Turn the rotating ring to the 
position (number plate lighting is switched on at the same time).
If the car's electrical system is in ignition position II or the engine is running then the daytime running lights are switched on instead of the front position lamps.
If the tailgate is opened when it is dark outside, the rear position lamps come on (if not already switched on) to warn road users approaching from behind. This takes place irrespective of the position of the rotating ring or the ignition position of the car's electrical system.
