For the safety of a child, install child restraint systems to second-row seats.
When installing child restraint system to a front passenger seat is unavoidable,
adjust the seat as follows and install the child restraint system. ●
Raise the seatback as much as
possible ●
Move the seat to the rearmost
position ●
Raise the seat to the highest posi-
tion ●
If the head restraint interferes
with the installation of the child
restraint system, and the head
restraint can be removed, remove
the head restraint If the head restraint cannot be removed, raise it to the uppermost position.When using a child restraint system
WARNING ■
When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or serious injury.●
Never install a rear-facing ch ild restraint system on the front passenger seat even if
the “AIR BAG OFF” indicator lig ht is illuminated. In the even t of an accident, the force
of the rapid inflation of the front passenger airbag can cause death or serious injury to
the child if the rear-facing ch ild restraint system is inst alled on the front passenger
seat. ●
A forward-facing child restraint system ma y be installed on the front passenger 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.

RX450h_RX450hL _U_OM48F85UWARNING ■
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.
