Here are the five major functions of transmission fluid: 1. Cleaning effect: Keeps the shifting system clean. 2. Extending lifespan: Prolongs the service life of internal transmission components. 3. Low-temperature resistance: Provides effective lubrication even in cold conditions. 4. Reducing fluid loss: Minimizes fluid loss under harsh operating conditions. 5. Lubrication: Ensures the normal operation of the transmission. Note: Under normal driving conditions, automatic transmission fluid should typically be replaced every 120,000 kilometers, and every 60,000 kilometers under severe driving conditions.

What does the BMW 3 Series Eco Pro mode mean?

Eco Pro is the car's energy-saving driving mode. Eco is an English abbreviation formed by the combination of Ecology (environmental protection), Conservation (energy saving), and Optimization (power). The Eco mode is further divided into active Eco driving mode and non-active Eco driving mode. When the Eco indicator light on the dashboard lights up, it indicates that the car's economy mode has been activated. Eco mode is divided into active and non-active types. The difference is that the active type has its own button, allowing the driver to choose whether to activate it. When the driver presses the Eco mode switch, the dashboard indicator light immediately turns on, and the vehicle automatically begins adjusting settings such as throttle opening, transmission shift logic, and air conditioning output power. The non-active Eco mode does not have a dedicated button. When the Eco indicator light on the dashboard lights up, it is merely a reminder function. Eco 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 cars use the active Eco driving mode, meaning they have their own switch button. During daily driving, we can activate the Eco mode. However, it is unnecessary to enable Eco mode when the speed exceeds 120 km/h, during idle parking, in N/P gear, or in manual mode—especially when climbing hills. Doing so would not reflect the fuel-saving characteristics of Eco and could also impact the vehicle's power performance. Additionally, the Eco mode typically becomes ineffective under the following conditions: When the speed exceeds 120 km/h, the vehicle prioritizes speed, and the Eco mode automatically deactivates. During idle parking or 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 ensuring sufficient power to drive the vehicle, and the Eco mode will not function.
