- For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
dea ler· risk of an accident!
- If the veh icle or the circuit interrupter is
scrapped, all applicab le safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modu les and pretension ­
ers might be classified as Perch lorate Materi­
al -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requirements and we recom­
mend that you have your dealer perform this
serv ice for you .
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using t ire-r im
comb inat ions not approved by Audi, lower ing the
veh icle, chang ing the st iffness of the suspens ion,
including the springs, suspension struts, shock
absorbers etc. can change the forces that are
measured by the airbag senso rs and sent to the
electronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of changes may reduce the force levels meas ured by
the sensors and prevent the airbag from deploy­ ing when it should .

A WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim comb inations can
change Advanced Airbag performance and in­
crease the r isk of serious personal injury in a
crash.
- Never insta ll suspension components that
do not have the same performance charac­
ter istics as the components origina lly ins tal­
led on you r vehicle.
- N ever use tire-r im combinations that have
no t been approved by Aud i.
A WARNING
It ems stored between the safety belt buckle
and the center conso le can cause the sensors
in the buckle to send the wrong information
to the electronic contro l module and prevent
the Advanced A irbag System from working
proper ly.
- Always make sure that nothing can interfere
with the safety belt buckles and that they
are not obstructed.

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions inc:::> page 295,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a

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

Description
App lies 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 Infotainment system
o page 304. It also
compares the current tire pressures with the
stored tire pressures and gives a warning in the
driver information system if the tire pressure is
different from what is stored
o 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 replacing a tire, or
- if wheels with new wheel sensors are used,
you must store the tire pressures again
opage 305.
A WARNING
--The tire pressure monitoring system assists
the driver in monitoring tire pressures. The
driver 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 high. This could
result in serious damage to the tire and
even cause the tire to burst, increasing the
risk of an accident.
- 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 construction that could cause the tire to
burst, for example. Inspect your tires regu­
larly.

Storing new tire pressures
Applies to: S8 plus
Correctly stored tire pressure specifications are
necessary for reliable tire pressure monitoring .
.. Check the tire pressures in all wheels.
1> If necessary, correct the tire pressure according
to the spec ificat ions on the sticker on the driv ­
er's door ~
page 291 . Only correct the press ure
in tires whose tempera tu re is approx imately
the same as the amb ient temperature.
If the
tempera ture of the tire is highe r than the ambi­
ent a ir temperat ure, the tire pressure must be
increased approximately 3 PSI (0,2 bar) above
the va lue on the sticker.
.. Switch the ignition on.
.. Se lect :
I CARI funct ion button > Car systems >
T ire pr essure monitoring > Store tire pres­
s ure s.
After stor ing, the tire pressure mon itor ­
ing system measures the c urrent tire pressures
and stores them as the new specified p res­
s ur es .
.. If the changed tire press ures are not displayed
in t he Infotainment system, dr ive the veh icle
for approximate ly 10 minutes so that the sen ­
sor signal from the whee ls is received again .
