The reason for one side of the car air conditioning vent being cool and the other side not is due to a damaged servo motor in the air duct. When encountering such a situation, it is necessary to go to a 4S shop or a professional institution for inspection and repair. The car air conditioning is an important comfort feature in a vehicle, capable of both cooling and heating, and is essential for use during both winter and summer. When the car air conditioning is cooling, the compressor clutch engages, and the engine drives the compressor to operate. During operation, the compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, thereby cooling the evaporator.

How many more kilometers can an Audi A6 drive after the brake pad warning light comes on?

Audi A6 brake pad warning indicates that the brake pads have worn to the manufacturer's preset wear limit. After the warning, the brake pads typically have 2 to 4mm thickness remaining and can theoretically drive about 1000 kilometers. When the brake pads are completely worn out, metal-on-metal contact occurs, which can groove the brake discs and increase safety hazards. Therefore, after the brake warning, you should inspect and replace them as soon as possible. Below are the signs of completely worn brake pads: Squeaking noise when lightly braking: If there is a metal-on-metal squeaking noise when lightly braking, the brake pads must be replaced immediately. This is because the wear indicators on both sides of the brake pads are already directly rubbing against the brake discs, indicating the pads have exceeded their limit. Difficulty braking: If braking feels very difficult, it means the brake pads have basically lost their friction and must be replaced immediately to prevent serious accidents.

Can non-vehicle owners apply for ETC?

Non-vehicle owners can also apply for ETC. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Highways" issued by the Ministry of Transport, the original valid ID card of the vehicle owner, the original and copy of the vehicle registration certificate, and the page with the latest annual inspection stamp on the registration certificate are required. If applying on behalf of others, the original valid ID card of the agent is also required. If applying for ETC through major bank branches, a debit card or credit card from the corresponding bank must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a certain amount as a deposit when binding ETC with a debit card. The principle of ETC deduction: There will be one or more ETC lanes on the highway. Through dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology for backend settlement with the bank, the vehicle can pay the toll without stopping at the toll station. All this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions, and minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also set a target in the main indicators of the "13th Five-Year" comprehensive transportation development: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When encountering a stopped vehicle ahead, to prevent the ETC device of the preceding vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters to avoid automatically sensing and paying for the preceding vehicle. The recognition speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, leading to deduction failure. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was issued or the highway service office for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also cause deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Excessive thickness of the car windshield can cause poor sensing. This is especially important for vehicles that have had their windshields replaced after accidents or for those who have modified their front windshields.

Is it necessary to install a 360° panoramic camera?

360° panoramic cameras are essential for drivers with limited driving skills, while they are optional for experienced drivers. The 360° panoramic monitoring system utilizes four wide-angle cameras positioned at the front, sides, and rear of the vehicle to monitor the surrounding conditions, providing the driver with a 360° panoramic view to eliminate all blind spots. Here are the functions of the 360° panoramic camera: After installing a 360° panoramic camera dashcam, the owner can intuitively view the surrounding environment of the vehicle through the original car screen. By performing normal driving operations such as shifting into reverse gear, turning on the turn signal, or using the turn lever, the view can be freely switched, enhancing driving safety.
