The 3C certification for glass is part of China's compulsory product certification system, serving as a fundamental safety certification. Methods for maintaining automotive windshield glass include: 1. Using specialized or appropriate wiper blades and replacing them promptly; 2. Keeping the glass surface clean; 3. Using automotive-specific glass cleaner. The functions of automotive glass are: 1. Protecting against wind and rain while reducing noise; 2. Minimizing wind resistance and improving airflow; 3. Ensuring the safety of vehicle occupants. The steps for adding windshield washer fluid are: 1. Activate the wiper switch, causing the washer fluid to spray from below the windshield; 2. Continue until the spray nozzles stop emitting fluid, then open the washer fluid reservoir cap and add fluid; 3. Reactivate the wiper switch to clear any remaining fluid; 4. Once no more fluid sprays out, add washer fluid and securely close the reservoir cap.

The 3C mark on the glass is actually the symbol of China Compulsory Certification. As an experienced driver with years behind the wheel, I place great importance on this. It certifies that the glass meets national safety standards, having undergone rigorous testing to ensure it won't cause injury when shattered in accidents and that its light transmittance meets requirements without affecting visibility. Without it, the glass might be made from substandard materials – seemingly fine for daily driving but dangerously fragile upon impact, with flying shards posing serious safety risks. I remember once helping a friend inspect a used car and noticing the absence of the 3C mark on the glass. Despite my advice against buying it, he went for the cheaper option, only to regret it deeply when a minor rear-end collision caused the glass to shatter and cut his hand. That's why I always check for this clear marking in the corners when buying a car or replacing glass – it's not just about compliance, but a matter of life responsibility. On the road, safety lies in the details; never overlook this small certification mark, as it brings both peace of mind and protection.

As someone who enjoys shopping for car accessories or buying new cars, the 3C mark on the glass is a must-check for me. As a budget-conscious ordinary car owner, I know this is China's official quality certification, meaning the product has passed testing and is qualified—substandard products are not allowed on the market. Although choosing glass with the mark might cost a few extra bucks, it saves money and ensures safety in the long run because it's durable and less prone to damage. It also affects the vehicle's warranty—for example, 4S shops may refuse repairs if uncertified glass causes issues. Some unscrupulous merchants in the market cut costs with counterfeit products, so carefully inspecting the mark before buying is a basic habit. Based on my experience helping a colleague choose glass, the 3C-certified one lasted years without issues, while the cheaper one cracked quickly. I recommend prioritizing quality—don’t let small things lead to big troubles.

What does the triangle exclamation mark indicate when the car is in reverse gear?

A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. Solution: It is necessary to visit a 4S shop for inspection to identify the source of the fault. The exclamation mark is a common fault indicator in cars. Besides the triangle with an exclamation mark, there are four other forms of exclamation marks: a yellow gear with an exclamation mark inside, a red circle with parentheses and an exclamation mark in the middle, a yellow bracket with a horizontal line and an exclamation mark in the middle, and a yellow bulb with an exclamation mark. Below is a detailed analysis of these four situations: Automatic transmission failure: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant below the normal range. It is necessary to replace the transmission oil promptly. Brake system failure: A circle with parentheses and an exclamation mark in the middle represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire pressure abnormality: A bracket with a horizontal line and an exclamation mark in the middle represents the tire pressure monitoring warning light, which illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting failure: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling a malfunction in the vehicle's lights. Solution: Visit a 4S shop for inspection and repair as soon as possible, or perform a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue.

Where is Haojue Wang Dawei from?

Haojue Wang Dawei is from Luoyang. Below is an introduction to motorcycle-related content: Working Principle: When the pedal is pressed, the mechanism pressurizes the spring, causing the outer edge of the spring to lift and the friction lining to separate from the friction plate. At this point, the friction plate and the flywheel can no longer engage, meaning that even if the engine continues to run, power will not be transmitted to the gearbox and wheels. This allows the driver to perform actions such as shifting gears or stopping the vehicle without causing the engine to stall. Power Transmission: When the crankshaft rotates at low speeds, the two friction linings do not contact the outer casing, preventing power transmission. At higher crankshaft speeds, centrifugal force causes the friction linings to move outward and engage with the outer casing, enabling power to be transmitted.

What is the reason for successfully reversing into the parking space in one go?

During the initial process of fully turning the steering wheel, it is necessary to observe the distance relationship between the car body and the corner of the parking space in the rearview mirror. When this distance is about 30 centimeters (mirror system distance of two fingers' width), and the angle between the car body and the parking line is approximately 45 degrees, it is the best condition for successfully reversing in one go. Reversing distance: If this distance is too narrow or too wide, it needs to be adjusted to achieve the ideal distance for one-go reversing. If the distance is too narrow, it indicates that the steering was turned too early, slightly less than 30 centimeters. In this case, you can first turn the steering wheel back two turns. However, if you are about to hit the corner of the parking space, you must immediately steer to the right to avoid it, and only after creating enough distance can you turn the steering wheel back. Timing for steering adjustment: If the distance is too wide, it means the steering was turned too late. When reversing into the parking space, you need to delay the timing of steering adjustment, allowing the car body to enter the parking space at an angle. Once a sufficiently large distance is created, you can steer to the right to adjust and straighten the car body.
