Before you turn the light off (you can do it yourself and without a code reader using the accelerator method detailed in the FSM and likely somewhere on this forum), you want to find out what code(s) triggered the light in the first place. If you don't feel comfortable reading the codes yourself (the DIY method I just mentioned without a code reader is a little convoluted and some people apparently haven't had the coordination needed to make it work at all) most auto parts places will do it for you.
But I do agree that the first time you get a SES light, after you get the code(s), merely reset the light and see if it returns. That is, of course, provided your car is still running OK. If you're having driveability problems, you likely have something more than some fluky thing that set the SES light on and you should have a qualified technician check it out.
I had a similar situation with my 04 SE a few years ago. I read the code out in my garage using the accelerator method, reset the light, and it never came back on.
