2001 Oldsmobile Alero warning lights

Try this with the oil change light:

Sitting in the drivers seat with doors closed and key off, turn the key to the run position (do not start). Next press the gas pedal to the floor 3 times and wait for about 10 seconds. The light may flash, turn off, or you may hear a beep. Now turn the key off and back on to make sure it reset. Let me know if it didn't because some are reset through the radio.

Now the tire pressure light. Make sure the pressure is good in all tires (aprox 30 to 35 PSI). The light should reset itself, but if it doesn't, there may be a problem with a sensor. Have the computer scanned for codes to identify where the problem is coming from.
