When passing under an arch bridge at night, alternate between high and low beams, using them no fewer than 2 times. Specific instructions are as follows: When driving at night and passing under an arch bridge or through an intersection without traffic lights, you should alternate between low and high beams. During this alternation, the switching between high and low beams should not be fewer than two times, ensuring that other vehicles can better notice your presence. Additionally, when passing through such intersections, it is necessary to reduce your speed, as this enhances driving safety. Relevant information is introduced as follows: When a motor vehicle passes through sharp curves, slopes, arch bridges, crosswalks, or intersections without traffic signal control at night, it should alternately use high and low beams to signal. When a motor vehicle approaches sections that affect safe visibility distance, such as sharp curves or the top of slopes, or when overtaking or encountering emergencies, it should slow down and sound the horn to signal.

I've been driving for decades, and crossing arched bridges at night requires extra caution. I use low beams steadily, which provide enough light to see the road clearly without dazzling others. The arch structure can suddenly darken your vision, and switching to high beams might reflect back dangerously. Generally, nighttime driving calls for more low-beam usage, maintaining a steady and moderate speed. Don’t neglect headlight maintenance—replace aging bulbs promptly, or you’ll feel more anxious in dark areas. In short, safe driving comes from accumulating small details; the responsibility lies in my hands to ensure smooth journeys every time. Choosing the right lights may seem simple, but it’s crucial—a little extra care reduces risks.

What does Dynamic mean on a Mercedes-Benz?

Dynamic on a Mercedes-Benz refers to the dynamic or sport mode. The dynamic (or sport) mode is equivalent to the S gear sport mode in other vehicle models. How to use the Mercedes-Benz dynamic button: It is located among the four buttons in the middle row of the center console, labeled E/S. Application scope of the car's sport mode: Used for climbing hills and overtaking. Precautions for the car's sport mode: In sport mode, the transmission load increases. Working principle of the car's sport mode: The transmission's shift timing will be delayed to maintain high engine RPM. Mercedes-Benz cars offer five driving modes to choose from: E mode: ECO economy mode; the most fuel-efficient, with a less responsive throttle, where initial pedal press has minimal effect, and the air conditioning system operates in the most energy-saving manner. C mode: Comfort mode; all settings prioritize comfort, with smooth power delivery and steering. S mode: Sport mode; more responsive power delivery, delayed shift timing, but the start-stop function remains enabled by default. S+ mode: Sport+ extreme sport mode; faster shift speeds, noticeable jerks at low speeds, and the start-stop function is disabled. I mode: Individual mode. Allows separate settings for power, steering, start-stop, and air conditioning to meet each driver's personal preferences. Application scope of the car's sport mode: Sport mode is more effective when climbing hills or overtaking. It can also be used during high-speed driving, and the high engine RPM in sport mode helps clear carbon deposits from the engine. Precautions for the car's sport mode: Do not keep the sport mode on continuously, as it increases the transmission load, raises temperatures, accelerates wear, and also affects fuel consumption. Working principle of the car's sport mode: In sport mode, the transmission's shift timing is delayed to maintain high engine RPM, thereby achieving greater torque output and improving the car's acceleration performance.

What to Do If a Gasoline Car Accidentally Adds a Small Amount of Diesel?

If a gasoline car is filled with diesel, to avoid engine damage, it is best to completely drain the fuel tank, clean it thoroughly, and then refill it with the appropriate oil for the vehicle. Here is some relevant information: 1. Research data shows that if the proportion of diesel added to gasoline does not exceed 5%, it generally does not cause significant damage to the engine. However, as the proportion of diesel increases, knocking and stalling can occur quickly, and in severe cases, it may lead to cylinder scoring. 2. The working conditions of gasoline engines differ from those of diesel engines. Gasoline has a lower ignition point, and gasoline cars typically ignite the air-fuel mixture via spark plugs, with lower cylinder pressure. Diesel engines, on the other hand, compress diesel fuel through high-pressure fuel pumps, injecting it into the cylinders via fuel injectors, resulting in higher cylinder pressure, rougher operation, and larger component clearances. Therefore, gasoline and diesel engines have different oil requirements. Gasoline engines require thinner oil with better fluidity, while diesel engines, which operate under higher pressure and harsher conditions, produce more carbon deposits and require thicker oil with stronger cleaning capabilities and larger clearances. Hence, gasoline cars should not use diesel engine oil.

Should You Check Engine Oil Level When the Engine is Cold or Hot?

Check the oil dipstick when the engine is cold, i.e., after the vehicle has been turned off for thirty minutes. This is because while driving, engine oil circulates throughout the engine to provide lubrication, reduce friction, dissipate heat, clean components, and perform other functions. When the vehicle is first turned off (hot engine state), the oil hasn't fully drained back, which can lead to measurement inaccuracies. Below is an extended explanation: 1. Cold vs. Hot Engine Oil Dipstick Variance. When oil hasn't fully drained back, the dipstick reading will show varying degrees of deviation depending on engine size and number of cylinders. Larger engines typically exhibit greater deviation. Generally, you should wait until the oil has completely drained back for an accurate dipstick reading. 2. Dipstick Standard Markings. The dipstick has upper and lower limit markings - the top marking indicates the minimum level (lower limit), while the bottom marking near the handle indicates the maximum level (upper limit). The oil level should normally be between these two marks. If the reading is at or below the lower limit, you should add oil appropriately. Engine oil is essentially the lifeblood of your engine, so regularly checking oil levels is a good driving habit.

How to Determine the Quality of Engine Oil?

You can determine the quality level of engine oil from the specifications on the oil packaging. Taking "0W-40 API SN/CF" as an example, the first part "0W40" is the main grade. The smaller the number before the "W," the better the low-temperature fluidity, which provides better engine protection. "0W" indicates that the oil can be used at temperatures as low as -35°C. The number "40" after the "W" represents the viscosity index of the oil at high temperatures. The higher the number, the higher the viscosity, which also means better engine protection. Here are methods to determine the quality of engine oil: 1. Listen to the engine sound after adding oil: If, after driving a few hundred kilometers, the engine sound becomes smoother and quieter, and the vibration stabilizes, it indicates good oil quality. Conversely, if the engine sound becomes louder, duller, or the vibration increases, the oil may be problematic. 2. Observe the color and smell of the oil: High-quality oil is light in color, transparent, free of impurities, suspended particles, or sediment, and flows well when shaken. The more transparent the oil, the higher its quality. Fake oil often has a pungent smell due to inferior raw materials or processes, while genuine oil does not. 3. Observe in low temperatures: Since engine oils vary in low-temperature performance, seal a small bottle of oil and place it in a freezer set to -18°C. After 6 hours, check its fluidity. High-quality oil will flow noticeably better, indicating better engine protection in cold conditions. 4. Shake and observe: Pour the oil into a bottle and shake it vigorously until many bubbles form. Then observe how quickly the bubbles disappear. Higher-grade, better-quality oil will see bubbles dissipate faster. If bubbles persist, the oil may be problematic. 5. Check fuel consumption after adding oil: Qualified oil, due to its superior lubrication, anti-wear, and cleaning properties, reduces friction in engine components, leading to better fuel efficiency. If fuel consumption increases significantly after adding new oil, the oil may be of poor quality.

How to Distinguish Whether a Vehicle is China III, China IV, or China V?

Methods to distinguish whether a vehicle is China III, China IV, or China V include: 1. The vehicle's factory certificate clearly indicates the standard; 2. Check the engine emission label; 3. The annual inspection label clearly indicates the standard; 4. Visit the Motor Vehicle Environmental Protection Website, enter the engine number and manufacturer name for new vehicle certification, and search for the vehicle's certification announcement, which explicitly states the emission standard. China III, China IV, and China V are common terms for China's various stages of vehicle emission standards. China III refers to the third stage of China's vehicle emission standards, which upgraded and modified the engine and exhaust system to reduce pollutant emissions, added vehicle self-diagnosis systems, and improved the three-way catalytic converter. China IV is the fourth stage of China's vehicle emission standards, which upgraded the post-emission treatment system compared to China III, reducing pollutant emissions by 50% to 60%. China V is the fifth stage of China's vehicle emission standards, imposing stricter limits on vehicle emissions such as nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter. Compared to China IV, the China V standard requires a 25% reduction in nitrogen oxide emissions and adds emission limits for non-methane hydrocarbons and PM, further reducing atmospheric pollution.

Should Automatic Transmission Cars Shift to Neutral at Traffic Lights?

Automatic transmission cars should shift to neutral when waiting at traffic lights, and using the handbrake will provide additional safety. More detailed information is as follows: 1. Waiting at traffic lights in D gear with the foot brake engaged causes the passive wheel in the torque converter between the engine and transmission to remain fixed, generating a reaction force on the driving wheel, which increases the engine load. This can be understood as hindering engine operation. As a result, the engine ECU increases fuel injection, leading to higher fuel consumption, which is why you can see a high instantaneous fuel consumption when braking to a stop. 2. It is not recommended to wait at traffic lights in P gear because shifting from P to D gear can sometimes cause the car to reverse, affecting the vehicle behind and potentially leading to a rear-end collision, for which you may also bear some responsibility. 3. Some vehicles now come with an "autohold" function, which is an automatic handbrake. After pressing the button to activate this function, the car will automatically brake once it comes to a stop, eliminating the need to shift between reverse and drive gears, and the vehicle will remain in a parked state. However, not shifting to neutral still poses certain safety risks, such as the car accelerating rapidly if the accelerator is mistakenly pressed, which could lead to a collision. Additionally, the auto start-stop function is also suitable for use at traffic lights, as it helps save fuel to some extent, and the engine, when turned off, does not emit exhaust fumes into the car.
