What do the gear letters on an automatic transmission car represent?

Automatic transmission gear letters represent the following: 1. P stands for Park, used when the car is parked and not in use. In this position, the wheels are mechanically locked to prevent rolling. 2. R stands for Reverse, used when backing up. 3. N stands for Neutral, used for temporary stops (such as at a red light). To prevent the vehicle from rolling on a slope, the brake must be applied. 4. D stands for Drive, also known as the driving gear, used when moving forward. 5. L stands for Low gear, used when going downhill or on long descents. This limits the car to the lowest gear, allowing the engine to assist in braking, reducing the need for prolonged brake use and preventing brake overheating. 6. S stands for Sport mode. When engaged, gears can be freely switched, but the shift timing is delayed to keep the engine at higher RPMs for increased power. This mode significantly increases fuel consumption.

Where is the terminal device number of the car?

The terminal device number of a car can usually be found on the vehicle's driving license, which corresponds to the last six digits of the vehicle identification number (VIN). The VIN, also known as the vehicle identification code, is an alphanumeric sequence typically consisting of 17 characters. Currently, there are two main standards for vehicle identification numbers: the EU's ISO 3799 standard and the North American standard, with the latter being more stringent and compatible. Under the North American VIN standard, the specific meanings of the digits are as follows: 1. Digits 1 to 3 represent the manufacturer, brand, and type. 2. Digits 4 to 8 indicate vehicle characteristics, including vehicle type, chassis, engine model, rated weight, and other details. 3. The 9th digit is a check digit. 4. The 10th digit represents the vehicle's production year. 5. The 11th digit indicates the assembly plant where the vehicle was produced. 6. The last six digits are the vehicle's production serial number.

How Deep of Scratches Can Polishing Remove?

Car polishing can remove scratches. For issues like oxidized, dull, or lackluster car paint, as well as scratches on the body, car polishing can effectively address these problems, making the paint surface smoother and shinier. Additionally, car polishing can clean the body, effectively removing dirt and corrosive substances, thereby restoring the cleanliness of the paint surface. Polishing the car body before waxing or sealant application can enhance the results and prolong the duration of the effects. The main functions of car waxing are: 1. Waterproofing and protecting against acid rain. Car waxing provides a certain level of protection for the car's paint surface and also reduces the amount of water droplets adhering to the body, with very noticeable effects; 2. Another function is to prevent damage from high temperatures and strong UV radiation, as temperatures rise with changing weather conditions; 3. During driving, high temperatures can cause the car's paint to age. At this point, waxing serves to reflect light, slowing down the aging process of the paint.

What does the inspection validity period mean?

The inspection validity period refers to the valid period of the driver's license inspection. The inspection validity period on the driver's license indicates the valid duration for which the license can be used. For a first-time issued driver's license, the validity period is 6 years. For example, if the initial date of the driver's license is December 5, 2012, with a validity period of 6 years, the license will expire on December 5, 2018. Below are the required documents for driver's license inspection: 1. Identification: Resident ID card (a temporary residence permit is also required for those holding ID cards from other provinces or cities) and a copy. 2. Original driver's license: The original motor vehicle driver's license and the currently held driver's license. 3. Photos: Three recent 1-inch color photos with a white background. 4. Medical report: A qualified medical examination report from a district or county-level hospital or above. Such hospitals usually have medical examination points near the vehicle management office or traffic police station. 5. Application form: The applicant should obtain the "Motor Vehicle Driver's License Application Form" from the vehicle management office and fill it out according to the instructions.

Can You Turn Left on a Straight Green Light?

Whether you can turn left on a straight green light depends on the situation. Situations where turning is allowed: At an intersection with standard three-color traffic lights, you can turn left on a green light, but you must yield to oncoming straight-moving vehicles. Situations where turning is not allowed: When encountering lane-specific arrow signals, if the straight arrow is green but the left-turn arrow is red, you cannot turn left, but you may enter the left-turn waiting area. Vehicles in the left-turn lane can proceed when the left arrow turns green. Relevant regulations are as follows: Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" (State Council Order No. 405) states: For motor vehicle and non-motor vehicle signal lights, when the yellow light is on, vehicles that have already crossed the stop line may continue to proceed; when the green light is on, vehicles are permitted to proceed, but turning vehicles must not impede the passage of straight-moving vehicles or pedestrians. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crosswalk signals, non-motor vehicles and pedestrians should follow the motor vehicle signal lights. When the red light is on, right-turning vehicles may proceed if they do not impede the passage of other vehicles or pedestrians.

How to Solve the Abnormal Noise When the Rear Wheels Go Over Speed Bumps?

The main causes and solutions for abnormal noise when the rear wheels go over speed bumps are: 1. Spring aging. When a car has been used for too many years, the springs may age, causing noise when the car passes over bumpy roads. This is a normal phenomenon, and the solution is to replace the aged springs promptly. 2. Damaged shock absorber. When the plane bearing of the car's shock absorber is damaged, it can also cause noise when the car passes over speed bumps. This situation requires a professional at a repair shop or 4S store to inspect and repair the car's shock absorber. 3. Tire bulging. If the tire has bulges or the tire pressure is too high, it can also cause noise when the car passes over bumpy roads. In this case, the car's tires need to be inspected and repaired. 4. Severely worn brake pads. When the car's brake pads are severely worn, they can also cause noise during braking or driving. In this case, the brake pads should be replaced immediately. 5. Loose exhaust pipe. If the noise is caused by a loose exhaust pipe, simply re-secure the exhaust pipe.
