FORD 2003 Explorer Sport Trac v.3 - Manual (Page 81)

Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
right front passenger seating positions.
The safety belt pretensioner removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and Safety Canopy
௢
system. When the safety belt pretensioner deploys, the lap and shoulder
belt are tightened.
When the Safety Canopy
௢ system and/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 or Safety Canopy
௢ and safety belt
pretensioners.
Refer to the Safety belt maintenance section in this chapter.
