NOTE:
• The TPMS is not intended to replace nor-
mal tire care and maintenance, or to pro-
vide 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 under-inflated
tire causes the tire to overheat and can
lead to tire failure. Under-inflation 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
responsibility to maintain correct tire
pressure using an accurate tire gauge,
even if under-inflation has not reached
the level to trigger illumination of the Tire
Pressure Monitoring Telltale 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 Monitor System (TPMS)
uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pres-
sure 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 regu-
larly check the tire pressure in all of your
tires and to maintain the proper pressure.
The Tire Pressure Monitor System (TPMS) con-
sists of the following components:
1. Receiver Module
2. Four Tire Pressure Monitoring Sensors
3. Various Tire Pressure Monitoring System
Messages, which display in the Electronic Ve-
hicle Information Center (EVIC), and a graphic
displaying tire pressures
4. Tire Pressure Monitoring Telltale Light

Tire Pressure Monitoring Low
Pressure Warnings
The Tire Pressure Monitoring Telltale
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 addi-
tion, the EVIC will display one or more Low
Pressure messages (Left Front, Left Rear, Right
Front, Right Rear) for a minimum of five sec-
onds, and a graphic display of the pressure
value(s) with the low tire(s) "flashing." Refer to
"Electronic Vehicle Information Center (EVIC)"
in "Understanding Your Instrument Panel" for
further information.
NOTE:
Your system can be set to display pressure
units in PSI, kPa, or BAR.
