The original strength of the car A-pillar can hardly be guaranteed after cutting and welding, which affects the safety of the vehicle. The following is a detailed introduction to the car A-pillar: Function: The A-pillar protects the occupants from danger during a vehicle rollover and absorbs and disperses the impact force caused by a frontal collision. However, if the A-pillar is designed to be particularly thick, it will greatly increase the A-pillar blind spot for the driver. Therefore, the A-pillar should be reduced in size as much as possible under the premise of meeting sufficient strength to ensure sufficient visibility for the driver. Location: The A-pillar of a car is the pillar between the front windshield and the driver's side window glass; for large MPVs and SUVs, there is also a D-pillar in addition to the A-pillar, B-pillar, and C-pillar.

Are there discounts for using ETC on highways?

According to the relevant regulations of the State Council, ETC users receive a unified 5% discount on tolls. However, banks that handle ETC applications offer even greater discounts to encourage more people to apply. Starting from 2020, vehicles without ETC or not using ETC will not enjoy toll discounts. In the future, highway toll stations will retain only one manual lane, and vehicles can only pay tolls through manual channels, with lower efficiency compared to ETC lanes. The principle of ETC toll deduction: 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, combined with computer networking technology for backend bank settlement, vehicles can pay tolls without stopping at toll stations. This is all 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, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions, thereby minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Users also enjoy a 5% discount on tolls; Improved efficiency: The efficiency of ETC lanes can theoretically increase by 2-3 times, making traditional ETC faster, more advanced, 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, intercity transportation cards will be widely used in key city clusters, and the proportion of vehicles equipped with ETC will significantly increase." It also set a target in the "13th Five-Year Plan" for comprehensive transportation development: "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 use for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for car owners, meaning more application scenarios will support ETC. ETC usage precautions: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of at least 10 meters to prevent automatic sensing from deducting tolls for the wrong vehicle, especially if the front vehicle has a faulty or no ETC device. The recognized speed for ETC lane passage is 20 km/h. Driving too fast may prevent the system from reading the vehicle's device information, leading to toll deduction failure. Unauthorized removal or movement of the OBU device, or if the ETC electronic tag falls off or becomes loose, will render the tag invalid. It can be taken to the bank where the ETC card was issued or a highway service center for inspection. If the issue is not due to human interference, reactivation may suffice. When using a debit card linked to ETC, insufficient balance may cause toll deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pay with cash or a card. Thick windshields may cause poor signal reception. This is particularly important for vehicles that have had windshield replacements after accidents or for those who have modified their front windshields.

Can the Car Windshield Be Polished?

Minor scratches can be polished. Below are the relevant details: 1. Situations requiring polishing: When the glass surface is worn by small sand particles or severely scratched by wiper blades due to sand friction, causing the surface to become rough and transparency to deteriorate, regular cleaning will no longer solve the problem, and polishing treatment becomes necessary. 2. Precautions: During polishing, it is advisable to use high-precision equipment. Low-precision polishers may produce uneven surfaces under high-temperature grinding, and improper operation can lead to further damage to the glass.

Does the BMW 325 have wireless charging?

BMW 325 has wireless charging. Principle of wireless charging: Since energy is transmitted between the charger and the electrical device through a magnetic field, there is no need for a wired connection between the two. Therefore, both the charger and the electrical device can be designed without exposed conductive contacts. Introduction to charging methods: There is one USB port each in the front and rear rows. Wireless charging technology (Wireless-charging-technology; Wireless-charge-technology) originates from wireless power transmission technology. Low-power wireless charging often adopts electromagnetic induction (such as the Qi method for charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction).

How Many Kilometers for the Second Maintenance of a Sedan?

The second maintenance for a sedan is typically performed every 10,000 kilometers. The second maintenance is a service operation that primarily involves inspecting and adjusting a vehicle after it has been driven a certain mileage. The second maintenance includes inspection and maintenance of eight major systems: the engine, transmission, braking system, steering system, air conditioning system, body system, tire system, and suspension system, covering multiple items. Additionally, there is quality inspection and test driving. The key focus, similar to the first maintenance, is on replacing the engine oil and oil filter. Car maintenance, also known as vehicle servicing, refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car.

Can Car Seat Heating Blow Cold Air?

Car seat heating cannot blow cold air. Function of seat heating: Seat heating uses electric heating wires inside the seat to heat the interior and transfers the heat to the occupant through thermal conduction. The primary purpose of this design is to alleviate discomfort caused by the seat being too cold after prolonged parking during winter. Temperature adjustment for seat heating: To enhance passenger comfort, the seat heating temperature is controlled within a certain range by installing two temperature controllers in the heating pad. "Lo" is the lowest setting for seat heating, while "Hi" is the high setting. You can adjust the heating level according to your needs.
