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.

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
We recommend that pregnant women use the seat belts
throughout their pregnancy. Keeping the mother safe is
the best way to keep the baby safe.
Pregnant women should wear the lap part of the seat belt
across the thighs and as snug across the hips as possible.
Keep the seat belt low so that it does not come across the
abdomen. That way the strong bones of the hips will take
the force if there is a collision.
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) — If Equipped
The seat belts in the passenger seating positions may be
equipped with a Switchable Automatic Locking Retrac-
tors (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 table
below defines the type of feature for each seating posi-
tion.
•ALR = Switchable Automatic Locking Retractor
•Top Tether Anchorage Symbol

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. The Automatic
Locking Mode is available on all passenger-seating posi-
tions with a combination lap/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 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.
(Continued)
WARNING!(Continued)
•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
only used to install rear-facing or forward-facing
child restraints that have a harness for restraining
the child.
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.

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.
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 in a collision,
you must reset the head restraint on the driver ’s and
front passenger ’s seat before driving. You can recognize
when the Active Head Restraint has been triggered by the
fact that they have moved forward (as shown in step
three of the resetting procedure).
1. Grasp the deployed AHR from the rear seat.
2. Position the hands on the top of the deployed AHR at
a comfortable position.

dealer.
