■Child seat belt usage
The seat belts of your vehicle were princi-
pally designed for persons of adult size.
●Use a child restraint system appropriate
for the child, until the child becomes large
enough to properly wear the vehicle’s
seat belt. ( P.43)
●When the child becomes large enough to
properly wear the vehicle’s seat belt, fol-
low the instructions regarding seat belt
usage. ( P.24)
■Seat belt extender
If your seat belts cannot be fastened
securely because they are not long enough,
a personalized seat be lt extender is avail-
able from your Lexus dealer free of charge.
■Rear seat belt
Use the seat belt after passing it through the
guide if the seat belt comes free from the
guide.
WARNING
●Ensure that the belt and plate are
locked and the belt is not twisted.
If the seat belt do es not function cor-
rectly, immediately contact your Lexus
dealer.
●Replace the seat a ssembly, including
the belts, if your vehicle has been
involved in a serious accident, even if
there is no obvious damage.
●Do not attempt to install, remove,
modify, disassemble or dispose of the
seat belts. Have an y necessary repairs
carried out by your Lexus dealer. Inap-
propriate handling may lead to incor-
rect operation.
Correct use of the seat belts
WARNING
■Using a seat belt extender
Observe the following precautions to
reduce the risk of in jury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
●Do not wear the seat belt extender if
you can fasten the seat belt without the
extender.

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 .
■Emergency 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.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is com-
pletely extended and then retracted even
slightly, the belt is lo cked 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
●Do 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.
●The 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
■When 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.
This helps prevent damage to the vehicle
interior and the extender itself.

WARNING
■Adjustable shoulder anchor
Always make sure the shoulder belt is
positioned across the center of your
shoulder. The belt should be kept away
from your neck, but not falling off your
shoulder. Failure to do so could reduce
the amount of protection in an accident
and cause death or serious injuries in the
event of a sudden stop, sudden swerve
or accident.

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.
■Replacing the belt after the preten-
sioner has been activated
If the vehicle is involv ed 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
■Seat belt pretensioners
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking, sudd en swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
●Do 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.
●If 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 ADVA NCED 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 compon ents diagram above. This information
includes crash severity and occupant info rmation. 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.
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
●A loud noise and white powder will be
emitted.
●Parts of the airbag module (steering
wheel hub, airbag cover and inflator) as
well as the front seat s, parts of the front
and rear pillars, and r oof side rails may be
hot for several minutes. The airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped and
fuel supply to the engine will be stopped.
(  P.67)
●All of the doors will be unlocked.

●The brakes and stop lights will be con-
trolled automatically. ( P.248)
●The interior lights will turn on automati-
cally. ( P.278)
●The emergency flashers will turn on auto-
matically. ( P.358)
●For 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.
(
 P.55)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear- end collision.
■SRS airbag deployment conditions (SRS
front airbags)
●The 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
●Depending on the type of collision, it is

possible that only the seat belt preten-
sioners will activate.
●The SRS front airbags for the front pas-
senger will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the SRS fr ont airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied.
■SRS airbag deployment conditions (SRS
side and curtain shield airbags)
●The SRS side and curtain shield airbags
will deploy in the even t of an impact that
exceeds the set thresh old level (the level
of force corresponding to the impact
force produced by an approximately
3300 lb. [1500 kg] vehicle colliding with
the vehicle cabin from a direction per-
pendicular to the vehi cle orientation at an
approximate speed of 12 - 18 mph [20 -
30 km/h]).
●Both SRS curtain shield airbags may
deploy in the event of a severe side colli-
sion.
●Both SRS curtain shield airbags will
deploy in the event of vehicle rollover.
●Both SRS curtain shield airbags may also
deploy in the event of a severe frontal
collision.
■Conditions under which the SRS air-
bags may deploy (inf late), other than a
collision
The SRS front airbags and SRS curtain
shield airbags may also deploy if a serious
impact occurs to the underside of your
vehicle. Some examples are shown in the
illustration.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling The SRS curtain shield
airbags may also
deploy under the situations shown in the
illustration.
●The angle of vehicle tip-up is marginal.
●The vehicle skids and hits a curb stone.
■Types of collisions that may not deploy
the SRS airbags (SRS front airbags)
The SRS front airbags do not generally
inflate if the vehicle is involved in a side or
rear collision, if it rolls over, or if it is involved
in a low-speed frontal collision. But, when-
ever a collision of any type causes sufficient
forward deceleration of the vehicle, deploy-
ment of the SRS fron t airbags may occur.
●Collision from the side
●Collision from the rear
●Vehicle rollover
■Types of collisions that may not deploy
the SRS airbags (SRS side and curtain
shield airbags)
The SRS side and curtain shield airbags
may not activate if the vehicle is subjected
to a collision from the side at certain angles,

●The portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the SRS curtain shield airbags
inside is scratched, cracked, or otherwise
damaged.
WARNING
■SRS airbag precautions
Observe the following precautions
regarding the SRS airbags.
Failure to do so may cause death or seri-
ous injury.
●The driver and all passengers in the
vehicle must wear their seat belts
properly.
The SRS airbags are supplemental
devices to be used with the seat belts.
●The SRS driver airbag deploys with
considerable force, and can cause
death or serious injury especially if the
driver is very close to the airbag. The
National Highway Traffic Safety
Administration (NHTSA) advises:
Since the risk zone for the driver’s air-
bag is the first 2 - 3 in. (50 - 75 mm) of
inflation, placing yourself 10 in. (250
mm) from your driver airbag provides
you with a clear margin of safety. This
distance is measured from the center
of the steering wheel to your breast-
bone. If you sit less than 10 in. (250
mm) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals
comfortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many
drivers can achieve the 10 in. (250
mm) distance, even with the driver
seat all the way forward, simply by
reclining the back of the seat some-
what. If reclining the back of your seat
makes it hard to see the road, raise
yourself by using a firm, non-slippery
cushion, or raise the seat if your vehi-
cle has that feature.
• If your steering wheel is adjustable, tilt it downward. This points the airbag
toward your chest instead of your
head and neck.
The seat should be adjusted as recom-
mended by NHTSA above, while still
maintaining control of the foot pedals,
steering wheel, and your view of the
instrument panel controls.

341-1. For safe use
WARNING
●If the seat belt extender has been con-
nected to the driver’s seat belt buckle
but the seat belt extender has not also
been fastened to the latch plate of the
driver’s seat belt, the SRS front airbags
for the driver will judge that the driver
is wearing the seat belt even though
the seat belt has not been connected.
In this case, the SRS front airbags for
the driver may not activate correctly in
a collision, resulting in death or serious
injury in the event of a collision. Be
sure to wear the seat belt with the seat
belt extender.
●The SRS front passenger airbag also
deploys with considerable force, and
can cause death or serious injury
especially if the front passenger is very
close to the airbag. The front passen-
ger seat should be as far from the air-
bag as possible with the seatback
adjusted, so the front passenger sits
upright.
●Improperly seated and/or restrained
infants and children can be killed or
seriously injured by a deploying air-
bag. An infant or child who is too small
to use a seat belt should be properly
secured using a child restraint system.
Lexus strongly recommends that all
infants and children be placed in the
rear seats of the vehicle and properly
restrained. The rear seats are safer for
infants and children than the front pas-
senger seat. ( P.43)
●Do not sit on the edge of the seat or
lean against the dashboard.
●Do not allow a child to stand in front of
the SRS front passenger airbag unit or
sit on the knees of a front passenger.
●Do not allow the front seat occupants
to hold items on their knees.
●Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
●Do not allow anyone to kneel on the
passenger seats toward the door or
put their head or hands outside the
vehicle.
