Seat Belt Pretensioner
The front seat belt system is equipped with pretensioning
devices 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 restraints.
NOTE:These devices are not a substitute for proper seat
belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.
The pretensioners are triggered by the Occupant 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 seat belt system is equipped with an Energy
Management 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 Retractor (ALR)
The seat belts in the passenger seating positions are
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.

208 SAFETY

WARNING!
•All occupants, including the driver, should not oper-
ate a vehicle or sit in a vehicle’s seat until the head
restraints are placed in their proper positions in
order to minimize the risk of neck injury in the event
of a collision.
• Do not place items over the top of the Active Head
Restraint, such as coats, seat covers or portable DVD
players. These items may interfere with the opera-
tion of the Active Head Restraint in the event of a
collision and could result in serious injury or death.
• Active Head Restraints may be deployed if they are
struck by an object such as a hand, foot or loose
cargo. To avoid accidental deployment of the Active
Head Restraint, ensure that all cargo is secured, as
loose cargo could contact the Active Head Restraint
during sudden stops. Failure to follow this warning
could cause personal injury if the Active Head Re-
straint is deployed.
NOTE: For more information on properly adjusting and
positioning the head restraint, refer to “Head Restraints” in
“Getting To Know Your Vehicle.” Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered during a colli-
sion, the front half of the head restraint will be extended
forward and separated from the rear half of the head
restraint (See Image). Do not drive your vehicle after the
AHRs have deployed. The head restraint must be reset into
the original position to best protect the occupant for all
types of collisions. An authorized FCA US LLC dealer must
reset the AHRs on the driver ’s and front passenger ’s seat
before driving. Personally attempting to reset the AHRs

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 operating;
• Whether or not the driver and passenger safety belts
were buckled/fastened;
• How far (if at all) the driver was depressing the accel-
erator 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 conditions 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 investi-
gation.
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.
226 SAFETY

WARNING!(Continued)
Remove the child restraint before adjusting the ve-
hicle seat position. When the vehicle seat has been
adjusted, reinstall the child restraint.
• When your child restraint is not in use, secure it in
the vehicle with the seat belt or LATCH 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.
Children Too Large For Booster Seats
Children who are large enough to wear the shoulder belt
comfortably, and whose legs are long enough to bend over
the front of the seat when their back is against the seatback,
should use the seat belt in a rear seat. Use this simple 5-step
test to decide whether the child can use the vehicle’s seat
belt alone:
1. Can the child sit all the way back against the back of the
vehicle seat?
2. Do the child’s knees bend comfortably over the front of the vehicle seat – while the child is still sitting all the
way back? 3. Does the shoulder belt cross the child’s shoulder be-
tween their neck and arm?
4. Is the lap part of the belt as low as possible, touching the child’s thighs and not the stomach?
5. Can the child stay seated like this for the whole trip?
If the answer to any of these questions was “no,” then the
child still needs to use a booster seat in this vehicle. If the
child is using the lap/shoulder belt, check seat belt fit
periodically and make sure the seat belt buckle is latched.
A child’s squirming or slouching can move the belt out of
position. If the shoulder belt contacts the face or neck,
move the child closer to the center of the vehicle, or use a
booster seat to position the seat belt on the child correctly.
WARNING!
Never allow a child to put the shoulder belt under an
arm or behind their back. In a crash, the shoulder belt
will not protect a child properly, which may result in
serious injury or death. A child must always wear both
the lap and shoulder portions of the seat belt correctly.
230 SAFETY

LATCH-compatible child restraint systems will be
equipped with a rigid bar or a flexible strap on each side.
Each will have a hook or connector to attach to the lower
anchorage and a way to tighten the connection to the
anchorage. Forward-facing child restraints and some rear-
facing child restraints will also be equipped with a tether
strap. The tether strap will have a hook at the end to attach
to the top tether anchorage and a way to tighten the strap
after it is attached to the anchorage.
Center Seat LATCH — Five Or Seven Second Row
Passenger Seating Only
WARNING!
•Do not install a child restraint in the center position
using the LATCH system. This position is not ap-
proved for installing child seats using the LATCH
attachments. You must use the seat belt and tether
anchor to install a child seat in the center seating
position.
• Never use the same lower anchorage to attach more
than one child restraint. Please refer to “To Install A
LATCH-Compatible Child Restraint” for typical in-
stallation instructions.
Vehicle With A Center Arm Rest Tether — Five Or
Seven Passenger Seating Only
For rear-facing child restraints secured in the center seat
position with the vehicle seat belts, the rear center seat
position has an armrest tether that secures the arm rest in
the upward position.
1. To access the center seat arm rest tether, first lower the
arm rest. The tether is located behind the armrest and
hooked onto the plastic seat backing.
Tether Anchorages
240 SAFETY

1. Loosen the adjusters on the lower straps and on thetether strap of the child seat so that you can more easily
attach the hooks or connectors to the vehicle anchor-
ages.
2. Place the child seat between the lower anchorages for that seating position. For some second row seats, you
may need to recline the seat and / or raise the head
restraint to get a better fit. If the rear seat can be moved
forward and rearward in the vehicle, you may wish to
move it to its rear-most position to make room for the
child seat. You may also move the front seat forward to
allow more room for the child seat.
3. Attach the lower hooks or connectors of the child restraint to the lower anchorages in the selected seating
position.
4. If the child restraint has a tether strap, connect it to the top tether anchorage. See the section “Installing Child
Restraints Using the Top Tether Anchorage” for direc-
tions to attach a tether anchor.
5. Tighten all of the straps as you push the child restraint rearward and downward into the seat. Remove slack in
the straps according to the child restraint manufactur-
er ’s instructions. 6. Test that the child restraint is installed tightly by pulling
back and forth on the child seat at the belt path. It
should not move more than 1 inch (25.4 mm) in any
direction.
How To Stow An Unused Switchable-ALR (ALR)
Seat Belt:
When using the LATCH attaching system to install a child
restraint, stow all ALR seat belts that are not being used by
other occupants 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 LATCH system, buckle the seat
belt behind the child restraint and out of the child’s reach.
If the buckled seat belt interferes 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.
242 SAFETY

WARNING!
•Improper installation of a child restraint to the
LATCH anchorages can lead to failure of the re-
straint. The child could be badly injured or killed.
Follow the child restraint manufacturer ’s directions
exactly when installing an infant or child restraint.
• Child restraint anchorages are designed to withstand
only those loads imposed by correctly-fitted child
restraints. Under no circumstances are they to be
used for adult seat belts, harnesses, or for attaching
other items or equipment to the vehicle.
Installing Child Restraints Using The Vehicle 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 properly secure a
child restraint can lead to failure of the restraint. The
child could be badly injured or killed.

WARNING! (Continued)
•Follow the child restraint manufacturer ’s directions
exactly when installing an infant or child restraint.
The seat belts in the 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 so that it is not
necessary to use a locking clip. The ALR retractor can be
“switched” into a locked mode by pulling all of the
webbing out of the retractor and then letting the webbing
retract back into the retractor. If it is locked, the ALR will
make a clicking noise while the webbing is pulled back into
the retractor.
Refer to the “Automatic Locking Mode” description in
“Switchable Automatic Locking Retractors (ALR)” under
“Occupant Restraint Systems” for additional information
on ALR.
Please see the table below and the following sections for
more information.
