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.

(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
c> page 340, Snow chains . .,.

Replacing tires
F or vehicles w it h all whee l dr ive, only wheels w ith
the same ro lling circumference should be used .
Avoid using tires with different tread depths
~ page 332, New tires or wheels.
A WARNING
- Also, in vehicles with all wheel drive, adapt your dr iv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the r isk of an acci
dent .
- The braking ability of your veh icle is limited
to the tract ion of the wheels. In this way, it
is not diffe rent from a two wheel dr ive vehi
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high . Unlike front whee l drive
vehicles, the engine does not rev higher sud
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acc i
dent .
Energy management
Your vehicle is equipped with an intelligent ener
gy management system for distributing electrici
ty . This s ignificantly improves the starting ab ility
and increases the vehicle battery life .
(D Tips
- If you drive short distances frequently, the
vehicle battery may not charge enough
while dr iving . As a resu lt, convenience func
tions for elect rical equipment may be tem
porarily unavailable.
- The vehicle battery will gradua lly drain if
the vehicle is not driven fo r long pe riods of
time, or if electrical equipment is used
when the engine is not running . To ensure
that the vehicle can still be started, the electrica l equipment will be reduced or
switched off.
Intelligent Technology
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
T his vehicle is equipped with an Event Data Re
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa
tions, such as an airbag deployment or hitting a road obstacle, data that will assist in understand
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy
nam ics and safety systems for a short per iod of
t ime, typ ically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
- How various systems in your vehicle were oper
ating;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can help provide a better understand
ing of the circumstances in which crashes and in
juries occur. NO TE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs;
no data are recorded by the EDR under normal
driv ing cond itions and no personal data (e.g .,
name, gender, age, and crash location) are re
corded. However, othe r parties, such as law en
forcement, could comb ine t he EDR data with the
type of personally identifying data routinely ac
quired during a crash investigation.
T o read data recorded by an EDR, special equip
ment is required, and access to the vehicle or the
EDR is needed. In addition to th e ve hicle manu
facturer, other parties, such as law en forcement,
that have the special equipment, can read the in
formation if they have access to the vehicle or the
EDR.
Some state laws restrict the retrieval or down
l oading of data stored by ED Rs installed in a vehi
cle for the express purpose of retrieving data af
ter an accident or crash event without the own- er 's consent .
II>-
145

Intelligent Technology
Audi will not access the EDR and/or similar data
or give it to others -
- unless the vehicle owner (or lessee if the vehi
cle has been leased) agrees; or
- upon the official request by the police; or
- upon the order of a court of law or a govern-
ment agency; o r
- for the defense of a lawsu it through the judicial
discovery process .
- Audi may also use the data for research about
vehicle operation and safety performance or provide the data to a third party for resea rch
purposes without identifying the specific vehi
cle or information about the identity of its own
er or lessee and on ly after the recorded vehicle
data has been accessed.
Vehicle control modules
Your veh icle is also equipped with a num ber of
e lectronic control modules for various veh icle
systems, s uch as engine management, emission
control, airbags, and safety belts.
These electro nic cont rol modules record data
du ring normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capability of these
modules is limited to data (no sound is record
ed). Only a small amount of data is actually re
corded over a very limited period of time, or stor
ed when a system fault is detected by a control module . Some of the data stored may relate to
veh icle speed, direct ion, or brak ing, as well as re
stra int system use and performance in the event
of a crash . Stored data can also only be read and
downloaded with special equipment that is di
rectly connected to the vehicle.
(D Tips
Your vehicle may be equipped with Audi con
nect. Your use of certain Audi connect fea
tures requires wireless services that are pro
vided by a third party wire less te lecommuni
cations provider . For detai ls regarding how in
formation obtained through Audi connect is collected, processed, transmitted, used, and
shared, please see your contract with the
w ireless telecommunications provider.
