What is the tire model of the Corolla?

The Corolla has two tire specifications: 195/65R15 and 205/55R16. In 195/65R15, the first number 195 represents the tire width of 195MM, 65 indicates the aspect ratio of the tire section is 65%, meaning the section height is 65% of the width, and 15 represents the rim diameter of 15 inches. The letter "R" in the middle stands for radial tire. In 205/55R16, the first number 205 represents the tire width of 205MM, 55 indicates the aspect ratio of the tire section is 55%, meaning the section height is 55% of the width, and 16 represents the rim diameter of 16 inches. The letter "R" in the middle stands for radial tire. The Corolla's tire brand is Bridgestone, and the spare tire specification is non-full size. If you want to replace the tires yourself, you can follow the steps below: Take out the spare tire and jack, place the jack under the frame of the tire to be replaced, ensuring the jack touches the metal part of the frame; Raise the jack until it supports the car. The jack should be positioned under the vehicle. Check and ensure the jack is at a right angle to the ground; Remove the hubcap and loosen the nuts counterclockwise. Do not completely loosen the nuts, just enough to eliminate resistance. When loosening the nuts for the first time, keeping the tire on the ground ensures that the nuts turn rather than the tire; Turn the nuts counterclockwise until they come off. Repeat this step for all lug nuts and completely remove the nuts; Place the new tire on the hub, carefully aligning the tire rim with the wheel bolts. Install the lug nuts and tighten them by hand until all nuts are concealed. At this point, the tire replacement is complete. In addition to the model, the tire is also marked with the following common data: Tire cord material: Represented by Chinese pinyin, such as M-cotton cord, R-rayon cord, N-nylon cord, G-steel cord, ZG-steel radial cord tire. Speed rating: Indicates the maximum speed at which the tire can carry the specified load under specified conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Common speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h; Rim specification: Indicates the rim specification compatible with the tire for practical use, such as "Standard rim 5.00F".

What engine does Junma Auto use?

Junma Auto's engines are from the Airflow series, which utilize German Mahle technology. Among Junma Auto's models, the Junma S80 is equipped with the TNN4G15T engine, delivering a maximum power of 115kW and a maximum torque of 215Nm. For daily maintenance of the Atenza engine, the following methods can be employed: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements; Regularly replace the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine issues. To prevent faults, change the oil regularly based on usage conditions and maintain an appropriate oil level; When oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination; Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear; Regularly use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

Does the red light camera capture the front or the rear of the vehicle?

Both are captured. Electronic cameras take three photos to determine a red light violation: a photo of the vehicle crossing the stop line at the intersection, showing the red light and license plate number; a photo of the vehicle completely passing the stop line, showing the red light and license plate number; and a photo of the vehicle continuing to move, comparing the vehicle's position changes, showing the red light and license plate number. If these three photos are captured, the vehicle is determined to have run a red light. The act of running a red light is clearly defined in the "Road Traffic Safety Law." 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: First look at the arrow light, then the circular light: Currently, there are two types of traffic lights: arrow traffic lights and circular traffic lights. If an arrow light is present, first observe the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, a right turn is permitted; when encountering an arrow signal light with a red right-turn arrow, a right turn is prohibited. Otherwise, it will be penalized as running a red light. Brake in time: When the red light turns on, do not let the front of the vehicle 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, do not proceed through the intersection; wait for the green light before moving. Check the green light countdown before proceeding: When the green light flashes, if there is a countdown, use it to judge whether to proceed. If there is no countdown, and the vehicle is close to the intersection with high speed, it may proceed to avoid running a red light due to untimely braking. If the speed is low 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: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not obstruct 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-motorized vehicle or pedestrian signals, non-motorized vehicles and pedestrians should follow the motor vehicle signal. When the red light is on, right-turning vehicles may proceed if they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not considered illegal under the following circumstances: Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights, the evidence photos may be blurry. In such cases, mistakenly running a red light will not be penalized by traffic police. Emergency situations: When rushing a critically ill patient to the hospital, multiple red lights may be run, far exceeding the 12-point penalty limit. After delivering the patient, the driver can provide hospital or patient documentation to the traffic police for verification. If confirmed, the violation records will be cleared. If possible, calling an ambulance is recommended to avoid accidents caused by running red lights. Police direction: During peak hours, traffic police may temporarily direct traffic at key intersections. Drivers should follow the officers' hand signals. Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If a red light is run while yielding to such vehicles, manual review will not record the violation. Even if recorded, the driver can apply for a review at the traffic police department.

Is Compulsory Traffic Insurance Automatically Transferred During Vehicle Ownership Transfer?

If the compulsory traffic insurance purchased by the original vehicle owner follows the vehicle, it will be transferred to the new owner upon vehicle ownership transfer. If the compulsory traffic insurance does not follow the vehicle, the owners will need to go to the insurance company to complete the transfer procedures for the vehicle insurance. The owner needs to prepare the vehicle registration book, the new owner's driving license, copies of the new and old owners' ID cards, the invoice issued during the used car transaction, and the amendment application form provided by the insurance company to complete the transfer of compulsory traffic insurance. Important Notes Once a used car is purchased, promptly complete the transfer procedures for compulsory traffic insurance and other insurances. Otherwise, in the event of an accident, the beneficiary will be the original owner, and the new owner will not be able to receive compensation. Compulsory Traffic Insurance for Vehicles: The full name of compulsory traffic insurance is "Compulsory Motor Vehicle Traffic Accident Liability Insurance." It is a mandatory liability insurance where the insurance company compensates for personal injuries, deaths, and property losses of victims (excluding vehicle occupants and the insured) within the liability limits caused by road traffic accidents involving the insured vehicle. The premium is based on the nationally unified standard rates. However, the prices of compulsory traffic insurance vary for different vehicle types, mainly influenced by the number of car seats. Compared to the over 20 exemption clauses in commercial third-party insurance, compulsory traffic insurance covers a much broader range, including losses caused by intentional actions of the victim, the insured's own property losses, related arbitration and litigation costs, and some indirect losses caused by the accident. Moreover, regardless of whether the insured vehicle is at fault in the accident, compulsory traffic insurance will compensate within the liability limits without any deductible or exemption rate. Introduction to Electronic Insurance Policies An electronic insurance policy refers to an electronic policy issued by an insurance company using digital signature software and enterprise digital certificates that comply with the PKI system, bearing the electronic signature of the insurance company. An insurance policy, abbreviated as a policy, is the official written proof of the insurance contract between the insurer and the insured. The insurance policy must fully record the rights, obligations, and responsibilities of both parties to the insurance contract. The content recorded in the insurance policy serves as the basis for both parties to fulfill the contract. The insurance policy is proof of the establishment of the insurance contract. Advantages of Electronic Insurance Policies: Saves paper resources, eliminating the need to print insurance proof labels; Saves time and is convenient, not restricted by time or location, with information universally accessible online anytime, quickly and easily; Allows for reissuance and resending, eliminating worries about losing it. If a paper version is needed offline, it can also be printed or mailed; Facilitates management. After electronic unification, insurance companies and traffic police departments can more easily manage the insurance information of various vehicles.

How to Maintain a Used Car After Receiving It?

Replace the engine oil and oil filter (oil filter) The oil filter, fuel filter, air filter, and cabin air filter are commonly referred to as the "four filters" of a car. Although they may seem insignificant, they play a crucial role. The oil filter and fuel filter work to remove impurities from the oil and fuel, ensuring the engine runs smoothly. The air filter and cabin air filter also act as screens; without their filtration, even the best car won't go far, and the best air conditioning will emit unpleasant odors. When changing the oil, it's essential to replace the oil filter simultaneously to ensure the oil passages remain free of blockages. Of course, if upon inspection you find that these components were recently replaced, there's no need to change them again—save money where you can. Inspect and maintain the spark plugs Generally, spark plugs have a lifespan of 15,000 kilometers, while long-life spark plugs last no more than 50,000 kilometers. After a certain mileage, spark plugs can accumulate carbon deposits, and the electrode gap may widen. Carbon buildup increases engine fuel consumption, and a widened gap can make starting the engine difficult. When inspecting spark plugs, check the color of the burn and the electrode gap. Therefore, after purchasing a used car, it's important to inspect and maintain the spark plugs to ensure efficient ignition, prolong the engine's lifespan, and save fuel. Replace the timing belt and water pump If you've purchased a car that's over five years old or has exceeded 80,000 kilometers, the safest approach is to replace the engine timing belt, along with the water pump and auxiliary belts. Waiting until the water pump fails or the belt breaks can be dangerous. I once experienced this while driving a friend's car—the entire coolant leaked out, and I had to tow the car (costing me 2,000 yuan, which was heartbreaking). Note: Most used cars in the market are at least three years old, with many exceeding five years. Replace the transmission fluid Transmission fluid is essential for keeping the gear system clean but is often overlooked. After purchasing a used car, it's advisable to replace the transmission fluid with the manufacturer-specified type, especially for cars over five years old. Note: For cars older than five years or with over 80,000 kilometers, it's best to replace the transmission fluid. Clean the air conditioning system The car's air conditioning evaporator and blower are often enclosed in dark, damp conditions. Impurities, dust, bacteria, and viruses from the air can combine with condensation and clog components like the evaporator, accumulating dirt, nicotine, and mold. These contaminants breed quickly, producing foul odors that spread through the air conditioning, polluting the cabin and making passengers uncomfortable. Therefore, regardless of the car's age or mileage, cleaning the air conditioning system is a must after purchasing a used car—especially if the previous owner smoked inside the vehicle. Maintain the battery Check the battery's date or display status. If you notice the engine cranking weakly or the lights dimming, it's a sign the battery is nearing the end of its life and should be replaced as soon as possible. Car circuits are divided into low-voltage and high-voltage systems. When inspecting low-voltage components, check for burnt wires or poor connections, and also pay attention to the condition of the fuses. A battery typically lasts about two years, while spark plugs last up to 40,000 kilometers. Inspect the tires (traction) Some owners prioritize the car's appearance, so used cars may show little external wear. However, frequently used vehicles often have significant tire wear. When inspecting a used car, pay attention to the tread patterns and cleanliness of the tires, and ensure they have adequate traction. Some tires may look new or have deep treads, but the rubber may have hardened. Additionally, here's a tip: Most dealers replace severely worn tires on used cars they acquire, but the tires they use are usually the cheapest available!
