3. The back of the child restraint should be
secured against the vehicle seatback.
If necessary, adjust or remove the head
restraint/headrest to obtain the correct child
restraint fit. If the head restraint/headrest is
removed, store it in a secure place. Be sure
to reinstall the head restraint/headrest
when the child restraint is removed.
See “Head restraints/headrests” in this sec-
tion for head restraint/headrest adjustment
information.
If the seating position does not have an
adjustable head restraint/headrest and it is
interfering with the proper child restraint fit,
try another seating position or a different
child restraint.
4. For child restraints that are equipped with
webbing-mounted attachments, remove any
additional slack from the anchor attach-
ments. Press downward and rearward firmly
in the center of the child restraint with your
knee to compress the vehicle seat cushion
and seatback while tightening the webbing
of the anchor attachments.
5. Tighten the tether strap according to the
manufacturer’s instructions to remove any
slack.
