technology
The effectiveness of the brakes can also be tem­
porarily reduced if the car is driven for some dis­
tance without using the brakes when there is a
lot of salt on the road in winter. The layer of salt
that accumulates on the discs and pads can be re­
moved with a few cautious brake applications.
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corrosion to form on the discs
if the car is used infrequently, or if you only drive
low mileages without using the brakes very
much.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisable to
clean off the pads and discs by braking firmly a
few times from a moderately high speed ¢.&,..
Faults in the brake system
If the brake pedal travel should ever increase
suddenly, this may mean that one of the two
brake circuits has failed. Drive immediately to the
nearest qualified workshop and have the fault
rectified. On the way to the dealer, be prepared
to use more pressure on the brake pedal and al­
low for longer stopping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the
brake fluid level is too low. The brake fluid level is
monitored electronically.
Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal. It only works when the engine
is running.
& WARNING
- When applying the brakes to clean off de­
posits on the pads and discs, select a clear,
dry road. Be sure not to inconvenience or en­
danger other road users; do not risk an acci­
dent.
- Never let the car coast with the engine
switched off (this can cause accidents).
102 CD
CAUTION
- Never let the brakes "drag" by leaving your
foot on the pedal when you do not really in­
tend to brake. This overheats the brakes, re­
sulting in longer stopping distances and
greater wear.
- Before driving down a long, steep gradient,
it is advisable to reduce speed and move the
selector lever to a lower gear. In this way
you will make use of the engine braking ef­
fect and relieve the load on the brakes. If
you still have to use the brakes, it is better
to brake firmly at intervals than to apply the
brakes continuously.
Note
- If the brake servo is out of action, you must
apply considerably more pressure to the
brake pedal than you normally would.
- If you wish to equip the car with accessories
such as a front spoiler or wheel covers, it is
important that the flow of air to the front
wheels is not obstructed, otherwise the
brakes can overheat.
Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ES() increa­
ses the car's stability. It reduces the tendency to
skid and improves the stability and road holding
of the vehicle. The ESC detects critical handling
situations, such as understeer, oversteer and
wheelspin on the driven wheels. It stabilises the
vehicle by braking individual wheels or by reduc­
ing the engine torque. The indicator lamp Ii] in
the instrument cluster starts flashing as soon as
the ESC intervenes.
The following systems are integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up under
braking until the vehicle has reached a virtual
standstill. You can continue to steer the vehicle
even when the brakes are on full. Keep your foot
•

Downloaded from www.Manualslib.com manuals search engine on
the brake pedal and do not pump the brakes.
You will feel the brake pedal pulsate while the
anti-lock brake system is working.
Brake assist system
The brake assist system can shorten the braking
distance. The braking force is automatically boos­
ted if you press the brake pedal quickly in an
emergency. You must keep pressing the brake
pedal until the danger has passed.
Traction control system (ASR)
In the event of wheelspin, the traction control
system reduces the engine torque to match the
amount of grip available. This helps the car to
start moving, accelerate or climb a gradient.
Electronic differential lock (EDL)
When the EDL detects wheelspin, it brakes the
spinning wheel and directs the power to the oth­
er driven wheel (or wheels on quattro* versions).
This function is not available at high speeds.
To prevent the disc brake of the braked wheel
from overheating, the EDL cuts out automatically
if subjected to excessive loads. The vehicle can
still be driven. The EDL will switch on again auto­
matically when the brake has cooled down.
Steering recommendation
The ESC helps to stabilise the vehicle by changing
the steering wheel torque.
Selective wheel torque control
Selective wheel torque control intervenes when
cornering by braking the wheel(s) on the inside of
the bend individually as required. This enables
precision cornering. The relevant system may not
intervene in the wet or snow.
Multicollision brake assist system
The "multicollision brake assist system" can help
to reduce the risk of skidding and further colli­
sions during an accident. If the airbag control
unit detects that a collision has taken place up-
� wards
of a certain speed, the vehicle is braked by
a'.: the ESC.

technology
The vehicle will not be braked automatically if:
- the driver presses the accelerator,
- the brake pressure applied by pressing the
brake pedal is higher than the brake pressure
initiated by the system,
- or the ESC, the brake system or the vehicle's
electrical system are not fully functional.
A WARNING
- The grip provided by the ESC and the inte­
grated systems is still subject to the physi­
cal limits of adhesion. Always bear this in
mind, especially on wet or slippery roads. If
you notice the systems cutting in, you
should reduce your speed immediately to
suit the road and traffic conditions. Do not
let the extra safety provided tempt you into
taking any risks when driving -this can
cause accidents.
- Remember that the accident risk always in­
creases if you drive fast, especially in cor­
ners or on a wet or slippery road, or if you
follow too close behind the vehicle in front
of you. Please bear in mind that even the
ESC and the integrated systems cannot
compe nsate for the increased accident risk.
- When accelerating on a uniformly slippery
surface (for instance all four wheels on ice
or snow), press the accelerator gradually
and carefully. The driven wheels may other­
wise start to spin (in spite of the integrated
control systems), which would impair the
car's stability and could lead to an accident.
{D Note
- To ensure that the ABS and ASR systems
work properly, all four wheels must be fit­
ted with identical tyres. Any differences in
the rolling radius of the tyres can cause the
system to reduce engine power when this is
not desired.
- The systems can make noises when they in­
tervene.
- If the indicator lamp DJ orr§J appears,
there may be a malfunction ¢ page 14. -

.... Four-wheel
drive
(quattro)
Applies to vehicles: with four-wheel drive
On quattro models the engine power is distrib­
uted to all four wheels.
General notes
On four-wheel drive vehicles, the engine power is
distributed to all four wheels. The distribution of
power is controlled automatically according to
your driving style and the road conditions. Also
refer to ¢ page 102, Electronic stabilisation con­
trol (£SC).
The four-wheel drive is specially designed to
complement the superior engine power of your
Audi. This combination gives the car exceptional
handling and performance capabilities -both on
normal roads and in more difficult conditions,
such as snow and ice. Even so (or perhaps espe­
cially for this reason), it is important to observe
certain safety points¢.&,..
Winter tyres
Thanks to its four-wheel drive, your car will have
plenty of traction in winter conditions, even with
the standard tyres. Nevertheless, we still recom­
mend that winter tyres or all-season tyres should
be fitted on all four wheels when winter road
conditions are expected, mainly because this will
give a better braking response.
Snow chains
On roads where snow chains are mandatory, this
also applies to cars with four-wheel drive
¢ page 234, Snow chains.
Replacing tyres On vehicles with four-wheel drive, all four tyres
must have the same rolling circumference. Also
avoid using tyres with varying tread depths
¢ page 231, New wheels or tyres.
Off-road er?
Your Audi does not have enough ground clear­
ance to be used as an off-road vehicle. It is there­
fore best to avoid rough tracks and uneven ter­
rain as much as possible. Intelligent
technology
_&. WARNING
- Even with four-wheel drive, you should al­
ways adjust your speed to suit the condi­
tions. Do not let the extra safety provided
tempt you into taking any risks when driving
- this can cause accidents.
- The braking ability of your car is limited by
the grip of the tyres. In this respect, your
car is no different from a car without four­
wheel drive. So do not be tempted to drive
too fast on icy or slippery roads just because
the car still has good acceleration in these
conditions -risk of accident!
- On wet roads bear in mind that the front
wheels may start to "aquaplane" and lose
contact with the road if the car is driven too
fast. If this should happen, there will be no
sudden increase in engine speed to warn the
driver, as with a front-wheel drive car. So do
not drive too fast in the wet: adjust your
speed to suit the conditions (accident risk).
Rear spoiler
Applies to vehicles: with automatic rear spoiler
The automatic rear spoiler increases the car's
stability.
Fig. 112 Centre console: Button for rear spoiler
The rear spoiler can be extended or retracted
manually or automatically.
Automatic mode (normal operation)
- Automatic extension: The rear spoiler is auto­
matically extended at road speeds above ap-
proximately 120 km/h.

- Automatic retraction: The rear spoiler is auto­
matically retracted at road speeds below ap­
proximately 80 km/h.
Manual mode
- Manual extension: Briefly press the button
¢ Fig. 112 to extend the rear spoiler all the way
out.
- Manual retraction: At road speeds up to about
20 km/h, press and hold the button to retract
the rear spoiler. At road speeds between
20 km/h and 120 km/h, press the button brief­
ly to retract the rear spoiler all the way back.
& WARNING
- When extending or retracting the rear spoil­
er, please make sure that no persons or ob­
jects are close to the moving spoiler -risk of
injury!
- If the indicator lamp (M appears, the rear
spoiler may have failed to extend due to a
malfunction. In this case, the car's handling
may be different at high speeds. Drive to a
qualified workshop without delay (but do
not exceed 140 km/h) and have the fault
rectified.
CD CAUTION
- If you need to push the vehicle, never put
your weight on the rear spoiler -Risk of
damage!
- To avoid damage to the rear spoiler, you
should not lean on it or apply any other type
of pressure.
- Do not operate the rear spoiler manually
when the boot lid is open or any moving
parts of the automatic rear spoiler are ob­
structed -risk of damage!
Note
Clean the rear spoiler housing every 2 to 3
months. The rear spoiler housing must be free
of ice, snow and leaves in order to operate
correctly.
106 Power
management
This system helps to ensure reliable
starting
The power management controls the distribu­
tion of electrical energy and thus helps to ensure
that
there
is always enough power available to
start the engine.
If a vehicle with a conventional electrical system
is left parked for a long time, the battery will
gradually lose its charge because certain electri­
cal equipment (such as the immobiliser) contin­
ues to draw current even when the ignition is off.
In some cases there may not be enough power
available to start the engine.
Your vehicle is equipped with an intelligent pow­
er management system to control the distribu­
tion of electrical energy. This significantly im­
proves reliability when starting the engine, and
also prolongs the life of the battery.
The main functions incorporated in the power
management system are battery diagnosis, re­
sidual current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the battery. Sensors detect
the battery voltage, battery current and battery
temperature. This enables the system to calcu­
late the current power level and charge condition
of the battery.
Residual current management
The residual current management reduces power
consumption while the vehicle is parked. It con­
trols the supply of power to the various electrical
components while the ignition is switched off.
The system takes the battery diagnosis data into
consideration.
Depending on the power level of the battery, the
individual electrical components are switched off
one after the other to prevent the battery from
losing too much charge and to ensure that the
engine can be started reliably.

technology
event of faults or anomalies in the vehicle data,
only these data are saved. As a rule, faults are
shown by the warning lamps in the instrument
cluster.
Data saved in the control units can only be read
and analysed with special equipment.
A qualified workshop is only able to recognise
and deal with faults by using the relevant saved
data. Among other things, the saved data may
contain the following information:
- Data relating to the engine and the gearbox
-Speed
- Dire ction of travel
- Braking force
- Seat belt warning system data
The control
units
installed will not under any cir­
cumstances record conversations in the vehicle.
On vehicles with an automatic SOS dial system
via a mobile phone or another connected device,
the current location of the vehicle can be trans­
mitted. In accidents where the control units reg­
ister that airbags have been triggered, a signal
can automatically be sent by the system. This de­
pends on the service provider. The signal can only
be sent in areas with sufficient mobile phone cov­
erage.
Event data recorder
Your vehicle is not equipped with an event data
recorder.
In an event data recorder, information about the
vehicle is temporarily saved. In the event of an
accident, you can therefore obtain detailed infor­
mation about the course of events. On vehicles
with an airbag system, accident-related data such
as impact speed, seat belt status, seat positions
and trigger times can be saved. The exact infor­
mation saved depends on the manufacturer.
The installation of an event data recorder is sub­
ject to the agreement of the vehicle's owner. This
process is governed by legislation in some coun­
tries.
108 Reprogram
ming control units
All data for controlling components are saved in
the control units. Some convenience features,
such as one-touch signalling, single door unlock­
ing and display messages can be reprogrammed
using special workshop equipment. If any con­
venience features are reprogrammed, the infor­
mation in this Owner's Manual will no longer be
accurate for the features that have been
changed. We recommend having the reprogram­
ming confirmed by an Audi workshop in the
"Workshop remarks" section of your Service
Schedule.
Your Audi dealer will be able to provide you with
information about possible reprogramming op­
tions.
Event memory
There is a diagnostic connection for reading out
the event memory located in the footwell on the
driver's side of the vehicle. Information regarding
the operation and status of the vehicle's elec­
tronic control units is stored in the event memo­
ry. The event memory should only be read out
and erased by a qualified workshop.
A WARNING
The diagnostic connection must not be used
for other purposes. Incorrect use can cause
malfunctions -risk of accident!
