Jeep 2013 Wrangler - Owner Manual - Manual (Page 507)

The Tire Pressure Monitor System (TPMS) consists of the
following components:
• Receiver Module
• Four Tire Pressure Monitoring Sensors
• 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 not cause the “Tire Pressure
Monitoring Telltale Light” to illuminate or the chime to
sound.
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, , a “LOW
TIRE PRESSURE” message will display in the
EVIC, 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
placard pressure value. The system will automatically
update and the “Tire Pressure Monitoring Telltale Light”
will extinguish once the updated tire pressures have been
received. The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive this
information.
