What the Door Ajar Warning Light Means on a Mercedes-Benz V-Class
On the Mercedes-Benz V-Class, this symbol shows an open or improperly closed door. If all doors are shut but the light stays on, a worn door switch is the usual culprit.
How Urgent Is the Door Ajar Warning Light?
In terms of priority, treat this as a low concern on your Mercedes-Benz V-Class.
