& WARNING Risk of injury or death if the
permissible gross mass of the child and
child restraint system together is excee‐
ded
For LATCH-type (ISOFIX) child restraint sys‐
tems in which the child is secured using the
integrated seat belt integrated in the child
restraint system, the permissible gross mass
of the child and child restraint system is
73 lb (33 kg).
If the child and the child restraint system
together weigh more than 73 lb (33 kg), the
LATCH-type (ISOFIX) child restraint system
with integrated seat belt does not offer suffi‐
cient protection. An excessive load may be
placed on the LATCH-type (ISOFIX) child seat
attachments and the child may not be
restrained in the event of an accident, for
example.
If the child and the child restraint sys‐
#
tem together weigh more than 73 lb
(33 kg), only use a LATCH-type (ISOFIX)
