a circle with an arrow around the letter 'a' represents the auto start-stop function. Here is some relevant information about the auto start-stop function: 1. Start on demand: After the car is started, the auto start-stop function enters the active mode. For example, when approaching a traffic light and stopping by pressing the brake for 1 to 2 seconds, this function will automatically turn off the engine. When the light turns green, simply lightly press the accelerator or turn the steering wheel to restart the engine. 2. Timely shutdown: In some manual cars, the computer determines when to shut down the engine based on actions such as pressing the clutch, shifting to neutral, and pulling the handbrake. The engine will restart when the clutch is pressed again.

Over the years I've been driving, that symbol with the letter 'A' inside a circle and an arrow around it is actually the auto start-stop system icon commonly found in modern cars. When you press this button on the center console or check the instrument panel, the light indicates the system is activated. It's quite clever: during red lights or traffic jams, the engine automatically shuts off to save fuel, then restarts when you press the accelerator, avoiding unnecessary fuel consumption. The technology relies on multiple sensors monitoring vehicle speed and engine status, combined with software controlling the engine's ignition timing. I've tried similar systems in different models like Toyota and Volkswagen, which can save about 10% fuel - quite economical for long-term use. Though some complain about slight vibrations during restart, you get used to it, and it's good for both the environment and your wallet. In short, don't panic when you see it - it's there to help you drive more economically.

What brand of engine does the Hongqi H9 use?

Hongqi H9's engine is produced by China FAW. This V6 engine, codenamed CA4GC20TD-31, is a domestically independently developed V6 engine. The CA4GC20TD-31 V6 engine is not equipped with a common turbocharger, but rather with a supercharger. This engine incorporates many technologies, such as a 200BAR fuel injection system. High-pressure fuel injection can effectively improve fuel atomization, thereby promoting gasoline combustion, which not only enhances power but also effectively reduces harmful emissions. During low-speed driving, the variable tumble technology can reduce the intake cross-section to lower emissions; during high-speed driving, it increases the intake cross-section to boost air intake. The engine consistently maintains excellent dynamic responsiveness. Coupled with the supercharger, it provides the engine with more efficient air intake, enhancing power while also improving fuel combustion quality.

What does EPC displayed on the vehicle dashboard mean?

The EPC indicator light has two illumination states: power-on self-test illumination and illumination under other circumstances. The power-on self-test is an indication that the vehicle monitors the status of all sensors before driving. Generally, if the vehicle is not started after power-on, the light will turn off by itself after about 3 seconds. In other cases, if the EPC indicator light remains on or does not turn off for a long time after the vehicle is started, the main reasons for the EPC indicator light staying on include faults in the engine intake system, throttle valve, fuel system, engine, ECU control unit, or brake lights. Below is a detailed introduction to the causes of the EPC light turning on under other circumstances: Engine intake system fault: The EPC light will prompt when the engine intake is not smooth or the intake volume is insufficient. Throttle valve fault: Carbon buildup is a common fault in the throttle valve. Additionally, dirt on the main body can also affect intake, causing the indicator light to turn on. Fuel system fault: For example, issues such as substandard fuel, fuel deterioration, or poor fuel atomization. Engine fault: Insufficient engine pressure or problems with the power system, such as the intake valve, can also trigger the EPC light. ECU control unit fault: For instance, interference with the vehicle computer signals or false alarms from the vehicle computer. Brake light fault: Situations like the brake light not turning on, brake switch failure, or brake circuit failure. Solutions for when the vehicle EPC indicator light turns on: Troubleshoot the intake system fault, use fuel with the appropriate octane rating, clean the throttle valve, etc. Remove carbon buildup from related parts. Re-flash the ECU-related data. If the EPC indicator light turns on, the owner can first try turning off the engine and restarting it to check if the EPC light remains on. If it does not turn on again, there may be no issue, possibly just the EPC indicator being affected. If the EPC indicator light remains on or frequently turns on, the vehicle should be driven to the nearest repair point for professional assistance in troubleshooting to eliminate potential safety hazards promptly. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system mainly includes controllers and sensors related to the power system. When the sensor data in the system is abnormal, the EPC system will take measures on the power system according to preset programs. Common EPC indicator lights are generally displayed in two colors: yellow and red. If the EPC fault light is yellow and the vehicle can still operate normally, drive slowly to a repair point for inspection. If the EPC fault light is red, it indicates a more serious situation. The vehicle should be pulled over immediately, and relevant repair personnel should be contacted for maintenance. Forcing the vehicle to drive under such conditions can directly affect the core components of the vehicle or driving safety.

What is the first maintenance mileage and time for FAW-Volkswagen?

Volkswagen's first maintenance should be done within one year or 7,500 kilometers. The first maintenance items include: Oil and oil filter replacement, battery inspection, brake pedal and parking brake inspection, brake pads and brake discs inspection, brake fluid inspection, clutch fluid inspection, tires and tire pressure inspection, lights, horn, wipers and washers inspection, and vehicle electronic system inspection. Engine oil selection for first maintenance: The official oil used for the first maintenance is Shell's semi-synthetic oil, with the oil model being 5W-40. Taking 0W-20 as an example: 0W in 0W-20 represents the cold start performance of the oil. Using oil with a lower number before W makes it easier to start the engine in cold weather. 20 in 0W-20 represents the viscosity characteristics of the oil at high temperatures. High-viscosity oil may be more suitable for high-speed driving or heavy-duty vehicles.

What causes the abnormal noise at the moment of starting a 2009 Highlander?

Reasons for abnormal noise at the moment of starting a 2009 Highlander: Engine mount rubber aging or loosening: The engine mount rubber is the rubber block placed between the engine and the vehicle frame. Its function is to reduce the vibration and buffering during engine operation and to secure the engine. Once the engine mount rubber ages or loosens, the engine will shake, and in severe cases, a "clicking" abnormal noise may occur. Excessively rich air-fuel mixture: When the engine's air-fuel mixture is too rich, the symptoms include difficulty accelerating after starting, uneven engine operation; black smoke from the exhaust pipe, accompanied by a clicking noise from the engine, sometimes backfiring; reduced engine power and increased fuel consumption. "Piston slap" abnormal noise: Due to poor lubrication conditions, excessive wear of the piston and cylinder wall leads to the clearance fit tolerance between the piston and cylinder wall exceeding the normal range. When the engine is running, the piston skirt impacts the cylinder wall, producing a crisp "clicking" sound, which is usually more noticeable at idle or low-speed operation.
