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.

LS500h_OM_OM50F42U_(U) Seat belts Make sure that all occupants are
wearing their seat belts before driv-
ing the vehicle. WARNING

sudden braking, sudd en 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.

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.

■
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 sh oulder 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 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) The front seat belt buckles move out-
ward automatically for easier access. 
When entering the vehicle

belt buckle for the corresponding seat
will move outward automatically. The
buckle will retract automatically after
the plate is inserted and locked to the
buckle. 
When exiting the vehicle (driver’s
seat only)
If the power switch is turned off when
the driver’s seat belt is fastened, the
driver’s seat belt buckle will move out-
ward. The buckle will retract automati-
cally when the driver’s seat belt is
released. *

For safety and security WARNING
• 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. ●
If the seat belt extender has been con-
nected to the front seat belt buckles
but the seat belt extender has not also
been fastened to the latch plate of the
seat belt, the SRS front airbags will
judge that the driver and front passen-
ger are wearing the seat belt even
though the seat belt has not been con-
nected. In this case, the SRS front air-
bags 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 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.
