• The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s respon-
sibility to maintain correct tire pressure
using an accurate tire gauge, even if under-
inflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring
Telltale Light.
• Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor
the actual tire pressure in the tire.
The Tire Pressure Monitor 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.
NOTE:
It is particularly important, for you to regu-
larly check the tire pressure in all of your tires
and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS)
consists of the following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Various Tire Pressure Monitoring System
Messages, which display in the instrument
cluster, and a graphic displaying tire pres-
sures
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring Telltale
Light will illuminate in the instru-
ment cluster, and an audible chime
will be activated, when one or more of the
four active road tire pressures are low. In
addition, the instrument cluster will display
an "Inflate to XX" message and a graphic
display of the pressure value(s) with the low
tire(s) in a different color. Refer to “Instru-
ment Cluster Display” in “Getting To Know
Your Instrument Panel” for further informa-
tion.
