266 Tires and wheels
wheels on your vehicle to ensure that the re-
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure mo nitoring 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. 213 Display: underinflation warning
Fig. 214 Display: System malfun ctio n
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 mo re tires, this is indicated in the instru-
ment cluster with a
IE warning symbol and a
message
c:>fig. 213. The driver message in the
display goes out after S seconds. The driver
message can be displayed again by pressing
the
!SET! button. If only one tire is affected,
the display will indicate its position.
The tire pressure monitoring system must be
reset via radio or MM!* each time the pres-
sures are adjusted (e. g. when switching be-
tween partial and full load pressure) or after
changing or replacing a tire on your vehicle
c:> page 267 . You can find the recommended
tire pressures for your vehicle on the label on
driver 's side B-pillar
c:> page 251 .
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
c:>page 267.
Warning symbols
IE Loss of pressure in at least one tire c:> .&,.
Check the tire or tires and replace or repair if
necessary. The
IE indicator light in the instru-
ment cluster also ill uminates
c:>page 13.
Check/correct the pressures of all four tires
and reset TPMS via radio or MMI* .
••NIP, <Tire Pressure Monitoring System) Tire
pressure! System malfunction .
If ••NI@ appears after switching the ignition
on or while driving
c:> fig. 214 and the IE i ndi-
cator light in the instrument cluster blinks for
approximately one m inut e and then stays on,
there is a system malfunction . See your au-
thorized Audi dealer as soon as possible .
_& WARNING
- If the tire pressure ind icato r appears in
the instrument cluster display, one or
more of your tires is significant ly 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-
flate the tire pressure to the proper pres-
sure as indicated on the vehicle's tire
pressure label
c:> page 251. Driving on a
sign ificant ly 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.
