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

2564-5. Using the driving support systems
(such as those used at railroad crossings,
toll gates and parking lots)
●When there is a rut or hole in the surface
of the road
●When driving on a metal cover (grating),
such as those used for drainage ditches
●When driving up or down a steep slope
●If a sensor is hit by a large amount of
water, such as when driving on a flooded
road
●There is dirt, snow, water drops or ice on
a sensor. (Cleaning the sensors will
resolve this problem.)
●A sensor is coated with a sheet of spray
or heavy rain
●When driving in inclement weather such
as fog, snow or a sandstorm
●When strong winds are blowing
●When vehicle horns, vehicle detectors,
motorcycle engines, air brakes of large
vehicles, the clearance sonar of other
vehicles or other devices which produce
ultrasonic waves are near the vehicle
●If the front of the vehi cle is raised or low-
ered due to the carried load
●If the orientation of a sensor has been
changed due to a collision or other
impact
●The vehicle is approaching a tall or
curved curb
●Driving close to columns (H-shaped steel
beams, etc.) in multi-story parking
garages, construction sites, etc.
●If the vehicle cannot be driven in a stable
manner, such as when the vehicle has
been in an accident or is malfunctioning
●On an extremely bumpy road, on an
incline, on gravel, or on grass
●When a tire chains, compact spare tire or
an emergency tire punc ture repair kit is
used
■Detection range of the sensors
Approximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 2.0 ft. (60 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect objects that are extremely close to
the vehicle.
The range of the sensors may change
depending on the shap e of the object, etc.
