I just bought a BYD Qin PLUS not long ago, and as an ordinary car owner, I'm quite concerned about the battery warranty. Generally speaking, the battery warranty for Qin PLUS is 8 years or 160,000 kilometers, whichever comes first. This is quite crucial because repairing a PHEV battery if it ages or degrades can be expensive. I've checked the manual myself, and BYD promises to replace the battery free of charge if its capacity drops below 70%, provided it's under normal use without unauthorized modifications. Paying attention to daily driving habits, like avoiding prolonged storage with low battery and getting regular maintenance, can help extend the battery's lifespan. Honestly, the main appeal of buying an electric vehicle is peace of mind, and such a long warranty really eases my concerns, especially during long-distance drives or in cold northern winters when battery stability is even more important. If any issues arise, just take the warranty card to the 4S store—it's quite convenient.

What to Do When Your Car's Transmission Fails in Reality?

Here are the methods to handle car transmission failures in reality: 1. Transmission Slipping: Pull over and wait for rescue. Do not continue operating the vehicle to prevent further severe damage. 2. Transmission Jerking: Pull over and call for assistance. Do not continue operating the vehicle to prevent further severe damage. 3. Transmission Oil Leak: Visit a 4S shop for inspection and add transmission oil to ensure better lubrication for the transmission gears. 4. Transmission Noise: Contact the after-sales personnel at a 4S shop and follow their advice before taking any action. 5. Transmission Overheating: Park the car and let it rest for a few minutes. If the situation is severe, go to a 4S shop for inspection and repair.

What is the Transmission System?

The transmission system generally consists of components such as the clutch, gearbox, universal transmission device, main reducer, differential, and half-shaft. Its primary function is to transmit the power generated by the engine to the drive wheels of the vehicle, generating driving force that enables the car to move at a certain speed. Related introductions are as follows: 1. Intermediate Device: The transmission system is the intermediate device that transfers the power and motion from the power machine to the execution system, serving as the "bridge" connecting the power system and the execution system. There is a transmission connection between each execution component and the power machine in the execution system, and sometimes there is also a transmission connection between the execution mechanism and the execution component. 2. Transmission Chain: A series of transmission components that form the transmission connection is called a transmission chain. All transmission chains and their interconnections constitute the transmission system. There are numerous types of machinery with various uses. Therefore, the transmission systems of different machines vary greatly, but they typically include components such as speed change devices, start-stop and reversing devices, braking devices, and safety protection devices.

What car is SRS airbag?

SRS/Airbag is not a car model, but refers to the airbag, a well-known passive safety feature. Its official English name is SRS (Supplemental Restraint System), while it is commonly called Airbag based on its structure. Introduction to airbags: 1. Function: Airbags instantly deploy during vehicle collisions, using the inflated cushion to absorb impact and protect drivers and passengers. During crashes, the head and torso are most vulnerable, so airbag design prioritizes protecting these areas. 2. Service life: Automotive airbags have expiration dates because their inflators degrade over prolonged use. Airbag modules can only be replaced, not repaired. Although some aftermarket technicians claim to fix airbags, refurbished units may deviate from original specifications regarding interior panel weakening treatment and fragment dispersion angles during deployment.

What is the appropriate tire pressure in kPa?

Car tire pressure is normal within the range of 230-250 kPa. Here is more relevant information: 1. Tire pressure depends on the manufacturer: The normal tire pressure for a car should be based on the manufacturer's recommended value, which can generally be found in the vehicle's user manual, on the label near the driver's door (B-pillar), in the drawer next to the driver's seat, or on the small door of the fuel tank cap. These sources will provide detailed information on the specific tire pressure for use. 2. Factors affecting tire pressure: Tire pressure is also significantly influenced by seasonal factors. In summer, when temperatures are high, tires tend to heat up during driving. High pressure can easily lead to tire blowouts, so the pressure should be slightly lower. In winter, tire pressure should be a bit higher than in summer due to thermal contraction and expansion. Therefore, the recommended tire pressure for cars in winter is generally between 250 kPa and 280 kPa.

What are the effects of exhaust pipe leakage in a car?

The effects of exhaust pipe leakage in a car are as follows: Here are the relevant introductions: 1. Increased noise: If the leakage is located before the muffler, it will cause increased noise. The exhaust pipe is installed between the engine exhaust manifold and the muffler, allowing the entire exhaust system to have flexible connections, thereby reducing vibration and noise. 2. Exhaust emissions: If the leakage is before the catalytic converter, it will affect the quality of exhaust emissions, possibly leading to failed vehicle inspections. 3. Power: It has almost no effect on power, as the exhaust pipe discharges waste gases, which have little impact on the engine's operation and driving performance.

How many points can be deducted during the probationary period?

A driver's license during the probationary period has 12 points that can be deducted, as every driver's license has 12 points in a single scoring cycle, regardless of whether it is during the probationary period or not. Here is more relevant information: 1. Consequences of deducting all points: If a probationary driver's license is deducted all 12 points, the probationary vehicle type will be revoked. For B2 and above driver's licenses, deducting 6 points during the probationary period will extend the probationary period by one year. If another 6 points are deducted during the extended period, the driver's license will be revoked. 2. Ministry of Public Security Order No. 139: (1) If a motor vehicle driver accumulates 12 points for road traffic safety violations during the probationary period, the probationary driving qualification for the permitted vehicle type will be revoked. If the revoked driving qualification is not for the highest permitted vehicle type, the highest permitted vehicle type driving qualification shall also be revoked in accordance with the provisions of Article 78, Paragraph 1. (2) For drivers holding licenses for large buses, tractors, city buses, medium buses, or large trucks, if they accumulate 6 or more points but fewer than 12 points during the one-year probationary period, the probationary period will be extended by one year. If they accumulate another 6 or more points but fewer than 12 points during the extended probationary period, the probationary driving qualification for the permitted vehicle type will be revoked.
