286SAFETY
(Continued)
The first stage inflator is triggered immediately
during an impact that requires air bag deployment.
A low energy output is used in less severe
collisions. A higher energy output is used for more
severe collisions.
This vehicle may be equipped with a driver and/or
front passenger seat belt buckle switch that
detects whether the driver or front passenger seat
belt is buckled. The seat belt buckle switch may
adjust the inflation rate of the Advanced Front Air
Bags.
Front Air Bag Operation
Front Air Bags are designed to provide additional
protection by supplementing the seat belts. Front
air bags are not expected to reduce the risk of
injury in rear, side, or rollover collisions. The front
air bags will not deploy in all frontal collisions,
including some that may produce substantial
vehicle damage — for example, some pole
collisions, truck underrides, and angle offset
collisions.
On the other hand, depending on the type and
location of impact, front air bags may deploy in
crashes with little vehicle front-end damage but
that produce a severe initial deceleration.
Because air bag sensors measure vehicle
deceleration over time, vehicle speed and damage
by themselves are not good indicators of whether
or not an air bag should have deployed. Seat belts are necessary for your protection in all
collisions, and also are needed to help keep you in
position, away from an inflating air bag.
When the Occupant Restraint Controller (ORC)
detects a collision requiring the front air bags, it
signals the inflator units. A large quantity of
non-toxic gas is generated to inflate the front air
bags.
The steering wheel hub trim cover and the upper
passenger side of the instrument panel separate
and fold out of the way as the air bags inflate to
their full size. The front air bags fully inflate in less
time than it takes to blink your eyes. The front air
bags then quickly deflate while helping to restrain
the driver and front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect the knees
of the driver and front passenger, and position the
front occupants for improved interaction with the
front air bags.
WARNING!
No objects should be placed over or near the
air bag on the instrument panel or steering
wheel because any such objects could cause
harm if the vehicle is in a collision severe
enough to cause the air bag to inflate.
Do not put anything on or around the air bag
covers or attempt to open them manually. You
may damage the air bags and you could be
injured because the air bags may no longer be
functional. The protective covers for the air
bag cushions are designed to open only when
the air bags are inflating.
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, air bags won’t
deploy at all. Always wear your seat belts even
though you have air bags.
WARNING!
WARNING!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the knee
impact bolsters such as alarm lights, stereos,
citizen band radios, etc.

SAFETY289
NOTE:Air bag covers may not be obvious in the interior
trim, but they will open during air bag deployment.
Rollover Events (If Equipped With Rollover
Sensing)
Side Air Bags and seat belt pretensioners (if
equipped) are designed to activate in certain
rollover events (if equipped with rollover sensing).
The Occupant Restraint Controller (ORC)
determines whether deployment in a particular
rollover event is appropriate, based on the severity
and type of collision. Vehicle damage by itself is not
a good indicator of whether or not Side Air Bags
and seat belt pretensioners should have deployed.
The Side Air Bags and seat belt pretensioners will
not deploy in all rollover events. The rollover
sensing system determines if a rollover event may
be in progress and whether deployment is
appropriate. In the event the vehicle experiences a
rollover or near rollover event, and deployment is
appropriate, the rollover sensing system will deploy
the Side Air Bags and seat belt pretensioners on
both sides of the vehicle.
The SABICs may help reduce the risk of partial or
complete ejection of vehicle occupants through
side windows in certain rollover or side impact
events.Air Bag System Components
NOTE:The Occupant Restraint Controller (ORC) monitors
the internal circuits and interconnecting wiring
associated with electrical Air Bag System Compo -
nents listed below:
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Seat Belt Buckle Switch
Supplemental Side Air Bags — If Equipped
Front and Side Impact Sensors — If Equipped
Seat Belt Pretensioners — If Equipped
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 colli -
sions. 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 permanent
and normally heal quickly. However, if you
haven’t healed significantly within a few days, or
if you have any blistering, see your doctor imme -
diately.
As the air bags deflate, you may see some
smoke-like particles. The particles are a normal
by-product of the process that generates the
non-toxic gas used for air bag inflation. 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.

SAFETY291
Maintaining Your Air Bag System Event Data Recorder (EDR)

This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record, in
certain crash or near crash-like situations, such as
an air bag deployment or hitting a road obstacle,
data that will assist in understanding how a
vehicle’s systems performed. The EDR is designed
to record data related to vehicle dynamics and
safety systems for a short period of time, typically
30 seconds or less. The EDR in this vehicle is
designed to record such data as:

How various systems in your vehicle were oper -
ating;
Whether or not the driver and passenger safety
belts were buckled/fastened;
How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in which
crashes and injuries occur.
NOTE:
EDR data are recorded by your vehicle only if a
non-trivial crash situation occurs; no data are
recorded by the EDR under normal driving condi -
tions and no personal data (e.g., name, gender, age,
and crash location) are recorded. However, other
parties, such as law enforcement, could combine
the EDR data with the type of personally identifying
data routinely acquired during a crash investigation.
To read data recorded by an EDR, special
equipment is required, and access to the vehicle or
the EDR is needed. In addition to the vehicle
manufacturer, other parties, such as law
enforcement, that have the special equipment,
can read the information if they have access to the
vehicle or the EDR.
CHILD RESTRAINTS
Everyone in your vehicle needs to be buckled up at
all times, including babies and children. Every
state in the United States, and every Canadian
province, requires that small children ride in
proper restraint systems. This is the law, and you
can be prosecuted for ignoring it.
Children 12 years or younger should ride properly
buckled up in a rear seat, if available. According to
crash statistics, children are safer when properly
restrained in the rear seats rather than in the front.
WARNING!

Modifications to any part of the air bag system
could cause it to fail when you need it. You
could be injured if the air bag system is not
there to protect you. Do not modify the compo
-
nents or wiring, including adding any kind of
badges or stickers to the steering wheel hub
trim cover or the upper passenger side of the
instrument panel. Do not modify the front
fascia/bumper, vehicle body structure, or add
aftermarket side steps or running boards.
It is dangerous to try to repair any part of the air
bag system yourself. Be sure to tell anyone who
works on your vehicle that it has an air bag
system.
Do not attempt to modify any part of your air
bag system. The air bag may inflate accidentally
or may not function properly if modifications are
made. Take your vehicle to an authorized dealer
for any air bag system service. If your seat,
including your trim cover and cushion, needs to
be serviced in any way (including removal or
loosening/tightening of seat attachment bolts),
take the vehicle to an authorized dealer. Only
manufacturer approved seat accessories may
be used. If it is necessary to modify the air bag
system for persons with disabilities, contact an
authorized dealer.

WARNING!
In a collision, an unrestrained child can become
a projectile inside the vehicle. The force required
to hold even an infant on your lap could become
so great that you could not hold the child, no
matter how strong you are. The child and others
could be badly injured or killed. Any child riding
in your vehicle should be in a proper restraint for
the child’s size.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nuts/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS The best protection against carbon monoxide entry
into the vehicle body is a properly maintained
engine exhaust system.
Whenever a change is noticed in the sound of the
exhaust system, when exhaust fumes can be
detected inside the vehicle, or when the underside
or rear of the vehicle is damaged, have an
authorized dealer inspect the complete exhaust
system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit
exhaust fumes to seep into the passenger
compartment. In addition, inspect the exhaust
system each time the vehicle is raised for
lubrication or oil change. Replace as required.
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.

314IN CASE OF EMERGENCY
SOS Call System Limitations
Vehicles sold in Mexico DO NOT have SOS Call
system capabilities.
SOS or other emergency line operators in Mexico
may not answer or respond to SOS system calls. If the SOS Call system detects a malfunction, any
of the following may occur at the time the
malfunction is detected, and at the beginning of
each ignition cycle:
The overhead console light located within the
ASSIST and SOS buttons will continuously illumi
-
nate red.
The Device Screen will display the following
message: “Vehicle device requires service.
Please contact an authorized dealer.”
An In-Vehicle Audio message will state “Vehicle
device requires service. Please contact an
authorized dealer.” Even if the SOS Call system is fully functional,
factors beyond FCA US LLC’s control may prevent
or stop the SOS Call system operation. These
include, but are not limited to, the following
factors:
The ignition is in the OFF position.
The vehicle’s electrical systems are not intact.
The SOS Call system software and/or hardware
are damaged during a crash.
The vehicle battery loses power or becomes
disconnected during a vehicle crash.
LTE (voice/data) or 4G (data) network and/or
Global Positioning Satellite signals are unavail
-
able or obstructed.
Equipment malfunction at the SOS operator
facility.
Operator error by the SOS operator.
LTE (voice/data) or 4G (data) network conges -
tion.
Weather.
Buildings, structures, geographic terrain, or
tunnels.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add after -
market electrical equipment to the vehicle’s
electrical system. This may prevent your
vehicle from sending a signal to initiate an
emergency call. To avoid interference that can
cause the SOS Call system to fail, never add
aftermarket equipment (e.g., two-way mobile
radio, CB radio, data recorder, etc.) to your
vehicle’s electrical system or modify the
antennas on your vehicle. IF YOUR VEHICLE
LOSES BATTERY POWER FOR ANY REASON
(INCLUDING DURING OR AFTER AN ACCI -
DENT), THE UCONNECT FEATURES, APPS AND
SERVICES, AMONG OTHERS, WILL NOT
OPERATE.
Modifications to any part of the SOS Call
system could cause the air bag system to fail
when you need it. You could be injured if the
air bag system is not there to help protect you.
WARNING!
WARNING!
Ignoring the overhead console light could
mean you will not have SOS Call services. If
the overhead console light is illuminated, have
an authorized dealer service the SOS Call
system immediately.
The Occupant Restraint Control module turns
on the air bag Warning Light on the instrument
panel if a malfunction in any part of the
system is detected. If the Air Bag Warning
Light is illuminated, have an authorized dealer
service the Occupant Restraint Control system
immediately.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
instrument panel, visible through the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for example,
repeated brake applications with the engine off),
the brakes will still function. However, you will
experience a substantial increase in braking effort
to stop the vehicle. If either the front or rear hydraulic system loses
normal braking capability, the remaining system
will still function with some loss of overall braking
effectiveness. This will be evident by increased
pedal travel during application, greater pedal force
required to slow or stop, and activation of the
Brake Warning Light and/or the ABS Warning Light
during brake use.
HYDRAULIC BRAKE ASSIST —
I
F EQUIPPED
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the power
steering system. You may experience some
clicking or hissing noises from the hydro-boost
system during hard braking conditions.
NOTE:Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
