The yellowing and aging of dashboard plastic can be cleaned by using a soft cloth with specialized cleaning and care agents. Below is relevant information about the dashboard: 1. Cleaning: If a specialized cleaning and care agent is not available, toothpaste can be used as an alternative. However, long-term use of toothpaste on transparent plastic surfaces may cause the dashboard surface to become blurry. The plastic dashboard cover is generally a replaceable part, available at most repair shops at an affordable price, possibly even cheaper than specialized cleaning agents. If the plastic dashboard cover turns yellow and becomes unclear, it is recommended to replace it directly for a more cost-effective and convenient solution. 2. Protection: There are currently water-based products specifically designed for use on automotive interior plastic parts such as dashboards, door trim panels, and pedals. These products provide gentle care, effectively removing dirt from plastic parts, killing bacteria, and decomposing oxygen free radicals, thoroughly improving dullness and restoring the original color of the plastic parts. Plastic crystal coating is a high-hardness, glass-fiber coating agent that repairs whitening of plastic parts and prevents "re-whitening" for a certain period. It offers long-term protection, restores the original luster of plastic parts, and adds an external protective layer to make the restored luster more durable and the effect more significant.

I have plenty of experience with this issue. Just last week, I helped a neighbor deal with a yellowing dashboard—plastic oxidation is the main culprit. For minor yellowing, you can use a specialized plastic restorer paste; apply it, wait ten minutes, then polish for instant results. If the dashboard becomes sticky or brittle, it's more serious and requires replacement. Daily prevention is actually more important: use a sunshade when parking and apply dashboard protectant monthly. I've seen people try home remedies like wiping with essential oils—definitely don't do that! It can corrode the plastic. If you're handy, you can buy a dashboard sunshade mat for a few bucks to solve sun exposure issues, but be aware it might interfere with airbag deployment, so choose a professional-grade option.

Is a Paper Inspection Exemption Label Still Required with the Electronic Version?

Currently, the paper inspection exemption label still needs to be affixed for the following reasons: During the promotion phase: The electronic inspection exemption label is being widely promoted but has not yet been fully implemented in all regions. Many areas still require the display of a paper inspection exemption label. Starting from March 2020, many cities began implementing electronic vehicle inspection qualification labels, eliminating the need for paper stickers. However, this does not mean that all regions no longer require the display of annual inspection labels. Some areas have not explicitly stated that vehicle inspection labels do not need to be affixed. Therefore, vehicle owners are still required to affix the annual inspection label in the designated location. Vehicles that fail to comply with the regulations or do not display the annual inspection label will be penalized according to the law. Penalties for non-compliance: In regions where electronic inspection labels have been implemented, paper inspection labels may not need to be affixed. If stopped by traffic police, presenting the electronic inspection label will suffice. However, the specific enforcement situation should be confirmed with the local traffic management authorities. Hence, vehicle owners are still advised to affix the annual inspection label in the designated location. Vehicles that fail to comply with the regulations or do not display the annual inspection label will be penalized according to the law.

What is the reason for the loud clicking sound when the car window is rolled up to the top?

The reason for the loud clicking sound when the car window is rolled up to the top is due to dust accumulation in the window rubber guide channel; aging of the rubber in the window glass guide channel. Below is relevant information about automatic window closers: Introduction: A car window lifter refers to a device that automatically closes the windows for the owner when they forget to do so upon exiting the vehicle, also known as an automatic window lifter, to prevent forgetful owners from leaving their windows open, which could lead to car damage or theft. The window lifter is also known as a window closer, car automatic window closer, car window lifter, car automatic window lifter, etc. Function: This product adopts a user-friendly design, intelligently detects the original vehicle status, automatically checks whether the glass is fully raised, and employs a secondary detection mode. The window lifting system will close any windows that are not properly shut, ensuring property safety.

What is the difference between engine oil A3B4 and A5B5?

A5B5 differs from A3B4 in terms of thermal-oxidative stability, anti-wear properties, detergency, dispersancy, and viscosity retention. The difference between engine oil A5B5 and A3B4 is that A3B4 has better anti-wear performance than A5B5, but A5B5 has higher fuel economy requirements than A3B4. In lubricant certification, A5B5 surpasses all current API quality grades and is a full synthetic oil (PAO). A5B5 is one of the EU certification standards, where 'A' represents gasoline engines for passenger cars, 'B' represents diesel engines for passenger cars, and the numbers indicate the oil grade. A5B5 is the highest-grade lubricant, primarily designed for high-performance gasoline engines and light-duty diesel engines that use low-viscosity oil. It offers excellent cooling and lubrication properties and also performs well in environmental protection. A3B4 is the European automobile manufacturers' testing and certification standard for automotive lubricants. A3 refers to higher-grade products, equivalent to API-SL level. B4 refers to the highest-grade product, surpassing all API oil standards.

Can a B1 driver's license drive a B2 vehicle?

B1 driver's license cannot drive B2 vehicles. The other vehicle types permitted for B1 license holders are C1 (small cars), C2 (small automatic transmission cars), C3 (low-speed trucks), C4 (three-wheeled cars), and M (wheeled self-propelled machinery). It is important to note that B2 vehicles are not included in the permitted vehicle types for a B1 license. B2 driver's license vehicle types: The vehicles that can be driven with a B2 license are heavy-duty, medium-duty trucks or large, heavy, and medium-duty special-purpose vehicles. Heavy-duty and medium-duty trucks are mostly trucks, such as the large dump trucks commonly seen on the road, which belong to heavy-duty trucks. B2 is a truck vehicle type, which is completely different from the B1 medium-duty passenger vehicle type. If you want to drive B2 vehicles, you can take the test to upgrade to a B2 license. Age requirements for B2 license application: There are age restrictions to follow, with a minimum age of 20 and a maximum age of 50. You can only apply within this age range, and exceeding it will make you ineligible. The license can be used up to the age of 60. After the driver turns 60, the license must be downgraded to a C1 motor vehicle driver's license, and the driver must annually provide a physical condition certificate for motor vehicle drivers to the vehicle management office or the traffic management department of the public security authority.

Should I Use M+ or M- When Going Downhill?

Using the M+ gear when going downhill allows for full utilization of engine braking to reduce vehicle speed. In automatic transmission vehicles, there's no need to depress the clutch, and the engine won't stall. The M+ and M- are manual mode gears of an automatic transmission. After switching to manual mode, the driver can upshift or downshift using paddle shifters or the gear lever. However, unlike manual transmissions, there's no need to release the throttle when shifting gears; you can directly increase or decrease the gear. The following situations are suitable for using M gear: Overtaking: Using the "M-" gear to downshift provides higher torque, allowing the vehicle to accelerate quickly in a short time. Uphill: On uphill sections, "M-" should be used as lower gears deliver stronger engine power. Downhill: You can use "M+" to adjust the gear to 2-3, utilizing the engine's braking effect to slow the vehicle without relying entirely on the brakes, thereby enhancing driving safety. High-speed sections: On highways, drivers can manually use "M+" to shift to higher gears, maintaining speeds of 80-100km/h for better fuel efficiency. Snowy/icy roads: Adjusting to gear 2 using "M+" can reduce wheel slippage. Essentially, M gear puts vehicle control in the driver's hands, functioning merely as a mode. Some models don't have "M+" or "M-" but feature D1, D2, D3 gears which serve the same purpose.

How Often Should Brake Fluid and Transmission Fluid Be Replaced?

Brake fluid should generally be replaced every 50,000 kilometers, with a maximum interval of 60,000 kilometers or 3 years, whichever comes first. Exceeding these limits may cause the brake fluid to deteriorate, absorb moisture, or become contaminated, leading to reduced braking performance. Below is an extended explanation: Function of Brake Fluid: If you primarily drive at low speeds in the city and rarely on highways, you might not notice any issues even if the brake fluid is dirty. However, for those who frequently drive on highways or encounter situations requiring rapid or repeated braking, the braking force may noticeably diminish after multiple consecutive applications. Brake fluid serves to transmit force—it should neither be too thin nor too thick, as both conditions can affect braking efficiency. Most critically, it must not contain water, as moisture can vaporize when heated, creating air pockets. Since air is compressible, this can significantly impair braking performance.
