Tire Pressure Monitor
Operation
The Tire Pressure Monitor System
(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 monitor the air
pressure in the vehicle’s tires and
transmit the tire pressure readings to
a receiver located in the vehicle.
When a low tire pressure condition is
detected, the TPMS turns on the
7
low tire pressure warning light.
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 4-23 and DIC
Warnings and Messages on
page 4-27.
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.
A Tire and Loading Information label
shows the size of the vehicle’s
original equipment tires and
the correct inflation pressure for the
vehicle’s tires when they are
cold. See Loading the Vehicle on
page 8-28, for an example of
the Tire and Loading Information
label and its location on the vehicle.
