monitoring system
General notes
Appties to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and in-
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (Ifyour
vehicle has tires of a different size than the
size indicated on the vehicle placard or tire in-
flation pressure label, you should determine
the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According-
ly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a significantly un-
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation al-
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale. When the sys-
tem detects a malfunction, the telltale will
flash for approximately one minute and then
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
signallow 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
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the re-
placement or alternate tires and wheels allow
the TPMS to continue to function properly.

Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
c/uster informs you if the tire pressure is too
Low or if there is a system maLfunction.
Fig.1S6 Display: System malfunction
Using the ABS sensors, the tire pressure moni-
toring system compares the tire tread circurn-
ference and vibration characteristics of the in-
dividual tires. Ifthe pressure decreases in one
or more tires, this is indicated in the instru-
ment cluster with a warning symbol
g
and a
message q fig. 155. The driver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
the
[CHECKI
button
®
q page 10, fig. 3. If on-
ly one tire is affected, the display will indicate
its position.
The tire pressure monitoring must be reset in
the menu display each time the pressures are
adjusted (e. g. when switching between parti-
al and fullload pressure) or after changing or
replacing a tire on your vehicle q page 218.
Vou can find the recommended tire pressures
for your vehicle on the label on the driver's
door pillar q page 202.
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
qpage218.

pressure! System malfunction. IflDm ap-
pears after switching the ignition on or while
driving qfig. 156 and the indicator light gin
the instrument cluster blinks for approxi-
mately one mi nute 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 ofyour tires is significantly under-
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures. In-
fla te the tire pressure to the proper pres-
sure as indicated on the vehicle's tire
pressure label
q page
202. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop-
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor-
ty driving style, winter conditions or un-
paved roads), the pressure monitor indi-
cator may be delayed.
- Ask your authorized Audi dealer if run-
flat tires may be used on your vehicle.
Your vehicle registration becomes invalid
if yàu use these tires wh en not permit-
ted. Damage to your vehicle or accidents
could also result.
- Ifyou switch between standard and run-
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module.

Tips
- The tire pressure monitoring system
stops working when there is an ESP/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- Tires with the identification "AD" or "RD"
have been specially matched with your
Audi. We recommend using only these
tires because they meet the highest
standards regarding safety and driving
characteristics when used correctly. Your
authorized Audi dealer will gladly pro-
vide you with more information.
