My service indicator came on today with a -124. I've only put 4400 miles on it since buying it from the dealership, so this will be my first service date. My question is, what does "service" mean. Just an oil change? Oil change and tune up? Lube job?..Etc....Just what does "service' entail? and does it have to be done by the dealer since it's the first one?..Thanks, any info will be welcomed.
