How to Activate the Lift Mode of Mercedes-Benz Air Suspension?

Press the CAR button on the MMI control panel, then press the SETUP button. The lift mode refers to the vehicle's computer using sensors at the bottom of the car to assess road conditions, thereby lowering or raising the chassis ground clearance to enhance high-speed stability or improve passability on rough terrain. During normal driving, the air suspension operates in the following scenarios: 1. Maintenance State: When the vehicle is set to lift mode, the air suspension solenoid valve closes, and the air suspension does not automatically adjust. 2. Normal State: This state typically occurs while the vehicle is in motion. During driving, sensors periodically send electrical signals to the controller, which adjusts the vehicle height based on these signals. 3. Wake State: When the vehicle is awakened by the key or other means, the air suspension automatically checks the ground clearance. If the clearance is below the standard, the air tank supplies pressure to restore the vehicle height. Additionally, the air suspension can provide a soft/hard adjustment mode.
Last time when I drove my friend's Mercedes-Benz for camping, I personally tested the air suspension lift mode. The operation is quite simple: first start the car, wait until the engine runs normally, then find the driving mode selection interface on the central control screen—usually in a button resembling a small house. After entering, select OFFROAD or off-road mode, and the system will automatically raise the suspension height. This feature is extremely practical, especially on bumpy roads or when crossing riverbeds, as it enhances chassis protection. Don't drive too fast; it's recommended to keep it under 50 mph to prevent body sway. After using it, I felt the car was more stable, but be aware that the suspension will automatically reset after parking and turning off the engine. Avoid keeping it raised for too long to prevent battery drain.
