How to operate Roewe 550 cruise at fixed speed?

I am the owner of 550. Let me answer your question.

When driving, press the cruise button on the right side of the steering wheel. At this time, a green cruise standby light will light up on the dashboard. Cruise can only be activated when the vehicle speed is above 50KM/H, and then press the wheel when it reaches 50KM/H, remember to press it in and not roll. The green light will turn yellow. At this point, the constant speed cruise will begin. The car will move forward at a constant speed without stepping on the accelerator. During cruising, the cruising speed can be adjusted by the roller. Pressing the clutch or brake during cruising will make cruising stand by, and you need to press the steering wheel again to restart. When cruising, pressing the rightmost key on the steering wheel is to close the cruise.
