Intelligent Technology
CJ) Note
- Neve r let the brakes "rub" by pressing the
pedal light ly when bra king is not actually
necessary. This causes the brakes to over­
heat and increases braking d istance and
causes wear .
- Before driv ing downhill a long distance on a
steep hi ll, decrease your speed and select a
l ower gear. This makes use of the engine
b raking effect and re lieves the brakes . If
you need to b rake additionally , brake in in­
te rvals and n ot co nti nu ously .
(J) Tips
-If the b rake booster is no t wo rking, you
must press the brake pedal with much more
fo rce th an norma l.
- If you re trofit you r vehicle with a fron t spoil­
e r, whee l cove rs o r similar items, ma ke sure
th at t he ai r flow to the fron t wheels is not
i nte rr upt ed . Ot he rw ise the bra ke sys tem
ca n become too hot.

ALL-wheel drive (quattro)
General information
In all whee l drive, the dr iv ing power is dis trib ut­
ed betwee n all fou r whee ls w hen needed . This
happe ns automatically depending on your driving
behavior as we ll as the c urrent road con ditions.
A lso see
c:;, page 151, Electronic stabili zation
control (ESC) .
The all-whee l dr ive system distr ibutes the dr iving
power va riably to the front and rear axle. It works
together with selective wheel torq ue control,
which act ivates when dr iv ing through c urves
q page 151. With the sport d ifferent ial*, power
distribution to the rear wheels is var iable and can
be adjusted using the drive select

The all wheel drive concept is designed for high
engine power . Your vehicle is except iona lly pow­
erfu l and has excellent driving characteristics

snow and ice. Always read and follow safety
precautions¢.&. .
Winter tires
By using all wheel drive, your vehicle has good
forward motion with standard tires in winter con­
ditions. However, using winter or all season tires
on
all four wheels in the winter is recommended,
because this will improve the
braking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
¢ page 358, Snow chains.
Replacing tires
For vehicles with all wheel drive, only wheels with
the same rolling circumference should be used.
Avoid using tires with different tread depths
¢ page 348, New tires or wheels.
Offroad vehicle?
Your Audi is not an offroad vehicle -there is not
enough ground clearance. For this reason, avoid
difficult terrain .
A WARNING
-Also, in vehicles with all wheel drive, adapt
your driving style to the current road and
traffic conditions. Do not let the increased
safety provided tempt you into taking risks,
because this increases the risk of an acci­
dent .
- The braking ability of your vehicle is limited
to the traction of the wheels. In this way, it
is not different from a two wheel drive 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 wheel 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 acci­
dent.
Intelligent Technology
Energy management
The starting ability is optimized
T he energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engtne.
When a vehicle with a conventional energy sys­
tem is not driven for a long time, the vehicle bat­
tery is drained by equipment (for example, the
immobilizer). In certain circumstances , there
could may not be enough energy to start the en­
gine.
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty. This significantly improves the starting ability
and increases the vehicle battery life.
The energy management system Is made up of
battery diagnosis, idling current management,
and dynamic energy management.
Battery diagnosis
The battery diagnosis determines the vehicle bat­
tery charge level. The sensors determine the bat­
tery voltage, the battery current, and the battery
temperature. The current charge level and the
performance of the vehicle battery are deter­
mined based on this.
Idling current management
The idling current management decreases the
energy used while parked. With the engine
switched off, it manages the energy distribution
to the different electrical components . Data from
the battery diagnosis is taken into account for
this.
Depending on the vehicle battery charge level,
electrical equipment is switched off one item af­
ter the other to prevent the vehicle battery from draining and to maintain the starting ability.
Dynamic energy management
While driving, dynamic energy management dis­
tributes the appropriate amount of energy to the
electrical equipment.
It controls the battery
charge level so that the amount of energy is not
..,.
155

Intelligent Technology
greater than the amount being generated in or­
der to maintain an optimal vehicle battery charge
level.
(D Tips
- Energy management cannot overcome the laws of physics. Note that the charge level
and length of the vehicle battery life are
limited.
- When the starting ability is endangered, the
(•j indicator light turns on ¢ page 30.
What you should know
Maintaining the starting ability is the highest
priority.
A lot of stress is placed on the vehicle battery
when driving short distances, during city driving,
and at cold times of the year. A lot of energy is
used but little is generated. It is also critical
when the engine is not running but electrical
equipment is switched on. In this case, energy is used but none is generated .
In situations like this, energy management will
actively regulate the distribution of energy.
Long periods without use
If you do not drive your vehicle for several days or
weeks, electrical equipment is gradually scaled
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of time. Some convenience functions,
such as interior lighting or power seat adjust­
ment, may not be available under certain circum­
stances . These convenience functions will be
available again once you switch the ignition on
and start the engine.
With the engine switched off
The vehicle battery will drain if you use Infotain ­
ment functions such as listening to the radio
while the engine is switched off .
If the vehicle's ability to start may be impaired by
the energy use, a message will appear in the In­
fotainment system display. The message indi­
cates that the system will switch off automatical-
156
ly soon. If you would like to continue using the
functions, you must start the engine.
With the engine running
Although electrical energy is generated while
driving , the vehicle battery can drain. This can
happen if little energy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To restore the balance of energy, components
that require large amounts of energy are tempo­
rarily scaled back or switched off . Heating sys­
tems in particular require a great deal of energy. If you notice, for example, that the seat heating*
or rear window defogger is not working, then it
has been temporarily reduced or switched off.
T hese systems are available again as soon as the
energy supply has been restored.
In addition, you may notice that the idle speed has slightly increased. That is normal and no
cause for concern . By increasing the idling speed,
the additional required energy will be generated
and the vehicle battery will be charged.
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 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
namics and safety systems for a short period 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 help 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 required, and access to the vehicle or the
EDR 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 retrieval or down­ loading of data stored by EDRs 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.
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; or
-for the defense of a lawsuit 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 research
purposes without identifying the specific vehi­
cle or information about the identity of its own­
er or lessee and only after the recorded vehicle
data has been accessed.
Vehicle control modules
<( Your vehicle is also equipped with a number of a,
;::; electronic control modules for various vehicle ,....

a,
Intelligent Technology
These electronic control modules record data
during 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
vehicle speed, direction, or braking, as well as re­
straint 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 wireless telecommuni­
cations provider . For details regarding how in­
formation obtained through Audi connect is

Check ing and F illing
Checking and Filling
Gasoline
Fuel supply
Applies to: vehicles with gaso line engine
Using the right fuel helps keep the environment
clean and prevents engine damage.
F u el r eco mmend ati on
The fuel recommended for your vehicle is unle ad­
e d pr em ium
grade gasoline . Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas .com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the ins ide of the fuel filler flap . This rating
may be specified as AK I or RON .
Your veh icle may also be operated using unlead­
ed regular gasoline with a minimum octane rat ­
ing of 87 AKl/91 RON. However, using 87 AKI/91
RON octane fuel w il l slightly reduce engine pe r­
forma nce.
Us e un leade d gaso lin e onl y. Unleaded gasoline
is availab le throughout the USA , Canada, and in
most European countries . We recommend that
you do not ta ke your vehicle to areas or co unt ries
where un leaded gaso line may not be availab le.
For more information on refueling your vehicle,
see
¢ page 324 .
Octane ra ting
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the Un ited
States and Canada has the following octane rat­
i n gs that ca n usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
322
- Regu la r Grade: 87 - 90 AK I
Explanation of the abbreviations:
AKI = Anti Knock Index = (R +M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON = Motor Octane Number.
{[) Note
- Do not use a ny fue l w ith o ctane ratings low­
er than 87 AKI or 91 RON othe rw ise expen­
sive engine damage wi ll occur .
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalyt ic converter and its ability to
control exhaust emissions .
Blended gasoline
Applies to: vehicles with gasoline engine
Use of gaso lin e conta ining alcoho l or MTBE
(meth yl tertia ry butyl ether )
You may use unleaded gasoline blended with al­
cohol or MTB E (commonly referred to as oxygen ­
ates) if the blended m ixture meets the follow ing
criteria:
Blend of g asoline methanol (wood alcohol o r
m eth yl alcoho l)
-Anti -knock index must be 87 AKI or h igher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co -solvents.
Blend of ga soline and ethanol (grain alcohol or
ethyl alc ohol )
- Anti-knock index must be 87 AKI or h igher .
- Blend must not conta in more than 15% etha-
nol.
Blend of gas oline and M TBE
- Anti-knock index must be 87 AK I or h igher .
- Blend must contain not mo re than 1S% MTB E.
S easonall y adjust ed gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you

fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time .
(D Note
-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system.
-Do not use fuels that fai l to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
-Do not use fuel for which the contents can­
not be identif ied.
-Fuel system damage and performance prob­
l ems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
-If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . Al ­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Check ing and Filling
After an extended period o f using inadeq uate
fuels, bui lt-up ca rbon deposits can rob your en­
gine of peak performance.
(D Note
- Damage or malfunction d ue to poor f uel
quality is no t covered by the Audi New Veh i­
cle Lim ited Warranty .
- Do not add af termarket fuel addi tive prod­
u cts to your fue l tank.
Diesel fuel
Applies to: vehicles with diesel engine
Always use U LSD (Ult ra Low Sulfur Diesel) No. 2.
T he ULSD No. 2 meets the AS TM 0975.
D iesel fuel w ith concentrations of b iod iesel h igh­
er than 5
% such as Bl 1, B20 or B100 are st rict ly

Service station fuel pumps are labeled with the
cor rect fuel i nformation for easy recogn ition by
the user. If the d iesel fue l pump is not labeled
as k t he station operator wha t fuel is being dis­
pensed before fill ing up your vehi cle.
U LSD No . 2 may not be ava ilable outside the USA
and Canada. Be su re to check befo re t raveling to
othe r countr ies.
ULSD No . 2 can become thicker in very cold tem­
peratures, and th is can impa ir the engine's start­
ing and runn ing . Depend ing o n the season, gas
stations provide ULS D No. 2 that flows be tte r in
cold te mpe ra tures so that you can conti nue ope r­
at ing your vehicle as usual.
(D Note
- Yo ur vehicle's diese l eng ine w as designed
