B gear refers to engine braking. The B gear on a car is a rarely seen gear position, which generally appears on Japanese cars. Toyota's hybrid models are equipped with the B gear, such as the Toyota Corolla, Toyota Prius, and Lexus 200h. This gear can be used when going downhill, equivalent to the L gear on a car. When driving downhill with the B gear engaged, the motor intervenes to achieve engine braking, thereby reducing the car's speed. If the car is traveling on a long downhill section, relying solely on the braking system to slow down is very dangerous. If only the braking system is used for deceleration, the car's brake discs and pads may overheat, and in severe cases, this can lead to brake failure. Many automatic transmission models are equipped with an L gear, which stands for "low," meaning low-speed gear. When driving downhill, using the L gear keeps the car's transmission in a lower gear, allowing the engine's braking effect to slow the car down.

What items are generally replaced during routine car maintenance?

During routine car maintenance, the following items are typically replaced: engine oil and oil filter, coolant, windshield washer fluid, cabin air filter, and brake fluid. Engine oil and oil filter: Engine oil and oil filters basically need replacement during every maintenance service. Automotive engine oil is generally categorized into three types: mineral oil, semi-synthetic oil, and fully synthetic oil, each with different replacement intervals. Coolant: Automotive coolant not only provides antifreeze protection but also helps cool the engine during operation when high temperatures are generated. In winter when temperatures drop, coolant prevents low-temperature damage to the engine. Generally, coolant should be replaced every three years or 50,000 kilometers. Windshield washer fluid: Windshield washer fluid is primarily used for cleaning windshield contaminants and should be refilled promptly when depleted. During winter usage, it's recommended to use antifreeze washer fluid to prevent freezing damage to the fluid reservoir and ensure normal operation. Cabin air filter: The cabin air filter filters incoming air to maintain clean airflow from the air conditioning system. Under normal circumstances, replacement every 1 to 2 years is sufficient.

Are Brake Pads Different for Front and Rear?

Automobile brake pads are indeed different for the front and rear. Generally, the front brake pads of a car are larger than the rear ones, and the front and rear brake pads cannot be used interchangeably. The front brake pads wear out faster than the rear ones, so they need to be replaced more frequently. The rear brake pads are more durable. Although the front and rear brake pads are made of the same material, the front brake pads are usually more expensive than the rear ones. The replacement interval for front brake pads is typically between 30,000 to 60,000 kilometers, while the rear brake pads should be replaced every 60,000 to 100,000 kilometers. Car owners should inspect the brake pads every 5,000 kilometers. If the brake pads are thinner than 5mm, they should be replaced promptly to avoid affecting vehicle performance. Brake pad maintenance methods include: high-temperature protection to prevent corrosion of the braking system, cleaning oil stains from brake discs, brake drums, and brake pads, ensuring proper heat dissipation of the brake discs, regular replacement of brake fluid, and periodic checks of the thickness of brake pads or brake shoes.

Can I deduct points the day before my driver's license points are about to expire?

No. 1. If there are unpaid fines, the points will carry over to the next cycle: The cumulative scoring cycle for road traffic safety violations is 12 months, with a maximum of 12 points, calculated from the date the motor vehicle driver's license is first issued. If a motor vehicle driver's points do not reach 12 points within a scoring cycle and the fines have been paid, the points will be cleared; if the points do not reach 12 points but there are still unpaid fines, the points will carry over to the next cycle. 2. Accumulating 12 points requires attending relevant knowledge education: If a motor vehicle driver accumulates 12 points within a scoring cycle, their driver's license will be detained by the public security traffic management department. The motor vehicle driver must report to the traffic management department of the public security authority at the place where the driver's license was issued or where the violation occurred within 15 days to receive seven days of education on road traffic safety laws, regulations, and related knowledge, and must take the subject one exam. 3. Refusal to attend learning results in suspension of the driver's license: If a motor vehicle driver's points reach 12 points and they refuse to attend the learning notified by the traffic management department of the public security authority or take the exam, the traffic management department of the public security authority will announce the suspension of their motor vehicle driver's license.
