For safety and security
Adjust the angle of the seatback so
that you are sitting straight up and
so that you do not have to lean for-
ward to steer. (P.102)
Adjust the seat so that you can
depress the pedals fully and so that
your arms bend slightly at the
elbow when gripping the steering
wheel. ( P.102)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
(  P.107)
Wear the seat belt correctly.
(  P.24) Make sure that all occupants are wear-
ing their seat belts before driving the
vehicle. (
P.24)
Use a child restraint system appropri-
ate for the child until the child becomes
large enough to properly wear the
vehicle’s seat belt. ( P.41)
Make sure that you can see backward
clearly by adjusting the inside and out-
side rear view mirrors properly.
(  P.110, 112)
For safe driving
For safe driving, adjust the seat and
mirror to an appropriate position
before driving.
Correct driving posture
WARNING
■For safe driving
Observe the following precautions.
Failure to do so may result in death or
serious injury.
A
B
C
D
●Do not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver to lose
control of the vehicle.
●Do 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.
●Do 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.
●Always observe the legal speed limit
when driving on public roads.
●When 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.
Correct use of the seat belts

241-1. For safe use
Seat belts
Make sure that all occupants are
wearing their seat belts before driv-
ing the vehicle.
WARNING
Observe the following precautions to
reduce the risk of injury in the event of
sudden braking, sudden swerving or an
accident.
Failure to do so may cause death or seri-
ous injury.
■Wearing a seat belt
●Ensure that all passengers wear a seat
belt.
●Always wear a seat belt properly.
●Each seat belt should be used by one
person only. Do not use a seat belt for
more than one person at once, includ-
ing children.
●Lexus recommends that children be
seated in the rear seat and always use
a seat belt and/or an appropriate child
restraint system.
●To achieve a proper seating position,
do not recline the seat more than nec-
essary. The seat belt is most effective
when the occupants are sitting up
straight and well back in the seats.
●Do not wear the shoulder belt under
your arm.
●Always wear your seat belt low and
snug across your hips.
■Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. (
P.25)
Women who are pregnant should posi-
tion the lap belt as low as possible over
the hips in the same manner as other
occupants, extending the shoulder belt
completely over the shoulder and avoid-
ing belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a colli-
sion.
■People suffering illness
Obtain medical advice and wear the seat
belt in the proper way. (
P.25)
■When children are in the vehicle
P.48
■Seat belt damage and wear
●Do not damage the seat belts by allow-
ing the belt, plate, or buckle to be
jammed in the door.
●Inspect the seat belt system periodi-
cally. Check for cuts, fraying, and loose
parts. Do not use a damaged seat belt
until it is replaced. Damaged seat belts
cannot protect an occupant from
death or serious injury.

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 .
■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 lock ed 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. ( P.41)
■After the rear center seat belt has been
used
Stow the buckle as shown.
1 Push the seat belt shoulder anchor
down while pressing the release
button .
2 Push the seat belt shoulder anchor
up.
Move the height adjuster up and down as
needed until you hear a click.
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.

Adjusting the seat belt shoulder
anchor height (front seats)
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
pretensioner 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.
■PCS-linked seat belt pretensioner con-
trol
If the PCS (Pre-Collision System) deter-
mines that the possibility of a collision with a
vehicle is high, the seat belt pretensioners
will be prepared to operate.
Seat belt pretensioners (front
seats and outboard rear seats)WARNING
■Seat belt pretensioners
●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
pretensioner for the front passenger’s
seat may not activate in the event of a
collision.
●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.

301-1. For safe use
Your vehicle is equipped with ADVANCED AIRBAGS designed based on the US
motor vehicle safety standards (FMVSS20 8). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtain ed from the sensors etc.
shown in the system components diagram above. This information includes crash
severity and occupant information. As th e airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with no n-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 seats, parts of the front and
rear pillars, an d roof side rails may be hot
for several minutes. The airbag itself may
also be hot.
●The windshield may crack.
●All of the doors will be unlocked. ( P.91)
●The brakes and stop lights will be con-
trolled automatically. (P.230)
●The interior lights will turn on automati-
cally. (P.254)
●The emergency flashers will turn on auto-
matically. ( P.320)
●Fuel supply to the engine will be stopped.
(P.328)
●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 assi stance 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.54)
• 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 threshol d velocity will be
considerably higher in the following situa-
tions:
• 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 “u nderrides”, or goes
under, the bed of a truck
●Depending on the type of collision, it is
possible that only the seat belt
pretensioners 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 front 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 event of an impact that
exceeds the set threshold 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-
