-Only use the rearview camera to assist you if
it shows a good, clear picture. For example,
the image may be affected by the sun shin­
ing into the lens, d irt on the lens, or if there
is a malfunction .
- Use the rearview camera only if the luggage
compartment lid is completely closed . If the
luggage compartment lid is open the orien­
tation lines and blue surfaces are hidden .
Make su re any objects you may have mount­
ed on the luggage compa rtment lid do not
block the rearview camera.
- T he came ra lens enlarges and distorts the
field of v is ion. Th e object appears both al­
tered and inaccurate on the screen.
- In certai n situations, people or objects in
the d isplay appear closer or farthe r away:
- For objects that do not touch the ground,
such as the bumper of a parked vehicle, a
trailer hitch or the rear of a truck . Do not
use the orientation lines in this case .
- If driven from a level surface onto an in­
cline, o r a downward slope.
- If driven toward protrud ing objects.
- If the veh icle is carry ing too much load in
the rear.
- Always read and follow the applicable warn­
ings ¢(!) in General information on
page 143 .
-The orange-colored orientation lines in the
Infotainment display show the vehicle path
based on the steering wheel angle . The

Intelligent Technology
-Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect dr iv in g stab ility and
increase the risk of a collision. condition. Different tire
sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working .

Brake booster
The brake booster amplifies the pressu re yo u ap­
p ly to the brake pedal. It only operates while the
engine is running or when the ignition is switched
on (plug-in hybrid drive*) .
A WARNING
- Only apply the brakes for the purpose of
cleaning the brake system when road and
traff ic conditions permit. You must not en­
danger other road users. This increases the
r isk of an accident .
-
-Never let the vehicle roll while the engine is
stopped because this increases the risk of an
acc ident.
- Depend ing on the veh icle equipment, the
brake pedal may be pulled downward when
the vehicle automatically initiates b rak ing.
- Never place objects in the driver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You wo uld not be able to use the ped­
als if sudden driving or braking mane uvers
were needed, which increases the risk of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se­
curely fastened in the footwe lls.
- T o reduce the risk of injury, do not place
your foot under the brake pedal.
(Llj) Note
-Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving on a long stretch with steep
slopes, reduce your speed and shift to the
next lower gear This makes use of the en­
gine braking effect and relieves the brakes.
If you need to brake add it ionally, brake in
i ntervals and not cont inuously.
Intelligent Technology
(D Tips
- If the brake booster is not working, you
must press the brake pedal with much more
force than normal.
- If you retrofit your vehicle with a front spoi l­
er, wheel covers or simi lar items, make sure
that the air flow to the front wheels is not
interrupted. Otherwise the brake system
can become too hot.
Electromechanical
steering
The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the ve hicle speed.
Indicator lights and messages
• Do not drive vehicle: steering defective
If this indicator light turns on and stays on and
th is message appears, the power steering may
have failed .
Stop the vehicle in a safe location as soon as pos­
s ible. Do
not cont inue driving. See an authorized
Audi dealer or authorized Audi Service Fac ility for
ass istance .
l;r-ij Steering: system fault! You can continue
driving
If the indicator light turns on, the steering wheel
may be more difficult to move or more sensitive
than usual. The steering whee l may also be at an
angle when driving straight.
Drive slowly to an authorized Audi dea ler or au­
thorized Audi Service Facility to have the mal­
function corrected.
(D Tips
If the. or 'Tij indicator light on ly stays on
for a short time, you may continue driving .

Intelligent Technology
All wheel drive (quattro)
Applies to: vehicles with all wheel drive
In oil wheel drive, oil four wheels ore powered.
General information
In all wheel drive, the driving power is divided be­
tween all four wheels. This happens automatical­
ly depending on your driving behavior as well as
the current road conditions. Also see
c:> page 148, Electronic Stabilization Control
(ESC) .
The a ll wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow­
erful and has excellent driving characteristics
both under normal driving conditions and on
snow and ice. Always read and follow safety pre­
cautions
c:> & .
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
oil four wheels in the winter is recommended,
because this will improve the
broking effect.
Snow chains
If there are snow chain laws, snow chains must
also be used on vehicles with all wheel drive
c:> page 346, Snow chains.
Replacing tires
For vehicles with all wheel drive, only whee ls with
the same rolling circumference shou ld be used.
Avoid using tires with different tread depths
c:> page 33 7, 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 a ll wheel drive, adapt
your driv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into taking risks,
152
because this increases the risk of an acci ­
dent.
- The braking ability of your vehicle is limited
to the traction of the whee ls. 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 driv ing at speeds that
are too high . Unlike front wheel drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydrop laning .
Fo r this reason, adapt your speed to the
road conditions to reduce the risk of an acci­
dent.
Energy management
Your vehicle is equipped with an intelligent ener ­
gy management system for distributing electrici­
ty. Thi s significantly improves the starting ability
and increases the vehicle battery life.
(D Tips
-If you drive short distances frequently, the
vehicle battery may not charge enough
whi le driving. As a result, convenience func­
t ions for electrical equipment may be tem­
porarily unavailable.
- The vehicle battery w ill gradually drain if
the vehicle is not driven for long per iods of
t ime, or if electrical equipmen t is used
when the engine is not running. To ensure
that the vehicle can still be started, the
electrical equipment will be reduced or
switched off.
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 ma in purpose of an EDR is to
.,.

u. 00 .-< N l'­ N .-< 0 N > 00
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 re lated 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
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-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, could combine the EDR data with the
type of personally identifying data routinely ac­
quired during a crash invest igation .
To read data recorded by an EDR, special equip­
ment is required, 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 specia l equipment, can read the in­
formation if they have access to the vehicle or the
EDR.
Aud i w ill only access the EDR and/or sim ilar data
or give it to others with the consent of the owner
or lessee or in accordance with applicable law.
States vary in their access/disclosure restrictions
for EDR data, but typically such data can be ac­
cessed/disclosed in the following c ircumstances :
- when the vehicle owner (or lessee if the vehicle
has been leased) agrees; or
- upon the officia l request by the police; or
- up on the order of a court of law or a govern-
ment agency; or
- for the defense of a lawsu it through the judicial
dis covery process.
Intelligent Technology
-Audi may also use the data, once retrieved from
the vehicle under permissib le circumstances, in
an anonymous format.
- for research about vehicle operation and safety
performance or provide the data to a third par­
ty for such research purposes.
Vehicle control modules
Your vehicle is also equipp ed w ith a number of
electronic control modules for various vehicle
systems, such as engine management, emission
control, airbags, and safety belts.
Th ese elect ronic control modules record data
during norma l vehicle operation that may be
needed by trained technicians for diagnostic and
repair purposes. The recording capabi lity 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 with specia l equipment that is di­
rectly connected to the vehicle .
(D Tips
Your vehicle may be equipped w ith Audi 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 Aud i connect is
collected, processed, transmitted, used, and
shared, please see your contract with the
wireless telecommunications provider.

Checking and Filling
Checking and Filling Fuel
Gasoline grade
A pp lies to: ve hicles w ith gasoline engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven with
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gasoline can be found on the official web­
site (www .toptiergas.com).
The individual gasoline grades are differentiated
by
octane ratings. This value is given with (R +M)/
2 equating to AKI or in RON.
The following headings match the corresponding
sticker in the fuel filler door .
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regular/ MIN. RON 91 Regular
Use regular gasoline with minimum 87 AKI/
91 RON
i::>@ .
The max imum eng ine power is only reached if
p rem ium gasol ine 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN. (R
+M)/2 91 / SUPER MIN. RON 95
Using premium gaso line with minimum 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also use regular gasoline 87 AKI/ 91 RON . However
this does reduce th e engine powe r slight ly.
0 Note
- Fillin g the tank just one time with leaded
fuel or other metallic additives will cause
permanent deter iorat ion to the catalytic
converter function.
- When gasoline with an octane rat ing that is
too low is used , h igh speeds or heavy engine
load can lead to engine damage.
314
(D Tips
The vehicle may be filled with fuel that has a
h igher octane rating than what is required by
the eng ine.
Blended gasoline
App lies to : vehicles wi th gaso line e ngi ne
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al ­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- 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 gasoline and ethanol (grain alcohol or
ethyl alcohol)
-Anti-knock index must be 87 AK I or h igher.
- Blend must not conta in more than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend must not contain more than 15% MTBE.
Seasonally adjusted 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 stat ions where the seasonal
adjustment is more lik ely to be made in t ime.
@ Note
- Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plastic and rubber components in the
fuel system.
- Do not u se fue ls that fail to meet the speci-
fied criteria in this chapter.
