Guys, the Maintenace Required Light (MRL) is entirely different than the Check Engine Light (CEL). If, in fact, it is the MRL, it is not a big deal. The MRL comes on at pre-determined intervals to remind you to do scheduled maintenance (I believe every 7,500 miles). There is a MRL re-set switch under the dash (under the wheel on the right side; above the gas pedal). If, in fact, it is the CEL........then you likely have some other "issue" and you need to pull the code to decifer what is wrong and go from there. FYI - AutoZone will pull the code for free if you don't want to try and get it yourself.
