I have owned my 2004 CLK 500 for less than a week and put less than 500 miles on it... But when driving today the yellow "check engine" light came on. The car has 45k miles and the next schedule A maintenance is due in 9600 miles.
There were ways to check the diaganostics on other cars I have owned and I am sure there is a way to get to the car's diaganostics to determine what the check engine light is saying. I do not have a shop manual so can someone direct me on how to access this information and where I might find a key to the codes that are displayed? I would hate to think that everytime something like this happens you need to head to a dealership... that would get pretty expensive pretty quick.
Thank you for any help in determining this....

I went to the local Autozone and had them check the code... turned out to be a P0456... I checked the gas cap and had him clear the code. Now time will tell if it comes back or not. I did look into the code someone elsewhere on this site said that the slow leak may take time to come back up.
