The all-wheel drive system dist ributes the d riving
power var iably to the front and rear axle. It works
together with selective whee l torque cont rol,
which activates when driving through curves
c:> page 146. With the sport differentia l*, power
d istribution to the rear wheels is variable and can
be adjusted using the dr ive select
c:> page 134.
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 fo llow safety pre ­
cautions
c:> .&. .
Winter t ires
By us ing all wheel drive, yo ur vehicle has good
forward motion with standard tires in w inte r con­
d itions. However, using winter or all season tires
on
all four wheels in the winter is recommended ,
because this will improve the
braking effec t.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 350, Snow chains .
Replacing tire s
For vehicles with all whee l drive, only whee ls with
the same ro lling circumference s hou ld be used.
Avoid using tires w ith different tread depths
c:> page 341, New tires or wheels.
Offroad vehicle?
The ground clearance is too low on some mode ls
to drive on rough terrain. Therefore, avoid off­ road trips.
A WARNING
-Also, in vehicles with a ll w heel d rive, adapt
your dr iv ing style to the current road and
t raff ic conditions . Do not let the increased
safety provided tempt you into tak ing risks,
because t his increases the r is k of an acci­
dent .
Intellig ent Technology
- The braking ab ility o f 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
h igh speed whe n the road is sli ppery, be­
cause this i ncreases the risk of an accident.
- No te that o n wet streets, the fron t wheels
can "hydrop la ne" if dr iv ing at speeds that
are too high. Unlik e front wheel d rive
veh icles, the engine does not rev h ig her sud­
denly when the vehicle begins hydrop laning.

road conditions to re duce the risk of an acci­
dent .
Energy management
The starting ability is optimized
The energy management system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine .
When a vehicle with a conventional energy sys­
tem is not drive n for a long time, the ve hicle bat­
te ry is d rained by equipment (for example, t he
immob ilizer). In certa in circ ums tances , there
c ou ld m ay no t be eno ugh e nergy to start the en­
gine.
You r vehicle is equi pped with an in tell igent ener­
gy manageme nt system fo r dist ributing electrici­
ty. This sig nifican tly improves the start ing ability
and in cre ase s t he vehicle battery life.
The ene rgy ma nagement system Is made up of
battery diagnosi s, idling current management ,
and dynamic energy management .
Battery diagnosis
The battery diagnos is determines the vehicle bat­
te ry c harge level. The sensors determine the bat ­
te ry vo ltage, the batte ry cu rrent, and the batte ry
temperat ure. The current c ha rge level and t he
perfo rman ce of the vehicle battery a re de ter-
mine d base d on this.

Intelligent Technology
Idling current management
The idling c urrent management dec reases the
energy used w hile pa rked. With the engine
sw itched off, it manages the energy distribution
to the different elect rical components . Data from
the battery diagnosis is taken into account for
this .
Depending on the vehicle battery charge level,
e lectrical 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 manag em ent
W hil e driving, dynamic energy management dis ­
tr ibutes the appropriate amount of energy to the
electrical equipment. It controls the battery
charge level so that the amount of energy is not
greater than the amount being generated in or­
der to mai nta in a n optimal vehicle battery charge
level.
(D Tips
- Energy management cannot overcome the
l aws of phys ics . Note that the charge leve l
and leng th of the vehicle battery life a re
li mi ted .
- When the starting ability is endanger ed, the
(•) ind icator 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 dr iv ing short d istances, dur ing c ity dr iv ing,
and at cold times of the year . A lot of energy is
used but little is gene rated . It is a lso cri tical
wh en the engine is not runn ing but e lectr ica l
e qui pment is swi tc h ed o n. In this case, energy is
u sed bu t none is ge nera te d.
In s ituatio ns l ike this, energy management will
actively regu late the d ist ribu tion of ene rgy.
Long pe riods without use
If you do not drive your vehicle for several days or
weeks, electrica l equipment is gradually scaled
back or swi tched off . This reduces energy use and
152 ensures
the vehicle will be ab le to s tart a fter long
periods of time. Some conven ience f unctions,
such as interior lig hting or power seat ad just ­
ment, may not be avai lab le under ce rtain circum­
stances. These conven ience functions will be
available again once you switch the ignit ion on
and sta rt the eng ine.
With the engine switched off
The vehicle battery will drain if you use Infotain ­
ment functions such as listening to the radio
whi le the engine is switched off.
If the vehicle's ability to start may be impaired by
the energy use, a message will appear i n the In­
fota inment system display. The message indi­
cates that the system will switc h off automatical­
l y soon. If yo u wou ld like to continue using the
funct io ns, you must s tart the engine .
With the engine running
Although electr ica l energy is generated w hile
driv ing, the veh icle battery can d ra in. This can
happe n if litt le ene rgy is generated but much is
used, and the charge level of the vehicle battery
is not optimal.
To resto re t he ba lance of energy, components
that require large amounts of energy are tempo­ rarily scaled back or sw itched off. Heat ing sys ­
te ms in pa rticula r r equir e a great deal of e nergy .
I f you notice, fo r example, t hat the seat heati ng*
o r r ear window defogger is not wor king, then it
h as been tempor arily reduce d or switched off.
These sys tems are avai lab le aga in as soon as t he
energy supp ly has been restored.
I n add it ion, yo u may notice tha t the idle speed
h as slig htly incre ase d. Tha t is normal and no
ca use for concer n. By in creasing the idling spee d,
the addit io na l required energy will be gene rated
and t he vehicle battery w ill 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
veh icle is designed to record 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 driver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can he lp prov ide 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. Howeve r, 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, specia l 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 specia l 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 insta lled in a vehi ­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own­ er's consent.
Intelligent Technology
Audi will not access the EDR and/or simi la r data
or give it to others -
- unless the vehicl e 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 jud ic ial
discovery process.
- Aud i may also use the data for research about
veh icle operation and safety performance or
prov ide the data to a th ird party for research
purposes without ide ntify ing the specific vehi­
cle or information about the identity of its own­
er or lessee and only after the reco rded vehicle
data has been accessed.
Vehicle control modules
Your vehicle is also equipped w ith a number of
electronic control modules for various vehicle
systems, such as engine management, emiss ion
contro l, airbags, and safety be lts.
T hese elect ronic contro l modu les record data
dur ing normal vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capab ility 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
down loaded w it h special equipment that is di­
rectly connected to the vehicle .
(D Tips
Your vehicle may be equipped w ith Aud i con­
nect. Your use of certain Audi connect fea­
tures requires wire less services that are pro­
vided by a third party wireless telecommuni ­
cations provider . For details regarding how in­
formation obtained through Audi connect is
collected, processed, transmitted, used, and
shared, please see your contract with the
wireless telecommunications provider and the
IJJJ,-

nation, only when the vehicle is stationary . Al ­
ways be prepared to stop operating the Infotain­
ment system in the interest of your safety and
the safety of other road users.
A WARNING
Only use the Infotainment system when traf­
fic conditions permit and always in a way that
allows you to maintain complete control over
your vehicle.
@ Tips
Certain functions are not available while driv­
ing .
Introduction
The Multi Media Interface, or MMI for short,
combin es various systems for communication,
