Hello, I have finally bought my Protege5 2003

The previous owner installed a front lip over the original front bumper, and I was considering removing it during the winter (I'm from Montreal, we can have some tough winters, I wouldn't wanna destroy the lip since it looks good).

I took a look at it, it has two screws underneath and one on each side, in front of each wheel. These are not a problem.
What I DID have trouble with though, is figuring out a way to get to the screws? attachments? (I'm not even sure what they are, couldn't get a good look at them) which are right behind where the Fog Lights normally are. I don't know how to get to them and how to remove them.

If anyone has any experience and could explain it to me it would be greatly appreciated.
(My time under the car wasn't wasted though, I also put new winter tires on it yay )

Thanks
