The emergency steering can be used continuously for a maximum of 60 seconds. Operating it continuously for more than 60 seconds may damage the system. When using the emergency steering, travel at less than 5 km/h (3.1 MPH). If the steering becomes heavy, keep the emergency steering switch pressed, move the machine immediately to a safe place, then stop the machine. During emergencies or when stopping the engine to check the function, press emergency steering switch (1).
