Hi All, I'm a newbee, so please be polite

I got my 2013 S60 just a few days ago, it has many features including "Speed sensitive steering",

the thing is I notice no difference between steering settings low -> mid -> high.

How is it supposed to work?, I thought that the "High" should be the higher support to the steering which makes it softer than other settings.

Could you tell me how this normally works, what difference I should see between settings so I can be sure it has no problem,
thank you.
