4-D Unsafe Vehicle Seats
Never install this base in side-facing or rear-facing vehicle seats.
4-E Vehicle Seat Belts
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 car seats. With some vehicle seat belts, this is done with
the latch plate; with other vehicle seat belts, this is done with the
retractor.
