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 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 respon-
sibility 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 pressure, and the TPMS will monitor
the actual tire pressure in the tire.
System Operation
The Tire Pressure Monitor 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 telltale light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Warning Light will illumi-
nate 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.
