On the vehicle license, those with BH at the beginning and ending with W or X are China 3, Y is China 4, and V is China 5 emission standards. Methods to check vehicle emission standards: 1. Look at the vehicle's environmental protection label: The back of the label has clear markings. However, the environmental protection label has now been canceled, meaning current vehicles no longer have this label. 2. Certificate of conformity: For new vehicles, you can check the vehicle's factory certificate of conformity or the vehicle conformity certificate. 3. Visit the Motor Vehicle Environmental Protection Website: You can log in to the public query platform of the Motor Vehicle Environmental Protection Website (click to jump to the query platform), enter the vehicle VIN number (Vehicle Identification Number) and the last 6 digits of the engine number to query vehicle information.

I've driven several China 5 standard vehicles, and finding the emission standard on the vehicle license isn't straightforward. The license mainly shows basic information like the vehicle brand, model, engine number, and chassis number, but the China 5 standard isn't directly stated as it's not a fixed emission label. To determine it, the most reliable method is to check the chassis number (VIN) through the traffic management department or some query apps. For example, you can visit the 'Ministry of Public Security Traffic Management' official website or use their WeChat mini-program to input the VIN, which will display the vehicle's environmental information, including whether it's China 5 or China 6. Additionally, the vehicle's registration date is a good reference—most China 5 models were registered around 2017. If the license happens to show a 'China V' mark, that's a rare printing error, so don't get your hopes up. If you can't find the info, it's best to visit a 4S shop and let a professional technician test it to avoid guessing wrong and affecting your annual inspection.

Why Can't the Haval H6 Bluetooth Connect to the Phone?

Haval H6 Bluetooth cannot connect to the phone due to reasons such as excessive distance. Below are the specific reasons for Bluetooth connection failure: 1. Bluetooth Invisibility: If the car Bluetooth or phone Bluetooth is in an invisible state, both devices will not be able to scan each other, making pairing impossible. The solution is to set the car Bluetooth or phone Bluetooth to a discoverable state. 2. Excessive Distance Between Bluetooth Devices: Since Bluetooth transmission has a limited range, when the phone Bluetooth and car Bluetooth are too far apart, the Bluetooth device may not be detected. Even if detected, the excessive distance may affect the connection. The solution is to bring the phone Bluetooth as close as possible to the car Bluetooth. 3. Hardware Issues: If the problem is due to hardware malfunction, it needs to be sent to a 4S shop for repair.

What is the reason for the anti-theft light flashing continuously after locking the car?

After locking the car, the anti-theft light flashing continuously is used to inform the owner that the vehicle's anti-theft system has been activated. The following is a detailed introduction to the reasons for the anti-theft light flashing continuously after locking the car: Working status: Indicates that the vehicle's anti-theft system is activated. Power consumption: If the car's engine anti-theft light flashes at a frequency of once every 1 to 2 seconds, it is normal. This means that the vehicle's engine has entered the anti-theft state, and the engine anti-theft system is functioning. This is a normal phenomenon, and the owner does not need to deactivate it. Moreover, the power consumption is minimal, and it poses no problem for the battery. If the battery is dead, the vehicle's anti-theft system will lock the vehicle, making it impossible to deactivate the anti-theft system via the remote control, open the doors, or start the engine. It will be necessary to use the mechanical key to unlock and either jump-start or replace the battery.
