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
(Continued)
CAUTION! (Continued)
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

Should this occur, you should stop as soon as possible and
inflate the tires with low pressure (those in a different color
in the instrument cluster graphic) to the vehicle’s recom-
mended cold placard pressure value as shown in the
Inflate to XXmessage. Once the system receives the
updated tire pressures, the system will automatically up-
date, the pressure values in the graphic display in the
instrument cluster will return to their original color, and
the TPMS Warning Light will turn off. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this informa-
tion.
Service TPMS Warning
When a system fault is detected, the Tire Pressure Monitoring
System (TPMS) Warning Light will flash on and off for 75
seconds and then remain on solid. The system fault will also
sound a chime. In addition, the instrument cluster will
display a SERVICE TPM SYSTEM message for a minimum
of five seconds and then display dashes (- -) in place of the
pressure value to indicate which sensor is not being received.
If the ignition is cycled, this sequence will repeat, providing
the system fault still exists. If the system fault no longer
exists, the TPMS Warning Light will no longer flash, and the
“SERVICE TPM SYSTEM” message will no longer display,
and a pressure value will display in place of the dashes. A
system fault can occur due to any of the following:
•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.
•Lots of snow or ice around the wheels or wheel housings.
•Using tire chains on the vehicle.
•Using wheels/tires not equipped with TPMS sensors.

SAFETY 237

Vehicles With Compact Spare — If Equipped
1. The compact spare tire does not have a tire pressuremonitoring sensor. Therefore, the TPMS will not moni-
tor the pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure warning
limit, upon the next ignition cycle, the TPMS Warning
Light will remain on and a chime will sound. In
addition, the graphic in the instrument cluster will still
display a different color pressure value.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPMS Warning Light will flash
on and off for 75 seconds and then remain on solid. In
addition, the instrument cluster will display a “SER-
VICE TPM SYSTEM” message for five seconds and then
display dashes (- -) in place of the pressure value.
4. For each subsequent ignition cycle, a chime will sound, the TPMS Warning Light will flash on and off for 75
seconds and then remain on solid, and the instrument
cluster will display a “SERVICE TPM SYSTEM” mes-
sage for five seconds and then display dashes (- -) in
place of the pressure value. 5. Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact spare,
the TPMS will update automatically. In addition, the
TPMS Warning Light will turn off and the graphic in the
instrument cluster will display a new pressure value
instead of dashes (- -), as long as no tire pressure is
below the low-pressure warning limit in any of the four
active road tires. The vehicle may need to be driven for
up to 20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can be deac-
tivated if replacing all four wheel and tire assemblies (road
tires) with wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter wheel and
tire assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring (TPM) Sensors. Then, drive the
vehicle for 20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on. The instrument cluster
will display the “SERVICE TPM SYSTEM” message and
then display dashes (- -) in place of the pressure values.
238 SAFETY

Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (- -) will
remain in place of the pressure values.
To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
sensors. Then, drive the vehicle for up to 20 minutes above
15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the
SERVICE TPM SYSTEMmessage will no longer be dis-
played as long as no system fault exists.

SAFETY 239

Seat Belt Systems
Buckle up even though you are an excellent driver, even on
short trips. Someone on the road may be a poor driver and
could cause a collision that includes you. This can happen
far away from home or on your own street.
Research has shown that seat belts save lives, and they can
reduce the seriousness of injuries in a collision. Some of the
worst injuries happen when people are thrown from the
vehicle. Seat belts reduce the possibility of ejection and the
risk of injury caused by striking the inside of the vehicle.
Everyone in a motor vehicle should be belted at all times.
Enhanced Seat Belt Use Reminder System (BeltAlert)
Driver and Passenger BeltAlert (if equipped)
BeltAlert is a feature intended to remind the driver
and outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) to buckle their
seat belts. The Belt Alert feature is active whenever the
ignition switch is in the START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition switch is first
in the START or ON/RUN position, a chime will signal for a few seconds. If the driver or outboard front seat passen-
ger (if equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch is first in
the START or ON/RUN position the Seat Belt Reminder
Light will turn on and remain on until both outboard front
seat belts are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front passenger
seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when the
vehicle is moving above a specified vehicle speed range
and the driver or outboard front seat passenger is unbuck-
led (if equipped with outboard front passenger seat
BeltAlert) (the outboard front passenger seat BeltAlert is
not active when the outboard front passenger seat is
unoccupied). The BeltAlert warning sequence starts by
blinking the Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning sequence
has completed, the Seat Belt Reminder Light will remain on
until the seat belts are buckled. The BeltAlert warning
sequence may repeat based on vehicle speed until the
driver and occupied outboard front seat passenger seat
belts are buckled. The driver should instruct all occupants
to buckle their seat belts.

SAFETY 241

Change of Status
If the driver or outboard front seat passenger (if equipped
with outboard front passenger seat BeltAlert) unbuckles
their seat belt while the vehicle is traveling, the BeltAlert
warning sequence will begin until the seat belts are buck-
led again.
The outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.
BeltAlert may be triggered when an animal or other items
are placed on the outboard front passenger seat or when
the seat is folded flat (if equipped). It is recommended that
pets be restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat belts, and
cargo is properly stowed.
BeltAlert can be activated or deactivated by an authorized
dealer. FCA US LLC does not recommend deactivating
BeltAlert.
NOTE:If BeltAlert has been deactivated and the driver or
outboard front seat passenger (if equipped with outboard
front passenger seat BeltAlert) is unbuckled the Seat Belt
Reminder Light will turn on and remain on until the driver
and outboard front seat passenger seat belts are buckled.Lap/Shoulder Belts
All seating positions in your vehicle are equipped with
lap/shoulder belts.
The seat belt webbing retractor will lock only during very
sudden stops or collisions. This feature allows the shoulder
part of the seat belt to move freely with you under normal
conditions. However, in a collision the seat belt will lock
and reduce your risk of striking the inside of the vehicle or
being thrown out of the vehicle.
WARNING!
• Relying on the air bags alone could lead to more
severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, the air bags won’t deploy at all. Always
wear your seat belt even though you have air bags.
• In a collision, you and your passengers can suffer
much greater injuries if you are not properly buckled
up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.
