The indicator comes on when the ignition key is turned to
the ONº position. It goes off after about 6 seconds. This
means the SRS side airbags and curtain shield airbags are
operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver's seat position sensor, driver's seat belt buckle switch,
front seat b elt pretensioner assemblies, inflators, warning light,
RSCA OFFº indicator light, interconnecting wiring and power
sources. (For details, see Service reminder indicators and
warning buzzersº on page 52 for instructions.) If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.

When the ignition key is turned to the ONº position, the light
does not come on, remains on or flashes.
 The light comes on or starts flashing while driving.
If the light stays on, it indicates that the SRS front airbags have
a problem. If the light flashes, the SRS side and curtain shield
airbags have a problem.

 The portion of the doors (shaded in the illustration) was
involved in an accident that was not severe enough to cause
the SRS side airbags and curtain shield airbags to inflate.
 The surface of the seats with the side airbag (shaded in the
illustration) is scratched, cracked, or otherwise damaged.
 The portion of the front pillars, rear pillars or roof side rail
garnishes (padding) containing the curtain shield airbags

Roll sensing of curtain shield airbags off
switch
The roll sensing of curtain shield airbags off switch
(RSCA OFFº switch) can turn off the curtain shield
airbags and seat belt pretensioners in a vehicle rollover.
This switch should only be used if inflation is not desired
(such as extreme off-road driving).
When you push the RSCA OFFº switch for a few seconds with
the ignition switch on, the RSCA OFFº 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. (For details about the roll sensing
function, see SRS side airbags and curtain shield airbagsº on
page 168.) In a severe side impact, the curtain shield airbags on impacted
side will inflate even if the roll sensing function is turned off.
(For details about the curtain shield airbags, see SRS side
airbags and curtain shield airbagsº on page 168.)
In a severe frontal impact, the seat belt pretensioners will work
even if the roll sensing function is turned off. (For details about
the seat belt pretensioners, see ÐSeat belt pretensionersº on
page 150.)
If the ignition switch is turned to ACCº or LOCKº with the roll
sensing
function off and then the ignition switch is turned back
to ONº, the roll sensing function will turn back on
automatically.CAUTION
 Before normal driving, make sure the RSCA OFFº
indicator light is off.
 When the roll sensing function is turned off (and the
RSCA OFFº indicator light is on), the curtain shield
airbags and seat belt pretensioners will not work in
a vehicle rollover. Turning off the curtain shield
airbags and seat belt pretensioners reduces
occupant protection which your vehicle safety
systems can provide in accidents and increase the
likelihood of death or serious injuries.

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 beltsº on page 140 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
185
Never install a rear-facing child restraint system on
the front passenger seat. 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, 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
186
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
Using a top strapº on page 202.
The child restraint lower anchorages approved for your vehicle
may also be used. See Installation with child restraint lower
anchoragesº on page 205.

(A) Infant seat installation
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. 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.

OCCUPANT RESTRAINT SYSTEMS
189
If the driver's seat position does not allow sufficient
space for safe installation, install the child restraint
system on the second right seat.
Align both third seatbacks at the same angle
When installing a child restraint system in the third
center position, align both seatbacks at the same
angle. Otherwise, the child restraint system cannot
be securely restrained and this may cause death or
serious injuries in a collision.

1. Run the lap and shoulder belt through or around the infant
seat following the instructions provided by its manufacturer
and insert the tab into the buckle taking care not to twist the
belt. Keep the lap portion of the belt tight.
CAUTION
After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt are not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent your child from properly latching the tab
and buckle.
 If the seat belt does not function normally, it cannot
protect your child from death or serious injury.
Contact your Lexus dealer immediately. Do not
install the child restraint system on the seat until the
seat belt is fixed.
2. Fully extend the shoulder belt to put it in the lock mode.
When the belt is then retracted even slightly, it cannot be
extended.
To hold the infant seat securely, make sure the belt is in the lock
mode before letting the belt retract.
