158 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 pressure
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 effi-
ciency 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 responsibility
to maintain correct tire pressure using an accu-
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
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 Ú page 273.
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 System sensors.
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster.
Tire Pressure Monitoring System Warning Light.
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
(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 an “Inflate to XX”
message and a graphic showing the pressure
values of each tire with the low tire pressure values
shown in a different color.
