(D Tips
-If the parking brake is set while the ignition
i s sw itched off, the
tG)a indicator light in the
b utton and in the instrument cluster dis­
play - (USA models)/ . (Canada mod­
e ls) will turn off after a certain amount of
time.
- If dr iver's door is opened while the ign ition
i s sw itched on, the pa rking brake sets a uto­
ma tically. T his prevents unin tended ro lling
of the vehicle.
- Occasiona l noises when the parking brake is
set and re leased a re no rmal a nd a re not a
cause for con cer n.
- When the vehicle is par ked, the park ing
b rake goes thro ugh a se lf-test cycle at reg u­
l a r int erva ls. A ny no is es asso ciated with th is
a re normal.
- If t here is a power fa ilure, the p arking bra ke
will not se t if i t is re le a se d, and it will not
r ele ase if it is set¢.&.. See an au thori zed
A udi dealer or au thorized A ud i Service Fa ­
cility for ass istance .

clin es so that the whee ls will roll into the curb
if the ve hicle starts mov ing .
A WARNING
-Always take the vehicle key with you when
leaving the vehicle, even fo r a short period
of time. This applies particularly when chi l­
dren rema in in the veh icle . Otherwise ch il­
dren could start the engine, release the
par kin g brake or operate elect rical eq uip­
me nt such as powe r windows, which in­
c reases the ris k of an acc ident.
- When the vehicle is locked, no one -particu­
larly not children -sho uld rem ain i n the ve­
hicle. Loc ked doors ma ke it more diffic ult

-
for emergency workers to get into the vehi­
cle, which puts lives at risk.
Starting from a stop
The start assist function ensures that the park ­
ing broke is released automatically upon start­
ing.
Stopping and sett ing the parking brake
~ Pull the (D swi tc h to set t he pa rking brake
¢ page 73, fig . 78 .
Starting and automatically releasing the
parking brake
Require ment: the d river 's doo r mus t be closed

~ When you press the acce lerato r pedal, the
parking bra ke is a utomat ica lly re leased and
your veh icle begi ns to move.
When stopp ing at a traff ic signa l or stopping in
c ity traff ic, the par king b rake can be applied . The
vehicle does no t have to be held wi th the brake
pedal. The par king bra ke elim inates the ten dency
to creep when a se lector lever posi tion is engag ­
ed. As soon as you p ress the accelerator pedal,
the parking brake releases a utomat ica lly and the
vehicle starts to move.
Starting on slopes
When star ting on in cli nes, the hill start assist
prevents the vehicle from unintentiona lly rolling
b ack . The b raking force of t he parking brake is
not re leased unti l sufficient dr iv ing force has
been built up at the wheels.
@ Tips
F o r safety reasons, the parking brake is re­
l eased a utomatica lly on ly when the driver 's
safety be lt is fastened and the driver's door is

Intelligent Technology
Electronic stabilization
control (ESC)
Description
The Electronic Stabilization Control (ESC) rein for­
ces driver safety . It reduces the risk of slipping
and improves driving stability. ESC detects crit i­
cal s ituations such as the vehicle oversteering
and understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or reducing eng ine torq ue. When the ESC engages,
the
D1 ind icator light blinks in the instrument
cluste r.
The fo llow ing systems are integrated in the ESC :
Ant i-loc k 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 .
Brake assist system
The brake assist system can decrease brak ing dis­
tance . It increases braking power when the d river
presses the brake pedal quick ly in emergency sit­
uations . You must press and hold t he b rake pedal
until the dangerous situat 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 ahea d is too sm all.
Anti-slip regulation (ASR)
ASR reduces eng ine power when the drive wheels
beg in sp inning a nd adapts the force to the road
conditions . This makes it easie r to start, acceler­
a te and dr ive u p in clines.
Electronic differential lock (EDL )
The EDL brakes w heels that a re spinning and
transfers the drive power to the other drive
wheel or whee ls if t he ve hicle is equipped with a ll
wheel drive*) . T his funct ion is not av ailable at
h igher speeds.
116 I
n extreme cases, ED L automat ically swi tches off
to keep the brake on the braked whee l from over­
heating. The veh icle 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 stabili ze the vehicle by cha nging
the steering torque.
Selective wheel torque control
Se lective w hee l to rque cont rol is used when d riv ­
i ng o n curves. The fron t whee l on the inside of
the curve or bo th whee ls on the inside of the
cu rve are braked se lective ly as needed. This al­
l ows mo re precise driving in cu rves.
Automatic post-collision braking system
The "A utomat ic pos t-coll is io n braking sy stem"
c a n hel p to reduce t he risk of sliding and o f othe r
collisions after an accident . If the a irbag cont rol
module detects a collision a bove a certain vehicle
speed, the vehicle is bra ked by the ESC.
The vehicle does not bra ke automatically if:
- the dr ive r presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is grea ter than the braking force
that wo uld be i nitiated by the system, or
- the ESC, the brake system o r the ve hicle elect ri­
cal system are not func tioning .
A WARNING
- The ESC and its integ rated syste ms can not
o vercome the lim its posed by natural physi ­
c a l la ws. Thi s is espe cial ly import ant on sli p­
pe ry o r we t roads. If the systems beg in act ­
ing to stabilize your ve hicle, yo u should im­
mediately a lter your speed to matc h the
road and traffic condit ions. Do not let the
increased safety pr ovided tempt you into
taking risks . This cou ld increase your risk of

brakes . In the w inte r, ice may b uild up on
the brake pads, rotors and drums. Check
these components by braking ca refu lly . Ap­

- Failure of a brake circuit impai rs b raking
performance, which increases braking dis­
tance . Avoid driving the vehicle . Have it tow ­
ed to the nearest authorized Aud i dealer or
authorized Audi Service Fac ility .
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
acc ident.
- If the brake booster is not working, you will
have to press m uch ha rder on the brake

and increases braking distance and causes
wear .
- Before driving on a long st retch with steep
slopes, reduce your speed and shift to the
next lower gear Th is 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 work ing, you
must press the brake peda l with much more
force than normal.
- If you retrof it your vehicle with a front spo il­
er, wheel covers or sim ilar items, make sure
that the air flow to the fro nt wheels is not
inter rupted . Otherwise the b rake system
can become too hot.
Electromechanical

All wheel drive (quattro)
Applies to: veh icles with all whee l drive
In all wheel drive, all four wheels are powered .
General information
In all wheel drive, the driving power is divided be­
tween all four wheels. This happens automatical­
ly depe nding on your driving behavior as well as
the c urrent road cond itions . Also see
s>
page 116, Electronic stabilization control
( ES C).
The all wheel drive concept is designed for high
engine power . Your ve hicle is exceptionally pow­
erful and has ex cellent driving characterist ics
120
both under normal d riving conditions and on
snow and ice . A lways read and follow safety pre­
ca utions s>
.&..
Winter tires
By using all wheel dr ive, your veh icle has good
forward motion w it h standard t ires in win ter con­
ditions . However, in winter we recommend using
winter or all season tires on
oil four whee ls, be­
ca use this will improve the
broking effect.
Snow chains
I f there are snow ch ain laws , snow ch ains m ust
a lso be used on veh icles with all wheel drive

page 219 , Snow chains .
Replacing tires
For vehicles with a ll w heel drive, o nly wheels with
t h e same ro lli ng ci rcumfe rence sho uld be used.

Offroad vehicle?
You r Audi is no t an off road vehicle - there is not
enough ground clearance. For th is reaso n, avoid
difficul t ter rain . Also see s>
page 251.
A WARNING
-Also, in veh icles with all wheel drive, ad apt
your d riving sty le to the cu rren t road and
traffic conditions. Do not let the increased
safety provi ded tempt you into taking r is k s,
because this inc reases the risk of an acc i­
dent.
- The braking abi lity of your vehicle is limited
to the traction of the whee ls. I n this way, it
is not different from a two w heel drive vehi­
cle . Do not be tempted to accelerate to a
hig h speed when the road is slippery, be ­
cause t his i ncreases the r is k of an accident .
- Note that on wet s treets, the front wheels
can " hydrop la ne" if dr iv ing at spee ds that
are too high. Unlike front w heel d rive
veh icles, t he engine does no t rev h ig her sud­
de nly when t he vehi cle begins hydrop lan ing.
F or this reason, pay atte ntion to the road
conditions rega rdless of your speed to re ­
duce t he risk of an accident .
