WARNING
●Lexus strongly urges the use of a proper child restraint system that con-forms to the weight and size of the
child, installed on the rear seat. According to accident statistics, the child is safer when properly restrained
in the rear seat than in the front seat.
●Holding a child in your or someone else’s arms is not a substitute for a child restraint system. In an accident, the
child can be crushed against the wind- shield or between the holder and the interior of the vehicle.
■Handling the child restraint system
If the child restraint system is not prop- erly fixed in place, the child or other pas-
sengers may be seriously injured or even killed in the event of sudden braking, sud- den swerving, or an accident.
●If the vehicle were to receive a strong
impact from an accident, etc., it is pos- sible that the child restraint system has damage that is not readily visible. In
such cases, do not reuse the restraint system.
●Depending on the child restraint sys-tem, installation may be difficult or
impossible. In those cases, check whether the child restraint system is suitable for installment in the vehicle.
( P.54, 57) Be sure to install and observe the usage rules after carefully reading the child restraint system fixing
method in this manual, as well as the operation manual enclosed with the child restraint system.
●Keep the child restraint system prop-
erly secured on the seat even if it is not in use. Do not store the child restraint system unsecured in the passenger
compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle.

WARNING
●Never use a rear-facing child restraint system on the front passenger seat when the airbag manual on-off switch
is on. ( P.46) The force of the rapid inflation of the front passenger airbag can cause
death or serious injury to children in the event of an accident.

WARNING
WARNING
■When installing a child restraint sys-
tem
●Only put a forward-facing child
restraint system on the front seat when unavoidable. When installing a for-
ward-facing child rest raint on the front passenger seat, move the seat as far back as possible. Failing to do so may
result in death or serious injury if the airbags deploy (inflate).
●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 or rear pillars or roof side rails from which the SRS side airbags or
SRS curtain shield airbags deploy even if the child is seated in the child restraint system. It is dangerous if the
SRS side and curtain shield airbags inflate, and the impact could cause death or serious injury to the child.
●When a junior seat is installed, always ensure that the shoulder belt is posi-
tioned across the center of the child’s shoulder. The belt should be kept away from the child’s neck, but not so that it
could fall off the child’s shoulder.
●Use child restraint system suitable to the age and size of the child and install it to the rear seat.
