turn on and the message appears, the ABS or
e lectronic differential lock is ma lfunctioning.
This a lso causes the ESC to malfunction . The
brakes st ill function with the ir normal power,
but ABS is not active.
Drive to your authorized Audi dea ler or quali ­
fied workshop immediately to have the mal­
function corrected.
A WARNING
-
If the ~ (USA models)/ . (Canada
models) brake system ind icator light turns
on together with the ABS and ESC ind ica­
tor lights, the ABS/ESC regulating function
may have fai led. Functions that stabilize
the vehicle a re no longer ava ilab le. This
could cause the vehicle to swerve and in­
crease the risk of sliding. Drive carefully to
the nearest a uthorized Audi dea ler or oth­
er qualified workshop and have the mat-
function corrected.

The fl (USA models) tE,I (Canada models) in­
dicator light monitors the safety systems (e.g.
a ir bags, pretensioners) and illuminates for a
few seconds each time you switch the ignition
on .
If the
fl (USA models) tE,I (Canada models)
indicator light does not go out, or if it illumi- nates while you are driving, or if it starts to
blink,
then there is a malfunction somewhere
in the system. If the light does not illuminate
when you switch the ign ition on, this also
means there is a malfunction.
A WARNING '"--
If you have a malfunction in the safety sys-
tems, contact your authorized Audi dealer
imme diately. Otherwise the safety sys­
tems may not work properly in an acc i­
dent.

.&_ WARNING
-
- If the~ (USA models) l[!J (Canada
mode ls) warning light does not go out,
or if it comes on while driving, the ABS
system is not working properly. The vehi­
cle can then be stopped only with the
standard brakes (without ABS). You will
not have the protection ABS provides.
Contact your authorized Aud i dealer as
soon as poss ible.
- If the
1111 (USA models)/. (Canada
mode ls) brake system indicator light
turns on together with the ABS and ESC
indicator lights, the ABS/ ESC regu lating
function may have failed. Functions that
stabilize the vehicle are no longer availa­
ble. This could cause the vehicle to
swerve and increase the risk of sliding.
Drive caref ully to the nearest authorized
Audi dealer or other qualified workshop
and have the malfunction corrected.
::\ii(®) Electromechanical parking brake
The warning/indicator light monitors the
electromechanical parking brake.
With the parking brake applied and the igni­
tion turned on, the. (USA models)/ . (Can­
ada models) warn ing/ indicator light illumi­
nates. After the ignition has been turned off,
the warn ing/ indicato r light continues to illu­
minate for about 30 seconds.
If the parking
brake is applied with the ignition turned off,

about 30 seconds.
T he wa rning/i ndicator lig ht will go out when
the parking brake is released.
If the warning/indicator light flashes continu­
ously
after applying the pa rking brake, brak­
ing force is not sufficient to prevent the veh i­
cle from rolling unintentionally . Please note
the following:
- If the slope of the ground is too steep to
pa rk the vehicle, the additional drive mes­
sage appears Caution : Vehicle parked too
steep.
- In the event of a pa rking brake malfunction,
the yellow
IIJ symbo l appears in the instru­
ment cluster display and the driver message

Have the ma lfunction repa ired as soon as
possible by an authorized Audi dealer or any
other qualified workshop.
BRAKE/((D) Brake system
The warning/indicator light flashes if brake
fluid level is low, if there is an ABS system
malfunction or a parking brake malfunction.
The 1111 (USA models)/ . (Canada models)
li ght illuminates when the ignition is turned
on. It goes out after the engine has been
started . This indicates that the brake warning
l ight is functioning properly.
If the brake warning light does not light up
when the engine is cranking, there may be a
malfunction in the electrical system. In this
case, contact an authorized Audi dealer. ..,.

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
ping and improves driving stability. ESC de­
tects critical s ituations such as the vehicle
Intelligent technology 197
oversteering and understeering or the whee ls
spinning . The vehicle is stabilized by applying
the brakes or reducing eng ine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL), dy­
namic steering*, hill descent assist and selec­
tive wheel torque control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking . The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations . You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
distance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels beg in to sp in and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hill s.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the othe r whee ls .
T his function is available up to about 78 mph
(125 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomatically when conditions have returned to
normal.
