4-D Vehicle Seat Belts
Review your vehicle owner's manual for vehicle seat
belt use
This base can be installed using a vehicle seat belt. To do this,
you will need to change the seat belt to a locked mode for use
with a base. With some vehicle seat belts, this is done with the
latch plate; with other vehicle seat belts, this is done with the
retractor.
