i know that you have to turn it to the white dot position for the mirrors to fold manually but it has a function for the mirrors to close automatically when the car is locked with the key card.
The automatic closing of the door mirrors worked fine until the battery was changed,there is probably a certain procedure of turns of the mirror knob to reset the feature.
The automatic folding mirrors were a optional extra when the car was new and i have contacted two renault dealers who did not even know that the folding mirror were available on my 197 and Renault Uk also has no idea, and all handbooks that came with the car contain no information so any useful help to solve this issue would be appreciated or i will have to brush up on my french so i can speak to the Renault Sport Factory in Dieppe !!
