System Operation
The Tire Pressure Monitor System (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 Tire Pressure Monitor System (TPMS) con-
sists 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 illu-
minate in the instrument cluster , a
“LOW TIRE PRESSURE” mes-
sage 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 recom-
mended cold tire placard pressure value (lo-
cated 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 pressures 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 information.
Service Tpm System
The TPMS Warning Light will flash on and off for
75 seconds, and remain on solid when a system
fault is detected. The system fault will also
sound a chime. If the ignition switch is cycled,
this sequence will repeat, providing the system
fault still exists. The TPMS W arning Light will
turn off when the fault condition no longer
exists. A system fault can occur with any of the
following scenarios:
• Jamming due to electronic devices or driving
next to facilities emitting the same radio fre-
quencies as the TPMS sensors.
• Installing some form of aftermarket window
tinting that affects radio wave signals.
• Accumulation of excessive snow and/or ice
around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPMS
sensors.
Vehicles With Compact Spare
•
The compact spare tire (if equipped) does not
have a TPMS sensor . Therefore the TPMS will not
monitor the pressure in the compact spare tire.
