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 depending on the age
and size of the child.
●Lexus strongly urges the use of a proper ch ild restraint system that conforms to the
size of the child, installed on the rear seat. According to accident statistics, the child is
safer when properly restrained in th e rear seat than in the front seat.
●Holding a child in your or someone else’s ar ms is not a substitute for a child restraint
system. In an accident, the child can be crushed against the windshield or between
the holder and the interior of the vehicle.
●Place one child to a child restraint system and then secure the child with the harness
of the child restraint system.
■Handling the child restraint system
If the child restraint system is not properly fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerv-
ing, or an accident.
●If the vehicle were to receive a strong impact from an accident, etc., it is possible that
the child restraint system has da mage that is not readily visible. In such cases, do not
reuse the restraint system.
●Make sure you have complied with all installa tion instructions provided with the child
restraint system manufacturer and th at the system is properly secured.
●Keep the child restraint system properly secure d on the seat even if it is not in use. Do
not store the child restraint system un secured in the passenger compartment.
●If it is necessary to detach the child rest raint system, remove it from the vehicle or
store it securely in the trunk.

WARNING
■When installing a child restraint system
Observe the following when installing child re straint system to the front passenger seat
if it is unavoidable. The front passenger SR S airbag inflates with considerable speed
and force that if not observed may lead to death or serious injury to the child.
●Never install a rear-facing child restraint sy stem on the front passenger seat even if
the “AIR BAG OFF” indicator lig ht is illuminated. In the event 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 installed 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.
●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 pillars or roof side rails from which the SRS side air-
bags 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.
●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.
●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 restraint system on the front
passenger seat, adjust the seatback to the
most upright position, move the seat to the
rearmost position, and raise the seat to the
highest position, even if the “AIR BAG OFF”
indicator light is illuminated.
If the head restraint interferes with the instal-
lation of the child re straint system, and the
head restraint can be removed, remove the
head restraint.

WARNING
■When installing a child restraint system
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 chokin g or other serious injuries that could result
in death. If this occurs and the buckle can not 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 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.
●Follow all installation instructions provided by the child restraint system manufacturer.
■When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten only. This could cause injury or discomfort to
the child. (P. 36)
■Do not use a seat belt extender
If a seat belt extender is used when insta lling a child restraint 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.
