258 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, unless your vehicle
is equipped with a Tire Fill Alert or Selectable Tire Fill
Alert feature.
Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion 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 mainte-
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate 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 pres-
sure, and the TPMS will monitor the actual tire pres-
sure 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 System 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 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 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.
Tire Pressure Monitoring System 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.
