What does lift mode mean?

Luxury cars are generally equipped with a chassis lifting device, also known as air suspension. Typically, models equipped with air-adjustable suspension have ground clearance sensors near the front and rear wheels. Based on the output signals from these sensors, the vehicle's computer determines changes in body height and then controls the air compressor and exhaust valves to automatically compress or extend the springs, thereby reducing or increasing the chassis ground clearance to enhance high-speed stability or improve passability on rough terrain. Below are several states of air suspension: 1. Maintenance state: When the vehicle is lifted by a jack and leaves the ground, the air suspension system will close the relevant solenoid valves, and the computer will memorize the body height to maintain the original height after the vehicle is lowered. 2. Normal state: This refers to the engine running state. During driving, if the body height changes beyond a certain range, the air suspension system will adjust the body height at regular intervals. 3. Wake-up state: When the air suspension system is activated by the remote key, door switch, or trunk lid switch, the system will check the body height using the level sensors. If the body height is below the normal height by a certain degree, the air storage tank will provide pressure to raise the body to the normal height.
