GAUGES, METERS AND SERVICE REMINDER INDICATORS
61
(c) Front Passenger's Seat Belt Reminder Light
This light reminds you to buckle up the front passenger's seat
belt.
Once the ignition key is turned to ONº or STARTº, the
reminder light flashes if a passenger sits in the front passenger
seat and does not fasten the seat belt. Unless the front
passenger fastens the belt, the light stays flashing.
If luggage or other load is placed on the front passenger seat,
depending on its weight and how it is placed on the seat,
built-in sensors in the seat cushion may detect the pressure,
causing the reminder light to come on.
(d) SRS Warning Light
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 airbags and front seat belt pretensioners
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.
If either of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle.
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 driver and front
passenger airbags have a problem. If the light flashes, the side
and curtain shield airbags and/or seat belt pretensioners have
a problem.

RSCA OFFº indicator light
The seat belt pretensioners will not operate in a vehicle rollover
if the RSCA OFFº indicator light is on. For details, see Roll
sensing of curtain shield airbags off switchº on page 183.

1Front airbag sensors
2Seat belt pretensioner assemblies
3SRS warning light
4Airbag sensor assembly
The seat belt pretensioner system consists mainly of the above
components, and their locations are shown in the illustration.
The seat belt pretensioners are controlled by the airbag sensor
assembly. The airbag sensor assembly consists of a safing
sensor and airbag sensor.
When the seat belt pretensioners are activated, an operating
noise may be heard and a small amount of non-toxic gas may
be released. This does not indicate that a fire is occurring. This
gas is normally harmless.
Once the seat belt pretensioners have been activated, the seat
belt retractors remain locked.

This indicator comes on when the ignition key is turned to
the ONº position. It goes off after about 6 seconds. This
means the seat belt pretensioners 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 switch 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 either front seat belt does not retract or cannot be pulled
out due to a malfunction or activation of the relevant front
seat belt pretensioner.
The front seat belt pretensioner assembly or surrounding
area has been damaged.

6Front airbag sensors
7Airbag sensor assembly
The SRS front airbag system consists mainly of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensor.The airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers the airbag inflators. At this time a chemical reaction in
the inflators very quickly fills the airbags with non-toxic gas to
help restrain the forward motion of the occupants. The front
airbags then quickly deflate, so that there is no obstruction of
the driver's vision should it be necessary to continue driving.
When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non-toxic gas.
This does not indicate a fire. This smoke may remain inside the
vehicle for some time, and may cause some minor irritation to
the eyes, skin or breathing. Be sure to wash off any residue as
soon as possible to prevent any potential skin irritation with
soap and water. If you safely exit from the vehicle, you should
do so immediately.

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 front 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

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.

SRS SIDE AIRBAGS AND CURTAIN
SHIELD AIRBAGS
The SRS (Supplemental Restraint System) side airbags
and curtain shield airbags are designed to provide further
protection for the driver, front passenger and rear outside
passengers in addition to the primary safety protection
provided by the seat belts.
In response to a severe side impact, the SRS side airbags and
curtain shield airbags work with the seat belts to help reduce
injury by inflating. The SRS side airbags help reduce injuries
mainly to the driver's or front passenger's torso and the SRS
curtain shield airbags help reduce injuries mainly to the
driver's, front passenger's or rear outside passenger's head.Roll sensing function:
In response to a vehicle rollover, the curtain shield airbags on
both sides work with the seat belts to help reduce injury by
inflating. The curtain shield airbags help reduce injuries mainly
to the driver's, front passenger's or second passenger's head
and help prevent them from being thrown out of the vehicle.
(This function can be turned off if inflation is not desired. See
Roll sensing of curtain shield airbags off switchº on page 183.)
The SRS side airbag and curtain shield airbag on the
passenger side are activated even with no passenger in the
front seat or second outside seat.
The curtain shield airbags may activate even when the side
airbags are not activated.
Always wear your seat belt properly.
Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver and front passenger when the SRS side
airbags are inflated.
