
is designed to record data related to vehicle dy­
namics and safety systems for a short period of
time, typically 30 seconds or less. The EDR in this
vehicle is designed to record such data as :
- How various systems in your vehicle were oper­
ating;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can help prov ide a better understand­
ing of the circumstances in which crashes and in­
juries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs ;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g.,
name, gender, age, and crash location) are re­
corded. However, other parties, such as law en-
132
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
To read data recorded by an EDR, special equ ip­
ment is required, and access to the vehicle or the
EDR is needed . In addition to the vehicle manu­
facturer, other part ies, such as law enforcement,
that have the special equipment, can read the in­
formation if they have access to the vehicle or the
EDR .
Some state laws restrict the retrieval or down­
loading of data stored by ED Rs installed in a vehi­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own ­
er 's consent .
Audi will not access the EDR and/or simi lar data
or give it to others -
- unless the vehicle owner (or lessee if the vehi ­
cle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsuit through the judicial
discovery process.
- Audi may also use the data for research about
veh icle operation and safety performance or
provide the data to a third party for research
purposes without identifying the specific vehi­
cle or information about the identity of its own ­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emission control, airbags, and safety belts.
These electronic control modules record data during normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capability of these
modules is limited to data (no sound is record­
ed) . Only a small amount of data is actually re­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a contro l
module . Some of the data stored may relate to .,._
