•Trailer length between 20 ft to 30 ft (6 m to 9 m) — Blind
spot zone will be adjusted to 30 ft (9 m)
.
• Trailer length between 30 ft and 39.5 ft (9 m to 12 m) —
Blind spot zone will be adjusted to MAX distance
.
NOTE: Trailer length is determined within +/- 3 feet
(1 meter) of actual length. Trailers that are the same size as
the category limit, 10/20/30 ft (3/6/9 m), could be subject
to being placed in the category above or below the correct
one.
Trailer Merge Warning
Trailer Merge Warning is the extension of the blind spot
function to cover the length of the trailer, plus a safety
margin, to warn the driver when there is a vehicle in the
adjacent lane. The driver is alerted by the illumination of
the BSM warning light located in the outside mirror on the
side the other vehicle is detected. In addition, an audible
(chime) alert will be heard and radio volume reduced.
Refer to “Modes Of Operation” in this section for further
information. NOTE:
•
The Trailer Merge Alert system DOES NOT alert the
driver about rapidly approaching vehicles that are out-
side the detection zones.
• The Blind Spot Monitoring (BSM) system may experi-
ence drop outs (blinking on and off) of the side mirror
warning indicator lamps when a motorcycle or any
small object remains at the side of the vehicle for
extended periods of time (more than a couple of sec-
onds).
• Crowded areas such as parking lots, neighborhoods, etc.
May lead to an increased amount of false alerts. This is
normal operation.
WARNING!
The Blind Spot Monitoring system is only an aid to
help detect objects in the blind spot zones. The BSM
system is not designed to detect pedestrians, bicyclists,
or animals. Even if your vehicle is equipped with the
BSM system, always check your vehicle’s mirrors,
glance over your shoulder, and use your turn signal
before changing lanes. Failure to do so can result in
serious injury or death.
220 SAFETY

Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle recom-
mended cold placard pressure.
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 de-
crease. 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 mile (1.6 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 “Tires” in “Servicing And Maintenance” for infor-
mation 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 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 turnoff until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warning
(Tire Pressure Monitoring [TPM] Telltale Light) illumi-
nates, you must increase the tire pressure to the recom-
mended cold placard pressure in order for the TPM Telltale
Light to turn off. The system will automatically update and
the TPM Telltale Light will turn off once the system
receives the updated tire pressures. 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.
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
Tire Pressure Monitoring Telltale Light off.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of 30
psi (207 kPa). If the ambient temperature is 68°F (20°C) and
the measured tire pressure is 27 psi (186 kPa), a tempera-
ture drop to 20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (158 kPa). This tire pressure is suffi-
ciently low enough to turn on the TPM Telltale Light.
Driving the vehicle may cause the tire pressure to rise to
approximately 27 psi (186 kPa), but the TPM Telltale Light
will still be on. In this situation, the TPM Telltale Light will
5
SAFETY 225

turn off only after the tires are inflated to the vehicle’s
recommended cold placard pressure value.
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. Aftermarket wheels can cause
sensor damage.
• 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 an authorized dealership to have your sensor
function 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.
• 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 TPM Telltale Light.
• Seasonal temperature changes will affect tire pressure,
and the TPMS will monitor the actual tire pressure in the
tire.
226 SAFETY

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

SAFETY 227

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. In
addition, the instrument cluster will display a graphic
showing the pressure values of each tire with the low tire
pressure values in a different color. An Inflate to XX
message will also be displayed.
Should this occur, you should stop as soon as possible and
inflate the tires with a low pressure condition (those in a different color in the instrument cluster graphic) to the
vehicle’s recommended cold placard pressure inflation
value as shown in the
Inflate to XXmessage. Once the
system receives the updated tire pressures, the system will
automatically update, the graphic display in the instru-
ment cluster will return to it’s original color, and the “Tire
Pressure Monitoring Telltale 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
information.
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
Tire Pressure Monitoring Telltale Light off.
Service TPMS Warning
If a system fault is detected, the “Tire Pressure Monitoring
Telltale 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 switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no

228 SAFETY

longer exists, the “Tire Pressure Monitoring Telltale Light”
will no longer flash, and theSERVICE 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:
• Signal interference due to electronic devices or driving
next to facilities emitting the same radio frequencies as
the TPM sensors.
• Installing aftermarket window tinting that contains ma-
terials that may block radio wave signals.
• Accumulation of snow or ice around the wheels or
wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
A system fault may occur due to an incorrect TPM sensor
location condition. When a system fault occurs due to an
incorrect TPM sensor location, the “Tire Pressure Monitor-
ing Telltale 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
“Tire Pressure Temporarily Unavailable” message in place
of the tire pressure display screen. If the ignition switch is
cycled, this sequence will repeat, providing the system fault still exists. If the system fault no longer exists, the
“Tire Pressure Monitoring Telltale Light” will no longer
flash and the tire pressure display screen will be displayed
showing the tire pressure values the correct locations.
Vehicles With Non Matching Full Size Spare Or Compact
Spare
•
The non matching full size spare or compact spare tire
does not have a TPM sensor. Therefore, the TPMS will
not monitor the pressure in the non matching full size
spare or compact spare tire.
• If you install the non matching full size spare or compact
spare tire in place of a road tire that has a pressure below
the low-pressure warning limit, upon the next ignition
switch cycle, the TPM Telltale Light and a “LOW TIRE”
message will remain ON and a chime will sound. In
addition, the graphic in the instrument cluster will still
display a pressure value in a different color and an
“Inflate to XX” message.
•
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the TPM Telltale Light will flash on
and off for 75 seconds and then remain on solid. 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.

SAFETY 229

•For each subsequent ignition switch cycle, a chime will
sound, the TPM Telltale Light will flash on and off for 75
seconds and then remain on solid, and 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.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the non matching
full size spare or compact spare, the TPMS will update
automatically. In addition, the TPM Telltale 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.
Tire Fill Alert
This feature notifies the user when the placard tire pressure
is attained while inflating or deflating the tire.
The customer may choose to disable or enable the Tire Fill
Alert feature through use of the customer settings in the
radio. NOTE:
•
Only one tire can be filled at a time when using the Tire
Fill Alert system.
• The Tire Fill Alert feature cannot be entered if an existing
TPM system fault is set to “active” or if the system is in
deactivation mode (if equipped).
The system will be activated when there is over 1.5 psi (10
kPa) of change in tire pressure. The ignition must be in the
RUN mode, with the transmission in PARK (P).
NOTE: It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the vehicle is in
Tire Fill Alert mode.
When Tire Fill Alert Mode is entered, the tire pressure
display screen will be displayed in the instrument cluster.
Operation:
• The horn will chirp to let the user know when to stop
filling the tire, when it reaches recommended pressure.
• The horn will chirp three times if the tire is over filled
and will continue to chirp every five seconds if the user
continues to inflate the tire.
230 SAFETY

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.
5
SAFETY 233

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.
