Airbag sensor assembly
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 sever-
ity 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 (inflation) by
hot gases.
●
A loud noise and white powder will
be emitted.
●
Parts of the airbag module (steer-
ing 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. 74 )
●
The brakes and stop lights will be
controlled automatically. (P.221)
●
The interior lights will turn on auto-
matically. (P.368)
●
The emergency flashers will be
turned on automatically. (P.442)
●
For Safety Connect subscribers, 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” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. (P.6 2)
• An SRS airbag is deployed.
• A seat belt pretensioner is acti-
vated.
• The vehicle is involved in a severe
rear-end collision.
■
SRS airbag deployment condi-
tions (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 corresponding
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 considerably higher in the follow-
ing 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 colli-
sion in which the front of the vehi-
cle “underrides”, 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 front airbags for the front
passenger will not activate if there
is no passenger sitting in the front
