The SRS side airbag on the passenger seat will not activate if
there is no passenger sitting in the front passenger seat.
However, the side airbag on the passenger seat may deploy
if luggage is put in the seat, or the seat belt is buckled up
regardless of
the presence of the occupant in the seat. (As for
the front passenger occupant classification system, see “Front
passenger occupant classification system” on page 157.)
Roll sensing function:
In response to a vehicle rollover, the curtain shield airbags on
both sides inflate. The curtain shield airbags work together
with the seat belts to help to reduce injuries mainly to the
driver’s head, front passenger’s head and second seat
passengers’ heads and can help the driver, front passenger
and second seat passengers to retain inside the vehicle.
The SRS curtain shield airbag on the passenger side is
activated even with no passenger in the front seat or second
seat.
The SRS curtain shield airbags may activate even when the
side airbags are not activated.
Always wear your seat belt properly.
CAUTION
 The SRS side airbag and curtain shield airbag system
is designed only as a supplement to the primary
protection of the driver, front and second outboard
seat passenger seat belt systems. The front and
second seat occupants can be killed or seriously
injured by the inflating airbags if they do not wear the
available seat belts properly . During sudden braking
just before a collision, an unrestrained driver, front
passenger or second seat passenger can move
forward or sideways into direct contact with or close
proximity to the airbag which may then deploy during
the collision. To ensure maximum protection in an
accident, the driver and all passengers in the vehicle
must wear their seat belts properly. Wearing a seat
belt properly during an accident reduces the chances
of death or serious injury or being thrown out of the
vehicle. For instructions and precautions
concerning the seat belt system, see “Seat belts” on
page 121.
 Do not allow anyone to lean his/her head or any part
of his/her body against the door or the area of the
seat, front pillar, rear pillar or roof side rail from which
the SRS side airbag and curtain shield airbag deploy
even if he/she is a child seated in the child restraint
system. It is dangerous if the SRS side airbag and
curtain shield airbag inflate, and the impact of the
deploying airbags could cause death or serious
injury to the occupant.

Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. 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 seat of the vehicle and properly restrained.
The rear seats are the safest for infants and children.
For instructions concerning the installation of a child
restraint system, see “Child restraint” on page 162.

 Roll sensing of curtain shield airbags off switch
The roll sensing of curtain shield airbags off switch can
turn off the curtain shield airbags in a vehicle rollover.
This switch should only be used in a situation where the
inflation is not desired (such as during extreme offroad
driving).
When you push the roll sensing of curtain shield airbags off
switch for a few seconds with the ignition switch on, the roll
sensing of curtain shield airbags off indicator light comes on
and the roll sensing function is turned off. When you push the
switch again, the indicator light goes off and the roll sensing
function is turned on.
In a severe side impact, the curtain shield airbag on the
impacted side will inflate even if the roll sensing function is
turned off.
If the ignition switch is turned to “ACC” or “LOCK” with the r\
oll
sensing function off and then the ignition switch is turned back
to “ON”, the roll sensing function will be back on automatically.

CAUTION
SRS side airbags and curtain shield airbags inflate with
considerable force. To reduce the possibility of death
or serious injury when they inflate, the driver, front
passenger and rear outboard passengers must:
Wear their seat belts properly.
 Remain properly seated with their backs upright and
against the seats at all times.
16x520a
Do not allow anyone to lean against the door when
the vehicle is in use, since the side airbag and curtain
shield airbag could inflate with considerable speed
and force. Otherwise, he/she may be killed or
seriously injured. Special care should be taken
especially when you have a small child in the vehicle.
 Sit up straight and well back in the seat, distributing
your weight evenly in the seat. Do not apply
excessive weight to the outer side of the seats with a
side airbag,and to the front pillar, rear pillar, and roof
side rail with a curtain shield airbag.
 Improper sitting and wearing of the seat belts may
not retain you inside the vehicle.

Make sure the roll sensing of curtain shield airbags
off indicator is not on. If this indicator light is on, the
curtain shield airbags will not inflate in a vehicle
rollover and you may be killed or seriously injured.
16x522a
Do not allow anyone to get his/her head close to the
area where the side airbag and curtain shield airbag
inflate, since these airbags could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.
 Do not allow anyone to kneel on the passenger seat,
facing the passenger’s side door, since the side
airbag and curtain shield airbag could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.

Do not allow anyone to get his/her head or hands out
of windows since the curtain shield airbags could
inflate with considerable speed and force. Otherwise,
he/she may be killed or seriously injured. Special
care should be taken especially when you have a
small child in the vehicle.

 Do not attach a cupholder or any other device or
object on or around the door. When the side airbag
inflates, the cupholder or any other device or object
will be thrown with great force, or the side airbag may
not activate correctly, resulting in death or serious
injury. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.

CAUTION
To avoid potential death or serious injury when the front
passenger occupant classification system does not
detect the conditions correct ly, observe the following:
Make sure the front passenger occupant
classification indicator light indicates “ON” when
using the seat belt extender for the front passenger
seat. If the indicator light indicates “OFF”,
disconnect the extender t ongue from the seat belt
buckle, then reconnect the seat belt. Reconnect the
seat belt extender after making sure the indicator
light indicates “ON”. If you use the seat belt extender
while the indicator light indicates “OFF”, the front
passenger airbag and side airbag on the front
passenger side may not ac tivate correctly, which
could cause death or serious injury in the event of
collision.
Do not recline the front passenger seatback so far
that it touches a rear seat. This may cause the “OFF”
indicator to be illuminated, which indicates that the
passenger’s airbags will not deploy in the event of a
severe accident. If the seat back touches the second
seat, return the seatback to a position where it does
not touches the second 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
occupant classification indicator light should
indicate “ON”. If the “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
correctly. If the “OFF” indicator still remains
illuminated, either ask the passenger to move to the
second seat, or if that is not possible, move the front
passenger seat fully rearward.
Wear the seat belt properly.
Make sure the front passenger’s seat belt tab has not
been left inserted into the buckle before someone sits
in the front passenger seat.
Do not apply a heavy load to the front passenger seat
or equipment (e.g. armrest).
Do not put weight on the front passenger seat by
putting your hands or feet on the front passenger
seatback from the second seat.
Do not let a second seat passenger lift the front
passenger seat with their feet or press on the
seatback with their legs.
Do not put objects under the front passenger seat.
 Do not modify or replace the upholstery of the front seat.
Child restraint systems inst alled on the second seat
should not contact the front seatbacks.

When it is unavoidable to install the forwardfacing
child restraint system on the front passenger seat,
install the child restraint system on the front
passenger seat in the proper order. (As for the
installation order, see “Ins tallation with 3point type
seat belt” on page 171.)
Do not remove the front seats.
Do not kick the front passe nger seat or subject it to
severe impact. Otherwise, the SRS warning light may
come on to indicate a malfunction of the detection
system. In this case, cont act your Toyota dealer
immediately.
The front passenger occupant classification indicator light may
indicate “ON” when a child sits in, or a forward −facing child
restraint system is installed on the front passenger seat. If the
“OFF” indicator is not illuminated in these circumstances, the
front passenger airbag and side airbag on the front passenger
side are in an active condition—the airbags will deploy if an
impact meets the deployment criteria. Refer to all the cautions
in this section, and “Child restraint” that follows.
CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of appropriate child
restraint systems for children.
The laws of all 50 states in the U.S.A. and Canada now require
the use of a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child should
sit in the rear seat and must be restrained using the vehicle’s
seat belt. See “Seat belts” on page 121 for details.
CAUTION
 For effective protection in automobile accidents and
sudden stops, a child must be properly restrained,
using a seat belt or child restraint depending on age
and size of the child. Holding a child in your arms is
not a substitute for a child restraint system. In an
accident, the child can be crushed against the
windshield, or between you and the vehicle’s interior.
 Lexus strongly urges use of a proper child restraint
system which 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.

OCCUPANT RESTRAINT SYSTEMS

Never install a rearfacing child restraint system on
the front passenger seat even if the front passenger
occupant classification indicator light indicates
“OFF”. 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
rearfacing child restraint system is installed on the
front passenger seat.
 A forwardfacing child restraint system should be
allowed to be installed on the front passenger seat
only when it is unavoidable. Always move the seat
as far back as possible even if the front passenger
occupant classification indicator light indicates
“OFF”, because the front passenger airbag could
inflate with considerable speed and force. Otherwise,
the child may be killed or seriously injured. 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 pillar or roof side rail from which the
side airbags or curtain shield airbags deploy even if
the child is seated in the child restraint system. It is
dangerous if the side airbags and curtain shield
airbags inflate, and the impact could cause death or
serious injury to the child.
 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 collision.
 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
stop or accident.

Child restraint system
A child restraint system for a small child or baby must
itself be properly restrained on the seat with the lap
portion of the lap/shoulder belt. You must carefully
consult the manufacturer’s instructions which
accompany the child restraint system.
To provide proper restraint, use a child restraint system
following the manufacturer’s instructions about the
appropriate age and size of the child for the child restraint
system.
Install the child restraint system correctly following the
instructions provided by its manufacturer. General directions
are also provided under the following illustrations.
The child restraint system should be 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.
When not using the child restraint system, keep it secured with
the seat belt or place it somewhere other than the passenger
compartment. This will prevent it from injuring passengers in
the event of a sudden stop or accident.
Types of child restraint system
Child restraint systems are classified into the following 3 types
depending on the child’s age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint syst em following the instructions
provided by its manufacturer.
Your vehicle has anchor brackets for securing the top strap of
a child restraint system.
For instructions about how to use the anchor bracket, see
“Using a top strap” on page 184.
The child restraint lower anchorages approved for your vehicle
may also be used. See “Installation with child restraint lower
anchorages” on page 186.
