CAUTION
!
S After inserting the tab, make sure
the tab and buckle are locked and
that the lap belt is not twisted.
S Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tab and
buckle.
S If the seat belt does not function
normally, it cannot protect your
child from injury. Contact your To-
yota dealer immediately. Do not
use the seat until the seat belt is
fixed.
2. While pressing the convertible seat
firmly against the seat cushion and
seatback, tighten the lap belt by pulling
its free end to hold the convertible seat
securely.
