2018 AUDI A8 TPMS

Wheels
under controlled conditions on a specified
government test course.
For example, a tire graded 150 would wear one
and one ha lf (11/2) times as well on the govern­
ment course as a tire graded 100 .
The relative performance of tires depends upon
the actual conditions of their use, howeve r, and
may depart significant ly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate .
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. Those grades represent the tire's
ability to stop on wet pavement as measured un­
der contro lled conditions on specified govern­
ment test surfaces of aspha lt and concrete. A tire
marked C may have poor traction performance
¢ & .
Temperature
The temperatu re grades are A (t he highest), B ,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate ­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire
fa ilure¢ fr:. .
The grade C corresponds to a leve l of perform ­
ance which a ll passenger car tires must meet un­
der the Federa l Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher leve ls
of performance on the laboratory test wheel than
the mi nimum required by law.
A WARNING
-
The traction grade assigned to this tire is
based on straight-ahead braking traction
t ests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
300
A WARNING
The temperature grade for t his tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in comb ination , can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are
properly inflated and not over or under inflat­
ed .
Tire Pressure Monitoring
System
(AS, S8)
ill General notes
Applies to: AS, 58
Each tire, including the spare (if prov ided),
shou ld be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure labe l.
(If your veh icle has
tires of a different size than the size ind icated on
the ve hicle placard or tire inflat ion pressure la­
bel , you should determ ine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure mon itor ing system
(TPMS) that illum inates a low tire pressure tell­
tale when o ne or more of your tires is significant­
l y unde r-inflated. According ly, when the low tire
pressure telltale illum inates, you sho uld stop and
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi ­
cant ly under -inflated tire causes the tire to over­
heat and can lead to tire fai lure. Under-inflation
also reduces fue l eff iciency 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 dr iver's re ­
spons ibility to maintain correct t ire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure te lltale .

"" ......
"" .... 0 0 :c ' Your vehicle has also been equipped with a TPM S
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 cont inuously
illuminated . This sequence will continue upon
subsequent vehicle start-ups as long as the mal­
function ex ists.
When the malfunction indicator is illuminated,
the system may not be ab le to detect or signal
low tire pressure as intended . TPM S malfunctions
may occur for a var iety 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 System
indicator appears
Applies to: AS, 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. 268 Instrument clus ter: indicator light with message
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 ind icated in the instrument cluster
display with an indicator light
ti] and a message .
Wheels
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
c:> page 302. The tire pressure mon i­
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:> page 293, fig . 267 .
Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if :
- the t ire 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

Wheels
-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
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.
Using these tires is recommended.
Storing tire pressures

Description
Applies to: 58 plus
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem ­
perature and pressure in the tires . The data is
sent from these sensors to the control module by
radio frequency.
The Tire Pressure Monitoring System shows the
current pressures and temperatures of the tires
in the Infota inment system
c:> page 303 . It also
compa res the current tire pressures with the
stored tire press ures and gives a warning in the
driver information system if the tire pressure is
different from what is stored
c:> page 304.
The system does not detect if the stored tire
pressures match the recommended tire pres­
sures.
- Every time the tire pressures change, for exam-
ple when the load in the vehicle changes,
- after replac ing a tire, or
- if wheels with new wheel sensors are used,
you must store the tire pressures again
c:> page 304.
A WARNING
-The tire pressure mon itor ing system assists
the driver in monitoring tire pressures. The
dr iver is responsible for having the tires in­
flated to the correct pressure.
- Do not change the tire pressure when the
temperature of the tire is extremely high.
T his cou ld result in serious damage to the
t ir e and even cause the tire to burst, in­
creasing the risk of an accide nt.
Wheels
-A tire with low pressure flexes more . This
heats the tire up too much. This could cause
the tread to separate and even cause the
tire to burst, increasing the risk of an acci­
dent.
- The Tire Pressure Monitoring System does
not warn you of damage or defects in the
tire construct ion that could cause the tire to
burst, for example. Inspect your tires regu­
larly.
@ For the sake of the environment
Low tire pressure increases fuel consumption
and tire wear.
(D Tips
-The pressure of the spare t ire* is not mon i­
tored.
- If tires are replaced, the sensors/va lves do
not need to be removed or replaced. Just re­
placed the valve stem and, if necessary, the
valve and the whee l electronics . If you have
questions, see an authorized Audi dealer or
authorized Audi Service Facility.
Displaying tire pressures/temperatures
Applies to: 58 plus
Requirement: the ignition must be switched on.
.. Select: the I CAR! funct ion button > Car systems
> Service & control > Tire pressure monitor >
Display tire pressure .
The current tire pressures are shown in green and
yellow numbers in the Infotainment system:
-Green: the current tire pressure and the spec i­
fied tire pressure are approx imately the same .
-Yellow: the current tire pressure is too low
compared to the specified tire pressure .
The specified tire pressure is the last tire pres ­
sure that was stored
c:> page 304 .
Note that the tire pressure also depends on the
temperature of the tire . The tire pressure in­
creases as the engine becomes warmer while
driv ing.
