• Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion 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 mainte-
nance, and it is the driver’s responsibility 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.
Base 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 components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, a “LOW TIRE
PRESSURE” message will display in the instrument cluster,
an ⬙Inflate to XX⬙ message will be displayed and a chime
will sound when tire pressure is low in one or more of the
four active road tires. Should this occur, you should stop as
soon as possible, check the inflation pressure of each tire on
your vehicle, and inflate each tire 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 pressures, the system will automatically up-
date and the “Tire Pressure Monitoring Telltale Light” will
turn off.
