CAUTION! (Continued)
After inspecting or adjusting the tire

pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which
could damage the TPMS sensor.
NOTE:
The TPMS is not intended to replace

normal tire care and maintenance, or to
provide warning of a tire failure or condi-
tion.
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
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 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 compo-
nents:
Receiver module

Four Tire Pressure Monitoring sensors

Various Tire Pressure Monitoring System

messages, which display in the instrument
cluster
Tire Pressure Monitoring System Warning

Light
Tire Pressure Monitoring Low Pressure Warnings
The "Tire Pressure
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 and a graphic showing the pressure
values of each tire with the low tire pressure
values in a different color.
