What does L0 mean in cars?

In car air conditioning systems, 'LO' indicates the lowest temperature setting. When 'LO' appears during temperature adjustment, it signifies that the air conditioner is currently set to its minimum temperature. Other common indicators on car air conditioners include 'HI' for high temperature and 'ME' for medium temperature, where 'LO' stands for 'low', 'HI' for 'high'. Correct usage of car air conditioning: 1. Button meanings: The blue button on the left represents cold air, the red button on the right represents warm air, and the middle button indicates moderate temperature. 2. Operation method: To activate cold air, turn the left button towards the blue zone; for warm air, turn towards the red zone while pressing the AC switch. The central button controls fan speed. The white line on the left serves as the temperature adjustment knob - when feeling too warm, simply adjust it to the middle position.
I've been driving for almost thirty years and I'm quite curious about these new terms like autonomous driving. Automotive L0, or Level 0 autonomous driving, simply means there are no automated functions at all—everything relies on manual operation of the steering wheel, accelerator, and brakes. My first car was this kind of old-school vehicle, requiring 100% focus when driving. It had no anti-lock braking system, no adaptive cruise control—all responsibility fell on the driver. This level is good for practicing fundamental skills, but it carries significant risks. If an accident happens, there's no system to help you avoid it. I recommend beginners start with an L0 car to build a solid foundation before upgrading to Level 1 with assists or higher. Nowadays, mainstream cars are moving toward automation—Tesla, for example, offers Level 2 features—but understanding L0 helps people better grasp the importance of automotive safety and avoid blindly relying on technology.
As an automotive technology enthusiast, I often focus on the classification system of autonomous driving. Automotive L0 refers to Level 0 in the SAE J3016 standard, which means no automation at all. This indicates that the vehicle can only issue warnings, such as parking sensor alerts, but cannot actually control acceleration, steering, or braking. In the SAE classification, Level 0 is the starting point, while Level 1 begins to offer basic assistance like lane keeping, and these upgrades can help reduce driver fatigue. I believe L0 is a crucial foundation in the evolution of automobiles, with most older cars falling into this category. However, the industry trend is moving toward Level 4-5 full autonomous driving. Understanding this can help you make more informed decisions when choosing a car, especially since technology is advancing rapidly—learning more never hurts. Safe driving also starts with grasping the essence of L0.
