FORD 2003 Explorer v.4 - Manual (Page 112)

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. In addition, all
seat belts should be checked for proper function. 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 pretensioners at the driver and
right front passenger seating positions.
The safety belt pretensioner is a device which removes excess webbing
from the safety belt system. The safety belt pretensioner uses the same
crash sensor system as the front air bag and Safety Canopy
௢
supplemental restraint systems. When the safety belt pretensioner
deploys, webbing from the lap and shoulder belt is tightened.
When the Safety Canopy
௢ system or the front airbags are activated, the
safety belt pretensioners for the driver and right front passenger seating
positions will be activated when the respective seatbelt is properly
buckled.
The driver and the right front passenger seat belt system
(including retractors, buckles and height adjusters) must be
replaced if the vehicle is involved in a collision that results in
deployment of front air bags and/or Safety Canopy
௢ and safety belt
pretensioners.
Refer to the Safety belt maintenance section in this chapter.
