2020 LEXUS LS500 airbag disable

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)

■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-facing child restraint
system is installed on the front passen-
ger seat.
