What does M1 and M2 mean in an automatic transmission?

In an automatic transmission, M1 refers to the first gear in manual mode, and M2 refers to the second gear in manual mode. M1 is typically used for normal starts or climbing steep slopes, with speeds around 10 kilometers per hour. M2 is used for accelerating after starting, driving at low speeds near other vehicles, or climbing steep slopes, with speeds around 20 kilometers per hour. You can switch directly between M mode and D mode without any time or RPM restrictions. The transmission will automatically match the appropriate gear based on the real-time speed. When in M mode, the dashboard will display the current gear, and you can shift up or down by pushing or pulling the gear lever. If the gear is in D mode and you want to overtake, the speed won't increase rapidly even if you press the accelerator hard, as the transmission will still shift up sequentially, resulting in a slower response time. However, if you switch to M mode, the vehicle can utilize the high torque of a lower gear to accelerate instantly when the driver presses the accelerator, allowing for quicker and safer overtaking maneuvers while saving time.

What Octane Gasoline is Suitable for Volkswagen Sagitar?

"The Sagitar should use 95 octane gasoline. This octane rating is recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline octane in the user manual, you can also find it on the fuel tank cap, which will also indicate the recommended octane. Generally, the octane can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is higher, 98 octane gasoline is recommended. However, with the use of new technologies, the octane cannot be solely determined by the compression ratio. Engines with high compression ratios can also be tuned to use lower octane gasoline because, apart from the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline octane, the higher the octane rating and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the Sagitar occasionally uses the wrong octane gasoline, simply switch back to the correct octane after consumption. However, long-term use of the wrong octane can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane rating can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Due to the significantly lower octane rating, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will arise during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring."

What is the reason for not being able to pull out the key in an automatic transmission car?

The reason for not being able to pull out the key in an automatic transmission car is that the P gear is not properly reset. After the engine is turned off, if the gear is not fully returned to the P position and fails to trigger the electronic sensor, the car owner should check if there are any obstructions in the gear slot. After removing any obstructions, start the car, shift the gear again to ensure it is fully reset, and then the key can be pulled out. Sometimes, the key may also become immovable in an automatic transmission car. This is due to the car's steering wheel automatic locking function, which is an anti-theft feature. It usually occurs when the steering wheel is accidentally turned left or right when parking and turning off the engine, or when the wheels are not aligned properly when parking. The force applied can cause the steering wheel to turn, activating the self-locking function, which locks the steering lock pin and the steering column together, making the steering wheel immovable and the key unable to turn. In this situation, while gently turning the key with your right hand, you can wiggle the steering wheel left and right with your left hand, and the key will then turn.

How Many Questions Are There in the Driving License Subject 4 Exam?

According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," Subject 4 consists of a total of 50 questions, each worth 2 points, totaling 100 points. Questions 1-10 are true/false questions; questions 11-40 are single-choice questions; and questions 41-50 are multiple-choice questions. The exam includes various question types such as image analysis, animated case studies, and text descriptions. The scope of Subject 4 covers driving knowledge under adverse weather and complex road conditions; identification of common traffic signs, markings, and hand signals; accident rescue and handling of common hazardous materials; comprehensive judgment of violations and case analysis; emergency avoidance knowledge; safe driving knowledge; and driving ethics and civilized driving knowledge. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," there is no limit to the number of attempts for Subject 1 and Subject 4. If the first attempt on the day is unsuccessful, a retake can be conducted on-site. If the retake is also unsuccessful, a new appointment must be made, and no additional fees are required for retakes. However, it is important to note that the validity period of the driving skill test permit is three years. If the applicant fails to complete the exams within this period, the results of any previously passed subjects will be invalidated. Subject 4, also known as the Subject 4 theory test or driver theory test, is part of the motor vehicle driving license assessment. After the implementation of the Ministry of Public Security's Order No. 123, Subject 3 was divided into two parts: the road test and the addition of a safety and civilization knowledge test, commonly referred to as "Subject 4," which assesses "driving ethics." Subject 4 is the colloquial term for the Subject 3 safety and civilization driving knowledge test and is not a separate subject. Because this test is conducted after Subject 3, it is commonly referred to as the Subject 4 exam. Officially, there is no Subject 4. The safety and civilization driving knowledge test is conducted after Subject 3. Subject 4 Exam Notes: Exam Duration: The exam lasts 45 minutes, and incorrectly answering 10 points (5 questions) will terminate the exam. Number of Questions: Depending on the type of driving license being pursued, 50 questions are randomly selected from the corresponding Subject 4 question bank, each worth 2 points. Question Types: The exam includes single-choice questions (including true/false questions) and multiple-choice questions, with question types such as animated questions, image-based questions, scenario recognition questions, and text-based questions. Retake Notes: If Subject 4 is not passed, only Subject 4 needs to be retaken. The driving school will schedule the retake, and there is no limit to the number of retakes. No additional fees are required for retakes. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3, with Subject 3 divided into two parts. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge test; Subject 2 refers to the field driving skills test; and Subject 3 refers to the road driving skills and safety and civilization driving knowledge test.

How Many Chances Are There on the Day of the Subject 1 Exam?

The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" clearly stipulates that on the day of the Subject 1 exam, candidates can take the test twice. If the first attempt is unsuccessful, a second free retake is allowed. If the second attempt is also unsuccessful, the Subject 1 exam for that day is terminated, and the candidate can only reschedule the exam after ten days. There is no limit to the number of times the Subject 1 exam can be scheduled. Subject 1, also known as the Subject 1 theory test or driver's theory test, is part of the motor vehicle driver's license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The test format is computer-based, with a time limit of 45 minutes. The passing score for the Subject 1 exam is 90 points. The test consists of 100 questions, divided into single-choice and true/false questions, with each question worth 1 point, totaling 100 points. If 11 questions are answered incorrectly during the exam, the system will automatically submit the test and end the exam. Subject 1 exam content includes: driver's 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 exam precautions: Candidates should pay attention to their attire during the exam; no slippers are allowed, and electronic devices and bags are prohibited in the exam 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 the locker before entering the exam room. In the exam room, the identity verification area will assign seats. After finding your seat, begin the exam. Ensure the camera is aligned with you and adhere to exam discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After the exam, queue to collect your score report and sign it. Unsigned reports are considered invalid. There is no limit to the number of times the Subject 1 exam can be scheduled. Each subject exam allows one retake if the first attempt is unsuccessful. If the retake is not taken or is also unsuccessful, the exam is terminated, and the applicant must reschedule. In contrast, Subject 2 and Subject 3 exams only allow five attempts each, and rescheduling must be done ten days later. If the Subject 3 safe and civilized driving knowledge test is unsuccessful, the passed road driving skills test scores remain valid. There are three subjects in the driver's license exam: 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, the official term (as per the Ministry of Public Security's Order No. 123) does not include Subject 4.
