2009 DODGE JOURNEY TPMS

21. Tire Pressure Monitoring Telltale Light — If
EquippedEach tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
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 light illuminates,
you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to over-
heat 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 to
maintain correct tire pressure, even if under-inflation has
not reached the level to trigger illumination of the TPMS
low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is not
operating properly. The TPMS malfunction indicator is
combined with the low tire pressure telltale. When the
system detects a malfunction, the telltale will flash for
approximately one minute and then remain continuously
illuminated. This sequence will continue upon subse-
quent vehicle start-ups as long as the malfunction exists.

When the malfunction indicator is illuminated, the sys-
tem may not be able to detect or signal low tire pressure
as intended. TPMS malfunctions may occur for a variety
of reasons, including the installation of replacement or
alternate tires or wheels on the vehicle that prevent the
TPMS from functioning properly. Always check the
TPMS malfunction telltale light after replacing one or
more tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow the TPMS
to continue to function properly. (See page 355 for more
information.)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 aftermarket tire sealants
or balance beads if your vehicle is equipped with a
TPMS, as damage to the sensors may result. (Refer to
“Tire Inflation Pressures” under “Tires — General
Information” and to “Tire Pressure Monitor System
(TPMS)” in Section 5 for more information).

TIRE CHAINS
Due to limited clearance, tire chains are not recommended.
CAUTION!
Damage to the vehicle may result if tire chains are used.
SNOW TIRES
Some areas of the country require the use of snow tires
during the winter. Standard tires are of the all season type
and satisfy this requirement as indicated by the M+S
designation on the tire sidewall.
If you need snow tires, select tires equivalent in size and
type to the original equipment tires. Use snow tires only
in sets of four. Failure to do so may adversely affect the
safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what
was originally equipped with your vehicle and shouldnot be operated at sustained speeds over 75 mph (120
km/h).
TIRE PRESSURE MONITOR SYSTEM (TPMS) — IF
EQUIPPED
•
The Tire Pressure Monitor System (TPMS) will warn
the driver of a low tire pressure based on the vehicle
recommended cold placard pressure.
•The tire pressure will vary with temperature by about 1
psi (6.9 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mi (1 km)
after a three hour period. The cold tire inflation pressure
must not exceed the maximum inflation pressure
molded into the tire sidewall. Refer to the “Tires –
General Information” in this section for information on

how to properly inflate the vehicle’s tires. The tire
pressure will also increase as the vehicle is driven. This
is normal and there should be no adjustment for this
increased pressure.
•The TPMS will warn the driver of a low tire pressure
if the tire pressure falls below the low-pressure warn-
ing limit for any reason, including low temperature
effects and natural pressure loss through the tire.
•The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recom-
mended cold placard pressure. Once the low tire pres-
sure warning (Tire Pressure Monitoring Telltale light)
illuminates, you must increase the tire pressure to the
recommended cold placard pressure in order for the Tire
Pressure Monitoring Telltale light to turn off. The system
will automatically update and the Tire Pressure Moni-
toring Telltale light will turn off once the system re-
ceivesthe updated tire pressures. 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.
For example, your vehicle may have a recom-
mended 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 ap-
proximately 24 psi (165 kPa). This tire pressure is
low enough to turn ON the Tire Pressure Monitor-
ing 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.
356 STARTING AND OPERATING

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.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 Moni-
toring Telltale light.

•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base 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 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
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 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. If the ignition key is cycled, this sequence
