1-1. For safe use
bag 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.

●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed of deployment (inflation) by
hot gases.
■The SRS airbags deploy in a
frontal impact when
●A loud noise and white powder will
be emitted.
●The following SRS airbags will
deploy in the event of an impact
that exceeds a threshold level
(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):
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the parts
around the airbags 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.87)
●The brakes and stop lights will be
controlled automatically.
(P.425)
●The interior lights will turn on auto-
matically. (P.446)
●The emergency flashers will turn
on automatically. (P.546)
●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

●The threshold level at which the
SRS airbags will deploy will be
higher than normal in the in the
following situations:
• When the vehicle collides with an
object, such as a parked vehicle
or sign pole, which moves or
deforms 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,
only the following may deploy:
• Seat belt pretensioners
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
●The SRS airbags for the front pas-
senger’s seat will not deploy if
there is no passenger in the front
passenger seat. However, the
SRS airbags for the front passen-
ger’s seat may deploy, even if the
seat is unoccupied, if luggage is
put on the seat.
