2016 ATS Luxury Edition. A door roughly above each headlamp housing. Not much to see inside. What are they for?

IIRC access to headlight adjusting screws.

Thanks for the reply. I see on white plastic piece with a phillips pattern. Assuming that's vertical, what do you do for horizontal?

 

[oemtech]

Again IIRC there is no left/right adjustment.

OBTW - don't lose the door as they are a PITA to find.

I think the left/right adjustment is that bit sticking off the back. You can't get to it with a philips head from the top, but, I think, a 7mm wrench will do it.

Thanks. Nothing made easy.

Haha, nope. Wait 'til you need to replace the battery. Much more difficult than it really needs to be, because Cadillac.

Yup you have to take most of drivers side trunk liner out.

I miss the days when, if you open the hood of a Cadillac, there was like a foot clearance around the engine and everything else was readily visible and accessible.

Thanks to all for the info. And yes, I've been wondering about the engineering decision to bury the battery so deep. As an aside question, is the battery vented in any way? On the BMW E39 i had prior to my ATS the battery was in the trunk under a very simple door and easy to get at. It was vented via a plastic tube to the right rear wheel well. E39's with defective right rear lighting suffered from corrosion caused by battery fumes rising from directly beneath the lighting assembly if the tube wasn't present or slipped off its connector.

The ATS also vents to battery through a small tube. Not sure where it leads, though.
