Where is the chassis lifting function located on the BMW 740?

The chassis lifting button for the BMW 7 Series is located on the central console, to the left rear of the gear shift lever. The button is marked with a small car icon featuring upward and downward arrows. To use it, start the vehicle and keep the gear in P (Park). Press and hold the lifting button, and the chassis will begin to rise. Release the button once the vehicle reaches the desired height. Principle of car chassis lifting: The car is equipped with body height sensors. The hydraulic suspension control unit collects data through these sensors (or a manual adjustment switch in the cabin) and the vehicle speed, then issues commands to raise or lower the chassis. Four electromagnetic valves inject hydraulic oil into the four shock absorbers respectively, enabling adjustable body height. The faster the vehicle speed, the lower the ground clearance of the chassis. Functions of car chassis lifting: Raising the chassis can appropriately improve the vehicle's off-road capability (including overcoming obstacles and shallow water), making it a relatively practical feature. Lowering the chassis reduces the vehicle's drag coefficient (slightly improving fuel efficiency). Additionally, lowering the chassis shortens the suspension travel, providing better lateral support and enhancing the vehicle's road performance (reducing the risk of rollover).
When I drive my BMW 740, the chassis lifting function is located on a dedicated button near the central armrest in the cockpit, usually a switch with an arrow symbol or integrated into the driving mode selector. Every time I get in the car, I use it to adjust the height to suit different road conditions: for example, raising the chassis on uneven roads to avoid scraping the undercarriage, or lowering it on highways to improve stability. I remember the maintenance manual mentioning that the button is surrounded by air conditioning and entertainment system controls, and operation is simple—just press it. If you can’t find it, you can access the suspension settings option via the iDrive menu on the central screen. This feature is super practical, especially when I frequently carry passengers in and out of steep driveways—one-touch lifting is effortless and convenient. Additionally, BMW engineers designed it quite thoughtfully, with the button positioned ergonomically to prevent accidental presses, but it’s advised to avoid getting water in it during cleaning to prevent short circuits. In short, it makes the driving experience more comfortable and safe, so don’t overlook routine maintenance.
As an ordinary person frequently exposed to luxury cars, I've noticed that the BMW 740's air suspension control is located on the center console to the right of the steering wheel, specifically around the circular driving mode selector or in a dedicated button cluster. I've developed the habit of adjusting it before driving based on conditions - raising it slightly for uneven urban roads during traffic congestion, or lowering it for reduced aerodynamic drag on long trips. The placement is ergonomically sound, allowing smooth operation near hand position to prevent distracted driving. BMW's system automatically remembers the last setting, with seamless height transitions that eliminate jolts. Interestingly, I've heard older models used physical buttons, while the new 740 might integrate this into the touchscreen with swipe controls, though maintaining identical operation logic. This feature isn't just about convenience - it protects the suspension system and extends its lifespan. Regular checks of button responsiveness are recommended to prevent electrical faults. In summary, locating this control properly makes tackling various road conditions effortless.
As an experienced driver of the BMW 740, I can confirm that the ride height adjustment function is typically located in the button cluster on the lower section of the center console near the driver's seat, with clear labeling for easy identification. It operates quickly and effectively, allowing you to raise the height at low speeds to navigate potholes or lower the vehicle for stable parking. The placement is ergonomic and doesn't obstruct your view. I recommend that new drivers familiarize themselves with the center console layout first to avoid pressing the wrong buttons.
