Problem with the interior lights
I'm having a problem with the interior lights.
The interior lights and the lights in the doors don't turn on automatically when I open one of the doors.
The lights starts to work when I turn the ignition on. They also work when I stop the car and turn of the ignition.
If I try again after the car has gone into "sleep mode" it won't work. I have to turn the ignition on again to get it work.
Does anyone have experienced this problem and have some advice or a solution?

Perhaps a low accessoiry battery?
Have had this when the acc. battery was empty ,also my keyless entry would not work and I had to use the key to get in.After charging the battery (driving for some time) everything came back to life.

Yes, it could be the battery. I was on a 2 hour trip today, and after that the lights works ok. I have done this before and after a couple of days the lights stop working again.
I have not been able to check the battery in the trunk yet. I can't find the battery anywhere in trunk(!).
Do anybody know where the consumer battery is located?

After some searching I found that the battery is located at the right side behind the rear seat.
But I can't figure how to remove the panel behind the seat?

Its in the trunk behind the rear seats right hand side ,from the top of my head its undoing the trunk bottompanel and or side ones (may not be neccessairy, its been a while for me) with the screws. Then if you carefully pull the vertical panel in the trunk behind the rear seats, you should be able to get to it.

Thank you marthyh.
The light did not work this morning after driving 180 km yesterday, so I'm going to check the battery next.
Not a big issue, but very annoying

Thank you blaine.sellie. Not silly at all 
I have checked it allready, I was not the switch.
I've been in touch with MB today. They said that it could be the some wrong with the CAN bus. The CAN bus shuts down the light. When I turn on the ignition LIN takes over and turn the lights back on.
It seems like I have to connect the car to a Star unit to sort this out.
