General information
Applies to vehicles: with rear pa rk in g systems/pa rk in g system
p lus/rearv iew camera
Depending on your vehicle's equipment, various
parking aids will help you when parking and ma­
neuvering.
The
rear parking system is an audible parking aid
that warns you of obstacles
behind the vehicle
¢page 152.
The parking system plus assists you when park ­
ing by audibly and visually indicating objects de­
tected
in front of and behind the vehicle
¢ page 152.
The rearview camera shows the area behind the
vehicle in the MMI display . This display assists
you when you are cross or parallel parking. The
parking system plus functions are also available
¢ page 153.
A WARNING ,--
- Always look for traffic and check the area
around your vehicle by looking at it directly
as well. The parking system cannot replace
the driver's attention. The driver is always
responsible when entering or leaving a park­
ing space and during similar maneuvers.
- Please note that some surfaces, such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
which people and objects cannot be detect­
ed . Be especially cautious of small children
and animals .
- Always pay attention to the area around the
vehicle -using the rearview mirror, too .
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The park ­
ing system may become impaired as a re­
sult. Have an authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
- Make sure the sensors are not obstructed by
stickers, deposits or other materials. If they
are the sensor function could be impaired .

@ Note
-Some objects are not detected or displayed
by the system under certain circumstances:
- Objects such as barrier chains, trailer draw
bars, vertical poles or fences
- Objects above the sensors such as wall ex­
tensions
- Objects with specific surfaces or struc­
tures such as chain link fences or powder
snow
- If you continue driving closer to a low-lying
object, it may disappear from the sensor
range . Note that you will no longer be
warned about this obstacle.
- The sensors can be displaced by impacts or
damage to the radiator grille, bumper,
wheel housing and the underbody . The
parking system may become impaired as a
result . Have an authorized Audi dealer or
authorized Audi Service Facility check their
function.
(D Tips
- The system may provide a warning even
though there are no obstacles in the cover­
age area in some situations, such as:
- certain road surfaces or for long grass .
- external ultrasonic sources e.g. from
cleaning vehicles.
- heavy rain, snow, or thick vehicle exhaust .
- We recommend that you practice parking in
a traffic-free location or parking lot to be­
come familiar with the system. When doing
this, there should be good light and weath­
er conditions .
- You can change the volume and pitch of the
signals as well as the display¢
page 157.
-What appears in the MMI display is some­
what time-delayed.
- The sensors must be kept clean and free of
snow and ice for the park assist to operate .

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Re corder
This vehicle is equipped wi th an Event Data Re ­
corder (EDR) . The main purpose of an E DR is to
record, in certain crash or near crash -like situa­
tions, such as an airbag deploym ent or h itting a
road obstacle, data that will assist in understand­
ing how a veh icle 's systems performed . The EDR
is designed to record data related to veh icle dy­
namics a nd safety systems for a sho rt period of
time, typically 30 seconds or less . The E DR in this
veh icle is designed to reco rd s uch 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
acce lerator and/or brake peda l; and,
- How fast the ve hicle was trave ling.
These data can help provide a better understand­ ing of the ci rc u mstances in which c rashes and in ­
juries occur. NOT E: EDR data are recorded by yo ur
veh icle only if a non-trivia l crash situat ion occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g .,
name, gender, age, and crash location) a re re­
corded . H owever , other pa rties , such as law en­
forcement, cou ld combine the EDR data w it h the
type o f person ally identifyi ng dat a routine ly ac­
qu ired dur ing a crash invest igat ion .
To read data reco rded by an EDR, specia l equip­
men t is req uire d, and access to the veh icle or the
E DR is needed. In ad dition to the vehicle manu­
facturer, other parties, s uch a s law enforcement,
that have t he specia l equipment, can read the in­
formation if they have access to the vehicle or the E DR.
Some s tate laws restrict the re trieva l or down­
loading of data stored by ED Rs insta lled in a vehi ­
cle fo r the express purpose of retrieving data af -
158
ter an accident or crash event withou t the own ­
er 's consent.
Audi will not access the EDR and /or sim ilar data
o r g ive it to others -
- unless t he ve hicle ow ner (o r lessee if the vehi­
cle has been leased) ag rees; o r
- upon the offic ial 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 icia l
discovery process.
- Audi may also use the data for research about
veh icle operation and safety perfo rmance or
prov ide the data to a th ird party for research
purposes w itho ut identify ing t he specific vehi­
cle or info rmat ion about the ident ity of its own­
er or lessee and only afte r th e re co rded vehicle
d ata has been a ccessed.
Vehicle control modules
You r vehicle is also equ ipped with a number of
e lectronic cont rol modules for va rious vehicle
syste ms, such as engine ma nagement, em iss io n
contro l, air bag s, a nd safety be lts.
These electronic control modules record data
dur ing norma l vehicle operation t hat may be
n eeded by tra ined techn ic ians for d iagnost ic and
r ep air pur poses. The re cording capab ility of these
modules is lim ited to dat a (no sou nd is recor d­
ed). Only a sma ll 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
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 a nd
down loaded w it h specia l equipment that is d i­
r ec tly connec ted to the vehicle.
(D Tips
Your vehicle may be e quipped w it h Aud i con­
n ect . Yo ur use of certain Aud i connect fea­
tures requires wire less services that are p ro­
v ided by a third party wireless telecomm uni­
cations provider. Fo r de tails regarding how in ­

Intelligent Technology
A WARNING
-New brake pads do not achieve their full
braking effect during the first 250 mi
-
(400 km). They must be "broken in" first .
However, you can compensate for the
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users. This increases the
risk of an accident.
- On steep slopes, reduce the speed and se­
lect a lower gear or lower selector lever po­
sition. Drive as little as possible while press­
ing the brake pedal and avoid putting your
left foot on the brake pedal while driving.
This could cause the brakes to overheat and
impair the efficiency of the brakes.
- Do not let the brakes "grind" by always
keeping your foot on the brake pedal. This
can cause the brakes to overheat, increase
wear and increase braking distance unneces­
sarily.
- Certain weather and operating conditions
such as driving through water, driving in heavy rain or driving after washing your ve ­
hicle can impair the effectiveness of the
brakes . In the winter, ice may build up on
the brake pads, rotors and drums. Check
these components by braking carefully. Ap­
plying the brakes carefully several times
dries the brakes and removes ice build-up .
- The efficiency of the brakes can also be im­
paired by driving for long stretches on roads
covered with salt without using the brakes.
You can remove salt deposits from the brake rotors and pads by carefully applying
the brakes several times.
- If the front spoiler is damaged or you install
another spoiler, make sure the front wheel brakes are ventilated properly . Otherwise,
the brake system could overheat, which re­
duces their effectiveness .
- Failure of a brake circuit impairs braking
performance, which increases braking dis -
162
tance. Avoid driving the vehicle and have it
towed it to the nearest authorized Audi
dealer or authorized Audi Service Facility.
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident .
- If the brake booster is not working, you will
have to press much harder on the brake
pedal to compensate for the lack of the
booster.
(D Note
- Never let the brakes "rub" by pressing the
pedal lightly when braking is not really nec­
essary. This causes the brakes to overheat
and increases braking distance and causes
wear .
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en­
gine braking effect and relieves the brakes.
If you need to brake additionally, brake in
intervals and not continuously.
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoil­
er, wheel covers or similar items, make su re
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the vehicle speed .
The vehicle still has full steering functionality if
the power steering fails or when the engine is
stopped (towing) . To steer, you must apply much
more force than usual. .,.

All wheel drive (quattro)
Applies to vehicles: with all wheel drive
In all wheel drive, all four wheels ore powered.
General information
In all wheel dr ive, the driving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as well as
the current road conditions . A lso see
c> page 159, Electronic stabilization control
(ESC).
The all whee l drive concept is designed for high
engine power. Yo ur vehicle is exceptionally pow­
erfu l and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions
c> ,&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, in winter we recommend using
winter or all season tires on
all four wheels, be­
cause this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on veh icles w ith all wheel dr ive
c> page 269, Snow chains.
Replacing tires
For vehicles with a ll wheel d rive, only wheels with
the same rolling circumference should be used .
Avoid wheels with different tread depths
c> poge 260.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficu lt terrain . Also see<=)
page 302.
A WARNING
--Also, in veh icles with all whee l drive, adapt
your driving style to the current road and
traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks.

0 > co ,...., Pyrotechnic saf ety belt pret ensioner s
The safety belts are equipped with safety belt
p re tensioners . The system is activated by sensors
in front, side and rear -end collisions of great se­
verity and in a rollover. This tightens the belt and
takes up belt slack
q & in Service and disposal of
safety belt pretensioner on page 183.
Taking up
the slack helps to reduce forward occupant
movement dur ing a coll is ion.
A WARNING
- It is possible for the pretensione rs to deploy
incorrectly.
- The pyrotechnic system can only prov ide
protection for one coll ision. If the pyrotech­
nic pretensione rs deploy, the pretens ion ing
system mus t be replaced.
The pyrotechnic safety belt pretens ioners can
only deploy once.
- The safety belt pretensioners do not dep loy
i n minor frontal, side and rea r-end colli­
s io ns.
- A fine d ust is released when the pyrotechnic
safety be lt pretens ioners deploy. This is nor­
mal and is not caused by a fire in the vehi­
cle.
- The re levant safety req uirements must be
obse rved w hen the ve hicle or components
of the system are sc rapped. A qualified
dealersh ip is familiar w ith these regu lations
and will be p leased to pass on the informa­
tion to you.
- Be sure to observe all safety, environmental and other regulations if the vehicle or indi­
vidual parts of the system, particularly the
safety be lt or airbag, are to be disposed. We
recommend you have your author ized Audi
dealer perform this serv ice for you.
Service and disposal of safety belt preten­
sioner
The safe ty belt pretens ione rs are pa rts of the
safety be lts on yo ur Audi. Installing, removing,
servicing or repairing of belt pretensioners can
S afet y be lts
damage the safety belt system and prevent it
from working correctly in a col lision .
T he re are some important things you have to
k now to make s ure tha t the effectiveness of the
system will not be impaired and that d iscarded
components do not cause injury or pollute the
environment.
A WARNING
-
Imp roper care, servicing and repair proce­
dures can increase the risk of personal in jury
and death by preventing a safety belt preten­
sioner from activating when needed or act i­
vating it unexpectedly:
- The belt pretensioner system can be activat­ ed only once. If belt pretens ioners have
been activated, the system must be re­
p la ced.
- Never repair, adjust, or change any parts of
the safety belt sys tem.
- Safety belt systems including safety belt
p retensioners cannot be repai red. Spec ial
p ro cedures are required fo r removal, instal­
lation and di$pO$al of thi$ $y$tem.
- For any wo rk on the safety belt system, we
s trong ly recommen d that you see yo ur au­
thor ized A udi dealer or qualified techn ician
who has an Audi approved repair man ual,
tra ining and special equipment necessa ry.

Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced A irbag System
pe rforms in a crash. For e xamp le, using t ire -r im
comb inations no t approved by Audi, lowering t he
veh icle, chang ing the stiffness o f the suspe nsio n,
i n cluding the springs, suspension struts, shock
absorbers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic contro l unit . Some suspens ion changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in c rashes in w hich it would not deploy if
the changes had not been made. Other ki nds of
200
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
_& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in­
crease the r isk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac­
ter istics as the components origina lly instal­
led on your vehicle.
- Never use tire-r im combinations that have
not been approved by Aud i.
