What Causes the Abnormal Noise When Reversing?

Possible causes include incomplete retraction of the brake pads, looseness in the driveshaft CV joint, or abnormal wear of internal transmission components. It could also be due to particles detaching from the surface of the brake pads, which accumulate on one side of the pad as the brake disc rotates. Below is a detailed explanation of abnormal noises during reversing: 1. The noise during reversing is actually a normal backlash sound. Since the vehicle is moving in the opposite direction, there is a certain gap between the brake pad and the rear end of the bracket. When braking, the brake pad impacts the rear surface of the bracket, producing a clunking noise. This is normal and not a cause for concern. However, if abnormal noises occur, it's important to promptly visit a 4S shop for inspection and repair. 2. Related to torque. Due to the principle of physical torque, the friction pressure at the front and rear ends of the brake pad differs. The front-end pressure is generally significantly lower than the rear-end, which is why in some "multi-piston" caliper products, the pistons closer to the front end of the friction surface are smaller. This torque causes the brake pads to develop a slight difference in thickness between the front and rear ends after wear, meaning a certain degree of uneven wear has occurred. When you suddenly reverse, this balanced uneven wear is abruptly "twisted," leading to abrupt brake engagement during reverse braking and accompanied by squealing noises due to torque imbalance.

How Long Until a Private Car is Mandatorily Scrapped?

For domestic 5-seat sedans and 7-seat SUVs, as well as non-commercial small and micro vehicles, there is no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the vehicle to be scrapped. Apart from the above-mentioned vehicles, small and micro non-commercial passenger vehicles, large non-commercial cars, and wheeled special machinery vehicles also have no usage period limit. Commercial vehicles have scrapping periods, as follows: Small and micro taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles have a scrapping period of 10 years, and large taxi passenger vehicles have a scrapping period of 12 years. Public bus passenger vehicles have a scrapping period of 13 years, other small and micro commercial passenger vehicles have a scrapping period of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping period of 15 years. Micro commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form" in duplicate and stamp the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, after inspection and verification by the motor vehicle inspection office, if they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection office for verification and signature. The license plates and certificates will be reclaimed, and the scrapping registration will be processed according to regulations. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of a motor vehicle's registration, the original owner can apply to use the original license plate number when registering a newly purchased motor vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation of registration; (2) The owner must have owned the original vehicle for more than three years.

What is Running a Red Light?

Running a red light refers to the act of a motor vehicle violating the prohibition of passage during the red light phase at a signal-controlled intersection or road section, crossing the stop line and continuing to drive. This is determined by capturing three photos via electronic cameras: a photo of the vehicle crossing the stop line at the intersection, including the traffic light showing red and the license plate number; a photo of the vehicle completely crossing the stop line, including the traffic light showing red and the license plate number; and a photo showing the vehicle continuing to move, with the traffic light showing red and the license plate number. If these three photos are captured, the vehicle can be determined to have run a red light. According to the "Road Traffic Safety Law," the act of running a red light is clearly defined. Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light indicates permission to proceed, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and if a vehicle passes through an intersection during a red light, it constitutes the traffic violation of running a red light. Here are some tips to avoid running a red light: Check the arrow light first, then the circular light: Currently, there are two types of traffic lights: arrow traffic lights and circular traffic lights. When arrow lights are present, drivers should first observe the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, right turns are permitted. However, if the right-turn arrow is red, right turns are prohibited, and violating this will be penalized as running a red light. Brake in time: When the red light turns on, ensure the front of the vehicle does not cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture it, resulting in a penalty for running a red light. If the front wheels have just crossed the stop line when the light turns red, the vehicle must wait for the green light before proceeding. Check the countdown of the green light before proceeding: When the green light flashes, if there is a countdown, drivers can judge accordingly. If there is no countdown, and the vehicle is close to the intersection with sufficient speed, it may proceed to avoid running a red light due to untimely braking. If the speed is slow and the vehicle is far from the intersection, brake immediately to avoid running a red light. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states the following for motor vehicle and non-motor vehicle traffic signals: 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 yellow light is on, vehicles that have already crossed the stop line may continue to proceed. 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 traffic signals. When the red light is on, right-turning vehicles may proceed if they do not impede the passage of other vehicles or pedestrians. Running a red light is not considered illegal under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If captured by surveillance cameras while yielding, the act of running a red light will not be recorded during manual review. Even if recorded, drivers can apply for reconsideration at the traffic police department. Extreme weather: When visibility is extremely low, and even electronic police cannot clearly see the traffic lights. Photos of violations may be blurry, and accidental red-light running will not be penalized. Emergencies: When transporting a critically ill patient to the hospital, multiple red lights may be run. In such cases, after delivering the patient, the driver can provide proof from the hospital or the rescued individual to the traffic police for verification. If confirmed, the violation records can be cleared. If possible, calling an ambulance is recommended to avoid accidents caused by running red lights. Traffic police direction: During peak hours, traffic police may temporarily direct traffic at key intersections. Drivers should follow the gestures of the traffic police.

How much engine oil should be added to the Roewe RX5?

Roewe RX5 oil filling is as follows: 1. The 1.5T model requires 5.5L; 2. The 2.0T model requires 6L when drained completely. 3. However, due to wear between the engine gears, it is best to buy a little more for daily top-ups. Here are some relevant details: 1. The Roewe RX5 uses 0W-30 fully synthetic oil. Because the vehicle operates with a turbocharger, the engine runs at high temperatures and speeds, so it has higher requirements for oil lubrication. The oil used must be genuine. If counterfeit or substandard oil is used, it will not only fail to protect the engine, lubricate the gears, and reduce wear, but it may also damage the engine and shorten the vehicle's lifespan. 2. Generally, with fully synthetic oil, maintenance is required once a year or every 10,000 kilometers.
