CAUTION
■SRS airbag precautions
●The SRS front passenger airbag also deploys with considerable force, and can
cause death or serious injury especially if the front passenger is very close to the
airbag. The front passenger seat should be as far from the airbag as possible with
the seatback adjusted, so the front passenger sits upright.
●Improperly seated and/or restrained infants and children can be killed or seri-
ously injured by a deploying airbag. An infant or child who is too small to use a
seat belt should be properly secured using a child restraint system. Lexus strongly
recommends that all infants and children be placed in the rear seats of the vehicle
and properly restrained. The rear seats are the safest for infants and children.
(→ P. 1 2 2 )
●If the seat belt extender has been con-
nected to the front seat belt buckles but the
seat belt extender has not also been fas-
tened to the latch plate of the seat belt, the
SRS front airbags will judge that the driver
and front passenger are wearing the seat
belt even though the seat belt has not been
connected. In this case, the SRS front
airbags may not activate correctly in a colli-
sion, resulting in death or serious injury in
the event of a collision. Be sure to wear the
seat belt with the seat belt extender.

CAUTION
■Child restraint precautions
●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 statistics, the
child is safer when properly restrained in the rear seat than in the front seat.
●Never install a rear facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light is illuminated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous injury to the child if the rear facing child restraint system is installed on the
front passenger seat.
●A forward facing child restraint system should be allowed to 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. Adjust the
seatback as upright as possible and always move the seat as far back as possible
even if the “AIR BAG OFF” indicator light is illuminated, because the front pas-
senger airbag could inflate with considerable speed and force. Otherwise, the
child may be killed or seriously injured.
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, 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 a sudden stop, sudden swerve or an accident.
●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 from which the side airbags deploy even if the child is
seated in the child restraint system. It is dangerous if the side 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 an 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 restraint 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. This will prevent it from injuring passengers in the
event of a sudden stop, sudden swerve or accident.

■When installing a child restraint system with lower anchors and a top tether strap
Depending on the child restraint system's size and shape, if the child restraint sys-
tem is installed to the LATCH anchors first, it may not be possible to attach the top
tether strap to the anchor bracket.
In that case, first temporarily attach the top tether strap to the anchor bracket, install
the child restraint system using the lower anchors and then tighten the top tether
strap.
■Laws and regulations pe rtaining to anchorages
The LATCH system conforms to FMVSS225 or CMVSS210.2.
Child restraint systems conforming to FMVSS213 or CMVSS213 specifications
can be used.
This vehicle is designed to conform to the SAE J1819.
