use a spare tire* that is the same
circumference as the regular
tires.
&_ WARNING -
-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
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.

Please note the important safe­
ty precautions regarding tire pressure

limits
¢ page 295.
Tires and vehicle load limits
There are limits to the amount of
~ load or weight that any vehicle that is
overloaded will not handle
well and is more difficult to stop .
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.

Tire Pressure Monitoring
System (AS, S8)
(D General notes
A ppl ies to: AS, 58
Each t ire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
veh icle manufact urer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
be l, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your veh icle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure te ll­
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 on a 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
p roper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correc t tire p ressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your veh icle has also bee n eq uipp ed w ith a TPM S
mal function indicator to indicate when the sys­
tem is not operat ing 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 mi nute and then remain cont inuously
illuminated . This sequence will continue upon
Wheels
subsequent vehicle start-ups as long as the mal ­
function exists .
When the malfunction indicator is illuminated ,
the sys tem may not be able to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nsta llation of replacement or alternate tires or
whee ls on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replac ing one or
more tires or wheels on your vehicle to ensure
that the replacement or a lternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: A8, 58
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig. 269 I n strument cluste r: indicator light with messa ge
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and vibration characteristics of the individu­
al tires.
If the press ure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the location of that
tire will be indicated.
T he tire press ures 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

- the tire pressure in one or more tires is too low.
- the tire has structural damage .

pressure: System malfunction!.
Ifmm appears
after switching the ignition on or while driving
and the
IE indicator light in the instrument clus­
ter blinks for approximately one minute and then
stays on , there is system malfunction . Try to
store the correct tire pressures¢
page 302. If
the indicator light does turn off or turns on again
after a short period of time, drive to an author­
ized Audi dealer or authorized Audi Service Facili­
ty immediately to have the malfunction correct­
ed .
A WARNING
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steer ing or braking maneu­
vers . Stop as soon as possible and check the
t ir es and their pressure .
- The driver is responsible for maintaining the
correct tire pressure. You must check the
t ire pressure regularly.
- Under certain conditions (such as a sporty
dr iv ing style, winter cond itions 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
vehicle damage or accidents .

(D 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 tires with the identification "AO" or
"RO" ¢
page 290 have been matched with
your Audi tire pressure monitoring system.
We recommend that you use these tires.
Storing tire pressures
App lies to: AB, 58
If the tire pressure changes or a tire is replaced ,
it must be confirmed in the Infotainment sys­
tem.
... Make sure before storing that the tire pressur es
of all four tires meet the specified values and
are adapted to the load ¢
page 291.
... Switch the ignition on.
... Select: the
ICARI funct ion button> Car Systems
control button > Servicing & checks > Tire
pressure monitoring
> Store tire pressure >
Yes, store now.
(D Tips
Do not store the tire pressures if snow chains
are installed. Othe rw ise the system could
malfunction.
