Tires and wheels
Tire pressure indicator appears
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. 200 Display: und erinflatio n warn ing
Fig. 201 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 tires, this is indicated in the instru-
ment cluster with a warning symbol
[9]
and a
message ¢
fig. 200.
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-
placing a tire on your vehicle ¢
page 269 .
The
TPMS indicator only monitors the tire pres-
sure that you have previously stored. You can
find the recommended tire pressures for your
vehicle on the label on driver's side 8-pillar
¢ page 244.
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,
- th e tire pressure was changed, wheels rotat-
ed or replaced but the TPMS was not reset
¢ page 269.
- the spare tire* is mounted .
Warning symbols
[9]
Loss of pressure in at least one tire ¢ &. .
Check the tire or tires and replace or repair if
necessary. The indicator light
[9]
in the instru-
ment cluster also illuminates
¢ page 12.
Check/correct the pressures of all four tires
and reset TPMS via MMI.
Ill
(Tire Pressure Monitoring System) Tire
pressure! System malfunction . Iflll
appears
after switching the ignition on or while driving
¢
fig. 201
and the indicator light
[9]
in the in-
strument cluster blinks for approximately one
minute and then stays on, there is a system
malfunction . Attempt to store the correct tire
pressure ¢
page 269.
If the indicator light
does not turn off or if it turns on shortly
thereafter, immediately drive your vehicle to
an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
A
WARNING
- If the tire pressure indicator appears in
the instrument cluster display, one or
more of your 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-
flate the tire pressure to the proper pres-
sure as indicated on the vehicle's tire
pressure label ¢
page 244 .
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.
