Here are a few points to note:

Question 1: I tried briefly pressing it, but the instrument prompt disappeared. What should I do?

Reply: In this case, you should first shut down the vehicle, wait for about 1 minute, and then restart it. In this way, the instrument panel will display a prompt again, and you can try long pressing the operation again.

Question 2: After short pressing, I tried long pressing for more than 3 seconds. Is this operation effective?

Response: Invalid. It is necessary to ensure that when the instrument prompt appears, the operation of long pressing for more than 3 seconds is performed in order to successfully trigger manual regeneration.

Question 3: I have long pressed as required, but there has been no response. What could be the reason for this?

Answer: This may be due to several reasons. For example, the water temperature may not have reached the required level, at which point you need to increase the water temperature before proceeding with the operation. In addition, it may also be a problem with the clutch switch or brake switch, which requires you to take the vehicle to a service station for inspection and repair.

Question 4: My engine speed has automatically increased to 2000 rpm, but the regeneration process was interrupted shortly after, and the soot value did not decrease. What's going on?

Answer: This may be due to various reasons. For example, stepping on the brake, accelerator, or clutch pedal during the regeneration process may cause the regeneration to be interrupted. Another possible reason is that the regeneration temperature is difficult to increase, leading to regeneration failure. This situation also requires you to take the vehicle to a service station for inspection and repair.
