General information
Appl ies to: ve hicles with per ip heral cameras
Fig. 145 Loca tion of peripheral c amera s
The four periphe ral cameras are located in the ra­
diator grille, in the luggage compartment lid and
on both exterior mirrors ¢
fig. 145 . Make sure
that the lenses are not covered by deposits or any
other obstructions as this may impair the system.
For information on cleaning, see¢
page 354.
Black corners are shown in the vehicle silhouette
in
Area mode . Objects in these areas are outside
of the camera's field of view and are not detect­
ed.
& WARNING
- Always read and follow the applicable warn­
ings ¢
.&. in General information on
page 136.
- If the position or the installation angle of a
camera was changed, for example after a
collision, do not continue to use the system
for safety reasons. Have it checked by an au­
thorized Audi dealer or authorized Audi Service Facility.
- Keep in mind that the image in the display is
incorrect if the exterior mirror housing has
been moved out of place .
- Use the
Rear mode and the corner view
(rear)
mode only when the luggage com­
partment lid is completely closed. Other­
wise the image in the display will be incor­
rect.
- The vehicle surroundings are shown using
the camera images . The vehicle image is
shown by the system. Objects and obstacles
above the camera are not displayed.
Parking systems
-Camera lenses enlarge and distort the field
of vision. The objects appear both altered
and inaccurate on the screen.
(D Note
- Always read and follow the applicable warn­
ings
¢ (Din General information on
page 136.
- The Infotainment display shows the direc­
tion in which the rear of the vehicle is travel­
ing based on the steering wheel angle. The
front of the vehicle swings out more than
the rear of the vehicle . Maintain plenty of
distance so that an exterior mirror or a cor­
ner of the vehicle does not collide with any
obstacles.
(D Tips
If the 8/fl;!J/c::5 symbol appears in the dis­
play and the respective display area is grayed
out, then the power exterior mirrors were
folded in or the driver's door/front passeng­
er's door/luggage compartment lid was
opened.

_& WARNING
-Always adapt yo ur speed to the weather,
road and traffic conditions. Do not let the
increased safety provided tempt you into
tak ing risks, because this increases the risk
of an accident.
-
-T he hill descent assist system cannot over­
come the laws of physics. Your driving style
must a lways be adapted to the current road
and traffic conditions.
- Hill descent assist may not be able to hold your vehicle at a constant speed under a ll
condit ions while driving on a hill (for exam­
ple if ground under the veh icle is loose) .
Brakes
New brake p ads
New brake pads do not ach ieve the ir full braking
effect during the first 250 mi (400 km). They
must be "broken
in" first. However, you can com­
pensate for the slightly reduced brak ing fo rce by
p ressing firmly o n the brake pedal. Avoid heavy
b raking during t he b reak-in per iod.
Wear
B rake pad
wear depends largely on the way the
veh icle is driven a nd on operat ing cond itions.
This is especia lly true if you are d riving frequently
in t he c ity and on c urves or wi th a sporty driving
style.
Operating noise
Noises may occur when braking depend ing on the
speed, braking force and outs ide cond itions such
as temperature and humidity .
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy ra in or after washing
your car, the brak ing effect may be reduced due
to moisture or ice on the brake rotors and brake
Intellig ent Technology
pads. The brakes m ust be "dried" first with a few
carefu l brake app lications.
At higher speeds and w ith the win dshield wipe rs
tu rned on, the brake pads press agains t the b rake
roto rs fo r a short amount of time. This action,
which is not felt by the driver, happens at regu lar
i nterva ls and ensures a better reaction t ime for
the b rakes in wet weather.
T he brak ing effec t can a lso be reduced if yo u are
driving on salted roads and yo u do not app ly the
brakes for long per iods of t ime. The layer of sa lt
on the brake rotors and pads m ust be worn off
first whe n the brakes are applied.
Corrosion
Leaving the vehi cle parked for long periods o f
time, low mileage and avoiding heavy b raking
can contrib ute to corros ion on the brake rotors
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if there is
corrosion present, occasiona l heavy braking at
high speeds is recommended to clean the brake
roto rs and
pads ¢~ -
Brake system malfunction
If you notice that the bra ke pedal trave l has sud­
denly increased, then a brake circuit in the dua l­
ci rcuit brake system may have malfunctioned.
Drive to an authorized Audi dealer or authorized
Audi Service Facility immed iate ly to have the
problem corrected. On the way there, drive w ith
reduced speed and keep in mind t hat you will
need a longer distance to stop and you will need
to press the bra ke ped al ha rder.
Low brake fluid level
When the bra ke fluid level is low, malfunctions in
the brake system may occur. The brake fluid level is elec tronically monitored.
Brake booster
The brake booster ampli fies the p ressure you ap-
ply to the brake pedal.

& WARNING
- Only apply the brakes for the purpose of
cleaning the brake system whe n road and
t raffic conditions perm it . You must not en­
dange r othe r road users . This increases the
risk of an accide nt.
- Never let the vehicle roll while the e ng ine is
stopped because this increases the risk of a n
a cci den t.
([) Note
- Neve r let the brakes " rub" by pressing the
pedal lightly when braki ng is not actually
necessa ry . T his ca uses the bra kes to over­
h ea t an d inc reases br akin g d istance an d
c a uses wear .
- B efo re driv ing downhill a long distance on a
steep hi ll, decre ase your spee d an d se lec t a
l ower gear . This makes use of t he engine
b raking effe ct and re lieves the brakes . If
you nee d to b rake additionally, b rake in in­
tervals and not continuously .
(D Tips

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 or 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
veh icle is designed to record such data as :
- How various systems in your vehicle were oper­
at ing;
- 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 he lp 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. Howeve r, other parties, such as law en­
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, specia l equip­
ment is required, and access to the vehicle or the
EDR is needed. In addition to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the specia l equipment, can read the in­
formation if they have access to the vehicle or the
EDR.
Some state laws restrict the retrieval or down­
l oading of data stored by ED Rs insta lled in a vehi ­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own­ er's consent.
Intelligent Technology
Audi will not access the EDR and/or simi la r data
or give it to others -
- unless the vehicl e 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 jud ic ial
discovery process.
- Aud i may also use the data for research about
veh icle operation and safety performance or
prov ide the data to a th ird party for research
purposes without ide ntify ing the specific vehi­
cle or information about the identity of its own­
er or lessee and only after the reco rded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped w ith a number of
electronic control modules for various vehicle
systems, such as engine management, emiss ion
contro l, airbags, and safety be lts.
T hese elect ronic contro l modu les record data
dur ing normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capab ility 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 control
module . Some of the data stored may relate to
vehicle speed, direction, or braking, as well as re­
straint system use and performance in the event
of a crash. Stored data can also only be read and
down loaded w it h special equipment that is di­
rectly connected to the vehicle .
(D Tips
Your vehicle may be equipped w ith Aud i con­
nect. Your use of certain Audi connect fea­
tures requires wire less services that are pro­
vided by a third party wireless telecommuni ­
cations provider . For details regarding how in­
formation obtained through Audi connect is
collected, processed, transmitted, used, and
shared, please see your contract with the
wireless telecommunications provider and the
