491-2. Child safety
LS500_OM_OM50F54U_(U) 1
For safety and security
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt. ■
Installing child restraint system
using a seat belt (child restraint
lock function belt)
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.WARNING●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint system that requires a
top tether strap should not be used in
the front passenger seat since there is
no top tether strap anchor for the front
passenger seat.●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, adjust the seatback angle to the
most upright position, move the seat to
the rearmost position, and raise the
seat to the upper most 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 airbags or
SRS curtain shield ai rbags 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 booster seat is installed,
always ensure that th e 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 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. ●
If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the
right-hand rear seat.
●
Adjust the front passe nger seat so that
it does not interfere with the child
restraint system.
