118 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
underinflation has not reached the level to
trigger illumination of the Tire Pressure Moni-
toring System Warning Light.
Seasonal temperature changes will affect
tire pressure, and the TPMS will monitor the
actual tire pressure in the tire.
Premium System
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.
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 will display in the instru-
ment cluster display.
Tire Pressure Monitoring System Warning
Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring System
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, an “Inflate to XX” message, and a
graphic showing the pressure values of each
tire with the low tire pressure values highlighted
or in a different color.
Tire Pressure Monitoring Low Pressure Warning
Should this occur, you should stop as soon as
possible and inflate the tires with low pressure
(those highlighted or in a different color in the
instrument cluster display 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 stop being
highlighted or return to their original color, and
the Tire Pressure Monitoring System Warning
Light will turn off.
