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. 205 Display: underinflation warning
Fig. 206 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
rD] and a
message
c:> fig . 205.
The tire pressure monitoring system must be
reset via MMI each time the pressures are ad
justed (e.g. when switching between partial
and fu ll load pressure) or after changing or re
placing a tire on your vehicle
c:> page272 . 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
c:>page247.
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

- the spare tire* is mounted .

Check the tire or tires and replace or repair if
necessary. The indicator light

Ifljl appears
after switching the ignition on or while driving
¢
fig. 206 and the indicator light rD] 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
c:> page 272. 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.
_& 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 247 . 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.

276 What do I do n ow ?
After changing a wheel
A wheel change is no t complete without the
doing the following .
.. Always store the vehicle tool kit, the jack*
and the replaced tire in the luggage com
partment ¢
page 134.
.. Check the tire pre ssur e on the spare wheel
immediately after mount ing it .
.,. As soon as possible, have the
tightening
torqu es
on all wheel bol ts checked with a
torq ue wrench. The correct tightening tor
que is 90 ft lb (120 Nm) .
.. Have the flat tire
replaced as soon as possi
ble.
@ Tips
- If you notice t hat the wheel bolts are
corroded and difficult to t urn while
changing a t ire, they should be replaced
before you check the tighten ing torque.
- Drive at reduced speed unt il you have the
tightening torques checked .
- After changing a wheel, the tire pressure
i n a ll four tires must be checked/correct
ed and the tire pressure mon itor ing indi
cator must be stored in the MMI
