wards (a parking space has been detected)
The section below describes how to park parallel
to the roadside. The procedure for parking per­
pendicular to the roadside is similar.
Important: For the best parking result, you
should maintain a distance of approx. 1 metre to
the row of parked cars.
� Activate the turn signal for the side on which
you want to park.
� To park parallel to the roadside, drive forwards
at not more than 30 km/h. Or:
� To park perpendicular to the roadside, drive
forwards at not more than 20 km/h.
� The system will display a parking space when it
finds one¢ Fig. 118. Please check that the
parking space is suitable for your vehicle.
If you exceed a speed of about 50 km/h, the park
assist will be switched off.
The park assist will display a parking space only if
it is Long and wide enough for the vehicle.
If you operate the left turn signal, the display
will show the left side of the road (and vice-ver­
sa).
@ Note
- You can activate the park assist after you
have already driven past a parking space (as
Long as you were driving slowly enough). To
do so, press the I@ button and operate the
turn signal.

- The best parking results will be achieved if
you position the vehicle as parallel as possi­
ble to the line of parked cars or the kerb be­
fore you start the actual parking manoeu­
vre.
-If there are suitable parking spaces on both
sides of the road (for instance on a one-way
street), you can change the direction of the
turn signals to park on the other side, even
if you have already activated the park assist.

Electronic stabilisation
control (ESC)
Description
The electronic stabilisation control (ESC) 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 DJ 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
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).
0 This
function is not available at high speeds.
� To
prevent the disc brake of the braked wheel
8 from
overheating, the EDL cuts out automatically
"
Vl Intelligent
technology
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
the ESC.
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
113

Downloaded from www.Manualslib.com manuals search engine Intelligent
technology
ESC and the integrated systems cannot
compensate 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.
@ Note
- The ABS and ASR systems can only work
properly if all four tyres have a similar de-
Switching on/off gree of
wear. Any differences in the rolling
radius of the tyres can cause the system to
reduce engine power when this is not de­
sired.
- The systems can make noises when they in­
tervene.
The ESC is switched on automatically when the engine is started.
the ESC is restricted or switched off, and the ve­
hicle is stabilised to a greater or lesser degree.
In the following special situations, it may be ad­
visable to switch on the sport mode to allow a
certain amount of wheels pin:

it
- Driving in deep snow or on loose surfaces
- Driving with snow chains

WARNING
You should switch on the sport mode or
switch off the ESC/traction control system
(ASR) only if your driving ability and the traf­
fic conditions allow you to do so safely -dan­
ger of skidding!
- The stabilising function is restricted when
sport mode is switched on. The driven
wheels may start to spin, causing the vehi­
cle to lose grip, in particular on slippery or
wet roads.
- When the ESC/traction control system
(ASR) is switched off, the vehicle will not be
stabilised.
@ Note
- The ESC/traction control system (ASR) can­
not be switched off and the sport mode can­
not be switched on when the cruise control
system* is on.
- In the event of a malfunction in the rear
spoiler system or the Audi magnetic ride, it
may not be possible to switch off the ESC/
ASR or switch on the sport mode.
Brakes
New brake pads
New brake pads do not give full braking effect for
the first 400 km, they must first be "bedded in".
However, you can compensate for the slightly re­
duced braking effect by applying more pressure
on the brake pedal. Avoid placing a heavy load on
the brakes during the running-in period.
Wear
The rate of wear on the brake pads depends a
great deal on how you drive and the conditions in
which the vehicle is operated. Negative factors
are, for instance, city traffic, frequent short trips
or hard driving with abrupt starts and stops.
Noises
Brake noise may develop in certain situations, de­
pending on the speed, braking force and ambient
conditions (such as temperature and relative hu­
midity). Intelligent
technology
Effect of moisture and salt
In certain conditions, such as in heavy rain, early
morning dew, or after washing the car or driving
through water, the full braking effect can be de­
layed by moisture (or in winter by ice) on the
discs and brake pads. The brakes should be
"dried" by pressing the pedal to restore full brak­
ing effect.
When you are driving at higher speeds with the
windscreen wipers on, the brake pads are very
briefly brought into contact with the brake discs.
This automatic process which goes unnoticed by
the driver is carried out at regular intervals and is
intended to improve braking response in wet con­
ditions.
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
removed 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 ¢ A.
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.
llll-

Brake servo
The brake servo amplifies the pressure you apply
to the brake pedal.
A 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).
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 select a
lower gear. In this way you will make use of
the engine braking effect and relieve the
load on the brakes. If you still have to use
the brakes, it is better to brake firmly at in­
tervals than to apply the brakes continuous­
ly.
� 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.

Electro-mechanical power steering assists the
driver when steering.
The degree of power assistance is adapted elec­
tronically, depending on the speed.
116 Warning/indicator
lamps and driver
messages
• Steering: fault. Please stop vehicle
If the warning lamp Lights up permanently and
the message appears, there may be a power
steering failure.
Stop the vehicle in a safe place as soon as possi­
ble. Do NOT drive on. Obtain professional assis­
tance.
� Steering: fault. You can continue driving
If the indicator lamp lights up, the steering re­
sponse may be heavier or Lighter than usual. In
addition, it is possible that the steering wheel
will be off centre when driving in a straight Line.
Drive slowly to a qualified workshop and have the
fault rectified.
('!)) Note
You can drive on if the warning/indicator
lamp . or� Lights up only briefly.
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 113, Electronic stabilisation con­
trol (ESC).
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¢&.

CX) 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 2 5 7, 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 254, New wheels or tyres.
Off-roader?
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.
A 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). Intelligent

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 vehicle battery
will gradually lose its charge because certain
electrical equipment (such as the immobiliser)
continues 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 vehicle battery.
The main functions incorporated in the power
management system are battery diagnosis, re-
118 sidual
current management and dynamic power
management.
Battery diagnosis
The battery diagnosis function constantly regis­
ters the condition of the vehicle battery. Sensors
detect the battery voltage, battery current and
battery temperature. This enables the system to
calculate the current power level and charge con­
dition of the vehicle battery.
Residu al 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 vehicle bat­
tery, the individual electrical components are
switched off one after the other to prevent the
vehicle battery from losing too much charge and
to ensure that the engine can be started reliably.
Dynamic power management
While the vehicle is moving, this function distrib­
utes the available power to the various electrical
components and systems according to their re­
quirements. It ensures that on-board systems do
not consume more electrical power than is being
generated, and thus maintains the maximum
possible vehicle battery power level.
.
1 Note
- The power management system is not able
to overcome the given physical limits.
Please remember that the power and life of
the vehicle battery are limited.
- If the indicator lamp ri'.J ¢ page 15 appears,
the starting ability may be impaired.
Points to remember
Starting ability has first priority.
Short trips, city traffic and low temperatures all
place a heavy load on the vehicle battery. In
these conditions a large amount of power is
