Media

Media
General information
There are various media drives and connections
available in the MMI. For example, you can play
media files using the SD card reader or connect
your mobile devices 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 available in the market.
However, there may be cases where individual de-
vices or media and audio/video files may not be
recognized, 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 AG is
not responsible for damaged or lost files and me-
dia.
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.

could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of
hydroplaning.

To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> If the removed wheel does not fit in the spare
wheel well, store it securely in the luggage
compartment > page 77.
> Check the tire pressure on the installed wheel
as soon as possible.
> Correct the tire pressure and store it in the MMI
=> page 262.

ee eeue lela)
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. Au-
di 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
— 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.

@) Note
—Ifthe |_E| indicator light turns on, there is a
fault in the cooling circuit. The vehicle must
not be towed. The drive system can be se-
verely damaged.
— 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.
— Towing must not be used to charge the
high-voltage battery (recuperation), be-
cause this could result in major damages to
the tow vehicle or the vehicle being towed. >
