Second row passenger's seats can be adjusted manually.
An unsecured seat or seat-back can move out of position or collapse without warning if there is sudden acceleration or stop or in a crash.
A seat or seat-back that suddenly moves or collapses can result in severe injury or death.
Always make sure all seats and seat-backs are securely locked into position before driving.
Ensuring seats are locked into place:
Once the desired seat position and seat-back angles are made, rock the seat back and forth to make sure they are locked into position. There should be no movement.
