Locate the air suspension adjustment switch. This switch is usually located on the center console or dashboard.
Turn the switch to the desired setting. There are typically three settings: Low, Normal, and High.
The air suspension will automatically adjust to the selected setting.
If the air suspension does not adjust properly, there may be a problem with the system. In this case, you should take your vehicle to a qualified mechanic.
