If the scratch on the car body has exposed the primer, it should be repaired at a scratch repair shop as soon as possible to prevent rusting and corrosion of the surrounding paint. 1. Minor scratches, polish to restore: If there are minor scratches accidentally, the brightness of the car paint can be restored by polishing. Use a polishing wheel with a polishing brightener to remove debris and oxidation layers attached to the car paint, smoothing out the fine scratches. 2. Deeper scratches, apply touch-up paint: If there are deeper scratches, first check if the metal surface is exposed. If the metal surface is not visible, rust will not occur, and you can carefully apply touch-up paint, dotting it with the tip of a brush, then wait for the paint to dry completely. 3. Deep and thin scratches, use colored putty: For very deep and long scratches, colored putty can be used for effective repair. Use sandpaper on the scratched area, being careful not to expand the scratched surface unnecessarily. It is important to clean the dirt thoroughly. Apply the putty carefully to ensure it fully penetrates, then apply a compound and wax.

Why does a car battery suddenly run out of power?

The reasons why a car battery suddenly runs out of power are as follows: 1. The car is not used for a long time: If the car is not used for a long time, the battery will naturally discharge. After a period of time, the battery's power will significantly decrease or even fail to start the vehicle. If this continues for an extended period, the battery's over-discharge will directly affect its lifespan. If the car is not used for a long time due to special circumstances, it is essential to periodically charge the battery directly; otherwise, the battery will quickly age or become damaged and unusable. 2. The car's driving time is too short: Although many people want to own a car, they realize after purchasing one that they don’t have many scenarios to use it. Occasionally driving it out just for grocery shopping can also lead to the battery running out of power. When starting the car, a large current is released, and the consumed electrical energy needs to be replenished by the generator while the engine is running. If each driving distance is too short, the battery will not be sufficiently charged, failing to maintain a full charge, and its power will gradually decrease, eventually leading to an inability to start the car. 3. Failure to turn off in-car electrical devices promptly after turning off the engine: There are many electrical devices in a car. Some devices automatically stop operating and no longer consume power when the engine is turned off, but others require manual shutdown, such as headlights. If these devices are forgotten to be turned off, their power source switches from the generator to the battery, continuously draining the battery until it is empty. Therefore, every time you turn off the engine and leave the car, you must check whether all electrical devices are turned off before leaving to ensure the battery's power is not depleted. Especially, avoid turning on high-power devices like the air conditioner when the car is off, as the battery will drain very quickly.

What are the main reasons for slowing down when driving a motor vehicle in rainy weather?

The main reasons for slowing down when driving a motor vehicle in rainy weather: the braking distance of the car will increase, rainy weather will affect the driver's field of vision, and emergency braking is prone to skidding. When driving a motor vehicle in rainy weather, it is necessary to be more careful and attentive than usual because a layer of fog will form on the car windows, obstructing the view. Additionally, when the rain is particularly heavy, the windshield wipers may not be able to clear the rainwater in time. When driving in rainy weather, it is essential to be cautious, keep an eye on the road conditions, and also pay attention to the speed. The roads outside are very slippery in rainy weather, so it is important to prevent the wheels from skidding.

How Many Questions Are There in Driving Test Subject 1?

There are 100 questions in the driving license test Subject 1. According to the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' the questions are divided into single-choice questions and true/false questions, with each question worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the test, the system will automatically submit the paper and end the test. Subject 1, also known as the Subject 1 theory test or driver theory test, is part of the motor vehicle driving license assessment. The test content includes theoretical foundations of driving, road safety laws and regulations, local regulations, and related knowledge. The test is conducted on a computer with a time limit of 45 minutes. Subject 1 test content: Driving license and motor vehicle management regulations; road traffic conditions and regulations; road traffic safety violations and penalties; road traffic accident handling regulations; basic knowledge of motor vehicles; local regulations; knowledge of braking systems and safety devices for large and medium-sized passenger and freight vehicles; specialized knowledge for wheeled self-propelled machinery, trams, and trolleybuses. Subject 1 test precautions: During the test, candidates should pay attention to their attire; no slippers are allowed, and electronic devices and bags are prohibited in the examination room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen, and store personal belongings in lockers before entering the examination room. Upon entering, verify your identity at the assigned seat and begin the test. Ensure the camera is aligned with you and follow test discipline. If you fail the first time, there is a retake opportunity on the same day. If you fail again, you must pay to reschedule. After the test, queue to collect the score report and sign it; unsigned reports are considered invalid. There is no limit to the number of times you can reschedule for Subject 1. Each subject can be taken once, with one retake if you fail. If you do not take the retake or fail it, the test is terminated, and you must reschedule. For Subject 2 and Subject 3, there are only five test attempts, and they must be scheduled at least ten days apart. If you fail the Subject 3 safe and civilized driving knowledge test, the previously passed road driving skills test results remain valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge test. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, there is no official term 'Subject 4' in the actual regulations (i.e., the Ministry of Public Security Order No. 123).

What is the fuel consumption per 100 kilometers for the Civic?

The Civic currently has 6 latest models on sale, with official fuel consumption data ranging from 5.5-5.9L per 100 kilometers. The fuel consumption for different models is as follows: Civic-2022-240TURBO-CVT Ignite Edition, Dynamic Control Edition, and Sport Edition, equipped with a 182 horsepower engine, have an NEDC fuel consumption of 5.9L per 100 kilometers. Civic-2022-240TURBO-CVT Dynamic Edition, equipped with a 182 horsepower engine, has an NEDC fuel consumption of 5.8L per 100 kilometers. Civic-2022-180TURBO-CVT Elegance Edition, equipped with a 129 horsepower engine, has an NEDC fuel consumption of 5.7L per 100 kilometers. Civic-2022-180TURBO-CVT Comfort Edition, equipped with a 129 horsepower engine, has an NEDC fuel consumption of 5.5L per 100 kilometers. The fuel tank capacity is the same for all Civic models, at 41L. The distance that can be covered on a full tank of fuel is as follows: 2022-240TURBO-CVT Ignite Edition, Dynamic Control Edition, and Sport Edition can cover a distance of 41/5.9*100=694km on a full tank. 2022-240TURBO-CVT Dynamic Edition can cover a distance of 41/5.8*100=706km on a full tank. 2022-180TURBO-CVT Elegance Edition can cover a distance of 41/5.7*100=719km on a full tank. 2022-180TURBO-CVT Comfort Edition can cover a distance of 41/5.5*100=745km on a full tank. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily, requiring more gasoline to be injected for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer controls higher idle speeds to warm up the engine, which also increases fuel consumption.
