Nissan X-Trail e-POWER 2023 Owners Manual
4.5.2.4. Supplemental curtain side-impact air bag system
The supplemental curtain side-impact air bag is located at the roof rails.
The supplemental curtain side-impact 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 supplemental curtain side-impact air bag system operation.
