How to Break in a New Car for Better Fuel Efficiency?

Warm up the engine when starting cold: It's necessary to warm up the engine during a cold start. After the vehicle has been parked, the engine components may not be fully lubricated. Proper warm-up helps the oil form a protective film between the engine parts and other components. Reduce abnormal engine wear during operation by maintaining reasonable driving speeds: Keeping a reasonable speed can help a car in the break-in period achieve better fuel efficiency. Generally, the most fuel-efficient speed for most cars is not very high, typically falling within the range of 65-90 km/h. To save fuel, try to keep the vehicle's speed within this range. Timely maintenance is crucial: New car maintenance is essential, especially for vehicles in the break-in period. Follow the manufacturer's recommendations in the owner's manual for timely oil changes and other maintenance tasks. Additionally, inspect the car's chassis regularly. Proper maintenance can help monitor daily fuel consumption. Avoid prolonged high-speed driving: Be cautious when driving a new car on highways for extended periods. Continuous high-speed driving can cause the engine to operate under high load for too long, potentially leading to increased component wear, which is not conducive to the car's break-in process.

How to Escape When a Car Falls into Water?

When a car falls into water, it is crucial to stay calm and find a way to escape as quickly as possible. Below is a detailed guide on how to escape from a submerged car: 1. Opening the Door to Escape: If the car has just fallen into the water, occupants must remain calm and immediately unfasten their seatbelts and open the doors, as this is the safest and quickest way to escape. Activate the electronic central locking system immediately to prevent door lock failure. When the water level is around 30 cm, the doors can still be opened. However, when the water reaches about 60 cm, the doors will no longer open. If the water levels inside and outside the car are equal, the doors can be opened. Therefore, if the initial escape opportunity is missed, use the precious time before the cabin is completely submerged to let water in. Once the water levels inside and outside are equal and the pressure balances, quickly open the door to escape. 2. Breaking the Window to Escape: If the doors are not opened in time, as water floods the car, the electrical system may fail, making it impossible to open the doors or windows. In this case, use a sharp object inside the car to break the window. The best tool for this is a safety hammer. When using the safety hammer, aim for the window that is still above water, typically the side or rear window. Strike the edges or corners of the window glass, not the center. If no safety hammer is available, use other sharp objects like the metal rods of a car headrest, high heels, or an umbrella to break the window. 3. Escaping Through the Trunk: Since most cars are front-heavy, the front will sink first, causing the rear to tilt upward. Use this time before the rear is submerged to climb into the back seat. Fold down the rear seat backrest, locate the trunk lock cover, and pry it open with a key or another hard object. Turn the white lock cylinder clockwise to pop open the trunk (methods may vary by car model). Once outside the car, keep your face upward, follow the bubbles to the surface, and try to grab onto floating objects while swimming to the surface for help.

How is the purchase tax on imported vehicles collected?

The calculation method for the purchase tax on imported vehicles is as follows: Taxable price = Customs duty-paid price + Customs duty + Consumption tax, Tax payable = Taxable price × 10%. Below is a detailed explanation regarding the purchase tax on imported vehicles: 1. Legal basis: The "Administrative Measures for the Collection of Vehicle Purchase Tax" came into effect on January 1, 2006, setting the vehicle purchase tax rate at 10%. This is the same as the tax rate currently collected by the traffic management authorities. The new "Measures" will replace the original "Interim Regulations on Vehicle Purchase Tax". The vehicle purchase tax is levied once, and vehicles that have already been taxed will not be subject to additional taxes before scrapping or during resale. 2. Role of vehicle purchase tax: Vehicle purchase tax plays an important role in national revenue, serving functions such as reasonably raising construction funds, standardizing government actions, and adjusting income disparities.

At What RPM Should You Shift Gears in a Manual Transmission?

It depends on the car's engine. Generally, shifting between 2000-3000 RPM is appropriate. Shifting RPM for low-revving engines: Low-revving engines can deliver significant torque and power at lower RPMs. For such engines, shifting around 2000 RPM, or even between 1500-1800 RPM, is suitable. Shifting RPM for high-revving engines: High-revving engines exhibit a proportional relationship between torque and RPM within certain limits. Shifting at 3000 RPM will noticeably feel more powerful compared to shifting at 2000 RPM. Therefore, except for first gear, other gears can be shifted at 3000 RPM or even 4000 RPM. This approach not only enhances power but also helps reduce carbon buildup.

What are the four mandatory insurances for vehicles?

Compulsory Traffic Accident Liability Insurance is mandated by the state, and vehicles cannot be driven on the road without it. The other three non-mandatory insurances are Vehicle Damage Insurance, Third-Party Liability Insurance, and Passenger Liability Insurance, which can be purchased based on individual needs. Below are detailed explanations of each insurance type: Compulsory Traffic Accident Liability Insurance: This insurance ensures that the insurance company compensates the victim according to the contract after an accident. However, it is important to note that the victim does not include the policyholder or the passengers inside the vehicle. Vehicle Damage Insurance: Vehicle Damage Insurance is a type of commercial auto insurance. It covers damages to the vehicle caused by accidents involving the policyholder or an authorized qualified driver. The insurance company will compensate within the scope of liability. The coverage of Vehicle Damage Insurance has been expanded to include vehicle self-ignition, standalone glass breakage, engine water damage, vehicle theft, no-deductible coverage, designated repair shops, and third-party liability for untraceable accidents. Third-Party Liability Insurance: This insurance covers third parties other than the vehicle owner and the insurance company. Accidents where the owner hits another driver are inevitable while driving. Purchasing this insurance allows the insurance company to bear part of the compensation according to regulations, thereby reducing the owner's financial burden. Passenger Liability Insurance: Passengers are often present in the vehicle. If an accident occurs, the insurance company will compensate according to the contract if this insurance is purchased. Important considerations when purchasing auto insurance: Insurance Lapse: A lapse occurs when the vehicle's insurance coverage period has expired without renewal. If insurance is purchased after a lapse, the vehicle must be inspected by the insurance company. Purchase Timing: Auto insurance can generally be purchased after obtaining the new vehicle's certification. For renewal, insurance can be purchased within one month before the expiration of the previous policy. Coverage Selection: New vehicles should ideally have comprehensive coverage, especially for new drivers. This includes Vehicle Damage, Third-Party Liability, Theft, Standalone Paint, and Standalone Glass coverage, among others. However, this should also be based on individual financial circumstances. Choosing a Reputable Company: It is advisable to avoid small insurance companies due to their lack of service guarantees and unreasonable pricing. Opt for well-known large companies with good reputations. You can visit the websites of major insurance companies for more information. Policy Terms: When purchasing auto insurance, inquire about basic policy terms, especially the exclusions, to understand under what circumstances the insurance company will not compensate. This helps prevent disputes in the future.

Can You Make a U-Turn Over a Single Yellow Line in the Middle of the Road?

If it is a single yellow dashed line, you can make a U-turn when it does not affect the normal flow of traffic. However, if it is a single yellow solid line, making a U-turn is not allowed and is considered a traffic violation. According to the "Road Traffic Safety Law," violators will be fined 200 yuan and receive 3 demerit points. Generally, on long stretches of road, there are usually white solid lines, dashed lines, or yellow solid or dashed lines in the middle section or before intersections. As long as the line is solid, U-turns are prohibited. Scenarios where U-turns are allowed: Intersections with U-turn signs: If there is a clear U-turn sign at the intersection, you can make a U-turn. If there is a U-turn traffic light, you must follow its instructions. If there is no traffic light, you should assess the situation and make the U-turn without obstructing other vehicles or pedestrians. Intersections without explicit "No U-turn" or "No Left Turn" signs: If there is no explicit prohibition, U-turns are allowed. "No explicit prohibition" means the intersection lacks signs like "No U-turn," "No Left Turn," or a solid center line. In such cases, you can safely make a U-turn. Yellow grid lines also allow U-turns: Yellow grid lines are no-parking zones, typically marked at intersections prone to congestion due to temporary stops, important facility entrances, or other designated areas. Stopping on these lines (including waiting at traffic lights) is a violation. Although parking is prohibited in yellow grid zones, U-turns are allowed as long as there is no central barrier. A yellow grid line without a barrier is equivalent to "U-turn permitted." When "No Left Turn" and "U-turn Permitted" signs coexist: U-turns are allowed, but left turns are prohibited. Note that "No U-turn" is not the same as "No Left Turn." Things to note when making a U-turn at an intersection: Observe road markings: If the line is solid, U-turns are prohibited under any circumstances. Continue driving to find a suitable spot. If there is a "No Left Turn" sign, even if "No U-turn" is not mentioned, U-turns are still prohibited at that intersection because the actions of left turns and U-turns are closely related—a U-turn requires a left turn first. U-turns must be made from the innermost left-turn lane. If you are in the second left-turn lane, you cannot make a U-turn at that intersection. Always yield to through traffic when making a U-turn. If you interfere with the normal flow of through traffic, you will bear full responsibility for any accidents. Near the intersection stop line, lanes usually have guiding arrows for drivers to choose their direction. The leftmost lane may not always have a left-turn arrow. On some roads, if there is a straight arrow, U-turns are prohibited even if there are no explicit "No U-turn" signs. Making a U-turn on a crosswalk is also a traffic violation.
