Hi all,

I have recently purchased a 2010 X5 and got 2 spare keys but also a very strange looking 3rd key? I spoke to the dealer and he said its for defrosting the car without starting the engine. I know this might sound thick but is it just a case of pressing the "ON" key and then it defrost itself or is there a procedure to follow or even a different use altogether? 

Thanks in advance 👍

Perhaps check the Manual?

The following mentions the X5 possibly having an additional heater.

Alternatively go back to the dealer and ask for a more detailed explanation or even a demonstration.

Hope this helps.

John

P.S. There is also quite a detailed discussion on this site in the X5 forum. It's on the 8th page and is titled Aux Heating Programming, dated Oct 2012.
