RX450hL: Rear side airbags (outboard second-row seats)
Your vehicle is equipped with ADVANC ED AIRBAGS designed based on the US
motor vehicle safety standards (FMVSS20 8). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtain ed from the sensors etc.
shown in the system components diagram above. This information includes crash
severity and occupant information. As th e airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with no n-toxic gas to help restrain the motion of
the occupants.
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
●A loud noise and white powder will be
emitted.
●Parts of the airbag module (steering
wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front
and rear pillars, and roof side rails, may
be hot for several minutes. The airbag
itself may also be hot.
●The windshield may crack.
●The hybrid system will be stopped and
fuel supply to the engine will be stopped.
( P.72)
●All of the doors will be unlocked.
(P.110)
●The brakes and stop lights will be con-
trolled automatically. ( P.279)
●The interior lights will turn on automati-
cally. (P.316)
●The emergency flashers will turn on auto-
matically. ( P.402)
●For Lexus Enform Safety Connect sub-
scribers, if any of the following situations
occur, the system is designed to send an
emergency call to the response center,
notifying them of the vehicle’s location
(without needing to push the “SOS” but-
ton) and an agent will attempt to speak
with the occupants to ascertain the level
of emergency and assi stance required. If
the occupants are unable to communi-
cate, the agent automatically treats the
call as an emergency and helps to dis- patch the necessary emergency services.
(
P.60)
• An SRS airbag is deployed.
• A seat belt preten sioner is activated.
• The vehicle is involved in a severe rear-end collision.
■SRS airbag deployment conditions (SRS
front airbags)
●The SRS front airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to an approximately 12 - 18
mph [20 - 30 km/h] frontal collision with
a fixed wall that does not move or
deform).
However, this threshol d velocity will be
considerably higher in the following situa-
tions:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can
move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “u nderrides”, or goes
under, the bed of a truck
●Depending on the type of collision, it is
possible that only the seat belt
pretensioners will activate.
●The SRS seat cushion airbag on the front
passenger seat will not operate if the
occupant is not wearing a seat belt.
■SRS airbag deployment conditions (SRS
side and curtain shield airbags)
●The SRS side and curtain shield airbags
will deploy in the event of an impact that
exceeds the set threshold level (the level
of force corresponding to the impact
force produced by an approximately
3300 lb. [1500 kg] vehicle colliding with

For safety and security
The SRS curtain shield airbags do not gen-
erally inflate if the vehicle is involved in a
rear collision, if it pitches end over end, or if
it is involved in a low-speed side or
low-speed frontal collision.
●Collision from the rear
●Pitching end over end
■When to contact your Lexus dealer
In the following cases, the vehicle will
require inspection and/or repair. Contact
your Lexus dealer as soon as possible.
●Any of the SRS airbags have been
inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an accident
that was not severe enough to cause the
SRS front airbags to inflate.
●A portion of a door or its surrounding
area is damaged, deformed or has had a
hole made in it, or the vehicle was
involved in an accident that was not
severe enough to cause the SRS side and
curtain shield airbags to inflate.
●The pad section of the steering wheel,
dashboard near the front passenger
airbag or lower portio n of the instrument
panel is scratched, cracked, or otherwise
damaged.
●The front passenger’s seat cushion sur-
face is scratched, cracked, or otherwise
damaged.
●The surface of the seats with the SRS side
airbag is scratched , cracked, or other-
wise damaged.
●The portion of the fron t pillars, rear pillars
or roof side rail ga rnishes (padding) con-
taining the SRS curtain shield airbags
inside is scratched, cracked, or otherwise
damaged.

381-1. For safe use
WARNING
●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 other
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
airbags and SRS seat cushion airbag
inflate as they may interfere with infla-
tion of the SRS airbags. Such accesso-
ries may prevent the side airbags and
SRS seat cushion airbag from activat-
ing correctly, disable the system or
cause the side airbags and SRS seat
cushion airbag 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
airbags 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
airbags for the front passenger may
not deploy in the event of a collision.
■Modification and disposal of SRS
airbag 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, remova l, 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)
●Repairs or modifications of the front
fender, front bumper, or side of the
occupant compartment
●Installation of a grille guard (bull bars,
kangaroo bar, etc. ), snow plows,
winches or roof luggage carrier
●Modifications to the vehicle’s suspen-
sion system

Observe the following precautions
when children are in the vehicle.
Use a child restraint system appro-
priate for the child, until the child
becomes large enough to properly
wear the vehicle’s seat belt.
It is recommended that children
sit in the rear seats to avoid acci-
dental contact with the shift lever,
wiper switch, etc.
 Use the rear door child-protector
lock or the window lock switch to
avoid children op ening the door
while driving or operating the
power window accidentally.

equipment which may catch or
pinch body parts, such as the
power window, hood, back door,
seats etc.
WARNING
■When children are in the vehicle
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playin g with the windows,
the moon roof or panoramic moon roof,
or other features of the vehicle. In addi-
tion, heat build-up or extremely cold
temperatures inside the vehicle can be
fatal to children.
Child restraint systems
Before installing a child restraint
system in the vehicle, there are pre-
cautions that need to be observed,
different types of child restraint sys-
tems, as well as installation meth-
ods, etc., written in this manual.
Use a child restraint system when
riding with a small child that cannot
properly use a seat belt. For the
child’s safety, install the child
restraint system to a second-row
seat. Be sure to follow the installa-
tion method that is in the operation
manual enclosed with the restraint
system.

●Do not attach window tint to the wind-
shield.
●Replace the windshield if it is damaged
or cracked.
After replacing the windshield, the
front camera must be recalibrated.
Contact your Lexus dealer for details.
●Do not allow liquids to contact the
front camera.
●Do not allow bright lights to shine into
the front camera.
●Do not dirty or damage the front cam-
era.
When cleaning the inside of the wind-
shield, do not allow glass cleaner to

2854-6. Driving tips
4
Driving
Control and maintain the vehicle at a
constant speed. Before stopping at a
toll booth or similar, allow plenty of
time to release the accelerator and
gently apply the brakes. A greater
amount of electrical energy can be
regenerated when slowing down.
Use the air conditioning only when
necessary. Doing so can help reduce
excessive gasoline consumption.
In summer: When the ambient tem-
perature is high, use the recirculated
air mode. Doing so will help to reduce
the burden on the air conditioning sys-
tem and reduce fuel consumption as
well.
In winter: Because the gasoline engine
will not automatically cut out until it and
the interior of the vehicle are warm, it
will consume fuel. Also, fuel consump-
tion can be improved by avoiding over-
use of the heater.
Make sure to check the tire inflation
pressure frequently. Improper tire infla-
tion pressure can cause poor fuel
economy.
Also, as snow tires can cause large
amounts of friction, their use on dry
roads can lead to poor fuel economy.
Use tires that are appropriate for the
season. Carrying heavy luggage will lead to
poor fuel economy. Avoid carrying
unnecessary luggage.
Installing a large
roof rack will also cause poor fuel
economy.
Since the gasoline engine starts up and
cuts out automatically when cold,
warming up the engine is unnecessary.
Moreover, frequently driving short dis-
tances will cause the engine to repeat-
edly warm up, which can lead to excess
fuel consumption.
