Since I'm quite a fan of Canon's for their ease of use and similarity from model to model I think I can help you find your ISO setting.
If you don't see the current ISO setting on your camera press the DISP. button, it should show along the left side of your screen with a bunch of other icons and say something like ISO 100 or something along that line. Higher numbers is faster but grainier. Your model camera will go up to an ISO of 400.
Try pressing the FUNC. button, according to that website it should be located just below your viewing screen and on the right side. Scroll through the options on the left until you get to the ISO then you should be able to hit the SET button (that's the button in the center of the large circle on the back of the camera on the right side. Once you access that you should be able to change the ISO setting to whatever you want.
Hope that helps, that website is a great tool for learning about your camera. I've found for mine it sometimes has features listed that aren't even in my manuals.
