What does cnl on the bus mean?

The cnl on the car cancels the cruise control operation and is generally set on the steering wheel of the car. Constant speed means constant speed, that is, after setting the speed you want to keep, the vehicle will always keep driving at the set speed, and the driver does not need to step on the accelerator. When driving on the highway for a long time, the driver can turn on the constant speed cruise function without controlling the accelerator pedal, which can effectively reduce fatigue and unnecessary speed change to save fuel. If you are driving on a road with heavy traffic, complex environment or too many vehicles, do not try to use the cruise control function. Cruise is prohibited in rainy and snowy weather.
