Wheels
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi-
cantly under-inflated
tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
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 System
indicator appears
Applies to: vehicles with Tire Pressure Monito ring System
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. 206 Instrument cluster: indicator ligh t 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 indicated in the instrument cluster
display with an indicator light
IE
and a message
c> fig.
206. If only one tire is affected, the loca-
tion 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

page 249.
The tire pressure moni-
toring system only monitors the tire pressure you
have stored. Refer to the tire pressure label for
the recommended tire pressure for your vehicle

page 240, fig. 205.
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 tire has structural damage.
- the tire was replaced or the tire pressure was
changed and it was not stored
