162 SAFETY
System Operation
The Tire Pressure Monitoring System (TPMS)
uses wireless technology with wheel rim
mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire
pressure readings to the receiver module.
Tire Pressure Monitoring Display
NOTE:
It is particularly important for you to check the
tire pressure in all of the tires on your vehicle
monthly and to maintain the proper pressure.
The TPMS consists of the following compo-
nents:
Receiver module
Four Tire Pressure Monitoring sensors
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster
Tire Pressure Monitoring warning light
Tire Pressure Monitoring Low Pressure
Warnings
The TPMS Warning Light will illumi-
nate in the instrument cluster and a
chime will sound when tire pressure is
low in one or more of the four active road tires.
In addition, the instrument cluster will display a
"Tire Low" message for a minimum of five
seconds, an "Inflate to XX" message and a
graphic showing the pressure values of each
tire with the low tire pressure values in a
different color.
Tire Pressure Monitoring Low Pressure Warning
Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those in a different color in the instrument
cluster graphic) to the vehicle’s recommended
cold placard pressure value as shown in the
"Inflate to XX" message. Once the system
receives the updated tire pressures, the system
will automatically update, the pressure values
in the graphic display in the instrument cluster
will return to their original color, and the TPMS
Warning Light will turn off.
NOTE:
When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi
(28 kPa) above the recommended cold placard
pressure in order to turn the TPMS Warning
Light off.
