Ford 2009 F-150 Owner's Manual page 207

Your vehicle is equipped with LATCH lower anchors for child seat
installation at the following seating positions (LATCH is not available on
F150 Regular cab) :
• F150 SuperCab and CrewCab
The LATCH anchors are located at
the rear section of the rear seat
between the cushion and seatback.
Follow the child seat manufacturer's
instructions to properly install a
child seat with LATCH attachments.
Follow the instructions later in this chapter on attaching child safety
seats with tether straps.
Attach LATCH lower attachments of the child seat only to the anchors
shown.
WARNING: Never attach two child safety seats to the same
anchor. In a crash, one anchor may not be strong enough to hold
two child safety seat attachments and may break, causing serious
injury or death.
WARNING: Depending on where you secure a child restraint,
and depending on the child restraint design, you may block
access to certain safety belt buckle assemblies and/or LATCH lower
anchors, rendering those features potentially unusable. To avoid risk of
injury, occupants should only use seating positions where they are able
to be properly restrained.
