FORD 2010 Flex v.1 - Manual (Page 208)

Your vehicle has LATCH lower anchors for child seat installation at the
seating positions marked with the child seat symbol.
The LATCH anchors are located at
the rear section of the rear seat
between the cushion and seat back,
below the locator symbols on the
seatback. Follow the child seat
manufacturer’s instructions to
properly install a child seat with
LATCH attachments.
Follow the instructions on attaching child safety seats with tether straps.
Refer to Attaching child safety seats with tether straps later in this
chapter.
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.
