I have elegance 14plate.

I was just wonder did I have function mirrors down when I put on reverse gear?

If yes how I can set up?

You need to set it up, then turn the mirror knob to left mirror position and select reverse and should work.

If you have electric adjusting seats you have the mirror down function. The mirror positions are stored with the seat position when you change between users.

It's work only when is on position L and it's only left mirror going down and don't won't to pull up. To pull up I need to change position to 0 or cheating

The left mirror should go down when you select reverse and move back up after you switch off the engine or drive forward for a while. Or at least mine does anyway (With the mirror selector left in L all the time). 

So that's means mirrors will not be heated?

No the mirrors are only heated when the heated mirror position is selected.

 

The mirror will raise back up to the normal position when the ignition is turned off or when the car goes over something like 10 or 15 mph.

So to get this work position always have to be on L and it's only one mirror going down?

Yes I leave mine in the L position all the time. Only the passenger side mirror drops as it's meant as an aid in parking so you don't hit the kerb with your wheels.

 

The odd occasion I need the mirrors demisting I switch it to the heater position for a few minutes then move it back to L.
