What is the Mercedes ECO mode?

[LeDaniela]

ECO refers to the car's economical driving mode function. ECO is an English abbreviation formed from Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and passive Eco driving mode. When the Eco indicator on the dashboard lights up, it indicates that the vehicle's economical mode has been activated. Eco mode is categorized into active and passive modes. The difference lies in the fact that the active mode has a dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator lights up, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The passive Eco mode does not have a dedicated button. When the Eco indicator on the dashboard lights up, it serves merely as a reminder. The Eco system automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will simultaneously display the Eco indicator. Most cars employ the active Eco driving mode, meaning they have a dedicated switch button. During everyday driving, the Eco mode can be activated. However, it is unnecessary to enable Eco mode when driving at speeds exceeding 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not highlight the fuel-saving characteristics of Eco mode and could instead affect the vehicle's power. Additionally, the Eco mode typically becomes ineffective under the following circumstances: When the vehicle speed exceeds 120 kilometers per hour, the car prioritizes speed, causing the Eco mode to deactivate automatically. During idle parking or when in N/P gear or manual mode, the Eco mode may also become ineffective. When high torque output is required, such as when climbing a hill, the engine control unit prioritizes delivering sufficient power to drive the vehicle, and the Eco mode will not function.
