Hyundai Tucson: Why Didn’t My Air Bag Go Off in a Collision? (Air bags are not designed to inflate in every collision.) / Air bag inflation conditions
Front air bag
Front air bags are designed to inflate in a frontal collision depending on the intensity, speed, or angles of impact of the front collision.
Side impact and curtain air bags
Side impact and curtain air bags are designed to inflate when an impact is detected by side collision sensors depending on the strength, speed, or angles 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 impact 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.

WARNING
To reduce the risk of an air bag deploying unexpectedly and causing serious
injury or death:
Do not hit or allow any objects to impact the locations where air bags
or sensors are ins ...
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 ...
