your arms bend slightly at the
elbow when gripping the steering
wheel. ( P.121)

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.

261-1. 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.
●RX350L: Do not let third-row seat
passengers to use second-row seat
seat belts.
■Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. (
P.27)
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.27)
■When children are in the vehicle

For safety and security
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.
■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.45)
●When the child becomes large enough to
properly wear the vehicle’s seat belt, fol-
low the instructions regarding seat belt
usage. ( P.26)
■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
■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 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
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.

281-1. 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 the child restraint system (CRS) firmly.
To free the belt again, fully retract the belt
and then pull the belt out once more.
(  P.45)
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.

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.

WARNING
●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 airbag.
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.45)
●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.
●Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the instrument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy.

WARNING
●Do not put weight on the front passen-
ger seat by putting your hands or feet
on the front passenger seat seatback
from the rear passenger seat.
●Do not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.
●Do not put objects under the front pas-
senger seat.
●Do not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “AIR BAG
OFF” indicator light to be illuminated,
which indicates that the SRS airbags
for the front passenger will not activate
in the event of a severe accident. If the
seatback touches the rear seat, return
the seatback to a position where it
does not touch the rear seat. Keep the
front passenger seatback as upright as
possible when the vehicle is moving.
Reclining the seatback excessively
may lessen the effectiveness of the
seat belt system.
●If an adult sits in the front passenger
seat, the “AIR BAG ON” indicator light
is illuminated. If the “AIR BAG OFF”
indicator is illumin ated, ask the passen-
ger to sit up straight, well back in the
seat, feet on the floor, and with the seat
belt worn correctly. If the “AIR BAG
OFF” indicator still remains illumi-
nated, either ask the passenger to
move to the rear seat, or if that is not
possible, move the front passenger
seat fully rearward.
●When it is unavoidable to install a for-
ward-facing child restraint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
(
P.46)
●Do not modify or remove the front
seats.
●Do not kick the front passenger seat or
subject it to severe impact. Otherwise,
the SRS warning light may come on to
indicate a malfunction of the front pas-
senger occupant clas sification system.
In this case, contact your Lexus dealer
immediately.
●Child restraint systems installed on the
rear seat should not contact the front
seatbacks.
●Do not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.
●Do not modify or replace the uphol-
stery of the front seat.

■Unoccupied
■There is a malfunction in the system
*1: The system judges a person of adult size as an adult. When a smaller adult sits in the
front passenger seat, the system may not re cognize him/her as an adult depending on
his/her physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in se at, child in booster seat or child in convertible seat, the sys-
tem may not recognize him/her as a child. Factors which may affect this can be the phy-
sique or posture.
*5: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint system should only be installed on the front passenger seat
when it is unavoidable. ( P.45)
*6: In case the indicator light is not illuminated, consult this manual on how to install the child
restraint system properly. ( P.46)
