What are the body dimensions of the BMW 8 Series Gran Coupe?

The length, width, and height of the BMW 8 Series Gran Coupe are 5088 mm, 1932 mm, and 1410 mm respectively, which are official data. The length of the BMW 8 Series Gran Coupe refers to the distance between two vertical lines perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the car. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The 3.0-liter turbocharged engine used in the BMW 8 Series produces 340 horsepower and a maximum torque of 500 Nm. The engine's maximum power is achieved at 5000 to 6500 rpm, and the maximum torque is available from 1600 to 4500 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. National regulations have specific requirements regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is designed to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, the significance of vehicle width data in national standards lies in ensuring enough space during overtaking to prevent accidents caused by excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5 meters to meet the requirements of public road usage.

What does the exclamation mark warning light in a Mercedes-Benz mean?

The appearance of an exclamation mark on the car's dashboard indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system warning light, transmission fault indicator light, and windshield wiper fault indicator light. Below is a detailed introduction to the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside. If this symbol lights up, it indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, engine oil pressure sensor failure, etc. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating a transmission malfunction or transmission lubricant level below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses. This represents a brake system warning, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Abnormality: An exclamation mark with a horizontal line below parentheses. This represents the tire pressure monitoring warning light, which lights up when the car's tire pressure is too low. Check the car's tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating a fault in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or check yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the problem. In addition, during daily use of the vehicle, the warning lights displayed on the dashboard are divided into two colors, yellow and red: Yellow indicates a fault in the corresponding system, but the problem is not very serious. Reduce speed and proceed to the nearest repair point to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In this case, do not continue driving. Pull over immediately and seek professional assistance to prevent unpredictable dangers to the vehicle and personal safety. It should be noted that when the car is started, all lights will turn on, and the system will perform an automatic check. After the check is completed, the lights will turn off automatically. If a light does not turn on when the ignition is switched on, remains lit, or lights up while driving, it indicates a fault in the corresponding system. In such cases, seek professional help promptly to inspect and eliminate potential safety hazards.

How to Find the Entrance of the S-curve in Subject 2?

Actually, finding the entrance of the S-curve in Subject 2 is not difficult. Before entering the entrance, remember to keep the car body straight and slightly to the left. That is to say, before entering the S-curve entrance, the car body should be aligned with the entrance; secondly, from the driver's perspective, the 12 o'clock position of the steering wheel should not be directly aligned with the center of the road but adjusted slightly to the left, with the car body also slightly to the left, making it less likely for the front wheels to cross the line when entering the curve. The simplest method for the S-curve in Subject 2: 1. Drive into the S-curve test area at a low speed. Before entering the curve, adjust the car to be slightly to the left of the road as described above, with the car body aligned with the entrance; 2. After entering the S-curve, observe the left one-third of the car's front. When it aligns with the right road edge, turn the steering wheel one full turn to the left; 3. After turning, keep the one-third point of the car's front along the road edge. If the alignment is less than one-third, continue turning the wheel half a turn to the left. If it exceeds, slightly turn the wheel back to the right until exiting the first curve; 4. After exiting the first curve, turn the steering wheel an additional half turn to the left. When the left one-third of the car's front aligns with the left road edge, straighten the wheel. Continue observing, and when the raised rivet of the wiper point is 10 cm to the right and aligns with the left road edge, turn the steering wheel one full turn to the right; 5. During the process, pay attention to the rearview mirror to ensure the rear wheels do not cross the line, and straighten the wheel after exiting the curve.

Do I need to bring my ID card for the Subject 1 exam?

You only need to bring your ID card for the exam. The admission ticket and other documents are handled by the driving school, which will distribute them during the exam. Electronic ID cards cannot be used for the exam. If you don't have an ID card, you can apply for a temporary ID card, which has the same validity as a formal ID card. The "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" clearly stipulate that the Subject 1 exam can be taken twice on the same day. If you fail the first attempt, you can retake it for free the second time. If you still fail the second attempt, the Subject 1 exam will be terminated, and you can only reschedule the exam after ten days. The Subject 1 exam consists of 100 questions, divided into single-choice questions and true/false questions, with each question worth 1 point and a total score of 100 points. If you answer 11 questions incorrectly during the exam, the system will automatically submit the test and end the exam. The Subject 1 exam is a computer-based test with a duration of 45 minutes. The content of the Subject 1 exam includes: regulations on driver's licenses and motor vehicle management; road traffic conditions and regulations; road traffic safety violations and penalties; regulations on road traffic accident handling; 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 of wheeled self-propelled machinery, trams, and trolleybuses. Notes for the Subject 1 exam: Candidates should pay attention to their attire and are not allowed to wear slippers. Electronic devices and bags are not permitted in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the instructions and procedures on the large screen and store personal belongings in the lockers before entering the exam room. Upon entering the exam room, the identity verification station will assign a seat. After finding your seat, begin the exam. Ensure the camera is aligned with you and follow exam discipline. If you fail the first attempt, you can retake it the same day. If you fail again, you will need to pay to reschedule the exam. After the exam, queue to collect your score report and sign it. Failure to sign will render the result invalid. There is no limit to the number of times you can reschedule the Subject 1 exam. Each subject can be taken once, and if you fail, you can retake it once. If you do not attend the retake or fail the retake, the exam will be terminated, and you must reschedule the exam. For Subject 2 and Subject 3, there are only five exam attempts. If you fail all five attempts, the previously passed road driving skill test scores will remain valid. There are three subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the exam on road traffic safety laws, regulations, and related knowledge. Subject 2 refers to the field driving skill exam. Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge. The safe and civilized driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in official terms (i.e., the Ministry of Public Security's Order No. 123), there is no such thing as Subject 4.
