SWITCHES
30The automatic light control sensor is on top of the
driver's side instrument panel.
Do not place anything on the instrument panel, and/or do
not affix anything on the windshield to block this sensor.
When the headlights come on, the lights automatically
turn off about 30 seconds after any of the doors is
opened and closed with the ignition key turned to the
ºACCº or ºLOCKº position. To turn them on again, turn
the ignition key to the ºONº position, or turn the headlight
switch off
and then twist the knob until the first or second
clickstop. If you are going to park for over one week,
make sure the headlight switch is off.
When the headlight switch is on with all the doors locked,
pushing the ºLOCKº button on the wireless remote
control transmitter turns off the headlights.
Daytime Running Light System
The headlights turn on at reduced intensity when the
parking brake is released with the engine started, even
with the light switch in the ºOFFº position. They will not
go off until the ignition switch is turned off.
To turn on the other exterior lights and instrument panel
lights, twist the knob to the first clickstop.
Twist the knob to the second clickstop to turn on the
headlights to full intensity for driving at night.
When setting the knob to the third clickstop (ºAUTOº),
the headlights will automatically adjust to full intensity
and/or turn on the other lights depending on the darkness of the surroundings. Likewise, as the
surroundings be
come brighter, the headlights will turn to
reduced intensity, ultimately turning off the other lights.
NOTICE
To prevent the battery from being discharged, do not leave the lights on longer than necessarywhen the engine is not running.

GAUGES, METERS AND SERVICE REMINDER INDICATORS
60If the brake fluid level is correct ...
Have
the warning system checked by your Lexus dealer.
(b) Seat Belt Reminder Light and Buzzer
Once the ignition key is turned to ºONº or ºSTARTº, the
reminder light and buzzer come on if the driver's seat
belt is not fastened. Unless the driver fastens the belt,
the light stays on and the buzzer stops after about 4 to
8 seconds.
(c) SRS Warning Light
The indicator comes on when the ignition key is
turned to the ºACCº or ºONº position. It goes off
after about 6 seconds. This means the SRS is
operating properly.
The SRS warning light system monitors the airbag
sensor assemblies, front airbag sensors, inflators, seat
belt pretensioners, 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.
The light does not come on as described above.
The light stays 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 fail. If the light flashes, the side
airbags and/or seat belt pretensioners fail.

COMFORT ADJUSTMENT
142The driver and front passenger airbags and seat belt
pretensioners are designed to activate in response
to a severe frontal impact within the shaded area
between the arrows in the illustration.
There may be the case that the driver and passenger
airbags
and seat belt pretensioners will not activate with
such an impact in which the occupant wearing the seat
belt correctly would not get serious injury.
The driver and front passenger airbags and seat belt
pretensioners will work if the severity of the impact is
above the designed threshold level, comparable to an
approximate 25 km/h (15 mph) collision when impacting
straight into a fixed barrier that does not move or deform.
If the severity of the impact is below the above threshold
level, the driver and front passenger airbags and seat
belt pretensioners may not work. However, this threshold velocity will be considerably
higher if the vehicle strikes an object, such as a parked
vehicle or sign pole, which can move or deform on
impact, or if it is involved in an underride collision (e.g.
a collision in which the nose of the vehicle ºunderridesº,
or goes under, the bed of a truck, etc.).
It is possible with collision severity at the marginal level
of driver and passenger airbag sensor detection and
activation
that only one of your vehicle's driver and front
passenger airbags and seat belt pretensioners will work.
For the safety of all occupants, be sure to always wear
seat belts.

8Front airbag sensor
The SRS airbag sensor assemblies consist of a safing
sensor and driver and front passenger airbag sensor. In a severe frontal impact, the driver and front passenger
airbag sensor detects deceleration and the system
triggers the front airbag inflators and seat belt
pretensioners. In a severe side impact, the side airbag
sensor
triggers the side airbag inflator. Then a chemical
reaction in the inflators momentarily fills the airbags with
non±toxic gas to help restrain the forward or lateral
motion of the occupants. Then the inflators fill the
airbags and the seat belts are quickly drawn back in by
the retractors to help restrain forward motion of the
occupants.
When the SRS operates, it produces a fairly loud noise
and release some smoke and residue along with
non±toxic gas. This does not indicate a fire. This gas is
normally harmless, however, for those who have
delicate skin, it may cause minor skin irritation. Be sure
to wash off any residue as soon as possible to prevent
minor skin irritation.

Do not use accessories for the seats which
cover the parts where the side airbags should
inflate. Such accessories may prevent the side
airbags from activating correctly, causing
death or serious injury.
Do not modify or remove any wiring. Do not
modify, remove, strike or open any
components, such as the steering wheel pad,
steering wheel, column cover, front passenger
airbag cover, front seats, airbag sensor
assembly or seat belt assemblies. Doing any of
these may cause sudden SRS operation or
disable the system, which could result in death
or serious injury.
Do not modify or replace the seats or surface of
the front seats with side airbags. Such
changes may disable the system or cause the
side airbags to inflate, resulting in death or
serious injury. Consult your Lexus dealer.
Failure to follow these instructions can result in
death or serious injuries.NOTICE
Do not perform any of the following changes without consulting your Lexus dealer. Suchchanges can interfere with proper operation of the
SRS in some cases.
Installation of electronic items such as a mobile two±way radio, cassette tape player orcompact disc player.
Modification of the suspension system.
Modification of the front end structure and sidestructure of the passenger compartment.
Attachment of a grille guard (bull bar, k angaroo
bar, etc.), snow plow, winches or any other equipment to the front end.
Repairs made on or near the front fenders, front
end structure, console, steering column, steering wheel, dashboard near the frontpassenger airbag, front seats or seat belt
assembly.
