351-1. For safe use
LS500h_OM_OM50F42U_(U) 1
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.

36 1-1. For safe use
LS500h_OM_OM50F42U_(U) WARNING●
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 towa rd 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 in strument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy. ●
Do not attach anything to areas such
as a door, windshie ld, side windows,
front or rear pillar, roof side rail and
assist grip.
●
Do not hang coat hangers or hard
objects on the coat hooks. All of these
items could become projectiles and
may cause death or serious injury,
should the SRS curtain shield airbags
deploy. ●
If a vinyl cover is put on the area where
the SRS knee airbag will deploy, be
sure to remove it. ●
Do not use seat accessories which
cover the parts where the SRS side air-
bags inflate as they may interfere with
inflation of the SRS airbags. Such
accessories may prevent the side air-
bags from activating correctly, disable
the system or cause the side airbags to
inflate accidentally, resulting in death
or serious injury.
●
Do not strike or apply significant levels
of force to the area of the SRS airbag
components or the front doors. Doing
so can cause the SRS airbags to mal-
function.
●
Do not touch any of the component
parts immediately after the SRS air-
bags have deployed (inflated) as they
may be hot.
●
If breathing becomes difficult after the
SRS airbags have deployed, open a
door or window to allow fresh air in, or
leave the vehicle if it is safe to do so.
Wash off any residue as soon as possi-
ble to prevent skin irritation.

48 1-2. Child safety
LS500h_OM_OM50F42U_(U) lowest position (if equipped).
 Adjust the pelvic support to the low-
est position.
 Adjust the seatback side bolster to
the widest position (if equipped).
 Adjust the seat cushion side bolster
to the lowest position (if equipped).
 Adjust the hip support to the lowest
position (if equipped).
 If the head restraint interferes with
the child restraint system installa-
tion and the head restraint can be
removed, remove the head restraint.
Otherwise, put the head restraint in
the upper most position.
■
When installing a child restraint
system to a power rear seat (if
equipped)
When using a child restraint system in
an outer rear seat, adjust the seat as
follows and install the child restraint
system.
 Adjust the seat cushion to the fully
rearward position.
 Adjust the upper seatback to the
rearmost position.
 Adjust the front of the seat cushion
to the lowest position.  Adjust the head restraint to the low-
est and rearmost position.
 Adjust the shoulder bolster to the
lowest position.
 Adjust the lumbar support to the
lowest position.
 Adjust the pelvic support to the low-
est position.
 Disable the automatic rear seat
operation. ( → P.318)
 For the rear seat with an ottoman (if
equipped): Adjust the seatback to
the most upright position and otto-
man (footrest) to the stowed posi-
tion.
WARNING
■
When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●
Never install a rear-facing child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-fac ing child restraint
system is installed on the front passen-
ger seat.

52 1-2. Child safety
LS500h_OM_OM50F42U_(U) ■
Booster seat
1 If installing the child restraint sys-
tem to the front passenger seat is
unavoidable, refer to P.47 for front
passenger seat adjustment.
2 Place the child restraint system on
the seat facing the front of the vehi-
cle. 
Booster type 
High back type
4 Sit the child in the child restraint
system. Fit the seat belt to the child
restraint system according to the
manufacturer’s in structions and
insert the plate into the buckle.
Make sure that the belt is not
twisted.Check that the shoulder belt is correctly
positioned over the child’s shoulder and
that the lap belt is as low as possible. ( → P.24)
■
Removing a child restraint system
installed with a seat belt
Press the buckle release button and
fully retract the seat belt. When releasing the buckle, the child
restraint system may sp ring up due to the
rebound of the seat cushion. Release the
buckle while holding down the child
restraint system.
Since the seat belt auto matically reels itself,
slowly return it to the stowing position.

When installing a child restraint sys-
tem
