2015 AUDI TT ROADSTER sensor

remain continuous ly illuminated . This se ­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signa l low tire pressure as intended. TPMS
malfunct ions may occur for a variety of rea­
sons, including the installat ion of replace­
ment or alternate tires or wheels on the veh i­
cle that prevent the TPMS from funct io ni ng
properly. Always check the TPMS malfunct ion
tellta le afte r replacing one or more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with 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.
F ig. 1 41 Disp lay : under in fla tion warn ing
Using the ABS sensors, the tire pressure moni ­
toring system compares the t ire tread circum­
fe rence and vibration characteristics of the in­
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indicated in the instru­
ment clus ter with a warning symbol
[I] and a
message
'* fig. 141. The dr iver message in the
d isp lay goes out after 5 seconds . The driver
message can be d isplayed again by pressing
the
! CHECK I button @¢ page 10, fig . 3 . If on ­
ly one tire is affected, the display will indicate
its pos ition.
The ti re pressure monito ring m ust be reset in
the menu display each time the pressures are
ad justed (e.g. when switching between parti-
Tire s an d wheel s 199
al and fu ll load pressure) or after changing o r
replacing a tire on your vehicle '*
page 200.
The TPMS indicator on ly mon itors the t ire
pressure that you have previously stored . You
can f ind the recommended tire pressures for
your vehicle on the label on the driver's door
pillar ¢
page 184 .
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the t ire press ure in one or more tires is too
low,
- the tire has structural damage,
- the t ire press ure was changed, wheels rotat -
ed or rep laced but the TPMS was not reset
¢ page 200.
Warning symbo ls
[I] Loss of press ure in at least one tire'*& .
Check the tire or tires and rep lace or repa ir if
necessary . The indicator light
[I] in the instru ­
ment cluster a lso i lluminates
¢ page 13.
Check/correct the press ures of all four tires
and reset TPMS in the menu display .

pre ssure! System malfun ction . Ifll appears
after switching the ign it ion on or while dr iving
and the indicator light
[I] in the instrument
clus ter blinks fo r approximately one m inute

-If the tire pressure indicator appears in
the instrument cluster display, one or
more of your t ires is significant ly under­
inflated. Reduce your speed immediately
and avoid any hard steer ing or b rak ing
maneuvers. Stop as soon as possib le and
check the tires and their pressu res . In­
