SAFETY157
Entering From The Rear
Vehicles that come up from behind your vehicle
on either side and enter the rear detection zone
with a relative speed of less than 30 mph
(48 km/h).

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly with a relative
speed less than 15 mph (24 km/h) and the
vehicle remains in the blind spot for
approximately 1.5 seconds, the warning light
will be illuminated. If the difference in speed
between the two vehicles is greater than
15 mph (24 km/h), the warning light will not
illuminate.
Overtaking/Approaching
Overtaking/Passing

The BSM system is designed not to issue an
alert on stationary objects such as guardrails,
posts, walls, foliage, berms, snow banks, car
washes etc. However, occasionally the system
may alert on such objects. This is normal
operation and your vehicle does not require
service. The BSM system will not alert you of objects that
are traveling in the opposite direction of the
vehicle in adjacent lanes Ú
page 274.

Opposing Traffic

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.

Rear Cross Path (RCP)
RCP is intended to aid the driver when backing
out of parking spaces where their vision of
oncoming vehicles may be blocked. Proceed
slowly and cautiously out of the parking space
until the rear end of the vehicle is exposed. The
RCP system will then have a clear view of the
cross traffic, and if an oncoming vehicle is
detected, alert the driver.

RCP Detection Zones

RCP monitors the rear detection zones on both
sides of the vehicle, for objects that are moving
toward the side of the vehicle with a minimum
speed of approximately 3 mph (5 km/h), to
objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot
situations. When RCP is on and the vehicle is in REVERSE
(R), the driver is alerted using both the visual
and audible alarms, including reducing the
radio volume.
NOTE:
In a parking lot situation, oncoming vehicles can
be blocked by vehicles parked on either side. If
the sensors are blocked by other structures or
vehicles, the system will not be able to alert the
driver.
Blind Spot Modes
Blind Spot has three selectable modes of
operation that are available in the Uconnect
system.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode, the
BSM system will provide a visual alert in the
appropriate side view mirror based on a
detected object. However, when the system is
operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and
audible alerts when a detected object is
present. Whenever an audible alert is
requested, the radio is muted.
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/
Chime mode, the BSM system will provide a
visual alert in the appropriate side view mirror
based on a detected object. If the turn signal is
then activated, and it corresponds to an alert
present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn
signal and detected object are present on the
same side at the same time, both the visual and
audible alerts will be issued. In addition to the
audible alert the radio (if on) will also be muted.
WARNING!
Rear Cross Path Detection (RCP) is not a
backup aid system. It is intended to be used
to help a driver detect an oncoming vehicle in
a parking lot situation. Drivers must be
careful when backing up, even when using
RCP. Always check carefully behind your
vehicle, look behind you, and be sure to
check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. Failure to do so can result in
serious injury or death.

162SAFETY
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 turn off until the tire pressure is at
or above the recommended cold placard
pressure. Once the low tire pressure warning
(TPMS Warning Light) illuminates, you must
increase the tire pressure to the recommended
cold placard pressure in order for the TPMS
Warning Light to turn off. The system will
automatically update and the TPMS Warning
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 TPMS Warning
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 temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately
23 psi (158 kPa). This tire pressure is
sufficiently low enough to turn on the TPMS
Warning Light. Driving the vehicle may cause
the tire pressure to rise to approximately 27 psi
(186 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.CAUTION!
The TPMS has been optimized for the orig
-
inal equipment tires and wheels. TPMS
pressures and warning have been estab -
lished 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. Aftermarket
wheels can cause sensor damage.
Using aftermarket tire sealants may cause
the Tire Pressure Monitoring System
(TPMS) sensor to become 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 pres -
sure always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.

SAFETY163
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 pres -
sure gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat 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.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsi -
bility 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 Ú page 274.
Base System
This is the TPMS warning indicator
located in the instrument cluster.
The 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
regularly and to maintain the proper pressure.
The TPMS consists of the following
components:
Receiver Module
Four Tire Pressure Monitoring System
sensors
Tire Pressure Monitoring System Warning
Light
Tire Pressure Monitoring Low Pressure
Warnings
The Tire Pressure Monitoring System Warning
Light will illuminate in the instrument cluster, an
audible chime will be activated, and the “Check
tire pressure” message will display 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 placard
pressure value. The system will automatically
update and the Tire Pressure Monitoring
System warning Light will extinguish once the
updated tire pressures have been received.
The vehicle may need to be driven for up to
20 minutes above 15 mph (24 km/h) to receive
this information.

Check TPMS Warnings
The Tire Pressure Monitoring System Warning
Light will flash on and off for 75 seconds and
remain on solid when a system fault is detected,
an audible chime will be activated and the “Tire
Pressure Monitoring Unavailable” message will
display. If the ignition key is cycled, this
sequence will repeat providing the system fault
still exists. The TPMS Warning 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
Snow or ice around the wheels or wheel
housings
Using tire chains on the vehicle
Using wheels/tires not equipped with TPMS
sensors NOTE:
Your vehicle is equipped with a regular size
spare wheel.

1. The spare tire does not have a TPMS
sensor. Therefore, the TPMS will not
monitor the pressure in the spare tire.

2. If a spare tire not equipped with the Tire Pressure Monitoring system sensor is used,
the TPMS Warning Light will turn on,
flashing for 75 seconds and then remaining
solid for each subsequent ignition key cycle.
3. Once you repair or replace the original road tire and reinstall it on the vehicle in place of
the spare tire, the TPMS will update
automatically and the Tire Pressure
Monitoring System Warning Light will
extinguish once the updated tire pressures
have been received. The vehicle may need
to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this
information.
NOTE:
For correct Tire Pressure Monitoring System
behavior, please wait for about 20 minutes in
key-off during each tire substitution.

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 BeltAlert
feature is active whenever the ignition switch is in
the AVV/START or MAR/RUN position.

Initial Indication
If the driver is unbuckled when the ignition
switch is first in the AVV/START or MAR/RUN
position, a chime will signal for a few seconds. If
the driver or outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch
is first in the AVV/START or MAR/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 unbuckled (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.
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
buckled 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.

Air Bag Warning Light
The Occupant Restraint Controller
(ORC) monitors the readiness of the
electronic parts of the air bag system
whenever the ignition switch is in the
AVV/START or MAR/ACC/ON/RUN position. If
the ignition switch is in the STOP/OFF/LOCK
position the air bag system is not on and the air
bags will not inflate. The ORC contains a backup power supply
system that may deploy the air bag system even
if the battery loses power or it becomes
disconnected prior to deployment.

The ORC turns on the Air Bag Warning Light in the
instrument panel for approximately four to eight
seconds for a self-check when the ignition switch
is in the MAR/ACC/ON/RUN position. After the
self-check, the Air Bag Warning Light will turn off.
If the ORC detects a malfunction in any part of the
system, it turns on the Air Bag Warning Light,
either momentarily or continuously. A single
chime will sound to alert you if the light comes on
again after initial startup.

The ORC also includes diagnostics that will
illuminate the instrument panel Air Bag Warning
Light if a malfunction is detected that could
affect the air bag system. The diagnostics also
record the nature of the malfunction. While the
air bag system is designed to be maintenance
free, if any of the following occurs, have an
authorized dealer service the air bag system
immediately.
The Air Bag Warning Light does not come on
during the four to eight seconds when the
ignition switch is first in the MAR/ACC/ON/
RUN position.
The Air Bag Warning Light remains on after
the four to eight-second interval.
The Air Bag Warning Light comes on intermit
-
tently or remains on while driving.
NOTE:
If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant
Restraint Controller (ORC) may also be
disabled. In this condition the air bags may not
be ready to inflate for your protection. Have an
authorized dealer service the air bag system
immediately.
WARNING!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t have
the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if it
comes on as you drive, have an authorized
dealer service the air bag system
immediately.

NOTE:
The Occupant Restraint Controller (ORC) moni -
tors the internal circuits and interconnecting
wiring associated with electrical Air Bag System
Components listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
NOTE:
Front and/or side air bags will not deploy in all
collisions. This does not mean something is
wrong with the air bag system.
If you do have a collision which deploys the air
bags, any or all of the following may occur:
The air bag material may sometimes cause
abrasions and/or skin reddening to the occu -
pants as the air bags deploy and unfold. The
abrasions are similar to friction rope burns or
those you might get sliding along a carpet or
gymnasium floor. They are not caused by
contact with chemicals. They are not perma -
nent and normally heal quickly. However, if
you haven’t healed significantly within a few
days, or if you have any blistering, see your
doctor immediately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a
normal by-product of the process that gener -
ates the non-toxic gas used for air bag infla -
tion. These airborne particles may irritate the
skin, eyes, nose, or throat. If you have skin or eye irritation, rinse the area with cool water.
For nose or throat irritation, move to fresh air.
If the irritation continues, see your doctor. If
these particles settle on your clothing, follow
the garment manufacturer’s instructions for
cleaning.
Do not drive your vehicle after the air bags have
deployed. If you are involved in another
collision, the air bags will not be in place to
protect you.
NOTE:Air bag covers may not be obvious in the inte -
rior trim, but they will open during air bag
deployment.
After any collision, the vehicle should be
taken to an authorized dealer immediately.
WARNING!
Deployed air bags and seat belt
pretensioners cannot protect you in another
collision. Have the air bags, seat belt
pretensioners, and the seat belt retractor
assemblies replaced by an authorized dealer
immediately. Also, have the Occupant
Restraint Controller System serviced as well.
