COMFORT ADJUSTMENT
128Adjust the mirror so that you can just see the side of
your vehicle in the mirror.
When the inside rear view mirror darkens in ºAUTOº
mode, the outside rear view mirrors also darken to
reduce the reflection of the headlights of the following
vehicle. For details, see ºInside rear view mirrorº on
page 131.
When you push the rear window defogger switch, the
heater panels in the outside rear view mirrors will quickly
clear the mirror surface.
CAUTION
Do not adjust the mirror while the vehicle is moving.
It may cause the driver to mishandle the vehicle and
an accident may occur, resulting in personal injuries.
Since the mirror surfaces can get hot, keep your
hands off them when the rear window and outside
rear view mirror defogger switch is on.

COMFORT ADJUSTMENT
132Adjust the mirror so that you can just see the rear of
your vehicle in the mirror.
Pushing the switch changes the mode between
ºAUTOº and ºDAYº.
The indicator comes on when the ºAUTOº mode is
selected.
ºDAYº mode: The mirror surface is normal.
ºAUTOº mode: If the mirror detects light from the
headlights of the vehicle behind you, the mirror
surface darkens slightly to reduce the reflected
light.
When the inside rear view mirror surface changes, the
outside rear view mirror surfaces will also become
darker.
When the ignition key is inserted and turned on, the
inside rear view mirror always turns on in the ºAUTOº
mode.When the outside air temperature is low, it may take a
little longer for the mirror to darken in response to the
detection of headlights.
CAUTION
Do not adjust the mirror while the vehicle is moving. It
may cause the driver to mishandle the vehicle and an
accident may occur resulting in personal injuries.

COMFORT ADJUSTMENT
136The retractor will lock the belt during a sudden stop or on
impact. It also may lock if you lean forward too quickly.
A slow, easy motion will allow the belt to extend, and you
can move around freely.
When a passenger's shoulder belt is completely
extended and is then retracted even slightly, the belt is
locked in that position and cannot be extended. This
feature is used to hold the child restraint system
securely. (For details, see ºChild restraintº on page 173.)
To free the belt again, fully retract the belt and then pull
the belt out once more.
If the seat belt cannot be pulled out of the retractor, firmly
pull the belt and release it. You will then be able to
smoothly pull the belt out of the retractor.

This indicator comes on when the ignition key is
turned to the ªACCº or ªONº position. It goes off
after about 6 seconds. This means the front seat
belt pretensioners are operating properly.
This warning light system monitors the airbag sensor
assembly, side airbag sensor assemblies, front airbag
sensors, inflators, seat belt pretensioner assembly,
warning light, interconnecting wiring and power sources.

1Front airbag sensor
2Seat belt pretensioner assembly
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 pretensioner is controlled by the airbag
sensor assembly. The airbag sensor assembly consists
of a safing sensor and airbag sensor.
When a seat belt pretensioner is 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 seat belt pretensioner has been activated, the
seat belt retractor remains locked.

This front seat belt pretensioner system has a service
reminder indicator to inform the driver of operating
problems. If any of the following conditions occurs, this
indicates a malfunction of the pretensioners. Contact
your Lexus dealer as soon as possible to service the
vehicle.
When the ignition key is turned to the ªACCº or ªONº
position, the light does not come on or flashes.
The light flashes while driving.
If either front seat belt does not retract or cannot be
pulled out due to a malfunction or activation of the
pretensioner.
The front seat belt pretensioner assembly or
surrounding area has been damaged.The front parts of the vehicle (shaded in the
illustration) were involved in an accident that did not
cause the seat belt pretensioners to operate.
The front seat belt pretensioner assembly is
scratched, cracked, or otherwise damaged.

153 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 airbags
are operating properly.
The SRS warning light system monitors the airbag
sensor assembly, front airbag sensors, inflators,
warning light, interconnecting wiring and power sources.

(airbag and inflator)

7Front airbag sensors
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 sensors.
In a severe frontal impact, the driver and front passenger
airbag sensors detect deceleration and the system
triggers the front airbag inflators. In a severe side
impact, the side airbag sensor triggers the side airbag
inflator. Then a chemical reaction in the inflators quickly
fills the airbags with non±toxic gas to help restrain the
forward or lateral 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 a minor skin irritation. Be
sure to wash off any residue as soon as possible to
prevent any potential skin irritation.
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, it may also cause minor burns or abrasions and
swelling.
Parts of the airbag module (steering wheel hub,
dashboard, front seats) may be hot for several minutes,
but the airbags themselves will not be hot. The airbags
are designed to inflate only once.
A crash severe enough to inflate the driver and front
passenger airbags may break the windshield as the
vehicle buckles. In vehicles with a front passenger
airbag, the windshield may also be damaged by
absorbing some of the force of the inflating airbag.
