Hello DS owners, new member here 
I would like to ask you if anyone knows what is this for from the title in DS4 since I have no idea and didn’t notice any changes when it’s turned on or off?
Thank you for any insight and help guys!
Welcome Zirna!
This feature should make the daylight running lights (the white LED bars on the front-sides) do a little ‘dance’ when you approach or move away from the car. The welcome function in my experience always works, the bye-bye one only in darkness I believe.
Hi x3n0n10
Thank you for the explanation, I ll try to catch that for exterior, and then there is also interior animation as well. I noticed only bye bye, colored DS Automobiles animation with sound, but for the welcome only standard White and Grey DS Automobiles without sound (present always either welcome/bye bye on or off). So yeah it’s a bit confusing how it works or doesn’t work since every system update can bring new glitches.
Oh right I forgot about those logo animations on the screens and the sounds! You’re right about that, updates could change the functionality, then it’s up to us to figure out what they’ve changed exactly
