"+" and "-" can control the speed of cruise control, with "+" for acceleration and "-" for deceleration. The distance for cruise control is activated via the distance adjustment button, and then set using "+" and "-". The autonomous driving system mainly includes the lane keeping system and adaptive cruise control. With the support of the lane keeping system, cruise control becomes more reliable.

I often use the cruise control in my 3 Series while driving, and it feels very effortless. After getting in the car and starting the engine, first accelerate to your desired speed, such as the speed limit of 80 or 100 km/h on the highway. Then, you'll usually see a button with an arrow on the steering wheel—press the SET button to activate cruise control, and a small icon will appear on the dashboard. If you want to adjust the speed slower or faster, just use the up and down buttons. It's very convenient to use, especially during long trips, giving your legs a break. In case of any situation, stepping on the brake or clutch will automatically pause the cruise control, and you can resume it by pressing the RES button. Remember to use it less in heavy traffic or rainy weather to ensure safety first. The overall operation is very intuitive, and you'll get the hang of it after trying a few times.

I'm used to frequently using the cruise control system on highways, and the operation is quite effortless. The first step is to start the engine, drive to the target speed, then locate the cruise control button area on the left side of the steering wheel, usually a circular button. Press the SET button once, and the system locks the current speed, with a green indicator lighting up on the screen. To fine-tune the speed, use the up and down buttons to increase or decrease it. In case of emergencies, pressing the accelerator to speed up or braking can temporarily deactivate it, and then press the RES button to resume. Related advice is to check the button sensitivity during regular vehicle to avoid accidental touches. Avoid using cruise control in heavy traffic to prevent rear-end collision risks. The BMW 3 Series responds quickly, and driving it helps reduce fatigue.

My driving experience tells me that the cruise control operation of the 3 Series is very simple. After starting the car and accelerating to the desired speed, press the SET button on the steering wheel to activate it. After that, you can adjust the speed using the up and down buttons. The system automatically pauses when you press the brake. To resume the original speed, press RES. I often use it on long-distance roads to save energy.

I drive a 3 Series to commute, with cruise control being the main feature. The basic steps are: start the ignition, accelerate to the desired speed such as 60 km/h, press the SET button to activate it, and a cruise indicator will appear on the dashboard. Use the directional buttons to adjust the speed. Stepping on the brake or clutch will deactivate it, and pressing the RES button will restart it. Relatedly, this system relies on electronic sensors to control the throttle, avoiding speeding tickets. During maintenance, clean the button area to prevent sticking. The overall maintenance cost is low, but beginners are advised to practice on open roads first.

In daily driving, I find the cruise control on the 3 Series very user-friendly. The steps are clear: start the car, reach the desired speed, and press the SET button to activate—the car then maintains speed automatically. Adjustments are made via the speed increase or decrease buttons. In emergencies, braking pauses the system, which can be resumed with the RES button. I particularly enjoy using it during weekend getaways for fuel efficiency and comfort. However, it's important to avoid using it in congested urban areas as it can reduce responsiveness. BMW's system is quick to react, adding convenience to the journey.
