The 'set' button in a car is the speed adjustment switch for cruise control. When using cruise control, you need to first press the 'on' button to activate the cruise control function. To set the speed for cruise control, press the 'set' button. Note that cruise control has certain speed limitations. Precautions for using cruise control: 1. Pressing the brake will deactivate cruise control. The speed setting is not cleared and can be resumed to continue cruising at the previously set speed. 2. In complex road conditions or under adverse weather conditions, using cruise control may be dangerous. Please turn off cruise control and drive manually. 3. On downhill slopes, the vehicle may accelerate quickly. You should use the brake to control the speed to prevent loss of control and potential accidents.

I've been driving for over a decade, and the 'set' button in cars generally refers to the cruise control system's setting key. Pressing it locks in the current speed. For example, on highways, after activating cruise control, hitting 'set' makes the car automatically maintain that speed without constant accelerator pedal use. This feature is super practical, especially for long trips—saving effort and fuel. However, remember not to use it during rain, snow, or in congested traffic, as it can be dangerous. Some models even combine 'set' with adaptive cruise control, automatically adjusting speed and following distance based on road conditions, which feels very high-tech. Always pay attention to road conditions and stay alert when using it.

Where to Purchase Compulsory Traffic Accident Liability Insurance for Motorcycles?

Compulsory Traffic Accident Liability Insurance for motorcycles can be purchased from property insurance companies that offer this type of insurance. What is Compulsory Traffic Accident Liability Insurance: Compulsory Traffic Accident Liability Insurance for motor vehicles is a mandatory liability insurance provided by insurance companies. It covers compensation for personal injuries, fatalities, and property losses (excluding the driver and passengers of the insured vehicle) caused by road traffic accidents involving the insured vehicle, within the specified liability limits. This insurance is China's first mandatory insurance system implemented under national law, with premiums uniformly regulated by the state. The primary factor affecting the price of this insurance is the 'number of vehicle seats.' Types of Motorcycle Insurance: In addition to the mandatory Compulsory Traffic Accident Liability Insurance, motorcycle owners can also opt for various commercial insurance policies as needed, such as Motorcycle Damage Insurance, Motorcycle Third-Party Liability Insurance, Motorcycle Passenger Liability Insurance, and Motorcycle Scratch Insurance. Among these, Motorcycle Damage Insurance and Motorcycle Third-Party Liability Insurance are highly recommended for all motorcycle owners.

Do Passengers in the Back Seat Need to Wear Seat Belts?

Passengers in the back seat should also wear seat belts. Here is relevant information about wearing seat belts: 1. Reasons why passengers in the back seat should wear seat belts: Data from the National Highway Traffic Safety Administration (NHTSA) shows that seat belts have saved as many as 13,941 lives in accidents. However, among the annual fatalities in car crashes, half of the victims still perish due to not wearing seat belts. In China, the probability of drivers using seat belts is less than 45%; for front-seat passengers, it is less than 17%; and for rear-seat passengers, it is less than 3%. If rear-seat passengers do not wear seat belts, during an accident, they may not only collide with the front seat backs but also hit the roof, door panels, or windows, leading to injuries. 2. The importance of seat belts: Seat belts are the lifelines of a car, providing protection for both drivers and passengers. When a car is traveling at high speed and experiences a collision or requires emergency braking, the enormous inertial force generated can cause the driver and passengers inside to collide with the steering wheel, windshield, or seat backs, resulting in severe injuries.

Why Are Three-Way Catalytic Converters So Expensive?

The high cost of three-way catalytic converters is due to the presence of precious metals in their honeycomb-structured substrate. Below are specific details about common failures of three-way catalytic converters: 1. Overheating: At normal temperatures, three-way catalytic converters do not possess catalytic capabilities. Their catalysts must be heated to a certain temperature to gain oxidation or reduction abilities. Typically, the light-off temperature for catalytic converters ranges between 250–350°C, while their normal operating temperature is generally between 350–700°C. During operation, higher-quality catalytic converters generate more heat, and oxidation temperatures also rise. When temperatures exceed 850–1000°C, the catalyst coating inside may detach, and the substrate can crack. 2. Chronic Poisoning: The catalysts are highly sensitive to elements such as sulfur, lead, phosphorus, and zinc. Sulfur and lead come from gasoline, while phosphorus and zinc originate from lubricating oil. These four substances, along with their oxide particles formed during engine combustion, easily adhere to the catalyst's surface, preventing contact with exhaust gases and thereby losing catalytic effectiveness—a phenomenon known as 'poisoning.' 3. Carbon Buildup: When a vehicle operates under low-temperature conditions for extended periods, the three-way catalytic converter cannot activate. Carbon deposits from the engine exhaust will accumulate on the catalyst's surface, blocking contact with CO and HC. Over time, this leads to clogged substrate pores, reducing conversion efficiency.

How is the mileage calculated?

The principle is actually quite simple: it involves multiplying the tire's rotation count by its circumference. Since the tire's circumference is fixed, knowing the wheel's rotation count allows calculation of the vehicle's mileage and speed. For example, if a tire has a circumference of 1 meter and rotates 1000 times per minute, the car would travel 1000 meters per minute, or 36 kilometers per hour. The main difference between various types of odometers lies in how they obtain the wheel rotation signal. Most vehicles use electronic odometers. The dashboard essentially functions as a display screen, with parameters controlled by the vehicle's computer. The speed sensor transmits the wheel rotation signal to the computer, which calculates a value based on pre-stored programs and displays it on the dashboard, continuously updating as the car moves. There are two methods for the speed sensor to obtain signals: one is from the transmission output shaft, and the other utilizes the ABS wheel speed sensor's signal. Most vehicle dashboards display two types of mileage: one is the total mileage the car has traveled, and the other is a measurable mileage that can be manually reset by the car owner. Next to most digital displays, there's a small button (cylindrical in shape) that can be held down to reset the measurable mileage.

Can unopened expired antifreeze still be used normally?

Unopened expired antifreeze cannot be used because the active ingredients in antifreeze will precipitate after expiration, causing the liquid to lose its antifreeze capability. At low temperatures, it will freeze and potentially damage engine components, radiators, and other cooling system parts. Antifreeze replacement cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference interval. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze's condition—if it is insufficient, replenish it promptly. If suspended particles, sediment, or signs of deterioration or discoloration are observed, replace the antifreeze immediately and flush the system. Antifreeze composition: The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances. Types of antifreeze: Antifreeze is generally categorized into three types: ethanol-water, glycerin-water, and ethylene glycol-water.
