The warning signal shall be constant or flashing.

4.5.3. The vehicle user's handbook provided by the manufacturer should warn the driver of the consequences of manual disconnection or mode change of the anti-lock braking system.
4.5.4. The device referred to in point 4.5 may, in conjunction with the tractor, disconnect/change the control mode of the anti-lock braking system of the towed vehicle. A separate device for the towed vehicle alone is not permitted.
4.5.5. Devices changing the control mode of the anti-lock braking system are not subject to point 4.5 if in the changed control mode condition all requirements for the category of anti-lock braking system with which the vehicle is equipped are fulfilled. However, in such a case, points 4.5.1, 4.5.2, and 4.5.3 shall be met.
