2007 JEEP PATRIOT TPMS

vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a signifi-
cantly 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.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver 's responsibility tomaintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
The Tire Pressure Monitoring Telltale Lamp will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more tire pressures is low. The
Tire Pressure Monitoring Telltale Lamp will flash on and
off for 60 seconds when a system fault is detected. The
flash cycle will repeat every ten minutes or until the fault
condition is removed and reset.

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 opera-
tion or sensor damage may result when using re-
placement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result.
23. Four-Wheel-Drive Light
This light indicates the vehicle is in 4WD locked mode.
24. Odometer/Trip Odometer
A vacuum fluorescent display indicates the total distance
the vehicle has been driven. Also, the cluster will display,replacing the odometer/trip odometer, vehicle warning
messages such as: door/gate ajar and loose gas cap.
Loose gas cap will be displayed from the Odometer/Trip
Odometer on all models.
NOTE:If vehicle is equipped with the optional Elec-
tronic Vehicle Information Center (EVIC) in the instru-
ment cluster, all warnings including ªdoorº, and ªgATEº
will only be displayed in the EVIC display. For additional
information, refer to ªElectronic Vehicle Information Cen-
ter Ð If Equippedº in Section 3.
U.S. federal regulations require that upon transfer of
vehicle ownership, the seller certify to the purchaser the
correct mileage that the vehicle has been driven. There-
fore, if the odometer reading is changed during repair or
replacement, be sure to keep a record of the reading
before and after the service so that the correct mileage can
be determined.

Distance To Empty (DTE)
Shows the estimated distance that can be travelled with
the fuel remaining in the tank. This estimated distance is
determined by a weighted average of the instantaneous
and average fuel economy, according to the current fuel
tank level. This is not resettable.
NOTE:Significant changes in driving style or vehicle
loading will greatly affect the actual drivable distance of
the vehicle, regardless of the DTE displayed value.
When the DTE value is less than 30 miles estimated
driving distance, the DTE display will change to a text
display of9LOW FUEL9. This display will continue until
the vehicle runs out of fuel. Adding a significant amount
of fuel to the vehicle will turn off the9LOW FUEL9text
and a new DTE value will be displayed, based on the
current values in the DTE calculation and the current fuel
tank level.
Elapsed Time
Shows the total elapsed time of travel since the last reset
when the ignition switch is in the ACC position. Elapsed
time will increment when the ignition switch is in the ON
or START position.
Tire Pressure Monitor (TPM)
Refer to Section 5, ªTire Pressure Monitoring System
(TPMS) for system operation.
Personal Settings (Customer Programmable
Features)
This allows the driver to set and recall features when the
transmission is in PARK (automatic transmission) or the
vehicle is stopped (manual transmissions).
Press and release the EVIC button until Personal Settings
is displayed in the EVIC.
Use the EVIC button to display one of the following

CAUTION!
Replacing original tires with tires of a different size
may result in false speedometer and odometer
readings.
Alignment And Balance
Poor suspension alignment may result in:
²Fast tire wear.
²Uneven tire wear, such as feathering and one-sided
wear.
²Vehicle pull to right or left.
Tires may also cause the vehicle to pull to the left or right.
Alignment will not correct this condition. See your dealer
for proper diagnosis.Improper alignment will not cause vehicle vibration.
Vibration may be a result of tire and wheel out-of-
balance. Proper balancing will reduce vibration and
avoid tire cupping and spotty wear.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
Ð IF EQUIPPED
Base Tire Pressure Monitoring System (TPMS)
Operation ± If Equipped
This is the Tire Pressure Monitoring System warn-
ing indicator located in the instrument cluster.
²The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
²The tire pressure will vary with temperature by about
1 psi (6.9 kPa) for every 12 ÉF (6.5 ÉC). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
294 STARTING AND OPERATING

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.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and to maintain
the proper pressure.
The TPMS consists of the following components:
²Receiver Module
²4 Tire Pressure Monitoring Sensors
²3 Trigger Modules (mounted in three of the four wheel
wells)
²Various Tire Pressure Monitoring System Messages,
which display in the Electronic Vehicle Information
Center (EVIC)
²Yellow Tire Pressure Monitoring Telltale Light
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Lamp will illumi-
nate in the instrument cluster, and an audible chime will
be activated when one or more of the four active road tire
pressures are low. The audible chime will sound once
every ignition cycle for each condition that it detects. In
addition, the Electronic Vehicle Information Center
(EVIC) will display a graphic of the pressure value(s)
with the low tire(s) flashing.
296 STARTING AND OPERATING

Display Settings
²Your system can be set to display pressure units in PSI,
kPa, or BAR.
NOTE:These display settings may not be available due
to Regulatory Authorities. In this case, the display will
only show approved units.
NOTE:If your vehicle is equipped with a compact spare
wheel and tire assembly that does not have a tire pressure
monitoring sensor. Therefore, it will not be monitored by
the Tire Pressure Monitor System (TPMS). In the event
that the compact spare tire is swapped with a low
pressure road tire, the next ignition key cycle will still
show the ªTire Pressure Monitoring Lampº to be ON, a
chime to sound, and the Electronic Vehicle Information
Center (EVIC) will still show the low tire pressure value
flashing on the graphic display. However, driving the
vehicle for up to 10 minutes above 15 mph (25 km/h) will
display a ªCHECK TPM SYSTEMº text message on theEVIC. This text message will then be followed by a
graphic, with ª- -ª in place of the flashing low pressure
value. For every subsequent key cycle, the ªTire Pressure
Monitoring Lampº will be ON, a chime will sound, a
ªCHECK TPM SYSTEMº text message will be display in
the EVIC, and the graphic display will have ª- -ª in place
of the pressure value of the spare tire location. Once the
original road tire has been properly repaired, and put
back onto the vehicle in place of the compact spare tire.
The TPMS will update the graphic display on the EVIC
with a new tire pressure value instead of ª- -ª, and the
ªTire Pressure Monitoring Lampº will be OFF as long as
none of the road tire(s) are below the low pressure
warning threshold. The vehicle may need to be driven for
up to 10 minutes above 15 mph (25 km/h) to receive this
information.

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures have
been established for the tire size equipped on your
vehicle. Undesirable system operation or sensor
damage may result when using replacement equip-
ment that is not of the same size, type, and/or style.
Aftermarket wheels can cause sensor damage. Do not
use tire sealant from a can, or balance beads if your
vehicle is equipped with a TPMS, as damage to the
sensors may result.
CAUTION!
After inspecting or adjusting the tire pressure, al-
ways reinstall the valve stem cap. This will prevent
moisture and dirt from entering the valve stem,
which could damage the wheel rim sensor.
NOTE:
²The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
²The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
²Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
