FORD 2005 F-150 - Manual (Page 116)

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 safety belt systems at all outboard
seating positions (except the driver position, which does not
have this feature) must be checked by an authorized dealer 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.
Safety belt pretensioner
Your vehicle is equipped with safety belt buckle pretensioners at the
driver and front outboard passenger seating positions.
Do NOT place objects between the seats, as this could interfere
with the functioning of the pretensioner.
The driver and front outboard passenger safety belt pretensioners are
designed to activate only during certain frontal or near-frontal collisions
with sufficient longitudinal deceleration. A safety belt buckle
pretensioner is a device which tightens the webbing of the lap and
shoulder belts during some collisions in such a way that they fit more
snugly against the body.
The driver and front outboard passenger safety belt system (including
retractors, buckles and height adjusters) must be replaced if the vehicle
is involved in a collision that results in the activation of the safety belt
pretensioners. Refer to the Safety belt maintenance section in this
chapter.
