a shoulder belt over each shoulder.

CAUTION
When the built−in child restraint is
in use, do not use the adult lap and
shoulder belt instead of the built−in
child restraint seat belt as it can
cause death or severe injury to the
child in a sudden stop or crash.

the tabs and buckle are locked and
that the shoulder belts and buckle
strap are not twisted.
Do not insert coins, clips, etc. in
the buckle as this may prevent you
from properly latching the tabs and
buckle.

normally, it cannot protect your
child from injury. Contact your
Toyota dealer immediately. Do not
use the built−in child restraint until
the seat belt is fixed.

shoulder belts positioned correctly on the
shoulders.
CAUTION
An unfastened shoulder belt clip will
not keep the belts on the child’s
shoulders. In a sudden stop or crash,
the child may go too far forward and
be seriously injured. Make sure the
belt clip is fastened at all times.
