In the U.S. there is no rear fog lamps, and there are no regulations that I know of about when you can use forward facing fog lights. Of course, vehicle code is at the state level so it could be different in some states. As for my 2019 EC SEL, the fog lights work exactly as they did on my Outlander. To turn them on, the headlights must be on at the low beam setting. Then rotate the switch forward to turn them on, backwards to turn them off. If you switch to high beams, the fogs will turn off and come back on when you switch back to low beams. If you turn the headlights off, the fog lights go off too. If you turn the headlights back on, you must use the switch to turn the fog lights on. They do not come on automatically.

I could not find anything in the manual about automatic settings for fog lights. If your fog lights are coming on automatically with your headlights, something is connected improperly.

Us top spec 🇺🇸 model comes with fog light at rear. Low spec model EC comes with 2 red reflector ...upper trim comes with rear fog on driver side and red reflector on passenger side.
Ec with rear fog will come with same switch as outlander...however there are multiple ways of choosing how all light operate and I believe in Aries situation his model was set to operate as a day running light feature... its not any electrical wiring issue... its just settings... it can be set to use switch independent.
I believe I had selected this option where I opted for fog light to come on when I remote open asx/outlander sport ... but I change it back as I already had daylights and I prefer independent controll.... never done it on eclipse cross though.
Aries option is to ask a dealer tech to change preference ..hopefully he like you enough to do it for you otherwise find a programmer.
But its always good to have prior knowledge to tell dealer what you want to change ...than for them to spend long period of time searching for an option that might mess up your setting and then blame them to which they aren't getting paid to do.

I have an SEL with the touring package but I don't believe I have a rear fog light. I don't see anything in the manual about rear fogs. Are you saying they are installed but not active?

Honesyly i did not read manual ..lol
The wire are already install ...however if you don't have the rear fog switch ...I wouldn't advice you to even consider as the switch control will cost a bit... light unit are cheap.
After installing switch and light you will have to activate feature in etacs.
Check on rear fog/reflector lights if they are both clear (white+little red) then you dont have rear fog light...
so red reflector = rear fog light.

I plan on purchasing the reverse light for the left hand model so the when I turn on rear fog light its much brighter the the red fog light.... there's no law enforcement for doing such.... it will be more helpful in dark situation.

That’s what I was thinking, like I meantioned before. Spoke to the dealer and was told that my dog lights on 2018 SE eclipse Cross acts as day time running light. But as an type this right now I’m in my car and it’s 1:03 Eastern time and I have the lights on auto so the day time running lights are the only lights are on right now but not the fog lights like it has been running since I got the car. It’s just weird

It may be a programming issue as @Willisjamaica said. I'm unsure why the fogs would be used in addition to the DRL unless this was a rental car prior to you buying it. Their are different programming spec's for rentals. ie. automatic door locks. The SE came standard with fog lights so they would have been wired and tested at the factory. I agree. Weird.

Strange...Can the headlights and fog lights switch turn independently of each other?

Could be but like I said it's a weird system but as long as the fog lights are working,

All of a sudden this started happening in my vehicle as well. I can confirm that @stevenny's comment "...try keeping turning it off..." works. That is - when the fog lights refuse to turn off you need to keep trying...after several attempts they do turn off. My MEC has a rear fog lamp & I'm not operating the controls the the wrong way & no settings have changed. This is a real issue.

It effects both the rear & front fog lamps, the front ones are more stubborn for some reason.
