In trailer mode, the parking pilot does not automatically switch off the sensors and acoustics. It is therefore possible that you will hear a continuous warning tone in the cab when reversing.
An additional trailer parking pilot, which is compatible with the HYMER parking pilot, is optionally available from the system manufacturer. In this case, the parking pilot recognises whether a trailer with an additional trailer parking pilot has been coupled and automatically switches to the trailer's reversing sensors. After uncoupling the trailer, the reversing sensors of the motorhome are automatically used again.
