What is the SET function in a car?
3 Answers
The SET function in a car is the speed setting switch for cruise control. It is the cruise speed control indicator. To set the cruise speed, accelerate the car to the desired speed and press the SET button. Additional Information: 1. Usage: To use cruise control, first press the [ON] button to activate the cruise control function. 2. Setting: To set the cruise speed, accelerate the car to the desired speed and press the [SET] button. Typically, the car speed should be greater than 30 miles per hour (approximately 48 kilometers per hour). When using cruise control, pressing the brake pedal will deactivate the cruise control function. 3. Resumption: Press the [RSM] button to resume the cruise control function. The speed will return to the previously set standard. While using cruise control, pressing the [ACCEL] button will increase the cruise speed. Pressing the [CST] button will decrease the cruise speed.
As a car owner, I frequently use the cruise control function and found that the SET button is the key to setting the cruising speed. I remember the first time driving on the highway, feeling a bit nervous, when a friend told me to first accelerate to the desired speed, say 100 km/h, then gently press the SET button on the steering wheel, and the car would maintain that speed on its own, freeing my foot from constantly pressing the accelerator. This is especially great for long-distance driving, reducing fatigue and allowing better focus. To slow down or stop, simply pressing the brake automatically cancels it. However, it only works well on smooth roads and shouldn’t be relied upon in city driving. After using it multiple times, I find it super effortless, more fuel-efficient, and much more comfortable, especially in hot summer weather. But it’s important to remember that it’s not autonomous driving—manual intervention is necessary when traffic conditions change, with safety as the priority. Every time I use it, I double-check the button position to avoid accidental presses.
I've been driving long distances for many years, and the SET function is like a daily assistant to me. It's usually located on the steering wheel, and with just a press, it locks the current speed for cruising. For example, when the highway is clear, I accelerate to 120 mph and press the SET button, and the car maintains that speed steadily without the need for frequent throttle adjustments. This allows me to briefly rest my feet, take a sip of water, or move my wrists, making driving more comfortable and safer. Canceling it is also simple—just hit the brakes or press the cancel button. What I enjoy most is using it on straight stretches of road, as it reduces the discomfort of foot fatigue and back pain. However, it's important to avoid using SET on curves or in heavy traffic to prevent delayed responses. Overall, this feature enhances driving efficiency and can even help save a bit on fuel costs. I recommend practicing a few times to get comfortable with it before using it frequently.
