General Information - Jeep grand cherokee 2015 Owner's Manual

526 STARTING AND OPERATING
However, the system still needs to be serviced as long as
the SERVICE TPM SYSTEM message exists.
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 warning limit,
upon the next ignition switch cycle, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the DID will still display a pressure value in the
different color graphic display and an Inflate to XXX kPa
message will 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 DID will
display a "SERVICE TPM SYSTEM message for five
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 DID will display a SERVICE TPM
SYSTEM message for five 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 DID 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.
