Front impact sensors
Airbag sensor assembly
The main SRS airbag system components are shown above. The SRS airbag system is con-
trolled by the airbag sensor assembly. 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 occu-
pants.
Q If the SRS airbags deploy (inflate)
O Slight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.
O A loud noise and white powder will be
emitted.
O 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.
O The windshield may crack.
O All of the doors will be unlocked.
(oP.143)
O The brakes and stop lights will be con-
trolled automatically. (oP.431)
O The interior lights will turn on automati-
cally. (oP.475)
O The emergency flashers will turn on auto-
matically. (oP.574)
O Fuel supply to the engine will be stopped.
(gasoline engine) (oP.581)
O Vehicles with eCall: If any of the following
situations occur, the system is designed
to send an emergency call
*
to the eCall
control center, notifying them of the vehi-
cle’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
assistance required. If the occupants are
unable to communicate, the agent auto-
matically treats the call as an emergency
and helps to dispatch the necessary
emergency services. (oP.104)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-
end collision.
• The vehicle is involved in a rollover acci-
dent while the “RSCA OFF” indicator is
on.
*
: In some cases, the call cannot be made.
(oP.105)
Q SRS airbag deployment conditions (SRS
front airbags/SRS seat cushion airbags
(if equipped))
O The SRS front airbags and SRS seat cush-
ion airbags will deploy in the event of an
impact that exceeds the set threshold
level (the level of force corresponding to
an approximately 20 - 30km/h [12 - 18
mph] frontal collision with a fixed wall that
does not move or deform).
However, this threshold 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 underrides, or goes
under, the bed of a truck
O Depending on the type of collision, it is
possible that only the seat belt preten-
sioners and SRS seat cushion airbags will
activate.
O Vehicles with SRS seat cushion airbags:
The SRS seat cushion airbags on the rear
seat will not operate if the occupant is not
wearing a seat belt.
Q SRS airbag deployment conditions (SRS
side and curtain shield airbags)
O The SRS side and curtain shield airbags
will deploy in the event of an impact that
