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,
if the vehicle has one. The TPMS
sensors monitor the air pressure in
the vehicle’s tires and transmits
the tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition is
detected, the TPMS illuminates the
low tire pressure warning light
located on the instrument panel
cluster.
At the same time a message to
check the pressure in a specific tire
appears on the Driver Information
Center (DIC) display. The low
tire pressure warning light and the
DIC warning message come on
at each ignition cycle until the tires
are inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed by
the driver. For additional information
and details about the DIC operation
and displays see DIC Operation
and Displays on page 3-43 and DIC
Warnings and Messages on
page 3-50.
The low tire pressure warning light
may come on in cool weather
when the vehicle is first started, and
then turn off as you start to drive.
This could be an early indicator that
the air pressure in the tire(s) are
getting low and need to be inflated
to the proper pressure.
