n Examples of the types of accidents in which the SRS side air-
bag will basically not deploy.
The SRS side airbag is basically not designed to deploy if the vehicle
is involved in a frontal collision or is struck from behind. Examples of
such accidents are illustrated below.
The vehicle is involved in a frontal
collision with another vehicle (moving
or stationary).
In an accident where the vehicle is struck from the side more than
once, the SRS side airbag deploys only once on the first impact.
Example: In the case of a double side impact collision, first with one
vehicle and immediately followed by another from the same direction,
the SRS side airbag is activated on the first impact but not on the se-
cond.
1-46
The vehicle is struck from behind.
