In northern winters, it is generally recommended to use 0W30 grade engine oil, as the winters in northern China are relatively cold, and choosing a slightly lower viscosity is more suitable. The SAE lubricant viscosity classifications for winter oils are: 0W, 5W, 10W, 15W, 20W, and 25W. The symbol 'W' stands for winter, and the smaller the number before 'W,' the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable temperature. Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil's performance and impart certain new properties, making them an important part of the lubricant.

Can You Turn Right When the Red Light Is On?

Whether you can turn right when the red light is on depends on the actual situation of the traffic light. Generally, it can be divided into the following three scenarios: 1. No right-turn signal: If there are only left-turn and straight signals but no right-turn signal, you can turn right in this case. However, you must ensure safety and watch out for vehicles and pedestrians ahead. 2. Right-turn signal present: If the traffic light has a right-turn signal and it is red, you cannot turn right at this time. 3. Full red light: If it is a full red light without any additional auxiliary signs, you can turn right, but only after ensuring the safety of straight-moving vehicles and pedestrians.

What are the reasons for the limited automatic emergency braking function?

The automatic emergency braking function of the car may be limited due to poor wiring connections or issues with the millimeter-wave radar sensor. Poor wiring connections: Use a digital multimeter to check whether the circuit voltage is normal, and look for any loose connections or wiring issues. The wiring may need to be repaired. Radar sensor malfunction: Dirt on the radar sensor may cause false alarms. Check if the radar sensor is dirty, such as being blocked by mud, fluff, or similar debris, which can prevent it from accurately detecting the distance to obstacles ahead. This can result in the automatic emergency braking function being limited. You can use a tissue or cloth to clean it thoroughly.
