How do you reset the service indicator on a 2005 Mercedes M350?

disconect your battery cable perferably the ground for 15 to 30 seconds and hook it back up it should reset your computer and cancel out your problem if it come back that means you have a problem and it is throwing code telling to go the computer to find out what is failing but only your mehcanic can do this for you. I hope this helps you, Wes
