What is the purpose of the barcode sticker on a new car's windshield?

The barcode sticker on a new car's windshield is used by the production plant for scanning purposes. Once scanned, the information is recorded in the computer system and becomes unnecessary after the vehicle leaves the factory. Here are some maintenance tips for car glass: Proper use of windshield washer fluid: There are various types of windshield washer fluids available on the market, mainly categorized into three types: summer-use windshield fluid, winter antifreeze windshield fluid, and special antifreeze windshield fluid. Summer-use windshield fluid is primarily used to remove insect residues from the glass surface, while winter antifreeze windshield fluid ensures that car components are not damaged when temperatures drop below -20°C. Applying window film: A thin layer of heat-insulating film can make a significant difference, not only blocking the intense sunlight but also providing heat insulation and UV protection. Car heat-insulating films are divided into front and rear windshield films and side window films. It is particularly important to avoid dark-tinted heat-insulating films on the front windshield. When selecting a heat-insulating film, the higher the UV protection index, the better, as it helps protect dashboard components from premature aging due to prolonged sun exposure. Purchasing glass insurance: This is a type of commercial insurance where the insurance company is responsible for compensating the insured vehicle for losses incurred due to the breakage of its glass during use. Glass breakage refers specifically to situations where only the windshield or window glass of the insured vehicle is damaged.

How to accurately check the car's engine oil?

Keep the car stationary for about 5 minutes; otherwise, the oil may not have fully flowed back to the oil pan, leading to an inaccurate check. Pull out the yellow oil dipstick, wipe it clean with a tissue, reinsert it, and then pull it out again to check. Typically, the dipstick has markings or scales divided into three sections, with the ideal oil level being between the upper and lower limits. Some cars are equipped with an electronic oil dipstick, making it easier to check. Checking the oil dipstick is simple: park the car on level ground, turn off the engine, wait for at least an hour, then pull out the dipstick to check the oil level. Generally, when the engine is cold, the oil level should be above 3/4 of the range between the upper and lower marks; when the engine is warm, the oil level should be above 1/2 of this range, indicating sufficient oil. Typically, checking once a week is sufficient. After the engine is turned off, the oil flows back into the oil reservoir from various parts, and the dipstick reading at this time is the normal value. After an oil change during maintenance, the oil filter is usually replaced as well. In this case, start the engine and let it idle for a few minutes before turning it off and checking the oil level when the engine is cold. This is because the new oil filter will fill with oil after the engine is started, causing a slight drop in the oil reservoir level. The dipstick reading may differ by about 2-3 mm from before the oil was filled.

What is the difference between National IV and National V?

The differences between National IV and National V are: 1. Different upper limits for sulfur content in gasoline: National IV stipulates an upper limit of 50 milligrams per kilogram for sulfur content in gasoline; National V stipulates an upper limit of 10 milligrams per kilogram. 2. Different nitrogen oxide emission standards: The nitrogen oxide emission standard for National IV is 0.08 milligrams per cubic meter; for National V, it is 0.06 milligrams per cubic meter. The methods to distinguish between National IV and National V are: 1. Check the vehicle fuel consumption label; 2. Check the vehicle nameplate; 3. Check the environmental inspection compliance mark. National IV and National V refer to different stages of emission standards stipulated by the state. The higher the number of the emission standard, the higher the level, and the higher the level, the lower the engine emissions will be.

Can a Car Refrigerator Be Used at Home?

Car refrigerators can indeed be used at home. Most car refrigerators currently on the market are designed for dual-purpose use in both cars and homes, and come equipped with car power cords and home power cords or home voltage converters. Here is some relevant information: Classification of car refrigerators: Car refrigerators are divided into two main categories: thermoelectric (semiconductor) and compressor types. Compressor car refrigerators: Among these, compressor car refrigerators are the most suitable for home use. They employ traditional refrigerator technology, offering advantages such as large capacity and high cooling efficiency. However, they also have the drawback of being less portable when used in cars. Thermoelectric (semiconductor) car refrigerators: On the other hand, thermoelectric car refrigerators are compact, capable of both cooling and heating, pollution-free, environmentally friendly, and easy to carry. However, since they do not use refrigerant for cooling, their cooling efficiency is low, and the cooling effect can be affected by environmental conditions. For example, when the ambient temperature is 30 degrees Celsius, the car refrigerator can only cool to 5-10 degrees Celsius and cannot achieve freezing.

Can You Drive When the Car Dashboard Indicates an Oil Change?

You should not drive when the car dashboard indicates an oil change, as continued driving may cause mechanical damage. The steps to change the car oil are: 1. Start the vehicle's engine to warm it up; 2. Loosen the oil drain bolt; 3. Remove the oil filter; 4. Apply new oil to the gasket of the new oil filter; 5. Pour the new oil into the oil pan; 6. Check for leaks under the engine, inspect the oil dipstick, and start the engine for testing. Precautions for changing the oil include: 1. Perform the oil change when the engine is warm to ensure the old oil is drained as completely as possible; 2. Add the new oil and ensure the correct amount is used; 3. After adding the oil, start the engine and check all components for any leaks.
