Intelligent Technology
Intelligent Technology Electronic Stabilization
Control (ESC)
Description
Electronic Stabilization Control (ESC) supports
driver safety. It reduces the risk of slipping and improves driving stability. ESC detects critica l sit­
uations such as when the vehicle is oversteering
and understeering or the wheels are spinning.
The vehicle is stabilized by applying the brakes or
reducing eng ine torque. When the ESC engages,
the
D.1 ind icator light blinks in the instrument
cluste r.
The follow ing systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels 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
with adapt ive c ruise control*, the brake assist
system is more sensitive if the distance detected
t o the vehicle dr iv ing ahead is too small.
Anti-Slip Regulation (ASR)
ASR reduces engine power when the drive wheels
beg in sp inning and adapts the force to the road
conditions . This makes it easie r to start, acceler­
ate and dr ive up hill s.
Electronic Differential Lock (EDL)
EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
other driving wheels. This funct ion is not availa­
b le at higher speeds.
140
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 correctly. ED L
will switch on again automatically when condi­
tions have returned to normal.
Power steering
The ESC can also support vehicle stability
through steering .
Selective wheel torque control
Selective wheel torque control is used when driv­
in g on curves. Brak ing is targeted toward the
whee ls on the inside of the curve as needed. This
a llows more precise driving in curves.
Automatic post-collision braking system
The "automatic post-collis io n braking system"
can help to reduce the risk of sl iding and of addi­
tional collisions after an accident. If the airbag
contro l modu le detects a collision, the vehicle is
braked by the ESC.
The vehicle does not brake automatically if:
-the driver presses the accelerator pedal, or
-the ESC, the brake system or the veh icle electri-
cal system are not functioning.
A WARNING
-The ESC and its integrated systems cannot
overcome the lim its imposed by natura l
p hys ical laws. Th is is espec ially impo rtant
on slippery or wet roads. If the systems be­
gin 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
you into taking risks. This could increase
your r isk of a coll is ion.
-Please note the risk of a collision increases
when dr iv ing fast, especially through curves
and on slippery or wet roads, and when dr iv­
ing too close to objects ahead . The ESC and
its integrated systems cannot always pre­
ve nt co llisions
-there is still a risk of acci­
dents!

Intelligent Technology
A WARNING
You should only switch offroad mode on or
switch ESC/ ASR
off if your driving abilities
and the traff ic conditions perm it. There is a
r isk of slid ing.
- The stabilization function is limited when
offroad mode is switched on. The driving
wheels cou ld spin and the vehicle could
swerve, espec ially on slick or slippery road
surfaces.
- There is no vehicle stab ilizat ion when ESC/
ASR are switched
off .
Hill descent assist
Hill descent assist makes it possible to drive
down a hill at a constant speed.

Hill descent ass ist brakes all fo ur whee ls auto ­
mat ically in o rder to limit speed when dr iving ei­
ther forward or reverse on hills with a g rade from
approximately 6 to 60%. The wheels wi ll not lock
up because the ABS remains activated .
When hill descent ass ist is on, the speed yo ur ve­
hicle was traveling when it ente red the hill is
maintained .
It is only possible to switch on the
assist when driving slower than 37 mph (60 km/
h). The assist begins shortly after you start driv­
ing and continues up to approximate ly 19 mph
(30 km/h) . The driver can increase or decrease
the vehicle speed with in these limits by pressing
the accelerator or brake pedal.
142
However, there must be enough traction . Hi ll de­
scent assist
cannot function as expected , if for
example the hill is icy or if the surface is loose
c> ,& .
Active regulation of a speed up to approximate ly
19 mph (30 km/h) is signaled in the instrument
cluster by an indicator light
• . The ii indicator
li ght turns on in the ready mode.
The system does not work at speeds between ap­
proximately 19 and 37 mph (30 and 60 km/h).
The system is then in ready-mode. Th is is indicat­
ed by the LED in the button turning on. The sys­
tem automat ically switched off when you dr ive
faster than 37 mph (60 km/h) . The LED w ill also
turn off in this scenar io .
Hill descent assist is automatically activated un­
der the follow ing condit ions:
- the LED in the button turns on
- the vehicle speed is lower than 19 mph (30 km/
h)
-the hill angle is at leas t approximate ly 6%
A WARNING
- Always adapt your speed to the weathe r,
road and traffic conditions . Do not let the
increased safety provided tempt you into
taking risks, because this increases the risk
of an accident .
- The hill descent assist system cannot over­
come the laws of phys ics. Your driving style
must always be adapted to the current road
and traffic cond itions .
- Hill descent ass ist may not be ab le to hold
your veh icle at a constant speed under all
conditions while dr iv ing on a hill (fo r exam­
p le if ground under the vehicle is loose).
Brakes
New brake pads
-
New brake pads do not achieve their full braking
effect during the first 250 mi (400 km). They
must be "broken in" first . H owever, you can com ­
pensate for the slightly reduced braking force by
pressi ng fi rml y on t he brake pedal. Avo id heavy
braking during the break-in period .
..,.

u co ..... N r--­N ..... 0 <( 0 00
Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy rain or after washing
your car, the braking effect may be reduced due
to moisture or ice on the brake rotors and brake
pads. The brakes must be "dried" first with a few
careful brake applications.
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,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at high speeds is recommended to clean the brake
rotors and
pads¢ ,&..
Brake system malfunction
If you notice that the brake pedal travel has sud­
denly increased, then a brake circuit in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
Intelligent Technology
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
is electronically monitored.
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
& WARNING
= -
- Only apply the brakes for the purpose of
cleaning the brake system when 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.
- Never place objects in the driver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You would not be able to use the ped­
als if sudden driving or braking maneuvers
were needed, which increases the risk of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se­
curely fastened in the footwells.
- To reduce the risk of injury, do not place
your foot under the brake pedal.
@ Note
- Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, brake in in- tervals and not continuously.

Intelligent Technology
(D Tips
-If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoil­
er, whee l covers or similar items, make sure
that the a ir flow to the front wheels is not
in terrupted. Otherw ise the brake system
can become too hot .

All-wheel drive (quattro)
General information
In all wheel drive, the driv in g power is distribut­
ed between all four whee ls when needed. This
happens automatically depending on your driving
behavior as well as the current road conditions.
Also see
c> page 140 , Electronic Stabilization
Con trol (ESC).
The all-whee l drive system distributes the driving
power variably to the front and rear axle. It works
together with selective wheel torque control,
which activates when driving through curves
c> page 140. With the sport differential*, power
distribution to the rear wheels is variable and can
be adjusted using the drive select
c>poge 125 .
The all wheel drive concept is designed for high
engine power . Your vehicle is excep tionally pow­
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions ¢.&. .
Winter tires
By using all wheel dr ive, your veh icle has good
forward motion w ith standard tires in winter con ­
ditions. However, using winter or all season t ires
o n oil four wheels in the winter is recommended,
because this w ill imp rove the braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on veh icles with all wheel drive
