2012 AUDI A8 stop start

24 2 T ire s and wheel s
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the t ires on your vehicle.
I t is important to check the tire pressu re when
the tires a re cold.
- Read the requ ired t ire pressure from the tire
pressure label. The tire pressure labe l is lo ­
cated on the drive r's side 8-p illar.
- T urn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressu re gauge on the valve.
- The tire pressures should only be checked
and adjusted when the tires are cold. The
sl igh tly ra ised p ressu res of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Re insta ll the va lve stem cap on the valve .
When should I check the ti re pres sure ?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before start ing a jou rney. Do not
fo rget to check the tire pressure for the spare
wheel
i::!> page 258.
When should I adju st the tire p re ss ure s?
Adjust the tire pressure to the load you are
carry ing . After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then
sto re t he new ti re press ures in the t ire pres­
sure mon itor ing system*
i::?> page 253.
_8 WARNING
Incorrect tire pressures and/or underinf la­
tion can lead sudden tire failure, loss of
contro l, co llision, ser ious persona l injury
or even death.
- When the warning symbo l
RI] appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla­
t ion can cause increased t ire wear and
can affect the handling of the veh icle and
stopp ing ability. -
Incorrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and sudden de­
flation, caus ing loss of veh icle control.
- The driver is responsible for the correct
tire pressures for all tires on the veh icle.
The applicable pressure values are locat­ ed on a sticke r on the dr iver's s ide 8-pil­
lar.
- Only when all tires on the vehicle are fil­ led to the correct pressure, the t ire pres­
sure mon itor ing* system can work cor­
rectly.
- The use of incorrect t ire p ressure va lues
can lead to acc idents or other damage.
Therefore it is essential t hat the drive r
observe the spec ified tire pressure values
for the tires and the correct pressures for
the function of the t i re press ure monitor­
ing system*.
- Always inflate tires to the recommended
and correct ti re press ure before driving
off.
- Driving with underinflated tires bend
more, letting them get too hot resulting
in tread separation, sudden tire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire failure
and loss of control.
- If the tire pressure is too low or too high,
the t ires will wear prematurely and the
veh icle w ill not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
tion to check the t ire p ress ure and add
a ir as req uired.
Q) Note
Driving w ithout valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory insta lled
valve stem caps o n all whee ls are sec urely
mounted on the valve.

254 Tires and wheels
remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunction exists.
When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your veh icle to ensure that the re­
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Appl ies to vehicles: with tire pressure monitoring sys te m
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. 188 Display: underinflation warning
Fig. 189 Display: System malfu nction
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividual tires. If the pressure decreases in one
or more tires, this is indicated in the instru- ment
cluster with a warning symbol
[I] and a
message
r=> fig. 188.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad­
justed (e.g. when switching between partial
and full load pressure) or after changing or re­
plac ing a tire on your vehicle
r=> page 255. You
can find the recommended tire pressures for
your vehicle on the Label on driver's side 8-pil­ lar
¢ page 239.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tire has structural damage,
- the tire pressure was changed, wheels rotat -
ed or replaced but the TPMS was not reset
r=> page 255.
Warning symbols
[I] Loss of pressu re in at least one tir e ¢ ,&. .
Check the tire or tires and replace or repa ir if
necessary. The indicator light
[I] in the instru­
ment cluster also illuminates
¢page 11 .
Check/correct the pressures of all four tires
and reset TPMS via MMI.
IIQllfl (Tir e Pressure Monitoring System) Tire
pressure! System malfunction .
If IIQIS, appears after switching the ignition
on or while driving¢
fig. 189 and the indica­
tor light
[I] in the instrument cluster blinks
f or approximately one minute and then stays
on, there is a system malfunction . See your
authorized Audi dealer as soon as possible.
A WARNING
-- If the tire pressure indicator appears in
the instrument cluster display, one or more of your tires is significant ly under­
inflated. Reduce you r speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In­
flate the tire pressure to the proper pres-
sure as indicated on the vehicle's tire .,..
