Discovered that my ride has that function thru old thread.The function is very useful while reversing.now i can see the drain and curb..i think all f10 models have that function.look at your passanger's side mirror while reversing,see if it tilted down but make sure you put the switch as it you want to operate the driver's side mirror..
I dont know about the F10 but on the older model like the e39, only the ones with electric memory functions have this feature. i have electric folding side mirrors in my car with manual seats so this feature doesnt work.
My E39 does not have electric folding side mirror but with memory seat. mine come with this tilting function.
same as EL118...also comes with the automatic tilting side mirror. a good reason why a 2nd hand e39 makes much more sense than buying a brand new toyota dugong vios.
