Hi, I cant find a reference to what the setting does? I got car second hand a P85 and it comes with winter pack - I was told it had heated seats (it has 5), heated washers (jets and blades) and heated steering wheel. Not had frost yet but in winter setting where you tun seat heaters on the windscreen can be pushed and shows red but not sure what it is doing - steering wheel doesnt get warm but MAY only hapen when near or below freezing outside.

Can anyone explain what I should expect when it gets cold please. The car was made December 2014.

Thanks. Rick.
