NOTICE
To prevent the battery from being discharged, do not
leave the lights on longer than necessary when the
engine is not running.
Automatic headlight leveling system (vehicles
with discharge headlight only)
Vehicle position changes according to loading condition,
passengers getting on and off, vehicle acceleration and
deceleration, etc. However, as the headlight beam level is
always maintained automatically by the system at the proper
level, your headlights do not dazzle other road users.
If this system fails, the warning light in the instrument cluster
comes on. If this occurs, have your vehicle checked by your
Lexus dealer.If you replace the rear suspension and/or the vehicle height
changes, contact your Lexus dealer to check the automatic
headlight leveling system and headlight beam level.

vehicle stability control system or traction control system.
The light will come on when the ignition key is turned to ONº
and will go off after a few seconds.
If the light comes on while driving, the system does not work.
However, as conventional braking operates when applied,
there is no problem to continue your driving.
In the following cases, contact your Lexus dealer:
The warning light does not come on after the ignition key is
turned to ONº.
The warning light remains on after the ignition key is turned
to ONº.
The warning light comes on while driving.
The TRAC OFFº indicator light will come on when the VSCº
warning light comes on even if the TRAC OFFº switch is not
pushed.

in the automatic headlight leveling system.
If it comes on, have your vehicle checked by your Lexus dealer.
(p) Low Fuel Level Warning Light
This light comes on when the fuel level in the tank becomes
nearly empty. Fill the tank as soon as possible.
On inclines or curves, due to the movement of fuel in the tank,
the low fuel level warning light may come on earlier than usual.

driver's door with the ignition key in the ACCº or LOCKº
position.

OCCUPANT RESTRAINT SYSTEM

1Front passenger occupant classification system
(ECU and sensors)
2Airbag module for front passenger
(airbag and inflator)
3SRS warning light
4Airbag module for driver (airbag and inflator)
5Driver's seat position sensor
6Driver's seat belt buckle switch
7Front passenger's seat belt buckle switch
8AIRBAG OFFº and AIRBAG ONº indicator lights
9Front airbag sensors
10Airbag 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 front 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.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant's hands, arms, chest or head are in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to: avoid placing any
object or part of the body between the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.

7Front passenger's seat belt buckle switch
8AIRBAG OFFº and AIRBAG ONº indicator lights
9Airbag sensor assembly
The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are shown
in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensor.
In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
At this time a chemical reaction in the inflators quickly fills the
airbags with non-toxic gas to help restrain the lateral motion
of the occupants.

OCCUPANT RESTRAINT SYSTEM
153 To ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not occur.
Make sure the AIRBAG ONº indicator light is illuminated when
an adult is seated in the front passenger seat. If the AIRBAG
OFFº indicator light is illuminated, ask the passenger to sit up
straight, well back in the seat, and with the seat belt worn
correctly. If the AIRBAG OFFº indicator light still remains
illuminated, either ask the passenger to move to the rear seat,
or if that is not possible, move the front passenger seat fully
rearward.
The AIRBAG OFFº and AIRBAG ONº indicator lights will
be initially illuminated when the ignition switch is turned
to the ONº position. It will remain for about four seconds
and then go off. After the two seconds, the front
passenger occupant classification system operates and
judges which indicator light to turn on.
The SRS warning light and AIRBAG OFFº indicator light
will be illuminated if there is a malfunction in the front
passenger occupant classification system.

*1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may
recognize him/her as a child depending on his/her physique and posture.
*
2: When a larger child who has outgrown a child restraint system sits in the front passenger seat, the system may recognize him/her
as an adult depending on his/her physique or posture.
*
3: Never install a rear-facing child restraint system on the front passenger seat. A forward-facing child restraint system should
only be installed on the front passenger seat when it is unavoidable. (See Child restraint systemº on page 158 as for installing
the child restraint system.)
*
4: In the event the front passenger does not wear a seat belt.
