Turn the switch on the left-hand small lever to the ON position to enter cruise control mode. In cruise control mode, when the vehicle reaches the desired speed (e.g., 120 km/h), press the speed setting switch "SET-" button to store the current driving speed and maintain that speed. More details are as follows: 1. The Cruise Control System (CCS), also known as the speed control system or autopilot system, is abbreviated as CCS. 2. Its function is to automatically maintain the vehicle speed as set by the driver without the need to press the accelerator pedal, allowing the vehicle to travel at a fixed speed. 3. With this system, drivers no longer need to control the accelerator pedal during long highway drives, reducing fatigue and unnecessary speed changes, which can save fuel. 4. It is recommended to keep the cruise control switch in the ON position for easy access to this function. After setting the speed, pressing the "+" or "-" button allows for fine-tuning the cruise speed in increments or decrements of 5 km/h.

When driving the Kia Lantra, the cruise control buttons are located on the right side of the steering wheel, typically featuring several buttons such as the 'SET' button for speed setting, the 'CANCEL' button to deactivate the function, and '+' and '-' for speed adjustment. I often use this feature during long highway drives as it automatically maintains the speed, giving my right foot a rest while saving fuel and effort. However, you must first accelerate to over 50 km/h before activating it; otherwise, pressing the buttons won’t work. Remember not to use it in urban areas or heavy traffic, as it can be distracting and lead to accidents. A quick tip: If the car suddenly accelerates abnormally, the buttons might be stuck and require a check-up at a 4S shop, since steering wheel buttons can wear out over time.

After driving the Elantra for just a few months, I quickly familiarized myself with the location of the cruise control switch. It's mainly positioned on the right side of the steering wheel, near the thumb. The button labeled 'SET' is for setting the current speed, 'CANCEL' is for temporary deactivation, and pressing 'RES' resumes the original speed. As a novice driver, I was cautious when first using it—I practiced several times on open roads: accelerate to over 60 km/h, press 'SET' to engage automatic cruising, and cancel it by pressing the button or stepping on the brake. The advantage is reduced fatigue on long drives and some fuel savings. However, don't rely on it too much, especially in rainy, foggy conditions or heavy traffic—always keep a firm grip on the steering wheel.

I think the cruise control design of the Langdong is quite user-friendly, with buttons conveniently located on the right side of the steering wheel, clearly marked as 'SET' and 'RES'. To operate, first accelerate to the desired speed and press 'SET'. For fine-tuning, use the '+/-' buttons. However, it sometimes works and sometimes doesn't, possibly due to poor button contact or wiring issues, so regular cleaning or inspection is necessary. For drivers who frequently drive on highways, it can reduce foot fatigue, but remember not to activate it in heavy traffic—staying alert is key. Safety first, don't press buttons randomly.
