Need help resetting the maintenance service indicator on the 2007 GL450. I changed the oil at 6500 miles and reset the indicator 1st time (service A). Now the Service B light is on and odometer only reads 11,000 miles. I read the manual, it says light should not be reset for oil changes done outside of recommended service. I accidentaly reset it first time now it is out of sequence. Any help would be greatly appreciated.
