switched on, for example because it is out
of the vehicle range or the Bluetooth func-
tion is switched off, then a previously paired
secondary phone is automatically connected
as the primary phone.
— You can send and receive messages on your
primary phone as well as on your secondary

sponsibility for safety in traffic. Never operate
mobile devices while driving, because this in-
creases the risk of an accident.

@) Note
— Remove the connector from the Audi music
interface carefully so it is not damaged.
— Use a USB extension cable to connect devi-
ces that have an integrated USB connector
(such as a USB stick) to prevent damage to
your USB device and the Audi music inter-
face.
— Extremely high or low temperatures that
can occur inside vehicles can damage mobile
devices and/or impair their performance.
Never leave mobile devices in the vehicle in
extremely high or low temperatures.
@ Tips
— When you switch the ignition off, the USB
ports are still supplied with power until the
energy management intervenes.
— Do not use an additional adapter or USB ex-
tension cable to connect mobile devices to
the Audi music interface that already have a
cable or that must be connected with a USB
adapter > page 175. Using an additional
adapter or US extension cable may impair
functionality.

Problem Solution

Audi music interface/Bluetooth au-
dio
player: mobile device is not sup-
ported.
Read the instructions in the chapter > page 175, Multimedia
connections/=> page 172, Bluetooth audio player.

Audi music interface/AUX input: the
volume is too high/too low when
starting playback through the AUX in-
put.
Adjust the volume of the mobile device to approximately 70%
of the maximum output > page 780, Input level.

Audi music interface: the mobile de-
vice
is not recognized as a source.
For many cell phones or mobile devices, playback is not possi-
ble when the battery Level is too low (less than 5 % of its ca-
pacity). The mobile device will only be recognized as a media
source in the MMI after connecting if the battery charge level
is sufficient.

Audi music interface: malfunctions
during audio playback through an
iPod/iPhone.
The Bluetooth audio player function is switched on. Switch
this function off > page 7192 when you are not using the Blue-
tooth audio player.

AUX input: there is static when con-
necting and disconnecting the AUX
connection cable.
When connecting and disconnecting, the External audio play-
er source is already selected. Before connecting or disconnect-
ing the mobile device, either mute the device (see
=> page 193) or switch to a different audio source (for exam-
ple > page 164, Opening the radio).

Bluetooth audio player/Wi-Fi audio
player: audio playback interference.
Only one interface should be actively used at a time to prevent
issues during playback.

Wi-Fi audio player: audio playback in-
terference.
Audio playback interference can occur on some cell phones if
the Internet connection in the vehicle was not established
through the SIM card reader* on the MMI control panel and
the mobile data option on the cell phone is switched on. De-
activate the mobile data option on your cell phone.

Jukebox: tracks on the imported play-
list are grayed out.
When importing playlists, all of the files themselves must be
imported.

Jukebox: imported tracks cannot be
played or found.
If you cannot find imported tracks in the media center, they
may not be supported. Only copy supported files > page 783
to the Jukebox.

Wi-Fi audio player: multiple devices
are connected to the Wi-Fi hotspot. A
media player (such as a smartphone)
appears as the media source and can-
not be changed.
Close the myAudi app on the connected devices (such as
smartphones) that are not being used as the Wi-Fi audio play-
er. Likewise, close the UPnP server apps or the media permis-
sions on the integrated UPnP/DLNA server. Connect the de-
sired device as a Wi-Fi audio player > page 173.


Online media: connection failed be-
tween the MMI and the myAudi app.

To establish a connection to the MMI, the MMI connection
switch must be switched on in the myAudi app status screen.

fore coming into contact with any igni-
tion system components!

The catalytic converter can be damaged
"271i if the oil level is too high!

Always follow the instructions in the op-
aa erating manual.


ZA\ WARNING
— Turn the engine off.
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Allow the engine to cool.
— Keep children away from the motor com-
partment.
— Never spill fluids on a hot engine. These flu-
ids (such as the freeze protection contained
in the coolant) can catch fire.
— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— 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.
—The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure. There
is a risk of burns
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
— Due to the risk of electric shock, never touch
the ignition cable or other components in
the electronic high-voltage ignition system
when the engine is running or is starting.
— If a gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“P” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
move any jewelry and/or ties, tie back long
hair, and make sure all clothing fits close
to the body to reduce the risk of anything
becoming caught in engine components.
— Pay attention to the following warnings list-
ed when work on the fuel system or on the
electrical equipment is required.
— Do not smoke.
— Never work near open flames.
— Always have a working fire extinguisher
nearby.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to exhaust and chemi-
cals to as short a time as possible.

Observe the safety precautions > page 200, Gen-
eral information.
Checking the brake fluid level
> Read the brake fluid level on the brake fluid
reservoir > page 203, fig. 168. The brake fluid
level must be between the MIN and MAX mark-
ings > A\.
The brake fluid level is monitored automatically.
Message
EG / @® Brakes: stop vehicle and check brake
fluid level
Stop the vehicle and check the brake fluid level.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
Changing the brake fluid
Brake fluid should be changed at regular inter-
vals. Have the brake fluid changed by an author-
ized Audi dealer or authorized Audi Service Facili-
ty. The authorized Audi dealer or authorized Audi
Service Facility will inform you of the replace-
ment intervals.
ZX WARNING
— If the brake fluid level is below the MIN
marking, it can impair the braking effect and
driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This
could impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
— The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized
Audi Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-

ard (FMVSS) 116 DOT 4, Class 6.
@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.

— Do not allow any brake fluid to come into
contact with the vehicle paint, because it
will corrode the paint.
