Start/stop - is it standard for B9?

[badgerjockey]

Hi,

Have just bought a 65 plate XTR and all going pretty well. Just wanted to know whether a start/stop function was standard on these or only applicable to some versions? Mine hasn't done it yet but I gather you need a pretty new and fully charged battery to do it. Any way of checking whether I should have the feature and whether the battery needs replacing?

Thanks,

H

if you have start/stop you will have a button with A symbol like in the image below
