Studies have shown that installing a child restraint on a rear seat is much
safer than installing one on the front passenger seat.
Choose a child restraint system that suits your vehicle and is appropri-
ate to the age and size of the child.
For installation details, follow the instructions provided with the child
restraint system.
General installation instructions are provided in this manual. (P. 7 0 )
If child restraint system regulations exist in the country where you
reside, please contact any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional for the child restraint
system installation.
Lexus recommends that you use a child restraint system which con-
forms to the regulation ECE No.44.

641-1. For safe use
IS300h_EE(OM53B95E)NOTE:
*1: Adjust the front seatback to the most upright position. Move the front seat
cushion to the fully rearward.
Adjust the seat cushion to the highest position. When the child restraint sys-
tem touched the ceiling, lower the seat position.
Follow these procedures
• For installing a baby seat with support base
If the baby seat interferes with the seatback when latching the baby seat
into the support base, adjust the seatback rearward until there is no interfer-
ence.
• For installing a forward-facing child seat
If there is gap between the child seat and the seatback, tilt the seatback rear-
ward until good contact is achieved.
If the seatbelt shoulder anchor is ahead of the child seat belt guide, move
the seat cushion forward.
• For installing a junior seat
If the child in your child restraint system is in a very upright position,
adjust the seatback to the most comfortable position.
If the seat belt shoulder anchor is ahead of the child seat belt guide, move
the seat cushion forward.
*2: Remove the head restraint if it interferes with your child restraint system.
*3: When using the left side seat for the child restraint system, do not sit in the
center seat.
The child restraint system mentioned in the table may not be available
outside of the EU area.
Other child restraint systems which are different from the systems men-
tioned in the table can be used, but the suitability of the systems must be
carefully checked with the child restraint system manufacturer and
retailer.

When installing a child restraint system on the front passenger seat
Selecting an appropriate child restraint system
Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt.
If the child is too large for a child restraint system, sit the child on a rear seat
and use the vehicle’s seat belt. (P. 38) When you have to use a child restraint sys-
tem on the front passenger seat, adjust the
following:
The seatback to the most upright position
The seat cushion to the highest position
The seat cushion to the fully rearward
position
CAUTION
Using a child restraint system
The use of a child restraint system not suitable for the vehicle may not properly
secure the infant or child. It may result in death or serious injury (in the event
of sudden braking or an accident).

681-1. For safe use
IS300h_EE(OM53B95E)
CAUTION
Child restraint precautions
For effective protection in automobile accidents and sudden stops, a child
must be properly restrained, using a seat belt or child restraint system depend-
ing on the age and size of the child. Holding a child in your arms is not a sub-
stitute for a child restraint system. In an accident, the child can be crushed
against the windshield, or between you and the vehicle’s interior. This may
cause death or serious injury to the child in the event of a sudden stop, sudden
swerve or accident.
Lexus strongly urges the use of a proper child restraint system that conforms
to the size of the child, installed on the rear seat. According to accident statis-
tics, the child is safer when properly restrained in the rear seat than in the
front seat.
Never use a rear-facing child restraint system on the front passenger seat
when the airbag manual on-off switch is on. (P. 5 4 )
In the event of an accident, the force of the rapid inflation of the front passen-
ger airbag can cause death or serious injury to the child.
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. Adjust the seatback as
upright as possible and always move the seat as far back as possible because
the front passenger airbag could inflate with considerable speed and force.
Otherwise, the child may be killed or seriously injured.
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, center and 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
airbags and curtain shield airbags inflate, and the 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 accident.

CAUTION
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 should 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 even if it is not in
use. Do not store the child restraint system unsecured in the passenger com-
partment.
If it is necessary to detach the child restraint system, remove it from the vehi-
cle or store it securely in the trunk. This will prevent it from injuring passen-
gers in the event of a sudden stop, sudden swerve or accident.
