2007 CHRYSLER PACIFICA TPMS

21. Tire Pressure Monitoring Telltale Lamp — If
Equipped
Each 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 underinflated.
Accordingly, when the low tire pressure telltale illumi-
nates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving
on a significantly underinflated tire causes the tire tooverheat and can lead to tire failure. Underinflation also
reduces fuel efficiency and tire tread life, and may affect
the vehicle’s handling and stopping ability.
NOTE:The Tire Pressure Monitoring System (TPMS) is
not a substitute for proper tire maintenance, and it is the
driver ’s responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to trigger
illumination of the Tire Pressure Monitoring System 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 one and
off for 60 seconds when a system fault is detected. The
flash cycle will repeat every ten minutes or until the fault
conditions is removed and reset.

CAUTION!
The Tire Pressure Monitoring System (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 ve-
hicle. Undesirable system operation or sensor dam-
age may result when using replacement 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.
22. Airbag Light
This light turns on and remains on for 6 to 8
seconds as a bulb check when the ignition
switch is first turned ON. If the light is not on
during starting, stays on, or turns on while
driving, have the system inspected by an authorized
dealer as soon as possible.
23. Electronic Vehicle Information Center Display — If
Equipped
When the appropriate conditions exist, this display
shows the Electronic Vehicle Information Center (EVIC)
messages.
24. Engine Temperature Warning Light
This light warns of an overheated engine condi-
tion. If this light is accompanied by a continuous
chime, the engine temperature is critically hot, and
the vehicle should be turned off immediately. The vehicle
should be serviced as soon as possible.

Follow the recommended tire rotation frequency for your
type of driving found in the “Maintenance Schedules”
Section of this manual. More frequent rotation is permis-
sible if desired. The reasons for any rapid or unusual
wear should be corrected prior to rotation being per-
formed.
The suggested rotation method is the “forward-cross”
shown in the following diagram.TIRE PRESSURE MONITOR SYSTEM — IF
EQUIPPED
•
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure. (The
placard is located on the drivers side ”B” Pillar).
•The tire pressure will vary with the 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
pressure will decrease. The tire pressure will also
increase as the vehicle is driven — this is normal and
there should be no adjustment for this increased
pressure.
NOTE:Refer toTires — General Informationin this
section for information on how to properly inflate the
vehicle’s tires.
308 STARTING AND OPERATING

•The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure if the tire
pressure falls below the low pressure warning thresh-
old for any reason, including low temperature effects.
•The Tire Pressure Monitoring System (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 recommended cold placard
pressure. Once the low tire pressure warning telltale
has been illuminated, the tire pressure must be in-
creased to the recommended cold placard pressure in
order for the Tire Pressure Monitoring System warning
telltale to be turned off. The system will automatically
update and the Tire Pressure Monitoring System
warning telltale will extinguish once the updated tire
pressures have been received.
NOTE:
The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this information.
Tire Pressure Monitoring Base System without
Electronic Vehicle Information Center (EVIC) — If
Equipped
The Tire Pressure Monitor System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels (EXCLUDING THE SPARE
TIRE). Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE:It is particularly important, for you to check the
tire pressure in all of your tires regularly and too main-
tain the proper pressure.
The Tire Pressure Monitor System (TPMS) consists of the
following components:
•Receiver Module
•4 Wheel Sensors
•Tire Pressure Monitoring Telltale Lamp

Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Lamp
will illuminate 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 low tire condition that it detects.
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 pressure recommended by the
vehicle tire pressure placard. The system will automati-
cally update and the Tire Pressure Monitoring System
Lamp will extinguish once the updated tire pressure(s)
have been received.
NOTE:The vehicle may need to be driven for up to 10
minutes above 15 mph (25 km/h) to receive this infor-
mation.NOTE:A low spare or compact tire pressure will not
cause the Tire Pressure Monitoring System Telltale Lamp
to illuminate or the chime to sound.

Service Tire System Soon
The Tire Pressure Monitoring Telltale Lamp will flash on
and off for 60 seconds in the instrument cluster, and an
audible chime will be activated when one or more of the
four active road tire pressures are low.
In addition the Electronic Vehicle Information Center
(EVIC) will display a“SERVICE TIRE SYSTEM SOON”
text message. The flash cycle will repeat every ten
minutes, without an audible chime, until the condition no
longer exists. The flash cycle sequence will repeat and an
audible chime will sound once every ignition cycle for
each condition that it detects.
NOTE:If a temporary spare tire is in use and none of
the remaining 3 active road tire pressures are low, a
“SERVICE TIRE SYSTEM SOONtextual message will
appear in the EVIC after 10 minutes of driving,CAUTION!
The Tire Pressure Monitoring System has been op-
timized 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 equipment that is not of the same size,
type, and/or style. After-market wheels can cause
sensor damage. Do not use tire sealant from a can, or
balance beads if your vehicle is equipped with a
TPM System, as damage to the sensors may result.
312 STARTING AND OPERATING

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:
•The Tire Pressure Monitoring System does not monitor
the temporary spare tire.
•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 underinflated tire causes the
tire to overheat and can lead to tire failure. Underin-
flation 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, even if under-inflation has not
reached the level to trigger illumination of the Tire
Pressure Monitoring Telltale Lamp.
Using Your Compact Spare — Basic Tire
Pressure Monitoring System Only
Your vehicle is equipped with a compact spare wheel and
tire assembly that does not have a tire pressure monitor-
ing sensor. Therefore, it will not be monitored by the Tire
Pressure Monitoring System. In the event that a compact
spare tire is used to replace a low pressure road tire, the
next ignition key cycle will still show the Tire Pressure
