ETC devices are divided into wired charging and solar panel charging types. Solar-powered ETC devices do not require charging, while wired charging ETC devices need to be charged using a charger. Both types of ETC electronic tags contain internal batteries. Solar-powered ETC devices do not require charging during daily driving, with their lithium batteries typically lasting 3 years under normal use. However, for infrequent ETC users, it is recommended to charge the ETC device every 3 months to effectively mitigate the impact of natural battery discharge on its lifespan. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If applying through an agent, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, a bank card for deducting highway tolls is needed. Applicants must be between 18 and 60 years old, and the vehicle must be registered under their name. How ETC works: The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane at toll stations. Using computer networking technology, it settles payments with the bank in the background, allowing vehicles to pass through highway or bridge toll stations without stopping to pay. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel by reducing noise, exhaust emissions, and pollution as vehicles pass through toll stations without stopping; Cost-effective: Reduces vehicle wear and fuel consumption by minimizing the frequency of starting and braking. Users can also enjoy toll discounts; Improved efficiency: ETC lanes can theoretically increase traffic efficiency by 2-3 times, making traditional ETC more advanced, faster, and higher-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

Why does the driver's license still show as pending on 12123 after the annual inspection?

After the annual inspection of the driver's license, it still shows as pending on 12123 because the staff have not yet entered the inspection information into the online system. As long as the inspection procedures are correct, it will not affect the use of the driver's license. Below are the details regarding the driver's license annual inspection: 1. Renewal time: According to the Road Traffic Safety Law implemented on May 1, the minimum validity period of a driver's license is 6 years, and the license does not require annual inspection during its validity period. However, the renewal should be processed at the local traffic police branch within 90 days before the expiration date. 2. Medical examination: Drivers aged 60 and above, regardless of the type of license they hold, must collect the "Motor Vehicle Driver's License Application Form" from the Vehicle Management Section of their local traffic police branch during the original annual inspection period. After undergoing a medical examination at a designated hospital, they must submit the form back to the Vehicle Management Section for computer confirmation.

What materials are needed for the first car maintenance?

The items required for the first maintenance include: driver's license; vehicle registration certificate; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle purchase invoice, and you need to go to the designated first maintenance institution for the service. Note: Make an appointment with the 4S store in advance. The first maintenance refers to the initial service after a new car is driven, and the specific time varies by car, usually after driving 1,000 to 3,000 kilometers. The car needs to participate in the first maintenance in time, neither in advance nor delayed. The completion of the first maintenance marks the end of the car's running-in period, and the car can now be driven according to the standard load and normal speed required by the vehicle. The time for the first insurance is calculated based on the date of picking up the car. There are two indicator values for the first maintenance time: mileage and time. Whichever comes first will be the standard. The first maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking whether various oil levels are normal, checking whether the generator belt and wiper blades are damaged, checking whether the tire pressure is normal, and checking whether the tires are damaged or bulging. Time required: It takes about 2 hours to complete all the work. The most important part of the first maintenance for a new car is changing the engine oil and oil filter. When changing the engine oil, the oil filter must be replaced together, and the selection of engine oil must refer to the "Vehicle Use and Maintenance Manual," as different models have different specified engine oil grades. Maintenance precautions: Do not wash the interior of the car body with water: Many people will tidy up and clean their cars during holidays, washing the body with water and wiping it with a cloth. Here, it is important to remind that the interior of the car body does not need to be washed directly with water. If the floor mats are dirty, you can use a vacuum cleaner or take them out, brush them with detergent, dry them, and then put them back. There are many through holes under the rubber mats on the floor of the driver's cab. If water enters, it will not dry but will flow through the holes to parts like the gearbox, causing erosion and corrosion. The better approach is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is insufficient, it is recommended to drain the antifreeze early and add the same brand of antifreeze from the beginning. Because different brands of antifreeze have different chemical functions, the various functional additives may corrode each other. Different brands of antifreeze use different additives, so do not mix them to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When the bolts on a running car rust, they are usually oiled to make them work properly again. To prevent the bolts and nuts on the wheels from rusting, some people apply lubricating oil to them, but this brings necessary risks to safe driving. When the car is driving at high speed, the bolts and nuts may loosen or even fall off, leading to driving failure. When promoting an EFI car, there is no need to step on the accelerator: The promoter of an EFI car is different from that of an ordinary car. Its fuel injection control device can actively adjust the fuel supply according to the temperature and working conditions of the promoter, making the promoter work smoothly.

What does actual driving experience mean?

Actual driving experience refers to the number of years a person has been driving a car. The details are as follows: 1. Definition: Driving experience is the period during which a motor vehicle driver has held a motor vehicle driving qualification, calculated from the date the driver obtained the driving qualification. If a motor vehicle driver obtains different driving qualifications by adding permitted vehicle types (additional driving qualifications), each driving qualification has its own separate driving experience, which should not be confused. 2. Calculation standard: If a driver's license is revoked for not being renewed on time or for not submitting a medical examination report within two years, the driver can regain the driving qualification by passing Subject One (the examination on road traffic safety laws, regulations, and related knowledge). After regaining the driving qualification, the original permitted vehicle types of the driver's license are retained, and the driver's previous driving experience is counted continuously.

Why does the manual gear lever not automatically return to the center position?

There are several reasons why the manual gear lever does not automatically return to the center position: 1. Interlock device: The grooves, locking pins, or steel balls of the interlock device are severely worn. Check the wear condition of the grooves, locking pins, and steel balls of the interlock device. If they are severely worn, they should be replaced promptly. 2. Lower end of the gear lever: The lower end of the gear lever is insufficient in length, the working surface at the lower end is excessively worn, or the fork causes excessive wear of the grooves. Inspect the fit between the length of the lower end of the gear lever and its working surface. If the wear is severe or the gap is too large, replacement is necessary. 3. Gear lever ball head: The positioning pin of the gear lever ball head is loose, broken, or the ball head and ball hole are excessively worn. Examine the positioning pin of the gear lever ball head. If it is loose, broken, or the ball head and ball hole are severely worn, they should be replaced immediately.

Can You Still Drive When the Partial Engine Power Loss Light Comes On?

Engine partial power loss light, also known as the engine malfunction indicator light, when illuminated, indicates that the vehicle's engine power is compromised or insufficient due to a certain fault. Whether you can continue driving depends on different scenarios. First scenario: If the engine malfunction light comes on and the car cannot start, it might be caused by a faulty fuel pump or ignition components. In this case, you should not continue driving and need immediate repairs. Second scenario: If the malfunction light is on but there are no noticeable driving abnormalities, it could be due to a sensor malfunction or a false alert. In such cases, you may continue driving temporarily, but for safety reasons, it's advisable to drive at low to medium speeds and promptly visit a nearby repair shop for inspection. Third scenario: If the engine malfunction light is on, the vehicle can still operate but exhibits severe shaking, lack of acceleration, or other symptoms, continuing to drive might worsen the fault, damage the engine, or trigger other issues. Therefore, it's not recommended to keep driving; instead, call for assistance and wait for support. Reasons for the engine partial power loss light illuminating: Carbon buildup issues: This includes carbon deposits in the cylinders, throttle body, spark plugs, and intake system—areas critical to engine power output. Excessive carbon buildup reduces ignition energy and intake efficiency, ultimately leading to decreased engine power and weak idling. Fuel system: Using incompatible fuel grades can reduce the car's output power and performance. Alternatively, blockages in the fuel tank vent, fuel tank switch, fuel filter, or fuel lines between the tank and carburetor can restrict fuel supply, resulting in a lean air-fuel mixture and poor engine acceleration. Air intake: Air is one of the engine's power sources. If the air filter is clogged due to prolonged use without cleaning, insufficient airflow can cause an overly rich air-fuel mixture, reducing engine power. For turbocharged vehicles, a malfunctioning turbocharger can also lead to decreased engine power. Engine overheating: Insufficient engine oil, low coolant levels, or faulty cooling systems can increase engine load and impair heat dissipation. Overheating reduces lubrication effectiveness, increases mechanical wear, lowers engine power, and raises fuel consumption.
