Jeep 2011 grand cherokee, Owner'S Manual, Page: 556 / 724

Tire Pressure Monitoring Telltale Light will flash on and off
for 75 seconds and then remain on solid, and the EVIC will
display a

⬙
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 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.
