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.99)
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.99)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
( P.105)
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.40)
Make sure that you can see backward
clearly by adjusting the inside and out-
side rear view mirrors properly.
( P.109, 110)
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.

Extend the shoulder belt so that it
comes fully over the shoulder, but
does not come into contact with the
neck or slide off the shoulder.
 Position the lap belt as low as possi-
ble over the hips.
 Adjust the position of the seatback.
Sit up straight and well back in the
seat. 
Do not twist the seat belt.

Twisted
■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.40)
●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.
WARNING
●Inspect the seat be lt 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.
●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

you can fasten the seat belt without the
extender.

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, fu lly retract the belt and
then pull the belt out once more. ( P.40)
When fastening a front seat belt,
ensure that it is passed through the seat
belt guide. Passing the seat belt
through the guide enables the seat belt
to be easily extended.
When you get into or ou t of the rear seats,
release the seat belt from the seat belt
guide.
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
■When using the seat belt guide
●Always make sure that the belt is not
twisted, and runs freely through the
guide.
●Regardless of whether the guide is
used or not, always secure the seat belt
guide button.
●Do not hang from or pull the guide
forcefully.

301-1. For safe use
severity and occupant information. As the airbags deploy, a chemical 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 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.89)
●Fuel supply to the engine will be stopped.
( P.294)
●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.52)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a sever 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 “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 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-
pendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 -
30 km/h]).
●Both SRS curtain shield airbags will
deploy in the event of vehicle rollover.
●All SRS side and curtain shield airbags
will deploy in the event of a severe frontal
collision.
■Conditions under which the SRS air-
bags may deploy (inflate), other than a
collision
The SRS front airbags and SRS side and
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
