Safety Belt Pretensioner - Ford Lincoln Navigator Owner's Manual

WARNING: After any vehicle collision, the combination lap and
shoulder belt system at all passenger seating positions must be
checked by an authorized dealer to verify that the "automatic locking
retractor" feature for child seats is still functioning properly, in addition
to other checks for proper safety belt system function.
WARNING: BELT AND RETRACTOR ASSEMBLY MUST BE
REPLACED if the safety belt assembly "automatic locking
retractor" feature or any other safety belt function is not operating
properly. In addition, all safety 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 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.
WARNING: The driver and the right front passenger safety 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 airbags or Safety Canopy and safety belt
pretensioners.
