Hyundai Elantra: Why Didn't My Air Bag Go Off in a Collision? / Air bag inflation conditions
Front air bags
Front air bags and the driver’s knee air bag are designed to inflate in a frontal collision depending on the the severity of impact of the front collision.
Side and curtain air bags
Side and curtain air bags are designed to inflate when an impact is detected by side collision sensors depending on the severity of impact resulting from a side impact collision.
Although the driver’s and front passenger’s air bags are designed to inflate only in frontal collisions, they also may inflate in other types of collisions if the front impact sensors detect a sufficient impact. Side and curtain air bags are designed to inflate only in side impact collisions or rollover situations, but they may inflate in other collisions if the side impact sensors detect a sufficient impact.
If the vehicle chassis is impacted by bumps or objects on unimproved roads, the air bags may deploy. Drive carefully on unimproved roads or on surfaces not designed for vehicle traffic to prevent unintended air bag deployment.
Why Didn't My Air Bag Go Off in a Collision?
There are certain types of accidents in which the air bag would not be expected
to provide additional protection. These include rear impacts, second or third collisions
in multiple impact accident ...
Air bag non-inflation conditions
In certain low-speed collisions the air bags may not deploy. The air bags are
designed not to deploy in such cases because they may not provide benefits beyond
the protection of the seat belts.
