Ú page 237.OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in
your vehicle are the restraint systems:
OCCUPANT RESTRAINT SYSTEMS
F
EATURES
Seat Belt Systems
Supplemental Restraint Systems (SRS) Air
Bags
Child Restraints
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
IMPORTANT SAFETY PRECAUTIONS
Please pay close attention to the information in
this section. It tells you how to use your restraint
system properly, to keep you and your
passengers as safe as possible.
Here are some simple steps you can take to
minimize the risk of harm from a deploying air
bag:
1. Children 12 years old and under should
always ride buckled up in the rear seat of a
vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat belt properly must be secured
in the appropriate child restraint or
belt-positioning booster seat in a rear
seating position Ú page 355.
3. If a child from 2 to 12 years old (not in a rear-facing child restraint) must ride in the
front passenger seat, move the seat as far
back as possible and use the proper child
restraint Ú page 355.
4. Never allow children to slide the shoulder belt behind them or under their arm.
5. You should read the instructions provided with your child restraint to make sure that
you are using it properly.
6. All occupants should always wear their lap and shoulder belts properly.
7. The driver and front passenger seats should be moved back as far as practical to allow
the front air bags room to inflate.

SAFETY349
for any reason, take the vehicle to an authorized
dealer. Only FCA US LLC approved seat
accessories may be used.
The following requirements must be strictly
followed:
Do not modify the front passenger seat
assembly or components in any way.
Do not use prior or future model year seat
covers or cushions not designated by FCA US
LLC for the specific model being repaired.
Always use the correct seat cover and
cushion specified for the vehicle.
Do not replace the seat cover or cushion with
an aftermarket seat cover or cushion.
Do not add a secondary seat cover or mat.
At no time should any Supplemental
Restraint System (SRS) component or SRS
related component or fastener be modified
or replaced with any part except those which
are approved by FCA US LLC.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.
Supplemental Side Air Bags
Supplemental Seat-Mounted Side Air Bags
(SABs)
This vehicle is equipped with Supplemental
Seat-Mounted Side Air Bags (SABs).
Supplemental Seat-Mounted Side Air Bags
(SABs) are located in the outboard side of the
front seats. The SABs are marked with “SRS
AIRBAG” or “AIRBAG” on a label or on the seat
trim on the outboard side of the seats.
The SABs may help to reduce the risk of
occupant injury during certain side impacts, in
addition to the injury reduction potential
provided by the seat belts and body structure.
WARNING!
Unapproved modifications or service proce -
dures to the passenger seat assembly, its
related components, seat cover or cushion
may inadvertently change the air bag
deployment in case of a frontal collision.
This could result in death or serious injury
to the front passenger if the vehicle is
involved in a collision. A modified vehicle
may not comply with required Federal
Motor Vehicle Safety Standards (FMVSS)
and/or Canadian Motor Vehicle Safety
Standards (CMVSS).
If it is necessary to modify the air bag
system for persons with disabilities,
contact an authorized dealer.
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.

IN CASE OF EMERGENCY
HAZARD WARNING FLASHERS

Hazard Warning Flashers Switch

The Hazard Warning Flashers switch is located
on the upper switch bank just below the radio.
NOTE:
If your vehicle is equipped with a 12–inch
Uconnect display, the Hazard Warning Flashers
switch is located above the display. Push the switch to turn on the Hazard Warning
Flashers. When the switch is activated, all
directional turn signals will flash on and off to
warn oncoming traffic of an emergency. Push
the switch a second time to turn off the Hazard
Warning Flashers.
This is an emergency warning system and it
should not be used when the vehicle is in
motion. Use it when your vehicle is disabled and
it is creating a safety hazard for other motorists.
When leaving the vehicle to seek assistance,
the Hazard Warning Flashers will continue to
operate even though the ignition is placed in the
OFF position.
NOTE:
With extended use the Hazard Warning
Flashers may wear down your battery.

(Continued)
NOTE:
Your vehicle may be transmitting data
Ú page 482 as authorized by the subscriber.
Once a connection is made between the
vehicle’s SOS Call system and the SOS oper -
ator, the SOS operator may be able to open a
voice connection with the vehicle to deter -
mine if additional help is needed. Once the
SOS operator opens a voice connection with
the vehicle’s SOS Call system, the operator
should be able to speak with you or other
vehicle occupants and hear sounds occurring in the vehicle. The vehicle’s SOS Call system
will attempt to remain connected with the
SOS operator until the SOS operator termi
-
nates the connection.
5. The SOS operator may attempt to contact appropriate emergency responders and
provide them with important vehicle
information and GPS coordinates.
WARNING!
ALWAYS obey traffic laws and pay attention to
the road. ALWAYS drive safely with your hands
on the steering wheel. You have full
responsibility and assume all risks related to
the use of the features and applications in
this vehicle. Only use the features and
applications when it is safe to do so. Failure
to do so may result in an accident involving
serious injury or death.
WARNING!
If anyone in the vehicle could be in danger
(e.g., fire or smoke is visible, dangerous
road conditions or location), do not wait for
voice contact from an Emergency Services
Agent. All occupants should exit the vehicle
immediately and move to a safe location.
Never place anything on or near the
vehicle’s operable network and GPS
antennas. You could prevent operable
network and GPS signal reception, which
can prevent your vehicle from placing an
emergency call. An operable network and
GPS signal reception is required for the SOS
Call system to function properly.
The SOS Call system is embedded into the
vehicle’s electrical system. Do not add
aftermarket electrical equipment to the
vehicle’s electrical system. This may
prevent your vehicle from sending a signal
to initiate an emergency call. To avoid inter -
ference 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 ACCIDENT), 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.
