This video shows you how to jump start a dead battery in your 2009 Mercedes-Benz C300. If you get into your C300, turn the key, and your car doesn't start (you may hear nothing or a clicking sound from the engine bay), you have a dead battery and need a jump-start. Check to see if you left your headlights or an interior light on and turn the switch off. Assuming that you have a pair of jumper cables, a pair of safety glasses and a friend to give you a jumpstart, the video above will show you where to connect the cables (and in what order!) for your C300. Once you are finished reviving a dead car battery in your C300, make sure you drive it for at least 5 minutes before turning it off so your battery isn't dead the next time.
So what's up with the safety glasses? There is a small possibility of a battery exploding during the charging process if you don't connect the cables properly (causing a spark) and there is a bunch of hydrogen gas around the battery (car batteries emit hydrogen gas when they discharge) - this is much more of an issue with cars that haven't been driven for a long time than if you drive your C300 regularly and simply forgot to turn your lights off.
