78 Seats and Restraints
the child restraint. A child restraint must
never be installed using only the top tether
and anchor.
The LATCH anchorage system can be used
until the combined weight of the child plus
the child restraint is 29.5 kg (65 lbs). Use the
seat belt alone instead of the LATCH
anchorage system once the combined
weight is more than 29.5 kg (65 lbs).

Belt in the Rear Seat) 0 83 or

Child restraints built after March 2014 will
be labeled with the specific child weight up
to which the LATCH system can be used to
install the restraint.
The following explains how to attach a child
restraint with these attachments in the
vehicle.
Not all vehicle seating positions have lower
anchors. In this case, the seat belt must be
used (with top tether where available) to
secure the child restraint. See Securing Child
Restraints (With the Seat Belt in the Rear
Seat) 0 83 or

Lower Anchors
Lower anchors (1) are metal bars built into
the vehicle. There are two lower anchors for
each LATCH seating position that will
accommodate a child restraint with lower
attachments (2).
Top Tether Anchor
A top tether (3,4) is used to secure the top
of the child restraint to the vehicle. A top
tether anchor is built into the vehicle. The
top tether attachment hook (2) on the child
restraint connects to the top tether anchor
in the vehicle in order to reduce the forward
movement and rotation of the child restraint
during driving or in a crash.
The child restraint may have a single
tether (3) or a dual tether (4). Either will
have a single attachment hook (2) to secure
the top tether to the anchor.
Some child restraints with top tethers are
designed for use with or without the top
tether being attached. Others require the
