2010 JEEP GRAND CHEROKEE TPMS

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 willsound, 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.

STARTING AND OPERATING 309

NOTE:It is particularly important, for you to regularly
check the tire pressure in all of your tires and to maintain
the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Three Trigger Modules (mounted in three of the four
wheel wells)
•Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC), and a graphic displaying tire pressures
•Tire Pressure Monitoring Telltale Light A tire pressure monitoring sensor is located in the spare
wheel, if the vehicle is equipped with a matching full-size
spare wheel and tire assembly. The matching full-size
spare tire can be used in place of any of the four road
tires. A low spare tire will set the “SPARE LOW PRES-
SURE” message, but it will not cause the Tire Pressure
Monitoring Telltale Light to illuminate or the chime to
sound.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will
illuminate in the instrument cluster, and an au-
dible chime will be activated, when one or more of
the four active road tire pressures are low. In addition, the
EVIC will display one or more Low Pressure messages
(Left Front, Left Rear, Right Front, Right Rear) for three
seconds, and a graphic display of the pressure value(s)
with the low tire(s) “flashing.” Refer to “Electronic Ve-
hicle Information Center (EVIC)” in “Understanding
Your Instrument Panel” for further information.

case, theCHECK TPM SYSTEM message is then fol-
lowed by a graphic display, with pressure values still
shown. This indicates the pressure values are still being
received from the TPM Sensors. However, the system still
needs to be serviced as long as the CHECK TPM
SYSTEM message exists.
NOTE:
•If your vehicle is equipped with a matching full-size
spare wheel and tire assembly, it has a tire pressure
monitoring sensor, and can be monitored by the Tire
Pressure Monitoring System (TPMS). In the event that
the matching full-size spare tire is swapped with a low
pressure road tire, the next ignition switch cycle will
still show the Tire Pressure Monitoring Telltale Light
to be ON, a chime to sound, a Low Pressure message
to appear in the EVIC, and the graphic display will
still show the low tire pressure value “flashing.”
Driving the vehicle for up to 20 minutes above 15 mph
(24 km/h) will turn OFF the Tire Pressure Monitoring Telltale Light as long as none of road tires are below
the low pressure warning threshold. The EVIC will
also display a “SPARE LOW PRESSURE” message,
and the graphic display will show a tire pressure value
in place of the “flashing” low tire pressure value.
•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, the Tire Pressure
Monitoring Telltale Light will remain ON, a chime will
sound, and the EVIC will still display a “flashing”
pressure value in the graphic display. 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 “CHECK TPM

SYSTEMmessage 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 CHECK TPM SYSTEM
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.General Information
