What does SET mean on the Lavida car?

[McBrynlee]

SET on the Lavida car is a speed setting switch, which is a type of cruise control. Here are the precautions for using the cruise control system: 1. In principle, cruise control should be used on highways or fully enclosed roads. Because on non-enclosed roads, complex road conditions are not conducive to traffic safety. 2. It is prohibited in rainy weather and snowy or icy conditions. 3. It should be disabled on mountain roads or roads with too many curves. Under normal circumstances when exiting a curve, appropriate acceleration is needed to provide greater steering force. In cruise control mode, the vehicle automatically maintains a constant speed, with the throttle controlled by the onboard computer, which often poses a danger when driving on curved roads. Under such conditions, the speed should be appropriately controlled. 4. Cruise control is also not suitable when there are too many vehicles on the road.
