High-voltage system


— Only change cables in a dry environment.
— The Audi charging system may only be used
as a complete unit consisting of the power
cables, the control unit, and the vehicle ca-
ble. Depending on the country, the total
length of the power cable, control panel and
vehicle cable may be restricted, for example
to 24.6 feet (7.5 m) in the USA. Audi recom-
mends using only cables approved by Audi.
@) Tips
The power cable with the power connector for
industrial sockets and the Audi charging sys-
tem control unit are designed to work togeth-
er. Changing the power cable to another con-
nector type may reduce the available charging
power of the entire system. Limitations on
the ability to transfer power (current capacity)
depending on the phase and the number of
available phases may affect the available
charging power.

differently even if they are the
same size > A.
>If you would like to equip your
vehicle with a tire and rim com-
bination that is different from
what was installed at the facto-
ry, consult with an authorized
Audi dealer or authorized Audi
Service Facility before making a
purchase > A.
Because the spare tire® is differ-
ent from the regular tires instal-
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re-
placed with a regular tire as soon
as possible.
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds. For this rea-
son, in case of emergency, only
use a Spare tire* that is the same
circumference as the regular tires.


Z\ WARNING
—Do not use steel rims that are
17 inches or larger. Otherwise,


damage to the vehicle and an
accident could result.
—Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
—For technical reasons, it is not
possible to use tires from oth-
er vehicles. In some cases, you
cannot even use tires from the
same vehicle model.
—Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif-
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
—Only use tires that are more
than six years old when abso-
lutely necessary and drive
carefully when doing so.
—Do not use run-flat tires on
your vehicle. Using them when

Wheels


ZA\ WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see S page 272, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Loose wheel warning
Applies to: vehicles with loose wheel warning

Within the limits of the system, the loose wheel
warning in the instrument cluster warns you if
one or more wheels are loose.
Using the ABS sensors, the loose wheel warning
system compares the vibration characteristics of
the individual tires. If one or more wheels are
loose, it will be indicated in the instrument clus-
ter display with the & indicator light and a mes-
sage. If only one wheel is affected, the location
of that wheel will be indicated.
Messages
fi Wheel bolts loose. Please safely stop the ve-
hicle and check all wheel bolts!
Loose wheel warning for at least one wheel > A\.
Check the wheel bolts on all wheels with the
wheel wrench (vehicle tool kit). Have the tighten-
ing specification checked as soon as possible with
a torque wrench. Drive carefully until then. For
the correct tightening specification, see
=> page 272, Finishing.
fl Wheel assessment active. Please continue
driving carefully
After this message appears and you have checked
the wheel bolts, the assessment phase begins
when the vehicle is in motion. This may take sev-
eral minutes.

fi Loose wheel warning: malfunction! See
owner's manual
There is a system malfunction. Drive immediately
to an authorized Audi dealer or authorized Audi
Service Facility to have the malfunction repaired.

Z\ WARNING
Wheel bolts that are tightened incorrectly can
become loose and result in loss of vehicle con-
trol, which increases the risk of an accident.
— If a message appears, reduce your speed im-
mediately and avoid any hard steering or
braking maneuvers. Stop as soon as possible
and check the wheel bolts.
— Check your wheels for damage. Have the
damaged wheels checked and/or replaced
immediately by an authorized Audi dealer or
authorized Audi Service Facility.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the message may be delayed.
— The driver is responsible for ensuring that
the wheels are attached correctly.
(i) Tips
— The loose wheel warning system can also
stop working when there is an ESC malfunc-
tion.

— Using snow chains may result in a system
malfunction.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.
> Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 241. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.

Wheels

As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving ona signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
If the tire pressure monitoring indicator
appears
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor-
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light @ and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored again each
time you change the pressures (switching be-
tween partial and full load pressure) or after
changing or replacing a tire on your vehicle
= page 260. The tire pressure monitoring system
only monitors the tire pressure you have stored.
Refer to the tire pressure label for the recom-
mended tire pressure for your vehicle
=> page 251, fig. 158.
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-
ing if:
— The tire pressure in one or more tires is too low
— The tires have structural damage
— The tire was replaced or the tire pressure was
changed and it was not stored > page 260
— Tires that are only partially used are replaced
with new tires
Indicator lights

Data privacy

typically 30 seconds or less. The EDR in this vehi-
cle is designed to record such data as:
— 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.
Assist system monitor
This vehicle is equipped with an Assist System
Monitor (ASM). The ASM collects data that is not
stored by the EDR in the event of an accident. The
main task of the ASM is to make it possible to un-
derstand the role and the behavior of the assist
systems in these accident situations. In addition
to the data that the EDR stores, the ASM records
data related to the assist systems starting sever-
al seconds before the accident or near-accident.
The data collected by ASM depends on the equip-
ment and may include the following information:
status information of the assist systems (for ex-
ample, if they are switched on or off, system
events, etc.), control interventions (for example,
by ESC, ABS, Audi pre sense™, etc.), and assist
systems settings (such as speed settings).
Special devices and access to the vehicle or to the
ASM are necessary in order to read the data from
282
the ASM memory. In addition to the vehicle man-
ufacturer, third parties such as law enforcement
authorities can also read and analyze the stored
data if they have access to the vehicle or to the
ASM.
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
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.
