Do not place luggage heavier than specified on the
roof luggage carrier. Such luggage may cause the
curtain shield airbags and seat belt pretensioners to
inflate accidentally, which could result in death or
serious injury. For details, see Roof luggage
carrierº on page 110.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repair and modification.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS side airbag
and curtain shield airbag system in some cases.
Installation of electronic devices such as a mobile
two-way radio, cassette tape player or compact disc
player
Modification of the suspension system
Modification of the structure of the passenger
compartment
Repairs made on or near the console or front seat

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 belt 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 57 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.

In the following cases, contact your Lexus dealer as soon as
possible:
Any of the SRS side airbags and curtain shield airbags have
been inflated.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
inside (shaded in the illustration) is scratched, cracked, or

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 167.)
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 167.)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 149.)
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.

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.
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.

(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.

On vehicles with side airbags and curtain shield

which the side airbags or curtain shield airbags
deploy even if the child is seated in the child restraint
