FORD 2011 F-150 v.1 - Manual (Page 182)

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
௡ System and safety belt
pretensioners.
WARNING: Failure to replace the safety belt assembly under
the above conditions could result in severe personal injuries in
the event of a collision.
Refer to the Safety belt maintenance section in this chapter.
Safety belt usage sensors
The driver and front outboard passenger safety belt buckles are
equipped with sensors that detect if the safety belts are fastened. The
sensors provide information to the Personal Safety System
௡ which can
then adapt the airbag deployment or safety belt pretensioner activation
based upon safety belt usage.
WARNING: The Personal Safety System
௡ provides the most
benefit to belted occupants. The system monitors and tailors the
airbag deployment based upon safety belt usage. Failure to properly
wear your safety belt will increase your risk of injury.
