Media

Media
Introduction
There are various media sources and connections
available in the MMI. For example, you can play
audio/video* files from the Jukebox* or connect
your mobile device to the Audi music interface*
and operate it through the MMI.
Notes
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.
Digital Rights Management: please note that
the audio/video* files are subject to copyright
protection.
The media sources 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, the Jukebox*, CDs/DVDs* or mobile devi-
ces. Audi is not responsible for damaged or lost
files and media.
Loading times: the more files/folders/playlists
that are on a storage medium, the longer it will
take to load the audio/video* files. Audi recom-
mends using storage media that only contain au-
dio/video files*. To decrease the time it takes to
load audio/video files*, create subfolders (for ex-
ample, for the artist or album). The loading time
will also increase when importing files.
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.
Restricted functionality: reset the Media set-
tings to the factory default settings if functional-
ity is restricted > page 190.
If functionality is restricted, reset the Jukebox* to
the factory default settings > page 190.

Message
EB 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.

ZA WARNING
— Never open the hood when there is steam or
coolant escaping from the motor 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 lifted.
— 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

> Applies to: using engine oil that meets the rec-
ommended specification: Add some more
engine oil again if necessary.
> Close the engine oil filler cap and push the dip-
stick
all the way in.
> Close the hood > page 202.

ZX WARNING
— When adding oil, do not let oil drip onto hot
engine components. This increases the risk
of a fire.
— 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.
206
Changing engine oil
Audi recommends having the oil changed at an
authorized Audi dealer or authorized Audi Serv-
ice Facility.
Observe the safety precautions > page 200, Gen-
eral 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, Audi recommends
having your engine oil changed by an authorized
Audi dealer or authorized Audi Service Facility.
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. >

Checking and Filling

— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.
— You can continue driving if the permitted
G12evo coolant additive was not added.
However, go to an authorized Audi dealer or
authorized Audi Service Facility immediately
to have the coolant replaced to reduce the
risk of engine damage.
— Due to the risk of engine damage, the cool-
ing system should only be refilled by an au-
thorized Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or
authorized Audi Service Facility can also pro-
vide
you with important information about
the recommended coolant additive.

ly above the upper marking.
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank >@).
208
If you must add coolant, use a mixture of water
and coolant additive. Audi recommends mixing
the coolant additive with distilled water.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cap.
> Remove the cover (1) > fig. 777 carefully to the

» Add the correct mixture ratio of coolant
> page 207 up to the upper marking @)
> fig. 177.
» Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
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.

Z\ WARNING
— The motor compartment in any vehicle is a
potentially dangerous area. Stop the engine
and allow it to cool before working in the
engine compartment. Always follow the in-
formation found in > page 200, General in-
formation.
— Never open the hood if you can see or hear
steam or coolant escaping from the motor
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 motor
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.
