sensor JEEP LIBERTY 2008 KK / 2.G Owner's Manual

will sound when tire pressure is low in one or more of the
four active road tires. In addition, the Electronic Vehicle
Information Center (EVIC) will display a graphic show-
ing the pressure values of each tire with the low tire
pressure values flashing.Should this occur, you should stop as soon as possible,
and inflate the tires with low pressure (those flashing in
the EVIC graphic) to the vehicle's recommended cold
placard pressure value. Once the system receives the
updated tire pressures, the system will automatically
update, the graphic display in the EVIC will stop flash-
ing, and the Tire Pressure Monitoring Telltale Light will
turn off. The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) in order for the TPMS
to receive this information.
Check TPMS Warning
When a system fault is detected, the Tire Pressure Moni-
toring Telltale Light will flash on and off for 75 seconds
and then remain on solid. The system fault will also
sound a chime. In addition, the EVIC will display a
9CHECK TPM SYSTEM9message for 3 seconds and then
display dashes (- -) in place of the pressure value to
indicate which sensor is not being received.
352 STARTING AND OPERATING

If the ignition key is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault
no longer exists, the Tire Pressure Monitoring Telltale
Light will no longer flash, and the9CHECK TPM SYS-
TEM9message will no longer display, and a pressure
value will display in place of the dashes. A system fault
can occur due to any of the following:1. Jamming due to electronic devices or driving next to
facilities emitting the same Radio Frequencies as the TPM
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
3. Lots of snow or ice around the wheels or wheel
housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
Vehicles with Full Size Spare
1. The matching full size spare wheel and tire assembly
has a tire pressure monitoring sensor that can be moni-
tored by the TPMS.
2. If you install the full size spare in place of a road tire
that has a pressure below the low-pressure warning limit,
STARTING AND OPERATING 353

upon the next ignition key cycle, a chime will sound and
the TPM Telltale Light will turn ON. In addition, the
EVIC will display a Low Pressure message and a graphic
showing the low tire pressure value flashing.
3. After driving the vehicle for up to 10 minutes above 15
mph (25 km/h) the TPM Telltale Light will turn OFF, as
long as no tire pressure is below the low-pressure warn-
ing limit in any of the four active road tires.
4. The EVIC will display a graphic showing the tire
pressure value in place of the flashing low tire pressure
value. The EVIC will also display a ªSPARE LOW
PRESSUREº message to remind you to service the flat
tire.
NOTE:
Vehicles with Compact Spare
1. The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not monitor
the pressure in the compact spare tire.2. If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warning
limit, upon the next ignition key cycle, the TPM Telltale
Light will remain ON and a chime will sound. In
addition, the graphic in the EVIC will still display a
flashing pressure value.
3. After driving the vehicle for up to 10 minutes above 15
mph (25 km/h), the TPM Telltale Light will flash on and
off for 75 seconds and then remain on solid. In addition,
the EVIC will display a9CHECK TPM SYSTEM9message
for 3 seconds and then display dashes (- -) in place of the
pressure value.
4. For each subsequent ignition key cycle, a chime will
sound, the TPM Telltale Light will flash on and off for 75
seconds and then remain on solid, and the EVIC will
display a9CHECK TPM SYSTEM9message for 3 seconds
and then display dashes (- -) in place of the pressure
value.
354 STARTING AND OPERATING

5. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
TPM 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 10 minutes above
15 mph (25 km/h) in order for the TPMS to receive this
information.
