RX350/RX350L_U WARNING ■
When using a child restraint system
If the head restraint interferes with the inst allation of the child restraint system, and the
head restraint can be removed, remove the head restraint.
If the head restraint cannot be remove d, raise it to the uppermost position.
●
When a booster seat is installed, always en sure that the shoulder belt is positioned
across the center of the child’s shoulder. The belt should be kept away from the child’s
neck, but not so that it coul d 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. ●
A forward-facing child restraint system may
be installed on the front passenger seat only
when it is unavoidable. When installing a for-
ward-facing child restrain t system on the front
passenger seat, raise the seatback as much as
possible, move the seat to the rearmost posi-
tion, and raise the seat to the highest position,
even if the “AIR BAG OFF” indicator light is
illuminated. ●
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 air-
bags or SRS curtain shield airbags deploy
even if the child is seat ed in the child restraint
system. It is dangerous if the SRS side airbags
and curtain shield airbags inflate, and the
impact could cause death or serious injury to
the child.
●
If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, atta ch the child restraint
system to the right-hand rear seat. ●
Adjust the front passenger seat so that it does
not interfere with the child restraint system.
