Electronic Stabilization
Control (ESC)
Description
Elect ronic Stabilization Control (ESC) suppo rts
driver safety.
It red uces the risk of slipping and
improves dr iving stability. ESC detects crit ica l sit
uations such as the veh icle oversteering and un
dersteering or the wheels are sp inning. The vehi
cle is stabilized by app lying the brakes or reduc
ing engine torque. As soon as the ESC is active ly
regulat ing, the
D.1 indicato r light blin ks in the in
s trumen t clus ter.
The fo llow ing systems are integrated in the ESC :
Ant i-lock braking system (ABS)
ABS p revents the whee ls from locking whe n brak
ing. The vehicle can sti ll be steered even during
hard brak ing. Apply steady press ure to the brake
pedal. Do not pump the pedal. A puls ing in t he
b rake pedal indicates that the system is acting to
s tabilize the vehicle .
Br ake assist system
The brake assist system can decrease brak ing dis
tance . It increases brak ing power when the driver
presses the brake pedal q uick ly in emergency sit
uations . You must press and hold t he b rake pedal
until the dangerous sit uat io n is over . In veh icles
with adapt ive c ruise control*, the bra ke as sist
sy stem is more sensitive if t he di sta nce detec ted
t o the vehicle dr iv ing ahead is too small. On
ve hicl es with act ivated and f unct io ni ng night vi
sion assist*, the brake assist system can respond mo re sensit ively if there is a warning .
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive w heels
be gin sp inning an d adapts the force to the road
conditions. This makes it easie r to sta rt, acceler
ate and dr ive up h ills.
Electronic differential lock (EDL)
E DL a ppl ies the bra kes to a wheel tha t st art s
sp inning and tra nsfe rs t he dr ive powe r to t he
120
other driving whee ls. This func tion is no t ava ila
ble at hig her speeds.
I n extreme cases , EDL automat ic al ly swi tches off
to keep t he b rake o n the br aked wheel from ove r
heating. The ve hicle is still working correct ly. ED L
will switc h on again automatically when condi
tions have returned to normal.
Steering recommendation
The ESC he lps to s tabili ze th e vehicle by ch ang ing
t h e s teer ing torque.
I n veh icles with dynamic s teer ing*, ESC a lso
helps to stab ilize the s teeri ng in cr it ic al situ a
tions.
Selective wheel torque control
Se lective wheel to rque control is used when d riv
i ng on curves . The front whee l on the ins ide of
t h e curve or both whe els on the i nside of th e
cu rve are braked se lectively as needed. This al
l ows mo re pre cise driving in curves .
Automatic post -collision braking system
The "a utomat ic post -coll is io n braking system"
can help to reduce the risk of sl iding and of addi
tiona l co llisions after an acc iden t. If the a irbag
c on tro l modu le dete cts a collision above a cer tain
vehicle speed, the veh icle is braked by t he ESC.
The veh icle does not brake automatically if:
- the drive r presses the accelerator pedal, or
- the bra king force generate d by the pressed
brake pedal is greater than the b raking force
that would be in itiated by the system, or
- the ESC, the bra ke system or the vehicle elect ri
cal system are not functioning.
A WARNING
- The ESC and its integ rated systems can not
overcome the lim its imposed by natura l
p hys ica l laws. Th is is es pec ially i mpo rtan t
on s lippery or we t roads. If the system s be
g in a cting to s tabili ze yo ur vehicle, you
should immedi ately alte r your speed to
match the road and tra ffi c conditions. Do
not let the inc reased safety provided tempt

you into taking risks. This could increase
your risk of a collision.
- Please note the risk of a co llision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv
ing too close to objects ahead. The ESC and
its integrated systems cannot always pre
vent collisions -there is still a r isk of acci
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin

even when these control systems are instal
led and this can affect driving stability and
increase the risk of a collision.
(D Tips
- ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire s izes can lead to a reduc
tion in engine power.
- You may hear noises when the systems de
scribed are working.
ESC turns on automatically when you start the engine .

Braking
New brake pads
New b rake pads do not ac hieve the ir full b raking
effe ct during the firs t 2S 0 mi (400 km). They
m ust be "broken in" fi rst .
The b rea k-in period ca n be considerably longe r
for ve hicles w it h cer amic b rake rotors*. However,
you can compensa te fo r the slightly reduced
122
braking force by pressing firmly on the brake
pedal. Avo id heavy braking during the break-in
per iod.
Wear
Brake pad
wear depends large ly on the way the
vehicle is driven and on ope rating conditions .
This is espec ia ll y true if you a re driv ing frequent ly
i n the city and on curves or with a sporty driving
sty le .
Ope rating noi se
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humid ity.
Noises may become mo re apparent at lower
speeds due to the nature of the materials in the
ceram ic brake rotors* .
Effect of water and road salt
In certain situa tions, for e xamp le after d riving
thro ugh water, in heavy rain, a fter over nigh t con
densation or after washing your car, the brak ing
effect can be reduced by moisture or ice on the bra ke rotors and brake pads. The brakes must be
"dried" f irst with a few ca refu l brake app lica
tions.
At higher speeds and with the windshield wipers
turned on, the brake pads press against the brake rotors for a short amount of time. This action,
wh ich is not felt by the dr iver, happens at regu lar .,..

intervals and ensures a better reaction time fo r
the brakes in wet weather.
The braki ng effect can also be red uced if you are
driving on salted roads and you do not apply the b rakes for long periods of time . The layer of salt
on the brake rotors and pads must be worn off
f irst when the brakes are app lied.
Due to its surface, the ceramic bra ke rotor* ab
sorbs moisture in certa in situations. There fore,
there will temporarily be less braking force than
when the brakes are dry . You can compensate for
this by pressing the brake pedal harder.
Cor rosion
L eaving the vehicle parked fo r long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
I f you usually avo id heavy braking or if there is
corrosion present , occasional heavy braking at
high speeds is recommended to clean the brake
rotors and pads
q ,& .
Brak e system malfunct ion
if you notice that the brake pedal travel has sud
denly increased, then a brake c ircui t in the dual
circuit brake system may have malfunctioned. Drive to an authorized Audi dea ler or a uthorized
Aud i Service Facility immediately to have the
problem corrected. On the way there, drive with
reduced speed and keep in mind that you w ill
need a longer distance to stop and you w ill need
to p ress the b rake pedal harde r.
L ow brake fluid level
When the brake fl uid level is low, malfunct ions in
the brake system may occur . The brake f lu id level
is electronically monitored.
Br ak e boost er
The brake booster amplifies the pressure you ap
p ly to the brake peda l. It only works when the en
g ine is running.
A WARNING
- Only apply the brakes for the purpose of
cleaning the brake system whe n road and

traffic conditions permit. You must not en
danger other road users. This increases the
risk of an accident.
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- New brake pads do not ach ieve the ir full
braking effect during the first 250 m i
(400 km). They m ust be "broken in" first.
The break-in per iod ca n be cons iderably lon
ge r fo r vehicles with ceram ic brake rotors* .
H owever, you can compensate fo r the
slightly reduced braking force by pressi ng
fi rm ly on the brake pedal. Avo id heavy b rak
ing du ring the break -in pe riod.
- Ce rtain weathe r and ope rating condi tions
such as driving through water, dr iv ing in
heavy rain o r driv ing after was hing your ve
hicle can impa ir the effect iveness of the
brakes. In the winter, ice may build up on
the brake pads, rotors and drums . Check
these components by braking carefully. Ap
p lyi ng the brakes carefully several times
d ries the b rakes and removes ice build-up .
- The efficiency of the brakes can also be im
pa ired by dr iv ing for long stretches on roads
covered with sa lt without using the bra kes .
You can remove salt deposits from the
b rake rotors and pads by carefully applying
t he brakes several times .
- I f the fron t spoiler is damaged o r yo u install
another spoi ler, make su re the front wheel
b rakes are ven tilated properly . Othe rw ise,
the brake system co uld overheat, which re
duces their effectiveness .
- Fa ilure of a brake circuit impairs brak ing
pe rformance, which increases b raking dis
tance. Avo id driving the vehicle and have it
towed it to the nearest a uthorized Audi
deale r or authorized Aud i Serv ice Facility.
- I f the brake booster is not working, yo u w ill
have to p ress much harder on the brake
pedal to compensate fo r the lack of the
booster.
Q) Note
- Never let the brakes "rub" by pressing the
peda l lightly when braking is not actually

necessary. This causes the brakes to over
heat and increases bra king distance and
causes wear .
- Befo re driving downhi ll a long distance on a
steep hill, decrease your speed and select a
l ower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, b rake in in
t e rvals a nd not continuously .
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit you r vehicle with a front spoil

Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con
ditions . However, in winter we recommend using
winter or all season tires on all four wheels, be
cause this will improve the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 227, Snow chains.
Replacing tires
For vehicles w ith all whee l dr ive, only whee ls w ith
the same rolling circumference should be used .
Avoid using tires with different tread depths
¢ page 218, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain.
_& WARNING
-Also, in vehicles with a ll wheel drive, adapt
your dr iving style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci
dent .
- The braking ability of your vehicle is limited
to the traction of the wheels . In this way, it
is not different from a two wheel dr ive vehi
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be
cause this increases the risk of an accident .
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high. Unlike front wheel drive
vehicles, the engine does not rev higher sud
denly when the vehicle begins hydroplaning .
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci
dent.
