The E70 has a couple of functions:

1. When you unlock the car, the angel-eyes, tail-lights, internal lights and lights on the door handles come on - I don't think you can set the time delay in the idrive though - could be wrong there though - not tried.
2. When you stop the car you have the option to switch the headlights on by using the flash - this then stays on for a period set via iDrive - called pathway lighting function.
