If level outside approved range is used, the vehicle will not assume the level and fault codes are saved.
Note:
The vehicle will move up and down when the air suspension is calibrated. It is therefore extremely important that no persons or equipment remain in the area around or underneath the vehicle, to prevent damage or injury.
Test conditions:
Ignition on with external air supply connected, or engine running.
Vehicle unloaded.
The vehicle must stand on level ground.
On vehicles with a lifting axle, this must be lowered.
Ensure that the button for the support shaft/load transfer and any alternative ride height (if the vehicle has this function) is released.
To prevent tension in the chassis during calibration, the parking brake must first be released. Secure the vehicle using chocks under the rear and front wheels before starting the procedure.
Procedure:
Raise the chassis to insert the spacers.
Place the spacers close to each bellows.
Lower the vehicle on the spacers using the buttons in the program.
Perform calibration.
Exit the function.
