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. However, you can com­
pensate for the slightly reduced braking force by
pressing firmly on the brake pedal. Avoid heavy
braking during the break-in period .
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 .
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overnight con­ densation or after washing your car, the braking
effect can be reduced by moisture or ice on the
brake rotors and brake pads. The brakes must be
"dried" first with a few careful brake applica­
tions.
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 facilitates 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
118
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 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 gotten larger, then a brake circuit may have
failed. Drive to an authorized Audi dealer or au­
thorized Audi Service Facility immediately to have
the problem corrected. On the way there, drive
with reduced speed and keep in mind that a long
braking distance and increased pressure on the
brake pedal will be necessary.
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.
It only works when the en­
gine is running.
A WARNING
- New brake pads do not achieve their full
braking effect during the first 250 mi
(400 km). They must be "broken in" first.
However, you can compensate for the
slightly reduced braking force by pressing
firmly on the brake pedal. Avoid heavy brak­
ing during the break-in period.
- 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.

All wheel drive (quattro)
Applies to: veh icles with all whee l drive
In all wheel drive, all four wheels are powered .
General information
In all wheel drive, the driving power is divided be­
tween all four wheels. This happens automatical­
ly depe nding on your driving behavior as well as
the c urrent road cond itions . Also see
s>
page 116, Electronic stabilization control
( ES C).
The all wheel drive concept is designed for high
engine power . Your ve hicle is exceptionally pow­
erful and has ex cellent driving characterist ics

both under normal d riving conditions and on
snow and ice . A lways read and follow safety pre­
ca utions s>

Winter tires
By using all wheel dr ive, your veh icle has good
forward motion w it h standard t ires in win ter con­
ditions . However, in winter we recommend using
winter or all season tires on
oil four whee ls, be­
ca use this will improve the
broking effect.

Offroad vehicle?
You r Audi is no t an off road vehicle - there is not
enough ground clearance. For th is reaso n, avoid

A WARNING
-Also, in veh icles with all wheel drive, ad apt
your d riving sty le to the cu rren t road and
traffic conditions. Do not let the increased
safety provi ded tempt you into taking r is k s,
because this inc reases the risk of an acc i­
dent.
- The braking abi lity of your vehicle is limited
to the traction of the whee ls. I n this way, it
is not different from a two w heel drive vehi­
cle . Do not be tempted to accelerate to a
hig h speed when the road is slippery, be ­
cause t his i ncreases the r is k of an accident .
- Note that on wet s treets, the front wheels
can " hydrop la ne" if dr iv ing at spee ds that
are too high. Unlike front w heel d rive
veh icles, t he engine does no t rev h ig her sud­
de nly when t he vehi cle begins hydrop lan ing.
F or this reason, pay atte ntion to the road
conditions rega rdless of your speed to re ­
duce t he risk of an accident .

Important things to do before driving
Safety is everybody 's job! Vehicle and occupant
safety always depends on the informed and care­
ful driver .
For your safety and the safety of your passen­
gers,
be fo re dri ving always:
.. Make sure that a ll lights and signals a re operat­
ing correctly.
.. Make sure that the tire pressure is correct.
.. Make sure that all windows are clean and afford
good vis ibility to the outs ide .
.. Secu re all luggage and other items carefully

.. Adjust front seat , head restraint and mirrors
correctly for your height.
.. Instruct passengers to adjust the head re­
straints accord ing to their height .
.. Make sure to use the right ch ild restraint cor­
rectly to protect children

What impairs driving safety?
Safe driving is directly related to the condition of
the vehicle , the driver as well as the driver's abili­
ty to concentrate on the road without being dis­
tracted.
The driver is responsible for the safety of the ve­
hicle and all of its occupants. If your ability to
drive is impaired, safety risks for everybody in the
veh icle increase and you also become a hazard to
everyone else on the road
¢ ,&. Therefore :
.,. Do not let yourself be distracted by passengers
or by using a cellular telephone.
.. NEVER dr ive when your driv ing ability is im ­
paired (by medications, alcohol, drugs, etc.) .
.. Observe all traffic laws, rules of the road and
speed limits and plain common sense.
.. ALWAYS adjust your speed to road, traffic and
weathe r conditions.
.. Take frequent breaks on long trips. Do not drive
for more than two hours at a stretch .
.. Do NOT drive when you are tired, under pres­
sure or when you are stressed.
A WARNING
Impaired dr iv ing safety increases the risk of
ser ious personal inj ury and death whenever a
vehicle is being used.
Driving safety
Correct passenger
seating positions
Proper seating position for the driver
The proper driver seating position is important
for safe, relaxed driving .
Fig. 120 Correct seating pos it ion
For your own safety and to reduce the risk of in­
jury in the event of an accident, we recommend
that you adjust the driver 's seat to the following
position:
.. Adjust the driver's seat so that you can easily
push the pedals all the way to the floor while
keep ing your knee(s) slightly bent¢,& .
.,. Adjust the angle of the seatback so that it is in
an upright position so that your back comes in
full contact wi th it when you dr ive .
.. Adjust the steering wheel so that there is a dis­
tance of at least 10 inches (25 cm) between the
steering whee l and your breast bone¢
fig. 120.
If not poss ible, see your author ized A udi deal­
ership about adaptive equipment.
.. Adjust the steering wheel so that the steering
wheel and airbag cover points at your chest and
not at your face .
.,. Grasp the top of the steering wheel with your
elbow(s) slightly bent .
.. For adjustable head restraints: Adjust the head
restraint so the upper edge is as even as possi­
b le with the top of your head. If that is not pos­
sible, try to adjust the head restraint so that it
is as close to this posit ion as possible. Move the
head restraint so that it is as close to the back
of the head as possible.
.. Fasten and wear safety belts correctly

Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety belts are neces­
sary, how they work and how to adjust and wear
them correctly.
~ Read all the information that follows and heed
all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death .
- Safety belts are the single most effective
means available to reduce the risk of serious
injury and death in automobile accidents.
For your protection and that of your passen­
gers, always correctly wear safety belts
when the vehicle is moving.
- Pregnant women, injured, or physically im­
paired persons must also use safety belts.
Like all vehicle occupants, they are more
likely to be seriously injured if they do not
wear safety belts. The best way to protect a
fetus is to protect the mother -throughout
the entire pregnancy.
Number of seats
Your Audi has a total of four seating positions:
two in the front and two in the rear. Each seating position has a safety belt .
A WARNING
Not wearing safety belts or wearing them im­
properly increases the risk of serious personal
injury and death.
- Never strap more than one person, includ­
ing small children, into any belt.
It is espe­
cially dangerous to place a safety belt over a
child sitting on your lap.
- Never let more people ride in the vehicle
than there are safety belts available.
Safety belts
-Be sure everyone riding in the vehicle is
properly restrained with a separate safety
belt or child restraint.

Automatic safety belt r etractors
Every safety be lt is equ ipped wi th an automatic
be lt retractor on the shoulder belt. Th is feature
l ocks the belt when the belt is p ulled out fast,
during hard braking and in an accident. The belt
may also lock when you drive up or down a steep
h ill or through a sharp curve. During normal driv­
ing the belt lets you move freely .
Safety be lt pret en sioner s
The safety belts are equipped with a belt preten­
sioner that helps to tighten the safety belt and
remove slack when the pretensioner is activated

Airbag syste m
Always remember, a child seat or infant carrier
installed on the front seat may be struck and
knocked out of position by the rapidly inflating
passenger's airbag in a frontal collision. The air­
bag could greatly reduce the effectiveness of the
child restraint and even seriously injure the child
during inflation.
For this reason, and because the back seat is the
safest place for children -when properly restrain­
ed according to their age and size -we strongly
recommend that children always sit in the back
seat
¢ page 165, Child safety.
.8, WARNING
A child in a rearward-facing chi ld seat insta l­
led on the front passenger seat will be ser i­
ously injured and can be killed if the front air­
bag inflates -even with an Advanced Airbag
System.
- The inflating airbag will hit the child seat or
infant carrier with great force and will
smash the chi ld seat and child against the
backrest, center armrest, door or roof.
- Always install rear-facing child seats on the
rear seat.
- If you must install a rearward facing chi ld
seat on the front passenger seat because of
exceptional c ircumstances and the
PASS EN­
G ER AIR BA G OFF
light does not come on
and stay on, immediately install the rear­
facing child seat in a rear seating position
and have the airbag system inspected by
yo ur Audi dealer.
- Forward-facing ch ild seats insta lled on the
front passenger's seat may interfe re with
the deployment of the airbag and cause se­
rious persona l injury to the child.
.8, WARNING
If, in except ional circumstances, you must in­
stall a forward-facing chi ld restraint on the
front passenger's seat:
- Always make sure the forward-facing se at
has been designed and certified by its man ­
ufacturer for use on a front seat with a pas­
senger front and side airbag .

-
-Never put the fo rward-facing child restraint
up against or very near the instrument pan­
el.
- Always move the front passenger seat to
the highest posit ion in the up and down ad­
justment range and move it back to the
rearmost posit ion in the seat's fore and aft
ad justment range, as far away from the a ir­
bag as poss ible, before install ing the for­
ward-facing chi ld restrain t.
- Always make sure that the safety be lt upper
anchorage is behind the ch ild rest raint and
not next to o r in fron t of the child rest raint
so that the safety be lt will be properly posi­
tioned.
- Ma ke sure that the

.&_ WARNING ,_
If, in exceptional circumstances, you must in­
stall a forward-facing child restraint on the
front passenger's seat:
- Always make sure the forward-facing seat
has been des igned and certified by its man­
ufacturer for use on a front seat with a pas­
senger front and side airbag.
- Never put the forwa rd-facing child restraint
up against or very nea r the instrument pan­
el.
- Always move the front passenge r seat to
the highest posit ion in the up and down ad­
justmen t range and move it back to the
rearmost posit io n in the seat's fo re and aft
adjustment range, as far away from the a ir ­
bag as poss ible, before install ing the for­
ward-facing chi ld restraint.
- Always make sure that the safety be lt upper
anchorage is behind the chi ld rest raint and
not next to o r in front of the c hild restraint
so that the safety be lt will be p roper ly posi­
tioned.
- Always make sure that there is noth ing on
the front passenger seat that will cause the
capacitive passenger detection system in
the seat to signal to the Airbag System that
the seat is occup ied by a person when it is
not , or to signal that it is occupied by some­
one who is heavier than the person ac tually
si tting o n the sea t. T he presence of addi­
tional objects could cause the passenger
front airbag to be turne d on when it should
be
off, or could cause the airbag to work in a
way that is d ifferent from the way it wou ld
have worked without the object on the seat.
- Make sure that the

Damage to the seat may prevent the Advanced
Airbag System for the front passenger seat from
doing its job in a crash.
The front Advanced Airbag System consists
of the following:
-Crash sensors in the front of the vehicle that
measure vehicle acceleration/ deceleration to
provide information to the Advanced Airbag
System about the severity of the crash.
- An electronic control unit, with integrated
crash sensors for front and side impacts. The
control unit "decides" whether to fire the front
airbags based on the information received from
the crash sensors. The control unit also "de­
cides" whether the safety belt pretensioners
should be activated .
- An Advanced Airbag with gas generator for the
driver inside the steering wheel hub.
- An Advanced Airbag with gas generator inside
the instrument panel for the front passenger.
- A capacitive passenger detection system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capacitance of the person in the seat. The information registered
is sent continuously to the electronic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side .
- An airbag monitoring system and indicator
light in the instrument cluster
c::> page 155 .
-A sensor in each front seat registers the dis­
tance between the respective seat and the
steering wheel or instrument panel. The infor­
mation registered is sent continuously to the
electronic control unit to regulate deployment
of the front Adv a need Airbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel
c::> page 188 and tells you when the front
Advanced Airbag on the passenger side has been turned off.
Airbag system
-A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the electronic control unit.
A WARNING ,.__
Damage to the front passenger seat can pre­
vent the front airbag from working properly .
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from functioning properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle .
- Never remove the upholstery from the front
passenger seat.
- Never disassemble or remove parts from the
seat or disconnect wires from it.
- Never carry sharp objects in your pockets or
put them on the seat. The capacitive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat. Such ob­
jects can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
- Never place seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly .
