Media
General information
There may be different media drives and connec-
tions available depending on the vehicle equip-
ment. For example, you can play media files us-
ing
the SD card reader or connect your mobile de-
vices to the Audi music interface and operate
them through the MMI.
Media and format restrictions: the MMI (includ-
ing the SD card reader and the USB storage de-
vice connection) was tested with a variety of
products and media on the market. However,
there may be cases where individual devices or
media and audio/video files may not be recog-
nized, may play only with restrictions, or may not
play at all.
Restricted functionality: reset the Media to the
factory default settings if functionality is restrict-
ed.
Digital Rights Management: please note that
the audio/video files are subject to copyright pro-
tection.
The media drives do not play files that are pro-
tected by DRM and are identified with the symbol
&.
Data security: never store important data on SD
cards, CDs/DVDs, or mobile devices. Audi is not
responsible for damaged or lost files and media.
Loading times: the more files/folders/playlists
there are on a storage medium, the longer it will
take to load. To reduce the amount of time it
takes the audio/video files to load, use a storage
medium that only contains audio/video files, and
create subfolders (for example, for each artist or
album).
Additional information: when playing, audio
files are automatically displayed with any addi-
tional information that is stored (such as the ar-
tist, track and album cover). If this information is
not available on the storage medium, the MMI
will check the Gracenote metadata database.
However, in some cases, the additional informa-
tion may not be displayed.
CG) Note
Read the information about Audi connect, and
be sure to note the connectivity costs section
=@ in General information on page 174.

The SD card reader is in the storage compartment
under the front center armrest.
Inserting the SD card
> The angled corner of the SD card must face to-
ward the right front side when being inserted.
» Slide the SD card into the card reader slot until
the SD card clicks into place.
The SD card reader is accessed and operated
through the MMI => page 209.
@) Note
— Only use one-piece SD cards. If adapter
cards (SD cards with more than one piece)
are used, the card could fall out of the
adapter when driving because of vibrations.
Individual pieces could then become stuck
in the drive and impair the functionality.
—To reduce the risk of damaging drives and
data carriers, always keep data carriers ina
sleeve and never expose them to direct sun-
light.
DVD drive
Applies to: vehicles with a DVD drive
The functionality of individual storage mediums
may be limited due to the variety of blank CDs/
DVDs available and the various capacities. Audio

Message
B Warning! Hood is not locked. Stop vehicle
and check the lock
The hood latch is not locked correctly. Stop im-
mediately and close the hood.

ZX WARNING
— Never open the hood when there is steam or
coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— For safety reasons, the hood must always be
latched securely while driving. Because of
this, always check the hood after closing it
to make sure it is latched correctly. The hood
is latched if the front corners cannot be lift-
ed.
— If you notice that the hood is not latched
while you are driving, stop immediately and
close it, because driving when the hood is
not latched increases the risk of an accident.

Checking and Filling


— You must close the cap on the oil filler open-
ing correctly so that oil does not leak out on-
to the hot engine and exhaust system when
the engine is running, because this is a fire
hazard.
— Always clean skin thoroughly if it comes into
contact with engine oil.
—
Engine oil is poisonous and must be kept out
of reach of children.
— Store the engine oil securely in the original
container.


©) Note
— The New Vehicle Limited Warranty does not
cover damage or malfunctions if the recom-
mended intended use of the vehicle and
maintenance measures listed in the Audi
Owner's Manual and the Warranty & Main-
tenance Booklet were not followed.
— Only use high-grade engine oil that explicit-
ly meets the Audi oil quality standard for
your vehicle. Using another oil may cause
severe vehicle damage.
— Do not mix any additives with the engine oil.
Additives may cause engine damage that is
not covered by your New Vehicle Limited
Warranty.
@ For the sake of the environment
— Oil should never enter the sewer system or
come into contact with the ground.
— Follow the legal regulations in the country
where you are located when disposing of
empty oil containers.
Changing engine oil
We recommend having the oil changed at an au-
thorized Audi dealer or authorized Audi Service
Facility.
Follow the safety precautions > page 227, Gener-
al information.
The engine oil must be changed at the intervals
specified in the Warranty & Maintenance Book-
let. This is very important because the lubrication
function of the oil gradually declines during regu-
lar vehicle operation.
The engine oil should be changed more frequent-
ly under certain circumstances. Have the oil
changed more frequently if you often drive short
distances, your vehicle is predominantly in stop-
and-go traffic situations, is in very dusty environ-
ments, or is operated for long periods of time in
temperatures below zero.
Cleansing additives in the oil make fresh oil ap-
pear darker after the engine has run briefly. This
is normal and no reason to change the engine oil
more frequently than recommended.
Because correctly disposing of engine oil is diffi-
cult and special tools and technical knowledge
are needed for an oil change, having your engine
oil changed by an authorized Audi dealer or au-
thorized Audi Service Facility is recommended.
If you change the engine oil yourself, please note
the following important information:

ZA\ WARNING
If you change the engine oil on the vehicle
yourself, the following precautions must be
followed:
— Wear protective eyewear.
— Due to the risk of scalding, allow the engine
to cool down sufficiently.
— Maintain enough distance when you are re-
moving the oil drain plug. While doing this,
keep your forearm parallel to the ground to
reduce the risk of hot oil dripping down your
arm.
— Drain the oil into a container designed for
this purpose that is large enough to hold the
full amount of oil in your engine.
— Engine oil is poisonous. Always store out of
reach of children.
— Prolonged contact of used engine oil with
the skin may cause skin damage. Always
wash oil off immediately with soap and wa-


ter to protect your skin.

@) Note
Do not mix any additives with the engine oil.
Additives may cause engine damage that is
not covered by your New Vehicle Limited War-
ranty.

Towing
General information
You should only perform the steps that follow if
you have the necessary tools and technical ex-
pertise.
Towing requires a certain amount of practice.
Audi recommends contacting a towing company
to have the vehicle transported.
You should only have your vehicle towed by an-
other vehicle when disabled in exceptional cir-
cumstances. Inexperienced drivers should not
tow.
Notes on towing
When the engine is stopped, the transmission
will not be sufficiently lubricated if traveling at
high speeds and long distances:
— The maximum permitted towing speed is 30
mph (50 km/h).
— The maximum permitted towing distance is 30
miles (50 km).
Additional information on towing with a tow
truck
The vehicle may only be towed with the front axle
raised. Do not wrap any chains or cables around
the brake lines.
Tow bar and towing cable
The vehicle can be towed with a tow bar or tow-
ing cable. Both drivers should be familiar with
the special considerations when towing, especial-
ly when using a towing cable.
Always make sure the traction force does not ex-
ceed the permitted level and there are no shock
loading conditions. There is always the risk of the
coupling becoming overloaded when driving off-
road.
For the most safety and security, drive with a tow
bar. You should use a towing cable only if a tow
bar is not available. Use a towing cable made of
synthetic elastic cable similar elastic material.

ZA WARNING
— Towing highly increases the risk of an acci-
dent, for example from colliding with the
towing vehicle.
—To reduce the risk of an accident, do not al-
low anyone to remain inside the vehicle
when it is being transported by a tow truck
or a special transporter.

CG) Note
— If normal towing is not possible, for exam-
ple if the transmission is faulty or if the
towing distance is greater than 30 miles
(50 km), then transport the vehicle on a
special carrier.
— If the vehicle is towed by a tow truck at the
axle that is not permitted, this can cause se-
vere damage to the transmission.
— The vehicle must not be tow started for
technical reasons.
(i) Tips
— If the power supply is interrupted, then it
will not be possible to move the selector
lever out of the "P" position. The parking
