It needs to be cleaned. Depending on the usage environment, it generally needs to be cleaned once every three years. The following is a relevant introduction to the function of car air conditioning: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state, providing a comfortable riding environment for passengers, reducing travel fatigue, creating good working conditions for the driver, and playing an important role in ensuring safe driving as a ventilation device. Composition: The modern air conditioning system consists of a refrigeration system, heating system, ventilation and air purification device, and control system. Layout form: The layout form is to assemble the evaporator, heater radiator, centrifugal blower, control mechanism, etc., together, which is called the air conditioning unit assembly.

As a veteran driver with over a decade of experience, I can't stress enough how crucial evaporator cleaning is. This component in the AC system is responsible for cooling the air, but due to its damp environment, it easily accumulates dust and bacteria, eventually developing mold and unpleasant odors with prolonged use. If left uncleaned, those contaminants get blown into the cabin when you turn on the AC, potentially causing sneezing or discomfort, especially for people with respiratory issues. I recommend cleaning it annually or whenever odors appear - professional shops can thoroughly flush it with specialized cleaning agents, a quick and simple process. Neglecting cleaning may also clog drain pipes, reduce cooling efficiency, and weaken airflow. I learned this the hard way when my car became unbearably hot one summer. Spending a little on cleaning extends your AC's lifespan and ensures fresh, healthy air. DIY cleaning is possible but less thorough than professional service - don't cut corners on this maintenance essential.

Is the 15-inch wheel data of the new Jetta normal?

The 15-inch wheel data of the new Jetta is normal. The various parameters fit well with the original vehicle, and it is recommended to replace the tires with a specification of 205/50/16. Classification and advantages of wheels: Wheels can be divided into steel wheels and alloy wheels based on material, each with its own pros and cons. The main advantage of steel wheels is their simple manufacturing process (usually produced by casting, whereas aluminum alloy wheels are typically manufactured using low-pressure casting), relatively low cost, and strong resistance to metal fatigue. Precautions for wheel usage:

Does the vehicle owner need to be present to apply for ETC?

Non-owners can also apply for ETC. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Expressways" issued by the Ministry of Transport, the original valid ID card of the vehicle owner, the original and photocopy of the vehicle registration certificate (showing the most recent annual inspection stamp page) are required. For proxy applications, the original valid ID card of the proxy is also needed. If applying for ETC through major bank branches, a debit or credit card from the corresponding bank is required. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding with debit cards. ETC Deduction Principle: There will be one or more ETC lanes on highways. Through dedicated short-range microwave communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at toll stations, and using computer networking technology for backend settlement with banks, the system achieves the purpose of collecting tolls without requiring vehicles to stop at toll stations. All this is based on the principle of "pass first, deduct later". Benefits of Installing ETC: Time-saving: Eliminates the hassle of queuing and waiting; Green and eco-friendly: Low-carbon solution reduces noise and exhaust emissions by allowing vehicles to pass toll stations without stopping; Reduced wear: Saves costs by decreasing the frequency of vehicle starts and brakes, thus reducing wear and fuel consumption; Improved efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC faster, more advanced, and high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council explicitly 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 should be basically achieved, and the proportion of vehicles equipped with ETC should be significantly increased." It also set a target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles should reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, efforts will be made to promote ETC usage for trucks and explore deeper integration of ETC systems with smart transportation directions such as vehicle-to-vehicle communication and vehicle-road coordination. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of over 10 meters to prevent automatic sensing and payment for the front vehicle, especially if it has a faulty or no ETC device. The recognized speed for ETC lane passage is 20 km/h. Speeding may prevent reading vehicle device information and lead to deduction failures. Unauthorized removal or movement of the OBU device, or detachment/loosening of the ETC electronic tag, will render the tag invalid. It can be taken to the bank where the ETC card was issued or the highway service office for inspection. Non-deliberate loosening or detachment only requires reactivation. Insufficient balance on a debit card bound to ETC may cause deduction failures. Follow on-site staff guidance to use manual MTC lanes and pay via cash or card. Excessively thick windshields may cause poor sensing. This is particularly relevant for vehicles that have had windshield replacements after accidents or modifications.

What is the tire size of the Toyota Levin?

Toyota Levin's tire size is 205/55-R16. Below are the specific details about the Toyota Levin's tires: 1. As one of the most important components of a car, Toyota Levin's tires are responsible for supporting the entire vehicle body and transmitting direction; they form good contact with the ground to ensure the vehicle can drive safely on the road. 2. When replacing tires, the specifications must match those of the original vehicle's tires. Wheels on the same axle should especially maintain consistent specifications, and the tread patterns and groove depths should be similar. For four-wheel-drive vehicles, it is best to replace all tires at once. If only two tires are replaced, it may result in inconsistent friction coefficients, leading to increased fuel consumption.
