China 4 OBD's exhaust emissions meet the China 5 emission standards, provided that the vehicle must be equipped with an OBD engine fault self-checking device to achieve the China 5 emission standard. Automobile emission standards refer to the regulations on the content of harmful gases such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), and PM (particulates, carbon smoke) emitted from vehicle exhaust. China 5 refers to the National Fifth Stage Motor Vehicle Pollutant Emission Standard, abbreviated as the "China 5 Standard". The emission control level of the China 5 Standard is equivalent to the European Union's currently implemented Euro 5 emission standard.

For not yielding to pedestrians at signal-controlled intersections and illegally honking, a fine will be imposed along with a deduction of 3 points. Typically, traffic police use mobile electronic monitoring devices. Once a traffic violation is captured, the data will be entered into the system, and the offender will be notified via SMS for processing. Below is additional information: Fines and point deductions: If caught by electronic monitoring systems for not yielding to pedestrians, you will receive a corresponding ticket notification, including a fine and point deduction. Vehicle violation information is generally received within 3~7 days or can be checked online.

What are the three situations where you turn the steering wheel half a circle back during right reverse parking?

There are three situations where you don't need to turn the steering wheel back to center during right reverse parking: when you see the right corner of the parking space entrance, when the right rear wheel enters the parking space, and when you don't need to turn the steering wheel back to center at all. When reversing, you need to shift into reverse gear and slowly reverse the car. When the lower edge of the left rearview mirror aligns with the control line, quickly turn the steering wheel all the way to the right. The key to turning the steering wheel half a circle back during reverse parking is to observe the right rearview mirror. When the car body covers the middle dashed line in front of the parking space, turn the steering wheel half a circle back to the left. The first situation: no need to turn the steering wheel back to center, keep turning all the way to the right until the car is parked, then turn the steering wheel back to center when the car body is straight. The second situation: after seeing the right corner of the parking space entrance and turning the steering wheel back to center, keep the steering wheel steady until the right rear wheel enters the parking space (which means the bumper enters the parking space, as long as it's within the entrance of the parking space, it's considered entering the parking space), then quickly turn the steering wheel all the way to the right, and turn the steering wheel back to center when the car body is straight. The third situation: similarly, keep the steering wheel steady until the right rear wheel enters the parking space (which means the bumper enters the parking space, as long as it's within the entrance of the parking space, it's considered entering the parking space), then quickly turn the steering wheel all the way to the right, and turn the steering wheel back to center when the car body is straight.

Can I Bring My Phone into the Car for Subject 2 Test?

You are not allowed to bring your phone into the car for the Subject 2 test, as the examiner may suspect cheating. Important notes for after entering the car during Subject 2: There is no time limit for starting after entering the car; first, close the car door and check if the door light turns off—this is crucial. Adjust the seatback to a 90-degree angle to your body and ensure it is stable by testing it forward and backward. Then, measure the height with your hand on your head to confirm it matches your usual practice height. If it's too low, use a seat cushion to adjust. Re-test the clutch: After fastening your seatbelt, re-test the clutch by pressing it all the way down with your left foot. Ensure your left leg has a slight bend to exert force; otherwise, readjust. Also, test the brake and accelerator to confirm everything is fine before starting the test.

What Causes Friction Noise Without Braking?

The reasons for friction noise without braking are as follows: Excessive wear of brake pads: The brake pads are too thin, exposing the metal, which causes the sensor on the brake pads to be worn out and trigger an alarm. Additionally, the friction between the metal of the brake pads and the brake disc can also produce noise. In this case, it is recommended to replace the brake pads and check whether the thickness of the brake disc meets the requirements. Sand or gravel between the brake disc and the brake pad: This situation usually occurs after the vehicle has driven through water, where mud or sand is brought into the gaps. When the brake pads and brake disc rub against each other, the temperature can reach 800-1200 degrees, making the brake pads very soft. Small stones can easily embed into the brake pads, causing sharp friction noises. Brake drag: Due to the brake piston not returning to its normal position after braking, the brake pads remain in a braking state, which can also produce certain abnormal noises during high-speed driving. Abnormal wear of the brake disc or brake pads: The brake disc may become deformed, damaged, dented, or raised due to external forces, while irregular wear of the brake pads can cause uneven surfaces, leading to friction noises even when braking.

What causes the headlights of the new 3 Series to not turn off?

Damaged headlight switch, open or short circuit in the headlight switch wiring, or incorrect signals from the light and rain sensor on the windshield can all cause the headlights of the new 3 Series to not turn off. Check if the lights are functioning properly: During driving, vibrations from the car body can cause the direction of the light beam to shift, affecting driving safety. Regularly inspect the lights to ensure their direction is correct and brightness is not diminished. If any issues are found, adjustments should be made promptly. Replace bulbs periodically: Car headlight bulbs should typically be replaced every 50,000 kilometers or approximately every 2 years. It is advisable to replace bulbs regularly. It is best to replace both bulbs simultaneously to avoid uneven brightness between the two sides. Additionally, when selecting bulbs, avoid inferior quality ones and choose those suitable for your vehicle model.
