(c) Front Passenger’s Seat Belt ReminderLight
This light reminds you to buckle up the front passenger’s seat
belt.
Once the ignition key is turned to “ON” or “START”, 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 “ON” 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,
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 “ON” 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.

The front seat belt pretensioner system consists mainly of the
above components, and their locations are shown in the
illustration.
The front seat belt pretensioners are controlled by the airbag
sensor assembly. The airbag sensor assembly consists of a
safing sensor and airbag sensor.
When the front seat belt pretensioners are activated, an
operating noise may be heard and a small amount of
smoke−like gas may be released. This gas is harmless and
does not indicate that a fire is occurring.
Once the front seat belt pretensioners have been activated, the
seat belt retractors remain locked.

CAUTION
The SRS curtain shield airbags inflate with considerable
force. To avoid potential death or serious injury when
they inflate, the driver, front passenger and second
outside passengers must:
Wear their seat belts properly.
 Remain properly seated with their back upright and
against the seat at all times.
The indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS 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,
interconnecting wiring and power sources. (For details, see
“Service reminder indicators and warning buzzers” on page 43
for instructions.)
The SRS front airbags are designed to deploy in severe
(usually frontal) collisions where the magnitude and
duration of the forward deceleration of the vehicle
exceeds the designed threshold level.

The SRS 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. In an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers the airbag inflators. In a severe side impact, the side
and curtain shield airbag sensor and/or the curtain shield
airbag sensor trigger(s) the si
de and curtain shield airbag
inflators and/or the curtain shield airbag inflator. At this time a
chemical reaction in the inflators very quickly fills the airbags
with non −toxic gas to help restrain the forward or lateral 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 can physically and safely exit the vehicle
after a collision, you should do so at the first opportunity.

Automatic notifications
If an airbag deploys, an emergency signal is sent
automatically to the Lexus Link Call Center. In your vehicle, the
system announces “Placing an emergency call to the Lexus
Link Center.” In response to the signal, Lexus Link Advisor will
attempt to communicate with you first. If the Advisor cannot get
any response from you, the Advisor will locate your vehicle
through the GPS, call the nearest emergency services
provider, describe the situation and your location. If necessary,
the Advisor will transfer your call to the emergency services
operator.
If the theft deterrent system on your vehicle is activated,
the Lexus Link System on your vehicle will automatically call
the Lexus Link Call Center. The Advisor will attempt to contact
you to determine whether the alarm is valid.
If you report to the Lexus Link Call Center that your vehicle has
been stolen, the Advisor will locate, track and provide location
information to the appropriate law enforcement authority. To
protect subscriber privacy, the Lexus Link Call Center will not
provide the location of a vehicle to anyone other than a law
enforcement authority.
If you accidentally activate the vehicle alarm, push the
“UNLOCK” button on the wireless remote control key within 55
seconds after the alarm was set off, or insert the key into the
door keyhole or ignition switch. The Lexus Link System will
cancel the theft call.NOTICE
 Once the emergency button is pushed, an emergency
call cannot be cancelled.
 This system is only operational in GPS and analog
cellular coverage areas. Upon subscription
expiration, all Lexus Link services (i.e. automatic
notification, emergency call functions, service call
functions, door locking/unlocking function) are
deactivated.

FUEL PUMP SHUT OFF SYSTEM
The fuel pump shut off system stops supplying fuel to the
engine to minimize the risk of fuel leakage when the engine
stalls or an airbag inflates upon collision. To restart the engine
after the fuel pump shut off system activates, turn the ignition
switch to “ACC” or “LOCK” once and start it.
CAUTION
Inspect the ground under the vehicle before restarting
the engine. If you find that liquid has leaked onto the
ground, it is the fuel system that has been damaged and
it is in need of repair. In this case, do not restart the
engine.
