Troubleshooting
The information that follows lists some trouble-
shooting options. They depend on the equip-
ment.

Problem Solution

Audi music interface/Bluetooth
audio player: the mobile device is
not supported.
Read the instructions in the chapter > page 202, Multimedia
connections/> page 201, Bluetooth audio player.

Audi music interface: the mobile
device is not recognized as a
source.
For many mobile phones or mobile devices, playback is not possi-
ble when the battery level is too low (less than 5% charge level).
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: malfunc-
tions during audio playback
through an iPod touch/iPhone.
The Bluetooth audio player function is switched on. Switch this
function off > page 213 when you are not using the Bluetooth
audio player.

Audi music interface: audio play-
back through the connected mo-
bile device is not possible.
Make sure the USB mode M7P is selected in the settings on your
mobile device.

Bluetooth audio player: interfer-
ence with track display and audio
playback.

Playback interference can occur when using the Bluetooth audio
player if a music player app from a third party provider is open.
Audi recommends using the integrated media player on your
Bluetooth device (such as a smartphone).

by the tire manufacturer. This in-
formation is used to contact con-
sumers if a tire defect requires a
recall.
Vehicle capacity weight
means the rated cargo and lug-
gage load plus 150 lbs. (68 kilo-
grams) times the vehicle's desig-
nated seating capacity.
Vehicle maximum load on the
tire
means that load on an individual
tire that is determined by distrib-
uting to each axle its share of the
maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual
tire that is determined by distrib-
uting to each axle its share of the
curb weight, accessory weight,
and normal occupant weight (dis-
tributed in accordance with > ta-
ble on page 247) and dividing by
two.
Occupant loading and distri-
bution for vehicle normal load

number of seating positions. Re-
fer to the table > table on
page 247 for the number of peo-
ple that correspond to the vehicle
normal load.
New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au-
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace-
ment parts.
>New tires do not yet have the
optimal gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
> Only use tires with the same de-
sign, size (rolling circumfer-
ence), and as close to the same
tread pattern as possible on all
four wheels.
>Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
> Audi recommends using Audi
Genuine Tires. If you would like
to use different tires, please
note that the tires may perform >

Data privacy

— How various systems in your vehicle were oper-
ating;
— Whether or not the driver and passenger safety
belts were buckled/fastened;
— How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
— How fast the vehicle was traveling.
These data can help provide a better understand-
ing of the circumstances in which crashes and in-
juries occur. NOTE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs;
no data are recorded by the EDR under normal
driving conditions and no personal data (e.g.
name, gender, age, and crash location) are re-
corded. However, other parties, such as law en-
forcement, could combine the EDR data with the
type of personally identifying data routinely ac-
quired during a crash investigation.
To read data recorded by an EDR, special equip-
ment is required, and access to the vehicle or the
EDR is needed. In addition to the vehicle manu-
facturer, other parties, such as law enforcement,
that have the special equipment, can read the in-
formation if they have access to the vehicle or the
EDR.
Data usage
Audi can read out the information stored in the
data memories or similar data, or give this infor-
mation to third parties, especially in the follow-
ing situations:
— If the vehicle owner or lessee agrees
— If there is an official request from the police
— Ifa court or authorities request it
If legally permitted, Audi can also use the data
for analysis of vehicle operation and safety per-
formance or provide this data to third parties for
research purposes.
Transmitted information
Data collection
Applies to: vehicles with data collection
Depending on the country, Audi may collect data
for the following purposes, for example: offer
and product optimization, public safety, provision
278
of Audi connect remote vehicle services, and
adaptation to customer expectations. For exam-
ple, various technical function data, environmen-
tal data, driving data, and usage data will be col-
lected for a specific purpose and forwarded to
Audi. The data will be sent from the vehicle at
the time the data was collected.
Applies to: MMI: You can find additional informa-
tion about data collection in the MMI. Select on
the home screen: SETTINGS > General > Legal
notes > About Audi connect.
If you would like to deny data transmission to
Audi, contact an authorized Audi dealer or au-
thorized Audi Service Facility for more informa-
tion. You also have the option to deactivate data
transmission within the privacy settings.
aE La ata ae)
Applies to: vehicles with Audi connect
> Applies to MMI: Select on the home screen:
SETTINGS > Privacy settings.
When using Audi connect services or during data
collection, data will be transmitted from the ve-
hicle.
> To display additional information about the pri-
vacy settings and the associated symbols in the
status bar, press @ in the MMI.
Requirement: the ignition must be switched on.
Setting the maximum privacy settings
When the Activate privacy mode function is
switched on, the data connection is deactivated
or sending of data is restricted, but all safety-re-
lated, legal, or contractually required Audi con-
nect services remain activated. The majority of
the Audi connect services are deactivated.
When the function is switched off, the data con-
nection will be available in order to use Audi con-
nect
services.
Adjusting individual privacy settings
In the MMI, you can adjust individually which da-
ta should be transmitted from the vehicle. If you
switch on a data category, the data will be trans-
mitted.

Service information is made available as soon as

Driving in other
countries
Government regulations in the United States and
Canada require motor vehicles to comply with
emissions regulations and safety standards.
Therefore, vehicles that were produced for the
U.S. and Canadian markets are different from
vehicles produced for other countries.
If you plan to use your vehicle outside of the
United States or Canada, it is possible that:
— Fuel may have a significantly lower octane rat-
ing. Unsuitable fuels can cause engine damage.
— Proper maintenance and repair work may not
be possible because special service equipment,
tools, or measuring devices needed for your ve-
hicle may not be available.
— Replacement parts may not always be availa-
ble.
— Navigation systems for vehicles built for the
U.S.A. and Canada will not necessarily work in
Europe, and may not work in other countries.
() Note
Audi is not liable for damage to the vehicle re-
sulting from these country-specific differen-
ces.
Maintenance, repairs,
and technical modifi-
cations
Observe the safety precautions > page 221, Gen-
eral information and > page 264, Raising the ve-
hicle.
General information
Due to the increasing complexity of technology in
these vehicles, as well as the safety and environ-
mental standards that apply, you can only per-
form a very limited amount of repairs and modifi-
cations to the vehicle yourself.
Proof of maintenance work may be required to
submit a claim within the warranty period.
We recommend that you have your vehicle serv-
iced by an authorized Audi dealer or authorized
Audi Service Facility and that Audi Genuine Parts
and Audi Genuine Accessories are used. This
helps to ensure that your vehicle's functionality,
performance, and safety are not impaired.
Maintenance and repairs
Your vehicle was designed to help keep mainte-
nance requirements to a minimum. Some regular
maintenance is required to help ensure that your
vehicle runs in a safe, economical, and reliable
manner. Please refer to your Warranty & Mainte-
nance Booklet for more detailed information
about vehicle maintenance.
When operating the vehicle under more extreme
operating conditions, for example when outside
temperatures are very low or in very dusty envi-
ronments, certain maintenance should be per-
formed between the specified intervals.
