What are the differences between autonomous driving levels L1-L5?

Autonomous driving levels L1-L5 differ in their degree of automation. Below is a detailed introduction to the distinctions between autonomous driving levels L1-L5: 1. L1 Driving Assistance: The autonomous driving system can assist the driver in completing certain driving tasks. Features such as Anti-lock Braking System (ABS) and Electronic Stability Program (ESP) represent applications at the L1 level. 2. L2 Partial Automation: This level must include systems like Adaptive Cruise Control, Active Lane Keeping System, Automatic Emergency Braking, and Automatic Parking System. 3. L3 Conditional Automation: Autonomous driving is possible in specific scenarios. 4. L4-L5 Full Automation: Capable of performing all driving tasks under all conditions. The traditional driver's cabin is no longer necessary, as the car functions like an extremely intelligent robot.

Which cars are equipped with ZF 8AT transmission?

Cars equipped with ZF 8AT include: Haval H8, Changan CS85-COUPE, Brilliance BMW 3 Series, Audi A8L, Audi Q5, Chrysler 300C, etc. The popularity of ZF 8AT among Chinese brands is largely due to its outstanding performance. Here are specific details about the ZF 8AT: 1. The ZF 8AT not only significantly reduces energy loss in the drivetrain but also meets the demands for lightweight, compact design, and energy efficiency. Traditional 6-speed automatic transmissions emit 186g of carbon emissions per kilometer, while the 8-speed transmission reduces this to 152g per kilometer, making it highly attractive to automakers. 2. The ZF 8AT is a longitudinal transmission, not a transverse one. Currently, most self-owned brand cars on the market feature a transverse engine and transmission design, which maximizes rear passenger space. In contrast, longitudinal transmissions are primarily used in rear-wheel-drive or all-wheel-drive vehicles, enabling balanced chassis weight distribution and significantly enhancing handling performance.

Can I Use the Windshield Wipers After Tinting?

Yes, you can use the windshield wipers after tinting. Here is an introduction to the maintenance methods after tinting: 1. Do not roll down the windows: Avoid rolling down the windows for 3 days after tinting. 2. Do not clean the tint film: Do not clean the tint film or turn on the defroster switch for a week after tinting. Additionally, avoid using solutions containing alcohol or ammonia to clean the film surface. 3. Avoid sharp objects: Do not use sharp objects to lift the edges of the film. Also, avoid directing the air conditioner vents toward the film to prevent rapid thermal expansion and contraction. Note that expired tint film should be handled with care. High-quality films typically have a warranty period of 5 years. After the warranty period expires, car owners should not attempt to remove the film themselves and are advised to visit a specialized repair shop for adhesive removal. 4. Watch for bubbles: If bubbles appear after tinting, they must be addressed at the installation shop within 24 hours.

What Maintenance Is Needed at 25,000 Kilometers?

Maintenance items at 25,000 kilometers are as follows: 1. Air filter element: This mainly depends on the driving conditions. If frequently driven in clean environments, it can be replaced every 15,000 km. If road conditions are harsh, it must be replaced every 10,000 km. 2. Cabin air filter: The replacement cycle for the cabin air filter is 20,000 km, so it should be replaced at this time. 3. Tire rotation: At 20,000 km, tires should be rotated to ensure even wear, and tire pressure should be checked to reduce driving resistance. 4. In addition to regular oil changes, at 20,000 km, check the levels of coolant, brake fluid, power steering fluid, and gear oil. 5. Wiper blades: At 20,000 km, check the wear condition of the wiper blades. 6. Battery: For lead-acid batteries, check the electrolyte level. If it's a maintenance-free battery, this step can be skipped.

Can Different Types of Engine Oil Be Mixed?

Engine oils from different brands cannot be mixed. Engine oils from different brands and grades are formulated with various additives tailored to the working characteristics and environmental requirements of different engines, resulting in differences in viscosity, anti-wear properties, corrosion resistance, anti-knock performance, and volatility. Mixing them may degrade the oil's performance and even cause damage to the engine. Here are the reasons why engine oils should not be mixed: 1. Mixing new and used oil reduces performance. New and used oils should not be mixed. Used oil contains a large amount of oxidative substances, and when mixed with new oil, it accelerates the oxidation and degradation of the new oil, thereby reducing its effectiveness and lifespan. 2. Mixing oils can cause turbidity. Oils from different brands and grades should not be mixed. The chemical additives in different brands and grades of oil may react with each other, reducing lubrication effectiveness and producing acidic or alkaline compounds that accelerate corrosion of engine components.
