How to Use the BMW 7 Series Chassis Lift?
3 Answers
After starting the vehicle, the car is in the middle position, and the lift button is in an off state at this time. Manually press the lift button, and the button will become constantly lit. At this time, the vehicle will be raised by 20mm, improving the vehicle's passability. It should be noted that if you need to lift the car with a jack, it is best to lock the air suspension in advance by pressing and holding the body lift button for seven seconds.
I often use the air suspension feature on my BMW 7 Series, and it feels particularly practical. The operation is quite straightforward—there's a dedicated lift button on the center console while seated in the driver's seat, or you can also select it via the iDrive screen. A single press raises the vehicle height to avoid scraping the undercarriage over speed bumps; lowering it is ideal for highway driving, enhancing stability. I prefer operating it when stationary or at low speeds, such as raising it when entering or exiting parking lots to prevent hitting obstacles. While driving, the system automatically adjusts the height, but manual adjustments at high speeds are not recommended for safety reasons. I regularly service and inspect the suspension system to prevent air leaks. This feature significantly improves daily driving comfort, especially on rough urban roads, reducing bumps noticeably. If the button responds slowly, it might indicate battery or sensor issues, requiring prompt repair. Overall, it's a great feature, but moderate use can extend its lifespan.
Controlling the BMW 7 Series' chassis lift isn't difficult, as there are buttons near both the center console and steering wheel that allow you to adjust it with a simple press. I prefer manual operation at low speeds, such as raising the body when driving over potholes to protect the chassis, or lowering it on smooth highways to enhance stability. The system supports an automatic mode that adjusts the height based on speed, but manual control offers a greater sense of command. The key requirement is to perform adjustments when parked or moving slowly—avoid making changes while driving at higher speeds, as this can cause instability. Different driving modes, like Sport and Comfort, indirectly affect the suspension height settings, so it's worth experimenting to find the right feel. I've noticed this feature wears out relatively quickly, so during annual maintenance, have the technician check the air pump and tubing to minimize malfunctions. Over time, learning some maintenance tips and avoiding frequent height adjustments can make the ride smoother.
