Premium System - If Equipped - Jeep 2010 Grand Cherokee Owner's Manual

Tire Pressure Monitoring Telltale Light as long as none
of the road tires are below the low pressure warning
threshold.
• If your vehicle is not equipped with a matching
full-size spare wheel and tire assembly, it does not
have a 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, a chime will
sound, a "TIRE LOW PRESSURE" message will be
displayed in the instrument cluster for 60 seconds, and
the Tire Pressure Monitoring Telltale Light will turn
ON. After driving the vehicle for up to 20 minutes
above 15 mph (25 km/h), the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid. In addition, a "CHECK TPM
SYSTEM" message will be displayed for 75 seconds.
For each subsequent ignition switch cycle, a chime will
sound, a "CHECK TPM SYSTEM" message will be
displayed for 75 seconds, and the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75 seconds
and then remain on solid. 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 automati-
cally and the Tire Pressure Monitoring Telltale Light
will turn OFF, 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.
Premium System – If Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim-mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the Receiver Module.
