• 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 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 your tires regularly and to maintain the
proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Tire Pressure Warnings
The TPMS Warning Light will illuminate in the
instrument cluster, a "LOW TIRE PRESSURE"
message will display in the instrument cluster,
and an audible chime will be activated when one
or more of the four active road tire pressures are low.
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 recommended cold tire
placard pressure value (located on the placard label on the
driver's-side B-Pillar).
NOTE: When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in order to
turn the TPMS Warning Light off.
The system will automatically update and the TPMS
Warning Light will extinguish once the updated tire pres-
sures have been received.
NOTE: The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this informa-
tion.
