FORD 2012 F-550 v.3 - Manual (Page 216)

Types of booster seats
There are generally two types of belt-positioning booster seats: backless
and high back. Always use booster seats in conjunction with the vehicle
lap/shoulder belt.
• Backless booster seats
If your backless booster seat has a
removable shield, remove the
shield. If a vehicle seating position
has a low seat back or no head
restraint, a backless booster seat
may place your child’s head (as
measured at the tops of the ears)
above the top of the seat. In this
case, move the backless booster
to another seating position with a
higher seat back or head restraint and lap/shoulder belts, or consider
using a high back booster seat.
• High back booster seats
If, with a backless booster seat,
you cannot find a seating position
that adequately supports your
child’s head, a high back booster
seat would be a better choice.
