Fully extend the shoulder belt and
then allow it to retract slightly in
order to activate the ALR lock
mode.
Lock mode allows the seat belt to
retract only.
While pushing the infant seat/con-
vertible seat down into the seat,
allow the shoulder belt to retract
until the infant seat/convertible
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.
