What to Do with ETC When Selling a Car?

If you sell your car but keep the original license plate number, you can remove the ETC device from the original car, reactivate it once, and then install it in the new car for continued use. If you no longer need the license plate number, the original ETC must be canceled. To cancel the ETC, you need to bring the vehicle registration certificate, driver's license, ID card, ETC pass card, and the bank card used for ETC. The ETC installation process is as follows: Upon receiving the device, first check whether the ETC card and electronic tag (OBU) are damaged. Press the anti-tamper button on the back of the OBU, and the red light will briefly turn on. The OLED screen will display "Tag Invalid, Please Insert Card," indicating the device is functioning normally. Clean the front windshield to ensure the glass surface is smooth, clean, and dry. Then peel off the protective film on the back of the OBU adhesive and stick it to the installation position. Press firmly for 2-3 minutes to remove any air bubbles. Insert the ETC card with the front facing the driver and the back facing the windshield. The chip should be inserted into the OBU device. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, as vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Cost-saving: Reduces expenses, decreases the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on toll fees; Improved efficiency: The ETC lane can theoretically increase vehicle passing efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What does PCV mean on a car?

PCV on a car stands for Positive Crankcase Ventilation. Here is an introduction to PCV: 1. Introduction: The PCV valve, or Positive Crankcase Ventilation, means the active ventilation control system for the crankcase (or oil pan) in Chinese. It is a metering control valve installed between the engine crankcase ventilation system and the intake system. 2. Components: The PCV system mainly consists of ventilation hoses and the PCV valve. Typically, one ventilation hose connects the air cleaner to the valve cover, while another connects the PCV valve to the intake manifold. The PCV valve is composed of a plunger-type valve and a spring, located on one side of the intake manifold. The vacuum level in the intake manifold determines the opening and closing of the PCV valve, as well as the degree of opening, which in turn determines the amount of blow-by gases that are re-introduced into the intake manifold for combustion. 3. Function: Its main role is to direct gases from the crankcase into the intake manifold via the PCV valve, with a small amount of air entering the intake manifold directly from the air cleaner through the PCV valve. This prevents issues such as icing at the throttle, incomplete combustion, and worsened emissions, while also preventing blow-by gases from entering the atmosphere and keeping the engine oil from deteriorating.

What is the original engine oil model for Geely Boyue?

Geely Boyue's original engine oil model is 5W-40, and the official use is Shell's semi-synthetic oil. If you need to change the oil during later maintenance, you can choose brands such as Mobil, Shell, Castrol, or Total. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high-temperature conditions. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the value, the better it can maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Geely Boyue is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover, generally filling about three-quarters of the oil bottle; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check if the engine oil level is within the standard range.

Can I Reschedule the Exam on the Same Day If I Fail the Subject 1 Test?

You need to wait 10 days before rescheduling the exam. According to the "Regulations on the Application and Use of Motor Vehicle Driving Licenses," you can take the Subject 1 make-up exam twice on the same day. If you fail the first attempt, you can take a second free make-up exam. If you fail the second attempt, the Subject 1 exam will be terminated. Subject 1, also known as the theoretical driving test or driver's theory exam, is part of the motor vehicle driving license assessment. The test content includes driving theory basics, road safety laws and regulations, local regulations, and related knowledge. The exam is computer-based and has a time limit of 45 minutes. A passing score for Subject 1 is 90 out of 100, with 100 questions consisting of single-choice and true/false questions, each worth 1 point. If you answer 11 questions incorrectly, the system will automatically submit the exam and end the test. Subject 1 Exam Content: Driving 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 Notes: During the exam, candidates should dress appropriately—no slippers are allowed. Electronic devices and bags are prohibited 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 lockers before entering the exam room. Upon entering, the identity verification desk will assign a seat. Once seated, begin the exam, ensuring the camera is aligned with you and adhering to exam discipline. If you fail the first attempt, you can take a make-up exam 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. A missing signature will invalidate the result. There is no limit to the number of times you can reschedule the Subject 1 exam. Each subject exam allows one retake if you fail. If you skip the retake or fail it, the exam is terminated, and you must reschedule. For Subject 2 and Subject 3, you only have five exam attempts, and rescheduling must be done 10 days later. If you fail the Subject 3 safe driving knowledge test, your previously passed road driving skills test results remain valid. The driving test consists of three subjects: Subject 1, Subject 2, and Subject 3. Subject 1 covers road traffic safety laws, regulations, and related knowledge; Subject 2 is the field driving skills test; Subject 3 includes two parts: road driving skills and safe driving knowledge. The safe driving knowledge test is conducted after Subject 3, so it is commonly referred to as Subject 4, although the official term (under the Ministry of Public Security’s Order No. 123) does not include "Subject 4."
