2010 JEEP LIBERTY warning light

For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pressure
of 33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi (193 kPa),
a temperature drop to 20°F (-7°C) will decrease the tire
pressure to approximately 24 psi (165 kPa). This tire
pressure is low enough to turn ON the “Tire Pressure
Monitoring Telltale Light.” Driving the vehicle may cause
the tire pressure to rise to approximately 28 psi (193 kPa),
but the “Tire Pressure Monitoring Telltale Light” will still
be on. In this situation, the “Tire Pressure Monitoring
Telltale Light” will turn off only after the tires are inflated
to the vehicle’s recommended cold placard pressure
value.CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when us-
ing replacement equipment that is not of the same
size, type, and/or style. Aftermarket wheels can
cause sensor damage. Do not use aftermarket tire
sealants or balance beads if your vehicle is
equipped with a TPMS, as damage to the sensors
may result.
•After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure Moni-
toring Sensor.
364 STARTING AND OPERATING

NOTE:
•The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
•The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
•Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if under-inflation has not reached the
level to trigger illumination of the “Tire Pressure
Monitoring Telltale Light.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
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.
NOTE:It is particularly important for you to check the
tire pressure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•Tire Pressure Monitoring Telltale Light

STARTING AND OPERATING 365

The matching full-size spare wheel and tire assembly (if
equipped) has a tire pressure monitoring sensor. The
matching full-size spare can be used in place of any of the
four road tires. The TPMS will only monitor the pressure
in the full-size spare when it is used in place of a road
tire. Otherwise, a spare with a pressure below the low-
pressure limit will not cause the “Tire Pressure Monitor-
ing 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 a chime
will sound when tire pressure is low in one or
more of the four active road tires. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each tire
to the vehicle’s recommended cold placard pressure
value. Once the system receives the updated tire pres-
sures, the system will automatically update and the “Tire
Pressure Monitoring Telltale Light” will turn off. The vehicle may need to be driven for up to 20 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
Monitoring Telltale Light” will flash on and off for
75 seconds and then remain on solid. The system fault
will also sound a chime. If the ignition key is cycled, this
sequence will repeat, providing the system fault still
exists. The “Tire Pressure Monitoring Telltale Light” will
turn off when the fault condition no longer exists. 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 TPMS
sensors.
2. Installing some form of aftermarket window tinting
that affects radio wave signals.
366 STARTING AND OPERATING

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 TPMS sensors.
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,
a chime will sound and the “TPMS Telltale Light” will
turn on upon the next ignition key cycle.
3. Driving the vehicle for up to 20 minutes above 15 mph
(25 km/h) will turn off the “TPMS Telltale Light,” as long
as no tire pressure is below the low-pressure warning
limit in any of the four active road tires.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, a chime will sound and the “TPMS Telltale Light”
will turn on upon the next ignition key cycle.
3. After driving the vehicle for up to 20 minutes above
15 mph (25 km/h), the “TPMS Telltale Light” will flash
on and off for 75 seconds and then remain on solid.
4. For each subsequent ignition key cycle, a chime will
sound and the “TPMS Telltale Light” will flash on and off
for 75 seconds and then remain on solid.
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 and the “TPMS

will cause a “SPARE LOW PRESSURE” message to
display in the EVIC.
368 STARTING AND OPERATING

Tire Pressure Monitoring Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster and a chime
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 showing 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
20 minutes above 15 mph (25 km/h) in order for the

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 aCHECK TPM
SYSTEM message for three seconds and then display
dashes (- -) in place of the pressure value to indicate which
sensor is not being received.
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 the CHECK TPM
SYSTEM message 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 TPMS
