Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a twisted lap/
shoulder belt.
1. Position the latch plate as close as possible to theanchor point.
2. At about 6 to 12 inches (15 to 30 cm) above the latch plate, grasp and twist the seat belt webbing 180
degrees to create a fold that begins immediately above
the latch plate.
3. Slide the latch plate upward over the folded webbing. The folded webbing must enter the slot at the top of
the latch plate. 4. Continue to slide the latch plate up until it clears the
folded webbing and the seat belt is no longer twisted.
Adjustable Upper Shoulder Belt Anchorage
In the driver and front passenger seats, the top of the

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 59

As a guide, if you are shorter than average, you will
prefer the shoulder belt anchorage in a lower position,
and if you are taller than average, you will prefer the
shoulder belt anchorage in a higher position. After you
release the anchorage button, try to move it up or down
to make sure that it is locked in position.NOTE:
The adjustable upper shoulder belt anchorage is
equipped with an Easy Up feature. This feature allows
the shoulder belt anchorage to be adjusted in the upward
position without pushing or squeezing the release but-
ton. To verify the shoulder belt anchorage is latched, pull
downward on the shoulder belt anchorage until it is
locked into position.
Seat Belt Extender
If a seat belt is not long enough to fit properly, even when
the webbing is fully extended and the adjustable upper
shoulder belt anchorage (if equipped) is in its lowest
position, your authorized dealer can provide you with a
Seat Belt Extender. The Seat Belt Extender should be used
only if the existing seat belt is not long enough. When the
Seat Belt Extender is not required for a different occu-
pant, it must be removed.

60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

WARNING!
•ONLY use a Seat Belt Extender if it is physically
required in order to properly fit the original seat
belt system. DO NOT USE the Seat Belt Extender
if, when worn, the distance between the front edge
of the Seat Belt Extender buckle and the center of
the occupant’s body is LESS than 6 inches.
• Using a Seat Belt Extender when not needed can
increase the risk of serious injury or death in a
collision. Only use the Seat Belt Extender when the
lap belt is not long enough and only use in the
recommended seating positions. Remove and store
the Seat Belt Extender when not needed.
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 wearing 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 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 Re-
straint Controller (ORC). Like the air bags, the preten-
sioners are single use items. A deployed pretensioner or
a deployed air bag must be replaced immediately.
Energy Management Feature
This vehicle has a seat belt system with an Energy
Management feature in the front seating positions that
may help further reduce the risk of injury in the event of
a collision. This seat belt system has a retractor assembly
that is designed to release webbing in a controlled
manner.
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
62 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

Restraints” section of this manual. The table below
defines the type of feature for each seating position.
•ALR = Switchable Automatic Locking Retractor
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 occupant’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 auto-
matically 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 a vehicle with a rear seat.

WARNING!
•Never place a rear-facing child restraint in front of
an air bag. A deploying Passenger Advanced 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.
• Only use a rear-facing child restraint in a vehicle
with a rear seat.
How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward until the entire seat belt is extracted.
3. Allow the seat belt to retract. As the seat belt retracts, you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode. How To Disengage The Automatic Locking Mode
Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency)
locking mode.
WARNING!
•
The seat belt assembly must be replaced if the
switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the proce-
dures in the Service Manual.
• Failure to replace the seat belt assembly could
increase the risk of injury in collisions.
• Do not use the Automatic Locking Mode to restrain
occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is

Supplemental Active Head Restraints (AHR)
These head restraints are passive, deployable compo-
nents, and vehicles with this equipment cannot be readily
identified by any markings, only through visual inspec-
tion of the head restraint. The head restraint will be split
in two halves, with the front half being soft foam and
trim, the back half being decorative plastic.
How The Active Head Restraints (AHR) Work
The Occupant Restraint Controller (ORC) determines
whether the severity, or type of rear impact will require the Active Head Restraints (AHR) to deploy. If a rear
impact requires deployment, both the driver and front
passenger seat AHRs will be deployed.
When AHRs deploy during a rear impact, the front half
of the head restraint extends forward to minimize the gap
between the back of the occupant’s head and the AHR.
This system is designed to help prevent or reduce the
extent of injuries to the driver and front passenger in
certain types of rear impacts.
NOTE:
The Active Head Restraints (AHR) may or may
not deploy in the event of a front or side impact.
However if during a front impact, a secondary rear
impact occurs, the AHR may deploy based on the sever-
ity and type of the impact.
2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 65

WARNING!
•All occupants, including the driver, should not
operate 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
operation 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 Ac-
tive Head Restraint ensure that all cargo is secured,

as loose cargo could contact the Active Head Re-
straint during sudden stops. Failure to follow this
warning could cause personal injury if the Active
Head Restraint is deployed.
NOTE: For more information on properly adjusting and
positioning the head restraint, refer to “Adjusting Active
Head Restraints” in “Understanding The Features Of
Your Vehicle.”
Resetting Active Head Restraints (AHR)
If the Active Head Restraints are triggered during a
collision, 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 attempt-
ing to reset the AHRs may result in damage to the AHRs
that could impair their function.
