The main SRS airbag system components are shown above. The SRS airbag sys-
tem is controlled 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 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

threshold level (the level of force corre-
sponding to an approximately 20 - 30
km/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
Depending on the type of collision, it is
●
possible that only the seat belt
pretensioners will activate.

classification system: The SRS front
airbags for the front passenger will not
