Jeep 2014 Grand Cherokee SRT - Owner Manual - Manual (Page 451)

NOTE:
• There is no tire pressure monitoring sensor in the spare
tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road
tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, the Tire
Pressure Monitoring Telltale Light will remain ON, a
chime will sound, and the EVIC will still display a
“flashing” or different color pressure value in the
graphic display. An
ЉInflate to XXXЉ message will still
be displayed.
• After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid. In addition, the EVIC will
display a “SERVICE TPM SYSTEM
Љ message for three
seconds and then display dashes (- -) in place of the
pressure value. For each subsequent ignition switch
cycle, a chime will sound, the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid, and the EVIC will display a
ЉSERVICE TPM SYSTEMЉ message for three seconds
and then display dashes (- -) in place of the pressure
value. Once you repair or replace the original road tire,
and reinstall it on the vehicle in place of the spare tire,
the TPMS will update automatically.
In addition, the Tire Pressure Monitoring Telltale Light
will turn OFF and the graphic in the EVIC will display a
new pressure value instead of dashes (- -), as long as no
tire pressure is below the low-pressure warning limit in
any of the four active road tires. The vehicle may need to
be driven for up to 20 minutes above 15 mph (24 km/h)
in order for the TPMS to receive this information.
