as a pulsing mot ion of the brake pedal, ac-
companied by some noises. I n order for ABS
to be able to operate optimally in th is range,
you must keep the brake pedal depressed -
never "pump the brakes" . You should not ex-
pect that braking distances w ill be
shortened
under all circumstances with ABS. Braking dis-
tance may even be slightly
longer ,
for exam-
ple on gravel or wi t h fresh snow on a slippery
surface .
If a sign ificant
speed differential
between the
drive w heels on one axle is determined (for
examp le, on a surface that is sli ppery
on one
side),
t he EDS brakes the spinn ing whee l and
transfers power to the other drive whee ls.
This is done up to a speed of about 60 mph
(100 km/h) . Noises from the brake system
signal that whee l spin is being controlled.
If one wheel spins when st arting from a com-
plete stop because of a different grip (for ex-
ample , one wheel on ice), keep your foot
hard
on the accelerator until the veh icle starts to
move.
If the wheels spin , ASR wi ll automatically re-
duce engine torque and match power to road
surface condit ions .
Switching on Sport mode
I n specific drivi ng situa t ions (e.g. Launch Con-
trol), you switch ASR and ESC to Sport mode
by pressing the
[!I
button once. The indicator
light
11
illuminates and ESP sport -Warning!
Restricted stability appears . "Slip" is matched
to the speed. You should do this only if your
driving skill and traffic condit ions permit .
Switching ASR/ ESC off
In certain sit uat ions (e.g. in deep snow, on a
loose surface, or when rocking the vehicle
free), switch ASR and ESC off by pressing the
[ill
button for more than 3 seconds. The ind ica-
tor light
II
illuminates and ESP swit ched off -
Warning! Restricted stability appears. You
should do th is only if your driving skill and
traffic condit ions permit .

Switching ASR/ ESC on
Activate ASR/ESC by pressing the
[!I
butt on
again. The message ESP on appears in the dis-
play briefly.
Brake overheating
So that the disc brake on a braked wheel does
not overheat, the EDS switche s off aut omat i-
cally if there is un usually severe loa ding at
th is wheel. The vehicle is st ill dr ivable and has
the same properties as a vehicle without EDS .
As soon as the brake has cooled down, EDS
swit ches on again automatically .

WARNING
- Even ESC, ABS, EDS and ASR cannot over-
come the laws of physics. You should
keep t his in m ind in particular on an icy
or wet road. If the systems intervene,
you shou ld adj ust your speed immediate-
ly to road and traff ic conditions . Do not
be tempted by the increased safety pro-
vided to take risks - you risk having an
accident.
- Please keep in mind that the risk of an
accident is increased by driving too fast,
parti cularly in corners and on icy or wet
roads, and by drivi ng too close to t he ve-
hicle ahead. Even ESC, ABS, EDS and ASR
cannot eliminate the increased risk of
having an accident.
-Apply t he throttle caref ully when accel-
erating on a consistently sli ppery sur-
face, e.g. on ice and snow. The drive
wheels can spin in spite of the EDS and
thereby affect vehicle stability - you risk
having an accident .
- Please note that when ASR or ESC/ASR is
deactivated , the drive wheels can spin on
icy and slippery roads and the veh icle can
break away - the re is a risk of skidd ing!

Tips
- In the event of a defect in the rear spoil-
er system or in Audi magnet ic ride, it can
happen that ASR and ASR/ESC cannot be
