1A1B maintenance means one A maintenance and one B maintenance, where A maintenance represents minor maintenance, and B maintenance represents major maintenance. The items included in these two types of maintenance are as follows: Minor maintenance includes: Minor maintenance refers to the routine maintenance items performed at the manufacturer's specified time or mileage to ensure vehicle performance after the car has traveled a certain distance. It mainly includes replacing the engine oil and oil filter, air filter, and cabin air filter. Major maintenance includes: After the vehicle has been used for a certain number of years and kilometers, in addition to the items of minor maintenance, it is also necessary to inspect and replace the vehicle's fuel filter, coolant, transmission fluid, brake fluid, and power steering fluid. At the same time, it is also necessary to check the vehicle's tires, brake pads, belts, and other components.

When I first started maintaining my own car, I didn't understand what 1A1B maintenance meant either. Later, a mechanic explained that it represents two maintenance levels: 1A is a minor service, basically just changing the oil and filters, checking brake fluid, coolant, etc., suitable for every six months or 5,000 kilometers; 1B is a major service, which adds tire and wheel inspections, engine deep cleaning, spark plug checks, etc., typically done annually or every 10,000 kilometers. This classification helps car owners save time and money by preventing issues before they lead to breakdowns. Since buying the car, I've stuck to the maintenance schedule, and the car has remained in good condition with low fuel consumption, especially giving me peace of mind on long trips. Remember, don't delay maintenance dates to avoid unexpected failures. Additionally, different weather seasons, like winter, require extra attention to prevent freezing and starting issues.

As an average car owner, I used to neglect maintenance on my old car, leading to frequent breakdowns. Now I've learned my lesson – the 1A1B system is a phased maintenance approach: 1A covers basic tasks like fluid checks and replacing essential components, while 1B involves more comprehensive inspections including chassis, suspension, and lighting tests. This design makes costs more manageable, with minor services costing just a few hundred yuan, reducing unexpected expenses. I now log mileage and follow the manual for maintenance, which is quick and efficient. Neglecting maintenance can lead to engine damage or brake failure, posing serious safety risks. Therefore, it's crucial to visit a reliable repair shop regularly. Different brands have varying requirements – German cars are stricter, but this system also applies to American models. Maintaining this habit can extend your vehicle's lifespan by over five years.

In the automotive circle, I understand 1A1B as maintenance cycle codes. 1A focuses on core maintenance like changing the oil filter to ensure smooth engine lubrication and stable performance. 1B extends to auxiliary system checks, including battery status, fan belt wear, and other in-depth services. It differentiates intensity, allowing car owners to choose flexibly and avoid piling up all tasks at once. In related topics, Hyundai car sensors will remind you of the timing—it's best not to miss it, otherwise it may affect warranty costs. I recommend doing it on time to prevent 80% of common failures.

How Many More Years Can a Car with 150,000 Kilometers Be Driven?

According to the latest national regulations on vehicle retirement, regular family-use 5-seat sedans and 7-seat SUVs, as long as they are non-commercial private vehicles, have no usage time limit. However, when the mileage reaches 600,000 kilometers, the state will guide the vehicle to be retired. For vehicles older than 15 years, an inspection is required every 6 months, and if the inspection is not passed, the vehicle will be forcibly retired. 1. Retirement: Refers to the phenomenon where a car can no longer be used or is deemed unqualified due to excessive use time or too many problems, ultimately being scrapped. 2. Precautions: It is necessary to frequently replace some easily worn parts and replenish energy for the car. For example, brake pads that wear out after about two years of use should be replaced promptly. Or the fuel pump, even if not replaced, must be cleaned after more than two years of use. Additionally, if the car becomes unstable, it may be due to issues with the shock absorbers in the suspension system. If not repaired or replaced in time, it can be dangerous during high-speed driving or rainy days.

What does 'set' mean on a car display?

When 'set' appears on a car display, it refers to the speed setting switch, which is the cruise speed control indicator. To set the cruise speed, the driver accelerates the vehicle to the desired speed and presses the SET button. Typically, the vehicle speed must exceed 30 miles per hour for this function to work. When using cruise control, pressing the brake pedal will deactivate the cruise speed control. The 'set' function in a car also serves to confirm the standard tire pressure. After adjusting the tire pressure of all four tires to the recommended level, the driver should press and hold the 'set' button for three seconds while observing the speedometer. A warning symbol (an exclamation mark inside parentheses) will appear, and a beep sound will confirm that the tire pressure has been set according to the driver's adjustments. If a tire loses pressure during driving, causing incorrect tire pressure, the system will automatically trigger an alarm.

What Does 160 Horsepower Mean?

160 horsepower is equivalent to the power of a 123w engine. 1 horsepower is approximately equal to 735 watts. It generally refers to metric horsepower rather than imperial horsepower. 1 horsepower equals the work of completing 75 kilogram-force meters in 1 second, also equal to 0.735 kilowatts, or known as metric horsepower. Introduction: The greater the horsepower, the faster the car accelerates, the better the sports performance, the more enjoyable overtaking becomes, and the more exhilarating the driving experience. High-horsepower cars usually have very powerful engines, and the sensory impact of speed and sound combined with the roar of the engine can be very intense. Current Situation: Today, mainstream family cars generally have horsepower between 100-150, mainly with 1.6 and 1.4T engines. Naturally aspirated engines have much lower torque, usually around 150NM, while turbocharged engines in this category can achieve a torque output of 220NM, relative to a typical car weight of 1.3 tons. This is completely sufficient for everyday road driving.

Does Electric Vehicle Charging Produce Radiation?

Electric vehicle charging does produce radiation, but the intensity is very low and has no impact on human health. In fact, electric vehicles use direct current (DC), which has a fixed direction of transmission and an infinitely large cycle of change, theoretically meaning its frequency is zero. In other words, the magnetic field generated by DC is a constant magnetic field, not electromagnetic radiation produced by electrical excitation. Therefore, most of the electromagnetic radiation from electric vehicles comes from the electronic devices installed in the car itself, which is no different from that of fuel-powered vehicles. The United Nations authoritative safety standard for electromagnetic field strength is 100μT. The instantaneous radiation during a mobile phone call can reach 3μT; a hairdryer's radiation can reach 10μT; the national standard for mobile communication base stations is 40μT. However, the radiation from cars does not exceed 20μT, and this applies to all types of vehicles. Some pure electric vehicles even have lower electromagnetic radiation than certain fuel-powered cars. Even near the charging port of an electric vehicle, the radiation is only about 10μT, and if tested inside the car, there is virtually no electromagnetic radiation. Although the electromagnetic radiation from new energy vehicles has no impact on health, it is advisable not to stay inside the car while charging, as the process involves connection to high-voltage interfaces. For safety reasons, it is better to leave the car during charging.
