Assist Electronic speed limiter*
Applies to veh icles: with electronic speed limiter
Your vehicle may be factory equipped with ti res
that are rated for a maximum speed of 130 mph
(210 km/h) . T his is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tir e speed rat ing . For more information
~page 221.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢4 will illuminate . If this occurs,
contact the nearest a utho rized Audi dealer for as­
sistance .
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions . Never drive your
vehicle faster than the maximum speed rating of the tires installed.
Speed warning system
Introduction
The speed warning system helps you to stay un­
der a specified maximum speed.
-
The speed warning system warns you if you are
exceeding the maximum speed that you have set .
You will hear a warning tone when your speed ex­
ceeds the stored value by approximately 3 mph
(3 km/h) . Th e. (USA models)/. (Canada
models) indicator light and the message
Speed
limit exceeded!
appear in the instrument cluster
disp lay at the same time . The ./. indicator
light turns off when the speed decreases below
the stored maximum speed.
Setting a thresho ld is recommended if you would
like to be reminded when you re ach a certain
maximum speed. Situations where you may want
to do so include driving in a country with a gener-
94
al speed limit or if there is a specified maximum
speed for winter tires.
(D Tips
Regardless of the speed warning system, you
should always monitor your speed using the
speedometer and make sure you are following
the legal speed limit .
Setting the threshold
You can set, change and delete the threshold in
the MMI.
.. Select: the I MENU I button >Car> Systems*
contro l button > Driver assistance > Speed
warning.
You can set any threshold between 20 mph
(30 km/h) and 150 mph (240 km/h) . Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
· Description
Applies to vehicles: with cruise control system
The cruise control system makes it poss ible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modify ing engine
power or through an act ive brake intervention.
A WARNING
- Always pay attention to the traffic around
you when the cruise control is in operation.
You are a lways responsible for your speed
and the distance between your vehicle and
other vehicles.
- For reasons of safety, cruise contro l should
not be used in the city, in stop-and-go traf­
fic, on winding roads and when road condi­ tions are poor (such as ice, fog, gravel,
heavy rain and hydroplaning) -you could
have an accident .
- Switch the cruise control off temporarily
when driv ing in turning lanes, highway exits
or in construction zones .

Intelligent Technology
Intelligent 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;
- 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 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. 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 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 veh icle or the
EDR.
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-
122
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) ag rees; 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 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 contro l modules for var ious 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
r epair pu rposes. 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 brak ing, 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
r ect ly 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 se rv ic es that are pro ­
v id ed by a third party wireless telecommuni­
cations provider. For details regarding how in­
formation obtained through Audi connect is

Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Contro l (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti ­
cal s ituations such as the vehicle oversteering
and understeering or the wheels a re spinning.
The vehicle is stabilized by applying the brakes or
reducing engine torque. Once the ESC is activat­
ed, the indicator light
DJ blinks in the instru­
ment cluster.
The fol low ing systems a re integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
i ng. The vehicle can still be steered even during
hard braking . Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal ind icates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the driver
presses the brake pedal quickly in emergency s it­
uations. You must press and hold the brake pedal
unti l the dangerous sit uation is ove r. In vehicles
with adaptive cruise control *, the brake assist
system is more sensit ive if the distance detected
to the vehicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up inclines.
Intelligent Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other drive wheel
or whee ls if the vehicle is equipped with all wheel
drive*). This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over ­
heating. The vehicle is still working correct ly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
Selective wheel torque control
Selective wheel torque control is used when dr iv­
i ng on curves. The front wheel on the inside of
the curve o r both wheels on the inside of the
curve are braked selectively as needed . This al­
lows more precise driving in curves .
Automatic post-collision braking system
The "Automat ic post -collision braking system"
can help to reduce the ris k of sliding and of other
collisions after an accident. If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electr i­
cal system are not funct ion ing .
A WARNING
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pery or wet roads .
If the systems begin act­
ing to stabilize your vehicle, you should im-
mediately a lter your speed to match the ..,.

Intelligent Technology
& 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 slight·
ly reduced braking force by pressing firmly
on the brake pedal. Avoid heavy braking dur·
ing the break-in period.
- Alway 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·
hide 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·
126
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 ped·
al 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 nee·
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 then normal.
- If you retrofit your vehicle with a front spoil·
er, wheel covers or similar items, make sure
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.
T he 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.
