What does the ECO light on the Buick Excelle dashboard mean?

ECO indicates that the vehicle's eco-driving mode is activated. ECO is an English abbreviation derived 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 light on the dashboard illuminates, it signifies that the vehicle's eco mode is enabled. Eco mode is categorized into active and passive types. The difference lies in the fact that the active type has a dedicated button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately illuminates, and the vehicle automatically adjusts 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 dashboard ECO indicator light turns on, 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 light. Most vehicles employ the active Eco-driving mode, meaning they have a dedicated switch button. Thus, during daily driving, you can activate the Eco mode. 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 only fail to demonstrate the fuel-saving characteristics of Eco mode but also affect the vehicle's power output. Additionally, the Eco mode typically becomes ineffective under the following conditions: When the vehicle speed exceeds 120 kilometers per hour, the system 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.
When driving my Buick Excelle, I noticed the ECO light on the dashboard illuminated, indicating the economy mode is activated, meaning the current driving is fuel-efficient. For example, the system might automatically trigger based on my driving habits, such as driving smoothly without sudden acceleration, or pressing the ECO button in the car. This adjusts engine power or transmission shift points, helping to reduce fuel consumption by about 10%, which can save a significant amount on fuel costs in the long run and is also more environmentally friendly by lowering emissions. Common scenarios like city driving or highway cruising with the ECO light on are good signs, indicating everything is normal. I don’t worry about it falsely indicating a fault; instead, seeing it reminds me to maintain gentle driving. If it doesn’t light up, I try to improve my habits, such as maintaining a steady speed. In summary, ECO is quite practical for budget-conscious car owners and encourages a more eco-friendly lifestyle. After driving the Excelle for several years, this indicator has always been my little helper in saving fuel.
