At what speed can cruise control be set?
2 Answers
Cruise control can be set at 40 mph. Cruise control refers to automatically maintaining the vehicle speed without pressing the accelerator pedal, allowing the car to travel at a fixed speed. The method of using cruise control is: 1. When the vehicle speed is above 40 mph, press the CCS button on the left side of the steering wheel to activate it; 2. Use the RES and SET buttons to fine-tune the speed for acceleration or deceleration; 3. Press the brake or the CCS button on the left side of the steering wheel to deactivate it. The principle of cruise control is: The cruise control module compares the pulse signal from the speed sensor with the preset speed and issues commands to the servo mechanism to adjust the throttle opening, increasing or decreasing it to maintain the set speed.
When driving my own car, I noticed that the minimum speed for cruise control activation is generally between 25 to 30 mph, depending on the vehicle model. New car manuals often recommend setting it at 30 or 35 mph and above, as speeds too low can lead to instability. For instance, using it below 25 mph in urban areas feels impractical and increases distraction risks. I usually set it between 55 to 70 mph on highways, which is comfortable and fuel-efficient. On city roads, I occasionally use it but only activate it when traffic flow allows. Safety comes first—I always check the manual for the minimum speed setting with each new car to avoid incorrect setups causing issues. There are significant differences between brands: Japanese cars might start at 25 mph, while American or German models often require higher speeds. It's essential to test it on unobstructed roads to get a feel for it first.
