4. Position the lap belt across your thighs, below your
abdomen. To remove slack in the lap portion, pull up a
bit on the shoulder belt. To loosen the lap belt if it is too
tight, tilt the latch plate and pull on the lap belt. A snug
belt reduces the risk of sliding under the belt in an
accident.
WARNING!
•A lap belt worn too high can increase the risk of
injury in an accident. The belt forces won’t be at
the strong hip and pelvic bones, but across your
abdomen. Always wear the lap part of your seat
belt as low as possible and keep it snug.
•A twisted belt will not protect you properly. In a
collision, it could even cut into you. Be sure the
belt is straight. If you can’t straighten a belt in
your vehicle, take it to your authorized dealer
immediately and have it fixed.5. Position the shoulder belt on your chest so that it is
comfortable and not resting on your neck. The retractor
will withdraw any slack in the belt.

6. To release the belt, push the red button on the buckle.
The belt will automatically retract to its stowed position.
If necessary, slide the latch plate down the webbing to
allow it to retract fully.
WARNING!
A frayed or torn belt could rip apart in an accident
and leave you with no protection. Inspect the belt
system periodically, checking for cuts, frays, or loose
parts. Damaged parts must be replaced immediately.
Do not disassemble or modify the system. Seat belt
assemblies must be replaced after an accident if they
have been damaged (bent retractor, torn webbing,
etc.).
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 the
anchor point.
2. At about 6 to 12 in (15 to 30 cm) above the latch plate,
grasp and twist the 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.

Adjustable Upper Shoulder Belt Anchorage
In the front seating positions, the shoulder belt can be
adjusted upward or downward to position the belt away
from your neck. Press the release button to release the
anchorage, and then move it up or down to the position
that fits you best.As a guide, if you are shorter than average, you will
prefer a lower position, and if you are taller than average,
you will prefer a higher position. When you release the
button, verify the shoulder belt anchorage is latched by
pulling downward on the shoulder belt anchorage until it
is locked into 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 the release button. To verify the
shoulder belt anchorage is latched, pull downward on
the shoulder belt anchorage until it is locked into
position.
Seat Belts In Passenger Seating Positions
The seat belts in the passenger seating positions are
equipped with Automatic Locking Retractors (ALR)
which are used to secure a child restraint system. For

additional information, refer to “Installing Child Re-
straints Using The Vehicle Seat Belt” under the “Child
Restraints” section. The chart below defines the type of
feature for each seating position.
Driver Center Passenger
First Row N/A N/A ALR
Second Row ALR ALR ALR
Third Row N/A N/A N/A
•N/A — Not Applicable
•ALR — Automatic Locking Retractor
If the passenger seating position is equipped with an
ALR and is being used for normal usage:
Only pull the 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 aratcheting sound as the belt retracts. Allow the webbing
to retract completely in this case and then carefully pull
out only the amount of webbing necessary to comfort-
ably wrap around the occupant’s mid-section. Slide the
latch plate into the buckle until you hear aclick.
Automatic Locking Retractor Mode (ALR) — If
Equipped
In this mode, the shoulder belt is automatically pre-
locked. The belt will still retract to remove any slack in
the shoulder belt. The Automatic Locking Mode is avail-
able on all passenger-seating positions with a combina-
tion lap/shoulder belt. Use the Automatic Locking Mode
anytime a child safety seat is installed in a seating
position that has a belt with this feature. Children
12 years old and under should always be properly
restrained in the rear seat.
58 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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 belt is extracted.
3. Allow the belt to retract. As the belt retracts, you will
hear a clicking sound. This indicates the safety 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 belt and retractor assembly must be replaced
if the seat belt assembly Automatic Locking Re-
tractor (ALR) feature or any other seat belt func-
tion is not working properly when checked ac-
cording to the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in collisions.
Energy Management Feature
This vehicle has a safety belt system with an Energy
Management feature in the front seating positions to help
further reduce the risk of injury in the event of a head-on
accident.
This safety belt system has a retractor assembly that is
designed to release webbing in a controlled manner. This
feature is designed to help reduce the belt force acting on
the occupant’s chest.

WARNING!
•The belt and retractor assembly must be replaced
if the seat belt assembly Automatic Locking Re-
tractor (ALR) feature or any other seat belt func-
tion is not working properly when checked ac-
cording to the procedures in the Service Manual.
•Failure to replace the belt and retractor assembly
could increase the risk of injury in accidents.
Seat Belt Pretensioners
The seat belts for both front seating positions are
equipped with pretensioning devices that are designed to
remove slack from the seat belt in the event of an
accident. These devices may improve the performance of
the seat belt by assuring that the belt is tight about the
occupant early in an accident. 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.
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.
60 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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.

CAUTION!
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 an
accident.
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 an accident,
you must reset the head restraint on the driver ’s and
front passenger seat. 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.
3. Pulldownthenrearwardtowards the rear of the
