phone service provider and especially when
using in other countries. A flat rate data
plan is strongly recommended. You can ob-
tain more information from your cell phone
service provider.
— In certain situations, the Wi-Fi hotspot data
connection may be established as a replace-
ment for the SIM card on your Wi-Fi device.
This feature depends on the configuration
of your Wi-Fi device and operating system.
This could result in fees depending on your
cell phone service provider, especially if you
are using this feature while abroad. A flat
rate data plan is strongly recommended.
For more information, contact your cell
phone service provider or refer to the own-
er's manual for your Wi-Fi device.

Wheels and Tires
General information
> Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
>If driving over curbs or similar
obstacles, drive slowly and ap-
proach the curb at an angle.
> Have faulty tires or rims re-
placed immediately.
>Protect your tires from oil,
grease, and fuel.
>Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
>Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.

J WARNING
—Never drive faster than the
maximum permitted speed for
your tires. This could cause the
tires to heat up too much. This
increases the risk of an acci-
dent because it can cause the
tire to burst.

214


—Always adapt your driving to
the road and traffic condi-
tions. Drive carefully and re-
duce your speed on icy or slip-
pery roads. Even winter tires
can lose traction on black ice.

() Note
—Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom-
mends winter tires during the
winter months. Low tempera-
tures significantly decrease
the elasticity of summer tires,
which affects traction and
braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
—Burnished, polished or
chromed rims must not be
used in winter driving condi-
tions. The surface of the rims
does not have sufficient corro-
sion protection for this and
could be permanently dam-
aged by road salt or similar
substances.

manufacture date
The manufacture date is listed on
the tire sidewall (it may only ap-
pear on the inner side of the tire):
DOT... 2220...
means, for example, that the tire
was produced in the 22nd week of
the year 2020.
@) Audi Original Tires

tires meet the highest standards
for safety and handling. An au-
thorized Audi dealer or author-
ized Audi Service Facility will be
able to provide you with more in-
formation.
@) Mud and snow capability
“M/S” or “M+S” indicates the tire
is suitable for driving on mud and
snow. /A\ indicates a winter tire.
Composition of the tire cord
and materials
The number of plies indicates the
number of rubberized fabric lay-
ers in the tire. In general: the
more layers, the more weight a
tire can carry. Tire manufacturers

must also specify the materials
used in the tire. These include
steel, nylon, polyester and other
materials.
@) Maximum permitted load
This number indicates the maxi-
mum load in kilograms and
pounds that the tire can carry.
@ Uniform tire quality grade

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 circumfer-
ence and vibration characteristics of the individu-
al tires. If the pressure changes in one or more
tires, this is indicated in the Infotainment system
display with an indicator light (J and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain-
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle > page 232. The tire pressure moni-
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
=> page 224, fig. 178.
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 tire has structural damage
— The tire was replaced or the tire pressure was
changed and it was not stored > page 232
— The spare tire” is installed

function. Try to store the correct tire pressures
=> page 232. In some cases, you must drive for
several minutes after storing the pressures until
the indicator light turns off. If the indicator light
does turn off or turns on again after a short peri-
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.

Z\ WARNING
— If the tire pressure indicator appears in the
display,
reduce your speed immediately and
avoid any hard steering or braking maneu-
vers. Stop as soon as possible and check the
tires and their pressure.
— The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.
— Under certain conditions (such as a sporty
driving style, winter conditions, or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
— Do not use run-flat tires on your vehicle. Us-
ing them when not permitted can lead to ve-
hicle damage or accidents.
(i) Tips
— The tire pressure monitoring system can al-
so stop working when there is an ESC mal-
function.

— Using snow chains may result in a system
malfunction.
— The tire pressure monitoring system in your
Audi was calibrated with “Audi Original
Tires” > page 227. Audi recommends using
these tires.
Storing tire pressures
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
If the tire pressure changes or a tire is replaced,
it must be confirmed in the Infotainment sys-
tem.
> Before storing the tire pressures, make sure the
tire pressures in all four tires meet the speci-
fied values and are adapted to the load
=> page 223.
