and may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
If the tire pressure monitoring indicator
appears
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor-
ing system compares the tire tread circumfer-
ence and vibration characteristics of the individu-
al tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light (BJ and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored again each
time you change the pressures (switching be-
tween partial and full load pressure) or after
changing or replacing a tire on your vehicle
<page 282. The tire pressure monitoring system
only monitors the tire pressure you have stored.
Refer to the tire pressure label for the recom-
mended tire pressure for your vehicle
page 273, fig. 169.
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-
ing if:
~The tire pressure in one or more tires is too low
~The tires have structural damage
~The tire was replaced or the tire pressure was
changed and it was not stored > page 282
~Tires that are only partially used are replaced
with new tires
Indicator lights
if the [MB] indicator light turns on, there is a loss
of pressure in at least one tire «> A\ Check the
tires and replace if necessary. Check and correct
the pressures of all four tires and store the pres-
sure again > page 282.
[iS Tire pressure: malfunction! See owner's
manual
if [Ml appears after switching the ignition on or
while driving and the BJ indicator light in the in-
strument cluster blinks for approximately one
minute and then stays on, there is system mal-
function. Try to store the correct tire pressures
© page 282. In some cases, you must drive for
several minutes after storing the pressures until
the indicator light turns off. If the indicator light
does turn off or turns on again after a short peri-
od of time, drive to an authorized Audi dealer or
authorized Audi Service Facility immediately to
have the malfunction corrected.
~ If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu-
vers. Stop as soon as possible and check the
tires and their pressure.
