Information about the services and the corre-
sponding app was accurate at the time this man-
ual was printed. The scope of services depends
on the country and equipment. There may be
changes over the service life of the vehicle.

ZA WARNING
— Always follow the information found in > AA
in General information on page 182.
— Driver messages, text messages, and illumi-
nated warning and indicator lights in the ve-
hicle always take priority over information
from the Audi connect services. The infor-
mation displayed by the Audi connect serv-
ices should not cause you to take safety
risks. This can result in the vehicle breaking
down in traffic and to serious injuries or ac-
cidents.
G) Tips
— Accessing specific data or controlling func-
tions remotely depends on the charge level
of the vehicle battery. Therefore, these
functions only have limited availability after
switching off the ignition.
— An eSIM card establishes the Internet con-
nection for Audi connect vehicle control
services. The costs for this are included in
the price of Audi connect vehicle control
services. The cell phone network, for exam-
ple, must be available to use these services.
Applies to: vehicles with Audi connect vehicle control

Media

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 222.
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 216, On-
line additional data. However, in some cases, the
additional information may not be displayed.

G) Tips
— Check for any connection requests on your
Bluetooth device.
— Multiple Bluetooth audio players can be
paired with the MMI, but only one at a time
can be active as a Bluetooth audio player
=> page 223.
— The supported media functions (such as
shuffle, list view, categories, search, op-
tions) depend on the Bluetooth device being
used.

Checking and Filling

> Turn the engine off.
> Open the hood > page 231.
> Unscrew the cap 7 for the engine oil filler
opening > fig. 168.
> Carefully add 0.5 quart (0.5 liter) of the correct
oil > page 233.

> Close the hood > page 231.
» Restart the ignition after two minutes and read

Checking the engine oil level.
> Applies to: using engine oil that meets the rec-
ommended specification: Add some more en-
gine oil again if necessary.

Z\ 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.
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 230, 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:

Z\ 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. >

@) 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.

Fig. 184 Sill: positioning the vehicle jack
> Place the vehicle jack from the vehicle tool kit
ona firm surface. Use a flat, stable support if
necessary. On a slippery surface such as tile,
you should use a non-slip pad such as a rubber
mat > /\.

AN WARNING
—To reduce the risk of injury, make sure no
one is in the vehicle before raising it.
— Make sure the vehicle jack is stable. The risk
of injury is increased when the ground is
slippery or soft, because the vehicle jack
could slide or sink.
— Only raise your vehicle with the vehicle jack
provided by the factory. If you use a vehicle
jack designed for another vehicle, your vehi-
cle could slip and cause injury.
— Position the vehicle jack only at the desig-
nated mounting points on the side sill and
align the jack. Otherwise, the vehicle jack
could slip and cause an injury if it does not
have sufficient hold on the vehicle.
—To reduce the risk of injury, do not raise any
other vehicles or other loads using the vehi-
cle jack provided by the factory.
—To reduce the risk of an accident, never start
the engine when the vehicle is raised.
—To reduce the risk of injury, no work should
be performed under the vehicle while it is
raised.

() Note
Do not lift the vehicle by the sill. Position the
vehicle jack only at the designated mounting
points on the side sill. Otherwise, your vehicle
could be damaged.
