Do I need to reset the Tire Pressure Monitoring System after a flat tire?

[matrix_luver]

Hi,
My Tire Pressure Monitoring System (TPMS) went on 2 days ago on my '10 Matrix after I drove over a nail and then had a flat tire. I got the tire repaired now and once I put that tire back on to my car, the indicator light went off immediately.
I am now wondering whether I still have to press the reset botton for the TPMS to reset the system with the new tire pressure or whether it resets itself once all tires are back on the car?
The other "issue" that I have is that I cannot find the reset button, but the car's manual is saying that is is under the steering wheel (right hand side)???

Any idea anyone?

Thanks!!!

umm, im not really sure what i did when my tire went flat half a year ago, but i believe i did click the reset button. its down under the foot well area. just stick your head down to the carpet and look up. you'll find a button that says something about tire pressure.

Thanks, I actually found it yesterday but I haven't pressed the button yet. Don't wanna srew up the system by doing something that I am not sure about. Called the dealership and they said I have to stop by for them to check the tire. They couldn't tell me whether it needs to be reset or not. Geesh...
