Park Distance Control 05 plate

Hi
Just picked up an 05 plate and regarding the PDC, I know you can turn this off and on, but when in reverse, the side mirrors aim down so you can see the kirb, but I'd rather this not happen and would like the mirrors to remain in the normal position - is there anyway I can do this?

Thanks

Not sure on yours but on the P38 yes, it's detailed in the handbook
