The rear fog light symbol appears in the driver display showing the light is active.
The rear fog light is switched off automatically if the rotating ring on the left-hand stalk is changed to the 0 position.
Note
When you connect a trailer the rear fog light may not illuminate as the rear fog light functionality is instead transferred to the trailer. Check if the trailer is equipped with a rear fog light before activating the rear fog light to ensure safe operation.
