WARNING:
{
Children can be seriously injured or strangled if a
shoulder belt is wrapped around their neck and
the safety belt continues to tighten. Buckle any
unused safety belts behind the child restraint so
children cannot reach them. Pull the shoulder belt
all the way out of the retractor to set the lock, if
your vehicle has one, after the child restraint has
been installed.
Notice: Do not let the LATCH attachments rub
against the vehicle's safety belts. This may damage
these parts. If necessary, move buckled safety
belts to avoid rubbing the LATCH attachments.
Do not fold the empty rear seat with a safety belt
buckled. This could damage the safety belt or
the seat. Unbuckle and return the safety belt to its
stowed position, before folding the seat.
