Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle has the LATCH system. You will find
anchors (A) in the center and right side passenger
second row seating positions for bench seats, and the
outboard passenger positions for bucket seats.
1-60
This system, designed to make installation of child
restraints easier, does not use the vehicle's safety belts.
Instead, it uses vehicle anchors (A, B) and child
restraint attachments to secure the restraints. Some
restraints also use another vehicle anchor to secure a
top tether strap (C).
