2018 CHRYSLER PACIFICA Low pressure valve

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 “TPMS Warning
Light.” Driving the vehicle may cause the tire pressure to
rise to approximately 28 psi (193 kPa), but the TPMS
Warning Light will still be on. In this situation, the TPMS
Warning Light will turn off only after the tires are inflated
to the vehicle’s recommended cold placard pressure value.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.
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 op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. The TPM sensor is not designed

for use on aftermarket wheels and may contribute to
a poor overall system performance or sensor damage.
Customers are encouraged to use OEM wheels to
assure proper TPM feature operation.
• Using 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 your authorized dealer to have your sensor func-
tion checked.
• After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois-
ture 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.

SAFETY 235

•Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla-
tion 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 underinflation has not reached the level to
trigger illumination of the TPMS Warning Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
Premium 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
• Various tire pressure monitoring system messages,
which display in the instrument cluster
• Tire Pressure Monitoring System Warning Light
Tire Pressure Monitoring Low Pressure Warnings
The TPMS Warning 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 instrument cluster will display an Inflate
to XX message and a graphic showing the pressure values
of each tire with the low tire pressure values in a different
color.
236 SAFETY

CAUTION!
Be sure to mount the inflatable spare tire with the
valve stem facing outward. The vehicle could be dam-
aged if the inflatable spare tire is mounted incorrectly.
NOTE: Do not install the wheel cover on the inflatable
spare tire. 7. Leave the vehicle on the jack and start inflating the
inflatable spare after the tire has been mounted to the
vehicle. Secure the wheel to the hub by tightening the
nuts with wrench. After inflation, once the vehicle is
lowered you will have a second opportunity to “torque”
the lug nuts.
8. Inflate the tire to the prescribed pressure 60 psi (4.2 Bar) using the Portable Air Compressor or Tire Service Kit if
equipped. Refer to “Portable Air Compressor” in this
section for usage procedure if equipped. Refer to “Tire
Service Kit For Inflating Tire” in this section for usage
procedure if equipped.
Inflate the tire to the prescribed pressure 60 psi (4.2 Bar)
using the Portable Air Compressor. Refer to “Portable Air
Compressor” in this section for usage procedure.
9. Lower the vehicle once the inflatable Spare has reached its pressure and the compressor-hose has been removed
from the tire valve.

Using The Power ButtonPush and release the Power Button once
to turn On the Tire Service Kit. Push and
release the Power Button again to turn
Off the Tire Service Kit.
Using The Deflation Button Push the Deflation Button to reduce the
air pressure in the tire if it becomes
over-inflated.
Tire Service Kit Usage Precautions
• Replace the Tire Service Kit Sealant Bottle prior to the
expiration date (printed at the lower right hand corner
on the bottle label) to assure optimum operation of the
system. Refer to “Sealant Bottle Replacement” in this
section. •
The Sealant Bottle is a one tire application use and needs
to be replaced after each use. Always replace these
components immediately at your original equipment
vehicle dealer.
• When the Tire Service Kit sealant is in a liquid form,
clean water, and a damp cloth will remove the material
from the vehicle or tire and wheel components. Once the
sealant dries, it can easily be peeled off and properly
discarded.
• For optimum performance, make sure the valve stem on
the wheel is free of debris before connecting the Tire
Service Kit.
• The Tire Service Kit Sealant is only intended to seal
punctures less than 1/4 inch (6 mm) diameter in the
tread/contact surface of your vehicle’s tires.
• The Tire Service Kit Sealant is not intended to seal
punctures on the tires’ side walls.
• You can use the Tire Service Kit air pump to inflate
bicycle tires. The kit also comes with two needles,
located in the Accessory Storage Compartment (on the
bottom of the air pump) for inflating sport balls, rafts, or
similar inflatable items. However, use only the Air Pump
