turn the key to "on" and open the fuse panel to the left of the steering wheel when drivers door is open, hold the "reset" button until the oil light on the dash starts to blink and then push it again, you should hear the chimes and then the light will go off. :-)

There are 4 key ignition settings: Off, Acc, On, Start Turn key to the On position, quickly press the gas pedal 3 times, then turn key clockwise to Start position and actually start the car. You'll hear it chime at you and the change oil indicator light will flash and disappear.
The tire light....Have you checked all your tires for prper air pressure? including the spare? If they all have the maunfactures recomended PSI. Remove the negitive post from the battery for 20 min. to rest puter. If that dont work you have a faulty TPMS on a tire need a new one. Hope this helps
SOURCE: Does anyone know how to reset the
Turn the key ahead to run mode, without cranking and push gas pedal to floor and back up 3 times within 5 sec, this should reset the oil change light. as for the tire pressure light there are a couple of procedures, but ensure first that the pressures are all above 28 psi, and are the same. however, without the use of a tpms tool to communicate with the tire monitor sensors it may not reset. did you have any tires changed over, or rotated? if so the use of the tpms tool is much easier to reset the light. Probably better off bringing to a tire or mechanical shop that deals with it regularly. It is actually not that difficult, but the tool will allow you to tell if a sensor is faulty, or has a weak battery, etc.. hope this helps
