First, use the key to open the trunk. Check the location of the fuel tank cap. If it's on the right side, there will be a decorative cover panel on the right side of the trunk. Use a tool to open the decorative cover panel, and you will see a red emergency release device. Pull the emergency release device to open the fuel tank cap. You can hold the switch of the fuel tank cap and pull the fuel filler neck to test if it can open. If it opens, the pop-up mechanism is faulty; if it doesn't open, the issue lies with the cable mechanism.

I've been driving my Beidou Star for several years, and the issue of the fuel tank cap not opening is quite common, usually caused by dust accumulation or a stuck aging spring. You can first try gently pressing the edges of the cap and prying it open with a bit of force, but avoid using overly hard tools to prevent scratching the car paint. If that doesn't work, spray some lubricant like WD-40 into the gap, wait a few minutes, and try again. Remember to clean the fuel tank opening during refueling to prevent oil stains and dirt buildup, which can extend the cap's lifespan. If this happens frequently, consider replacing a small spring or part, as buying parts online is cheap. Additionally, a fuel tank cap that doesn't pop open can affect refueling efficiency, potentially preventing the pump from filling completely, wasting money and time. Addressing it early is much safer.

As a seasoned long-distance driver, don't panic when encountering a stuck fuel tank cap—it might be due to thin ice in winter or accumulated dust in summer. Manually check around the cap, remove any debris, and gently push to open it. Alternatively, wait until the car cools down before trying again. If it still won't budge, avoid forcing it, as this can damage the spring or latch. While this issue might seem minor, a poorly sealed cap can lead to fuel leaks or water ingress, affecting fuel efficiency—safety first. Here's a tip: Regularly clean the fuel tank area after parking and keep it dry to minimize malfunctions. Periodic lubrication of the hinges is key—I do it every six months, and it's hassle-free.

Are U-turn Markings at Traffic Lights Controlled by the Signals?

If the gap is marked with a dashed line, the U-turn is not affected by the traffic signal and does not require crossing the pedestrian crossing. You can make a U-turn directly, provided it does not interfere with other normally moving vehicles and ensures your own safety. If the gap is marked with a solid line, then the U-turn must cross the pedestrian crossing and is subject to the traffic signal. When making a U-turn that requires crossing the pedestrian crossing, you must yield to pedestrians: Pedestrians walking on the right side of the road's crosswalk, not reaching the centerline of the road. Vehicles on the left side of the road should slow down and proceed cautiously, ensuring safety while allowing pedestrians to cross. Pedestrians waiting outside the boundary line of the motorized and non-motorized lanes. If they have not entered the roadway, vehicles should slow down and proceed cautiously, ensuring safety while allowing them to cross. If pedestrians cross the dividing line between motorized and non-motorized lanes, vehicles failing to stop and yield constitute a violation and should be penalized. When pedestrians enter the motorized lane (Lane A) via the crosswalk, vehicles in Lane B should slow down and proceed cautiously, ensuring safety while allowing them to cross. If vehicles in Lane A do not stop and yield, it constitutes a violation and should be penalized. Pedestrians waiting at the centerline of the road without entering the motorized lane. Vehicles failing to stop and yield constitute a violation and should be penalized. Pedestrians crossing the centerline into the motorized lane. Vehicles failing to stop and yield constitute a violation and should be penalized. If the road is divided by a median with greenery, pedestrians waiting in the median area require vehicles to slow down and proceed cautiously, ensuring safety while allowing them to cross. Permissible U-turn scenarios: Intersections with U-turn signs allow U-turns: If there is a clear U-turn sign at the intersection, you can make a U-turn. If there is a U-turn signal light, follow its instructions. If there is no signal light, proceed based on the situation, ensuring no interference with other vehicles or pedestrians. Intersections without explicit 'No U-turn' or 'No Left Turn' signs allow U-turns: If there are no explicit prohibitions, U-turns are permitted. 'No explicit prohibition' means the absence of 'No U-turn' or 'No Left Turn' signs and no solid centerline, allowing confident U-turns. Yellow grid lines also permit U-turns: Yellow grid lines indicate no-stopping zones at intersections prone to congestion, important entrances, or other designated areas. Stopping on these lines (including waiting for traffic signals) is a violation. While stopping is prohibited, U-turns are allowed in these zones unless there is a central barrier. Yellow grid lines without central barriers equate to 'U-turn permitted.' Intersections with U-turn signal lights: If a U-turn signal light is present, follow it—U-turns are allowed only on green. Simultaneous 'No Left Turn' and 'U-turn Permitted' signs: U-turns are allowed, but left turns are prohibited. Note that 'No U-turn' is not the same as 'No Left Turn.' Precautions when making U-turns at intersections: Check road markings: If solid lines are present, U-turns are prohibited under any circumstances. Continue driving to find a suitable U-turn location. If a 'No Left Turn' sign is present, even without a 'No U-turn' sign, U-turns are not allowed at that intersection, as U-turns inherently involve left turns. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, U-turns are not permitted at that intersection. Always yield to straight-moving vehicles before making a U-turn. Proceed only if it does not interfere with their movement; otherwise, you bear full liability for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow. If it shows a straight arrow, U-turns are prohibited even without explicit 'No U-turn' signs.

What does TDI stand for?

TDI stands for Turbocharged Direct Injection. Many turbocharged engines and naturally aspirated engines are equipped with direct injection technology. In engines with direct injection technology, the fuel injector is located inside the cylinder. This injection method allows for more thorough atomization of gasoline, ensuring better mixing with air. However, most direct injection engines have a drawback: they are prone to carbon buildup, especially on the valves and in the combustion chamber. Therefore, it is recommended that owners of vehicles with direct injection engines regularly clean the carbon deposits inside the engine. For carbon removal, the walnut shell blasting method is suggested, as it is quite effective.

Why Concept Cars Are Not Mass-Produced?

Reasons why concept cars are not mass-produced: 1. Excessive technical requirements. Concept cars integrate cool appearances and intelligent high-tech configurations, reflecting automakers' visions and expectations for the future development trends of automobiles. Achieving these is not an overnight task. 2. Difficulty in passing tests. Many concept cars are only for display purposes and lack practical functionality. 3. Solely for showcasing brand philosophy. Automakers introduce concept cars primarily to convey their car-making philosophies, often without actual production. By presenting perfect craftsmanship to consumers, automakers create a favorable impression of the models, which helps enhance brand image.

How Often Should the Roller Weights Be Replaced?

There is no specific replacement interval for roller weights, as it depends on the actual usage conditions. Below are detailed explanations about roller weights: 1. Impact of Weight: Heavier roller weights generate greater centrifugal force, which shortens the vehicle's acceleration time. However, this can place excessive instantaneous torque on the crankshaft, potentially leading to crankshaft fracture in severe cases. Lighter roller weights produce less centrifugal force, resulting in slower acceleration from a standstill. 2. Replacement Based on Actual Conditions: Roller weights must be replaced according to actual conditions, and one should not overly pursue the thrill of rapid acceleration.

What music formats can be played by a car USB drive?

Car USB drives generally support music formats such as MP3 and WMA. Here are some precautions for using a car USB drive: 1. Format: Normally, vehicles can only recognize music files in MP3 or WMA format. When downloading music, pay attention to the file format. If the format is incorrect, it needs to be converted to MP3 or WMA. 2. Path: Try to place the music files in the root directory of the car USB drive. If the files are placed too deep, the car system may not be able to locate them. 3. Capacity: Some car systems may not support USB drives with excessively large capacities. Since car USB drives are mainly used for storing music, which does not take up much space, it is sufficient to choose an appropriate-sized USB drive, and there is no need to deliberately pursue large capacity.
