This message appea rs if the electronic stabiliza ­
tion control (ESC) is taking action to stabilize the
veh icle. The adaptive cruise control turns off. A
chime sounds as a reminder.
Speed too low
This message appears if the current speed is too
low
to set or to maintain the des ired speed .
The speed being saved must be at least 20 mph (30 km/h) . The cruise contro l is turned off for
speeds lower than 12 mph (20 km/h). The adap­
tive cruise control remains turned on for speeds
above 95 mph (150 km/h) (override). It w ill sta­
bilize again at 95 mph (150 km/h) when the driv­
er takes his foot off of the gas pedal.

Driving safety
proper deployment of the airbag. Small ob­
jects can be thrown through the vehicle if
the airbag deploys and injure you or your passengers.
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat or
any other object.
Make sure that all pedals move freely without in­
terference and that nothing prevents them from returning to their original pos itions .
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners .
If a brake circuit fails, increased brake pedal trav­
el is required to bring the vehicle to a full stop.
A WARNING
Pedals that cannot move freely can cause loss
of vehicle control and increase the r isk of seri­
ous inJury.
- Never place any objects in the driver's foot­
well. An object could get into the pedal area
and interfere with peda l function. In case of
sudden braking or an accident, you would
not be able to brake or accelerate!
- Always make sure that noth ing can fall or
move into the dr iver's footwell.
Floor mats on the driver side
Always use floor mats that can be securely at­
tached to the floor mat fasteners and do not in­
terfere with the free movement of the pedals .
.,. Make sure that the floor mats are properly se­
cured and cannot move and interfere w ith the
pedals ~
&-
Use only floor mats that leave the pedal area un­
obstructed and that are f irm ly secured so that
they cannot slip out of pos ition. You can obtain
suitable floor mats from your authorized Audi
dealer.
116
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached
to these fasteners. Properly securing the floor
mats will prevent them from sliding into posi­
tions that could interfere with the pedals or im­
pair safe operation of your vehicle in other ways.
A WARNING
Pedals that cannot move free ly can result in a
loss of vehicle control and increase the risk of
serious personal injury.
-Always make sure that floor mats are prop­ erly secured.
- Never place or install floor mats or other
floor coverings in the vehicle that cannot be
properly secured in place to prevent them
from slipping and interfering with the ped­
als or the ability to control the vehicle .
- Never place or install floor mats or other
floor coverings on top of already installed
floor mats . Additional floor mats and other
coverings will reduce the size of the peda l
area and interfere with the pedals .
- Always properly reinstall and secure floor
mats that have been taken out for cleaning.
-Always make sure that objects cannot fall
into the driver footwell while the vehicle is mov ing. Objects can become trapped under
the brake pedal and accele rator pedal caus­
ing a loss of vehicle control.

Smart Technology
Smart Technology 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;
- Whe ther 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 provide a better understand­
ing of the circumstances in which crashes and in­
juries occur. NOT E: 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 part ies, such as law en­
forcement, could combine the EDR data with the
type of personally identify ing data routinely ac­
qui red during a crash investigation.
To read data recorded by an EDR, special equip­
ment is requ ired, and access to the vehicle or the
E DR 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 E DR.
Some state laws restrict the retrieval or down­
loading of data stored by EDRs installed in a vehi­
cle for the express purpose of retrieving data af-
168
ter an accident or crash event without the own ­
er's consent.
Audi will not access the EDR and/or similar data
o r g ive it to others -
- unless the veh icle owner (or lessee if the veh i­
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 spec ific vehi­
cle or information about the ident ity 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 var ious vehicle
systems, such as engine management, emission
control, airbags, and safety belts .
These electronic control modules record data dur ing norma l vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capabil ity of these
modules is lim ited to data (no sound is recorded).
Only a small amount of data is actua lly recorded
over a very limited period of time, or stored when
a system fau lt is detected by a contro l modu le.
Some of the data stored may relate to vehicle
speed, direction, or braking, as well as restraint
system use and performance in the event of a crash. Stored data can also only be read and
down loaded w ith specia l equipment that is di­
rectly connected to the vehicle.
(D Tips
Your vehicle may be equipped with Audi con­
nect . Your use of certain Audi connect fea­
tures requires wireless serv ices that are p ro­
v ided by a third party wireless telecommuni­
cations provider . For details regarding how in­

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of skid­
ding and loss of vehicle control. It works only
when the engine is running. ESC detects certain
d ifficu lt driving situations, including when the ve­
hicle is beginn ing to spin (yaw) out of control and
helps you to get the vehicle back under control by
selectively braking the whee ls, and/or reducing
engine power and prov iding steer ing ass istance
to help hold the vehicle on the driver's intended
course. The indicator light
Bl in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations.
It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
ditions you may come up against. For example, ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of frict ion of the road surface . Whe n
there is a section of dry road that is suddenly cov­
ered with water, slush or snow, ESC cannot per­
form the same way it wou ld on the dry surface. If
the vehicle hydroplanes (rides on a cushion of wa­
ter instead of the road surface), ESC will not be
ab le to he lp you steer the vehicle because contact
with the pavement has been interrupted and the
vehicle cannot be braked or steered . During fast
cornering, particularly on winding roads, ESC
cannot always deal as effectively with difficult
driving situations than at lower speeds. Whe n
tow ing a trailer, ESC is not able to help you regain
con trol as it wou ld if you were no t towing a trail­
er .
A lways adjust your speed and dr iving sty le to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limits, increase the
Smart Technology
available traction, or keep a vehicle on the road i f
road departure is a result of driver inattention.
Instead, ESC improves the possibility of keeping
the vehicle under control and on the road dur ing
extreme maneuvers by using the driver's steering
inputs to help keep the vehicle go ing in the in ­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can prov ide any assistance, you may not expe ri­
ence the benefits of ESC.
ESC is switched on all the time . In certain situa­
t ions when you need less traction, you can switch
off ASR by pressing the button
[ru ~ page 170,
fig. 152 or ~page 170, fig . 153. Be sure to
switch ASR on again when you no longer need
less traction.
T he following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when braking. The vehicle can still be steered even dur­
i ng hard braki ng. Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is he lp­
ing you to brake the vehicle.
Brake assist system
The brake ass ist system can decrease braking dis­
tance . It increases braking power when the driver
presses the brake peda l quickly in emergency sit­
u at ions. You must press and hold the brake pedal
until t he situat ion is over. In vehicles with adap­
tive cruise control*, the brake assist system is
more sensitive if the distance detected to the ve­
hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
T he EDL brakes whee ls that are spinning and
transfers the drive power to the other wheels.
T his function is available up to about 60 mph
(100 km/h).
169

Smart Technology
In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati­
cally when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
I n vehicles with dynamic steering*, ESC also
he lps to stabilize the steering in critical situa­
tions .
Selective wheel torque control
Select ive wheel torque control is used when driv­
ing on c urves . The front wheel on the inside of
the curve or both whee ls on the inside of the
curve are braked selectively as needed. This al­
lows more precise driving in curves . Th e applica­
b le system may not activate when driving in wet
or snowy conditions .
A WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
c ially important on slippery or wet roads. If
the systems beg in acting to stabilize your
vehicle, you should immediately change
your speed to match the road and traffic
Switching on/off
conditions . Do not let the increased safety
provided by these systems tempt you to
take risks. Doing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle increases when dr iving
too fast, especially through curves and on
slippery or wet roads, and when driv ing too
close to vehicles up ahead. The ESC and its
integ rated systems cannot always prevent
collisio ns -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that cannot always help to reduce
the risk of loss of vehicle control.
@ Tips
-ABS and ASR only work correctly when all
four wheels are equ ipped w ith identical
t ires. Different tire s izes can lead to a reduc­
t ion in engine power.
- You may hear noises when the systems de­ scribed are working.
ESC turns on automatically when you start the engine .

The ESC is designed to function in levels. Depend­
ing on the level that is selected, the stabilization
function of the ESC is limited or switched off. The

Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking e ffect, they
have to be "broken in" first¢.&. . The break -in pe ­
riod can be considerably longe r for vehicles with
ceramic brake rotors*. You can compensate for
th is slightly reduced braking power by pushing
harder on the brake pedal. Avoid heavy braking
loads during the b reak-in period.
Op era ting condition s and dri ving h abit s
The brakes on today's automobiles are still sub­
j ect to wear, depending largely on operating con­
dit ions and driving habits ¢.&, . On vehicles that
are either dr iven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by yo ur autho rized Aud i dealer more of­
ten than specified in the
Warranty & Mainte·
nan ce bookl et.
Fail ure to have you r brake pads
i nspected c an resu lt in red uced b rake pe rform ­
ance.
On steep slopes, you shou ld use the braking ef­
fect of the engine. This way, you prevent unnec ­
essary wear on the bra ke system. If yo u must use
you r brakes, do not hold the brakes down contin ­
u ously. Pump the brakes at intervals .
Operating noise
Noises may occur when brakin g depending on the
speed, braking force and ou ts ide cond itions su ch
as tempera ture and hum idity.
Due to the nature of the materials used in ceram­
i c bra ke roto rs*, noises may become mo re appa­
r ent at low speeds.
Effect of water and road salt
In certa in situations, for examp le after driv ing
through water, in heavy rain, after overnight con­
densation or after washing your car , the braking
effect can be redu ced by moistu re or ice on the
1111>

brake rotors and brake pads. The brakes must be
dried first with a few carefu l brake applications .
At h igher speeds and with the w indshield w ipers
turned on, the brake pads press against the brake rotors for a sho rt amount of time. This occurs at
regular intervals without the driver noticing and
prov ides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likew ise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢,&. .
Due to their surface characteristics, ceram ic
brake rotors* absorb moisture in such conditions.
This can cause a temporary reduction in braking
force compared to dry brakes . You can compen ­
sate for this by press ing the brake pedal harder .
Corrosion
There may be a tendency for dirt to bui ld up on
the brake pads and corrosion to form on the discs
if the car is not driven regularly or only for short
trips with little use of the brakes .
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by brak ing firmly a
few t imes from a moderately high speed¢& .
Fa ul ts i n the brake sys te m
If you should notice a sudden increase in brake
pedal travel, then one of the two brake circuits
may have failed¢&.
Low brak e flu id l eve l
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid leve l is
monitored e lectronically.
Brake boo ste r
The brake booster increases the pressure that you
genera te with the brake pedal.
It works only M

Brake lining wear statu s
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
thro ugh the openings in the wheel. If necessary,
the wheel may be removed for this inspection
¢ page 218, Replacing wheels .
A WARNING ...__
-New brake pads don't have the best stop­
ping power and must be "broken-in" during
the initial 250 miles (400 kilometers) . The
break-in per iod can be cons iderably longer
for vehi cles w ith ceramic b rake rotors*. You
can compensate for this by p ress ing the
b rake peda l more fi rmly. This a lso applies
later when new pads are installed.
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at risk -you may
cause an accident!
-
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride the
brakes or hold the pedal down too long or
too often . This could cause the brakes to get
hot and dimin ish braking effic iency .
- Do not "ride the brakes" by rest ing your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p ing distance.
- Under certain cl imatic and operat ing condi­
tions such as passing t hrough water, dr iv ing
in heavy rain or after washing the veh icle,
the effect iveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fu lly apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on salt-covered roads without using your
brakes can a lso affect braking efficiency.
Clean off accumulated salt coating from brake discs and pads with a few careful
brake applications.

-If y ou dama ge the front spo iler, or if you in ­
sta ll a di fferent spoile r, be sure the air flow
to the front brakes is not obstructed . Other ­
wise the brake system co uld overheat reduc­
