The F10 has sidemirrow and windscreen washer jet electric heaters.
But how do they work?
1. Automatically when the temperture goes under some certaine temperature or
2. When you switch on the rear window heating or
3. Something else?

Thanks luigi524td for the rapid answer.
What may be the temperture when this should happen?
Like +3C (37F) or something else?
It's now -10C (14F) here and we have some problems with the nozzles...

My recollection is 37 degrees F ... are you using washer fluid with de-icer? The commercial mixes generally protect to -20 degrees F. Or maybe your nozzles are blocked with crud. Use a some canned air (the stuff used to blow dust from PC's etc) and shoot a blast into the nozzle.

There's not a problem with the washer fluid nor the nozzles (except for the nozzle warmer).
We're expecting below minus 5 F early next week. Coldest November in 100 years or even longer.
I was however a bit concerned about the head light washers though... as I recall, they are not supposed to be active at such low temperatures.
I imagine that the pop-up mechanism could be damaged if the washers are frozen shut.

They don't have any heating systems, as they should have.
- 20 C here next week :thumbsdown:
I didn't find anything in the swe manual regarding the washer nozzles other than that they are heated....nothing about when the heating function is activated.
It is also interesting to see that some manuals state that the rear cam is heated too. My manual say nothing about that.

I haven't looked in the manual yet...but I've used the window washers today with -10 C outside.They worked just fine.

Drove ~ 280KM today with an average temperature of -7 and the windscreen washers didn't work, nor did the headlight washers.
Bit of a pain in freezing fog with crap hitting the window and windscreen wipers rigid like wood scraping across the screen with nothing to help them..... maybe your Scandinavian Spec cars get better winter equipment???
