7 Gently pull up on the harness straps
to tighten the lap section of the harness,
which should fit low on the child's body .
8 Slowly pull the adjuster strap to tighten
the harness around the child (Fig. E) .
IMPORTANT: Snugly adjust the belts
provided with this child restraint around
your child . A snug strap should not
allow any slack . It lies in a relatively
straight line without sagging . It does
not press on the child's flesh or push the
child's body into an unnatural position .
9 Position the chest clip at the middle
of the child's chest, level with the child's
armpit (Fig. F) .
10 Verify that harness is not twisted and
child is properly secured .
11 See Checking Harness Height on
page 30 .
IMPORTANT:
• Always pull on the harness after securing
the child to make sure the buckle and
harness are locked. If not, the buckle
or adjuster area may be clogged with
food, drink, or objects that need to be
removed. See pages 33 and 35 for cleaning
instructions.
• Always make sure that the harness is tight
before each use, or after any adjustments.
