2015 CHRYSLER TOWN AND COUNTRY tire pressure

wear and correct cold tire inflation pressures. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed. Refer to the paragraph on
“Tread Wear Indicator.” Refer to the Tire and Loading
Information placard or the Vehicle Certification Label for
the size designation of your tire. The Load Index and
Speed Symbol for your tire will be found on the original
equipment tire sidewall. See the Tire Sizing Chart ex-
ample found in the Tire Safety Information section of this
manual for more information relating to the Load Index
and Speed Symbol of a tire.
It is recommended to replace the two front tires or two
rear tires as a pair. Replacing just one tire can seriously
affect your vehicle’s handling. If you ever replace a
wheel, make sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact your authorized tire
dealer or original equipment dealer with any questions
you may have on tire specifications or capability. Failure
to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
WARNING!
•Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combinations
of unapproved tires and wheels may change sus-
pension dimensions and performance characteris-
tics, resulting in changes to steering, handling, and
braking of your vehicle. This can cause unpredict-
able handling and stress to steering and suspen-
sion components. You could lose control and have
a collision resulting in serious injury or death. Use
only the tire and wheel sizes with load ratings
approved for your vehicle.

538 STARTING AND OPERATING

TIRE PRESSURE MONITOR SYSTEM (TPMS)
The TPMS will warn the driver of a low tire pressure
based on the cold inflation tire placard pressure require-
ments found on the tire placard label located on the
driver’s-side B-Pillar.
The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12°F (6.5°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after a vehicle has not been driven for more than
three hours - and in outside ambient temperature.Refer
to “Tires – General Information” in “Starting and
Operating” 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 warning
threshold for any reason, including low temperature
effects, or natural air 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 recommended
cold tire placard pressure. Once the low tire pressure
warning has been illuminated, the tire pressure must be
increased to the recommended cold tire placard pressure
in order for the “Tire Pressure Monitoring Telltale Light”
to be turned off.
NOTE:When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
542 STARTING AND OPERATING

The system will automatically update and the “Tire
Pressure Monitoring Telltale Light” will extinguish once
the updated tire pressures have been received.
NOTE:The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this infor-
mation.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire placard
pressure of 35 psi (241 kPa). If the ambient temperature is
68°F (20°C) and the measured tire pressure is 30 psi
(207 kPa), a temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 26 psi (179 kPa). This
tire pressure is sufficiently low enough to turn on the
“Tire Pressure Monitoring Telltale Light.” Driving the
vehicle may cause the tire pressure to rise to approxi-
mately 30 psi (207 kPa), but the “Tire Pressure Monitor-
ing Telltale Light” will still be on. In this situation, the
“Tire Pressure Monitoring Telltale Light” will turn off
only after the tires have been inflated to the vehicle’s
recommended cold tire placard pressure value.
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. Us-
ing aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to be-
come inoperable. After using an aftermarket tire
sealant it is recommended that you take your
vehicle to an authorized service center to have your
sensor function checked.

CAUTION!(Continued)
•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 TPMS 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
gage, even if under-inflation has not reached the level
to trigger illumination of the “Tire Pressure Monitor-
ing Telltale Light.”
•Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in
the tire.
Base System
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure lev-
els. Sensors, mounted to each wheel as part of the valve
stem, transmit tire pressure readings to the Receiver
Module.
544 STARTING AND OPERATING

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 Basic TPMS consists of the following components:
•Receiver Module
•Four Tire Pressure Monitoring Sensors
•TPMS Telltale Warning Light
Tire Pressure Monitoring Low Tire Pressure
Warnings
The “Tire Pressure Monitoring Telltale Light”
will illuminate in the instrument cluster, a
“LOW TIRE PRESSURE” message will display
in the instrument cluster, and an audible chime
will be activated when one or more of the four active
road tire pressures are low. 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 tire placard pressure value
(located on the placard label on the driver’s-side B-Pillar).
NOTE:When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
The system will automatically update and the “Tire
Pressure Monitoring Telltale Light” will extinguish once
the updated tire pressures have been received.
NOTE:The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this infor-
mation.
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. If the ignition switch is cycled, this sequence will
5
STARTING AND OPERATING 545

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 with any of the following scenarios:
•Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
•Installing some form of aftermarket window tinting
that affects radio wave signals.
•Accumulation of excessive snow and/or ice around
the wheels or wheel housings.
•Using tire chains on the vehicle.
•Using wheels/tires not equipped with TPMS sensors.
Vehicles With Compact Spare
•The compact spare tire (if equipped) does not have a
TPMS sensor. Therefore the TPMS will not monitor the
pressure in the compact spare tire.
•If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure warn-
ing limit, upon the next ignition switch cycle, a chime
will sound, a “LOW TIRE PRESSURE” message will be
displayed and the “Tire Pressure Monitoring Telltale
Light” will turn on.
•After driving for up to 20 minutes above 15 mph
(24 km/h), the “Tire Pressure Monitoring Telltale
Light” will flash on and off for 75 seconds and then
remain on solid.
546 STARTING AND OPERATING

•For each subsequent ignition switch cycle, a chime will
sound, the “Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds and then remain on
solid.
•Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare
tire, the TPMS will automatically update, and the “Tire
Pressure Monitoring Telltale Light” will turn off as
long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires.
NOTE:The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) for the TPMS to receive
this information.
Premium System — If Equipped
The TPMS uses wireless technology with wheel rim-
mounted electronic sensors to monitor tire pressure lev-
els. Sensors mounted to each wheel as part of the valve
stem transmit tire pressure readings to the Receiver
Module.
NOTE:It is particularly important to regularly check
and maintain proper tire pressure in all the tires.
The Premium TPMS consists of the following compo-
nents:
•Receiver Module
•Four TPMS Sensors
•Various TPMS messages, which display in the Elec-
tronic Vehicle Information Center (EVIC), and graphics
displaying tire pressures
•TPMS Telltale Warning Light

STARTING AND OPERATING 547

TPMS Low Pressure Warnings
The “Tire Pressure Monitoring Telltale Light” 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. In addition, the EVIC will display a
“LOW TIRE” message and a graphic display of the
pressure value(s) with the low tire(s) flashing. An#Inflate
Tire to XX#message will also be displayed.
Should a low tire condition occur on any of the four
active road tire(s), you should stop as soon as possible,
and inflate the low tire(s) that is flashing on the graphic
display to the vehicle’s recommended cold tire pressure
value as shown in the#Inflate Tire to XX#message.
NOTE:When filling warm tires, the tire pressure may
need to be increased up to an additional 4 psi (30 kPa)
above the recommended cold placard pressure in order
to turn the Tire Pressure Monitoring Telltale Light off.
The system will automatically update, the graphic dis-
play of the pressure value(s) will stop flashing, and the
“Tire Pressure Monitoring Telltale Light” will extinguish
once the updated tire pressure(s) have been received.
NOTE:The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) to receive this infor-
mation.
SERVICE TPM SYSTEM Message
The “Tire Pressure Monitoring Telltale Light” will flash
on and off for 75 seconds, and remain on solid when a
system fault is detected. The system fault will also sound
a chime. The EVIC will display a “SERVICE TPM SYS-
TEM” message for a minimum of five seconds. This
message is then followed by a graphic display, with--in
place of the pressure value(s) indicating which TPMS
Sensor(s) is not being received.
