Rear side airbags
Q
Side impact sensors (front door)
R
Your vehicle is equipped with ADVANCED AIRBAGS designed based on the US
motor vehicle safety standards (FMVSS208). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtained from the sensors etc.
shown in the system components diagram above. This information includes crash
severity and occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with non-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.68)
● All of the doors will be unlocked.
(P.109)
The brakes and stop lights will be con-
●
trolled automatically. (P.259)
The interior lights will turn on automati-
●
cally. (P.292)
● The emergency flashers will turn on auto-
matically. (P.378)
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 assistance required. If
the occupants are unable to communi-
1-1. For safe use
cate, the agent automatically treats the
call as an emergency and helps to dis-
patch the necessary emergency services.
(P.56)
• An SRS airbag is deployed.
• A seat belt pretensioner 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 threshold velocity will be con-
siderably higher in the following situations:
• 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 underrides, or goes
under, the bed of a truck
● Depending on the type of collision, it is
possible that only the seat belt preten-
sioners will activate.
The SRS front airbags for the front pas-
●
senger will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the SRS front airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied.
