Electronic Stabilization
Control (ESC)
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and
improves driving stability. ESC detects critical sit-
uations such as the vehicle oversteering and un-
dersteering or the wheels are spinning. The
brakes are applied or the motor torque is reduced
in order to stabilize the vehicle. When the ESC
engages, the B indicator light flashes in the in-
strument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak-
ing. 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 indicates that the system is acting to
stabilize the vehicle.
Brake assist
The brake assist system can decrease braking dis-
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit-
uations. You must press and hold the brake pedal
until the dangerous situation is over.
Anti-Slip Regulation (ASR)
ASR reduces drive power when the wheels begin
spinning and adapts the power to the road condi-
tions. This will increase the driving stability.
Electronic Differential Lock (EDL)
The EDL applies the brakes to wheels that are
slipping and transfers the drive power to the oth-
er wheels. 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 functioning correctly.
EDL will switch on again automatically when con-
ditions have returned to normal.
104
Power steering
The ESC can also support vehicle stability
through steering.
Selective wheel torque control
Selective wheel torque control is used when driv-
ing on curves. Braking is targeted toward the
wheels on the inside of the curve as needed. This
allows more precise driving in curves.
Automatic post-collision braking system
The automatic post-collision braking system can
help to reduce the risk of sliding and of addition-
al collisions after an accident. If the airbag con-
trol module detects a collision above a certain ve-
hicle speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if one of
the following occurs:
— The driver presses the accelerator pedal
—The braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system
— The ESC, the brake system, or the vehicle elec-
trical system is not functioning

Z\ WARNING
— The ESC and its integrated systems cannot
overcome the limits imposed by natural
physical laws. This is especially important on
slippery or wet roads. If the systems begin
acting to stabilize your vehicle, you should
immediately alter your speed to match the
road and traffic conditions. Do not let the in-
creased safety provided tempt you into tak-
ing risks. This could increase your risk of a
collision.
— Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv-
ing too close to objects ahead. There is still
a risk of accidents because the ESC and its
integrated systems cannot always prevent
collisions.
— Accelerate carefully when driving on
smooth, slippery surfaces such as ice and
snow. The drive wheels can spin even when
these control systems are installed and this

Image recording
Surrounding area monitoring
Applies to: vehicles with surrounding area monitoring
Some vehicle functions require the vehicle’s path
to be detected and evaluated. This is done by
cameras installed permanently on the vehicle
that detect objects in the vehicle's surroundings
(such as obstacles or guard rails). The live images
from the cameras are transmitted to the applica-
ble control module.
The camera images are transmitted to the appli-
cable control module and stored for processing.
The control module analyzes the current camera
image using image evaluation software. This im-
age evaluation software detects anonymized
technical measurements, such as distances to ob-
jects. The control module evaluates these techni-
cal measurements and makes it possible for the
assist systems to control the vehicle, if necessary.

Fig. 200 Driver's side footwell: connection port for the On
Board Diagnostic System (OBD)
Your vehicle is equipped with electronic control
modules for various vehicle systems such as the
256

airbags. These vehicle control modules store data
while driving normally that is required by an au-
thorized Audi dealer or authorized Audi Service
Facility for diagnosis and repair purposes. Only
certain types of data are recorded for a very short
period of time if a control module has detected a
system event. No noises, conversations, or im-
ages will be recorded in the vehicle.
The data may include information such as the ve-
hicle speed, the direction of travel, and informa-
tion about the brake system, or also the behavior
of the restraint system in the event of an acci-
dent. The stored data can be exported and down-
loaded with special devices, which must be con-
nected directly to the vehicle.
On Board Diagnostic System (OBD)
There is a diagnostic connector socket in the driv-
er's side footwell to read out the various control
modules and the event data recorder. Data re-
garding the function and condition of the elec-
tronic control modules is stored in the event
memory. Only have an authorized Audi dealer or
authorized Audi Service Facility read out and de-
lete the event memory.

ZA\ WARNING
— Incorrect use of the connection port for the
On Board Diagnostic System can cause mal-
functions, which can then result in accidents
and serious injuries.
— Only allow an authorized Audi dealer or au-
thorized Audi Service Facility to read out the
motor data.

Accessories and technical changes

Usually maintenance and repair work requires
special tools, measuring devices, and other
equipment that is available to trained vehicle
technicians in order to help ensure that your vehi-
cle and all of its systems operate correctly, relia-
bly, and safely. Performing work on the vehicle
incorrectly can impair the operation and reliabili-
ty of your vehicle and may void one or more of
your vehicle's warranties.
Technical Modifications
Interference with electronic components, their
software, the wiring, and data transfer may cause
malfunctions. Because of the way electronic com-
ponents are interconnected, such malfunctions
can also impair systems that are not directly in-
volved. This means that you risk both a substan-
tial reduction in the operational safety of your ve-
hicle and increased wear of vehicle components.
Some convenience functions, such as the conven-
ience turn signal function, individual door open-
ing function, and displays, can be reprogrammed
using special workshop equipment. If functions
are reprogrammed, the information and descrip-
tions about these functions in this Owner's Man-
ual may no longer apply to the changed func-
tions. Audi recommends that an authorized Audi
dealer or authorized Audi Service Facility perform
and verify any reprogramming procedures.


— Never perform any work in the motor com-
partment unless you know exactly how to
carry out the job and have the correct tech-
nical information and the correct tools.
— If you are uncertain about what to do, have
the work performed by an authorized Audi
dealer, an authorized Audi Service Facility,
or another qualified workshop. Serious per-
sonal injury may result from improperly per-
formed work.


Z\ WARNING
Maintenance work, repairs, or technical modi-
fications to the vehicle (such as installing ad-
ditional equipment) that is not performed
correctly can cause serious injuries and in-
crease the risk of an accident.


ZA\ WARNING
The motor compartment in any motor vehicle
is a potentially dangerous area and can cause
serious personal injury.
— Always use extreme caution when doing any
work in the motor compartment. Always fol-
low commonly accepted safety practices and
use common sense. Never risk personal in-
jury.

@) Note
— Maintenance work, repairs, or technical
modifications to the vehicle (such as instal-
ling additional equipment) that is not per-
formed correctly can cause vehicle damage.
— If emergency repairs must be performed,
take your vehicle to an authorized Audi deal-
er or authorized Audi Service Facility as soon
as possible.
— Audi is not liable for damage to the vehicle
resulting from failure to comply with these
guidelines.
@) For the sake of the environment
— Regular maintenance can help protect the
environment.
— Technical modifications to the vehicle can
have a negative impact on fuel consumption
and vehicle emissions.
@) For the sake of the environment
Certain components in your vehicle such as
undeployed airbag modules, pretensioners
and remote control batteries may contain Per-
chlorate Material - special handling may ap-
ply, See www.dtsc.ca.gov/hazardouswaste/
perchlorate. When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are scrap-
ped, all applicable laws and regulations must
be observed. Your authorized Audi dealer is
familiar with these requirements and we rec-
ommend that you have your dealer perform
this service for you.

Accessories and technical changes

@) Tips
Because of your vehicle's aluminum body de-
sign, all service and repair procedures affect-
ing the body should be performed by an au-
thorized Audi dealer or authorized Audi Serv-
ice Facility, who will perform the work accord-
ing to Audi factory specifications. Only Audi
Genuine Parts are used when Audi experts
perform repair or service procedures. Failure
to use Audi Genuine Parts or Audi Genuine Ac-
cessories or performing repairs incorrectly
may result in severe vehicle damage, such as
corrosion.
Accessories and parts
Consult with an authorized Audi dealer or author-
ized Audi Service Facility before purchasing ac-
cessories or replacement parts. Audi recom-
mends having your vehicle serviced by an author-
ized Audi dealer or authorized Audi Service Facili-
ty and using Audi Genuine Parts and Audi Genu-
ine Accessories.
Audi does not endorse the use of products and
accessories that it has not evaluated, even if the
product is approved by a certified testing agency
or government agency.

ZA\ WARNING
— Installing unapproved accessories or incor-
rect replacement parts can cause vehicle
damage and can increase the risk of an acci-
dent.
— Never attach accessories, such as telephone
holders or cup holders, to the airbag covers
or within the airbag deployment zone, be-
cause this increases the risk of injury if the
airbag deploys.
— On vehicles that have factory-installed li-
cense plate brackets on the front of the ve-
hicle, the brackets may only be replaced
with ones that are the same size and made
of the same material. Do not install any li-
cense plate brackets on the front of vehicles
that do not have factory-installed brackets.
Otherwise, the function of the system could
be impaired.

@) Note
A correctly-installed exterior antenna is re-
quired for operating radio equipment in the
vehicle. Otherwise, the increased electromag-
netic waves can cause malfunctions in the ve-
hicle. Observe the regulations in the country
where the vehicle is being operated and the
instructions from the radio equipment manu-
facturer.
Reporting Safety Defects
Applicable to U.S.A.
If you believe that your vehicle
has a defect which could cause a
