D
ODo not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver to lose
control of the vehicle.
ODo not place a cushion between the
driver or passenger and the seatback.
A cushion may prevent correct pos-
ture from being achieved, and reduce
the effectiveness of the seat belt and
head restraint.
ODo not place anything under the front
seats.
Objects placed under the front seats
may become jammed in the seat
tracks and stop the seat from locking
in place. This may lead to an accident
and the adjustment mechanism may
also be damaged.
OAlways observe the legal speed limit
when driving on public roads.
OWhen driving over long distances,
take regular breaks before you start to
feel tired.
Also, if you feel tired or sleepy while
driving, do not force yourself to con-
tinue driving and take a break immedi-
ately.

261-1. For safe use
1To fasten the seat belt, push the
plate into the buckle until a click
sound is heard.
2 To release the seat belt, press the
release button .
QEmergency locking retractor (ELR)
The retractor will lock the belt during a sud-
den stop or on impact. It may also lock if you
lean forward too quickly. A slow, easy motion will allow the belt to extend so that
you can move around fully.
QAutomatic locking retractor (ALR)
When a passenger’s shoulder belt is com-
pletely extended and then retracted even
slightly, the belt is locked in that position
and cannot be extended. This feature is
used to hold a child restraint system (CRS)
firmly. To free the belt again, fully retract the
belt and then pull the belt out once more.
1 Push the seat belt shoulder anchor
down while pressing the release
button .
2 Push the seat belt shoulder anchor
up while pressing the release but-
ton .
Move the height adjuster up and down as
needed until you hear a click.
WARNING
ODo not use the seat belt extender
when installing a child restraint system
because the belt will not securely hold
the child restraint system, increasing
the risk of death or serious injury in the
event of an accident.
OThe personalized extender may not be
safe on another vehicle, when used by
another person, or at a different seat-
ing position other than the one origi-
nally intended.
NOTICE
QWhen using a seat belt extender
When releasing the se at belt, press on
the buckle release button on the
extender, not on the seat belt.

For safety and security
The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a
vehicle rollover.
The pretensioners do not activate in the
event of a minor frontal impact, a minor
side impact or a rear impact.
QReplacing the belt after the preten-
sioner has been activated
If the vehicle is involved in multiple colli-
sions, the pretensioner will activate for the
first collision, but will not activate for the
second or subsequent collisions.
Seat belt pretensioners (front
and outboard rear seats)
WARNING
QSeat belt pretensioners
Observe the following precautions to
reduce the risk of in jury in the event of
sudden braking, sudd en swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
ODo not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result, the seat belt pre-
tensioner for the front passenger’s seat
may not activate in the event of a colli-
sion.
OIf the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.

Your vehicle is equipped with ADVANCED AIRBAGS designed based on the
US motor vehicle safety standards (FMVSS208). The airbag sensor assembly
(ECU) controls airbag deployment based on information obtained from the sen-
sors etc. shown in the system components diagram above. This information
includes crash severity and occupant information. As the airbags deploy, a chemi-
cal reaction in the inflators quickly fills the airbags with non-toxic gas to help
restrain the motion of the occupants.
QIf the SRS airbags deploy (inflate)
OSlight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
OA loud noise and white powder will be
emitted.
OParts of the airbag module (steering
wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front
and rear pillars, and roof side rails, may
be hot for several minutes. The airbag
itself may also be hot.
OThe windshield may crack.
OThe hybrid system will be stopped and
fuel supply to the engine will be stopped.
(  P.65)
OAll of the doors will be unlocked.
( P.105)
OThe brakes and stop lights will be con-
trolled automatically. ( P.253)
OThe interior lights will turn on automati-
cally. ( P.283)
OThe emergency flashers will turn on auto-
matically. ( P.358)
OFor Lexus Enform Safety Connect sub-
scribers, if any of the following situations
occur, the system is designed to send an
emergency call to the response center,
notifying them of the vehicle’s location (without needing to push the “SOS” but-
ton) and an agent will attempt to speak
with the occupants to ascertain the level
of emergency and assistance required. If
the occupants are unable to communi-
cate, the agent automatically treats the
call as an emergency and helps to dis-
patch the necessary emergency services.

•An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear- end collision.
QSRS airbag deployment conditions (SRS
front airbags)
OThe SRS front airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to an approximately 12 - 18
mph [20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform).
However, this threshold velocity will be
considerably higher in the following situ-
ations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can
move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes
under, the bed of a truck
