Ford 1996 Aerostar Manual page 18

All Two Passenger Bench or Bedseat
In addition to anchorages in the floor and roof
structures, some rear safety belts have a
detachable anchor mounted to the outboard side
of the rear seats. This should remain attached,
except when removing the rear seats.
The second row passenger side outboard seating
position uses a hook above the sliding/cargo
door to stow the shoulder safety belt when
entering or exiting the vehicle or when it is not
being used.
NOTE: When the belt is stowed using the
hook, DO NOT use the hanging belt as
an assist when entering the vehicle.
