there is no reset button, it must be done with an obd2 code scanner ^^ that will probably cost money, easiest way to reset is to disconnect the battery for 15-20 minutes...reconnect and your codes are now lost (which is good) unless of course you do have a problem. In which you light will come back in about a day anyway... The MIL trips are it fails a 'routine.' Some routines take longer to complete than others... that is, you have to perform some common driving maneuvers, other routines run every time you start the car. These same routines can also clear the MIL, if they run without failing 3 times or so. So you don't always have to clear the DTC codes with the OBDII scanner or power loss (disconnect battery), sometimes they clear themselves.
