Can the GS4 frequently use ECO mode?

[Tiffany]

You can frequently use the ECO mode in your car. ECO mode, also known as Economy Mode, is particularly effective in saving fuel when driving in congested urban traffic conditions. Under ECO mode, the carbon buildup in the engine is almost the same as under normal driving conditions, so you can keep the ECO mode on continuously. The main principle of ECO mode is not complicated. It involves a comprehensive analysis and judgment of factors affecting fuel consumption during driving, such as automatic transmission gear position, engine speed, vehicle speed, braking, and transmission oil temperature. The ECU control unit calculates the optimal fuel quantity to supply the engine, effectively reducing fuel consumption compared to normal driving modes. Simply put, it controls the engine speed with appropriate gear shifts to minimize unnecessary fuel consumption. ECO is an abbreviation, with its Chinese translation representing Ecology (environmental protection), Conservation (energy saving), and Optimization (power). 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 means the vehicle's economy mode is activated. ECO mode can be 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 enable it. When the driver presses the ECO mode switch, the dashboard indicator lights up, and the vehicle automatically adjusts settings such as throttle opening, transmission shift logic, and air conditioning output power. Passive ECO mode does not have a dedicated button. When the ECO indicator on the dashboard lights up, it serves as a reminder function. ECO automatically evaluates your driving behavior. If your current driving operation achieves the optimal fuel supply, the dashboard will display the ECO indicator. Most cars adopt the active ECO driving mode, meaning they have a dedicated switch button. Therefore, during daily driving, you can enable ECO mode. However, it is unnecessary to activate 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 may not reflect the fuel-saving characteristics of ECO mode and could affect performance. Additionally, ECO mode typically becomes ineffective under the following conditions: When the vehicle speed exceeds 120 km/h, the system prioritizes speed, causing ECO mode to deactivate automatically. During idle parking or when in N/P gear or manual mode, ECO mode may also become ineffective. When high torque output is required, such as when climbing hills, the engine control unit prioritizes providing sufficient power to drive the vehicle, and ECO mode will not function.
