For safety and security WARNING■
Front passenger occupant classifica-
tion system precautions
Observe the following precautions
regarding the front passenger occupant
classification system. Failure to do so may
cause death or serious injury. ●
Wear the seat belt properly.●
Make sure the fron t passenger’s seat
belt plate has not been left inserted
into the buckle before someone sits in
the front passenger seat.●
Make sure the “AIR BAG OFF” indi-
cator light is not illuminated when
using the seat belt extender for the
front passenger seat. If the “AIR BAG
OFF” indicator light is illuminated, dis-
connect the extender tongue from the
seat belt buckle, and reconnect the
seat belt. Reconnect the seat belt
extender after making sure the “AIR
BAG ON” indicator light is illumi-
nated. If you use the seat belt extender
while the “AIR BAG OFF” indicator
light is illuminated, the SRS airbags for
the front passenger will 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
passenger to sit up straight, well back
in the seat, feet on the floor, and with
the seat belt worn co rrectly. If the “AIR
BAG OFF” indicator still remains illu-
minated, 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 re straint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
( → P.50)
●
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.

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 rear door child-protector
lock or the window lock switch to
avoid children opening the door
while driving or operating the
power window accidentally.
( → P.109, 145)
 Do not let small children operate
equipment which may catch or
pinch body parts, such as the
power window, hood, back door,
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 (if equipped) or other fea-
tures of the vehicle. In addition, heat
build-up or extremely cold temperatures
inside the vehicle can be fatal to children.

Points to remember WARNING■
When a child is riding
Observe the following precautions. Fail-
ure to do so may result in death or seri-
ous 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 ur ges the use of a
proper child restrain t 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 restraint system is not prop-
erly fixed in place, the child or other pas-
sengers may be seriou sly 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 instruct ions provided with
the child restrain t system manufac-
turer and that the system is properly
secured.●
Keep the child restraint 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 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 passenger seat as follows
and install the child restraint system.
 Raise the seatback as much as pos-
sible
 Move the seat to the rearmost posi-
tion
 Raise the seat to the upper most
position
 If the head restraint interferes with
the child restraint system installa-
tion and the head restraint can be
removed, remove the head restraintWhen using a child restraint sys-
tem on a passenger seat 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 air bag 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-fac ing 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, 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.

good contact is achieved.WARNING●
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 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.
When using a child restraint sys-
tem on a rear seat 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 inte rfering 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.
