,...., -Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, ac­ tivate the parking brake and move the selec­
tor lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre ­
vent the vehicle from "creeping", you must keep your foot on the brake when the en­
gine is running and the selector lever is in D/
5 or R or "tiptronic" mode is selected .
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is running.
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with "tiptronic" .
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system .
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload . An indicator lamp
[ijJ illuminates
and a driver message appears
c> page 126
when the clutch is overloaded .
- If the engine must remain running, never
have any driving position engaged when
checking under the hood.
Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
c> page 220. Otherwise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se-
Automatic transmission
lected. This can cause the transmission to
overheat and can damage it. Activate the
parking brake or press the brake pedal to
prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in N will
damage the transmission because it is not
lubricated under those circumstances.
(!) Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the driver
when driving down decline s.
Hill descent control is activated when the selec­
to r lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
tha t is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical
limitations. It may still be necessary to adjust the
speed with the brakes .
Hill descent control switches off once the decline
levels out or you press the accelerator pedal.
When the speed is set in the cruise control sys­
tem
c> page 95 , hill descen t control is also ac ti­
vated .
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions . Always
be ready to apply the brakes.

using the shift paddles, move the selector lever
to the right out of the D/S position .
The transmissron automatically shifts up or down
before critical engine speed is reached.
The transmission only allows manual shifting
when the engine speed is within the permit ted
range.
(D Tips
- When you shift into the next lower gear, the
t ransm ission will downshift only when there
is no possibili ty of
over-revving the engine.
- When the kick-down comes on, the trans­
mission will shift down to a lower gear, de­
pending on vehicle and engine speeds.
- Tiptr onic is inoperat ive when the transmis­
sion is in the fail-safe mode.
- Hybrid drive*: elect ric driving is not possible
in t iptronic mode .
Kick-down
Kick-down enables maximum acceleration .
When you depress the accelerator pedal beyond
the resistance point, the automat ic transmission
downshifts into a lower gear, depending on vehi­
cle speed and engine speed. T he upsh ift into the
next higher gear takes place once the maximum
specified eng ine speed is reached.
A.::!!. ARNING
-Please note that the drive wheels can spin if
kick-down is used on a smooth slippery road -
there is a risk of skidd ing.

recorded by the Event
Data Recorder and
vehicle control modules
E ve nt Dat a Record er
This vehicle is equipped wi th 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 period of
time, typically 30 seconds or less. The EDR in this
ve hicle is designed to reco rd such data as:
- How various systems in your vehicle were oper­
at ing;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the dr iver 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 c ircumstances in which crashes and in ­
juries occur. NOTE: EDR data are recorded by your
veh icle only if a non-trivia l 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 . H owever, other parties, such as law en­
forcement, cou ld combine the EDR data w ith the
type of personally identifying data routine ly ac­
quired during a crash investigation.
To read data recorded by an EDR, specia l equip­
ment is req uired, a nd access to the ve hicle or the
E DR is needed. In add it ion to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the specia l 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 ED Rs insta lled in a vehi­
cle for the express purpose of retrieving data af-
Intellig ent Technology
ter an accident or crash event without the own­
er 's consent.
Audi will not ac cess the EDR and/or sim ilar data
o r give it to others -
- unless the vehicle owne r (or lessee if the vehi­
cle has been leased) agrees; o r
- 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 jud ic ial
discovery process.
- Aud i may a lso use the data for research about
veh icle operation and safety performance or
prov ide the data to a third party for research
purposes without identify ing the specific veh i­
cle or info rmat io n about the ident ity of its own­
er or lessee and only afte r the reco rded veh icle
data has been accessed.
Vehicle control modules
Your vehicle is also equ ipped w ith a number of
electronic control modules for va rious vehicle
systems, such as engine management, emiss io n
contro l, airbags , and s afety be lts .
These electronic control modules record data dur ing norma l vehicle operation that may be
needed by trained tech nicians for diagnost ic and
r epa ir purposes. The re cording capab il ity of these
modules is lim ited to data (no sound is record­
ed). Only a sma ll amount of data is actua lly 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
vehicle speed, direction, or braking, as well as re­
straint system use and performance in the event
of a crash . Stored data can also on ly be read a nd
down loaded w ith specia l equipment that is d i­
rectly connected to the vehicle.
(D Tips
Your vehicle may be equipped w ith Aud i con­
nect. Your use of certain Aud i connect fea­
tures requi res wire less serv ices that are pro­
v ided by a third party wireless telecomm uni­
cations provi der. For de tails regarding how in­

brake. This may cause the brakes to over­
heat, premature wear and increased stop­
ping distance.
- Under certain climatic and operating condi­
tions such as passing through water, driving
in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­ duced . In winter, ice can accumulate on the
brake 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 without using your
brakes can also affect braking efficiency.
Clean off accumulated salt coating from
brake discs and pads with a few carefu l
brake app lications .
-If you damage the front spoiler, or if you in­
stall a different 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 circuit will impair the
braking capability resulting in an increased
stopping distance. Avoid driving the vehicle and have it towed to the nearest author ized
Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assista nee.
Electromechanical power
assist, Dynamic steering
The electromechanical power assist helps the
driver when steering.
Power steering adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defective! Do not drive vehicle!
194 If
this indicator light turns on and stays on and
this message appears, the power steering may
have failed.
Stop the vehicle in a safe location as soon as pos­
sible. Do
not continue driving . See your author­
ized Audi dealer or other qualified repair facility
for ass istance .
'-r, ij Dynamic steering: System fault! You can
continue driving
If the indicator l ight turns on and the message
appears, the steering may be more difficult to
move or more sensitive than usual. The steering
may also be at an angle when driving straight.
Drive slowly to your authorized Audi dealer or
qualified workshop to have the malfunct ion cor­
rected.
1 :r- ij Dynamic steering: Initializing
Audi drive select* : if the indicator light blinks and
the driver message appears, the dynamic steer­ i ng* is reinitial ized. After start ing the engine, the
steering wheel will move slightly . Re-initial iza­
tion might be necessary if the steering wheel was
moved hard to the left and right while the vehicle
was not moving. The display turns off if the initi­
alization was successful.

Driving with your
quattro
With all-wheel drive, all four wheels are driven .
General information
With all-wheel drive, power is distributed to all
four wheels. This happens automatically depend­
ing on your driving style and the road conditions
at the time. See also

The all-wheel drive concept is designed for high
engine power. Your ve hicle is exceptionally pow­
erful and has excellent driving characterist ics
both under norma l dr iving condit ions and on
snow and ice. Always read and follow safety pre ­
cautions ¢.&. .
Winter tires
When driving in the w inter, your vehicle with a ll­
wheel drive has an advantage, even with regular
tires. In winter road conditions it may be adv isa­
b le to mount w inter t ires (or all-season tires) for
i mproved driveab ility and brak ing : these tires
must be mounted on
all four wheel s. See a lso
¢ page 249, Winter tires.
Tire chains
Where tire chains are manda tory on certain
roads, this normally also applies to vehicles w ith
a ll-wheel drive¢ page 249 , Snow chains.
Replacing wheel s/tires
Veh icles with all -whee l dr ive must always have
tires of the same s ize. A lso avo id tires with differ­
ent tread depths . For detai ls see page
¢ page 241, New tires or wheels.
A WARNING
Always adjust you r driving to road and t raff ic
conditions. Do not let the extra safety affo rd­
ed by all-wheel drive te mpt you into tak ing
extra risks.
- Alt hough the all-whee l dr ive is very effec­
t ive, always remember th at br akin g ca pac ity
is limited by tire traction. Yo u should t here­
fore not d rive at excess ive speeds on icy or
slippery road surfaces.
- On wet road surfaces, be caref ul not to drive
too fast because the front wheels co uld be­
gin to slide on top of the water (a quaplan­
ing). If this shou ld occu r, you w ill have no
warning from a sudden increase in eng ine
speed as with a front -whee l dr ive vehicle.
Intellig ent Technology
Always d rive at speeds which are suited to
the road conditions -risk of c rash.
Energy management
Starting ability is optimized
E nergy 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 dr iven fo r a long pe riod of time, the ba ttery is
discharged by id ling curre nt cons umers (e.g. im­
mobili ze r). In ce rtain circumstances i t can resu lt
i n t he re being insuffi cient energy av ailabl e to
st ar t the eng ine.
Intellige nt ene rgy manageme nt in yo ur vehicle
hand les the d ist ribution of electrical e nergy.
St art ing abil ity is m arkedly improved and the life
of the ba ttery is ex tende d.
Bas ica lly, energy management co nsists of
bat­
tery diagnosis , idling current management
and
dynami c energy management .
Battery diagnosis
Battery d iagnosis continuously determ ines the
state of the battery . Sensors de termine battery
vo ltage, battery curren t and batte ry tempera­
tu re . This determines t he cur rent state of c harge
and the power of t he ba ttery.
Idling current management
Idli ng cur rent management reduces energy con ­
s u mption wh ile the vehicle is standing . With the
ignition switched off , it contro ls the energy sup­
ply to the vario us elec trical componen ts. Data
fr om b attery diagnosis is co nsidere d.
Depend ing on the ba tte ry's s ta te of charge, indi­
v idual consumers are gradually turned off to pre­
ven t ex cess ive disc ha rge of t he battery and thus
m ain ta in starting c ap abili ty.
Dynamic energy management
While the vehicle is being driven, dynam ic e nergy
manageme nt dis trib utes the energy generated
according to the needs of the ind ividual compo-
nents.
It regula tes consu mption, so that more ..,.

Intelligent Technology
electrical energy is not being used than is being
generated and ensures an optimal 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
r=:; page 33.
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 electrical energy is required, but only a little is generated. It is also critical if the
engine is not running and electrical components
are turned on. In this 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
distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period of
several days or weeks, electrical 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
venience functions may not operate, such as the interior lights or the power seat adjustment . The
convenience functions will be available again
when you switch on the ignition and start the en­
gine.
With the engine turned off
If you listen to the radio, for example, with the
engine turned off or use other MMI" functions,
the battery is being discharged .
If starting capability is jeopardized due to energy
consumption, a message appears in the radio or MMI* display . The message indicates that the
system will be switched off automat ical ly in a
196
moment. If you wish to continue using the func­
tions, you have to start the engine .
With the engine running
Although electrical energy is generated when the
vehicle is being driven, the battery can become
discharged. This happens mostly when little en­
ergy is being generated and a great deal con­
sumed and the battery's state of charge is not
optimal.
To bring the energy balance back into equilibri­
um, consumers which require especially large
amounts of energy are temporarily cut back or
switched off. Heating systems in particular re­
quire a great deal of energy. If you notice, for ex­
ample, that the heated seats* or the heated rear
window are not heating, they have been tempo ­
rarily cut back or switched off . These systems will
be available again as soon as the energy balance
has been restored.
You will also notice that engine idle speed has
been increased slightly . This is normal and not a
cause for concern. By increasing engine idle
speed the additional energy required is generat­
ed and the battery is charged.

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 kilometer s):
"' 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 pe rm issib le road or engine speed .
During and after break-in pe riod
"' 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 c ircumstances.

Driving and the envir onment
New tires
If your vehicle is runn ing on new tires, d rive very
car efu lly fo r the firs t 35 0 miles (500 kilometers)
a ft er fit ting.
WARNING
New tires tend to be slippe ry and must a lso
be "bro ken-in". Be sure to remembe r th is dur­
i ng the fi rst 350 m iles (500 kilometers).
Brake gent ly. Avoid following closely behind
other vehicles or other s ituations that m ight
r equire sudden, hard b raking.
Catalytic converter
Applies to vehicles: wit h gasoli ne e ngi ne
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmen tally sound manner.
"' Always use lead-free gasoli ne c> page 212,
Gasoline .
"' Never run t he tank down all the way to empty.
"'N ever put too much mo to r oil in yo ur eng ine

T he cat alyt ic co nverter is an efficie nt "cle an-up"
device built into the exhau st sys tem o f the ve hi­
cl e. T he catalyt ic converte r burns many of the
po llutants in the exhaust gas before they are re ­

A WARNING
=
The temperat ure o f the exhaust system is
hi gh, both when driv ing and after stopping
the eng ine.
-
- Never touch the exhaus t tail pipes once they
have become hot. This cou ld res ult in burns.
- Do not park or operate the vehicle in a reas
where the hot exhaust system may come in
contact w ith dry g rass, brush, fuel sp ill o r
other mate rial wh ich can ca use a fire.
197

Driving and th e en vironm ent
- Do not apply additional undercoating or
rustproofing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or heat sh ields . During dr iv ing, the substance
used for undercoating could overheat and
cause a fire .
{U) Note
-Be aware that just one tank filling with
leaded fuel will already seriously degrade
the performance of the catalytic co nverter .
- Do not exceed the correct engine oil level
c:>page224 .
-Do not drive until the fuel tank becomes
completely empty . The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and this could cause the
catalytic converte r to overheat.
- Do not turn off the ignition while the vehicle
. . 1s moving.
- Do not continue to operate your vehicle un ­
der these cond itions, as otherwise fuel can
r each the catalytic converte r. This could re­
su lt in overheating of the converter, requir­
i ng its replacement .
- To assure efficient operation of the Emis ­
s ion Control System:
- Have your vehicle maintained properly and in accordance with the service recommen­
dations in your Warranty
& Maintenance
booklet .
- Lack of proper maintenance as well as im­
proper use of the vehicle will impair the
function of the em ission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erat ing properly, the exhaust gas can have a
sulfur-like exhaust gas smell under some op­
erat ing states . This depends on the su lfur
content of the fuel be ing used. Using a differ­
ent brand of fue l may he lp, or filling the tank
with lead-free super grade gasoline.
