#
rear seat and the seat backrest are
engaged before every trip.
If the left and right seat backrests are not
engaged and locked in place, this will be shown

cluster.
& WARNING Risk of injury or death if the
permissible gross mass of the child and
child restraint system together is excee‐

#
tem together weigh more than the per‐
missible gross mass of 73 lb (33 kg ),
