Tunnels do not allow overtaking or lane changing. Below are the precautions for driving in tunnels: Do not use high beams: Most tunnels nowadays are equipped with lighting facilities. Although the lighting may not be very bright, using low beams is sufficient for safe driving. Never use high beams because tunnels are inherently narrow, and encountering oncoming traffic can be stressful. High beams can instantly blind drivers of oncoming vehicles in such confined spaces. If an accident occurs in this small space, it could potentially lead to a complete traffic breakdown in the tunnel. Pay attention to light changes: When entering a tunnel, the surrounding space becomes darker, which typically causes the pupils to contract to adapt to the dark tunnel environment. After driving in the tunnel for an extended period, when approaching the exit, you may notice a bright white light at the exit, making it difficult to see anything. This requires a brief moment of adaptation. During this time, remain calm and continue driving normally. As long as you stay composed, accidents are unlikely to occur.

What does it mean when the EPC light is on in a car?

The EPC indicator light can illuminate in two states: during the power-on self-test and under other circumstances. The power-on self-test is an indication that the vehicle is checking the status of all sensors before driving. Generally, if the vehicle is not started after powering on, the light will turn off by itself after about 3 seconds. If the EPC light remains on after the vehicle starts or illuminates under other conditions, the main causes may include faults in the engine intake system, throttle body, fuel system, engine, ECU control unit, or brake lights. Below is a detailed explanation of the reasons for the EPC light illuminating under other circumstances: Engine intake system fault: The EPC light will activate if the engine intake is obstructed or insufficient. Throttle body fault: Carbon buildup is a common issue with the throttle body. Additionally, dirt accumulation can affect intake, triggering the indicator light. Fuel system fault: Examples include substandard fuel, deteriorated fuel, or poor fuel atomization. Engine fault: Insufficient engine pressure or issues with components like the intake valves in the powertrain can also cause the EPC light to illuminate. ECU control unit fault: This may occur due to interference with the vehicle's computer signals or false alarms from the computer. Brake light fault: Situations such as non-functioning brake lights, faulty brake switches, or brake circuit issues can trigger the EPC light. Solutions for when the car's EPC light is on: Troubleshoot the intake system, use fuel of the appropriate grade, and clean the throttle body. Remove carbon deposits from relevant components. Re-flash the ECU with the correct data. If the EPC light comes on, the owner can first try turning off the engine and restarting it to see if the light remains off. If it does not illuminate again, there may be no issue, and the light might have been affected temporarily. If the EPC light stays on or frequently illuminates, the vehicle should be taken to the nearest service center for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data in the system is abnormal, the EPC system will take predefined actions to address the powertrain issues. Common EPC indicator lights typically display two colors: yellow and red. A yellow EPC fault light indicates that the vehicle can still be driven, but it should proceed slowly to a repair point for inspection. A red EPC fault light signifies a more serious issue, and the vehicle should be pulled over immediately, with professional repair services contacted. Continuing to drive under such conditions can severely damage the vehicle's core components or compromise safety.

How often should a 6-seater new car undergo annual inspection?

Non-commercial 6-seater vehicles are exempt from inspection for the first six years, then inspected every two years from six to ten years. Vehicles over ten years old require annual inspection, and those over 15 years old must be inspected every six months. Commercial 6-seater vehicles must be inspected annually within the first five years, and every six months thereafter. Required documents for vehicle inspection include the vehicle's registration certificate, valid compulsory insurance policy, the owner's ID card, and all outstanding traffic violations must be cleared in advance. Additional notes: Trucks and large/medium non-commercial passenger vehicles must be inspected annually within the first ten years, and every six months thereafter. Motorcycles must be inspected every two years within the first four years, and annually thereafter. Vehicle inspection mainly includes the following items: Exterior inspection: Checks include vehicle lights, body appearance, suspension, sunroof, and tires. It verifies if the lights are functioning properly, if the body color has been changed, and if the suspension has been modified. Emission test: Checks if the vehicle's exhaust emissions meet national standards during high-speed operation. On-road test: Primarily checks the vehicle's braking system, headlights, horn, and chassis. Violation check: All outstanding traffic violations must be resolved before the vehicle can pass inspection. Vehicle inspection can be conducted up to 90 days in advance, but must not be overdue. According to Article 47, Paragraph 4 of the "Motor Vehicle Registration Management Regulations," vehicles that fail to undergo safety technical inspection within the specified period will be issued a warning or fined by the traffic management department. The inspection can only proceed after the fine is paid. Vehicles that fail to undergo inspection on time are not allowed on the road. Driving a vehicle without timely inspection results in 3 penalty points and a fine. If an uninspected vehicle is involved in a traffic accident, the owner bears full or primary liability, and insurance companies will not cover the damages. Driving without timely inspection is considered illegal and may result in vehicle impoundment.

What emission standard does IV correspond to?

IV corresponds to the China IV emission standard, which is the national fourth-stage motor vehicle pollutant emission standard. Vehicles meeting the China IV standard must reduce pollutants by an additional 30% to 50% compared to China III standards to comply. Automotive emissions refer to harmful gases such as CO, HCNOx, and PM discharged from exhaust. Technologies like improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices are applied to control and reduce vehicle emissions below specified limits. Any new compression-ignition vehicles failing to meet China IV standards cannot be registered.

Is VI China 6?

VI is China 6, V is China 5, and IV is China 4. China 6 means that the vehicle's emission standards meet the requirements specified in the sixth stage of the national emission standards. It is commonly referred to as China 6 emissions and is a national vehicle emission standard that has been gradually implemented since the end of 2019. Vehicle emission standards refer to regulations on the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, and particulate matter emitted from vehicle exhaust. The purpose of setting vehicle emission standards is to curb the production of these harmful gases, enabling automobile manufacturers to improve vehicle emission standards and reduce the generation of harmful gases.

What does the DS gear in an automatic transmission car mean?

Automatic transmission cars usually display DS gear as D/S, which means switching between D gear or S gear. D gear is the drive gear, and S gear represents the sport mode. The specific introduction is as follows: D gear: D gear is the drive gear, also known as the driving gear, which is the abbreviation of Drive. When the gear lever is moved into this position, the transmission automatically shifts gears within the engine speed range, and the shift point depends on the engine load, the driver's driving style, and the vehicle speed. S gear: S gear represents the sport mode. When this gear is engaged, the gear can be freely switched, but the shift timing is delayed, keeping the engine at high speed for a period of time to increase the car's power.
