How to get inclination angle input when doing Mercedes-Benz air suspension calibration?

On many Mercedes-Benz models, the inclination angles are not measured by the scanner itself. They usually need to be measured first with an inclinometer, and then those values are entered manually into the scan tool during the suspension or ride height calibration procedure. Depending on the specific chassis and drivetrain layout, the measurement point may be at the axle, control arm, or another specified suspension component. The exact location and target value can vary by model, which is why the proper method is to follow the vehicle-specific procedure and use the measured values rather than guessing. The UCAN-II supports guided service functions, but like dealer-level tools, it still relies on the technician to supply those measurements when the vehicle requires them. The scanner’s service functions are guided by on-screen prompts, and procedures vary by vehicle.

In real-world use, many owners do not have an inclinometer and do not know the correct measuring point, so some users try entering values near the middle of the allowed minimum and maximum range shown on the scanner until the procedure is accepted. That can sometimes work, but it is not the proper method, and it is not guaranteed to produce an accurate calibration. The better approach is always to measure the angle correctly for that exact Mercedes model. For customers who need a visual walkthrough, this video is a helpful reference.
