BYD Song MAX manual transmission models use an Aisin transmission, while automatic transmission models use a transmission developed by BYD itself. Aisin, established in 1969, is a world-renowned professional developer and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the highest market share globally. The BYD Song MAX manual transmission model is equipped with a 6-speed manual transmission, while the automatic transmission model uses a 6-speed wet dual-clutch transmission. A manual transmission is a gear-shifting device used to alter the engine's speed and torque transmitted to the drive wheels. It enables the vehicle to achieve different traction and speed under various conditions such as starting from a standstill, climbing hills, turning, and accelerating, while also allowing the engine to operate within a more favorable range. The wet dual-clutch transmission features two multi-plate clutches of different sizes, installed coaxially within a sealed oil chamber filled with hydraulic fluid. This design provides better adjustment capability and higher thermal tolerance, allowing the transmission to handle larger torque. For the BYD Song MAX transmission, the following points should be noted during daily use: Avoid prolonged intervals without changing the transmission fluid. Extended periods without fluid changes can damage internal components such as bearings and the transmission housing. Avoid prolonged coasting in neutral. While many experienced drivers may coast in neutral with manual transmissions, doing so with an automatic transmission can cause overheating and produce shocks when shifting back into D gear. Do not shift into D/R gear before the vehicle has come to a complete stop. Some drivers shift into reverse while the vehicle is still moving to demonstrate smooth operation, but this can cause significant damage to the transmission gears and lead to gear grinding over time. Avoid frequently climbing steep slopes in D gear. Automatic transmission vehicles can overheat under high load or shift prematurely, resulting in insufficient power for climbing. In such cases, using manual mode to limit lower gears or switching to sport mode can help protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, it should be transported using a flatbed tow truck with the vehicle in N gear. Towing with a rope or directly dragging the vehicle is not recommended.

I've been driving the BYD Song Max for two years now, and the car mainly features a 6-speed dual-clutch transmission. The gear shifts are quite smooth, and I have no issues driving on the highway every day to pick up and drop off my kids. This dual-clutch design is aimed at fuel efficiency, with an average fuel consumption of around 7 liters per 100 kilometers, which is much better than older automatic transmissions. However, there can be a slight jerkiness at low speeds, so you need to be careful in city traffic jams. I recommend regular checks on the transmission fluid, changing it every 40,000 kilometers to extend its lifespan. Compared to my old Tiguan, the Song Max's transmission is more suited for city driving, with faster acceleration response and stable performance when overtaking on the highway. Safety-wise, I've had no issues, though you need to warm up the car a bit during cold starts in winter. Overall, it offers great value for money and is perfect for practical family use like mine.

What Causes Automotive Electronic System Failures?

Electronic system failures are most likely caused by issues with the electronic parking brake, worn brake pads, problems within the electronic system itself, or battery power supply issues. It is essential to visit a repair shop to use a diagnostic scanner to read the fault codes and perform repairs based on those codes. More information about electronic systems is as follows: 1. Function of Electronic Systems: The primary function is to provide temporary parking assistance in stop-and-go traffic. When parking, after releasing the brake pedal, the auto-hold feature quietly activates, locking the wheels until the accelerator pedal is pressed again, at which point the electronic parking system automatically unlocks the wheels. This process is much faster than manually engaging the electronic parking brake. 2. Preventing Rollback: During parking, the ECU uses sensors installed in the vehicle to determine the vehicle's level and the required braking torque for the wheels, deciding whether to apply the brakes to prevent rollback. The braking force applied by the electronic parking system to the wheels is not excessive—just enough to prevent movement, ensuring the vehicle does not lurch forward when the accelerator is pressed again.

How Often Should the Elysion Throttle Body Be Cleaned?

The throttle body generally needs cleaning between 20,000 to 30,000 kilometers, but there is no strict standard—it can be cleaned when it gets dirty. If there is oil accumulation or carbon deposits in the car's throttle body, it is necessary to promptly visit the car's 4S store or a repair shop to clean the throttle body. Below are the specific reasons for a dirty throttle body and the precautions to take when it is dirty: Specific reasons for a dirty throttle body: A clogged intake tract can cause idle fluctuations, and carbon deposits or oil accumulation in the throttle body are the most common causes of unstable idle. Carbon deposits in the throttle body can affect its opening degree and air intake, leading to erratic engine speed fluctuations and strong vibrations when the car is started cold. Precautions for a dirty throttle body: Severe oil accumulation or carbon deposits in the throttle body, including a dirty intake tract, can make it difficult to start the car in cold weather. A dirty throttle body requires cleaning, and throttle body cleaning itself is considered a routine maintenance task. Spark plugs can also accumulate carbon deposits, which can be cleaned to restore their activity.

What does the yellow exclamation mark on the Elysion dashboard mean?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. Here is a detailed introduction to the exclamation mark warning light: General faults: An exclamation mark inside a triangle: If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic transmission fault: A yellow gear with an exclamation mark inside: This is the automatic transmission fault warning light, indicating a fault in the transmission or transmission lubricant level below the normal range. The transmission oil should be replaced promptly. Brake system fault: An exclamation mark inside a circle with parentheses: This represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire pressure abnormality: An exclamation mark with a horizontal line below parentheses: This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark: This is the lighting fault indicator, indicating a malfunction in one of the car lights. Solution: Visit a 4S shop for inspection as soon as possible, or check it yourself by focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem. In addition, during daily use of the vehicle, the warning lights displayed on the dashboard are divided into two different colors: yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point for maintenance to eliminate potential safety hazards in time. Red indicates a very serious problem in the corresponding system. If this occurs, do not continue driving. Pull over immediately and call for professional assistance to prevent unpredictable dangers to the vehicle and personal safety caused by forced driving. It is important to note that when the car is started, all lights will turn on as the system performs an automatic check. After the check is completed, the lights will turn off automatically. If a light does not turn on when the ignition is switched on, remains lit without turning off, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly for inspection and elimination of potential safety hazards.

Can I add water if my car runs out of coolant?

You can add water to your car's coolant system. When the coolant level is below the MIN mark and no coolant is available, water can be used as a temporary substitute. However, using water as a long-term replacement for coolant is not recommended because prolonged use can lead to scale buildup on the surfaces of the radiator and water jacket, which increasingly impairs heat dissipation and is difficult to remove. The following section explains the functions of antifreeze: Anti-corrosion function: The engine and its cooling system are made of metal. These metals can corrode and rust over time when exposed to water at high temperatures. Antifreeze not only prevents corrosion in the engine cooling system but also has anti-corrosion and rust-removal properties. Anti-scaling function: High-quality antifreeze is made with distilled water and contains anti-scaling additives, which not only prevent scale buildup but also help remove existing scale.

Can Car Batteries Spontaneously Combust?

It depends on the specific circumstances. Batteries inherently involve chemical reactions that convert chemical energy into electrical energy, generating heat in the form of internal energy. If the temperature does not exceed the battery casing's tolerance and the vent holes remain unblocked, explosions are generally unlikely. However, improper usage, particularly during charging, can easily lead to accidents. Additional details are as follows: 1. Lead-acid batteries: The most cost-effective and common type, used in fuel-powered vehicles to power systems like headlights and air conditioning. These batteries require replacement every 2-3 years. Their advantages are obvious—low cost and safety—while their drawbacks include short lifespan and low energy density. 2. Nickel-metal hydride (NiMH) batteries: A high-performance battery type that offers the same capacity as lead-acid batteries at half the weight. Toyota HEVs commonly use this battery, but its disadvantages include accelerated degradation from overcharging or discharging, and unavoidable capacity loss during use. Toyota’s non-plug-in hybrid models effectively mitigate this issue while maintaining safety. 3. Lithium-ion batteries: The most widely used in electric vehicles, such as Tesla, BYD, and other major manufacturers. Their biggest advantage is affordability, making them a cost-effective and safe alternative. 4. Lithium ternary batteries: Often used in imported models like BMW or Renault, these batteries feature high energy density and superior safety compared to lithium iron phosphate batteries.

What causes oil leakage in motorcycle sediment bowls?

Common main causes of vehicle oil leakage: poor quality of products (accessories) and materials, as well as inferior craftsmanship; structural design issues. Improper assembly and adjustment: unclean mating surfaces; damaged, displaced, or improperly installed gaskets. Measures to prevent vehicle oil leakage are as follows: Pay attention to the role of gaskets: Gaskets between components in static parts of the vehicle (such as joint end faces, end covers, housings, cover pads, flat enamel covers, etc.) play a role in preventing leakage and sealing. If the material, manufacturing quality, or installation does not meet technical specifications, they will fail to seal and prevent leakage, potentially leading to accidents. Replace failed oil seals promptly: Many parts of the vehicle (such as oil seals) may leak oil due to improper installation, misalignment between the shaft neck and the oil seal edge, or wobbling. Some oil seals may lose elasticity due to rubber aging after prolonged use, leading to seepage, which should be promptly addressed by replacement.
