•This safety belt system has a retractor assembly that is designed to
extend the seat belt webbing in a controlled manner. This helps
reduce the belt force acting on the user’s chest.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the safety belt assembly automatic locking retractor feature or
any other safety belt function is not operating properly when checked
according to the procedures in Workshop Manual. Failure to replace
the Belt and Retractor assembly could increase the risk of injury in
collisions.
Combination lap and shoulder belts
1. Insert the belt tongue into the proper buckle (the buckle closest to
the direction the tongue is coming from) until you hear a snap and feel it
latch. Make sure the tongue is securely fastened in the buckle.
•Front and rear seats
2. To unfasten, push the release button and remove the tongue from the
buckle.
•Front and rear seats
All safety restraints in the vehicle are combination lap and shoulder
belts. All of the passenger combination lap and shoulder belts have two
types of locking modes described below:

When installing a child safety seat:
•Review and follow the information
presented in theAir bag
supplemental restraint system
(SRS) section in this chapter.
•Use the correct safety belt buckle
for that seating position (the
buckle closest to the direction the
tongue is coming from).
•Insert the belt tongue into the
proper buckle until you hear a
snap and feel it latch. Make sure the tongue is securely fastened in the
buckle.
•Keep the buckle release button pointing up and away from the safety
seat, with the tongue between the child seat and the release button,
to prevent accidental unbuckling.
•Place seat back in upright position.
•Put the safety belt in the automatic locking mode. Refer toAutomatic
locking mode(passenger side front and outboard rear seating
positions) (if equipped) section in this chapter.
Ford recommends the use of a child safety seat having a top tether
strap. Install the child safety seat in a seating position with a tether
anchor. For more information on top tether straps, refer toAttaching
child safety seats with tether straps.in this chapter.
Carefully follow all of the manufacturer’s instructions included
with the safety seat you put in your vehicle. If you do not install
and use the safety seat properly, the child may be injured in a sudden
stop or collision.
Rear-facing child seats or infant carriers should never be placed
in the front seats.

3. While holding the shoulder and
lap belt portions together, route the
tongue through the child seat
according to the child seat
manufacturer’s instructions. Be sure
the belt webbing is not twisted.
4. Insert the belt tongue into the
proper buckle (the buckle closest to
the direction the tongue is coming
from) for that seating position until
you hear a snap and feel the latch
engage. Make sure the tongue is
latched securely by pulling on it.
5. To put the retractor in the
automatic locking mode, grasp the
shoulder portion of the belt and pull
downward until all of the belt is
pulled out and a click is heard.
6. Allow the belt to retract. The belt will click as it retracts to indicate it
is in the automatic locking mode.

7. Pull the lap belt portion across
the child seat toward the buckle and
pull up on the shoulder belt while
pushing down with your knee on the
child seat.
8. Allow the safety belt to retract to
remove any slack in the belt.
9. Before placing the child in the
seat, forcibly move the seat forward
and back to make sure the seat is
securely held in place. To check
this, grab the seat at the belt path
and attempt to move it side to side
and forward. There should be no
more than one inch of movement for
proper installation.
10. Try to pull the belt out of the retractor to make sure the retractor is
in the automatic locking mode (you should not be able to pull more belt
out). If the retractor is not locked, unbuckle the belt and repeat steps
two through nine.
Check to make sure the child seat is properly secured before each use.
Attaching child safety seats with tether straps
Most new forward-facing child safety seats include a tether strap which
goes over the back of the seat and hooks to an anchoring point. Tether
straps are available as an accessory for many older safety seats. Contact
the manufacturer of your child seat for information about ordering a
tether strap.
The rear seats of your vehicle are equipped with built-in tether strap
anchors located behind the seats as shown below.
Seating and Safety Restraints

4. Clip the tether strap to the
anchor.
If the tether strap is clipped incorrectly, the child safety seat
may not be retained properly in the event of a collision.
5. Refer to theInstalling child safety seats in combination lap and
shoulder belt seating positionssection of this chapter for further
instructions to secure the child safety seat.
6. Tighten the child safety seat tether strap according to the
manufacturer’s instructions.
If the safety seat is not anchored properly, the risk of a child
being injured in a collision greatly increases.
Attaching safety seats with LATCH (Lower Anchors and Tethers for
Children) attachments for child seat anchors
Some child safety seats have two rigid or webbing mounted attachments
that connect to two anchors at certain seating positions in your vehicle.
This type of child seat eliminates the need to use seat belts to attach the
child seat. For forward-facing child seats, the tether strap must also be
attached to the proper tether anchor. SeeAttaching safety seats with
tether strapsin this chapter.
