press it and it sprays water over intercooler which intern means air going in is cooler and engine runs cooler, i think on some models its is temp controled and some you have to press to make it wotk although dont quote me on that

LOL Nope but i dont know where the bottle for it is though

 

Bottle is at front left of engine bay when you open the bonnet, says I/C on the lid.
Oh and goes down very quickly, but no point using it this time of year as the air is cold and damp already
