weight LEXUS LS500 2020 Owners Manual

281-1. For safe use
When the vehicle speed reaches
approximately 12 mph (20 km/h) or
higher, the seat belts will retract slightly
to remove any slack.
If the system determines that a collision
is unavoidable, the front seat belts will
retract before the collision. ( P.206)
■Pre-collision seat belts with comfort
function
A motor sound may be heard when a front
seat belt is released or a front door is
opened. This does not indicate a malfunc-
tion.
■Customization
Some functions can be customized.
(  P.470)
WARNING
●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 pre-
tensioner for the front passenger’s seat
may not activate in the event of a colli-
sion.
●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.

361-1. For safe use
WARNING
●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.
●Do not attach anything to areas such
as a door, windshield, 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.
●If the areas where the SRS airbags are
stored, such as the steering wheel pad
and front and rear pillar garnishes are
damaged or cracked, have them
replaced by your Lexus dealer.
●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 SRS front air-
bags for the front passenger may not
deploy in the event of a collision.
■Modification and disposal of SRS air-
bag system components
Do not dispose of your vehicle or per-
form any of the following modifications
without consulting your Lexus dealer.
The SRS airbags may malfunction or
deploy (inflate) accidentally, causing
death or serious injury.
●Installation, removal, disassembly and
repair of the SRS airbags
●Repairs, modifications, removal or
replacement of the steering wheel,
instrument panel, dashboard, seats or
seat upholstery, front, side and rear pil-
lars, roof side rails, front door panels,
front door trims or front door speakers
●Modifications to the front door panel
(such as making a hole in it)

For safety and security
WARNING
●Make sure the “AIR BAG OFF” indica-
tor light is not illuminated when using
the seat belt extender for the front pas-
senger seat. If the “AIR BAG OFF”
indicator light is illuminated, discon-
nect the extender tongue from the seat
belt buckle, and reconnect the seat
belt. Reconnect the seat belt extender
after making sure the “AIR BAG ON”
indicator light is illu minated. If you use
the seat belt extender while the “AIR
BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front
passenger will not activate, which
could cause death or serious injury in
the event of a collision.
●Do not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket).
●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 illuminated, 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.

461-2. Child safety
tions for child restraint systems.
 Use a child restraint system until the
child becomes large enough to
properly wear the vehicle’s seat belt.
 Choose a child restraint system that
suits your vehicle and is appropriate
to the age and size of the child.
■Types of child restraint system installation methods
Confirm with the operation manual enclosed with the child restraint system about
the installation of the child restraint system.
WARNING
■When a child is riding
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●For effective protection in automobile
accidents and sudden stops, a child
must be properly restrained, using a
seat belt or child restraint system
which is correctly installed. For installa-
tion details, refer to the operation man-
ual enclosed with the child restraint
system. General insta llation instruction
is provided in this manual.
●Lexus strongly urges the use of a
proper child restraint system that con-
forms to the weight and size of the
child, installed on the rear seat.
According to accident statistics, the
child is safer when properly restrained
in the rear seat than in the front seat.
●Holding a child in your or someone
else’s arms is not a substitute for a child
restraint system. In an accident, the
child can be crushe d against the wind-
shield or between the holder and the
interior of the vehicle.
■Handling the child restraint system
If the child re straint system is not prop-
erly fixed in place, the child or other pas-
sengers may be seriously injured or even
killed in the event of sudden braking, sud-
den swerving, or an accident.
●If the vehicle were to receive a strong
impact from an accident, etc., it is pos-
sible that the child restraint system has
damage that is not readily visible. In
such cases, do not reuse the restraint
system.
●Make sure you have complied with all
installation instructions provided with
the child restraint system manufac-
turer and that the system is properly
secured.
●Keep the child rest raint system prop-
erly secured on the seat even if it is not
in use. Do not store the child restraint
system unsecured in the passenger
compartment.
●If it is necessary to detach the child
restraint system, remove it from the
vehicle or store it securely in the trunk.

Before driving
WARNING
●Remove any heavy loads, such as snow
and ice, from the trunk lid before
opening it. Failure to do so may cause
the trunk lid to suddenly shut again
after it is opened.
●When opening or closing the trunk lid,
thoroughly check to make sure the
surrounding area is safe.
●If anyone is in the vicinity, make sure
they are safe and let them know that
the trunk is about to open or close.
●Use caution when opening or closing
the trunk lid in windy weather as it may
move abruptly in strong wind.
●The trunk lid may suddenly shut if it is
not opened fully. It is more difficult to
open or close the trunk lid on an
incline than on a level surface, so
beware of the trunk lid unexpectedly
opening or closing by itself. Make sure
that the trunk lid is fully open and
secure before using the trunk.
●When closing the trunk lid, take extra
care to prevent your fingers etc. from
being caught.
●When closing the trunk lid, make sure
to press it lightly on its outer surface. If
the trunk handle is used to fully close
the trunk lid, it may result in hands or
arms being caught.
●Do not attach any accessories other
than genuine Lexus parts to the trunk
lid. Such additional weight on the trunk
lid may cause the lid to suddenly shut
again after it is opened.
■Trunk easy closer
In the event that the trun k lid is left slightly
open, the trunk easy closer will automati-
cally close it to the fully closed position. It
takes several seconds before the trunk
easy closer begins to operate. Be careful
not to catch fingers or anything else in
the trunk lid, as this may cause bone frac-
tures or other serious injuries.
■Power trunk opener and closer (if
equipped)
Observe the following precautions when
operating the power trunk opener and
closer.
Failure to do so may cause serious injury.
●Check the safety of the surrounding
area to make sure there are no obsta-
cles or anything that could cause any
of your belongings to get caught.
●If anyone is in the vicinity, make sure
they are safe and let them know that
the trunk is about to open or close.
●If the trunk closer switch is pressed
while the trunk lid is opening during
automatic operation, the trunk lid
stops opening. Take extra care when
on an incline, as the trunk lid may open
or close suddenly.
