Seat, seatbelt and SRS airbags
– CONTINUED –
The SRS airbag can function only when the ignition
switch is in the “ON” position.
If the sensors detect a certain predetermined amount
of force during a frontal collision, the control module
sends signals to the frontal airbag modules instructing
them to inflate the SRS frontal airbags. Then both air-
bag modules produce gas, which instantly inflates
driver’s and passenger’s SRS frontal airbags. After the
deployment, the SRS airbags immediately start to de-
flate so that the driver’s vision is not obstructed. The
time required from detecting impact to the deflation of
the SRS airbag after deployment is shorter than the
blink of an eye.
The front passenger’s SRS frontal airbag deploys to-
gether with driver’s SRS frontal airbag even when no
one occupies the front passenger’s seat.
Although it is highly unlikely that the SRS airbag would
activate in a non-accident situation, should it occur,
the SRS airbag will deflate quickly, not obscuring vi-
sion and will not interfere with the driver’s ability to
maintain control of the vehicle.
When the SRS airbag deploys, a sudden, fairly loud
inflation noise will be heard and some smoke will be
released. These occurrences are normal result of the
deployment. This smoke does not indicate a fire in the
vehicle.
Do not touch the SRS airbag system compo-
nents around the steering wheel and dash-
board with bare hands right after deployment.
Doing so can cause burns because the compo-
nents can be very hot as a result of deployment.
The SRS frontal airbag is designed to deploy in the
event of an accident involving a moderate to severe
frontal collision. It is basically not designed to deploy
in lesser frontal impacts because the necessary pro-
tection can be achieved by the seatbelt alone. Also, it
is basically not designed to deploy in side or rear im-
pacts or in roll-over accidents because deployment of
the SRS frontal airbag would not help the occupant in
those situations. The SRS airbag is designed to func-
tion on a one-time-only basis.
SRS airbag deployment depends on the level of force
experienced in the passenger compartment during a
collision. That level differs from one type of collision to
another, and it may have no bearing on the visible
damage done to the vehicle itself.
