Automotive metal film and regular film differ in the following ways: 1. Metal film: It interferes with imported GPS and ETC (Electronic Toll Collection) systems, causing GPS drift. It has a limited range for blocking infrared rays, typically around 1300 NM, offers average heat insulation, has a high reflectivity, fewer coatings, and does not oxidize. 2. Regular film: Regular automotive film is a dyed film that uses deep-dyeing techniques and adds heat-absorbing agents to absorb infrared rays from sunlight for heat insulation. However, since it also absorbs visible light, it results in insufficient visible light transmittance and poor clarity due to its inherent manufacturing limitations. Another major drawback of this type of film is that its heat insulation function degrades quickly, and it is prone to fading, though it is relatively cheaper in price.

Do I still need to collect the inspection exemption decal in 2021?

According to regulations, the annual inspection decal does not need to be applied for after the 2021 inspection exemption. Below is relevant information about inspection-exempt vehicles: 1. Inspection-exempt vehicles still require obtaining the inspection decal: Inspection exemption does not mean exemption from review. During the 6-year exemption period, every 2 years, you need to provide proof of compulsory traffic insurance, vehicle and vessel tax payment or exemption certificate to apply for the inspection decal from the traffic management department. 2. Meaning of inspection-exempt vehicles: The 6-year exemption for non-commercial passenger vehicles means the vehicle is exempt from on-site inspection, but you still need to go to a designated "6-year inspection-exempt vehicle" service point to obtain the inspection compliance decal.

What causes the key light to flash in the car?

The reasons for the key light flashing in the car are: 1. The car cannot detect the key; 2. The key battery is dead; 3. The key is not within the working range or placed in a hard-to-detect area inside the car; 4. The key was taken outside the car while the ignition switch was in the OFF position. During daily use, avoid remote controlling from long distances, as frequent long-distance remote control can affect the battery life, causing it to drain faster. Most cars equipped with a one-key start system can start the engine normally by placing the key at the inspection point when the key battery is dead. Vehicles with a one-key start system have a dedicated key inspection point inside the car, which is used when the key battery is dead.

Is It Okay to Only Replace Two Drive Wheels with Snow Tires?

Snow tires should not be installed on only two drive wheels. The principles and explanations of snow tires are as follows: Principles of Snow Tires: The tread that contacts the road surface uses a special silica-based compound to ensure the tire remains exceptionally soft even at extremely low temperatures, providing excellent grip on ice. The tread pattern typically employs a cross-Z siping technology, which not only enhances braking performance on snow and ice, shortens braking distances, but also delivers ideal traction. Explanation of Snow Tires: These tires are designed for use in snowy conditions, featuring rubber with metal studs to increase grip. In colder regions prone to snow accumulation, such as Russia, people use these tires during winter.
