Brake light switch damage or transmission failure can cause the 4WD warning light to flash. 4WD light flashing: 4WD light flashing generally indicates a fault in the 4WD system, mostly caused by brake light switch damage, but it could also be due to transmission failure. Engine warning light flashing: This is mainly caused by the oxygen sensor monitoring an abnormal air-fuel ratio. If the short-term fuel trim correction coefficient remains too large or too small for a period of time, the long-term fuel trim correction coefficient will increase or decrease accordingly. This indicates that the ECU has been controlling the engine operation with an enriched or lean mixture for a period of time.

Does a BMW Run-Flat Tire Need to Be Replaced After Losing Pressure?

Tires are rubber products, and prolonged use can lead to aging. Tire selection: When purchasing tires, always check the specifications and model, as well as the production date, speed rating, and load index. Most passenger car or SUV tires have "91V" marked on the side. After reinstalling tires, always perform wheel balancing to prevent abnormal vibrations at high speeds.

What is a Manual-Automatic Transmission?

Manual-automatic transmission, also known as manumatic transmission, combines both manual gear shifting and automatic gear shifting modes into one transmission system. With the manual gear selection mode, drivers can manually downshift to an appropriate gear before entering a curve, maintain the desired RPM during the curve, and have sufficient power when exiting the curve. Essentially, a manual-automatic transmission is still a type of automatic transmission that simulates the operation of a manual transmission through an electronic control system. Automatic transmissions significantly reduce the impact of manual shifting on the vehicle's drivetrain, thereby extending the vehicle's service life and improving ride comfort. Manual transmissions, lacking the hydraulic torque converter found in automatic transmissions, are generally more fuel-efficient.

What are the reasons for the inaccurate fuel gauge display on the Baojun 510?

The reasons for the inaccurate fuel gauge display on the Baojun 510 include: faulty fuel level sensor, clogged carbon canister, malfunctioning fuel gauge, etc. Fuel refill amount: Generally, filling until the pump automatically stops is sufficient. There is no need to manually add more to round up the amount. After refueling, remember to tighten the fuel cap until you hear a click before leaving. Checking the fuel gauge: Before driving, check the fuel gauge. Based on the distance of your trip and the fuel gauge reading, calculate whether you need to refuel during the journey. It is advisable to refuel in advance rather than waiting for the fuel warning light to come on. The fuel pump is located inside the fuel tank and operates at high temperatures when continuously working. Being submerged in fuel helps to cool it effectively. When the fuel warning light comes on, it indicates that the fuel level is below the fuel pump. If you always wait for the light to come on before refueling, it will shorten the lifespan of the fuel pump. Additionally, having too little fuel in the tank may even cause the fuel pump to burn out. Best time to refuel: It is better to refuel in the morning or evening, avoiding the midday when the sun is strong and temperatures are high. Gasoline is charged by volume rather than by weight, and it expands with heat and contracts with cold. Refueling in the morning or evening means that the same volume of gasoline will have a higher mass, saving you money.
