Can someone tell me if I can turn off my parking sensors?

Hi chaps,

Just had a towbar fitted on my Espace ( ) so I can tow the track car around.

Trouble is, as soon as I put it in reverse the sensors pick up the tow bar and give a solid beeping sound...

Is there a switch in the Espace to switch them off, or is there a way of disabling the middle 2 sensors, closest to the towbar, and leave the outside ones in operation?

Thanks in advance!

Sorry, I'll try a single bump...
