How to use cruise control?

Constant speed endurance system basically consists of on/off key, cancel key, SET current speed (set) and reset set speed (RES). When you need to use the cruise control function, turn on the system, press the on/off button or push the control lever, and the cruise control indicator light on the dashboard will light up. Then step on the accelerator to increase the speed to the speed you want, press the SET key, and the speed will be set at the current speed. After that, you can fine-tune the speed by pressing "RES" and "SET-" to realize the speed increase and decrease.
