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.

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
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¢&.

driving
-Adjust the driver's seat and steering wheel
so there is a distance of at least 25 cm be­
tween your breastbone and the centre of the
steering wheel¢ Fig. 182.
- While driving, always hold the steering
wheel with both hands on the outside of the
rim at about the 9 o'clock and 3 o'clock posi­
tion. This reduces the risk of injury if the
driver's airbag inflates.
- Never hold the steering wheel at the 12
o'clock position, or with your hands inside
the rim or on the steering wheel hub. This
could result in serious injuries to the arms,
hands and head if the driver's airbag in­
flates.
- To reduce any risk of injury to the driver dur­
ing a sudden brake application or in an acci­
dent, never drive with the backrest tilted
too far back. The airbag system and seat
belts can only provide proper protection
when the backrest is in an upright position
and the driver is wearing the seat belt in the
correct position. The further the backrest is
tilted back, the greater the risk of injury due
to incorrect positioning of the belt webbing
or an incorrect sitting position.
Correct position for the passenger
The front seat passenger must sit at least 25 cm
away from the dash panel so that the airbag has
enough room to inflate and give maximum pro­
tection in an accident.
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
adjusting the passenger's seat as follows:
"" Adjust the backrest to an upright position so
that your back remains in contact with the up­
holstery.
"" Keep both feet in the footwell in front of the
seat.
"" Fasten your seat belt correctly ¢ page 232.
In exceptional cases you can disable the pas­
senger's airbag via the key-operated switch*
¢page 237.
222 For
detailed information on how to adjust the
passenger's seat, see ¢ page 54, Front seats.
A WARNING
A passenger who is not sitting in the correct
position or who is not wearing a seat belt can
be fatally injured if the airbag is triggered.
-Adjust the passenger's seat so there is a dis-
tance of at least 25 cm between your
breastbone and the dash panel.
- Always keep your feet on the floor when the
vehicle is moving; never rest them on the in­
strument panel, out of the window or on the
seat. If you sit in an incorrect position, you
increase your risk of injury in the event of
sudden braking or an accident. If the airbag
is triggered, you could sustain potentially
fatal injuries by sitting out of position.
- To reduce the risk of injury to the passenger
in the case of sudden braking or an accident,
the passenger should never travel in a mov­
ing vehicle with the backrest reclined. The
airbag system and seat belt can only provide
proper protection when the backrest is in an
upright position and the passenger is wear­
ing the seat belt in the correct position. The
further the backrest is tilted back, the
greater the risk of injury due to incorrect po­
sitioning of the belt webbing or an incorrect
sitting position.
Examples of incorrect seating positions
Occupants can suffer severe or fatal injuries if
they sit in an incorrect position while the vehicle
is moving.
Seat belts can only provide maximum protection
if the belt webbing is positioned correctly. Sitting
out of position greatly reduces the effectiveness
of the seat belts and increases the risk of injury
since the belt webbing is not worn in the position
for which it is designed. The driver is responsible
for the safety of all vehicle occupants, especially
for children.
"" Never allow anyone to sit out of position while
the vehicle is moving ¢,&. . ..,.

Pedal area
Pedals
The pedals must always be free to move and
must never be obstructed by floor mats or any
objects in the footwell.
.,. Make sure that none of the pedals is obstructed
and all of the pedals can be pressed all the way
down to the floor.
... Make sure that all pedals are able to return
freely to their original positions.
Only use floor mats which leave the pedal area
free and can be securely fastened in the footwell.
If one of the brake circuits should fail, increased
brake pedal travel will be required to bring the
vehicle safely to a stop.
A WARNING
Any obstructions that restrict pedal travel can
cause loss of vehicle control and lead to criti-
cal traffic situations.

belts
Seat belts
Why is it so important to
use seat belts?
Seat belts provide effective protection
The common belief that passengers can brace
their weight with their hands in a minor collision
is false.
Fig. 188 Driver with correctly positioned seat belt -good
protection if the brakes are applied suddenly
It is an established fact that seat belts provide
good protection in accidents. Therefore wearing
a seat belt is required by law in most countries.
When worn correctly, seat belts hold the occu­
pants in the best position for maximum protec­
tion ¢ Fig. 188. The seat belts are capable of ab­
sorbing much of the kinetic energy which is gen­
erated in a collision. They also help to prevent
uncontrolled movements which could lead to se­
vere injuries ¢ page 230, Important safety
notes when using seat belts.
If they wear the seat belts correctly, the passen­
gers benefit greatly from the ability of the belts
to reduce the kinetic energy gradually. The front
crumple zones and other passive safety features
(such as the airbag system) are also designed to
absorb the kinetic energy generated in a colli­
sion. Taken together, all these features reduce
the forces acting on the occupants and conse­
quently the risk of injury.
Although these examples are based on a frontal
collision, the physical principles involved are the
same in other types of accidents. This is why it is
so important to put on the seat belts before ev­
ery trip -even when "just driving around the cor-
230 ner".
Please also ensure that your passenger's
seat belt is properly fastened ¢ A.
Seat belts worn correctly have been shown to be
an effective means of reducing the potential for
injury and improving the chances of survival in a
serious accident ¢ page 231, Forces acting in a
collision.
For information on how children can travel safely
in the car refer to¢ page 223, Child seats.
_& WARNING
- Seat belts must be put on before every trip -
even when driving in town. This also applies
to passengers -risk of injury!
- During pregnancy, women should always
ensure they wear a seat belt. The best way
to protect the unborn child is to protect the
mother ¢ page 233, Wearing and adjust­
ing the seat belts during pregnancy.
Important safety notes when using seat
belts
There are a number of safety points concerning
the seat belts which you should remember. This
will help to reduce the risk of injury in an acci­
dent.
_& WARNING
- The seat belts can only provide maximum
protection if the seats are adjusted properly
¢ page 54, Front seats.
- To ensure proper protection, it is important
to wear the seat belts in the correct position
¢ page 232, How to wear seat belts prop­
erly. Ensure that the seat belts are worn ex­
actly as recommended in this chapter. Belts
which are not worn properly can increase
the risk of injury in accidents considerably.
- Do not allow the seat belt to become twis­
ted or jammed, or to rub on any sharp
edges.
- Never allow two passengers (even children)
to share the same seat belt. It is especially
dangerous to place a seat belt over a child
sitting on your lap.

Emission control
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­
rol, otherwise the catalytic converter will be ir­
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­
ing. This allows unburnt fuel to enter the exhaust
system, which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean-
244 ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the symbol
C for the diesel particulate filter lights up
¢page 17.
A WARNING
The exhaust system is very hot when the vehi­
cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission control system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) -risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system -risk of
fire!
Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.

Any loss of coolant normally indicates a leak in
the cooling system. Drive to a qualified workshop
without delay and have the cooling system
checked. If there are no leaks in the system, a
loss of coolant can only occur if the coolant boils
and is forced out of the system as a result of
overheating.
A WARNING
- The cooling system is under pressure. Do
not unscrew the cap on the expansion tank
when the engine is hot: you could be scal­
ded by escaping steam.
- The coolant and coolant additive can be a
health hazard. Store the coolant additive in
the original container in a safe place out of
reach of children -risk of poisoning.
- When working in the engine compartment
be aware that the radiator fan may start
running suddenly, even if the ignition is
switched off- risk of injury!
CD CAUTION
Do not add coolant if the expansion tank is
empty. Air could have got into the cooling
system -risk of engine damage! In this case,
do NOT drive on. Obtain professional assis­
tance.

The brake fluid level is also automatically moni­
tored.
Having brake fluid changed
Have the brake fluid changed regularly by a quali­
fied workshop.
A WARNING
- If the brake fluid level is under the MIN
mark, the effectiveness of the brakes and
therefore the safety of the vehicle may be
impaired -risk of accident! Do not drive on.
Obtain professional assistance.
- Heavy use of the brakes may cause a vapour
lock if old brake fluid is left in the system.
This would seriously impair the effective­
ness of the brakes and the safety of the car
- risk of accident!
CD CAUTION
- If the brake fluid level is above the MAX
mark, brake fluid may escape via the cap on
the reservoir in certain circumstances and
cause damage to the vehicle.
- Brake fluid must not be allowed to come in­
to contact with the vehicle's body, other­
wise it will attack the paintwork.
Battery General warnings for batteries
Because of the complexity of the power supply,
any battery work, such as disconnection, replace­
ment, etc. must be carried out by a qualified
workshop ¢ ,& .
