Safety Belt Pretensioner - Mercury 2004 Mountaineer Owner's Manual

After any vehicle collision, the combination lap and shoulder belt
system at all passenger seating positions must be checked by a
qualified technician to verify that the "automatic locking retractor"
feature for child seats is still functioning properly, in addition to other
checks for proper seat belt system 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. 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 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
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
pretensioners.
