cluster will come on when the ignition isplaced in the ON/RUN or ACC/ON/RUN posi-
tion, and when ESC is activated. It should go
out with the engine running. If the “ESC
Indicator Light” comes on continuously with
the engine running, a malfunction has been
detected in the ESC system. If this warning
light remains on after several ignition cycles,
and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph
(48 km/h), see an authorized dealer as soon
as possible to have the problem diagnosed
and corrected.

Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard
Diagnostic system (OBD II) and a connection
port to allow access to information related to
the performance of your emissions controls.
Authorized service technicians may need to
access this information to assist with the
diagnosis and service of your vehicle and
emissions system.
WARNING!
• ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
• If unauthorized equipment is connected
to the OBD II connection port, such as a
driver-behavior tracking device, it may:
• Be possible that vehicle systems,
including safety related systems,
could be impaired or a loss of ve-
hicle control could occur that may
result in an accident involving seri-
ous injury or death.
WARNING!
• Access, or allow others to access,
information stored in your vehicle
systems, including personal infor-
mation.

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 (Refer to “Child
Restraints” in this section for further in-formation) must be secured in the appro-
priate child restraint or belt-positioning
booster seat in a rear seating position.
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 (Refer to “Child Re-
straints” in this section for further
information).
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.8. Do not lean against the door or window. If
your vehicle has side air bags, and deploy-
ment occurs, the side air bags will inflate
forcefully into the space between occu-
pants and the door and occupants could
be injured.
9. If the air bag system in this vehicle needs
to be modified to accommodate a dis-
abled person, refer to the “Customer As-
sistance” section for customer service
contact information.
WARNING!
• NEVER use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERI-
OUS INJURY to the CHILD can occur.
• Never install a rear-facing child restraint
in the front seat of a vehicle. Only use a
rear-facing child restraint in the rear
seat. If the vehicle does not have a rear
seat, do not transport a rear-facing child
restraint in that vehicle.

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 passen-
ger 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.
Rear Seat BeltAlert
Rear Seat BeltAlert shows the driver whether
the seat belts in the rear seat are buckled or
unbuckled. When the ignition switch is in the
START or ON/RUN position, a Seat Belt Re-
minder Light turns on for each rear seat
position. If a seat belt is buckled, the Seat
Belt Reminder Light for that position will
illuminate solid green. If a seat belt is un-
buckled, the Seat Belt Reminder Light will
illuminate red. If a rear passenger unbuckles
a seat belt that was buckled at the start of the
trip, a single chime will sound and the Seat
Belt Reminder Light for that position willchange from solid green to blinking red. This
will alert the driver to stop the vehicle until
the rear passenger buckles the seat belt
again. After the driver and outboard front seat
passenger have buckled their seat belts all
Seat Belt Reminder Lights will turn off.
BeltAlert can be activated or deactivated by
an authorized dealer. FCA US LLC does not
recommend deactivating BeltAlert.
NOTE:
If BeltAlert has been deactivated, 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.
• It is dangerous to ride in a cargo area,
inside or outside of a vehicle. In a colli-
sion, people riding in these areas are
more likely to be seriously injured or
killed.
• Do not allow people to ride in any area of
your vehicle that is not equipped with
seats and seat belts.
101

WARNING!
• If the mini-latch plate and mini-buckle
are not properly connected when the
seat belt is used by an occupant, the
seat belt will not be able to provide
proper restraint and will increase the risk
of injury in a collision.
• When reattaching the mini-latch plate
and mini-buckle, ensure the seat belt
webbing is not twisted. If the webbing is
twisted, follow the preceding procedure
to detach the mini-latch plate and mini-
buckle, untwist the webbing, and reat-
tach the mini-latch plate and mini-
buckle.
• When the center seat belt is in use,
make sure that any cargo in the cargo
compartment is properly secured and
does not contact the seat belt webbing,
and that there is no slack in the center
shoulder belt webbing.
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants
including pregnant women: the risk of injury
in the event of an accident is reduced for the
mother and the unborn child if they are wear-
ing a seat belt.
Position the lap belt snug and low below the
abdomen and across the strong bones of the
hips. Place the shoulder belt across the chest
and away from the neck. Never place the
shoulder belt behind the back or under the
arm.
Seat Belt Pretensioner
The front and second row outboard seat belt
systems are equipped with pretensioning de-
vices that are designed to remove slack from
the seat belt in the event of a collision. These
devices may improve the performance of the
seat belt by removing slack from the seat belt
early in a collision. Pretensioners work for all
size occupants, including those in child re-
straints.
NOTE:
These devices are not a substitute for proper
seat belt placement by the occupant. The
seat belt still must be worn snugly and posi-
tioned properly.
The pretensioners are triggered by the Occu-
pant Restraint Controller (ORC). Like the air
bags, the pretensioners are single use items.
A deployed pretensioner or a deployed air bag
must be replaced immediately.
Energy Management Feature
The front and second row outboard seat belt
systems are equipped with an Energy Man-
agement feature that may help further reduce

the risk of injury in the event of a collision.
The seat belt system has a retractor assembly
that is designed to release webbing in a
controlled manner.
Switchable Automatic Locking Retractors
(ALR) — If Equipped
The seat belts in the passenger seating posi-
tions may be equipped with a Switchable
Automatic Locking Retractor (ALR) which is
used to secure a child restraint system. For
additional information, refer to “Installing
Child Restraints Using The Vehicle Seat
Belt” under the “Child Restraints” section of
this manual. The figure below illustrates the
locking feature for each seating position.If the passenger seating position is equipped
with an ALR and is being used for normal
usage, only pull the seat belt webbing out far
enough to comfortably wrap around the occu-
pant’s mid-section so as to not activate the
ALR. If the ALR is activated, you will hear a
clicking sound as the seat belt retracts. Allow
the webbing to retract completely in this case
and then carefully pull out only the amount of
webbing necessary to comfortably wrap
around the occupant’s mid-section. Slide the
latch plate into the buckle until you hear a
"click."In Automatic Locking Mode, the shoulder
belt is automatically pre-locked. The seat
belt will still retract to remove any slack in
the shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in
a seating position that has a seat belt with
this feature. Children 12 years old and under
should always be properly restrained in the
rear seat of a vehicle with a rear seat.
WARNING!
• NEVER use a rearward facing child re-
straint on a seat protected by an ACTIVE
AIRBAG in front of it, DEATH or SERI-
OUS INJURY to the CHILD can occur.
• Never install a rear-facing child restraint
in the front seat of a vehicle. Only use a
rear-facing child restraint in the rear
seat. If the vehicle does not have a rear
seat, do not transport a rear-facing child
restraint in that vehicle.
• A deploying passenger front air bag can
cause death or serious injury to a child
12 years or younger, including a child in
a rear-facing child restraint.

Group 2
Children who weigh between 15 kg and 25 kg
and who are too big for the Group 1 child
restraint may use a Group 2 child restraint
system.
As shown in fig. C, the Group 2 child restraint
system positions the child correctly with re-
spect to the seat belt so that the shoulder belt
crosses the child’s chest and not the neck,
and the lap belt is snug on the pelvis and not
the abdomen.
Group 3
Children who weigh between 22 kg and 36 kg
and who are tall enough to use the adult
shoulder belt may use a Group 3 child re-
straint. Group 3 child restraints position the
lap belt on the child’s pelvis. The child must
be tall enough that the shoulder belt crosses
the child’s chest and not their neck.
Fig. D shows an example of a Group 3 child
restraint system correctly positioning the
child on the rear seat.
WARNING!
• Improper installation can lead to failure
of an infant or child restraint. It could
come loose in a collision. The child
could be badly injured or killed. Follow
the child restraint manufacturer’s direc-
tions exactly when installing an infant or
child restraint.
• After a child restraint is installed in the
vehicle, do not move the vehicle seat
forward or rearward because it can
loosen the child restraint attachments.
Remove the child restraint before ad-
justing the vehicle seat position. When
the vehicle seat has been adjusted, re-
install the child restraint.
• When your child restraint is not in use,
secure it in the vehicle with the seat belt
or ISOFIX anchorages, or remove it from
the vehicle. Do not leave it loose in the
vehicle. In a sudden stop or accident, it
could strike the occupants or seatbacks
and cause serious personal injury.

3. Attach the tether strap hook of the child
restraint to the top tether anchorage as
shown in the diagram.
4. Remove slack in the tether strap accord-
ing to the child restraint manufacturer’s
instructions.
WARNING!
• An incorrectly anchored tether strap
could lead to increased head motion and
possible injury to the child. Use only the
anchorage position directly behind the
child seat to secure a child restraint top
tether strap.
• If your vehicle is equipped with a split
rear seat, make sure the tether strap
does not slip into the opening between
the seatbacks as you remove slack in the
strap.
How To Stow An Unused Switchable-ALR
(ALR) Seat Belt:
When using the ISOFIX attaching system to
install a child restraint, stow all ALR seat
belts that are not being used by other occu-
pants or being used to secure child restraints.
An unused belt could injure a child if they
play with it and accidentally lock the seat belt
retractor. Before installing a child restraint
using the ISOFIX system, buckle the seat belt
behind the child restraint and out of the
child’s reach. If the buckled seat belt inter-
feres with the child restraint installation,instead of buckling it behind the child re-
straint, route the seat belt through the child
restraint belt path and then buckle it. Do not
lock the seat belt. Remind all children in the
vehicle that the seat belts are not toys and
that they should not play with them.
Installing Child Restraints Using The Ve-
hicle Seat Belt
Child restraint systems are designed to be
secured in vehicle seats by lap belts or the
lap belt portion of a lap/shoulder belt.
WARNING!
• Improper installation or failure to prop-
erly secure a child restraint can lead to
failure of the restraint. The child could
be badly injured or killed.
• Follow the child restraint manufactur-
er’s directions exactly when installing an
infant or child restraint.
The seat belts in the rear passenger seating
positions are equipped with a Switchable
Automatic Locking Retractor (ALR) that is
designed to keep the lap portion of the seat
belt tight around the child restraint. The ALRTether Anchorage Locations
