What are the two buttons on the BMW 740 steering wheel?

The two buttons on the BMW 740 steering wheel are used for shifting gears, with the left one for downshifting and the right one for upshifting, which is the manual mode. Introduction to the steering wheel: The steering wheel is a wheel-shaped device used to control the direction of vehicles such as cars, ships, and airplanes. Its function is to convert the force applied by the driver to the edge of the steering wheel into torque and then transmit it to the steering shaft. Function of the steering wheel: The steering wheel is generally connected to the steering shaft via splines. Using a larger-diameter steering wheel reduces the hand force required by the driver when turning. The steering intermediate shaft serves as a connecting component between the steering gear and the steering shaft, facilitating the standardization of the steering gear, compensating for errors during manufacturing and installation, and ensuring a more rational installation of the steering gear and steering wheel in the vehicle.

The two buttons on the steering wheel of my BMW 740 are features I use frequently while driving. The one on the left is the volume control button, which allows me to adjust the music volume up or down. A single press mutes the sound, making it especially convenient for operating the audio system effortlessly on the highway without reaching for the central console. The other button on the right is for voice control. With a simple press, I can summon the car's assistant and give commands like navigating to a destination or calling someone, which helps avoid distractions and enhances driving safety. Having driven this car for nearly two years, I find these small features thoughtfully designed for user convenience, particularly during long-distance drives. They significantly smooth out the driving experience and also connect seamlessly with Bluetooth for hands-free calls, preventing any frantic moments. Overall, BMW's attention to detail is truly considerate.

I've studied the steering wheel button design of the BMW 740. The two core buttons consist of a volume control knob integrated on the left side, which adjusts audio output by sliding up and down, and a smart voice activation button on the right that activates the vehicle's system when pressed, supporting natural language recognition for tasks like setting destinations or playing music. These buttons are connected to a micro-control unit in the circuit, ensuring swift and reliable response. Through multiple tests, I found the buttons offer comfortable tactile feedback with reasonable damping settings, minimizing accidental presses. Moreover, these buttons are compatible with BMW's driving assistance package, allowing adjustments to following distance settings even in cruise control mode, enhancing overall driving efficiency and safety. The engineering considers daily usage scenarios, making technology serve driving comfort.

I got familiar with the buttons on the BMW 740's steering wheel while driving this car. The one on the left is used to adjust the volume up and down, and it feels great to press; the one on the right is the voice command button, which allows you to speak and command the car to perform tasks like navigation or making calls. Years of experience have taught me that these functions are highly beneficial for driving, especially in congested city traffic where you don't need to distract yourself by tapping on the screen. Keeping it simple and user-friendly.
