2011 AUDI TT ROADSTER inflation pressure

212 Tires and wheels
Tire pressure
monitoring system
General notes
Appl ies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and in­
f lated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has t ires 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 responsib ility to ma inta in correct tire
pressure , even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not operating properly. The
TPMS malfunction indicato r is combined with
the low tire pressure telltale. When the sys­
tem detects a malfunction, the telltale will
f lash for approximately one minute and then
remain continuously illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction exists. When the
malfunction indicator is illuminat­
ed, the system may not be ab le to detect or
s ignal 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
telltale after replacing one or more tires or
wheels on your vehicle to ens ure that the re­
placement or alternate ti res and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to veh icles : w ith tire pressure monitoring system
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. 151 Display : underinflatio n warning
Fig. 152 Display: System malfunction
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 t ires, this is indicated in the instru­
ment cluster with a warning symbol
g and a
message
r=:> fig. 151. Th e driver message in the
display goes out after 5 seconds. The driver
message can be displayed again by pressing
11--

the !CHECK I button @c:> page 10, fig. 3. If on­
l y one tire is affected, the display will indicate
its pos ition.
The tire p ress ure moni to ring m ust be reset in
the menu display each time the pressures are
adjusted (e .g. when switc hing between parti­
a l and full load pressure) or after chang ing or
replac ing a tire on your vehicle
c:> page 214.
You can find the recommended tire pressures
for your vehicle on the label on the driver's
door p illar
c:> page 198.
Tire tread circumference and vibration charac­
ter istics can change and cause a tire pressure
warn ing if:
- the tire pressure in one or more t ires is too
low,
- the tire has structural damage,
- the tire pressure was changed, whee ls rotat -
ed or replaced but the TPMS was not reset

.&, WARNING
- If the t ire pressure indicator appea rs in
the instrument cl uster d isplay, one or
more o f you r tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or bra king
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pressure to the proper pres-
.

pressure labe l
r=:>page 198. Driving on a
significantly under-inflated tire causes
the t ire to overheat and can lead to tire
fa ilure . Unde r-inflation also is l ikely to
impair the vehicle's handling and stop­
ping ability.
- The d rive r is respons ib le for maintaining
the co rrect tire pressures. You must
check the tire pressures regularly.
- Unde r ce rtain conditions (such as a spo r­
ty driving style, winter conditions or u n­
p aved roads), the pressu re monitor indi­
ca tor may be delayed.
- Ask you r authorized Aud i dea le r i f run­
f lat tires may be used on your vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
- If you switch between standard and run­
flat tires, an autho rized Audi dealer o r
qualified workshop must reprogram the
contro l modu le.
(D Tips
- The tire pressure monitor ing system
stops work ing when there is an ESP/ABS
ma lfunction.
- Us ing snow c hains may res ult in a system
ma lfunction.
- Tires wit h the identification "AO" or "RO"
have been specially matched with yo ur
Audi. We recommend using on ly these
tires because they meet the highest
standards regarding safety and dr iv ing
character istics when used correctly. Your
authorized Audi dealer wi ll gladly pro­
vide you with more information .
