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. 255 Display: underinflation warn ing
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
RE
warning symbol and a
message ¢
fig . 255 .
The dr iver message in the
display goes out after 5 seconds. The dr iver
message can be displayed again by pressing
the
!CHECK
I
button. If only one tire is affect-
ed, the display will indicat e its position.
The tire pressure monitoring must be reset via
MMI each time the pressures are adjusted (e.
g. when switch ing between partial and full
load pressure) or after changing or replac ing a
tire on your vehicle ¢
page 303.
The TPMS in-
dicator only monitors the tire pressure that
you have previously stored. You can find the
recommended tire pressures for your vehicle
on the label on dr iver's side 8-pillar
¢page 278.
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 tires is too
low,
- the tire has st ructural damage,
- the tire pressure was changed, whee ls rotat-
ed or replaced but the TPMS was not reset
¢ page 303,
- the spare tire* is mounted.

Loss of pressure in at least one tire¢ ,&..
Check the tire or tires and replace or repair if
necessary. The

indicator light in the instru -
ment cluster also illuminates

Check/correct the pressures of all four tires
and reset TPMS via MMI.

an authorized Audi dealer or authorized repair
facility to have the malfunction corrected.
A
WARNING
......_
- If the tire pressure ind icator appears in
the instrument cluster display, one or
more of your t ires is sign ificant ly under-
inflated . Reduce your speed immediately
and avoid any hard steer ing or braking
maneuvers. Stop as soon as possib le and
check the tires and their pressu res. I n-
flate t he ti re pressure to the proper pres-
sure as indicated on the vehicle's tire
pressure label
r=:>page 278.
Driving on a
sign ificantly under-inflated tire causes
the t ire to overheat and can lead to tire
fa il ure. Under-inflation also is likely to
impair the vehicle's handl ing and stop-
ping ability .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly.
- Under certain conditions (such as a spor-
ty driv ing style, winter conditions or un-
paved roads), the pressure monitor indi-
cator may be delayed .
-Ask you r aut horized Aud i dealer if run-
flat t ires may be used on you r vehicle.
