SRS airbag system warning light
A diagnostic system continually monitors
the readiness of the SRS airbag system
(including front seatbelt pretensioners)
with the ignition switch in the “ON” position.
The SRS airbag system warning light will
show normal system operation by illuminating
for approximately 6 seconds when
the ignition switch is turned to the “ON”
position...
The SRS side airbag and SRS curtain
airbag are designed as follows:
To deploy in the event of an accident
involving a moderate to severe side impact
collision
To function on a one-time-only basis
The SRS side airbag and SRS curtain
airbag are not designed to deploy in the
following cases:
In most lesser side impacts
In most frontal or most rear impacts
(because the SRS side airbag and SRS
curtain airbag deployment would not protect
the occupant in those situations)
The SRS curtain airbags are also designed
to deploy when the vehicle is in an
extremely inclined state such as during a
rollover...
