Toyota Corolla 2005 unknown button beside steering wheel,help?

http://www.facebook.com/photo.php?fbid=20181732987...

I own Toyota Corolla LE 2005.This button is situated at the left side of the steering wheel beside the side mirror controls as you can see in picture linked above. When i press this button, nothing happens but if I keep the button pressed for a few seconds then a icon of the same shape appears, blinking beside the rpm meter with a interrogation mark in it. Still nothing happens. Need Help ASAP

    Also if you have a full size spare tire it will have the sensor on it as well so if you fill up all 4 tires and the light is still on you will want to go check you spare tire as well before you go resetting the sensors.

    Its your TPMS

    Tire Pressure Monitoring System

    Basically if the light comes on when your driving then it means that one of your tires have lower pressure then what its set at. But if you hold it down long enough it resets the sensors and sets it at the PSI its at right now which you probably dont know. Best bet is to check the pressure in each tire and make sure its at the correct level then reset the TPMS so you wont have any false alarms.
