Media
General information
There may be different media sources and con-
nections available depending on the vehicle
equipment. For example, you can play media files
using a connected USB drive or connect your mo-
bile devices to the Audi music interface and oper-
ate them through the MMI.
Media and format restrictions: the MMI (includ-
ing the USB storage device connection) was test-
ed with a variety of products and media on the
market. However, there may be cases where indi-
vidual devices or media and audio/video files may
not be recognized, may play only with restric-
tions, or may not play at all.
Restricted functionality: reset the MMI to the
factory default settings if functionality is restrict-
ed > page 213.
Digital Rights Management: please note that
the
audio/video files are subject to copyright pro-
tection.
Files that are protected by DRM and are identi-
fied with the symbol f@ will not play.
Data security: never store important information
on 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 medium, the MMI will revert
to the local Gracenote metadata database or
search online if necessary. See > page 207, On-
line additional data. However, in some cases, the
additional information may not be displayed.

Checking and Filling

Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

A WARNING
— The engine compartment in any vehicle is a
potentially dangerous area. Stop the engine,
switch the ignition off, and allow the engine
to cool before working in the engine com-
partment. Always follow the information
found in > page 221, General information.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the
coolant in the original container and away
from children. There is a risk of poisoning.

® Note
Do not continue driving if the coolant expan-
sion tank is empty. Do not add any coolant,
because air could enter the cooling system
and damage the engine. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.
