WARNING
●Make sure the “AIR BAG OFF” indica-
tor light is not illuminated when using
the seat belt extender for the front pas-
senger seat. If the “AIR BAG OFF”
indicator light is illuminated, discon-
nect the extender tongue from the seat
belt buckle, and reconnect the seat
belt. Reconnect the se at belt extender
after making sure the “AIR BAG ON”
indicator light is illu minated. If you use
the seat belt extender while the “AIR
BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front
passenger may not activate, which
could cause death or serious injury in
the event of a collision.
●Do not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket).
●Do not put weight on the front passen-
ger seat by putting your hands or feet
on the front passenger seat seatback
from the rear passenger seat.
●Do not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.
●Do not put objects under the front pas-
senger seat.
●Do not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “AIR BAG
OFF” indicator light to be illuminated,
which indicates that the SRS airbags
for the front passenger will not activate
in the event of a severe accident. If the
seatback touches the rear seat, return
the seatback to a position where it
does not touch the rear seat. Keep the
front passenger seatback as upright as
possible when the vehicle is moving.
Reclining the seatback excessively
may lessen the effectiveness of the
seat belt system.
●If an adult sits in the front passenger
seat, the “AIR BAG ON” indicator light
is illuminated. If the “AIR BAG OFF”
indicator is illuminated, ask the passen-
ger to sit up straight, well back in the
seat, feet on the floor, and with the seat
belt worn correctly. If the “AIR BAG
OFF” indicator still remains illumi-
nated, either ask the passenger to
move to the rear seat, or if that is not
possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a for-
ward-facing child restraint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
(  P.41)
●Do not modify or remove the front
seats.
●Do not kick the front passenger seat or
subject it to severe impact. Otherwise,
the SRS warning light may come on to
indicate a malfunction of the front pas-
senger occupant clas sification system.
In this case, contact your Lexus dealer
immediately.
●Child restraint systems installed on the
rear seat should not contact the front
seatbacks.
●Do not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.
●Do not modify or replace the uphol-
stery of the front seat.
●Do not place anything between the
console box and front passenger seat.
Otherwise, the system may not detect
the front passenger properly, leading
to improper operation of the airbags.
●Adjust the front passe nger seat so that
the head restraint does not touch the
ceiling. If the head restraint is left in
contact with the ceiling, the system
may not detect the front passenger
properly, leading to improper opera-
tion of the airbags.

Safety information for chil-
dren
Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child , until the child
becomes large enough to properly
wear the vehicle’s seat belt.
 It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the window lock switch to
avoid children operating the
power window accidentally.
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, trunk, seats
etc.
WARNING
■When children are in the vehicle
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof or other features of the
vehicle. In addition, heat build-up or
extremely cold temperatures inside the
vehicle can be fatal to children.
Child restraint systems
Before installing a child restraint
system in the vehicle, there are pre-
cautions that need to be observed,
different types of child restraint sys-
tems, as well as installation meth-
ods, etc., written in this manual.
Use a child restraint system when
riding with a small child that cannot
properly use a seat belt. For the
child’s safety, install the child
restraint system to a rear seat. Be
sure to follow the installation
method that is in the operation
manual enclosed with the restraint
system.

For safety and security
of child restraint systems.
 Prioritize and observe the warn-
ings, as well as the laws and regula-
tions for child restraint systems.
 Choose a child restraint system that
suits your vehicle and is appropriate
to the age and size of the child.
 Use a child restraint system appro-
priate for the child until the child
becomes large enough to properly
wear the vehicle’s seat belt.
■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
depending on the age and size of the
child.
●Lexus strongly urges the use of a
proper child restraint system that con-
forms to the size of the child, installed
on the rear seat. According to acci-
dent 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.
●Place one child to a child restraint sys-
tem and then secure the child with the
harness of the child restraint system.
■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.

WARNING
■When installing a child restraint sys-
tem
Observe the following when installing
child restraint system to the front passen-
ger seat if it is unavoidable. The front pas-
senger SRS 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 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 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 illumi-
nated.
If the head restraint interferes with the
installation of the ch ild restraint system,
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 th e area of the seat,
front 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 seri-
ous 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.

child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the
right-hand rear seat.
●Adjust the front passenger seat so that
it does not interfere with the child
restraint system.
●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,
rear pillars or roof side rails from which
the SRS curtain shie ld airbag deploys
even if the child is seated in the child
restraint system. It is dangerous if the
SRS curtain shield airbag inflates, and
the impact could cause death or seri-
ous injury to the child.
