Lower Anchorages and Top Tethers
for Children (LATCH System)
Your vehicle has the LATCH system. You'll find
anchors (A) for the second row outboard passenger
positions.
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).
1-42
In order to use the system, you need either a
forward-facing child restraint that has attaching
points (B) at its base and a top tether anchor (C), or a
rear-facing child restraint that has attaching points (B),
as shown here.
