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.
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 crushed 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 lug-
gage compartment.

■When installing a child restraint
system to a front passenger seat
For the safety of a child, install child
restraint systems to a rear seats. When
installing child restraint system to a
front passenger seat is unavoidable,
adjust the seat as follows and install the
child restraint system.
 Move the front seat fully rearward. If
the passenger seat height can be
adjusted, move it to the upper most
position.
 Adjust the seatback angle to the
most upright position. When install-
ing a forward-facing child seat, if
there is a gap between the child seat
and the seatback, adjust the seat-
back angle until good contact is
achieved.
When installing a forward-facing child
seat, if there is a gap between the child seat
and the seatback, adjust the seatback
angle until good contact is achieved.
If the head restraint interferes with
your child restraint system, and the
head restraint can be removed,
remove the head restraint. Other-
wise, put the head restraint in the
upper most position.
When using a child restraint sys-
tem
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.

521-2. Child safety
LEXUS NX300 Owners Manual_USA_M78389_en
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.
When installing a forward-facing child
restraint system on the front passenger
seat, move the seat as far back as pos-
sible, and raise the seat to the upper
most position, even if the “AIR BAG
OFF” indicator light is illuminated. If
the head restraint interferes with the
child restraint system installation and
the head restraint can be removed,
remove the head restraint.
●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 airbags and curtain shield air-
bags 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.

■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 spring up due to the
rebound of the seat cushion. Release the
buckle while holding down the child
restraint system.
Since the seat belt automatically reels itself,
slowly return it to the stowing position.
WARNING
■When installing a child restraint sys-
tem
Observe the following precautions. Fail-
ure to do so may result in death or seri-
ous 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 child restraint system
in the rear center seat, adjust both
seatbacks at the same angle. Other-
wise, the child restraint system cannot
be securely restrained and this may
cause death or serious injuries in the
event of sudden braking, sudden
swerving or an accident.
■When installing a booster seat
To prevent the belt from going into ALR
lock mode, do not fully extend the shoul-
der belt. ALR mode causes the belt to
tighten only. This could cause injury or
discomfort to the child. ( P.28)
■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.
