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.
Adaptive rear light function
The rear position lamps have an adaptive function. The brightness of the rear position lamps is adapted depending on the light conditions in the surroundings. When it is light outside, the rear position lamps are illuminate more brightly to make them more visible to other vehicles. When it is dark outside, the rear position lamps illuminate less brightly to avoid dazzling other vehicles.
Number plate lighting and trailer lighting are not affected by the adaptive function.
