Should the side assist be deactivated automatically, a driver message will appear in the instrument cluster display:

The system cannot detect vehicles reliably and will be deactivated. The sensors are out of alignment or defective. Have the system checked by a qualified workshop soon.

The radar sensors are blocked. The area in front of the sensors must not be obstructed by bicycle racks, stickers, leaves, snow or any other objects. If necessary, clean the area in front of the sensors Fig. ►.

The side assist is temporarily inoperative and cannot be switched on (for instance if the battery is not sufficiently charged).

The side assist function will be switched off automatically when the electrical connector for the trailer socket is plugged in on vehicles with a factory-fitted towing bracket. If the towing bracket is not factory-fitted the side assist function may not be switched off automatically. The side assist and exit warning systems must not be used when towing a trailer.

The rear cross-traffic assist is not available. Either the ESC is switched off or the radar sensors may be obstructed by a bicycle rack, stickers, leaves, snow or similar objects. Switch on the ESC or, if necessary, clean the area in front of the sensors Fig. ►. If this message remains displayed, drive to a qualified workshop soon and have the fault rectified.
