222 SAFETY
• The TPMS is not a substitute for proper tire maintenance,
and it is the driver’s responsibility to maintain correct tire
pressure using an accurate tire pressure gauge, even if
under-inflation has not reached the level to trigger illumi -
nation of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure, and
the TPMS will monitor the actual tire pressure in the tire.
Example: Tire Pressure Monitor Display
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 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 components:
• Receiver module
• Four tire pressure monitoring sensors
• Various tire pressure monitoring system messages, which
display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate 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 graphic showing the pressure values of each tire
with the low tire pressure values in a different color. An
"Inflate to XX" message will also be displayed.
