This function is used to initiate the fully automatic towbar. This can be done in two ways, through diagnosis and manually via the control button in the vehicle. If the initialization is lost, the red LED, on the control button, flashes or illuminates.
If the towbar stays in an end position, you must release the button briefly and then press it again until the other end position is reached. The LED flashes until the initialization is complete, then it illuminates green.
