SV16064
To change the steering wheel angle, hold the steering
wheel, pull the lock release lever toward you, tilt the
steering wheel to the desired angle and release the lever.
When the steering wheel is in a low position, it will spring up as
you release the lock release lever.
CAUTION
 Do not adjust the steering wheel while the vehicle is
moving. It may cause the driver to mishandle the
vehicle and an accident may occur resulting in death
or injuries.
 After adjusting the steering wheel, try moving it up

OUTSIDE REAR VIEW MIRRORS
SV16010
Adjust the mirror so that you can just see the side of your
vehicle in the mirror.
Be careful when judging the size or distance of any object seen
in the outside rear view mirror on the passenger's side. It is a
convex mirror with a curved surface. Any object seen in a
convex mirror will look smaller and farther away than if seen in
a normal flat mirror.
When you push the rear window and outside rear view mirror
defogger switch or operate the wipers, the heater panels in the
outside rear view mirrors will quickly clear the mirror surface.
(See º Rear window and outside rear view mirror defogger, and
windshield wiper deicer switchº on page 32.)
Some models: 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 104.

When driving at night, pull the lever toward you to reduce
the glare from the headlights of vehicles behind you.
Before adjusting the mirror to the position with most clarity,
push the day±night change lever forward (daylight driving
position).
Remember that by reducing glare you also lose some rear view
clarity.
CAUTION
Do not adjust the mirror while the vehicle is moving.
Doing so may cause the driver to mishandle the vehicle
and an accident may occur resulting in personal death
or injuries.
SV16128

Type B
Adjust the m irror 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.

Keep the belts clean and dry. If they need cleaning,
use a mild soap solution or lukewarm water. Never
use bleach, dye, or abrasive cleaners ± they may
severely weaken the belts. (See ºCleaning the
interiorº on page 357 for instructions.)
 Replace the belt assembly (including bolts) if it has
been used in a severe impact. The entire assembly
should be replaced even if damage is not obvious.
Fastening front and rear seat belts
SV16013
Adjust the seat as needed and sit up straight and well back
in the seat. To fasten your belt, pull it out of the retractor
and insert the tab into the buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size and the
seat position. The 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 135.) 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.
CAUTION
 After inserting the tab, make sure the tab and buckle
are locked and that the belt is not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
 If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed. It cannot protect
an adult occupant or your child from injury.

Front seat belt pretensioners
SV16151
The driver and front passenger's seat belt pretensioners
are designed to be activated in response to a severe
frontal impact.
When the airbag sensor detects the shock of a severe frontal
impact, the front seat belts are quickly drawn back by the
retractor so that the belts snugly restrain the front seat
occupants.
The front seat belt pretensioners are activated even with no
passenger in the front seat.
Collisions occurring at certain speeds and angles may cause
the seat belt pretensioners and SRS airbags not to operate all
together.
SV16061
This 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 front seat belt pretensioners are
operating properly.
The warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensors, front seat belt pretensioner assemblies, inflators,
warning light, interconnecting wiring and power sources. (For
details, see ºService reminder indicators and warning buzzersº
on page 42.)

4Front airbag sensors
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
Do not modify, remove, strike or open the front seat belt
pretensioner assemblies, airbag sensor or surrounding
area or wiring. Doing any of these may cause sudden
operation of the front seat belt pretensioners or disable
the system, which could result in death or serious
injury.
Failure to follow these instruction can result in death or
serious injury.

SV16061
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 airbags or pretensioners. Contact your
Lexus dealer as soon as possible to service the vehicle.
 The light does not come on when the ignition key is turned
to the ºACCº or ºONº position, or remains on.
 The light comes on or flashes while driving.

COMFORT ADJUSTMENT
124The SRS warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensors, front seat belt pretensioner assemblies, inflators,
warning light, interconnecting wiring and power sources. (For
details,
see ºService reminder indicators and warning buzzersº
on page 42.)
SS16042
The SRS front airbag system is designed to activate in
response to a severe frontal impact within the shaded area
between the arrows in the illustration.
The SRS front airbags 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 SRS front airbags 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 that in some collisions at the lower zone of airbag
sensor
detection and activation, the SRS airbags and seat belt
pretensioners will not operate all together.
For the safety of all occupants, always wear your seat belts
properly.
