The possible reasons for the dashboard not lighting up include: failure or damage of the dashboard illumination light; open circuit in the dashboard power supply wire; blown fuse of the dashboard power supply. Checking these aspects can help troubleshoot and resolve the issue. Here are some precautions: Regular maintenance of the dashboard: Avoid using rough or hard cloths or fingers to touch the dashboard casually to prevent fingerprints, scratches, and abrasions. It is advisable to prepare appropriate specialized cleaning supplies and perform regular maintenance on the dashboard. Applying an anti-scratch protective film: You can also try applying an anti-scratch protective film on the dashboard screen. There are various types of dashboard protective films available, and it is recommended to choose a static cling film without adhesive on the back. If the film is applied incorrectly, it can be removed and reapplied without causing any damage to the dashboard screen, and it can also prevent accidental scratches during future cleaning.

Once when I was driving to work, after starting the car, I found the dashboard completely dark, but the car could start and drive normally. It was quite scary, so I quickly pulled over to check. At first, I thought the dashboard fuse had blown. I opened the hood, located the fuse box, pulled out the corresponding small fuse, and sure enough, it had melted. Replacing it with a spare fuse solved the problem. Actually, besides fuses, loose wiring harness connectors for the dashboard are also common, especially after car washes when water can get in and oxidize the pins. Another possibility is a malfunction in the dashboard backlight circuit, which is particularly concerning when driving at night—without dashboard display, it affects checking speed and fuel levels. I recommend checking the fuse first; if that doesn’t solve it, take it to a professional shop to inspect the wiring, as it’s crucial for driving safety.

Can One Parking Space Be Registered for Two Cars?

Whether one parking space can be registered for two cars depends on the regulations of the residential property management. There are numerous property management companies in China, and there is no unified regulation on this matter. Some residential areas stipulate that one parking space corresponds to one card, allowing only one car to be registered. Other communities may allow each household to register multiple cars, but once one car scans its license plate to enter, other cars cannot enter; alternatively, if another vehicle wishes to enter, it may be charged as an external vehicle, and if there are no available parking spaces in the community, entry will still be denied. Below is relevant information: In most residential areas, a standard parking space can only accommodate one car. If multiple cars are parked in one space, it may occupy others' parking spaces, infringing on their legitimate rights and interests. Unless the owner purchases a large parking space capable of accommodating two small cars simultaneously, parking two cars must not harm public interests or others' legitimate rights.

What are the functions of each gear in a manual transmission?

Manual transmission: 1st gear for starting, 2nd gear for passing, 3rd gear for transition, 4th gear for driving, 5th gear for high speed, and R gear for reversing. Manual transmission cars: A manual transmission (MT), also known as a manual gearbox, requires the driver to manually shift gears by moving the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed variation. The working principle involves using shift forks to change the transmission ratio (gear ratio) of the engaged gears, thereby modifying the driving torque to suit different driving conditions. Automatic transmission cars: Since the transmission range is divided into several gear ratio segments, continuous variation is only possible within the specified segments. Therefore, an AT (automatic transmission) is actually a type of automatic transmission that lies between stepped and continuously variable transmissions. Pros and cons: AT does not require a clutch for shifting, has fewer gears with larger changes, and provides smooth connections, making it easier to operate. This not only brings convenience to the driver but also ensures comfort for passengers.

Can You Drive the Next Day After Drinking at Night?

After drinking one beer or half a liang of white liquor, it's best to wait 10 hours before driving. If you consume two bottles of beer or three liang of low-alcohol white liquor, it's advisable to wait a full day before driving. For higher alcohol content or larger quantities, an even longer waiting period is necessary before driving. Here are the relevant details: 1. Definition of drunk driving: Drunk driving is defined as when the driver's blood alcohol content (BAC) is 20 milligrams or more per 100 milliliters, but less than 80 milligrams. If the BAC reaches or exceeds 80 milligrams per 100 milliliters, it is classified as driving under severe intoxication. 2. Alcohol metabolism rate in the human body: Consuming one or two bottles of beer, approximately one liang of 12-degree red wine, or half a liang of 50-degree white liquor can reach the drunk driving standard. As for how long one should wait before driving after drinking, the metabolism rate of alcohol in the human body is limited, generally only 10 to 15 grams of alcohol per hour.
