166 SAFETY
NOTE:
The TPMS is not intended to replace normal

tire care and maintenance, or to provide
warning of a tire failure or condition.
The TPMS should not be used as a tire pres-

sure gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire

causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle's handling and stopping ability.
The TPMS is not a substitute for proper tire

maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure using an
accurate tire pressure gauge, even if underin-
flation has not reached the level to trigger illu-
mination of the TPMS Warning Light.
Seasonal temperature changes will affect

tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
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
components:
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
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 "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.
