What is the function of the button next to the start button in BMW X4?
2 Answers
The button next to the start button in BMW X4 is the engine auto start-stop switch. The auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving (such as at traffic lights), and automatically restarts the engine when it's time to move forward again. The BMW X4 features a double-joint spring strut front axle for the front suspension and a five-link rear suspension. It is equipped with a 2.0T turbocharged engine delivering maximum power of 184PS (135kW) and peak torque of 290Nm, paired with an 8-speed automatic transmission.
I often drive my friend's BMW X4 and am very familiar with the function of that button. It's the driving mode switch key – with just a light press, you can toggle between Comfort, Sport, or Eco mode. Driving in Comfort mode is very smooth, perfect for city traffic jams; in Sport mode, the throttle response is as quick as a race car, especially powerful for highway overtaking; Eco mode reduces fuel consumption, saving gas without compromising performance. Using this button eliminates the need to navigate through menus, making it convenient and safe, particularly during long-distance drives – you'll notice completely different engine sounds and suspension feel after switching. I recommend trying different modes in various scenarios to experience BMW's intelligent driving pleasure. During regular car maintenance, remember to clean the button area to prevent dust buildup from affecting its functionality.
