If the seating position does not have an
adjustable head restraint and it is interfering
with the proper child restraint fit, try another
seating position or a different child restraint.
4. Route the seat belt tongue through the child
restraint and insert it into the buckle until you
hear and feel the latch engage. Be sure to
follow the child restraint manufacturer’s in-
structions for belt routing.
If the child restraint is equipped with a top
tether strap, route the top tether strap and
secure the tether strap to the tether anchor
point. See “Installing top tether strap” in this
section. Do not install child restraints that
require the use of a top tether strap to seat-
ing positions that do not have a top tether
anchor.
5. Pull the shoulder belt until the belt is fully
extended. At this time, the seat belt retractor
is in the Automatic Locking Retractor (ALR)
mode (child restraint mode). It reverts to the
Emergency Locking Retractor (ELR) mode
when the seat belt is fully retracted.
