Make sure the ªRSCA OFFº 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 ªRoll
sensing of curtain shield airbags off switchº on page
199. 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.

FRONT PASSENGER OCCUPANTCLASSIFICATION SYSTEM
Your vehicle is equipped with a front passenger occupant
classification system. This system detects the conditions
1 Ð 4 in the table shown below, and based on these
conditions activates or deactivates the airbags. The
system monitors the weight and load on the front
passenger seat, and the seat belt buckle switch in
determining conditions 1 Ð 4.
In order for the system to detect the conditions correctly,
do not do any of the following:
 Apply a heavy load to the front passenger seat or equipment
(e.g. armrest).
 Attach a commercial seatback table, etc. to the front
passenger seatback.
 Put weight on the front passenger seat by putting your
hands or feet on the seat seatback from the rear passenger
seat.
The ªAIRBAG OFFº indicator lights will be illuminated
when the ignition switch is in the ªONº position and a child
or child restraint system is in the front passenger seat (see
table±condition 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 an adult sits in the front passenger seat, the
ªAIRBAG ONº indicator light should be illuminated.
If the ªAIRBAG OFFº 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 ªAIRBAG OFFº 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 forward±facing
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 ªChild restraint systemº on
page 202.)
 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 ªAIRBAG
ONº 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 ªAIRBAG OFFº
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 Ð the airbags will deploy if
an impact meets the deployment criteria. Refer to all the
cautions in this Section and ªChild restraint systemº on page
202.

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 ªSeat beltsº on page 151 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.

OCCUPANT RESTRAINT SYSTEMS
201
Never install a rear±facing child restraint system on
the front passenger seat even if the ªAIRBAG OFFº
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 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. Always move the seat as
far back as possible even if the ªAIRBAG OFFº
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 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 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 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
ªUsing a top strapº on page 219.
The child restraint lower anchorages approved for your vehicle
may also be used. See ªInstallation with child restraint lower
anchoragesº on page 222.

An infant seat must be used in rear±facing position only.
CAUTION

Never install a rear±facing child restraint system on
the front passenger seat even if the ªAIRBAG OFFº
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 rear±facing child restraint system is
installed on the front passenger seat.
