FORD 2003 Mustang v.2 - Manual (Page 94)

Your vehicle has LATCH anchors for child seat
installation at the seating positions marked with the
child seat symbol.
The center of
the rear seat is
NOT designed as a
seating position. The
LATCH anchors were
not designed to be
used with a child
seat in the center
position and there is
no tether anchor
available at the
center. Putting a
child seat in the
center would also
block access to the
safety restraint
buckles. Use as a
seating position, with
or without a child
restraint, may
increase the risk of
injury or death.
Never attach two LATCH 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.
