Methods to judge the distance by rearview mirror: 1. When the rear vehicle almost occupies the entire mirror, the distance is approximately 3m; 2. When the rear vehicle occupies about two-thirds of the mirror, the distance is approximately 5m; 3. When the rear vehicle occupies about half of the mirror, the distance is approximately 9m; 4. When the rear vehicle occupies about one-third of the mirror, the distance is approximately 12m. The rearview mirror is a tool that allows the driver, sitting in the driver's seat, to directly obtain external information about the rear, side, and lower parts of the car. For the convenience of the driver's operation, to prevent traffic safety accidents, and to ensure personal safety, it is mandatory for all vehicles to be equipped with rearview mirrors, and all rearview mirrors must be adjustable in direction.

What causes the B105200 fault code in the Baojun 510?

Baojun 510 reporting the B105200 fault code indicates an airbag detection malfunction. There are three scenarios when the airbag warning light illuminates: first, during vehicle self-check; second, due to wiring faults; third, because of airbag system malfunctions. When such a fault occurs, it is necessary to promptly read the fault code using a diagnostic tool. It is strongly advised not to attempt repairs personally. Instead, drive the vehicle to a 4S dealership for professional repair by qualified technicians to ensure safety. Airbag system composition: Mainly consists of the airbag, collision sensor, and electronic control unit (ECU). The driver-side collision airbag is installed in the steering wheel, while the passenger-side collision airbag is typically mounted on the dashboard. Airbag sensors are located on the left, right, and center of the cabin partition, with the central unit housing the airbag sensor, airbag system, and ECU. The airbag assembly primarily includes the airbag, gas generator, and ignition device. The ECU performs data collection and processing to diagnose airbag reliability, ensuring timely ignition signal transmission when preset thresholds are reached. This guarantees sufficient driving current for the gas generator with precise ignition timing.

Why is there no sound when playing music via Bluetooth connection between an Audi phone and the car?

Audi phone connected to the car's Bluetooth for playing music but no sound may be because only the hands-free calling is connected, and the Bluetooth media playback function is not enabled. The car's Bluetooth offers excellent features, providing numerous benefits. Functions of car Bluetooth: The main function is to use Bluetooth technology to connect with the phone for hands-free calls during normal driving, thereby freeing the hands and reducing the risk of traffic accidents. The car Bluetooth function automatically recognizes mobile phones without the need for cables or phone holders to connect with the phone; the owner can control the phone without touching it, even keeping both hands on the steering wheel, using voice commands to answer or make calls. Users can conduct calls through the car's audio system. Benefits of car Bluetooth: Besides freeing the owner from the hassle of manually answering calls and reducing the incidence of traffic safety accidents, Bluetooth has a very obvious health benefit. It eliminates the need to raise a hand and reduces the impact of electromagnetic radiation on the human body. This is because the electromagnetic radiation from Bluetooth is much lower than that from holding a phone directly to the ear.

What are the differences between the 2015 and 2016 Yuexiang V7 models?

There are differences in configuration and engine between the 2015 and 2016 Yuexiang V7 models. Configuration of both models: The V7 series lacks daytime running lights, tire pressure monitoring, and rear center headrests. Manual transmission models do not feature keyless entry/start, and the tires are from second-tier brands. In comparison, starting from the mid-range 560 model, it comes equipped with Continental tires, keyless entry/start, and standard daytime running lights, tire pressure monitoring, and rear center headrests. The 560 offers more features than the V7, though at a higher price point. Both models offer good value for money. Engines of both models: The Liuzhou-made 1.8L engine outperforms the previous General Motors 1.8L engine in terms of noise suppression and fuel efficiency. The 1.6L engine in the 2015 V7 appears to be part of Changan's self-developed BlueCore series, which is quite commendable among domestic brands. Both engines perform well in low-end torque for city driving, but their power reserves are just adequate, given their displacement. It's likely that the target users of both models do not have high demands in this aspect.

Is it better to buy a car in full or through financing?

Paying in full is more convenient and does not incur interest, making it a better option. Below are the differences between buying a car in full and through financing: 1. Financing: Apply for a car loan through auto finance companies, banks, or other institutions. With financing, you pay a down payment first and then repay the remaining amount monthly, gaining the right to use the car in advance. (1) Interest and fees: For a car with a total price of 100,000 yuan, the down payment is calculated at 30%. (2) Additional insurance: For financing, the commercial insurance part will be negotiated with the 4S store before purchase, at least including compulsory insurance, vehicle damage, third-party liability, and theft coverage. Discounts may be limited. (3) Renewal deposit: Some 4S stores require a renewal deposit, which will not be refunded if you do not renew the insurance with them the following year. (4) Vehicle certificate pledge: When financing, the 4S store usually holds the vehicle certificate as collateral, returning it only after the loan is fully repaid. 2. Full payment: Buying a car in full involves fewer complications, but with financing, many car dealers may add additional car accessories or decorations.
