While pushing the child restraint
system into the rear seat, allow the
shoulder belt to retract until the
child restraint system 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 booster seat on the seat
facing the front of the vehicle.
Sit the child in the booster seat. Fit
the seat belt to the booster seat
according to the manufacturer's
instructions and insert the plate
into the buckle. Make sure that the
belt is not twisted.
Check that the shoulder belt is cor-
rectly positioned over the child's
shoulder, and that the lap belt is as
low as possible. (→ P. 109 )
