What the Door Ajar Warning Light Means on a Mercedes-Benz GLE Coupe
On the Mercedes-Benz GLE Coupe, 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?
Urgency level for this indicator on the Mercedes-Benz GLE Coupe: low. Reading the colour is the fastest gut-check — a red symbol asks you to stop and investigate quickly, while amber or yellow means schedule a check soon rather than immediately. Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the Door Ajar Warning Light appeared, how the Mercedes-Benz GLE Coupe is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.

Can I keep driving with the Door Ajar Warning Light on?
For a Mercedes-Benz GLE Coupe, a steady amber Door Ajar Warning Light with normal driving generally allows a careful trip to a garage. A red or flashing light, or any change in performance, means you should stop and avoid further driving until the fault is identified.
