NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, nor to provide 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. Underin-
flation 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, 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.
Tire Pressure Monitor System Components
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. 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 your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
• Receiver Module
• Four Wheel Sensors
• Tire Pressure Monitoring Telltale Lamp
