I would also assume that your shades are the same as on my 2015 Sunstar. If so, haiduan is correct.
Although the side valances(?) don't need to come off, I found it easier with them off. It's easy, two phillips head screw on each side. You'll probably need to lay on your back with a flashlight to see the clips and a long thin blade straight screwdriver to release the clips.
You should be able to find a video on the adjustment for them, maybe even on MCD site. The only other thing I can think to mention is that when you put them back up, make sure they are centered left to right so neither side drags on the valences. Don't ask how I know this.
Good luck. Although it's not a job I would want to do frequently, it's doable.
