How Urgent Is the ECO Mode Light?
Urgency level for this indicator on the Mercedes-Benz GLC Coupe: low.

Green and blue symbols are simply telling you a system is active. Whatever the colour, the safest habit is to note when the ECO Mode Light appeared, how the Mercedes-Benz GLC Coupe is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
