I just picked up my S85 today. My three year old son and I went for a drive this evening. As we approached the vehicle, the handles presented. As I opened his door, the dome lights came on. I began buckling him into his car seat and the interior dome lights turned off... I had to turn on the flash light function on my phone in order to finish and then walk around to the driver's side. I realize in retrospect that I could have touched the light near his seat to turn it back on (and hopefully remember to turn it off again!), but I'm wondering if that's normal for the Model S. Do the interior dome lights really only stay on for a minute or two? Every other vehicle I've owned leaves the lights on as long as the doors are open. Thanks!
