Jeep 2008 Commander - Manual (Page 329)

The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• 4 Tire Pressure Monitoring Sensors
• 3 Trigger Modules (mounted in three of the four wheel
wells)
• Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC), and a graphic displaying tire pressures
• Tire Pressure Monitoring Telltale Light
A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size
spare tire can be used in place of any of the four road
tires. A low spare tire will set the “SPARE LOW PRES-
SURE” textual message, but it will not cause the “Tire
Pressure Monitoring Telltale Light” to illuminate or the
chime to sound.
Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an au-
dible chime will be activated when one or more of
the four active road tire pressures are low. In addition, the
Electronic Vehicle Information Center (EVIC) will display
one or more Low Pressure messages (Left Front, Left
Rear, Right Front, Right Rear) for 3 seconds, and a
graphic display of the pressure value(s) with the low
tire(s) flashing. Refer to “Electronic Vehicle Information
Center (EVIC)” in Section 4 of this manual.
