" N .... 0 0 :c ' Intelligent Technology Electronic Stabilization
Control (ESC)
Description
The ESC increases driving safety. It reduces the
risk of slipping and improves driving stability.
ESC detects critical situations such as when the
vehicle is oversteering and understeering or the
wheels are spinning. The vehicle is stabilized by
applying the brakes or reducing engine torque .
When the ESC engages,
the G1 indicator light
b links in the instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the whee ls 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 system
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 situat ion is over . In veh icles
w ith adaptive cruise contro l*, the brake assist
system is more sensitive if the distance detected
to the vehicle dr iv in g ahead is too small. On
ve hicl es w ith activated and functioning night vi­
sion assist*, the brake assist system can respond
more sensitively if there is a warning .
Anti-Slip Regulation (ASR)
ASR reduces engine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
EDL applies the brakes to a wheel that starts
sp inn ing and transfers the drive power to the
other driving wheels. This functio n is not availa­
ble at higher speeds.
Intelligent Technology
In extreme cases, EDL automatica lly switches off
to keep the brake on the braked whee l from over ­
heating. The vehicle is still working correct ly. ED L
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
T he ESC he lp s to stabilize the vehicle by changing
the steering torque .
In veh icles with dynamic steer ing*, ESC also
helps to stab ilize the steer ing in crit ica l situa­
tions.
Selective wheel torque control
Selective wheel torque control is used when driv­
in g on curves.
The front wheel on the inside of the curve or both
wheels on the inside of the curve are braked se­
lectively as needed. This allows more precise driv­
in g in curves . The applicable system may not acti­
vate when dr iv in g in wet or snowy conditions .
Automatic post -collision braking system
Th e "automat ic post-collis ion braking system"
can help to reduce the risk of sliding and of addi­
t iona l co llisions after an acc ident. If the airbag
control module detects a co llision above a certa in
vehicle speed, the veh icle is braked by the ESC.
The vehicle does not brake automatically if :
- the dr iver presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri ­
cal system are not functioning.
A WARNING
,--
- The ESC and its integrated systems cannot
overcome the lim its imposed by natural
p hys ical laws. This is especially important
on slippery or wet roads. If the systems be­
g in acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt
127

Intelligent Technology
you into taking risks. T his could increase
your risk of a co llision.
- 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 risk of acc i­
dents!
- Press the accelerator pedal carefully when
acce lerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
Switching on and off
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision.
(D Tips
- Th e ABS and ASR only function correct ly
when a ll four wheels have a simi lar wear
condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

" N .... 0 0 :c ' Brakes
New brake pads
New brake pads do no t ac hieve t heir f ull b raking
effect during the firs t 25 0 mi (4 00 km). They
must be "b roken
in" fi rst . The b rea k-in per io d can
be considerably longe r for vehicles with ce ram ic
brake roto rs*. However, yo u can compensate for
the slightly reduced br aking fo rce by p ressing
firm ly on the brake pedal. Avo id heavy braking
d uring the brea k-in period .
Wear
Brake pad wear depends largely on the way the
ve hicle is driven and on operat ing cond itions.
This is especially true if you are driving frequently
i n the c ity and on curves o r with a sporty driving
style .
Operating noise
Noises may occur when bra king depend ing on the
speed, braking force and outs ide cond itions s uch
as temperature and humidity .
Noises may become more appare nt at lowe r
speeds d ue to the nature of the mater ia ls in the
ceramic brake rotors*.
Effect of water and road salt
I n ce rtain s it u at ions, for ex ample a fter dr iving
throu gh water, in heavy ra in, afte r overnig ht con ­
densat io n or after washing your car, the bra king
effect can be red uced by moisture or ice on the
brake rotors and b ra ke pads. The brakes must be
"dr ied" fi rst w it h a few careful brake applica­
tions .
At highe r speeds and with the windsh ie ld w ipers
turned on, the brake pads press aga inst the brake
rotors for a sho rt amount of time. T his action,
which is not felt by the d rive r, happens a t regular
in te rvals a nd ens ures a bette r reac tion time fo r
the bra kes in wet weat her.
The braking ef fect can also be reduced if you are
d riving on salted roads and you do not apply t he
b rakes fo r long pe riods of time . The laye r of sa lt
on the br ake ro to rs and pads must be wo rn off
fi rs t when the br akes are app lied.
Intelligent Technology
Du e to its s urface, the ceram ic b rake rotor * ab ­
sorbs moistu re in ce rtain s ituations. The refore,
t h ere w ill tempora rily be less brak ing fo rce t han
whe n the brakes are d ry . Yo u can compensate for
t hi s by press ing t he b rake pedal harder.
Corrosion
L eaving t he vehi cle pa rked fo r lo ng p eriods o f
time, low mileage and avoidin g heavy b raking
can contrib ute to corros ion on the b rake roto rs
and to dirty brake pads.
If you usu a lly avoid heavy bra king or if the re is
cor rosion prese nt, occasiona l heavy bra king at
high speeds is recommended to clean the b ra ke
r oto rs and pads

Brake system malfunction
If
you notice that the br ake pe dal trave l has sud ­
denly in crease d, then a brake circuit in the dua l­
c ir cuit b rake system may have malfu nctioned .
Drive to an authorized A udi dealer or autho rized
Audi Se rvice Facility immed iate ly to have the
prob lem cor rected . On the way there, drive w ith
red uced speed and kee p in mind that you will
need a longer dis tance to stop an d you will need
to press the bra ke pe dal harder.

ALL wheel drive (quattro)
In all wheel drive, all four wheels are powered .
General information
In all wheel drive, the driving power is divided be­
tween a ll four wheels . This happens automatical ­
ly depending on your driving behavior as well as
the current road conditions. Also see
<=> page 12 7, E lectronic Stabilization Control
(ESC) .
With the sport differential*, power distri­
bution to the rear wheels is variable and can be
adjusted using the drive select
<=>page 111.
The all wheel drive concept is designed for high
engine power . Your vehicle is exceptionally pow­
erful and has excellent driving characterist ics
both under normal driving conditions and on
snow and ice. Always read and follo w safety pre ­
cautions<=>.&. .
Winter tires
By using all wheel drive, your vehicle has good
forward mot ion 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 cha in laws, snow chains must
a lso be used on vehicles with all wheel drive
<=> page 298, Snow chains .
Intelligent Technology
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid using tires with different tread depths
<=> page 2 90, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficu lt terrain .
A WARNING ~ -
-Also, in vehicles with all whee l drive, adapt
your driving style to the current road and
traffic cond itions. Do not let the increased
safety prov ided tempt you into taking r isks,
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 drive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slipp ery, be­
cause this incr eases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydrop lane" if dr iv in g at speeds that
are too high . Unlike front wheel drive
vehicles, the engine does not rev higher sud­
den ly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a vehicle with a conventiona l energy sys­
tem is not driven for a long t ime, the vehicle bat­
te ry is drained by equipment (for example, the
immobilizer). In certain circumstances, there
cou ld may not be enough energy to start the en-
gine.
