Service Tpm System Warning - Jeep Grand Cherokee 2014 Operating Manual

NOTE:
Your system can be set to display pressure
units in PSI or kPa.
Should a low tire condition occur on any of the
four active road tire(s), you should stop as soon
as possible, and inflate the low tire(s) that is in
a different color on the graphic display to the
vehicle's recommended cold tire pressure dis-
played in the "Inflate Tire to XXX" message. The
system will automatically update, the graphic
252
display of the pressure value(s) will return to its
original color and the Tire Pressure Monitoring
Telltale Light will extinguish once the updated
tire pressure(s) have been received. The ve-
hicle may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this infor-
mation.

SERVICE TPM SYSTEM Warning

The Tire Pressure Monitoring Telltale 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. The EVIC
will display a "SERVICE TPM SYSTEM" mes-
sage for a minimum of five seconds. This mes-
sage is then followed by a graphic display, with
"- -" in place of the pressure value(s), indicating
which Tire Pressure Monitoring Sensor(s) is not
being received.
NOTE:
Your system can be set to display pressure
units in PSI or kPa.
If the ignition switch is cycled, this sequence will
repeat, providing the system fault still exists. If
the system fault no longer exists, the Tire Pres-
sure Monitoring Telltale Light will no longer
flash, the "SERVICE TPM SYSTEM" message
will not be present, and a pressure value will be
displayed instead of dashes. A system fault can
occur by any of the following:
1. Jamming due to electronic devices or driving
next to facilities emitting the same Radio Fre-
quencies as the TPM sensors.
2. Installing some form of aftermarket window
tinting that affects radio wave signals.
