While pushing the child restraint
system down into the rear seat,
allow the shoulder belt to retract
until the child seat is securely in
place.
After the shoulder belt has
retracted to a point where there is
no slack in the belt, pull the belt to
check that it cannot be extended.
Place the child restraint system on
the seat facing the front of the vehi-
cle.
Run the seat belt through the child
restraint system and insert the
plate into the buckle. Make sure
that the belt is not twisted.
Fully extend the shoulder belt and
allow it to retract to put it in lock
mode. In lock mode, the belt can-
not be extended.
