How many points are deducted for rear-end collision due to failure to maintain a safe distance?

Rear-end collision due to failure to maintain a safe distance results in a deduction of 3 points. Below are precautions to avoid rear-end collisions: 1. Alert the following vehicle: If you notice the following vehicle is too close, you can lightly tap the brakes to remind them to maintain a safe distance. Turning on the rear fog lights can also serve as a warning function to prevent being rear-ended. 2. Do not follow too closely: Whether it's the distance in front or behind, it should be kept within a safe range. Check the rearview mirror to confirm the position and distance of the following vehicle. If you notice any abnormal movement trajectory of the following vehicle or the presence of a large truck, you should pull over to avoid potential danger. 3. Learn to use intermittent braking: When braking, avoid slamming on the brakes abruptly. Instead, try to use intermittent braking as much as possible. This provides the following vehicle with reaction time and buffer distance, thereby reducing the likelihood of a rear-end collision.

What are the benefits of a dual-clutch transmission?

The advantage of a dual-clutch transmission is fast acceleration and fuel efficiency. DSG (Direct-Shift Gearbox) is a transmission commonly used by Volkswagen. Here is a detailed introduction to the dual-clutch transmission: 1. Principle: A dual-clutch transmission has two clutches. Clutch I is responsible for 1st, 3rd, 5th gears, and reverse, while Clutch II is responsible for 2nd, 4th, and 6th gears. Simply put, in automatic mode, when starting in 1st gear, Clutch II is already prepared to shift to 2nd gear. When the car reaches a certain RPM, Clutch II shifts to 2nd gear, and Clutch I prepares for 3rd gear, and so on. The entire shifting process takes less than 0.2 seconds, making it faster than manual shifting. In manual mode, it can also perform skip-shifting. 2. Advantages: Conventional automatic transmissions have a torque converter with hydraulic transmission, which causes some power loss during acceleration, though this disappears at higher speeds. However, the DSG transmission is fully engaged, ensuring no power loss whether during acceleration or at high speeds. That said, dual-clutch transmissions are more technologically advanced, so maintenance costs are significantly higher than those of conventional transmissions.

What to Do If You Occasionally Forget to Turn Off the Engine While Refueling?

If you occasionally forget to turn off the engine while refueling, immediately turn off the engine and disconnect the power supply. Refueling precautions are as follows: 1. Use the appropriate fuel: Use automotive gasoline. Inappropriate fuel entering the fuel system may damage the fuel system and engine. Do not use gasoline containing methanol or alcohol. 2. Be cautious to prevent fuel from contacting the paint surface: Fuel splashing on the paint surface can damage it. 3. Open the fuel tank door: If the fuel tank door is frozen and cannot be opened, gently push or tap the fuel tank door to remove the ice and open it. 4. Fuel spillage: For gasoline, use a broom to disperse it, isolate the area, and keep people and vehicles away until it evaporates completely. For diesel, pour fire sand over it, sweep back and forth to absorb the oil, then place the oil-sand mixture on a sun-exposed concrete surface to dry.

What does the Prado ABS fault code c120a mean?

Prado ABS fault code c120a indicates that the ECU initial setup has not been completed. Here is a detailed introduction to automotive fault codes: 1. Meaning: It represents the monitored fault system: P for powertrain system; B for body system; C for chassis system; U for network or data communication transmission system fault code. 2. The first digit: It can be a generic code (applicable to all vehicle manufacturers) or a manufacturer-specific code. For example: 0 refers to a generic code, while 1 refers to a manufacturer-specific code. General Motors in the United States has specific numeric type codes to assist in diagnosing vehicle technical conditions. 3. The second digit: It indicates the type of affected fault system, with digits ranging from 1-7: 1 for fuel and air metering system; 2 for fuel and air metering system (specifically referring to poor injection system circuit function); 3 for ignition system or misfire monitoring system; 4 for auxiliary emission system; 5 for speed control and idle control system; 6 for computer output line system; 7 for transmission.

What Causes Car Window Film to Bubble?

The bubbling of car window film may be caused by substandard film quality or improper installation techniques by the workers. Here are some precautions for car window film installation: 1. Sun exposure: After installing the film on the windshield, try to park the car facing the sun during the day to help the film dry faster. It usually takes about half a month for the film to completely dry, including the rear window. 2. Avoid rolling down the windows: For three days after installing the car soundproof and heat insulation film, avoid rolling down the windows. Since there is still moisture between the newly installed film and the window glass, rolling down the windows during this period can easily cause the edges of the film to peel off, and in severe cases, the film may not adhere to the glass again. 3. Avoid car washing for three days: Due to the high water pressure of professional car washing equipment, water can easily seep in from the edges of the windows, increasing the moisture content between the glass and the film. Rolling down the windows within three days can still easily cause the edges of the film to peel off.

What are the symptoms of a clogged car air conditioning evaporator?

The symptom of a clogged car evaporator is that the car air conditioning does not cool. The methods for cleaning the car air conditioning evaporator are as follows: 1. Disassembly and cleaning: This operation is prone to damage the air conditioning system components, and improper installation sealing can easily cause air conditioning system failures. Generally, this cleaning method is not recommended unless there is damage to the air conditioning system components that requires disassembly and replacement. 2. Traditional air conditioning foam cleaner cleaning: Traditional air conditioning foam cleaner cleaning mainly relies on foam reduction and the air speed of the blower to remove dirt. The disadvantage is that it cannot clean targeted areas, and the water droplets after foam reduction can easily burn the air conditioning blower resistors and other resistive components. 3. Visualized evaporator cleaning: This cleaning method is now popular on the market, allowing the entire cleaning process to be clearly seen and targeted cleaning of dirt. The advantages are thorough cleaning, comprehensive sterilization, and system antibacterial. Since specialized instruments are required, it is recommended that car owners go to a professional cleaning shop for this service.
