How to turn off the low tire pressure light? on 2004 Buick Century

I inflated all tires to correct pressure, but the light won't go out.

BOTH #1 & #2 are correct. My concern is what you are calling the 'correct pressure'. Are you going by the door jam label/owners manual specs or are you reading the 'max inflation' spec on sidewall of tire. Being over-pressure will cause some TPMS lights to come on , as well as being low.
Thanks to all for your great suggestions! Will try them all.
theres button in glove or under dash on buick,olds...wow...
Read owners manual.
CK ALL TIRE PRESSURES EVEN THE SPARE PEOPLE TEND TO FORGET THE SPARE TIRE AT TIMES HAS A SENSOR ALSO. IF THEY ARE ALL AIRED UP SEEK A DIAG AND EST YOU MAY HAVE A BAD SENOR. IF YOU FIND A LOW TIRE DRIVE CAR APPROX 2 MILES AFTERR FILLING AND IT SHOULD RESET
