this is indeed the self leveling system warning light. the system is inactive .
this could be caused by a few things, the most likely being a rupture to the air spring on the one side. other possible issues could be with the air distribution system of possibly a level sensor (although unlikely as this vehicle should only have as ingle sensor for the rear end)
it terms of being safe to drive, it isn't really. if he needs to limp it a few miles home or a few miles to a garage, that is probably doable if he takes care to drive slow and avoid bumps. If he needs to drive a long distance or wants to continue using the car normally for many weeks, that would not be advisable.
the vehicle will rquire professional repair (likely air spring replacement). if he can limp it to a close BMW garage I would do that. otherwise I would have it towed
