What the ECO Mode Light Means on a Infiniti Q50
On the Infiniti Q50, an ECO indicator means economy mode is active (or you are driving efficiently). It reduces fuel use at the expense of a little responsiveness.
How Urgent Is the ECO Mode Light?
Urgency level for this indicator on the Infiniti Q50: 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 ECO Mode Light appeared, how the Infiniti Q50 is behaving, and whether the light is steady or flashing, because a flashing warning almost always means act now.
