When to use the automatic locking mode
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 not available on the driver safety belt.
This mode should be usedany timea child safety seat is installed in a
passenger front or outboard rear seating position (if equipped). Children
12 years old and under should be properly restrained in the rear seat
whenever possible. Refer toSafety restraints for childrenorSafety
seats for childrenlater in this chapter.
How to use the automatic locking mode
•Buckle the combination lap and
shoulder belt.
•Grasp the shoulder portion and
pull downward until the entire
belt is pulled out.
•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
Disconnect 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.
After any vehicle collision, the front passenger and rear outboard
seat belt systems must be checked by a qualified technician to
verify that the“automatic locking retractor”feature for child seats is
still functioning properly. In addition, all seat belts should be checked
for proper function.
BELT AND RETRACTOR ASSEMBLY MUST BE REPLACED if
the seat belt assembly“automatic locking retractor”feature or
any other seat 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.
Energy Management Feature
•This vehicle has a seat belt system with an energy management
feature at the front outboard seating positions to help further reduce
the risk of injury in the event of a head-on collision.
•The front outboard seat belt systems have a retractor assembly that is
designed to pay out webbing in a controlled manner. This feature is
designed to help reduce the belt force acting on the occupant’s chest.
Safety belt replacement label
The short plastic boot on the front
safety belt at the passenger
outboard anchor location covers a
“Replace Belt”label on the safety
belt.

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, unless the passenger airbag On/Off switch is
turned off. SeePassenger airbag on/off switchin this chapter.
