Is it okay to keep the air conditioning on when the car is not running?

Keeping the air conditioning on when the car is not running is very dangerous. When the car's engine is running, if the gasoline in the cylinders does not burn completely, it produces high concentrations of carbon monoxide. If the air inside the car cannot circulate, the carbon monoxide emitted by the engine can leak into the car, gradually accumulating and increasing its concentration, leading to poisoning. Here is some information about car air conditioning: 1. Introduction: The car air conditioning device (air-conditioning-device) is referred to as car air conditioning. 2. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it also creates good working conditions for the driver and serves as an important ventilation device for ensuring safe driving.

As someone who has been driving for over a decade, I can tell you from personal experience that keeping the air conditioning on while the car is stationary is definitely not a good idea. One summer when I was waiting for a friend and wanted to cool off in the car, I left the AC running for half an hour, and the battery died completely, leaving me unable to start the car. I had to call for roadside assistance and pay to get it fixed. The main reason is that the air conditioning relies on the battery for power, and if the car isn't running, the alternator doesn't work, which can easily drain the battery. Doing this long-term can also cause excessive wear on the compressor, increasing maintenance frequency. Additionally, if you run the AC with the engine on, fuel consumption rises quickly, wasting gasoline unnecessarily. So, I recommend keeping the AC use to a minimum—no more than ten minutes—or simply opening the windows for ventilation. If you really need to cool down, try using the fan mode instead.

From an environmental perspective, this issue deserves more attention. Keeping the car's air conditioning running while the vehicle is stationary wastes energy and creates pollution. Engine idling emits more exhaust, which is harmful to both air quality and the climate. We should advocate for fuel conservation and carbon emission reduction, such as pre-cooling the car only before driving rather than running the AC for extended periods while parked. Actually, using fans or opening windows while waiting in parking lots can save significant resources. This habit also protects the environment, making cities fresher. In short, for the sake of our planet, let's avoid developing such wasteful habits.

Simply put, the battery power is tight, and the high consumption of the air conditioning system leads to frequent vehicle startup failures, requiring regular maintenance checks. The increased load on the compressor accelerates wear and raises replacement costs. Engine idling wastes fuel and emits toxic gases, posing safety risks, especially in poorly ventilated enclosed spaces. The basic solution is to control usage time, use ventilation mode more often, and minimize air conditioning usage.

What items need to be replaced during a car's first maintenance?

Items that need to be replaced during a car's first maintenance include: engine oil, oil filter, cabin air filter, and engine air filter. Other tasks involved in the first maintenance are: 1. Checking the levels of coolant, battery fluid, and windshield washer fluid; 2. Inspecting the brake and clutch fluid levels, as well as the power steering fluid level; 3. Examining tire pressure and wear, and tightening screws to the specified torque. The benefits of a car's first maintenance include: 1. Ensuring the vehicle performs at its best; 2. Improving the vehicle's efficiency and reducing wear on parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle issues; 5. Reducing noise and environmental pollution; 6. Maintaining the vehicle's appearance and preventing damage.

Why Wear Gloves for Subject One Exam?

Wearing gloves during the Subject One exam is to prevent sweaty palms, which could otherwise lead to accidental touches on the answers. Precautions for the Subject One exam: 1. Arrive early: Regardless of which driving school you're from, try to arrive about half an hour early before the exam; since most examinees are taking Subject One for the first time, arriving early allows the team leader from each driving school to distribute admission tickets and explain exam techniques and key points to pay attention to. 2. Bring your ID card: Carry your ID card, as it will be scanned along with the admission ticket on a card reader to assign random seat numbers before entering the exam hall. 3. Find your seat: After being assigned a seat number, locate your seat; it's especially important not to click "Confirm" on the screen until the invigilator instructs you to do so. Simply sit in your seat without any operations (otherwise, you may be asked to leave the exam hall).

What Do the Numbers on Wheel Sizes Mean?

Automotive tire numbers and letters represent tire parameters. Taking 215/70R15 as an example, 215 indicates the tire section width is 215mm; 70 is the aspect ratio, meaning the tire sidewall height is 70% of the tire section width, R stands for radial tire, and 15 means the tire fits a 15-inch wheel hub. Below is relevant information about tires: 1. Tire lifespan: The wear life of tires is 30,000-50,000 kilometers. If the tire hasn't reached the wear limit or mileage but has been in use for 5 years or shows extensive sidewall cracks, it should be replaced. 2. Tire material: The main component of tires is rubber. The maximum storage and anti-aging duration for rubber, from natural latex to EPDM and nitrile, does not exceed 10 years, with the average service life of various rubber products in use being 3-5 years.

How to Drive a Car with Manual and Automatic Transmission?

Car with manual and automatic transmission has M+ and M- buttons, which can be used to set the gear of the vehicle and switch between manual mode and automatic mode. Switch to manual mode in the following situations: 1. When accelerating to overtake. Manual mode accelerates faster and more powerfully than automatic mode, so it is better to switch to manual mode when you want to overtake. 2. When going downhill for a long distance. In this case, using manual mode to go downhill is more convenient and can reduce the number of times the car brakes, thereby reducing tire wear. 3. When encountering continuous undulating roads. At this time, using manual mode can not only improve driving stability and safety but also reduce the wear and tear on the vehicle caused by continuous braking. 4. When climbing a slope. Switching to manual mode at this time can give the vehicle more power, making it easier to climb the slope.

What does the 215/50r17 tire mean?

Automotive tire specification 215/50r17 refers to a tread width of 215mm; 50 is the aspect ratio (tire height ÷ tread width) indicating 50%; r denotes that the tire has a radial structure with steel belts; 17 indicates the rim diameter is 17 inches. When using tires, pay attention to the following points: 1. Develop the habit of regularly checking tire pressure: Pressure is key to extending tire lifespan—frequently exceeding normal pressure by 20% reduces tire life by 10%; if frequently below normal pressure by 30%, tire life decreases by 52%. 2. Maintain consistent tire pressure: Tire pressure is the lifeblood of tires. Low pressure increases tire body deformation, leading to sidewall cracks, excessive heat generation, rubber aging, ply fatigue, and cord breakage. 3. Regularly remove foreign objects from tires: While driving, small stones often get lodged in the tread grooves. If not promptly removed, these stones can puncture the tire over time, causing leaks or blowouts.
