431-2. Child safety
1
For safety and security
tions for child restraint systems.
 Use a child restraint system until the
child becomes large enough to
properly wear the vehicle’s seat belt.
 Choose a child restraint system that
suits your vehicle and is appropriate
to the age and size of the child.
■Types of child restraint system installation methods
Confirm with the operation manual enclosed with the child restraint system about
the installation of the child restraint system.
WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●For effective protection in automobile
accidents and sudden stops, a child
must be properly restrained, using a
seat belt or child restraint system
which is correctly installed. For installa-
tion details, refer to the operation man-
ual enclosed with the child restraint
system. General insta llation instruction
is provided in this manual.
●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 crushe d against the wind-
shield or between the holder and the
interior of the vehicle.
■Handling the child restraint system
If the child re straint 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.
●Make sure you have complied with all
installation instructions provided with
the child restraint system manufac-
turer and that the system is properly
secured.
●Keep the child rest raint 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 or store it securely in the trunk.

Adjust the lumbar support to the
lowest position.
 Adjust the pelvic support

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 child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-facing child restraint
system is installed on the front passen-
ger seat.
●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 th e 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.

4While pushing the child restraint
system down into the rear seat,
allow the shoulder belt to retract
until the child restraint system is
securely in place.
After the shoulder belt has retracted to a
point where there is no slack in the belt,
pull the belt to check that it cannot be
extended.
5After installing the child restraint
system, rock it back and forth to
ensure that it is installed securely.

1 Adjust the seat
When using the front passenger seat: If
installing the child rest raint system to the
front passenger seat is unavoidable, refer
to P.44 for front passenger seat adjust-
ment.
2 Place the child restraint system on
the seat facing the front of the vehi-
cle. 3
Run the seat belt through the child
restraint system and insert the plate
into the buckle. Make sure that the
belt is not twisted.
4 Fully extend the shoulder belt and
allow it to retract to put it in lock
mode. In lock mode, the belt cannot
be extended.
5 While pushing the child restraint
system into the rear seat, allow the
shoulder belt to retract until the
child restraint system is securely in
place.

strap, follow the child restraint man-
ufacturer’s operation manual
regarding the installation, using the
top tether strap to latch onto the
top tether strap anchor. ( P.51)

Booster type
High back type
3 Sit the child in the child restraint
system. Fit the seat belt to the child
restraint system according to the
manufacturer’s in structions and
insert the plate into the buckle.
Make sure that the belt is not
twisted.
Check that the shoulder belt is correctly
positioned over the child’s shoulder and
that the lap belt is as low as possible.
(  P.24)
■Removing a child restraint system
installed with a seat belt
Press the buckle release button and
fully retract the seat belt.
When releasing the buckle, the child
restraint system may sp ring up due to the
rebound of the seat cushion. Release the
buckle while holding down the child
restraint system.
Since the seat belt auto matically reels itself,
slowly return it to the stowing position.

■Child restraint LATCH anchors
LATCH anchors are provided for the
outboard rear seat. (Marks displaying
the location of the anchors are
attached to the seats.)
WARNING
■When installing a child restraint sys-
tem
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●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 inju-
ries that could result in death.
If this occurs and the buckle cannot be
unfastened, scissors should be used to
cut the belt.
●Ensure that the belt and plate are
securely locked and the seat belt is not
twisted.
●Shake the child restraint system left
and right, and forward and backward
to ensure that it has been securely
installed.
●After securing a child restraint system,
never adjust the seat.
●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.
●Follow all installation instructions pro-
vided by the child restraint system
manufacturer.
●When securing some types of child
restraint systems in rear seats, it may
not be possible to properly use the
seat belts in position s next to the child
restraint without interfering with it or
affecting seat belt effectiveness. Be
sure your seat belt fits snugly across
your shoulder and low on your hips. If it
does not, or if it interferes with the
child restraint, move to a different posi-
tion. Failure to do so may result in
death or serious injury.
■When installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fu lly extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. ( P.26)
■Do not use a seat belt extender
If a seat belt extender is used when
installing a child restra int system, the seat
belt will not securely hold the child
restraint system, which could cause
death or serious injury to the child or
other passengers in the event of sudden
braking, sudden swerving or an accident.

Observe the following precautions.
Failure to do so may result in death or
serious injury.
●When using the LATCH anchors, be
sure that there are no foreign objects
around the anchors and that the seat
belt is not caught behind the child
restraint system.
●Follow all installation instructions pro-
vided by the child restraint system
manufacturer.
●When securing some types of child
restraint systems in rear seats, it may
not be possible to properly use the
