If the bulb of the right or left outer rear position light fails in parking light mode, the inner rear position light is activated as a replacement.
There is a risk of accident!
To ensure the safe operation of your vehicle, a faulty bulb should be replaced as soon as possible.
Note: The failure of the incandescent lamp is indicated on the multi-function display (Section Warning and indicator lamps, as well as multi-information display messages about registered faults).
