A WARNING
Following other vehicles too closely increases
the risk of coll isions and ser ious personal in­
jury.
- Setting short distances to the traffic ahead
reduces the t ime and distance available to
br ing your vehicle to a safe stop and makes
it even mo re necessary to pay close atten­
t ion to traffic.
- Always obey applicable traffic laws, use
good j udgment, and select a safe following
distance for the traffic, road and weather
condit ions .
@ Tips
- Di stance
3 is set automatically each time
you switch the ignition on.
- Your settings are automatically stored and
assigned to the remote control key being
used.

A ss ist
Request for driv er interv ent ion
Applies to: vehicles with Audi adaptive cruise control
F ig. 98 Instrument c luster: request for driver intervention
In certain situations, the system will request you
to take action:
- if the braking from the adaptive cruise control
system is not enough to maintain enough dis­
tance to the object ahead.
T he danger is indicated by the. indicator light
~ fig. 98. An aud io signa l will also sound.
- Press the brake pedal to slow your vehicle down.
Audi braking guard
Applies to: vehicles with Audi adaptive cruise control
Fig . 99 Instrument cluste r: approac h warning
The braking guard uses radar sensors and a v ideo
camera. It also f unctions w ith in t he lim its of the
system when adaptive cru ise control is switched
off.
What can the b raking guard d o?
When detected in time, the system can assess
dange rous situations where an object ahead
brakes sudden ly or if yo ur own vehicle is trave ling
at a high speed and approaching an object that is
II>

Assist
moving more slowly. The braking guard does not
react if it cannot detect the situation.
The system advises you of various dangerous sit­
uations:
- The
distance warning occurs if you drive too
closely to the object ahead for a long period of
time . If the object ahead brakes strongly, you
would not be able to avoid a collision. The.
indicator light appears as an indication for this.
- The
approach warning occurs when an object
ahead is traveling more slowly or brakes
strongly . When this warning occurs, it may only
be possible to avoid a collision by swerving or
braking strongly. The danger is indicated by the
• indicator light ¢
fig. 99. An aud io signa l will
also sound.
If you do not react early enough or at all to a dan­
gerous situation, the braking guard supports you
with a braking intervention.
- If a collision is imminent, the system will first
provide an
acute warning by braking sharply.
- If you do not react to the acute warning, the
braking guard can increase the braking force
within the limits of the system
1l. Th is reduces
the vehicle speed in the event of a co llision.
- The system can initiate complete deceleration
shortly before a collision
ll. Full deceleration at
high speeds occurs only in vehicles with adap­
tive cruise control and s ide assist (pre sense
plus).
- If the braking guard determines that you are
not braking strongly enough when there is an
impen ding collision, it can increase the braking
force .
- The pre sense functions also engage when
there is an impending collision
¢ page 137.
Which functions can be controlled?
You can switch the braking guard and the dis­
tance/approach warning on or off in the Infotain­
ment system ¢

A WARNING ,_
Lack of attention can cause collisions, other
accidents and serious personal injuries. The
braking guard is an assist system and cannot
prevent a collision by itself . The driver must
always intervene. The driver is always respon­
sible for braking at the correct time.
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al­
ways keep the safe and legal distance be­
tween your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
example when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
- Always remember that the radar sensor for
the braking guard works only within defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
promptly detected or may not be detected
at all.
- Reflective surfaces including crash barriers
or tunnel entrances may impair the function
of the radar sensor.
(D Tips
-You can cancel the braking with increasing
force that is initiated by the system by brak­
ing yourself, by accelerating noticeably or
by swerving.
- Keep in mind that braking guard can brake
unexpectedly. Always secure any cargo or
objects that you are transporting to reduce
t he risk of damage or injury.

Electronic Stabilization
Control (ESC)
Description
Elect ronic Stabilization Control (ESC) suppo rts
driver safety.
It red uces the risk of slipping and
improves dr iving stability. ESC detects crit ica l sit­
uations such as the veh icle oversteering and un­
dersteering or the wheels are sp inning. The vehi­
cle is stabilized by app lying the brakes or reduc ­
ing engine torque. As soon as the ESC is active ly
regulat ing, the
D.1 indicato r light blin ks in the in­
s trumen t clus ter.
The fo llow ing systems are integrated in the ESC :
Ant i-lock braking system (ABS)
ABS p revents the whee ls from locking whe n brak­
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis­
tance . It increases brak ing power when the driver
presses the brake pedal q uick ly in emergency sit­
uations . You must press and hold t he b rake pedal
until the dangerous sit uat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle dr iv ing ahead is too small. On
ve hicl es with act ivated and f unct io ni ng night vi ­
sion assist*, the brake assist system can respond mo re sensit ively if there is a warning .
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive w heels
be gin sp inning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler ­
ate and dr ive up h ills.
Electronic differential lock (EDL)
T he EDL applies the b rakes to a whee l t h at s tarts
sp inning and tra nsfe rs t he dr ive powe r to t he
o ther driving wheel or wheels (if the veh icle is
120
equipped with a ll w hee l drive*) . T h is f unction is
not avai lab le at higher speeds .
I n extreme cases , EDL automat ic al ly swi tches off
to keep t he b rake o n the br aked wheel from ove r­
heating. The ve hicle is still working correct ly. ED L
will switc h on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze th e vehicle by ch ang ing
t h e s teer ing torque.
I n veh icles with dynamic s teer ing*, ESC a lso
helps to stab ilize the s teeri ng in cr it ic al situ a­
tions.
Selective wheel torque control
Se lective wheel to rque control is used when d riv­
i ng on curves . The front whee l on the ins ide of
t h e curve or both whe els on the i nside of th e
cu rve are braked se lectively as needed. This al­
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "a utomat ic post -coll is io n braking system"
can help to reduce the risk of sl iding and of addi­
tiona l co llisions after an acc iden t. If the a irbag
c on tro l modu le dete cts a collision above a cer tain
vehicle speed, the veh icle is braked by t he ESC.
The veh icle does not brake automatically if:
- the drive r presses the accelerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle elect ri­
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. Th is is es pec ially i mpo rtan t
on s lippery or we t roads. If the system s be­
g in a cting to s tabili ze yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let the inc reased safety provided tempt

Intelligent Technology
Braking
New brake p ads
New b rake pads do no t achieve the ir full b raking
effect during the firs t 250 mi (400 km) . They
m ust be "broken in" first .
Wear
Brake pad wear depends largely o n the way the
ve hicl e is driven and on operat ing cond it ions.
This is especi ally true if you are d riving frequently
in the c ity and on c urves or with a sporty driving
style.
Operating noise
Noises may occur when bra king depend ing on the
speed, b raking force and outs ide cond it ions s uch
as temperature and humidity.
Effect of water and road salt
In ce rtain s ituations, for example after driving
through water, in heavy ra in, afte r ove rnight con­
densat ion or after washing your car, the b raking
effect can be red uce d by mo isture or ice on the
b rake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
At highe r speeds and with t he windshie ld wipers
turned on, the brake pads press against the bra ke
rotors for a short amount of time . This action,
which is not felt by the driver, happens at regular
intervals and ens ures a better reaction time for
the brakes in wet weathe r.
The braking effect can also be reduced if you are
driving on sa lted roads and you do not apply t he
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosi on
Leaving the vehicle parked for long periods of
time, low mi leage and avo iding heavy brak ing
can contribute to corrosion on the brake rotors
and to d irty brake pads.
If you usually avoid heavy b raking or if there is
corros ion present, occasional heavy braking at
122
high speeds is recommended to clean the brake
rotors and pads¢.&. .
Brake system malfunction
if you not ice that the b rake peda l t ravel has sud­
denly increased, then a br ake circuit in the du al­
c irc uit b rake system may have malfunctioned.
Drive to an authorized A udi dealer or authorized
A udi Se rvice Facility immediate ly to have the
problem corrected. On the way there, drive w ith
reduced speed and keep in m ind t hat you will
need a longer distance to stop and you will need
to press the brake peda l harder .
lo w b rake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
i s electronically monitored.
Brake booster
The brake boos ter amp lifies the pressure you ap ­
ply to the brake pedal. It only works when the en­
gine is running .
A WARNING
- Only app ly the brakes for the purpose o f
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users. This i ncreases the
r is k of an accident .
-
- Never let the ve hicle roll while the engine is
s topped because this i ncreases the ris k of an
accident .
- New brake pads do no t ach ieve the ir full
braking effect dur ing the first 250 m i
( 4 00 km). They m ust be "b roken in" fi rst.
However, you can compensa te fo r the
slightly reduced brak ing force by pressing
firm ly on the brake pedal. Avo id heavy brak ­
ing during the break-in period.
- Ce rtain weather and operating condi tions
such as d riving through water, dr iv ing in
heavy rain o r driv ing after washi ng your ve­
hicle can impai r the effectiveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and dr ums. Check

co

plying the brakes carefully several times
dries the brakes and removes ice bui ld-up.
- The effic iency of the brakes can also be im­
paired by driving for long stretches on roads
covered w ith salt without using the brakes.
You can remove salt deposits from the brake rotors and pads by ca ref ull y applyi ng
the brakes severa l t imes.
- If the front spo iler is damaged or you install
another spoiler, ma ke sure the front w heel
bra kes are vent ilated p roperly. O therwise,
t h e brake syste m could ove rheat, wh ic h re­
duces the ir effec tiveness.
- Failure of a bra ke circuit impai rs b raking
performan ce, which incre ases bra king dis­
tance . Avoid driving the vehicle and have it
towed it to the nearest authorized A udi
dealer or author ized Audi Service Facility .
- If the brake booste r is not working, you wi ll
have to press m uch ha rder on the bra ke
peda l to compensate for the lac k of the
booster.
(D Note
- Never let the brakes "rub" by pressing the
p edal light ly when bra king is not actually
necessa ry. This causes the brakes to over­
heat and increases bra king d istance and
causes wear.
- Befo re driving downh ill a long distance on a
steep h ill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to b rake additionally, brake in in­
te rvals and not cont inuous ly .
(0 Tips
- If the brake booster is not working, you
must p ress the brake pedal with much mor e
fo rc e th an norma l.
-If you re trofit your vehicle wi th a front spoil­
er, whee l covers o r similar items, ma ke sure
t h at t he ai r flow to the front whee ls is not
i nte rru pted. Ot he rw ise the brake sys tem

Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
E v ent Dat a Reco rd er
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 a irbag deployment or h itting a
road obstacle, data that will assist in understand­
i n g how a veh icle's sys tems performed . The EDR
is designed to record data re lated to veh icle dy­
namics and s afety systems for a sho rt pe riod of
t ime, typically 30 seconds or less. The EDR in th is
vehicle is designed to record s uch data as :
- How various systems in you r vehicle were oper­
at ing ;
- Whether or not the driver and passenger safety
belts we re buck led/fastened ;
- How far ( if at all) the drive r was depressing t he
acce le ra to r and/o r brake peda l; and,
- How fast the veh icle was trave ling .
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
veh icle only if a non-trivial crash situat ion occurs;
no data are recorded by the EDR under norma l
d riving conditions and no pe rsonal data (e .g.,
name, gende r, age , and crash location) are re­
corded . Howeve r, other pa rties , such as law en­
forcement, cou ld combine the EDR data w ith the
type of personally identifying data routine ly ac­
qu ired dur ing a crash invest igat ion.
To read data recorded by an EDR, specia l equip ­
ment is required, and access to the veh icle or the
EDR is needed. In addit ion to the vehicle manu ­
facturer, other parties, suc h as law enforcement,
that have the specia l equipment, can read the in-
126
format ion if they have a ccess to the vehicle or the
EDR .
Some sta te la ws rest ric t the retrieval or down­
l oad ing of data s tored by E D Rs ins talled in a veh i­
cle for the exp ress p urpose of retrieving data af ­
ter an accident or crash event without the own­ er 's consent.
Audi will not access the E DR and/or simi la r data
or give it to others -
- unless the ve hicle owne r (o r lessee if the vehi ­
cle has been le ased) 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 .
- 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 w itho ut identify ing the specific vehi­
cle or info rmation about the ident ity of its own­
er or lessee and only afte r the reco rded vehicle
data has been accessed .
Vehicle control modules
Your vehicle is also equ ipped w ith a number of
electronic cont rol modules for va rious vehicle
systems, such as engine management, em iss ion
con tro l, airbags, and safety be lts.
These elect ronic contro l modules record data
duri ng norma l vehicle operation t hat may be
needed by tra ined techn ic ians for d iagnost ic and
r epa ir purposes. The recording cap ab ili ty o f these
modules is lim ited to data (no sound is record ­
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, d irection, or braking, as well as re ­
straint system use and performance in the eve nt
of a crash . Stored data can also on ly be read and
downloaded w it h specia l equipment t hat is di­
r ectly connec ted to the vehicle.

Care and cleaning
-To reduce the risk of cuts, protect yourself
from sharp metal components when was h­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the braking effect
may be delayed due to mo isture on the
brake rotors or ice in the winter . This in­
creases the risk of an acc ident. The bra kes
must be d ried first w ith a few careful brake
applica tions.
0 Note
- If you wash the ve hicle in an automatic car
wash, you must fold the exterior m irrors in
to reduce the risk of damage. Power fo ld ing
ex ter ior mirro rs* m ust only be folded in and
out using the power folding function.
- To reduce the risk of paint damage, do not
wash the vehicle i n dire ct sunlig ht.
- T o reduce t he risk of damage to the surface,
do not use i nsec t remov ing sponges, ki tchen
s ponges or similar items. - Matte finish painted vehicle components:
-To reduce the r isk of damage to the sur-
face, do not use polis hing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved. @ For the sake of the environment
Only wash t he ve hicle in facilities spec ially de­
signed for that pu rpose. This will reduce the
r isk of dirty wate r contaminated with o il from
ente ring the sewe r system.

Replacing wheels
Before changing a wheel
Observe the following precautions for your own
and your passenger's safety when changing a
wheel .
.,. After you experience a tire failure, pull the car
well away from moving traffic and try to reach
level ground before you stop¢,&. .
.,. All passengers should
leave the car and move
to a safe location (for instance, beh ind the
guardrail)¢ ,&..

.,. If you are towing a trailer, unhitch the trailer
from your vehicle.
.,. Take the
jack and the spare tire* out of the lug­
gage compartment c:> page 236.
A WARNING
You or your passengers could be inju red wh ile
changing a wheel if you do not follow these
safety precautions:
- If you have a flat tire, move a safe distance
off the road. Turn off the engine, turn the
emergency flashers on and use other warn ­
ing devices to alert other motorists .
- Make sure that passengers wait in a safe
place away from the vehicle and well away
from the road and traffic.
- T o help prevent the vehicle from moving
sudden ly and possibly slipping off the jack,
always fully set the parking brake and block
the wheel diagonally opposite the wheel be­ ing changed. When one front wheel is lifted
off the ground, plac ing the Automatic
Transmission in P (Park) will
not prevent the
vehicle from mov ing.
