Auto tilt away*
16L012-2
When the ignition key is removed, the steering column moves
forward away from the driver and also tilts up for easy exit and
entry.
When the key is inserted in the ignition switch, the steering column
returns to the previously set position.
NOTE: *This feature can be set inoperative. Ask your Lexus
dealer for details.
OUTSIDE REAR VIEW MIRRORS
16L016
Adjust the mirror so you can just see the side of your vehicle in
the mirror.
When the inside rear view mirror darkens in ”AUTO” mode, the
outside rear view mirrors also darken to reduce the reflection of the
headlights of the following vehicle. For details, see ”Inside rear view
mirror” on page 79.
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.

Folding rear view mirrors
16L018
To fold the rear view mirror, push backward.
The rear view mirrors can be folded backward for parking in
restricted areas.
CAUTION
Do not drive with the mirrors folded backward. Both the
driver and passenger side rear view mirrors must be extended
and properly adjusted before driving.
INSIDE REAR VIEW MIRROR
16L019-1
Pushing the switch changes the mode between ”AUTO” and
”DAY”.
The indicator comes on when the ”AUTO” mode is selected.
”DAY” mode: The mirror surface is normal.
”AUTO” 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 ”AUTO” mode.
Adjust it before driving so that the rear view is the best.
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.

81 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.
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.
Front seat belt buckle illumination
16L020
Opening the driver’s door lights up the driver’s seat belt buckle
for easy use. The same applies for the front passenger’s door and
seat belt buckle.
The light remains on for 15 seconds after the door is closed, but goes
off immediately when all doors are locked.
Fastening front and rear seat belts
16L115-1
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.

COMFORT ADJUSTMENT
82When 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 ”Child restraint” on page 98.) 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.
16L116-1
Adjust the position of the lap and shoulder belts.
1
Position the lap belt as low as possible on your hips not on
your waist.
2
Adjust it to a snug fit by pulling the shoulder portion upward
through the latch plate.
CAUTION
Highpositioned lap belts and loosefitting belts both could
cause severe injuries due to sliding under the lap belt
during a collision or other unintended result. Keep the lap
belt positioned as low on hip as possible.
For your safety, do not place the shoulder belt under your
arm.

Side airbags
Side airbags:
In response to a severe side impact, the side airbag for the driver
or front passenger works together with the seat belt to help
preventing or reducing injury by inflating, in order to decrease
the impact mainly on the driver or front passenger’s chest.
The side airbag on the passenger seat is activated even with no
passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
SRS side airbags inflate with considerable force. To avoid
potential death or serious injury during inflation of a side
airbag, Lexus strongly recommends that the driver and front
passenger;
Wear their seat belt.
Remain properly seated with their back against the seat at
all times.
16L136-2
The indicator comes on when the ignition key is turned to the
”ACC” or ”ON” 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, inflators, seat belt pretensioners, warning light,
interconnecting wiring and power sources.

The side airbags are not designed to inflate if the vehicle is rolled
over.
If the impact on the body of the passenger compartment is not strong
as illustrated above, the relevant side airbag may not inflate.

Driver and front passenger airbag sensor assembly
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 nontoxic
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

conventionally. Contact your Lexus dealer as soon as possible to
service the vehicle.
