SAFETY 279
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
equipped with Tire Fill Alert.

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 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 system only warns the tire pressure is low:
it is not able to inflate them.
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 regularly check
the tire pressure in all of your tires and to maintain
the proper pressure.
The Tire Pressure Monitoring System (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, and a graphic displaying tire pressures

TPMS Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate in
the instrument cluster, and an audible
chime will be activated when one or more
of the four active road tire pressures are
low. In addition, the instrument cluster will display
a "Tire Low" message and a graphic display of the
pressure value(s) with the low tire(s) in a different
color

NOTE:
Your system can be set to display pressure units in
PSI, BAR, or kPa.
