Attaching safety seats with LATCH (Lower Anchors and Tethers for
Children) attachments for child seat anchors
Some child safety seats have two rigid or webbing mounted attachments
that connect to two anchors at certain seating positions in your vehicle.
This type of child seat eliminates the need to use seat belts to attach the
child seat. For forward-facing child seats, the tether strap must also be
attached to the proper tether anchor. See Attaching safety seats with
tether straps in this chapter.
Your vehicle has LATCH anchors for child seat installation at the
following locations:
The center of the rear seat is NOT
designed as a seating position. The
LATCH anchors on both sides of the
center of the rear seats are provided
only for child seats installed at the
outboard seats. These anchors are
much closer together than the pairs
of lower anchors for child seat
installation at other seats. DO NOT
install a child seat with LATCH attachments (rigid or mounted on belt
webbing) to the lower anchors on both sides of the center of the rear
seat. Putting a child seat in the center would block access to the seat
belt buckles.
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.
