For safety and security
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

WARNING
■If a safety system warning light does
not come on
Should a safety system light such as the
ABS and SRS warning lights not come on
when you start the hybrid system, this
could mean that these systems are not
available to help protect you in an acci-
dent, which could result in death or seri-
ous injury. Have the vehicle inspected by
your Lexus dealer immediately if this
occurs.
