Smart Technology Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
This 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 a irbag 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
namics and safety systems for a short per iod of
time, typically 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 he lp provide a better understand­
ing of the circumstances in which crashes and in­
juries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e .g.,
name, gender, age, and crash location) are re­
corded. However, other parties, such as law en­
forcement, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
To read data recorded by an EDR, special equip­
ment is requ ired, and access to the vehicle or the
E DR is needed. In addition to the vehicle manu­
facturer, other parties, such as law enforcement,
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 retr ieval or down­
l oading of data stored by EDRs installed in a vehi­
cle for the express purpose of retriev ing data af-
Smart Technology
ter an accident or crash event without the own­
er's consent.
A udi will not access the EDR and/or similar data
o r give it to others -
- unless the vehicle owner (or lessee if the veh i­
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; or
- for the defense of a lawsuit through the judicial
discovery process .
- Audi may also use the data for research about
veh icle operation and safety performance or
provide the data to a th ird party for research
purposes without identifying the spec ific vehi­
cle or information about the ident ity of its own­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equ ipped with a number of
electron ic contro l modules for various vehicle
systems, such as eng ine management, emission
control, airbags, and safety belts.
These electronic control modules record data during norma l vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capabil ity of these
modules is lim ited to data (no sound is reco rded).
Only a small amount of data is actua lly recorded
over a very limited period of time, or stored when
a system fau lt is detected by a contro l module.
Some of the data stored may relate to vehicle
speed, direction, or braking, as well as restraint
system use and performance in the event of a
crash . Stored data can also only be read and
downloaded w ith specia l equipment that is di­
rectly connected to the vehicl e.
(D Tips
Your vehicle may be equipped with Audi con­
nect. Your use of certain Audi connect fea­
tures requires wireless serv ices that are pro­
v id ed by a third party wire less telecommuni­
cations provider . For detai ls regard ing how in­

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing . ESC detects certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
d itions 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. Whe n
there is a section of d ry road that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs to help keep the vehicle going in the in­
tended direction. If you are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 153 or ¢page 171, fig. 154. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .

M N

rl I.O
"' N
"' rl
In extreme cases, EDL a utomatica lly switches off
to help keep the brake on the braked whee l from
overheating. EDL w ill switch on again automati ­
cally when conditions have returned to normal.
Steering re commendat ion
The ESC helps to stabilize the ve hicle by chang ing
the steering torque.
I n vehicles with dynamic steeri ng*, ESC also
h e lps to stabilize the steering in critical s itua­
tions .
Electronic interaxle differential lock* /
sel ectiv e wheel torque control*
The electron ic in teraxle d iffe ren tial lock (front
wheel drive) or the selective wheel torq ue contro l
(all wheel drive) operates when driving through
curves. The front whee l on the ins ide of the cu rve
or both whee ls on the inside of the curve are
braked selectively as needed. Thi s allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions .
_&, WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
ci al ly impo rtant on slippe ry or wet roads. If
the sys tems begin acting to stabilize your
Switching on/off
Smart Technology
veh icle, you shou ld immediately change
your speed to matc h the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks . Do ing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle inc reases when dr iving
too fast, espec ially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead . The ESC and its
integrated systems cannot a lways prevent
coll isions -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth su rfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that can not always help to reduce
the risk of loss of vehicle cont rol.
{!) Tips
-ABS and ASR only work correct ly when a ll
four wheels are equipped w ith ident ica l
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine.

Braking
What affects broking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢,&. . You can com­
pensate for this slightly reduced braking power
by pushing harder on the brake pedal. Avoid
heavy braking loads during the break-in period.
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear, depending largely on operating con­
ditions and driving habits~,&. . On vehicles that
are either driven most ly in stop-and -go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi dealer more of­
ten than specified in the
Warranty & Mainte­
nance booklet .
Failure to have your brake pads
i nspected can result in reduced brake perform­
ance .
On steep slopes, you should use the braking ef­
fect of the engine . This way, you prevent unnec­
essary wear on the brake system. If you must use
your brakes, do not hold the brakes down contin­
uously. Pump the brakes at intervals.

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 situat ions, for example after driving
through water, in heavy ra in, after overn ight con­
densat ion 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 carefu l brake applications.
At higher speeds and with the w indshie ld w ipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This occurs at
regular intervals without the driver noticing and
provides for better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road
and the brakes are not used. Likewise, you clean
off accumulated salt coating from brake discs
and pads with a few cautious applications of the
brake ¢.& .
Corrosion
There may be a tendency for dirt to build up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes.
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is advisab le to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed¢.&.
Faults in the brake system
If you should notice a sudden increase in brake
pedal trave l, then one of the two brake circuits
may have failed

the wheel may be removed for this inspection
c:> page 226, Replacing wheels.
_8 WARNING "'---
-New brake pads don't have the best stop­
pin g power and must be "broken-in" during
the initial 250 miles (400 kilometers). You
can compensate for this by press ing the
brake pedal more firmly. This also applies
later when new pads are installed.
-
- You shou ld perform braking maneuvers for
the purpose of cleaning the brake system
only if road conditions permit. Other road
users must not be put at r isk -you may
cause an acciden t!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving 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 resting your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over­
heat, premature wear and increased stop­
p in g distance.
- Under certain cl imatic and operat ing condi­
tions such as passing through water, dr iv ing
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
b rak e pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on
salt -covered roads wi thout using your
brakes can a lso affect braking efficiency .
173

Smart Technolog y
Clean off accumulated salt coating from
brake discs and pads w ith a few carefu l
brake applications .
- If you damage the front spoiler, or if you in­
stall a d ifferent spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc ­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake c ircuit will impair the
braking capab ility result ing in an increased
stopp ing distance. Avoid driving the veh icle
and have it towed to the nearest autho rized
Audi dealer or qualified workshop.
- Never let the vehicle ro ll to a stop with the
engine shut off .
- If the brake booster is not work ing, the
brake pedal must be pressed considerably
harder to make up for the lack of booste r as­
sistance .

The all-wheel drive concept is designed for high
engine power . Your vehicle is exceptionally pow­
erful and has excellent driving character istics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions <=>
,&.
Winter tire s
When driving in the winter, your vehicle with all­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be advisa­
ble to mount w inter tires (or all-season tires) for
improved driveability and braking: these tires
must be mounted on
all four wheels. See also
<=> page 220, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally also applies to vehicles with
all-wheel drive <=>
page 220, Snow chains.
Replacing wheels/tires
Vehicles with all-wheel drive must a lways have
tires of the same size. Also avoid tires with differ­
ent tread depths. For details see page
<=>
page 212, New tires or wheels.
Off-Road driving?
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. Also refer to
<=>page 177.
A WARNING
Always adjust your driving to road and traffic
conditions. Do not let the extra safety afford­
ed by all-wheel drive tempt you into taking
extra risks.
- Although the all-wheel dr ive is very effec­
t ive, always remember that braking capacity
is limited by tire traction. You should there­
fore not drive at excessive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be ­
gin to slide on top of the water (aquap lan­
ing). If this shou ld occur, you will have no
Smart Technology
warning from a sudden increase in engine
speed as with a front-wheel drive vehicle.
Always drive at speeds which are suited to the road conditions -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa­
bility of electrical energy for starting the engine.
If a vehicle with a conventional energy system is
not driven for a long pe riod of time, the battery
is discharged by idling current consumers (e.g.
i mmobil izer). In certain circumstances it can re­
su lt in there being insufficient energy available to
start the engine.
Intelligent energy management in your vehicle
hand les the distribution of electrical energy.
Starting ability is markedly improved and the life
of the battery is extended.
Basically, energy management consists of
bat­
tery diagnosis , idling current management
and
dynamic energy management.
Battery diagnosis
Battery diagnosis continuously determines the
state of the battery . Sensors determine battery
vo lta ge, battery current and battery tempera­
tu re. This determines the current state of charge
and the power of the battery.
Idling current management
Idling current management reduces energy con­
sumption whi le the vehicle is standing. With the
ignition switched off, it contro ls the energy sup­
ply to the various electrical components. Data
from battery diagnosis is considered.
Depending on the battery's state of charge, indi­
vidual consumers are gradually turned off to pre­
vent excessive discharge of the battery and thus
maintain starting capability .
Dynamic energy management
While the vehicle is being driven, dynamic energy
management distr ibutes the energy generated ..,.
175

Smart Technology
according to the needs of the individual compo­
nents. It regulates consumption, so that more
electrical energy is not being used than is being
generated and ensures an opt imal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­
ate the limits of physics. Consider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica­ tor light (•) appears ¢
page 16.
What you should know
The highest priority is given to maintaining start­
ing capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time of
year. Abundant electrica l energy is requ ired, but
only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In th is instance energy is being
consumed but none is being generated.
It is in precisely these situations that you will no­
tice energy management actively regulating the
d istr ibut ion of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks, e lectrical components are
gradually cut back or switched
off. This reduces
energy consumption and maintains starting ca­ pability over a longer period . Some of the con­
ven ience funct ions may not operate, such as the
interior lights or the powe r seat adjustment. The
conven ience functions w ill be available again
when yo u sw itch on the ignition and start the en­
gine.
With the engine turned off
I f you listen to the radio, for example, with the
engine turned
off or use other MMI functions,
the battery is being discha rged .
If starting capability is jeopardized due to energy
consumption, a message appears in the MMI dis­
p la y. The message indicates that the system will
176
be switched off automatically in a moment . If
you wish to continue using the functions, you have to start the eng ine.
With the engine running
Althoug h elec trical energy is generated when the
vehicle is being driven, the battery can become
discharged . This happens mostly when litt le en ­
ergy is being generated and a great dea l con­
sumed and the battery's state of charge is not
optimal.
To bring the energy ba lance back into equilibri­
u m, consumers which require especially large
amounts of energy are temporar ily cut back or
switched
off. Heating systems in part icular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* or the heated rear
window a re not heating, they have been tempo­
rarily cut back or switched
off. These systems w ill
be ava ilable again as soon as the energy ba lance
has been restored.
You will also notice that engine idle speed has
been increased slightly . Thi s is normal and not a
cause for concern. By incr easing eng ine idle
speed the additional energy required is generated
and the battery is cha rged.

Driving and the
environment
Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1,000 kilometers ):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum perm issible road or engine speed.
During and after break-in period
"'Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under
any circumstances.
"'U pshift into the next higher gear
before reach­
ing the red area at the end of the tachometer
scale
c=> page 10.
During the first few hours of driving, the engine's
internal friction is higher than later when all the
moving parts have been broken in. How well this
break-in process is done depends to a considera­
ble extent on the way the vehicle is driven during
the first 1,000 miles (1,500 kilometers).
(D Note
Extremely high engine speeds are automati­
cally reduced. However, these rpm limits are
p rog rammed for an engine wel l run- in, not a
new engine.
@) For the sake of the environment
Do not dr ive with unnecessarily high eng ine
speeds -upshifting early saves fuel, reduces
noise and protects the environment.
Driving and the environment
New tires
If your vehicle is running on new tires, drive very
carefully for the fi rst 350 m iles (500 kilometers)
after fitting .
New tires tend to be slippery and must also
be "broken-in". Be sure to remember this dur­
ing the first
350 miles (500 kilometers).
Brake gently. Avoid following closely behind
other vehicles or other situations that might
require sudden, hard brak ing .
Avoid damaging the
vehicle
When you are d riving on poor roads, or over
curbs, steep ramps, etc., ma ke certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
T his is espec ially true for veh icles with low-s lung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on
roads
Note the following to avoid vehicle damage when
driving through water, for example on f looded
roads:
- The water must not be any higher than the bot­
tom of the vehicle body.
- Do not drive faster than walking speed.
A WARNING
= -
After driving through water, mud, slush, etc.,
the brakes may be s low to take effect because
of wet brake rotors and pads. Dry the brakes
first by braking carefully to restore the full braking effect.
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through

Driving and th e environment
(D Tips
- Check the depth of the water before driving
through it.
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline¢ page 186,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
¢ page 195, 9::?1 Adding engine oil .
~ Never try to push- or tow -start your veh icle.
The cata lytic conve rter is an eff icient "clean-up"
dev ice bu ilt into the exhaust system of the vehi­
cle. The cataly tic converter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The ex clusive use of u nleaded fuel is critically im­
por tant for the life of the catalyt ic converte r and
p roper functioning o f the engine.
A WARNING ,..___ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park o r operate the vehicle in areas
whe re the hot exhaust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exha ust man i-
178
fold, exha ust pipes, catalytic converter or
heat shields. During driv ing, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank fill ing with
le ad·
ed
fue l w ill already ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
¢page 195.
-Do not drive until the fue l tank becomes
completely empty. The engine co uld m isfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lyt ic converter to overheat.
- Do not turn
off the ignition while the vehicle
is moving .
- Do not continue to operate your veh icle un­
der these conditions, as otherwise fuel can
reach the catalytic converter . This could re­
sult in overheating of the conve rter, requ ir­
ing its replacement.
- T o assure efficient operation of the Emission
Cont ro l System:
- Have your vehicle maintained properly and
in accordance with the se rvice recommen­
dations in yo ur Warranty
& Maintenance
booklet.
- Lack of proper maintenance as we ll as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
(® For the sake of the environment
Even when the Emiss ion C ontrol System is op­
e rat ing proper ly, the exhaust gas can have a
sulfur-like exhaust gas sme ll under some op­
erat ing states. This depends on the sulfur
content of the fuel being used. Us ing a d iffe r­
ent brand of fue l may he lp, or fi llin g the tank
wi th lead-free s uper grade gaso line.
