Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDR's are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, eng ine function, em is­
sion control, as well as for the airbags and
safety belts.
These electronic contro l modules also record
vehicle-re lated data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited pe riod of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidd ing and loss of vehicle control. It works
only when the engine is running. ESC detects certain difficult driving situat
ions, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering assistance to help hold the
vehicle on the driver's intended course. The in­
dicator light
G) in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations.
It is important to remem­
ber that ESC cannot overcome the laws of
physics. It wi ll not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of
dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it wou ld on the dry surface . If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered.
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations as at lower
speeds.
Always adjust your speed and driving style to
road , traffi<;: and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available tract ion, or keep a vehicle
on the road if road departure is a result of
driver inattention . Instead, ESC improves the
poss ibility of keeping the vehicle under con­
t rol and on the road during extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection . If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.
ESC includes and/or works together with the
anti- lock brake system (ABS), brake assist sys-
tem and anti-slip regu lation (ASR). ESC is .,..

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru . Be sure to
switch ESC on again when you no longer need
less traction.
Anti -loc k brak ing s ystem (ABS )
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking. Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is helping you to brake the vehicle.
B rake ass is t system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Elect ronic diff erential lock (EDL )
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot ove rcome
t he laws of physics. This is espec ia lly im ­
portant on slippery or wet roads.
If the
systems begin act ing to stab ilize your ve­
hicle, you should immediately change
yo ur speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligen t technolog y 151
to take risks. Doing so will increase the
risk of a loss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when driving too close to vehicles up ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot preven t coll i­
sions.
- Always ac celera te with spe cial care on
even, smooth s urfaces su ch as those th at
are wet or covered with ice and snow.
The drive wheels can spin even with these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems described are working.

down continuously. Pump the brakes at inter ­
va ls.
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Moistu re or road salt
Under certain conditions, for examp le, when
d riving through water or ve ry heavy rain, or
even after washing your vehicle , the bra king
effect can be reduced due to moisture (o r in
freezing conditions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings.
The effectiveness of the b rakes can be reduced
when the vehicle is driven on a salt -covered
road and the brakes are not used. Likewise,
you clean off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
plications of the brake

Co rrosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or
only for short trips with little use of the brakes.
If the brakes are not used frequently, or if cor­ rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
f irmly a few times from a moderately high
speed

aware of when changing a tire?.
A WARNING
-- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r road use rs must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long or too often. This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance .
- Under certain climatic and operat ing
conditions such as passing through wa­
ter, dr iving in heavy rain or after washing
the vehicle, the effectiveness of the b rakes can be reduced. In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs and drums. Carefully app ly bra kes
for a test . Brakes will dry and ice coat­
ings will be cleaned off after a few care­
fu l brake applications.
- Driving for an extended period of time on salt-covered roads without using your brakes can a lso affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few cautious
brake applications .
- If you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
f low to the front brakes is not obstruct-
ed. Otherwise the brake system could
Ill>

overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dealer or qualified workshop .
- Never let the vehicle roll to a stop w ith
the engine shut off.
- If the brake booster is not working, for
example when towing your ve hicle, or
because the brake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
Electro-mechanical
power assist
The electro-mechanical power assist helps
the driver when steering.
The degree of power assist is electronically
matched to vehicle speed.
The power steer ing system ass ists the driver
so that he can stee r the veh icle w ith red uced
phys ica l effort.
Power steering w ill not work if the engine is
off. As a result, the steering wheel w ill be hard
to turn.
& WARNING
If the system develops a prob lem, you
must seek qualified professional assis­
tance.
(D Note
-
If there is an electronic malfunct ion, ser­
votronic
wi ll sti ll function like a conven­
tional power steering system, providing a
constant steering support force that is no
longer proportionate to the vehicle speed.
This is most noticeable when turning the
steer ing wheel at low speeds (for example
when parking), -more effort will be re­
quired than usual.
Int ellig ent technolog y 155
-Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authorized Audi dea ler as soon as
possible.
- If a steering malfunction occurs, this is
signaled with the,~ , or .• indicator
lights and a warn ing tone, see.
(D Tips
- If the power steering system sho uld fail,
or if the engine is not running (for exam­
ple, while being towed), you will still be
able to steer the vehicle. However, more
effort will be required to do so.
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately.

General information
With a ll-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depend ing on your driving style and the road
conditions at the time. See also
c::> page 1 SO.
The all-whee l dr ive concept is des igned for
high eng ine power. Your veh icle is except ion­

teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions

Winter tires
When dr iving in the winter, your vehicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
all fou r
wheels. See also c::> page 211, Winter tires. ..,_

Snow cha in s
Where t ire cha ins are mandatory on certain
roads, this normally a lso applies to vehicles
with a ll-wheel drive ¢
page 212, Snow
chains .
Replacing wheels /t ir es
Vehicles with all-wheel drive must a lways
have tires of the same size. Also avoid t ires
with different tread depths. For details see
page ~
page 207, New tires and replacing
tires and wheels.
Off -Ro ad dri ving?
Your Aud i does not have enough ground clear­
ance to be used as an off -road veh icle.
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
¢ page 160.
A WARNING
Always adjust your driving to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel dr ive tempt you into
taking extra r isks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should the refore not dr ive at excessive
speeds on icy or slippery road su rfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning) .
If this should occ ur, you
will have no warning from a sudden in ­
crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions. -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventional energy system
is not driven for a long per iod of t ime, the bat­
tery is discharged by idling current consumers (e .g. immobilize r). In certa in circumstances it
can resu lt in the re be ing insufficient energy
available to start the engine.
Intelligent energy management in your vehi­
cl e handles the distribution of e lectr ica l ene r­
gy . Start ing ability is ma rkedly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
b att ery diag nosis, idlin g curre nt manage ­
m ent
and dynamic en erg y manag em ent .
Battery di agnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current state o f charge and the power of the battery .
Idling current managem ent
Idling current management reduces energy
consumption while the vehicle is standing .
With the ig nition sw itched off, it controls the
energy supply to the various electri ca l compo ­
nents. Da ta from ba ttery diagnos is is cons id ­
ered.
Depend ing on the batte ry's state of cha rge,
individual cons ume rs a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energ y manag ement
While the vehicle is being driven, dynamic en­
ergy ma nagement distr ibutes the energy gen­
era ted accord ing to t he needs of the individ u-
al components .
It regula tes consumption, so
that more electrical energy is not being used ..,.

Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental in ­
fluences is
frequent washing and waxing . How
often this is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle paint, the more lasting their destructive ef­
fects wi ll be .
High tempera tures, as from expos ure to in­
tense sunlight, intensify the corrosive e ffect
particularly when humidity is high as well.
Under certa in ci rc u mstances,
we ekly washing
may be necessary. Unde r othe r cond it ions, a
monthly washing and waxing may be ade ­
quate.
After the winter, the unders ide of the vehicle
sho uld be thoro ughly washed p re ferab ly in a
pro fessional ca r wash.

Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sig n of the fac ility, the filtering of the wash
water, the type of wash and care mater ial , etc.
If the paint has a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a ca r wash, be s ure to
take the usual precautions such as closing the
windows. Remove antenna if applicable .
If you have installed additional accessories on
the vehicle -such as spoilers, e tc. -it is best to
ask the car wash operator i f these should be
removed .
