2021 Hybrid LE - What should be in D/L No. 2?

[matcha_is_just_grass]

I own a Hybrid LE and I checked the rear compartment out of pure boredom at my apartment (I have remote corporate work so imagine the loneliness). So yeah, when I checked, there was an indicator on the lid pointing that the component underneath should be the D/L No. 2. First off, what is that supposed to be? There's none in there but I'm trying to locate an empty fuse slot for a subwoofer. It should be 15A if I read it correctly, so it should be fine and safe to use to power my sub. Is my understanding correct? Anyway, upon checking, I also saw that the fuses indicated as Batt Fan No. 2 and ECU-B No. 3 are both vacant. Is that something to be worried about or it's just fine? Maybe my car doesn't have those accessories but I am quite alarmed because... a fan is a fan. Might be needed. Can you guys please enlighten me more before I do something that might mess it all up (lol). Thanks!

The D/L no. 2 should be door lock no. 2, it goes all the way to the 12V battery. I've checked it out in the service manuals, it didn't indicate that it provides power for anything. Probably a future feature, anyway... you should relax, there's nothing to worry about.
