Your vehicle has also been equipped with a TPMS
malfunction indicator to ind icate 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 cont inuously
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 ab le to detect or signal
low tire pressure as intended . TPMS malfunctions
may occur for a var iety 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 System
indicator appears
Applies to: AS, 58
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. 268 Instrument cluster: indicator light with message
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 ind icated in the instrument cluster
display with an indicator light
ti] and a message .
Wheels
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored in the Infotain-
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c:> page 302. The tire pressure mon i-
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:> page 293, fig. 267 .
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-
ing if:
- the t ire pressure in one or more tires is too low
- the tire has structural damage
- the tire was replaced or the tire pressure was
changed and it was not stored

- If the tire pressure ind icator appears in the
display, reduce your speed imm ediately and
avoid any hard steering or braking maneu-
vers. Stop as soon as possible and check the
