Tire Pressure Monitor System
The Tire Pressure Monitor (TPM) System on your vehicle,
uses radio and sensor technology to check tire pressure
levels. Sensors, mounted on each tire and wheel
assembly transmit tire pressure readings to a receiver
located in the vehicle. The TPM sensors transmit tire
pressure readings once every 60 seconds while the
vehicle is being driven and once every 60 minutes when
the vehicle is stationary for more than 15 minutes. Using
the Driver Information Center (DIC), tire pressure levels
can be viewed by the driver. The TPM system also uses
the DIC to warn the driver when air pressure, in one or
more tires, falls below 24 psi (164 kPa) or is above 42 psi
(290 kPa). For additional information and details about
the DIC operation and displays see DIC Controls and
Displays on page 3-48 and DIC Warnings and Messages
on page 3-53.
A low tire pressure warning light also appears on the
instrument panel cluster when a low tire condition exists.
The low tire pressure warning light will be shown
each time the engine is started and stay on until the low
tire condition is corrected.
When the tire pressure
monitoring system warning
light is lit, one or more
of your tires is significantly
under-inflated.
You should stop and check your tires as soon as
possible, and inflate them to the proper pressure as
indicated on the vehicle’s tire information placard.
Driving on a significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling and stopping
ability. Each tire, including the spare, should be
checked monthly when cold and set to the
recommended inflation pressure as specified in the
vehicle placard and owner’s manual.
The Tire and Loading Information Label (tire information
placard) is on the rear edge of the driver’s door,
below the door latch. This label shows the size of your
vehicle’s original tires and the correct inflation
pressure for your vehicle’s tires when they are cold. See
Loading Your Vehicle on page 4-32.
