621-1. For safe use
WARNING
■Child restraint precautions
● Do not use the seat belt extender when installing a child restr aint system
on the front or rear passenger seat. If installing a child rest raint system
with the seat belt extender connected to the seat belt, the seat belt will not
securely hold the child restraint system, which could cause dea th or seri-
ous injury to the child or other passengers in the event of an accident.
● Do not allow the child to lean his/her head or any part of his/ her body
against the door or the area of the seat, front and rear pillar s or roof side
rails from which the SRS side airbags or SRS curtain shield air bags deploy
even if the child is seated in the child restraint system. It is dangerous if
the SRS side airbags and curtain shield airbags inflate, and th e impact
could cause death or serious injury to the child.
● Make sure you have complied with all installation instructions provided by
the child restraint manufacturer and that the system is properl y secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop or an accident.
■ When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes
twisted around a child’s neck, it may lead to choking or other serious injuries
that could result in death.
If this occurs and the buckle cannot be unfastened, scissors sh ould be used
to cut the belt.
■ When the child restraint system is not in use
● Keep the child restraint system properly secured on the seat ev en if it is
not in use. Do not store the child restraint system unsecured in the pas-
senger compartment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle. This will prevent it from injuring passengers in the event of a sud-
den stop or an accident.
