Nissan LEAF 2023 Owners Manual
5.6.2.2. Front seat-mounted side-impact supplemental air bag system
The front seat-mounted side-impact supplemental air bag is located at the outside of the front seats' seatbacks.
The front seat-mounted side-impact supplemental air bag system is designed to inflate in higher severity side collisions, although it may inflate if the forces in another type of collision are similar to those of a higher severity side impact. It may not inflate in certain side collisions. Vehicle damage (or lack of it) is not always an indication of proper front seat-mounted side-impact supplemental air bag system operation.
