• 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 “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
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 Warn-
ings
The “Tire Pressure Monitoring Tell-
tale Light” will illuminate in the in-
strument 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,
an "Inflate to XX" message and a graphic
showing the pressure values of each tire with
the low tire pressure values in a different
color.
Should this occur, you should stop as soon as
possible and inflate the tires with low pres-
sure (those in a different color in the instru-
ment cluster graphic) to the vehicle’s recom-
mended cold placard pressure value as
shown in the "Inflate to XX" message. Once
the system receives the updated tire pres-
