WARNING
■Child restraint precautions
● Do not allow the child to lean his/her head or any part of his/ her body
against the side door or the area of the seat, front and side p illars or roof
side rail from which the SRS side airbags or curtain shield airbags 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 properly secured. If
it is not secured properly, it may cause death or serious injury to the child
in the event of a sudden stop, sudden swerve 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 passen ger com-
partment.
● If it is necessary to detach the child restraint system, remove it from the
vehicle or store it securely in the luggage compartment. This will prevent it
from injuring passengers in the event of a sudden stop, sudden swerve or
an accident.
