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.
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 “RSCA OFF” indicator light is off. The
curtain shield airbags will not inflate in a vehicle
rollover if this indicator light is on and you may be
killed or seriously injured. For details, see “Roll
sensing of curtain shield airbags off switch” on page
174. Do not allow anyone to get his/her head closer 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
and curtain shield airbag inflate, the cupholder or any
other device or object will be thrown with great force,
or the side airbag and curtain shield 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.

The “AIRBAG OFF” indicator lights will be illuminated
when the ignition switch is in the “ON” position and a child
or child restraint system is in the front passenger seat (see
tablecondition 2). This indicates that in the event of a
severe frontal or passenger’s side impact, the front
passenger airbag and side airbag on the front passenger
seat are deactivated and will not deploy. If the front passenger occupant classification system
determines that a person of adult size sits in the front
passenger seat but the “AIRBAG OFF” indicator light is
illuminated, one of the following is likely to have occurred:

The rear passenger lifts the front passenger seat cushion
with their legs.
 Objects are placed under the front passenger seat.
 A front passenger seat seatback is in contact with a rear
seat.
To ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not occur.
Make sure the “AIRBAG ON” indicator light is illuminated when
an adult sits in the front passenger seat. If the “AIRBAG OFF”
indicator light is illuminated, ask the passenger to sit up
straight, well back in the seat, and with the seat belt worn
correctly. If the “AIRBAG OFF” indicator light still remains
illuminated, either ask the passenger to move to the rear seat,
or if that is not possible, move the front passenger seat fully
rearward.

3: Never install a rear −facing child restraint system on the front passenger seat. A forward −facing child restraint system should
only be installed on the front passenger seat when it is unavoidable. (See “Child restraint system” on page 176 as for installing
the child restraint system.)

If an adult sits in the front passenger seat, the
“AIRBAG ON” indicator light should be illuminated.
If the “AIRBAG 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 “AIRBAG OFF” indicator still remain illuminated,
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 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 “Child restraint system” on
page 176.)
 Do not remove the seat.
 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 detection
system. In this case, contact your Lexus dealer
immediately.
 Child restraint systems installed on the rear seat
should not contact the front seatbacks.In addition to the precautions outlined above, the “AIRBAG
ON” indicator light may be illuminated when a child sits in the
front passenger seat or a forward −facing child restraint system
is installed on the front passenger seat. If the “AIRBAG OFF”
indicator light is not illuminated in these circumstances, the
front passenger airbag and side airbag on the front passenger
side are in an activated condition — the airbags will deploy if
an impact meets the deployment criteria. Refer to all the
cautions in this Section and “Child restraint system” on page
176.

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 131 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 system 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.
 Never install a rearfacing child restraint system on
the front passenger seat even if the “AIRBAG 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 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 “AIRBAG OFF”
indicator light is illuminated, because the front
passenger airbag could inflate with considerable
speed and force. Otherwise, the child may be killed
or seriously injured.
 On vehicles with side airbags and curtain shield
airbags, 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/or
curtain shield airbags inflate, and the impact could
cause death or serious injury to the child.

OCCUPANT RESTRAINT SYSTEMS

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
sudden 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 i nstructions 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 system 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 192.
The child restraint lower anchorages approved for your vehicle
may also be used. See “Installation with child restraint lower
anchorages” on page 194.

An infant seat must be used in rearfacing position only.
CAUTION

Never install a rearfacing child restraint system on
the front passenger seat even if the “AIRBAG OFF”

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.
