or tire inflation pressure label, you should
d
e
termine the proper tire inflation pressure for
those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates alow tire
pressure telltale when one or more of your tires
is significantly under-inflated.
Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your
tires as soon as possible, and inflate them to
the proper pressure. Driving on asignificantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces energy efficiency and tire tread
life, and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate when
the system is not operating properly. The TPMS
malfunction indicator is combined with the
low tire pressure telltale. When the system
detects a malfunction, the telltale will flash for
a
pproximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction 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.

Tire Pressure Monitor Operation
This vehicle may have aTire Pressure Monitor
System (TPMS). The TPMS is designed to warn
the driver when alow tire pressure condition
exists. TPMS sensors are mounted onto each
tire and wheel assembly, excluding the spare
tire and wheel assembly. The TPMS sensors
mo
nitor the air pressure in the tires and
transmit the tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition is detected,
t
he TPMS illuminates the low tire pressure
warning light located on the instrument
cluster. If the warning light comes on, stop
as soon as possible and inflate the tires to the
recommended pressure shown on the Tire and
Loading Information label. See Vehicle Load
Limits 3179.
A message to check the pressure in aspecific
tire displays in the Driver Information Center
(DIC). The low tire pressure warning light and
the DIC warning message come on each time
the vehicle is started until the tires are inflated
to the correct inflation pressure. If the vehicle
has DIC buttons, tire pressure levels can be
viewed. For additional information and details
about the DIC operation and displays, see Driver
Information Center (DIC) 3115.
